Kazakhstan hydraulic cylinder,supporting cylinder manufacturer,supporting cylinder

(Kazakhstan supporting cylinder,produced by Hengyu Group）

supporting cylinder are widely used in Kazakhstan，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed supporting cylinder for customers from Kazakhstan.

Introduction to supporting cylinder:

The coordination of the sliding parts of the supporting cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.

When the supporting cylinder is installed, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the supporting cylinder head, earring (or middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent rigid interference and cause unnecessary damage.

supporting cylinder spool stuck or valve hole blocked How to solve: When the flow valve or direction valve spool stuck or valve hole blocked, the supporting cylinder prone to misoperation or action failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium.

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

How many boom cylinders, bucket rod cylinders and bucket cylinders are there in a small single-bucket excavator?
one for bucket, one for forearm, only one piece for a small excavator under the big arm, two pieces for medium and large excavator.

Hydraulic cylinder application areas?
1, in the machine tool industry, 85% of the machine tool transmission system adopts hydraulic transmission and control. Such as grinding machine, milling machine, planer, broaching machine, press, shearing machine, and combined machine tools. 2, in the metallurgical industry, electric furnace control system, rolling mill control system, open furnace charging, converter control, blast furnace control, strip deviation and constant tension device are all using hydraulic cylinders. 3, in the construction machinery, the general use of hydraulic transmission, such as excavators, tire loaders, truck cranes, crawler bulldozers, tire cranes, self-propelled scrapers, graders and vibration rollers. 4, in agricultural machinery, the use of hydraulic cylinders is also widely used, such as combine harvesters, tractors and so on.
