(Sudan hoister hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

hoister hydraulic cylinder are widely used in Sudan，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed hoister hydraulic cylinder for customers from Sudan.

Introduction to hoister hydraulic cylinder:

How the cavitation of the hoister hydraulic cylinder is formed: With the gradual rise of pressure, the gas in the oil will become bubbles, when the pressure rises to a certain limit value, these bubbles will break under the action of high pressure, so that the high temperature and high pressure gas will quickly act on the surface of the parts, resulting in cavitation of the hoister hydraulic cylinder, resulting in corrosive damage to the parts.

The hoister hydraulic cylinder pipe should not be left behind when deburring at both ends after the fixed length processing. In addition, the placement of steel pipes near the site of welding pipeline operations is the cause of welding foreign objects. The pipes placed near the welding operation site should be sealed. It must also be noted that pipe fitting materials should be fully prepared on a dust-free workbench.

hoister hydraulic cylinder piston rod material selection and technical requirements: (I), because there is no special requirements, so use 45 steel as the piston rod material, the design of the piston rod only withstand pressure stress, so no modulation processing; (ii) The coaxial tolerance of the shaft journal and the outer circle of the mounting piston is not greater than 0.01mm, so as to ensure the coaxial degree of the outer circle of the piston rod and the outer circle of the piston, and avoid the stuck phenomenon of the piston and the hoister hydraulic cylinder, the piston rod and the guide. The vertical tolerance between the end face of the mounting piston and the axis of the piston rod is not more than 0.04mm/100mm to ensure that the piston installation does not produce skew; (iii) The outer circle of the piston rod should pay attention to the roughness; (iv) Because it is operated under low load conditions, surface treatment is omitted.

The hoister hydraulic cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure hoister hydraulic cylinder can use 20 steel pipe, and the high pressure hoister hydraulic cylinder can use 45 steel pipe.

Answers to some questions about hoister hydraulic 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.

Is a hydraulic cylinder and a jack the same thing?
Strictly speaking, no. Although the hydraulic principle is used, and even some of the longer jacks are similar to the cylinder, the internal structure of the two is different. There is a check valve inside the jack. After the top lift, the check valve locks the hydraulic oil circuit, and the hydraulic oil only enters and does not exit after the check valve locks, and can be lowered to complete a reciprocating movement. The cylinder is usually connected to the distribution tube to control the movement, and works with a wide variety of distribution valves and distribution systems according to different needs. The jack only needs a simple check valve.
