Description
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.
