1 endoleaks:
Endoleaks is common forklift hydraulic cylinder lifting unable or can not be lifting fork its own decline and

its own forward door frame failure.
Analysis and elimination of the internal leakage:
(1) between the stem and valve wear gap is too large
 &nb sp;  Accelerate the wear of the stem and the body due to the distribution valves for long-term use or fluid

dirty,forklift rotator attachment
destroyed with the sealing surface, resulting in oil spills. Repair the valve stem wear lighter stem

chrome-plated polished; if the stem is badly worn, you will need to be replaced
(2) Valve between the oil spill
   Seal failure, the inner leakage; installation body the performance of injury or O-ring worn or damaged

valve between the hydraulic effect,skid steers attachments
is also prone to leakage.
  Body damage is required for grinding, replacement O-ring, according to the order and torque tighten the

bolts.
(3) safety valve spring failure
 If the safety valve spring failure, hydraulic oil under pressure below the system requirements can force the

ball to leave the valve position into the oil spill Road, resulting in leakage, the system failure.
Management must replace the spring, and then use the adjustment screw to adjust the spring pressure to the

provisions of 14 Mpa. Adjust the load when the demand from the load center of 600mm at 7.5t cargo, goods like

from the non-starting with locking nut, this time the pressure is the need to adjust the pressure.
(4) multi-valve rod can not be reset
If the stem can not be reset, the trench connected with the oil passages, will produce leakage.
First, stem return spring deformed or damaged, the lower spring force and not make the stem back in place,

repairs are required to replace the spring;
Between body and stem are dirty, have a greater resistance to stem the reset difficulties, internal multi-

channel valve repair should be washed to eliminate the resistance.
(5) poppet valve wear
   The poppet valve is used to prevent fluid backflow. If the cone valve wear, oil Road off Mission lax, the

hydraulic oil will return, so that the system failure. Repair, response into the grinding or replacement.

Elimination of reflux
2, valve oil leakage
The sealing of the stem and the body rely on the O-ring seals aging or damaged in the system under pressure

hydraulic oil will flow along the stem, lea ding to body oil leakage. Troubleshoot this, simply replace the O-

ring can.
