Description

Technical Field

[0001] This application relates to the field of emulsion pump technology, and in particular to a sealing pump cover for an emulsion pump. Background Technology

[0002] Emulsion pump sealing covers play a crucial role in underground coal mine support operations. They provide the necessary power source for hydraulic supports, ensuring the safety and efficiency of coal mine production. As a key component of hydraulic equipment, the sealing pump cover not only protects the internal components of the emulsion pump but also ensures the pump's normal operation and stability.

[0003] Pump covers are prone to generating high temperatures during use. This is mainly due to the frictional heat generated by the internal components of the pump during high-pressure and high-frequency reciprocating motion, as well as the fact that the pumped medium itself may have a high temperature.

[0004] If the pump cover temperature is too high, it will not only accelerate the aging and wear of the seals, but may also cause the performance of the pump cover material to deteriorate, affecting the overall sealing performance and service life of the pump. Utility Model Content

[0005] To facilitate cooling of the sealing elements of the pump cover, this application provides a sealing pump cover for an emulsion pump.

[0016] Optionally, two sealing rings are provided between the end cap and the cooling cap, and the cooling pipe is placed between the two sealing rings.

[0017] Optionally, the cooling pipe is arranged in a vortex shape, with the liquid inlet of the cooling pipe located near the side of the end cap and the liquid outlet of the cooling pipe located near the axis of the end cap.

[0018] Optionally, the cooling pipe is provided with a plurality of fixing blocks for fixing the cooling pipe.

[0019] Optionally, the cooling channel is provided with a limiting groove for the insertion and engagement of the fixing block.

[0023] 1.

[0029] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0030] This application discloses a sealing pump cover for an emulsion pump.

[0031] A sealing pump cover for an emulsion pump includes an end cover 1, a cooling cover 2, a cooling pipe 3, an inlet pipe 4, an outlet pipe 5, a temperature detection unit 6, a control valve 7, and a flow detection unit 8.

[0032] End cap 1 is installed on the housing 9 of the emulsion pump. Its shape and size match the pump housing 9 to ensure a sealed and stable installation. End cap 1 is made of high-strength cast iron or stainless steel to withstand the pressure inside the pump.

[0033] The cooling cap 2 is sealed and detachably mounted on the end cap 1. A cooling channel 11 is provided between the cooling cap 2 and the end cap 1, which is used to circulate coolant to control the temperature of the pump cap. The cooling cap 2 is provided with a pipe for discharging emulsion, which communicates with the interior of the emulsion pump housing 9.

[0034] Two sealing rings 12 are provided between the end cap 1 and the cooling cap 2, and the cooling pipe 3 is placed between these two sealing rings 12 to ensure the sealing of the cooling channel 11 and reduce the possibility of coolant mixing into the emulsion.

[0035] A connecting ring 21 is coaxially provided on the outer circumferential surface of the cooling cover 2. The connecting ring 21 is threadedly connected to the outer circumferential surface of the end cover 1 to ensure stable installation of the cooling cover 2. When installing the cooling cover 2, the connecting ring 21 and the end cover 1 are threadedly connected to improve the ease of connection between the cooling cover 2 and the end cover 1. At the same time, when the connecting ring 21 and the end cover 1 are threadedly connected, the end cover 1 and the cooling cover 2 gradually compress the sealing ring 12, improving the ease of installation and operational stability of the sealing ring 12.

[0036] Cooling pipe 3 is installed inside cooling channel 11, through which coolant flows. The inlet and outlet of cooling pipe 3 are located on the side and near the axis of end cap 1, respectively, to optimize cooling effect.

[0037] Because the temperature difference between the liquid inlet end of the cooling pipe 3 and the side wall of the end cover 1 is large, it is easier to cool down the sealing element on the side wall of the end cover 1 and improve the cooling effect on the sealing element of the end cover 1.

[0038] Meanwhile, the cooling pipe 3 is installed inside the cooling channel 11. When the cooling channel 11 needs to be cleaned, the cooling pipe 3 can be replaced directly, which improves the convenience of cleaning the cooling channel 11.

[0039] The cooling pipe 3 is provided with several fixing blocks 31 to fix the position of the cooling pipe 3, which reduces the structural stability of the cooling pipe 3 during storage and handling, and reduces the possibility of deformation of the cooling pipe 3. The cooling channel 11 is provided with a limiting groove 13 that cooperates with the fixing blocks 31. When the cooling pipe 3 is placed inside the cooling channel 11, the fixing blocks 31 are placed in the limiting groove 13, thereby ensuring the stable fixation of the cooling pipe 3 and the accuracy of its placement position.

[0040] Temperature detection unit 6 is mounted on cooling cap 2 and is used to measure the temperature of the coolant in cooling pipe 3. Multiple temperature detection units 6 can be arranged along the diameter of cooling cap 2 to ensure comprehensive temperature monitoring.

[0041] Control valve 7 is installed on inlet pipe 4 and outlet pipe 5 and is electrically connected to temperature detection unit 6. Control valve 7 automatically adjusts according to the signal from temperature detection unit 6 to control the flow rate of coolant, thereby maintaining a suitable temperature for the pump cover.

[0042] The temperature detection unit 6 detects the temperature signal of the coolant in the cooling pipe 3 and transmits the temperature signal to the control valve 7. When the coolant temperature exceeds the set value, the control valve 7 opens the inlet pipe 4 and the storage pipe passage, allowing the coolant to flow into the cooling pipe 3 for cooling and discharging the original cold liquid inside the cooling pipe 3. At the same time, the control valve 7 on the inlet pipe 4 and the outlet pipe 5 is closed to reduce the possibility of the excessively hot coolant affecting the temperature of the coolant inside the cooling pipe 3.

[0043] Both the inlet pipe 4 and the outlet pipe 5 are equipped with flow detection units 8 to monitor the flow rate of the coolant, ensuring the efficiency and stability of the cooling system. When the flow rate of the coolant inside the inlet pipe 4 and the outlet pipe 5 is lower than the set value, it is convenient to remove the end cap 1 and the cooling cap 2 in a timely manner to replace the cooling pipe 3.

[0044] The implementation principle of a sealing pump cover for an emulsion pump according to an embodiment of this application is as follows: Coolant enters the cooling pipe 3 through the inlet pipe 4, flows along the vortex-shaped cooling pipe 3, passes through the cooling channel 11 between the end cap 1 and the cooling cover 2, carrying away the heat generated by the pump cover, and then exits from the outlet pipe 5. The temperature detection unit 6 monitors the temperature of the coolant in the cooling pipe 3 in real time and transmits the data to the control valve 7. The control valve 7 automatically adjusts the opening and closing of the inlet pipe 4 and the outlet pipe 5 according to the received temperature signal to control the flow rate of the coolant, thereby maintaining a suitable temperature for the pump cover and reducing coolant loss. Simultaneously, the flow detection unit 8 monitors the flow rate of the coolant to ensure the efficiency and stability of the cooling system.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
