Mechanical Hydraulic Pump Station

The mechanical hydraulic pump station is the core component of the hydraulic system. Its main function is to convert mechanical energy into hydraulic energy and provide a power source for hydraulic equipment (such as hydraulic cylinders, hydraulic motors, etc.). The hydraulic pump station works together through hydraulic pumps, oil tanks, control valves, filters and other components to generate high-pressure hydraulic oil and deliver it to hydraulic actuators to complete mechanical transmission, control and other tasks.

Main Components
Hydraulic pump: The hydraulic pump is the heart of the hydraulic pump station, which is used to convert mechanical energy into hydraulic energy and promote the flow of oil in the hydraulic system. Common types of hydraulic pumps include gear pumps, vane pumps, plunger pumps, etc.
Motor: Usually an electric motor is used as a power source to drive a hydraulic pump to provide the power required by the hydraulic system.
Oil tank: The oil tank is used to store hydraulic oil, keep the oil clean and provide an appropriate oil level. The design of the oil tank also plays a role in heat dissipation, filtration and degassing.
Valve group: The hydraulic pump station is equipped with various valves (such as overflow valves, directional control valves, pressure control valves, etc.) to adjust the direction, flow and pressure of the oil flow to ensure the smooth operation of the hydraulic system.
Filter: The filter is used to clean the hydraulic oil, remove impurities, particles and moisture in the oil, and avoid damaging the components of the hydraulic system.
Cooling system: High-power hydraulic pump stations are often equipped with cooling devices (such as air cooling or water cooling systems) to prevent the hydraulic oil from overheating due to long-term operation, thereby affecting the performance and service life of the system.
Pressure gauge and flow meter: used to monitor the pressure and flow of the hydraulic system in real time to ensure that the hydraulic pump station operates under the specified working conditions.

Working Principle
The hydraulic pump station drives the hydraulic pump through an electric motor to extract and pressurize the hydraulic oil in the oil tank, and controls the direction, flow and pressure of the oil flow through the valve group, and finally sends the hydraulic oil to the hydraulic actuator (such as hydraulic cylinder, hydraulic motor, etc.) to drive mechanical movement. Through different valve group controls, the hydraulic pump station can achieve multiple actions, such as lifting, pushing and pulling, and rotating.

Main Functions and Roles
Provide power: The main function of the hydraulic pump station is to provide the required power for the hydraulic system to ensure that the hydraulic equipment can work smoothly under various working conditions.
Pressure control: Through pressure control valves (such as overflow valves), hydraulic pump stations can maintain a constant working pressure in the hydraulic system to prevent system overpressure.
Flow control: The hydraulic pump station can adjust the flow of oil, thereby controlling the speed of hydraulic actuators and accurately adjusting the action of the hydraulic system.
Energy conversion: The hydraulic pump station converts the mechanical energy provided by the motor into hydraulic energy, and provides different oil flows and pressures according to the needs of the system to drive hydraulic mechanical equipment.
Safety protection: The hydraulic pump station is equipped with a variety of safety valves (such as overflow valves, safety valves), which can timely release excessive pressure in the system to prevent damage to hydraulic equipment.
Oil circulation and filtration: The hydraulic pump station circulates and cleans the oil through the oil tank and filter to maintain the normal operation of the system and extend the system life.

Application Areas

Metallurgical industry: Hydraulic pump stations are widely used in metallurgical equipment, responsible for providing high-pressure hydraulic oil to drive presses, shearing machines, die-casting machines and other equipment.
Mining machinery: The hydraulic system in mining equipment needs to provide hydraulic power through the pump station to drive mining, crushing, screening and other equipment.
Aerospace: Hydraulic pump stations are also important in the hydraulic systems of aircraft, satellites, and spacecraft, such as driving the landing gear, rudder, hatch and other operations of aircraft.
Hydraulic test bench: used to test and test hydraulic components to ensure the working performance and stability of hydraulic equipment.
Steel industry: Hydraulic pump stations provide power support for hydraulic equipment (such as hydraulic shears, hydraulic straighteners, etc.) in steel production lines.
Shipbuilding and marine engineering: In ship lifting, lifting platforms and other equipment, hydraulic pump stations provide hydraulic power to ensure the stable operation of ships and offshore platforms.
Automated production lines: In automated equipment and production lines, hydraulic pump stations provide power support to drive the movement of various automated machinery and equipment.

Maintenance and Maintenance
The normal operation of hydraulic pump stations is inseparable from regular maintenance and maintenance. Common maintenance measures include:
Regularly check the hydraulic oil: Check the quality and oil level of the hydraulic oil, replace the hydraulic oil regularly, and avoid oil contamination.
Clean the filter: Clean the hydraulic oil filter regularly to ensure the oil is clean and prevent system contamination.
Check the valve group and pump: Regularly check the working condition of the hydraulic valve and hydraulic pump to avoid leakage or abnormal pressure.
Check the cooling system: Ensure that the cooling system works normally to prevent overheating of the hydraulic oil.
Check the safety valve and overflow valve: Regularly check the working pressure of the safety valve and overflow valve to ensure its effectiveness.
Check the motor: Check the operating condition of the motor regularly to prevent overload or failure.
