Description

Technical Field

[0001] This utility model relates to a high-pressure pump system, and more specifically, to a high-pressure pump system with a blockage self-check function. Background Technology

[0002] High-pressure pump systems are primarily used in the machining industry to deliver cutting fluid to the machine tool during milling. For example, Chinese patent document CN218746514U, entitled "Tank-Type High-Pressure Pump System," discloses a high-pressure pump system that uses a high-pressure pump to deliver cutting fluid from a tank to the machine tool via pipelines. This system also has a water replenishment function, using a level gauge to detect the tank level. When the level falls below a set point, a replenishment pump is activated to deliver external cutting fluid to the tank. The replenishment pump also features a secondary filter tank at its inlet to filter impurities from the cutting fluid. In practical use, to prevent clogging due to excessive impurities, the filter element of the secondary filter tank needs to be inspected and replaced periodically or irregularly, depending on the actual machining conditions, making it relatively cumbersome. Utility Model Content

[0003] To address the shortcomings of the existing technology, this invention provides a high-pressure pump system that can detect blockages and issue an alarm during liquid replenishment.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A high-pressure pump system with self-detection of blockage includes a high-pressure pump body with a replenishment component. The replenishment component includes a replenishment pump and a filter tank connected to the replenishment pump via a pipe. The high-pressure pump body also includes a control circuit board, an alarm, and a negative pressure sensor. The negative pressure sensor is located on the pipe between the replenishment pump and the filter tank and is used to detect the negative pressure value of the liquid in the pipe. The negative pressure sensor and the alarm are electrically connected to the control circuit board. When the negative pressure value is lower than a set value, the control circuit board controls the alarm to issue an alarm signal.

[0006] Furthermore, the high-pressure pump body includes an instrument panel, on which a negative pressure gauge is provided for displaying the negative pressure value detected by the negative pressure sensor.

[0007] Furthermore, the high-pressure pump body includes a high-pressure pump assembly and a liquid storage tank. The high-pressure pump assembly, the liquid replenishment assembly, and the instrument panel are all fixedly connected to the top of the liquid storage tank. The high-pressure pump assembly is close to the front end of the liquid storage tank, the liquid replenishment assembly is located behind and adjacent to the high-pressure pump assembly, and the instrument panel is located above the high-pressure pump assembly.

[0008] Furthermore, the replenishment assembly includes a mounting plate vertically installed at the top of the storage tank, and the replenishment pump is fixedly connected to the vertical wall of the mounting plate with its head facing downwards.

[0009] Furthermore, it also includes a circulating chiller for cooling the coolant in the water storage tank, the circulating chiller being fixedly connected to the top of the water storage tank and adjacent to the liquid replenishment assembly.

[0010] Furthermore, the high-pressure pump assembly includes a high-pressure pump, a multi-channel oil block, and at least one connector. The inlet of the multi-channel oil block is connected to the outlet of the high-pressure pump. The multi-channel oil block includes multiple outlets that can be opened and closed individually. The connector is detachably threaded to the outlet.

[0011] Furthermore, the liquid storage tank is also equipped with a liquid level gauge, which is electrically connected to the control circuit board and is used to control the replenishment pump to start replenishment operation when the liquid level in the storage tank is lower than the set value.

[0012] Furthermore, the high-pressure pump assembly includes a high-pressure pump and a filter cartridge. The high-pressure pump has an inlet pipe extending below the liquid level in the storage tank, and the filter cartridge is fixedly connected to the opening of the inlet pipe.

[0013] Furthermore, the filter element inside the filter canister is a reusable filter element.

[0014] In summary, the beneficial effects of this utility model are as follows: A negative pressure sensor is installed on the pipeline between the replenishment pump and the filter tank. The negative pressure sensor and the alarm are connected to the control circuit board. During use, the negative pressure sensor detects the negative pressure data of the pipeline between the replenishment pump and the filter tank in real time and transmits this data to the control circuit board. When the negative pressure value is lower than the set value, it indicates that there is a blockage in the filter tank, causing the negative pressure value in the pipeline to decrease. At this time, the control circuit board controls the alarm to issue an alarm signal, notifying the operator to handle the blockage problem. Attached Figure Description

[0019] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and 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. Therefore, they should not be construed as limitations on this utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0023] Reference Figure 1 and Figure 2 A high-pressure pump system with blockage self-detection includes a high-pressure pump body with a replenishment component 1. The replenishment component 1 includes a replenishment pump 11 and a filter tank 12 connected to the replenishment pump 11 via a pipe. The high-pressure pump body also includes a control circuit board 2, an alarm, and a negative pressure sensor 3. The negative pressure sensor 3 is located on the pipe between the replenishment pump 11 and the filter tank 12 and is used to detect the negative pressure value of the liquid in the pipe. The negative pressure sensor 3 and the alarm are electrically connected to the control circuit board 2 respectively.

