(Britain trailer hydraulic cylinder,produced by Hengyu Group）

trailer hydraulic cylinder are widely used in Britain，because of no need for deceleration device，high work efficiency，excellent fatigue and impact resistance.So our company has designed trailer hydraulic cylinder for customers from Britain.

Introduction to trailer hydraulic cylinder:

There are some honeycomb holes in the inner wall of the trailer hydraulic cylinder, piston or piston rod surface. How is this formed? When we repair the trailer hydraulic cylinder, we can see that there are some honeycomb holes on the inner wall of the trailer hydraulic cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the trailer hydraulic cylinder is targeted to prevent. Is very necessary.

The trailer hydraulic cylinder should be vented: when the trailer hydraulic cylinder is installed or parked for a long time to work again, the air will penetrate into the trailer hydraulic cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the trailer hydraulic cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the trailer hydraulic cylinder, the oil is best entered and discharged from the highest point of the trailer hydraulic cylinder. trailer hydraulic cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

trailer 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 trailer 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.

In the process of using the trailer hydraulic cylinder, sometimes such a problem will occur, the trailer hydraulic cylinder can not act immediately after the instruction of the trailer hydraulic cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil trailer hydraulic cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

Answers to some questions about trailer hydraulic cylinder:

Why does the cylinder pop out of itself when it stops?
This situation has two possibilities, 1. There is more air in the system, so exhaust the gas. 2. The back pressure of the oil return is relatively large, check the oil return filter, check whether the cylinder has a rod cavity buffer is too tight, and choose a 3-position 4-way M-type valve for the reversing valve. In addition, after the shutdown, manually change the reversing valve back and forth several times, it should not rise out.

What is the meaning of cylinder ejection on the injection mold, and what is the difference between cylinder ejection and ordinary ejection?
Usually requires the front die ejection will use the cylinder to drive the thimble plate to achieve the ejection of the thimble. There is also a case that the mold is very large or long, and the balance of the ejector rod of the injection molding machine is not enough, and the cylinder ejector will also be used.
