Hydraulic support Jack - single telescopic column working principle

When a single telescopic column rises, the pressure fluid brought by the control valve enters the piston chamber of the column from the lower cavity joint, so that the live column rises to stop when the top beam and the roof contact.

When the single telescopic column is loaded, the roof pressure is transferred to the live column through the roof beam, and the hydraulic check valve and safety valve are the pressure liquid and unloading pressure of the closed piston chamber respectively.

When the single telescopic column falls, the pressure fluid enters the piston rod cavity through the upper cavity joint, and opens the one-way valve to clear the control valve and the return fluid pipeline, and the function of the live column in hydraulic and dead weight decreases.

Hydraulic support jacks - single telescopic column is mainly composed of cylinder block, movable column, guide sleeve, seals.

The cylinder block is the main body of the column in the outer layer, the cylinder block has the upper cavity joint and the lower cavity joint which can be connected with the control valve, in the hydraulic support assembly, the cylinder bottom should be connected with the base of the support.

Live column can work in the cylinder, is an important component in the hydraulic cylinder transmission.

The guide sleeve is the guide part of the movable column in the reciprocating movement. The guide sleeve has the guide ring and polyurethane rod seal, which constitute the guide and seal of the movable column in the movement. The outer surface of polyurethane is sealed to form a cylinder body.
