Description

TECHNICAL FIELD

[0001] The utility model relates to ejector production technical field especially, and it relates to a kind of ejector injection capacity detection system and ejector block production system. BACKGROUND

[0002] In the evaporator of full-liquid type water chiller unit, the lubricating oil enriched on the surface of refrigerant cannot automatically return to the compressor, which is a key problem to be solved. If the lubricating oil cannot return in time, it will seriously interfere with the normal operation of the unit. At present, the injection oil return method is a common solution, that is, using high-pressure liquid in the liquid accumulator or high-pressure gas at the outlet of the compressor as a high-pressure working fluid to extract the lubricating oil in the full-liquid evaporator back to the compressor. In the injection oil return loop using high-pressure liquid in the condenser as a high-pressure working fluid, the liquid-liquid ejector plays a key role, and its working state directly affects the oil return capacity and thus the long-term stable operation of the compressor.

[0003] However, there are many defects in the field of ejector injection capacity detection at the present stage. On the one hand, there is a lack of effective detection methods and unified standards. During the operation test of the water chiller unit, only qualitative analysis can be carried out by measuring the temperature difference before and after injection. This method not only has a detection lag, but also takes a long time to rework once a problem is found, greatly prolonging the test period and delaying the production progress of the unit. On the other hand, qualitative analysis has loopholes and cannot accurately identify all unqualified ejectors, resulting in frequent oil leakage failures caused by poor performance of the ejector after sale, which seriously affects the normal use of the unit and user experience, and increases maintenance cost and equipment failure risk.

[0004] Therefore, it is necessary to improve the existing ejector injection capacity detection method to overcome the defects of the prior art. UTILITY MODEL CONTENTS

For example, when the gas supply source contains small particle impurities, the impurities are blocked when the gas passes through the filter cartridge, so that the gas entering the injection end of the ejector is pure. Moreover, the filter cartridge is detachable, so that it is convenient to clean or replace after being used for a period of time.

[0021] In the preferable technical scheme of the utility model, the filter cartridge is provided with a first filter screen and a second filter screen, and the first filter screen is arranged on the periphery of the second filter screen along the radial direction of the filter cartridge.

DETAILED DESCRIPTION

[0037] Preferred embodiments of the present application will be described in more detail with reference to the drawings. Although preferred embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present application more thorough and complete, and to convey the scope of the present application to those skilled in the art.

[0038] In the evaporator of the flooded water chiller unit, the lubricating oil enriched on the surface of the refrigerant cannot automatically return to the compressor, which is a key problem to be solved. If the lubricating oil cannot return in time, it will seriously interfere with the normal operation of the unit. Currently, the ejector oil return method is a common solution, that is, using high-pressure liquid in the liquid accumulator or high-pressure gas at the outlet of the compressor as a high-pressure working fluid to suck the lubricating oil in the flooded evaporator back to the compressor. In the ejector oil return loop using high-pressure liquid in the condenser as a high-pressure working fluid, the liquid-liquid ejector plays a key role, and its working state directly affects the oil return capacity, and then affects the long-term stable operation of the compressor.

[0039] However, there are many defects in the field of ejector injection capacity detection at present. On the one hand, there is a lack of effective detection methods and unified standards. When the water chiller is running, only the temperature difference before and after the injection can be measured for qualitative analysis. This method not only has a detection lag, but also takes a long time to rework once a problem is found, greatly prolonging the test cycle and delaying the production progress of the unit. On the other hand, qualitative analysis has loopholes and cannot accurately identify all unqualified ejectors, resulting in frequent oil running failures caused by poor performance of the ejector after sale, which seriously affects the normal use of the unit and user experience, increases maintenance costs and equipment failure risks.

[0040] Based on this, the application provides an ejector injection capacity detection system.

[0041] Embodiment 1

[0042] Referring to Figs. 1-3 The ejector injection capacity detection system provided by the embodiment includes:

[0043] The first branch is connected to the injection end, and the second branch is connected to the injection end. The first branch includes a pressure regulating module 1, a first filter 2 and a first flow meter 3 connected to each other. The pressure regulating module 1 is externally connected to a gas source, and the first flow meter 3 is in communication with the injection end.