[0024] When the filter tank 12 becomes clogged, the resistance to the flow of cutting fluid through it increases, causing a decrease in pressure within the pipe between the replenishment pump 11 and the filter tank 12. The negative pressure sensor 3 detects the negative pressure data at a certain frequency and sends it to the control circuit board 2. The control circuit board 2 compares this data with a preset negative pressure value. If the pressure is lower than the set value, the control circuit board 2 activates an alarm signal. The alarm can be an audible alarm, an optical alarm, or a combination of both, to notify relevant operators through sound, light, or a combination of both.

[0025] Preferably, the filter element inside the filter canister 12 is a reusable filter element. The filter canister 12 is a hollow cylinder with a removable threaded end cap at the top, and the filter element is placed inside the filter canister 12. The filter element can be removed for cleaning by unscrewing the end cap, reducing clogging. After repeated use, it is necessary to replace the filter element with a new one if necessary.

[0026] In one embodiment, reference is made to Figure 1 The high-pressure pump body includes an instrument panel 4, on which a negative pressure gauge is provided to display the negative pressure value detected by the negative pressure sensor 3. The negative pressure gauge facilitates the operator's observation of the negative pressure in the pipeline between the replenishment pump 11 and the filter tank 12. Additionally, a positive pressure sensor 6 can be installed at the outlet of the high-pressure pump assembly 7, and a positive pressure gauge 5 can also be installed on the instrument panel 4 to display the positive pressure value at the outlet of the high-pressure pump assembly 7.

[0027] In one embodiment, reference is made to Figure 1 and Figure 2 The high-pressure pump body includes a high-pressure pump assembly 7 and a liquid reservoir 8. The high-pressure pump assembly 7, the liquid replenishment assembly 1, and the instrument panel 4 are all fixedly connected to the top of the liquid reservoir 8. The high-pressure pump assembly 7 is located near the front end of the liquid reservoir 8, the liquid replenishment assembly 1 is located behind and adjacent to the high-pressure pump assembly 7, and the instrument panel 4 is located above the high-pressure pump assembly 7. In addition, a circulating cooler 9 is fixedly connected to the top of the liquid reservoir 8, adjacent to the liquid replenishment assembly 1. The circulating cooler 9 is used to cool the cutting fluid in the liquid reservoir. When the cutting fluid flows through the machining area of ​​the workpiece on the machine tool, it carries away the heat generated during machining, causing the cutting fluid temperature to rise. Therefore, the circulating cooler 9 is set up to cool the cutting fluid and maintain its temperature within a suitable range to maintain the good performance of the cutting fluid.

[0028] In one embodiment, reference is made to Figure 1 and Figure 2The replenishment assembly 1 includes a mounting plate 13 vertically installed at the top of the storage tank 8, and the replenishment pump 11 is fixedly connected to the vertical wall of the mounting plate 13 with its head facing downwards. Arranging the replenishment pump 11 vertically reduces the horizontal space occupied, allowing for a more compact arrangement of the entire high-pressure pump system. Preferably, the storage tank 8 is also equipped with a level gauge 81, which is electrically connected to the control circuit board 2. When the liquid level in the storage tank is lower than a set value, the control circuit board 2 controls the replenishment pump 11 to start replenishment, achieving automatic replenishment without manual operation and improving efficiency.

[0029] like Figure 1 As shown, the high-pressure pump assembly 7 includes a high-pressure pump 71 and a filter cartridge 72. The high-pressure pump 71 has an inlet pipe extending below the liquid level in the storage tank 8. The filter cartridge 72 is fixedly connected to the opening of the inlet pipe. By setting the filter cartridge 72, the cutting fluid entering the high-pressure pump 71 from the storage tank 8 is further purified, ensuring the clean recycling of the cutting fluid.

[0030] In one embodiment, reference is made to Figure 2 The high-pressure pump assembly 7 includes a high-pressure pump 71, at least one connector 73, and a multi-channel oil block 74. The inlet of the multi-channel oil block 74 is connected to the outlet of the high-pressure pump 71. The multi-channel oil block 74 has multiple outlets, each equipped with a solenoid valve, which controls its individual opening and closing. The connector 73 is detachably threaded to the outlet. In practical use, some machine tools have only one cutting tool and only need one cutting fluid supply; other machine tools have multiple cutting tools and require multiple cutting fluid supply channels. By setting up the multi-channel oil block 74 and allowing each outlet to be individually controlled, single-channel or multi-channel fluid supply can be achieved to meet the fluid supply needs of different machine tools.

[0031] Depending on the actual situation, the instrument panel 4 can be equipped with a voltage indicator light 10, a running indicator light 20, and an alarm light 30. The high-pressure pump body has a signal aviation socket 40, a power aviation socket 50, and a rotary switch 60 on its side wall. To prevent the liquid level in the storage tank 8 from being abnormally filled, an overflow port 82 is also provided on the storage tank 8. In addition, casters are provided at the bottom of the storage tank 8 to facilitate the movement of the entire unit.

[0032] The above embodiments are merely explanations of the present utility model and are not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to the embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.
