Variable Axial Piston Pumps for Open Circuit C1 series
Variable Axial Piston Pumps for Open Circuit C1 series
Variable axial piston pumps (PVC1 series) are designed for open-type hydraulic systems in both mobile and stationary machines. They convert mechanical energy into hydraulic energy, with a displacement range of 28 to 85 cm3, a rated pressure of 210 bar, and a maximum pressure of 250 bar. These pumps operate at speeds up to 3200 min-1, offering high energy efficiency and reduced heat dissipation.
The PVC1 series features an adjustable swash plate design, suitable for agricultural machinery like tractors and combines. An LS control system adjusts the swash plate angle based on system pressure, optimizing flow according to load requirements.
A detailed schematic of the PVC1 pump components is provided, including the shaft, plunger, control system, body, cylinder block, and various seals and bearings.
Ordering codes are available for different configurations of the PVC1 pumps, covering displacement, control options, rotation direction, drive shaft specifications, and climatic versions.
The pumps come in sizes with displacements of 28, 45, 63, and 85 cm3, with a rated flow ranging from 58 to 159.8 l/min and requiring input power between 25.35 and 70.94 kW. Formulas for calculating torque, flow, and power are included.
Detailed dimensions for various models of the PVC1 pumps are provided, including mounting flange specifications and port options for suction, pressure, and control lines.
Different control systems are outlined, including pressure control (RP), pressure and flow control (RPF, RPF1), and remote pressure control (RPR).
Guidelines for selecting hydraulic fluids, permissible viscosity parameters, and installation instructions are included. The document also covers filtration, shaft sealing, and hydraulic system requirements.
Short-term minimum (cold start): -40ºC; Long-term: +75ºC; Maximum peak (at the outlet of the drain port): +100ºC.
Select hydraulic fluid based on operating temperature and viscosity. The fluid should maintain viscosity within the allowable range across all temperatures. VG 68 is recommended for higher temperature classes.
High-quality hydraulic fluids with additives are required, with properties like anti-corrosion, anti-oxidation, and anti-foaming. Mineral oil group HLP according to DIN51524 is recommended.
Optimal (constant): 20-30 mm²/s; Maximum start-up: 1500 mm²/s; Minimum short-term: 10 mm²/s.
Higher filtration fineness improves fluid purity and extends the life of axial piston units. Fluid purity should meet ISO 4406 standards, requiring a purity grade of at least 19/17/14.
The life of the shaft seal depends on alignment, rotation speed, and drainage pressure. High drainage pressure reduces seal life.
Use "clean" oil to prevent damage. Install a mesh filter with a 25 μm cell size at the reservoir inlet or pump.
Fill the axial piston unit with hydraulic fluid and bleed air during commissioning. Ensure suction and drain lines flow below the minimum fluid level, with a maximum suction height of 800 mm.
Below-reservoir installation: The unit is installed outside the reservoir below the minimum fluid level. Above-reservoir installation: The unit is installed above the minimum fluid level. In-tank installation: The unit is installed below the minimum fluid level.
Outlines installation procedures for components within a tank, focusing on the suction line, filling and air removal, and connecting the drain line.
- Minimum Required Loading Depth: 200 mm
- Minimum Required Distance to Tank Bottom: 100 mm
- Minimum Required Height to Prevent Fluid Draining: 25 mm
- Maximum Permissible Suction Height: 800 mm
Ensure adequate spacing between the suction and drain lines to prevent operational inefficiencies and potential damage.
- Suction Line (S): Critical for fluid intake.
- Filling/Air Removal (F): Necessary for maintaining system efficiency.
- Drain Line Connection (L, L1): Important for fluid management.
- Damping Wall (SB): Used to reduce vibrations and noise.
