Oman hydraulic cylinder,large cylinder manufacturer,large cylinder
(Oman large cylinder,produced by Hengyu Group）
large cylinder are widely used in Oman，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed large cylinder for customers from Oman.
When the piston speed of the large cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the large cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.
When the large cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the large cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.
We can not just consider the price and ignore the quality when we purchase the large 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 large 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 large cylinder is not required.
The internal leakage of the large cylinder should be prevented when the large cylinder is used. The internal leakage of large cylinder includes the leakage caused by excessive wear of large cylinder block seal, piston rod and seal cover seal and piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time.
Are hydraulic cylinders divided into oil cylinders and water cylinders? What's the difference between the two types?
There are oil cylinders and water cylinders. The two cylinders are used in different environments. Oil cylinders are generally used in places where there is less demand for media, which is our most common hydraulic cylinders. Water cylinders are mainly used for large tonnage presses. Because the equipment is too large, the use of hydraulic oil will cause a relatively large waste. However, water is not pure water, there are oil-in-water emulsion and water-in-oil emulsion. Water has another benefit: it's flame retardant. It is especially suitable for some flammable and explosive occasions. Or with water glycol. The use of pure water is very little, mainly because the seal is not good and easy to rust.
How big gear pump need to use for 60*100 cylinder?
One cylinder size alone does not determine the size of the pump used. Choose the size of the pump, at least to know 1, the size of the load is how much, by the size of the load and the size of the cylinder and other conditions can be calculated the pressure required by the hydraulic system. 2. Speed of operation. From this speed and cylinder size, the required flow rate of the system is calculated. The relevant parameters of the pump can be selected by the pressure and flow rate to determine what kind of pump is required.
