Ghana pusher hydraulic cylinder

(Ghana pusher hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)

pusher hydraulic cylinder are widely used in Ghana,because of no need for deceleration device,long service life,smooth movement.So our company has designed pusher hydraulic cylinder for customers from Ghana.

Introduction to pusher hydraulic cylinder:

We can not just consider the price and ignore the quality when we purchase the pusher hydraulic cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the pusher hydraulic cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the pusher hydraulic cylinder is not required.

The pusher hydraulic cylinder should be used correctly and maintained regularly. The pusher hydraulic cylinder should be deflated before use, the buffer regulating valve should be adjusted to a reasonable position, the cleanliness of the oil should be checked regularly, the dust on the pusher hydraulic cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.

pusher hydraulic cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the pusher hydraulic cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the pusher hydraulic cylinder. c. The pusher hydraulic cylinder seal is extruded, if the O-ring is obviously extruded at the pusher hydraulic cylinder seal, replace the pusher hydraulic cylinder seal.

pusher 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 pusher 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.

Answers to some questions about pusher hydraulic cylinder:

What diameter cylinder is needed for a force of 5 tons?
It depends on the pressure of your system pump. If the normal working pressure of the system is about 8MPa, then the diameter of the cylinder should be 100 mm.

What is the reason for the hydraulic cylinder sticking out and not retracting?
There are two reasons: First, the problem with the seal, if there are two seals on the piston, the top seal is broken. Second, when the hydraulic pressure itself is designed, the rod cavity area is too small, so that the desired return force can not be achieved during the return trip. You can first check whether the coupling is damaged; Then see if the relief valve in the oil line block is blocked. If the use time is too long, it needs to be cleaned, the hydraulic oil is very dirty and can block oil block. Electromagnetic directional valves can also be checked, but the chance of problems is relatively small, unless there is a product problem.
