(Costa Rica supporting cylinder,produced by Hengyu Hydraulic Co., Ltd）

supporting cylinder are widely used in Costa Rica，because of long service life，smooth movement，high work efficiency.So our company has designed supporting cylinder for customers from Costa Rica.

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.

If air enters the hydraulic system, the supporting cylinder will not operate normally, mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced.

If it is found that the supporting cylinder lubrication is poor or the supporting cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the supporting cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the supporting cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the supporting cylinder center line. In this way, when the piston works in the supporting cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the supporting cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

supporting cylinder piston rod material selection and requirements: ① piston rod is usually made of 45 steel. When there is a large impact force and heavy load transmission, it is made of 40Cr steel. This is to ensure that the piston rod has sufficient working strength. The piston rod is generally designed as a supporting cylinder, if the diameter is larger, the hollow piston rod can be used. Made of No. 45 seamless steel pipe. ③ When the piston rod is manufactured, the blank should be first forged and conditioned after mechanical rough processing, and the hardness of HB=230 ~ 250. The purpose of conditioning is to improve the machining performance and increase the working strength of the material. ④ The surface roughness Ra of the piston rod after finishing should not be greater than 0.65μm. ⑤ In order to improve the corrosion resistance of the piston rod, the working surface of the rod can be plated with hard chromium. ⑥ The piston rod and the end cap are guided by H8 ' supporting cylinder piston rod industry standard: piston rod diameter series of national recommended standard GB/T2348-1993. Piston rod thread size series standard GB/T2350-1980. Please refer to execute. There is no industry standard for piston rods Both the supporting cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The supporting cylinder mainly outputs linear motion and force. The supporting cylinder has a variety of forms, according to the different characteristics of its mechanism it can be divided into piston type, plunger type and swing type three categories, according to the mode of action he can be divided into single action and double action. Piston supporting cylinder, plunger supporting cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger supporting cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.

Answers to some questions about supporting cylinder:

Does the sealing string of the upper and lower chamber of the hydraulic cylinder fall by itself?
It is possible, the probability accounts for 85% (depending on the weight), the weight is less than the system resistance, may not fall, the weight is greater than the system resistance, will not necessarily fall, so often check the equipment, safety first, find the problem in time to solve, the cylinder is not very expensive parts, maintenance does not cost much money, However, accidents caused by cylinder failure will lose several times the cost.

The difference between the overall cylinder and the separate cylinder of the truck?
The whole cylinder is cast in one piece, and such a cylinder generally does not leak oil. Split cylinder refers to two welded, easy to leak oil in the welding place, resulting in damage to the cylinder, or its body can not get up, many people do not use this kind of cylinder now.
