Hydraulic system

W Arnold

1 Introduction

The hydraulic station is called a hydraulic pump station and is an

independent hydraulic device. It is step by step to supply oil. And control

the direction of hydraulic oil flow, pressure and flow, suitable for the host

and hydraulic equipment can be separated on the various hydraulic

machinery.

After the purchase, the user only needs to connect the hydraulic station

and the actuator (hydraulic or oil motor) on the mainframe with different

tubings. The hydraulic machine can realize various specified actions and

working cycles.

The hydraulic station is a combination of manifolds, pump units or valve

assemblies, electrical boxes, and tank electrical boxes. Each part function

is:

The pump unit is equipped with a motor and an oil pump, which is the

power source of the hydraulic station and can convert mechanical energy

into hydraulic oil pressure energy.

Valve combination - its plate valve is mounted on the vertical plate, and

the rear plate is connected with the same function as the manifold.

Oil manifolds - assembled from hydraulic valves and channel bodies. It

regulates hydraulic oil pressure, direction and flow.

Box--a semi-closed container for plate welding. It is also equipped with

an oil screen, an air filter, etc., which is used for cooling and filtering of

oil and oil.

Electrical box - divided into two types: one is to set the external lead

terminal board; one is equipped with a full set of control appliances.

The working principle of the hydraulic station: The motor drives the oil

pump to rotate, then the pump sucks oil from the oil tank and supplies oil,

converts the mechanical energy into hydraulic pressure energy, and the

hydraulic oil passes through the manifold (or valve assembly) to adjust

the direction, pressure and flow and then passes through the external tube.

The way to the hydraulic cylinder or oil motor in the hydraulic machinery,

so as to control the direction of the hydraulic motor, the strength of the

speed and speed, to promote all kinds of hydraulic machinery to do work.

(1) Development history of hydraulic pressure

The development history of hydraulics (including hydraulic power, the

same below), pneumatics, and seals industry in China can be roughly

divided into three stages, namely: the starting stage in the early 1950s to

the early 60s; and the professional in the 60s and 70s. The growth stage of

the production system; the 80-90's is a stage of rapid development.

Among them, the hydraulic industry began in the early 1950s with the