[0044] The second branch includes a second filter 7 and an ejector production technology field connected in sequence. The second flow meter 6 is in communication with the injection end.

[0045] Specifically, the first filter 2 is used to filter impurities in the gas provided by the gas source, to ensure that the gas entering the ejector 5 is pure, to avoid damage to the ejector 5 and to affect the detection results. The flow meter is in communication with the injection end, which can accurately measure the gas flow entering the injection end. For example, the pressure regulating module 1 can use a high-precision pressure regulating valve to accurately regulate the pressure of the gas source in the range of 0-1 MPa; the filtering accuracy of the first filter 2 can reach 0.1 μm, which can effectively filter common small particle impurities; the flow meter selects a mass flow meter, and the measurement accuracy can reach ±0.5%.

[0046] The second branch is connected to the injection end of the ejector 5, and the second filter 7 is also used to filter impurities in the gas entering the injection end to ensure the purity of the gas. The second flow meter 6 is in communication with the injection end and is used to measure the flow of the gas entering the injection end. For example, the filtering accuracy of the second filter 7 is the same as that of the first filter 2, which is 0.1 μm; the second flow meter 6 is of the same type as the first flow meter 3, and the measurement accuracy is also ± 0.5%. The two different branches are used to simulate the working conditions of the ejector 5. For example, the first branch is connected to the medium-pressure air, and the second branch is connected to the atmosphere, which respectively replaces the high-pressure liquid and the lubricating oil of the ejector 5 of the refrigeration system, so that the system can simulate the working conditions of the ejector 5 in actual operation.

[0047] The detection system automatically measures the flow of the gas entering the injection end and the injection end by setting two independent and functionally clear branches, and simulates different working conditions in combination with the pressure regulating module 1, thereby realizing the automation of the detection of the injection capacity of the ejector 5. Compared with the traditional manual detection method, the detection time is greatly shortened. High-precision detection helps to find problems of the ejector 5 in small performance differences, and provides strong support for product quality improvement.

[0048] Moreover, since the injection capacity of the ejector 5 can be accurately detected, problems of the ejector 5 can be found in time in the production link, and abnormality in subsequent tests caused by problems of the ejector 5 can be avoided. In particular, in application scenarios such as refrigeration equipment, problems of the ejector 5 can be eliminated in advance, which can effectively reduce the incidence of after-sales failures, reduce after-sales maintenance costs and user complaints.

[0049] In the embodiment, an electromagnetic valve 4 is arranged between the first flow meter 3 and the injection end and between the second flow meter 6 and the injection end.

[0050] The electromagnetic valve 4 is used to control the on-off of the different branches.

[0051] The electromagnetic valve 4 is arranged between the first flow meter 3 and the injection end. The electromagnetic valve 4 is used to control the on-off of the gas in the branch, and can realize accurate control of the gas entering the injection end. For example, the electromagnetic valve 4 can be closed before detection to prevent the gas from accidentally entering the ejector 5 and affecting the preparation work for detection; during the detection process, the electromagnetic valve 4 can be opened or closed in time according to the detection process and requirements, to ensure the smooth progress of the detection process. In addition, the arrangement of the electromagnetic valve 4 enables more detection data under different working conditions to be obtained during the detection process. By analyzing the performance data of the ejector 5 under different on-off combinations of the branches, the injection capacity of the ejector 5 can be evaluated from more dimensions, and richer data support can be provided for performance optimization and quality improvement of the ejector 5.

[0052] Embodiment 2

[0053] This embodiment is an optimization based on embodiment 1.

[0054] Referring to Figs. 1-3 In the embodiment, the pressure regulating module 1 comprises a pressure stabilizing valve 8, a first pressure regulating valve 9 and a second pressure regulating valve 10 connected in sequence, the pressure stabilizing valve 8 is connected with a gas source, and the second pressure regulating valve 10 is communicated with the first filter 2.

