Description
Technical Field
[0001] This utility model relates to the technical field of material pump monitoring devices, and in particular to a material pump monitoring and compensation device. Background Technology
[0002] The normal operating flow rate range of the sealing water in the material pump is 0.00025 GPM-0.00030 GPM, which translates to 1.143 L / min to 1.361 L / min. The normal temperature range of the sealing water before cooling is 16-18℃, and the normal outlet temperature range after cooling is 21-23℃. Currently, the material pumps lack flow and temperature monitoring for the sealing water, relying solely on operator experience to adjust the flow rate without standardized procedures. The sealing water pipe is directly installed in the floor drain; excessive flow wastes sealing water and can negatively impact the seal. When the sealing water flow rate falls below the limit, the mechanical seal may be damaged, the compression spring may break, and air leakage in the pipes may cause the sealing water to be drawn away by the negative pressure of the evaporator. Insufficient sealing water cannot adequately cool the mechanical seal, leading to overheating. If this is not detected promptly, it can reduce the pumping capacity of the material pump, even causing pump damage, disrupting normal production, and resulting in economic losses.

[0032] Example 1
[0033] The existing material pumps lack flow and temperature monitoring for the sealing water, relying solely on operator experience to adjust the water volume without standardized procedures. The sealing water pipes are directly installed in the floor drain; excessive flow wastes sealing water and can negatively impact the seal. When the sealing water flow falls below the limit, the mechanical seal may be damaged, the compression spring may break, and air leaks in the pipes may cause the sealing water to be drawn away by the negative pressure of the evaporator. Insufficient sealing water cannot adequately cool the mechanical seal, leading to overheating. If this is not detected promptly, it can reduce the material pump's pumping capacity, even damaging the pump itself, disrupting normal production, and causing economic losses.
[0034] In view of this, the present invention provides a material pump monitoring and compensation device, comprising: an inlet pipe 100 and a return pipe 200 connected to a material pump 300; the inlet pipe 100 is provided with a compensation mechanism 400, and the return pipe 200 is provided with a monitoring mechanism 500; the compensation mechanism 400 includes a compensation water tank 410 and a compensation pipeline 420, the two ends of the compensation pipeline 420 being connected to the inlet pipe 100 and the compensation water tank 410 respectively; the monitoring mechanism 500 includes an observation component and a detection component, the observation component being disposed at the end of the return pipe 200 away from the material pump 300, and the detection component being disposed in the return pipe 200, the detection component being used to detect and display the flow rate and temperature of the sealed water in the return pipe 200.
[0035] The observation component is located at the end of the return water pipe 200 furthest from the material pump 300. Operators can observe the actual water flow of the sealing water through this component, thus gaining a direct understanding of its status. The detection component is located on the return water pipe 200. Operators can use this component to monitor the flow rate and temperature of the sealing water within the return water pipe 200. If abnormalities occur in the flow rate or temperature, the machine can be stopped immediately to address the issue and prevent further damage from continued operation. When the sealing water supply pressure is too low, the compensation water tank 410 can supply its internal sealing water directly to the inlet water pipe 100 through the compensation pipeline 420, ensuring a normal supply of sealing water and enabling the material pump 300 to operate normally, thus preventing damage to the material pump 300.
[0036] In an optional embodiment, the compensation mechanism 400 further includes a pressure sensor 430 and a water pump 440. The pressure sensor 430 is disposed in the water inlet pipe 100, and the water pump 440 is used to transport water from the compensation tank 410 to the compensation pipeline 420. The pressure sensor 430 is signal-connected to the water pump 440.
[0037] Please see Figure 1 The pressure sensor 430 is located downstream of the connection point between the inlet pipe 100 and the compensation pipe 420, and can measure the supply pressure of the sealing water in the inlet pipe 100 in real time and accurately. The water pump 440 is connected to the compensation water tank 410. When the pressure sensor 430 detects that the supply pressure of the sealing water is too low, the water pump 440 receives the signal and can provide power, so that the water in the compensation water tank 410 is transported to the inlet pipe 100 through the compensation pipe 420, thereby increasing the supply pressure of the sealing water.
[0038] In an optional embodiment, the compensation mechanism 400 further includes a controller, and the pressure sensor 430 and the water pump 440 are both electrically connected to the controller.
