Brazil hydraulic cylinder,steering cylinder manufacturer,steering cylinder

(Brazil steering cylinder,produced by Hebei Hengyu company）

steering cylinder are widely used in Brazil，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed steering cylinder for customers from Brazil.

Introduction to steering cylinder:

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.

When the hydraulic oil is not pumped into the steering cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the steering cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.

When the steering cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the steering cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.

If the seal of the steering cylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and steering cylinder, and the phenomenon of "pulling the steering cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operation and improvement should be done according to the installation instructions.

Answers to some questions about steering cylinder:

How to calculate cylinder speed?
If there is a throttle valve, the cylinder speed will be adjustable. When the throttle is fully opened, the speed of the cylinder reaches the maximum: maximum speed = oil pump displacement ÷ cylinder cavity cross-sectional area The displacement of the oil pump is a main indicator, which can be found on the nameplate, and some can also be known by the oil pump model; The cross-sectional area of the cylinder cavity can be easily calculated. Just make sure the units are the same. And because the cross-sectional area of the rod cavity and the rodless cavity of the cylinder is different, the speed of advance and retreat may also be different.

How to distinguish large cavity and small cavity of excavator rod cylinder ?
Single rod piston cylinder is a form of cylinder that is used relatively most, and the boom, bucket, dozer shovel cylinder are all in this form. Among them, the rodless cavity is also called the large cavity, and the rodless cavity is also called the small cavity. Therefore, the cylinder cavity on the side with the exposed piston rod is the small cavity, and the cylinder cavity on the side without the exposed rod is the large cavity.
