Introduction to Parker Hannifin
Parker-Hannifin Corp. is a diversified motion and control technology and systems producer that offers precision-engineered solutions for a range of mobile, industrial, and aerospace sectors. One of the most prominent goods from this company is hydraulic equipment.
On the other side, Zuosen Hydraulic is the original producer of the Parker hydraulic pump. As a result, you can get replacement components compatible with authentic parker products. The theme discussed next is the parker hydraulic pump – PV series built from the Zuosen factory.
Parker Hydraulic Pump – PV Series
Zuosen Hydraulic Manufactures Parker piston pumps – PV series to withstand the rigors of heavy-duty industrial and marine applications. This open circuit, swashplate-type axial piston pump delivers excellent productivity and power density to its customers, with pressure ratings of up to 420 bar and high-speed ratings.
Parker hydraulic pumps - PV series pumps are distinguished by their excellent conversion flexibility, in addition to their ruggedness and extraordinarily long service life. Every parker hydraulic pump - PV series pump comes standard with an inbuilt pre-compression volume, ensuring low ripple operation and noise emissions.
A wide variety of displacements and control choices also enables diverse applications.
Low noise, quick response, service-friendly, high self-priming speed, compact design, and through drive for 100 percent nominal torque are all features of the Parker hydraulic pump - PV series pumps.
We indicate HLP oils to DIN 51524 or ISO6743/4 as high-quality hydraulic mineral fluids (HM & HV). For typical applications, we suggest Brugger-values of 30 N/mm2, with 50 N/mm2 for severely loaded hydraulic equipment, quick cycling machines, and high dynamic loads, as measured according to DIN 51 347-2. Document MSG30-3248/UK Parker Hydraulic Fluids is also available.
Installation and Start-up
According to the manufacturer's instructions, you must carefully install any equipment or system to operate safely and without disturbance. The different industries may use hydraulic designs for various purposes and need varied start-up processes.
In this regard, the parker hydraulic pump is only a necessary part of the overall system. As a result, a generic start-up guide may provide a wealth of helpful information. Nonetheless, depending on the nature of the system or power unit, supplement it with appropriate modifications.
You must follow the following procedures appropriately during installation and start-up:
Ascertain that all shipping components are entire, free of damage, contamination from the outside, and sufficiently covered against contamination intrusion.
Contamination of any type is a hydraulic component's worst enemy. Unfortunately, however, it remains the most common cause of component failure. As a result, you must ensure extreme caution and cleanliness while handling and controlling items that come into touch with hydraulic fluid.
Cover all ports until installing the pipes or hoses to the pumps and other components. Assemble in a dry, dust-free environment whenever possible. Only use appropriate tools.
To minimize excitation of the whole system owing to pump vibrations, avoid complex connections from the pump to the reservoir lid or frame and intake and exit pipes.
Cut suction pipe entrance under 45°, position to the side or bottom, max fluid velocity approx. v = 0.5 m/sec. Minimum distance from bottom 2 - 3 times diameter and approx. 200 mm below fluid level, even at the lowest fluid level. Even during compensating, the inlet pressure should never go below 0.8 bar.
For pipe, hose, and connections, choose the appropriate pressure rating. In this case, consider the pressure peaks in this example.
Dimension the pipe according to the port size. Use flexible port connections to prevent system excitation.
Use the pump's highest drain port at all times. The drain port must be higher than the pump centerline, or you must install an extra air bleed line. You should not combine the pump drain line with other return and drain lines. The pump must not be capable of running dry. During compensation, the maximum case pressure allowed is 0.5 bar (2 bar peak).
Use elastic coupling with no axial or radial reaction forces for direct driving. Please rigorously observe the coupling supplier's recommendations regarding axial clearance, axial displacement, and angular tolerances.
You must not install couplings using a hammer. In this case, you can mount the connection smoothly thanks to threads on the shaft end.
Check the qualities of the voltage, current, phase, and connection. Check the direction of the motor's rotation as well.
The reservoir must meet all system criteria for design, size, position, and ports. In this case, the system uses the tank for heat dissipation, air removal, water removal, and contaminant sedimentation and is a reservoir for hydraulic fluid.
Filling of the system
Follow DIN 51524 part 2 and use only high-quality mineral oil-based fluids, such as HLP oils. Don't hesitate to contact the Zuosen service station for additional fluids (HFC, HFD, biodegradable, or synthetic fluids) and check the Hydraulic Fluids Information in the Catalogue.
Pay the closest attention to cleanliness!
Only use filtering equipment to fill the system. When the elements contamination of the refill fluid reaches class 10 (contamination level 19/16 according to ISO 4406), use filter equipment. The contamination levels in hydraulic fluid provided in barrels are usually higher.
Filtration is critical to the hydraulic system's long-term performance. According to statistical analysis, the system or component failure requires contamination. Therefore, filter the return line, pressure, and bypass lines.
Filling of the pump case
The pump casing must be filled through the drain port to guarantee lubrication, sealing, and a smooth start-up.
Check to see whether all ports are connected appropriately and following the specifications. As a result, all connections have been tightened, and you have done all modifications.
Troubleshooting and Maintenance
Generally, all hydraulic piston pumps encounter similar issues. In this scenario, we must thoroughly understand each problem to troubleshoot them. In the article Rexroth Hydraulic Piston Pump, a section on troubleshooting and maintenance will guide you to solve the issues.
