The hydraulic pump is the power component of the hydraulic system. It is driven by the internal combustion engine or electric motor, sucks oil from the hydraulic oil tank, forms pressure oil, conveys it and passes it on to the actuator. hydraulic pumps are divided into gear pumps, plunger pumps, vane pumps and screw pumps according to their design.

What is the efficiency parameter of the hydraulic pump?
The hydraulic pump is a hydraulic component that provides pressurized fluid for hydraulic transmission, and is a kind of pump. Its function is to convert the mechanical energy of the power machine (e.g., electric motor and combustion engine, etc.) into the pressure energy of the liquid. There are many factors that affect the service life of hydraulic pumps. In addition to the design and manufacturing factors of the pump itself, this is also related to the selection of some components related to the use of the pump (such as couplings, oil filters, etc.) and operation during the test run.
The working principle of a hydraulic pump is that a movement causes a volume change of the pump chamber, whereby the fluid is compressed so that the fluid has pressure energy.
The necessary condition is that the pump chamber has a sealed volume change.
There are three main types of hydraulic pumps: gear, vane and piston pumps.
Gear pumps: Gear pumps are the most common type of hydraulic pumps. They use rotating gears to move fluid through the pump. Gear pumps are typically used in low pressure applications.
Wing cell pumps: Wing cell pumps use a series of wings to move liquid through the pump. Wing cell pumps are typically used in high pressure applications.
Piston pumps: Piston pumps use a series of pistons to move liquid through the pump. Piston pumps are typically used in high pressure applications.
There are a few things to consider when choosing the right hydraulic pump for your application. The first is what pressure you need. hydraulic pumps are available in a variety of pressures, from low to high. You should also consider the flow rate. That much liquid can move the pump per minute. Another thing to think about is the power source. hydraulic pumps can be powered by electricity, gas or diesel. Finally, you should make sure that the pump is compatible with the rest of your equipment.
The volumetric efficiency of a hydraulic pump refers to the ratio of its actual flow to its theoretical flow. For hydraulic motors, it refers to the ratio of theoretical flow to actual flow.
The mechanical efficiency of a hydraulic pump refers to the ratio of its theoretical torque to the actual input torque. The actual output torque of the hydraulic motor is the torque after the theoretical torque has overcome the frictional force, so its mechanical efficiency is the ratio of the actual output torque to the theoretical torque.
Total efficiency refers to the ratio of the output power of the pump (or motor) to the input power. The total efficiency is equal to the product of volumetric efficiency and mechanical efficiency.
