Causes and Solutions of Slow Speed of Four-Column Hydraulic Press

Hydraulic Press Reasons for Slow Return:

The Oil Viscosity in the Hydraulic System Is Too High and the Resistance Increases, Resulting in Slow Return.

The Oil Temperature in the Hydraulic System Is Too Low, Resulting in Increased Oil Viscosity, Increased Resistance and Slow Return.

There Are Gases Or Impurities in the Oil in the Hydraulic System, Resulting in Poor Oil Flow and Slow Return.

Hydraulic Cylinder Seals in the Hydraulic System Are Worn Or Aged, Resulting in Leakage and Reducing Return Speed.

Solution:

Replace the Low Viscosity Hydraulic Oil Or Add Antiwear Agent to the Hydraulic System to Reduce the Viscosity of the Oil.

In the Hydraulic System, the Heater Or Heat Exchanger Increases the Oil Temperature and Reduces the Oil Viscosity.

Clean the Oil in the Hydraulic System and Replace It with a New Hydraulic Oil to Keep the Content of Gas and Impurities in the Oil Low.

Replace the Hydraulic Cylinder Seal. Regularly Check and Replace the Seals to Ensure the Normal Operation of the Hydraulic Cylinder.
