The hydraulic pump station, also known as the hydraulic station, is an independent hydraulic equipment. It supplies oil according to the requirements of the driving equipment (main machine), and controls the direction, pressure and flow of the fluid flow. It is applicable to various hydraulic machinery that can be separated from the main machine and hydraulic equipment.

1. Composition of hydraulic pump station

The hydraulic pump station is composed of pump equipment, manifold block or valve combination, oil tank, electrical box, etc. The functions of each component are as follows.

(1) Pump equipment: motor and oil pump are installed on it. It is the power source of the hydraulic station, which converts the mechanical energy into the pressure energy of the hydraulic oil.

(2) Valve assembly: the plate valve is installed on the vertical plate and connected with the pipe behind the plate, which has the same function as the manifold block.

(3) Integrated block: composed of hydraulic valve and channel body. It regulates the direction, pressure and flow of hydraulic oil.

(4) The electrical box has two forms: one is a terminal board with external leads; One is equipped with a full set of control appliances.

(5) Oil tank: semi closed container welded by steel plate, with oil filter screen and air filter installed on it, which is used to store oil, cool and filter oil.

The operating principle of the hydraulic pump station is as follows: the motor drives the hydraulic pump to rotate, and the hydraulic pump converts the rotating mechanical energy into the pressure energy of the hydraulic oil. After the hydraulic oil has completed the adjustment of direction, pressure and flow through the manifold block (or valve combination), it is transmitted to the hydraulic cylinder or hydraulic motor of the main engine through the external hydraulic pipeline, so as to control the direction change of the main engine, the size and speed of the force, and promote various hydraulic machinery to do work.

2. Application and protection of hydraulic pump station

(1) Operating conditions. The ambient temperature scale is - 20~80 ℃, and the high temperature Z of continuous operation should not exceed 60 ℃. The oil temperature should be checked frequently during operation, and the liquid level thermometer should be touched and checked. If the oil temperature rises abnormally, it may be caused by the following conditions:

① Oil quality deteriorates and resistance increases:

② The oil tank has small volume, slow heat emission and no cooling equipment;

③ The dust and dirt inside the element are blocked, and the pressure loss is too large.

(2) The hydraulic oil in the oil tank shall be kept at a normal level. The oil tank shall be cleaned frequently. The oil shall be injected from the oil filler of the air filter. After the hydraulic station has been in operation for a month, the oil tank shall be cleaned and the hydraulic oil replaced. After half a year of operation, the hydraulic oil shall be replaced again. In the future, the hydraulic oil shall be replaced once a year.

(3) The pump oil suction filter and pressure oil filter shall be cleaned regularly according to the operation condition. If they are blocked, the pump may be polluted and damaged.

(4) If a hydraulic part is damaged, it can be replaced at any time. When replacing the hydraulic valve, pay attention to different slide valve functions, and do not make mistakes.

(5) When the system fails, it is prohibited to check in the operation state.
