(New Zealand swager cylinder,produced by Hengyu Group）

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

Introduction to swager cylinder:

The difference between the integral swager cylinder and the split swager cylinder: The integral swager cylinder and the split swager cylinder in the swager cylinder are two different swager cylinders, and they are very different. The whole swager cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split swager cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and swager cylinder damage. Therefore, it is obvious that the answer to this question is for difference.

The meaning of the swager cylinder model marked by the swager cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the swager cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the swager cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.

The piston rod and guide sleeve function of the swager cylinder is crucial: the relative motion pair between the piston rod and the guide sleeve is the main factor causing external leakage, if the chrome layer on the surface of the piston rod is spalling or producing longitudinal tensile marks due to wear, it will directly lead to the failure of the seal.

The internal leakage of the swager cylinder should be prevented when the swager cylinder is used. The internal leakage of swager cylinder includes the leakage caused by excessive wear of swager 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.

Answers to some questions about swager cylinder:

What is the cause of the sound of the excavator arm cylinder?
Hydraulic excavator cylinder includes boom cylinder, bucket rod cylinder and bucket cylinder, four cylinders. The sound of boom cylinder may be the wear of hydraulic cylinder block bushing, piston rod bushing and shaft pin. The main reason: poor lubrication, followed by improper clearance in the assembly process. Countermeasures: (1) Strictly lubricate each shaft pin at least once every 8 hours when the excavator is initially used for 100 hours and under harsh conditions; In other working conditions, lubricate each pin at least once every 50 hours. (2) If the lubricating oil passage is found to be blocked, it must be stopped for rectification. (3) Require assembly, replacement of all parts of the shaft pin, bushing strictly comply with the assembly testing standards and operating procedures.

Structural characteristics of the plunger cylinder? (1) The plunger hydraulic cylinder is a single-acting hydraulic cylinder, which can only move in one direction by hydraulic pressure, and the return trip of the plunger depends on other external forces or the weight of the plunger; (2) The plunger is only supported by the cylinder liner and is not in contact with the cylinder liner, so the cylinder liner is easy to process, so it is suitable for long stroke hydraulic cylinder; (3) the total pressure of the plunger during work, so it must have sufficient stiffness; (4) The weight of the plunger is often large, and it is easy to sag due to its own weight when placed horizontally, resulting in wear of the seals and guide side, so its vertical use is more favorable.