[0055] Further, in the embodiment, the pressure regulating precision of the second pressure regulating valve 10 is higher than that of the first pressure regulating valve 9.

[0056] In an embodiment, the first pressure regulating valve 9 is a mechanical pressure regulating valve, and the second pressure regulating valve 10 is an electronic pressure regulating valve.

[0057] Specifically, the high-precision pressure stabilizing valve 8 is selected in the embodiment, which functions to stabilize the gas pressure output by the external gas source and reduce the influence of pressure fluctuation on subsequent detection. The pressure stabilizing valve 8 is directly connected with the gas source, and can preliminarily stabilize the unstable pressure of the gas source within a certain range to provide a relatively stable gas source for subsequent pressure regulation. For example, if the pressure of the gas source fluctuates between 0.5-1.2 MPa, the pressure stabilizing valve 8 can stabilize it within the range of 0.9-1.0 MPa.

[0058] The first pressure regulating valve 9 is connected after the pressure stabilizing valve 8, and its pressure regulating range is set to 0-1.5 MPa, which can preliminarily regulate the pressure of the gas after pressure stabilization and roughly adjust it to the target detection pressure value. For example, for the case that the target detection pressure is 0.8 MPa, the first pressure regulating valve 9 can first regulate the pressure to the range of 0.7-0.9 MPa.

[0059] The second pressure regulating valve 10 is connected with the first pressure regulating valve 9 and communicated with the first filter 2. The second pressure regulating valve 10 has higher pressure regulating precision and can accurately regulate the pressure to the target detection pressure value on the basis of the preliminary regulation by the first pressure regulating valve 9. For example, its pressure regulating precision can reach ±0.01 MPa, which can accurately adjust the 0.7-0.9 MPa pressure regulated by the first pressure regulating valve 9 to 0.8 MPa.

[0060] In use, the gas source is opened, and the gas first passes through the pressure stabilizing valve 8 to preliminarily stabilize the unstable pressure of the gas source. Then, the gas passes through the first pressure regulating valve 9 for preliminary pressure regulation to roughly approach the target detection pressure. Then, the second pressure regulating valve 10 accurately regulates the pressure to the target value on the basis of the regulation by the first pressure regulating valve 9, such as accurately regulating the pressure to the target value for a certain type of ejector 5. The regulated gas enters the first filter 2 to remove impurities, and then the flow rate is measured by the flow meter.

[0061] Embodiment 3

[0062] The embodiment is optimized on the basis of embodiment 1.

[0063] Referring to Figs. 1-3 In this embodiment, the first filter 2 comprises a first casing 21 and a second casing 22 connected to each other, the first casing 21 is provided with an air inlet 211, and the second casing 22 is provided with an air outlet 221.

[0064] The second casing 22 is provided with a detachable filter cartridge 23, and the first casing 21 is sleeved on the periphery of the filter cartridge 23.

[0065] The first filter 2 is composed of a first casing 21 and a second casing 22 connected to each other. The first casing 21 is provided with an air inlet 211 for accessing the gas adjusted by the pressure regulating module 1. The second casing 22 is provided with an air outlet 221, and the purified gas flows out of the air outlet 221 and enters the subsequent flow meter.

[0066] The first casing 21 is sleeved on the periphery of the filter cartridge 23, so that after the gas enters the air inlet 211 of the first casing 21, it will be filtered by the filter cartridge 23, and the impurities will be intercepted in the filter cartridge 23, and the pure gas will flow out of the air outlet 221 of the second casing 22. For example, when the gas source contains small particle impurities, these impurities are blocked when the gas passes through the filter cartridge 23, ensuring that the gas entering the injection end of the ejector 5 is pure. Moreover, the filter cartridge 23 is detachable, which facilitates cleaning or replacement after a period of use.

