Dominica hydraulic cylinder,reset cylinder manufacturer,reset cylinder

(Dominica reset cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to reset cylinder:

reset 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 reset 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 ' reset 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 reset cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The reset cylinder mainly outputs linear motion and force. The reset 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 reset cylinder, plunger reset cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger reset cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.

reset cylinder to reasonable use of hydraulic oil: strict hydraulic oil selection off. Hydraulic oil is selected in strict accordance with oil standards. The selection of good quality hydraulic oil can effectively prevent bubbles in the working process of the hydraulic system. When choosing the oil, it should be selected according to the lowest temperature in different regions, and fill the hydraulic oil according to the dipstick standard, and at the same time, it should also keep the hydraulic system clean (when filling the hydraulic oil, it should prevent the water and other impurities into it), and often check the oil quality, oil level and oil color of the hydraulic oil. If blisters and bubbles are found in the hydraulic oil. When the oil becomes milky white, the source of the air in the oil should be carefully found and eliminated in time.

In use, the reset cylinder should try to avoid the friction iron powder or iron filings formed by buffering the plunger. When the matching gap of the buffer device is small and the transverse load on the piston rod is large, the sintering phenomenon may be caused. These friction iron powder or the metal fragments that have fallen off as a result of sintering will remain in the reset cylinder.

When the piston speed of the reset cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the reset cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.

Answers to some questions about reset cylinder:

What's a minus 40 cylinder made of?
Construction with 1Cr18Ni9Ti, in low temperature conditions impact and tensile strength are very good, can withstand -100 degrees of low temperature, corrosion resistance, material price is not very high, more economic.

What is the main maintenance of the cylinder?
After disassembling the cylinder: 1, clean the cylinder and piston; 2, replace all seals; 3, if there is a valve to repair, to ensure sealing and flexible; 4, deal with all deformation parts; 5. Installation experiment.
