Description

Technical Field

[0001] This utility model relates to the field of hydraulic pump station technology, and more specifically, to a hydraulic wrench pump station. Background Technology

[0002] A hydraulic pump station is a hydraulic device used to provide hydraulic pressure to hydraulically controlled components, such as a hydraulic pump station used to drive a hydraulic wrench. Currently, Chinese Patent Publication No. CN221779592U discloses a manual hydraulic wrench pump. In this prior art, although the manual hydraulic wrench pump is equipped with a cooler for cooling the hydraulic oil, the cooler needs to rely on an independent fan for air cooling, which results in the disadvantages of complex structure and high energy consumption. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a hydraulic wrench pump station, in which the motor inside drives the hydraulic pump body assembly to operate, and the air discharged by the motor can achieve the air cooling effect on the plate heat exchanger, so as to simplify the structure, reduce the cost of parts and reduce energy consumption.

[0004] This utility model provides a hydraulic wrench pump station, including an oil tank, a support plate, a motor, a hydraulic pump body assembly, and a hydraulic valve block assembly. The support plate is sealed and fixed to the opening at the upper end of the oil tank. The motor and the hydraulic valve block assembly are both fixed to the upper end of the support plate. The hydraulic pump body assembly is located inside the oil tank and fixed to the lower end of the support plate. The hydraulic pump body assembly is driven by the output shaft of the motor. The hydraulic valve block assembly is connected to the hydraulic pump body assembly through a connecting pipe. The hydraulic wrench pump station also includes a plate heat exchanger, an oil inlet pipe assembly, and an oil outlet pipe assembly. One end of the component passes through the support plate and extends into the oil tank. One end of the oil inlet pipe assembly is immersed in the hydraulic oil inside the oil tank, and the other end of the oil inlet pipe assembly is connected to the oil inlet connector of the plate heat exchanger. One end of the oil outlet pipe assembly passes through the support plate and extends into the oil tank, and is connected to the oil inlet of the hydraulic pump body assembly. The other end of the oil outlet pipe assembly is connected to the oil outlet connector of the plate heat exchanger. The plate heat exchanger is located above the tail end of the motor and is spaced apart from the motor. The plate heat exchanger faces the air outlet on the tail end of the motor and is fixed to the motor.

[0005] By adopting this structure, when the motor rotates and drives the hydraulic pump assembly, the fan blades inside the motor rotate synchronously. At this time, the air drawn in from the front of the motor can be discharged through the air outlet at the rear of the motor. The air discharged from the rear of the motor can blow onto the plate heat exchanger, thereby improving the cooling efficiency and effect of the plate heat exchanger on the hydraulic oil. That is, during the process of the motor driving the hydraulic pump assembly to make the hydraulic oil flow sequentially through the inlet pipe assembly, plate heat exchanger, outlet pipe assembly, hydraulic pump assembly and connecting pipe to the hydraulic valve block assembly, the plate heat exchanger can cool the hydraulic oil, and the air blown onto the plate heat exchanger by the rear of the motor can improve the heat dissipation efficiency and effect of the plate heat exchanger on the hydraulic oil. In other words, while the motor drives the hydraulic pump assembly, the air discharged by the motor can achieve the air cooling effect on the plate heat exchanger, thereby eliminating the need for the original fan installed on the plate heat exchanger, so as to simplify the structure, reduce the cost of components and reduce energy consumption.

[0006] In one possible implementation, the hydraulic wrench pump station also includes two columns and two "L"-shaped connectors; the lower ends of the two columns are fixed to the outer wall of the motor, and one end of each connector is fixed to the upper end of one of the columns. The oil inlet and outlet connectors are respectively inserted into the other end of one connector and fastened to the connector. With this structure, the plate heat exchanger can be reliably supported by the cooperation of the columns and connectors, that is, the plate heat exchanger can be reliably fixed to the motor. In addition, the connectors can be fastened to the upper end of the columns by nut assemblies.

[0007] In one possible implementation, the outer wall of the motor is provided with lugs corresponding to each column, and the lower ends of the two columns are respectively inserted into one of the lugs and fastened to the lug; with this structure, the lower ends of the columns can be reliably fixed to the outer wall of the motor, and the lower ends of the columns can be fastened to the lugs by a nut assembly.

[0008] In one possible implementation, the oil inlet pipe assembly includes a first oil inlet pipe, a first connector, and a second oil inlet pipe. The first connector is inserted into the support plate, and is fastened to the support plate and circumferentially sealed. One end of the first oil inlet pipe is immersed in hydraulic oil located inside the oil tank, and the other end of the first oil inlet pipe is connected to the lower end of the first connector. The two ends of the second oil inlet pipe are respectively connected to the upper end of the first connector and the oil inlet connector. With this structure, since the first connector is fastened to the support plate and circumferentially sealed, the oil inlet pipe assembly can be reliably fastened to the support plate and achieve circumferential sealing with the support plate.

[0009] In one possible implementation, the oil outlet pipe assembly includes a first oil outlet pipe, a second connector, and a second oil outlet pipe. The second connector is inserted into the support plate and is fastened to the support plate and circumferentially sealed. The two ends of the first oil outlet pipe are respectively connected to the oil outlet connector and the upper end of the second connector. The second oil outlet pipe is respectively connected to the lower end of the second connector and the oil inlet of the hydraulic pump body assembly. With this structure, since the second connector is fastened to the support plate and circumferentially sealed, the oil outlet pipe assembly can be reliably fastened to the support plate and achieve circumferential sealing with the support plate.

[0010] In one possible implementation, two pressure sensors are connected to the hydraulic valve block assembly. The detection ends of the two pressure sensors are respectively connected to the oil supply channel and the oil return channel in the hydraulic valve block assembly. Both pressure sensors are electrically connected to the controller in the hydraulic wrench pump station. By setting up two pressure sensors, the two pressure sensors can monitor the oil pressure in the oil supply channel and the oil pressure in the oil return channel of the hydraulic valve block assembly, thereby facilitating the controller to dynamically control the working status and speed of the motor.