[0067] More specifically, the second casing 22 is provided with a detachable filter cartridge 23 with a filtering precision of 0.05 μm. The first casing 21 is sleeved on the periphery of the filter cartridge 23, so that after the gas enters the air inlet 211 of the first casing 21, it will be filtered by the filter cartridge 23, and the impurities will be intercepted in the filter cartridge 23, and the pure gas will flow out of the air outlet 221 of the second casing 22. For example, when the gas source contains small particle impurities, these impurities are blocked when the gas passes through the filter cartridge 23, ensuring that the gas entering the injection end of the ejector 5 is pure. Moreover, the filter cartridge 23 is detachable, which facilitates cleaning or replacement after a period of use.

[0068] Furthermore, in this embodiment, the filter cartridge 23 is provided with a first filter screen 231 and a second filter screen 232, and along the radial direction of the filter cartridge 23, the first filter screen 231 is arranged on the periphery of the second filter screen 232.

[0069] The first filter screen 231 is arranged at the periphery of the second filter screen 232. The first filter screen 231 has a larger mesh size, for example, a mesh diameter of 0.1 μm, and is mainly used to intercept larger particles of impurities, playing a role of preliminary filtration and reducing the filtration burden of the second filter screen 232. The second filter screen 232 has a smaller mesh size, reaching a filtration accuracy of 0.05 μm, and is used to further filter fine impurities and ensure the purity of the outflowing gas.

[0070] In the embodiment, one end of the first shell 21 is provided with a first flange plate 212, and the sidewall of the second shell 22 is provided with a second flange plate 222, and the first flange plate 212 corresponds to the second flange plate 222.

[0071] The first filter 2 is composed of the first shell 21 and the second shell 22 connected to each other. One end of the first shell 21 is provided with a first flange plate 212, and the sidewall of the second shell 22 is provided with a second flange plate 222, and the first flange plate 212 corresponds to the second flange plate 222. By means of connecting members such as bolts penetrating through corresponding bolt holes on the two flange plates, the first shell 21 and the second shell 22 can be tightly connected together, facilitating disassembly and installation. The first shell 21 is provided with an air inlet 211 for connecting the gas adjusted by the pressure regulating module 1. The second shell 22 is provided with an air outlet 221, and the purified gas flows out from the air outlet 221 and enters the subsequent flow meter.

[0072] It should be noted that the structure of the second filter 7 can be the same as that of the first filter 2.

[0073] Embodiment 4

[0074] The embodiment is an optimization based on the embodiment 1.

[0075] Reference should be made to Figs. 1-3 In the embodiment, a pressure sensor is arranged on each of the first branch and the second branch, and the pressure sensor is located downstream of the flow meter in the flow direction of the gas flow.

[0076] In the embodiment, a controller is further included, and the controller is electrically connected with the pressure sensor, the first flow meter 3 and the second flow meter 6.

[0077] In the first branch or the second branch, the pressure sensor is located downstream of the flow meter in the flow direction of the gas flow. The pressure sensor is used to monitor the pressure of the gas after flow measurement in real time and feed back the pressure data. For example, the gas pressure can be accurately measured, and the accuracy can reach ±0.005 MPa, providing a pressure parameter for evaluating the working state of the ejector 5.

[0078] During use, the controller collects pressure data from the pressure sensor and flow data from the flow meter, and analyzes these data through a preset algorithm. For example, according to the standard parameters of different ejectors 5, the controller can determine whether the current ejector 5 meets the standard of the ejecting capacity, and issue corresponding control instructions according to the analysis results, such as controlling the pressure regulating module 1 to adjust the pressure, or marking the ejector 5 that does not meet the standard.

[0079] Embodiment 5

[0080] Referring to Figs. 1-3 , the embodiment provides an ejector 5 block production system, which includes the ejector ejecting capacity detection system as described above.

[0081] The production system can include:

[0082] Forming equipment: high-precision injection molding machines or die casting machines are used to process plastic or metal materials into the initial shape of the ejector 5 block according to the design requirements of the ejector 5 block. For example, for the ejector 5 block made of plastic material, the injection molding machine precisely controls the temperature, pressure, and injection molding time to ensure the forming precision and quality of the ejector 5 block.

