Corrosion-resistant hydraulic electric oil pump

Corrosion-resistant hydraulic electric oil pump

The Hydraulic Pump is the power component of the Hydraulic system. It is driven by an engine or an electric motor, sucks oil from the Hydraulic Oil Tank, forms pressure oil and discharges it, and sends it to the actuator. According to the structure, hydraulic pumps are divided into gear pumps, plunger pumps, vane pumps and screw pumps.A hydraulic component that provides pressurized liquid for hydraulic transmission is a kind of pump. Its function is to convert the mechanical energy of power machines (such as electric motors and internal combustion engines) into pressure energy of liquids.The working principle of a Hydraulic pump is that movement brings about a change in the volume of the pump cavity, thereby compressing the fluid to make the fluid have pressure energy. The necessary condition is that the pump cavity has a sealed volume change.There are many factors that can affect the service life of a hydraulic pump. In addition to the pump's own design and manufacturing factors, it is also related to the selection of some components related to the use of the pump (such as couplings, oil filters, etc.), and the operation during the test run.

Types of commonly used hydraulic pumps:
1. According to whether the flow can be adjusted, it can be divided into: variable pump and fixed pump. The output flow can be adjusted according to needs is called a variable pump, and the flow cannot be adjusted is called a quantitative pump.
2. According to the commonly used pump structure in Hydraulic System, it is divided into three types: Gear Pump, Vane Pump and plunger pump.

High Pressure Hydraulic Electric Oil Pump, the same transmission shaft drives the rotors of two pumps to rotate, which are connected and driven by a motor. The suction port of the pump is public, and the pressure ports are separated. The two flows output by the pump can be used separately or in parallel.

When the cam rotates to the falling part of the curve, the spring forces the plunger downward to form a certain degree of vacuum, and the oil in the oil tank enters the sealing volume under the action of atmospheric pressure. The cam makes the plunger constantly rise and fall, the seal volume periodically decreases and increases, and the pump continuously absorbs and discharges oil.
