FAQ;
What should be considered during commissioning and adjustment?
• Alignment: Ensure the coupling between the pump and motor has a gap of 3-5 mm to avoid thrust load on the pump's bearing, which could cause damage.
• Filling & Venting: Before starting, fill the pump casing with clean hydraulic fluid through the drain port to vent air. The drain line should be connected to the highest T port on the pump.
• Rotation Direction: Confirm the pump's specified rotation direction (viewed from the shaft end) and ensure the motor rotation matches. Incorrect rotation can damage the pump.
• Minimum Flow Setting: If the pump's minimum displacement is set too large, it may become impossible to lower the pressure setpoint by adjusting the control valve.
• DP Control Setup: For DP controls, the pressure differential across the pump's DP valve is the sum of the pre-set pressure differential on valve 2 and the differential set on valve 5 (at minimum pump displacement), typically set to a standard sum of 33 bar.
8. In which industries are A4VSO pumps commonly applied?
A4VSO pumps are widely used in high-pressure, heavy-duty industrial applications. Common industries include: ceramic presses, refractory material presses, steel and forging equipment, metallurgical machinery, mining machinery, marine machinery, petroleum equipment, engineering machinery, and machine tools.
Note: This FAQ is based on technical information from publicly available sources related to Bosch Rexroth's A4VSO series pumps. For precise commissioning, troubleshooting, and detailed specifications, always consult the official factory documentation and manuals specific to your pump model and control type.