[0039] When the pressure sensor 430 detects that the sealing water supply pressure is less than a certain value, the controller is powered on and starts. At the same time, the controller also powers on and starts the water pump 440, so that the water in the compensation tank 410 is delivered to the inlet pipe 100 through the compensation pipeline 420.
[0040] In an optional embodiment, a compensation pipeline switching valve 450 is provided on the compensation pipeline 420, and the compensation pipeline switching valve 450 is connected to the controller signal.
[0041] As an alternative, the compensation water tank 410 can store 1000 kg of soft water. After the pressure sensor 430 detects that the sealing water supply pressure is less than 1 bar for 1 minute, the controller starts. The controller controls the water pump 440 to start and opens the compensation pipeline switching valve 450 at the same time, so that the water in the compensation water tank 410 enters the inlet pipe 100 through the compensation pipeline 420 and supplies water to the material pump 300.
[0042] In an optional embodiment, the observation component includes a connecting pipe 510 and a water receiving tank 520. One end of the connecting pipe 510 is connected to the return water pipe 200, and the other end is an open end located directly above the water receiving tank 520.
[0043] Please see Figure 3 The open end of the connecting pipe 510 is directly connected to the water tank 520, allowing water from the return pipe 200 to drain downwards into the water tank 520. The water tank 520 is fixed to the frame at a height of approximately 1.6 meters, making it easily visible to operators during inspections. A small distance is left between the open end of the connecting pipe 510 and the water tank 520, allowing operators to easily monitor the actual water flow of the sealing water. Combined with data measured by the detection components, this ensures the normal circulation and supply of the sealing water.
[0044] In an optional embodiment, the water receiving tank 520 has a frustum-shaped structure with a cross-sectional area that gradually decreases from top to bottom.
[0045] Please see Figure 3 The water receiving tank 520 is designed as a truncated cone with a cross-sectional area that gradually decreases from top to bottom, which can provide a large water receiving area, prevent water from splashing outwards when the water volume is large, and allow the water to drain quickly downwards after being collected.
[0046] In an optional embodiment, the material pump monitoring and compensation device further includes a sealed water tank 600, with one end of the water inlet pipe 100 away from the material pump 300 connected to the sealed water tank 600, and the bottom of the water receiving tank 520 connected to the sealed water tank 600.
[0047] Please see Figure 2 The side wall of the sealing water tank 600 is connected to the bottom of the water receiving tank 520 through a pipeline. The sealing water flows from the sealing water tank 600 through the inlet pipe 100, the material pump 300, the return pipe 200, the connecting pipe 510 and the water receiving tank 520 and then back to the sealing water tank 600, thus completing the circulation of the sealing water.
[0048] In an optional embodiment, the detection components include a flow and temperature sensor 530 and a display screen 540. The flow and temperature sensor 530 is disposed on the return water pipe 200, and the display screen 540 is fixedly installed on the inlet water pipe 100 and the return water pipe 200. The flow and temperature sensor 530 and the display screen 540 are connected by signals.
[0049] Please see Figure 3A flow and temperature sensor 530 is located in the middle of the return water pipe 200. The sensor is connected to the return water pipe 200 via a quick connector and measures the flow rate and temperature of the sealing water within the return water pipe 200. The signal is then transmitted to the display screen 540 for display. The display screen 540 is fixedly installed on the outer wall of both the inlet pipe 100 and the return water pipe 200. The display screen 540 has a display area that can instantly display the specific flow rate and temperature values of the sealing water, allowing operators to easily check them at any time.
[0050] In an optional embodiment, the detection component further includes an audible and visual alarm light 550, which is connected to the display screen 540 via a signal line 560.
[0051] Please see Figure 3 The audible and visual alarm light 550 is electrically connected to the display screen 540 via a signal line 560. When the flow rate and temperature of the sealing water exceed the normal range, the audible and visual alarm light 550 can emit a 100-decibel alarm sound and flash light at the same time to remind the operator to pay attention and check in time.
[0052] The material pump monitoring and compensation device in this embodiment measures the flow rate and temperature of the sealing water in the return water pipe 200 using a detection component. When these values exceed the normal range, an audible and visual alarm is triggered, prompting the operator to handle the abnormality promptly. The observation component allows the operator to monitor the actual water flow status of the sealing water at any time. When the sealing water supply pressure is too low, the compensation mechanism 400 can also ensure the normal supply of sealing water.
[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
