Vickers PVM18/45/57/74/98/131/141 Hydraulic Piston Pump Detailed Information
Overview
The Vickers PVM series hydraulic piston pumps are a significant product under the Vickers brand, featuring various models including PVM18, PVM45, PVM57, PVM74, PVM98, PVM131, and PVM141 to meet the needs of different application scenarios. These pumps serve as vital hydraulic components for transmitting pressurized liquid in hydraulic systems, converting the mechanical energy of power machines (such as electric motors and internal combustion engines) into the pressure energy of liquid.
Working Principle
The working principle of the Vickers PVM series hydraulic piston pumps is primarily based on the reciprocating motion of the plunger within the cylinder block. When the plunger moves backward, a certain degree of vacuum is formed, allowing oil from the reservoir to enter the pump through the suction pipe under the action of atmospheric pressure. When the plunger moves forward, the volume of the sealed working chamber decreases, causing the oil to be compressed and pressurized, which is then pumped into the system through the oil pipe. This reciprocating motion allows the pump to continuously provide pressurized oil for the hydraulic system.
Performance Parameters
The performance parameters of the Vickers PVM series hydraulic piston pumps vary by model but typically include the following aspects:
1. Displacement: Refers to the volume of liquid discharged per revolution of the pump due to changes in the geometric dimensions of the sealed chamber. Different PVM series pumps have varying displacement ranges to meet different flow rate requirements.
2. Pressure: Includes working pressure and rated pressure. Working pressure refers to the pressure of the oil output by the pump during actual operation, determined by the external load; rated pressure refers to the highest pressure under normal operating conditions that the pump can continuously operate according to test standards.
3. Speed: Refers to the actual rotational speed of the pump during operation. The rated speed refers to the highest speed at which the pump can continuously operate normally under rated pressure.
4. Efficiency: Includes volumetric efficiency and mechanical efficiency. Volumetric efficiency refers to the ratio of the actual output flow rate of the pump to the theoretical flow rate; mechanical efficiency refers to the ratio of the theoretical torque to the actual input torque of the pump.
Application Fields
Due to their high efficiency, reliability, and durability, the Vickers PVM series hydraulic piston pumps are widely used in various engineering machinery, metallurgical equipment, mining machinery, shipbuilding, and other fields. These pumps provide a stable and reliable source of pressurized oil for various hydraulic systems, ensuring the normal operation of equipment.
Maintenance and Servicing
To ensure the long-term stable operation of the Vickers PVM series hydraulic piston pumps, regular maintenance and servicing are required. This includes checking the sealing performance of the pump, cleaning the reservoir and filters, replacing worn parts, etc. Additionally, it is important to maintain the cleanliness of the oil and appropriate oil temperature to extend the lifespan of the pump.
In summary, the Vickers PVM18/45/57/74/98/131/141 hydraulic piston pumps are high-performance, widely used hydraulic piston pump products.
