PVXS Series Hydraulic Plunger Pump
Product Overview
The PVXS series hydraulic plunger pump is a high-performance, high-reliability hydraulic pump widely used in various hydraulic systems. This series of pumps adopts an axial plunger structure with a swashplate design, featuring high pressure, large flow rate, and long service life.
Product Models and Specifications
The PVXS series hydraulic plunger pump includes multiple models, such as PVXS-066, PVXS-090, PVXS-130, PVXS-180, PVXS-250, etc., to meet the needs of different customers. Each pump model can operate at a working pressure of up to 420 bar and has a rated speed of up to 1800 min^-1 or higher.
Product Features
1. High Reliability: The axial plunger pump structure with a swashplate design makes the pump body more compact and stable, improving its reliability and service life.
2. High Pressure: The pump's working pressure can reach 420 bar, meeting the demands of high-pressure hydraulic systems.
3. Large Flow Rate: Optimized plunger design increases the pump's flow rate output, making the hydraulic system more efficient.
4. Integrated Design: The integrated design of the control pump, filter, and relief valve makes the pump body more compact, easy to install and maintain.
5. Flexible Control Methods: Multiple control methods such as DF control, DQ control, and LR control are provided to meet the needs of different control systems.
6. Wide Application Areas: The "modular block" design allows these pumps to be widely used in various fields, such as engineering machinery, metallurgical equipment, shipbuilding, etc.
Working Principle
The working principle of the PVXS series hydraulic plunger pump relies on the reciprocal motion of the plungers in the cylinder block to achieve the suction and discharge of liquid. When the plunger moves backward, the volume in the cylinder block increases, forming a negative pressure and thus sucking in liquid; when the plunger moves forward, the volume in the cylinder block decreases, increasing the pressure and thus discharging the liquid. Through continuous reciprocal motion, the pump can continuously output high-pressure liquid.
Maintenance and Servicing
To ensure the normal operation and extend the service life of the PVXS series hydraulic plunger pump, regular maintenance and servicing are required. Specific tasks include:
1. Checking whether the fasteners of the pump are loose or damaged and replacing or tightening them as needed.
2. Inspecting the integrity of the pump's seals and replacing them if worn or damaged.
3. Regularly cleaning the pump body and filter to remove impurities and dirt.
4. Checking the wear condition of the pump's bearings, gears, and other moving parts and replacing them as needed.
5. Regularly checking the pump's working pressure and flow rate to ensure its normal operation.
In summary, the PVXS series hydraulic plunger pump is a high-performance, high-reliability hydraulic pump product with a wide range of applications and superior performance characteristics. Through reasonable maintenance and servicing, the normal operation of the pump can be ensured and its service life extended.
