(Costa Rica yg series hydraulic cylinder,produced by Hengyu Group）

yg series hydraulic cylinder are widely used in Costa Rica，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed yg series hydraulic cylinder for customers from Costa Rica.

Introduction to yg series hydraulic cylinder:

When the piston speed of the yg series hydraulic cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the yg series hydraulic cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.

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

When the yg series hydraulic cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the yg series hydraulic cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil yg series hydraulic cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical yg series hydraulic cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the yg series hydraulic cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.

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

Answers to some questions about yg series hydraulic cylinder:

Classification and application of cylinders.
Hydraulic cylinder is divided into single acting hydraulic cylinder, double acting cylinder, combined hydraulic cylinder, swing hydraulic cylinder. Single acting cylinder is divided into plunger type hydraulic cylinder, single piston rod hydraulic cylinder, double piston rod hydraulic cylinder, telescopic hydraulic cylinder. Plunger type hydraulic cylinder: the plunger moves only in one direction, and the return stroke is to push the plunger back using its own weight or load. Single piston rod hydraulic cylinder: The piston moves only in one direction, and the return stroke is to push the plunger back using dead weight or load. Double piston rod hydraulic cylinder: both sides of the piston are equipped with piston rods, and pressure oil can only be supplied to one side of the piston. The return stroke usually uses spring force, gravity or external force. Telescopic hydraulic cylinder: It obtains long stroke with short cylinder. The hydraulic oil is pushed out from large to small section by section, and the external force is reduced from small to large.

What are the reasons why the hydraulic cylinder action is slower than normal?
There are many factors that cause this problem. First, measure the pressure of the main system to see whether the pressure of the main system under the pressure state is consistent with the initial setting. Before measuring the pressure, it is best to check the hydraulic oil and suction oil filter and replace or clean it. Second, check the main relief valve of the reversing control multiway valve to see if there is damage or foreign matter blocking, and clean it. If your pump is a gear pump, the problem should generally be small. Second, look at traffic. There is no leakage in the cylinder, leakage in the reversing valve spool and so on.
