Description

Technical Field

[0001] This utility model relates to a hydraulic pump station. Background Technology

[0002] In hydraulic pump stations, the piping of the hydraulic system is typically installed on the outer surface of the oil tank or in the surrounding environment. When space is limited, the oil pump motor unit is often placed at the bottom of the hydraulic oil tank. In this case, the oil outlet pipe of the pump is often still installed from the outside or surrounding area of ​​the tank. This increases the overall size of the hydraulic pump station, and during transportation and handling, the exposed pipes are frequently subjected to external impacts. Such impacts can lead to pipe deformation or leaks, complicating the design and use of hydraulic pump stations. Therefore, existing hydraulic pump stations have limitations and require improvement. Summary of the Invention

[0003] The purpose of this utility model is to design a hydraulic pump station.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a hydraulic pump station, including: a base frame 1, an oil suction filter 2, an oil pump motor unit 3, an oil tank 4, an oil return filter 5, a valve group 6, an oil pump outlet pipe 7, and an oil tank through pipe 401. The feature is that: an oil tank through pipe 401 is provided on the oil tank 4, the oil tank through pipe 401 is fixedly welded to the oil tank 4, and the oil pump outlet crimping pipe 7 passes through the inner hole of the oil tank through pipe 401 and is connected to the valve group 6.

[0005] The beneficial effects of this utility model are that it allows hydraulic oil pipes to pass through the oil tank very easily, realizing the connection between hydraulic components, limiting the increase in the size of the hydraulic pump station, making the hydraulic pump station smaller and more compact, meeting the needs of space constraints, and ensuring that the pipelines are not damaged during handling and transportation, and that the normal operation of the pump station is not affected.

[0011] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of this utility model, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this utility model.

[0012] The instruction manual includes Figure 1 and the instruction manual Figure 2 As shown: the oil tank 4 is fixed on the base frame 1, the oil suction filter 3 is connected to the bottom of the oil tank, and is connected to the oil pump motor unit 3 through a pipe.

[0013] The instruction manual includes Figure 1 and the instruction manual Figure 2 As shown: The return oil filter 5 is connected to the top of the oil tank and is connected to the valve assembly 6 through a pipe.

[0014] The instruction manual includes Figure 1 and the instruction manual Figure 2 As shown: the oil pump outlet pipe 7 passes through the inner hole of the oil tank through pipe on the oil tank 4, connecting the oil pump motor unit 3 to the oil inlet of the valve group 6.

[0015] The instruction manual includes Figure 3 As shown: The oil tank 4 is provided with an oil tank through pipe 401. The oil tank through pipe 401 passes through both ends of the oil tank and is fixedly welded to the upper top plate and the lower bottom plate. There is no leakage. The oil pump outlet crimping pipe 7 can easily pass through the oil tank through pipe 401 to connect the oil pump motor unit 3 and the valve group 6.

[0016] A hydraulic pump station operates as follows: After hydraulic oil is filled to the specified level in the oil tank 4, the oil pump motor unit 3 is started. The hydraulic oil is delivered to the oil pump motor unit 3 through the suction filter. The oil pump motor unit 3 then delivers the pressurized hydraulic oil to the valve group 6 through the oil pump outlet pressure pipe 7. By controlling the action of the valve group 6, the hydraulic oil is transmitted to the working machine, realizing the hydraulic transmission function of the hydraulic pump station. This hydraulic pump station is rationally designed, compact in structure, and easy to operate.
