(Costa Rica stern plate hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

stern plate hydraulic cylinder are widely used in Costa Rica，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed stern plate hydraulic cylinder for customers from Costa Rica.

Introduction to stern plate hydraulic cylinder:

When the control pressure of the hydraulic system is too low, the stern plate hydraulic cylinder will appear wrong or no action, because the throttle resistance in the control pipeline may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is interfered with. At this time, check the control pressure source to ensure that the pressure is adjusted to the specified value of the system.

stern plate hydraulic cylinder piston rod material selection and technical requirements: (I), because there is no special requirements, so use 45 steel as the piston rod material, the design of the piston rod only withstand pressure stress, so no modulation processing; (ii) The coaxial tolerance of the shaft journal and the outer circle of the mounting piston is not greater than 0.01mm, so as to ensure the coaxial degree of the outer circle of the piston rod and the outer circle of the piston, and avoid the stuck phenomenon of the piston and the stern plate hydraulic cylinder, the piston rod and the guide. The vertical tolerance between the end face of the mounting piston and the axis of the piston rod is not more than 0.04mm/100mm to ensure that the piston installation does not produce skew; (iii) The outer circle of the piston rod should pay attention to the roughness; (iv) Because it is operated under low load conditions, surface treatment is omitted.

The piston seal of the stern plate hydraulic cylinder is the main element to prevent leakage in the stern plate hydraulic cylinder. For the lip seal, it should focus on checking whether the lip edge is bruised and worn, and for the combination seal, it should focus on checking the wear of the sealing surface, and then determine whether the seal can be used. In addition, it is necessary to check whether the static seal between the piston and the piston rod is crushed. The piston rod seal should focus on checking the wear of the seals and supporting rings.

Piston stern plate hydraulic cylinder is widely used in hydraulic transmission. When the stern plate hydraulic cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the stern plate hydraulic cylinder, and uses the pressure difference of hydraulic oil on both sides of the piston to realize the reciprocating movement of the piston. If you want to speed up the forward speed of the piston, the return oil in the stern plate hydraulic cylinder can be controlled by the valve and directly input into the inlet pipe to participate in the work of the piston to achieve rapid movement of the piston, but the thrust of the piston is reduced much.

Answers to some questions about stern plate hydraulic cylinder:

How to distinguish loader boom and forearm hydraulic cylinder? Is it the upper arm or the lower arm?
The one in the middle that can flip the bucket is the small arm cylinder you say, and the one that lifts the brackets (big arms) on both sides is the big arm cylinder.

How to remove the air in hydraulic cylinder?
Connected the cylinder to the system, and reciprocating move with full stroke several times, then the air can be eliminated . There is also a clunky method as follows: first remove the rod cavity oil pipe, connect the rodless cavity oil circuit to extend all the cylinders, and then remove the rodless cavity oil pipe, connect the rod cavity oil pipe and withdraw all the cylinders, and then connect the rodless cavity oil pipe, so that there is no air in the cylinder.
