How to classify hydraulic pump stations?

A hydraulic pump station, also known as a hydraulic station, operates as follows: a motor drives an oil pump, which draws oil from the pump and pumps it, converting mechanical energy into the pressure energy of hydraulic oil. The hydraulic oil passes through a manifold (or valve assembly), where its direction, pressure, and flow are regulated by hydraulic valves. The oil is then transferred through external pipelines to the hydraulic cylinder or motor of the hydraulic machinery, thereby controlling the direction, force, and speed of the hydraulic motor, thereby driving various hydraulic machines to perform work.

Classification of Hydraulic Pump Stations

(I) Drive Type

Electric Type: This type of hydraulic pump station uses an electric motor as the prime mover and is suitable for stationary machinery with a stable power supply. It produces low noise during operation and is therefore the most commonly used.

Mobile Type: This type of hydraulic pump station uses a diesel or gasoline engine as the prime mover and does not require a power source. It is convenient for use in remote areas without power or with insufficient electrical circuits, as well as for various types of construction equipment used in field operations. However, it is noisy during operation and has a low usage rate.

Manual Type: This type of hydraulic pump station is primarily manually operated and can be considered a hand pump. Although its efficiency is relatively low, it can supply oil to small-stroke hydraulic cylinders through simple piping. Therefore, it is often used with manual machines and equipment such as small presses, testing machines, pipe benders, emergency rescue demolition equipment, and hydraulic shears. It can also serve as a portable power source for motor vehicles.

(II) Output Pressure and Flow Characteristics

Hydraulic pump stations can be categorized by output pressure: low pressure, medium pressure, medium-high pressure, high pressure, and ultra-high pressure. The pressure values are as follows:

Low-pressure pump stations have output pressures of ≤2.5 MPa;

Medium-pressure pump stations have output pressures greater than 2.5 to 8 MPa;

Medium-high pressure pump stations have output pressures greater than 8 to 16 MPa;

High-pressure pump stations have output pressures greater than 16 to 32 MPa;

Ultra-high pressure pump stations have output pressures greater than 32 MPa.

For example, this 80 MPa high-pressure electric hydraulic pump station is equipped with a Honda GX160 gasoline engine, providing maximum power to the hydraulic compressor or any other related equipment, ensuring the highest performance standards.
