Estonia hydraulic cylinder,steering cylinder manufacturer,steering cylinder

(Estonia steering cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to steering cylinder:

Causes and countermeasures of oil steering cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the steering cylinder will lead to premature wear of the piston seal, replace the piston seal; If the steering cylinder is visibly scarred, the steering cylinder must be replaced. It can be pressurized at one end of the steering cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most steering cylinder piston drift may not come from the steering cylinder, the above method to determine the steering cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.

steering 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 steering cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the steering cylinder. c. The steering cylinder seal is extruded, if the O-ring is obviously extruded at the steering cylinder seal, replace the steering cylinder seal.

The steering cylinder should be vented: when the steering cylinder is installed or parked for a long time to work again, the air will penetrate into the steering cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the steering cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the steering cylinder, the oil is best entered and discharged from the highest point of the steering cylinder. steering 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.

The steering cylinder can not be used as grounding electrode to avoid electric damage to the piston rod.

Answers to some questions about steering cylinder:

How to calculate the inner diameter of the hydraulic cylinder?
These two parameters need the following information to decide: 1, pump displacement, speed (to get the actual output flow of the pump) 2, three and time requirements (lift time, drop time takes a few seconds) and then view the close cylinder series according to the results. Select the right cylinder.

What is the relationship between medium cylinder and side cylinder ratio of forklift truck?
The middle cylinder and the side cylinder seem to have no relationship, as long as the lifting speed required by the design can be ensured, but the diameter of the cylinder can not be too thin, so as to avoid the middle cylinder acting first when the high gantry vibration lifting, and then the two cylinders acting again.