[0083] Machining equipment: for the formed ejector 5 block, further machining such as drilling and milling may be required to meet the dimensional accuracy and assembly requirements. For example, a numerical control milling machine is used to process the surface of the ejector 5 block to achieve the specified flatness and smoothness.

[0084] Ejector ejecting capacity detection system:

[0085] The detection system, as described above, includes a first branch and a second branch connected to the injection end and the ejecting end of the ejector 5, respectively. The first branch includes the pressure regulating module 1 (the pressure stabilizing valve 8, the first pressure regulating valve 9, and the second pressure regulating valve 10), the first filter 2 (with the first housing 21, the second housing 22, the detachable filter cartridge 23, and the double-layer filter screen), the flow meter, the pressure sensor, and the electromagnetic valve 4; the second branch includes the second filter, the second flow meter 6, the pressure sensor, and the electromagnetic valve 4. In addition, the system is also equipped with a controller that is electrically connected to the pressure sensor, the first flow meter 3, and the second flow meter 6.

[0086] The production system can also include:

[0087] Automatic conveyor belt: used to smoothly transport the completed ejector 5 block from the production equipment to the ejector ejecting capacity detection system. The speed of the conveyor belt can be adjusted according to the production rhythm to ensure that the ejector 5 block enters the detection system in an orderly manner. For example, when the production speed of the production equipment increases, the speed of the conveyor belt is correspondingly increased to ensure the continuity of the production process.

[0088] Mechanical arms: At the entrance and exit of the detection system, mechanical arms are installed. The mechanical arm at the entrance is responsible for accurately placing the ejector 5 blocks on the conveying belt to the designated position of the detection system; the mechanical arm at the exit sorts and transports the ejector 5 blocks to different areas according to the detection results.

[0089] The production system can also include:

[0090] Finished product area: When the ejector 5 block detection system detects that the ejector 5 block meets the preset standard, the mechanical arm at the exit transports it to the finished product area. The finished product area is equipped with shelves to store the qualified ejector 5 blocks according to certain rules, facilitating subsequent packaging and shipping.

[0091] Unqualified product area: If the detection result shows that the ejector 5 block does not meet the standard, the mechanical arm transports it to the unqualified product area. The unqualified product area is also equipped with corresponding storage devices to store the unqualified products for subsequent analysis of the reasons for unqualification.

[0092] Detection control: The control system works with the controller of the ejector 5 block detection system to adjust the production process according to the detection results. For example, if multiple ejector 5 blocks are detected as unqualified in succession, the control system can automatically reduce the production speed of the production equipment and prompt the operator to check and maintain the production equipment.

[0093] Working process:

[0094] First, the production equipment processes raw materials into ejector 5 blocks. The molding equipment processes the materials into the initial shape according to the preset parameters, and then the machining equipment further processes them to improve the dimensional accuracy and surface quality.

[0095] The finished ejector 5 blocks are transported to the ejector 5 block detection system by an automatic conveying belt. After the mechanical arm at the entrance places the ejector 5 blocks at the designated position of the detection system, the detection system starts working. After the gas is adjusted by the pressure regulating module 1 and filtered by the filter, it enters the injection end and the suction end of the ejector 5 through the first branch and the second branch, respectively. The flow meter and pressure sensor collect real-time flow and pressure data, and the controller analyzes and processes these data to determine whether the ejector 5 block meets the standard.

[0096] According to the detection results, the mechanical arm at the exit transports the ejector 5 blocks to the corresponding area. Qualified products are transported to the finished product area, and unqualified products are transported to the unqualified product area. At the same time, the control system adjusts the production equipment according to the detection results to ensure that the entire production system runs continuously and stably, producing high-quality ejector 5 blocks.

[0097] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings. In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0098] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0099] In addition, it needs to be explained that the use of "first", "second" and the like to limit the parts is only for the convenience of distinguishing the corresponding parts, and the above words have no special meaning if there is no further declaration, so it cannot be understood as a limitation on the protection scope of the present application. The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
