Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic equipment, in particular to a hydraulic station for crawler mobile crushing and screening equipment. Background Art

[0002] The hydraulic station is also called a hydraulic pump station. The oil pump is driven by an electric motor. The oil pump draws oil from the oil tank and then pumps it, thereby converting mechanical energy into the pressure energy of the hydraulic oil. The hydraulic oil is adjusted in direction, pressure and flow through an integrated block (or valve combination) and then transmitted to the oil cylinder or oil motor of the hydraulic machinery through an external pipeline, thereby controlling the change of direction, force and speed of the hydraulic motor and driving various hydraulic machinery to do work.

[0003] The hydraulic system of the crushing and screening equipment is usually integrated with the engine in a power box assembly. In order to integrate them together, the space required inside the power box will be very large. If the space inside the power box is compact or insufficient, it will affect the use and maintenance of the engine and hydraulic components. Not only will it be difficult to maintain, but it will also cause high temperature effects on the hydraulic system. Since the engine in the power box generates heat, the heat dissipation in the box is insufficient, which will affect the temperature of the hydraulic oil tank. For example, a crawler-type impact mobile crushing and screening station disclosed in application number 202011593530.3, in which the power system mainly includes an engine, a generator and a hydraulic pump; the hydraulic power system is installed in the engine power box. Since the engine in the power box generates heat, the heat dissipation in the box is insufficient, which will affect the temperature of the hydraulic oil tank, but the generator and the motor are relatively large as a whole and require a certain space. During operation, if the heat dissipation of the power box assembly is poor, high temperature effects will be generated, resulting in protection shutdown and reduced service life of pipeline line components. Insufficient space and difficult maintenance will increase maintenance costs. Therefore, it is urgent to propose a hydraulic station for crawler mobile crushing and screening equipment to solve the above-mentioned problems. Utility Model Content

Compared with the traditional method of installing the entire hydraulic power system in the engine power box, it is changed to an integrated modular setting and can be installed independently outside the power box, which solves the problem that the engine in the power box generates heat and the heat dissipation in the box is insufficient, which affects the temperature of the hydraulic oil tank. It can improve the convenience of application and maintenance and prevent the hydraulic components and hydraulic oil from being affected by high temperature. BRIEF DESCRIPTION OF THE DRAWINGS
