Libya hydraulic cylinder,roller press hydraulic cylinder manufacturer,roller press hydraulic cylinder(Libya roller press hydraulic cylinder,produced by Hengyu Group)
roller press hydraulic cylinder are widely used in Libya,because of no transmission clearance,powerful torque,clever hydraulic energy conversion.So our company has designed roller press hydraulic cylinder for customers from Libya.
roller press hydraulic 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.
roller press hydraulic 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 roller press hydraulic 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 ' roller press hydraulic 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 roller press hydraulic cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The roller press hydraulic cylinder mainly outputs linear motion and force. The roller press hydraulic 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 roller press hydraulic cylinder, plunger roller press hydraulic cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger roller press hydraulic cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.
When installing the roller press hydraulic cylinder pipe, the pipe should be cleaned after installation, and should not pass through the roller press hydraulic cylinder block, and the by-pass pipe must be installed in front of the oil port of the roller press hydraulic cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the roller press hydraulic cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the roller press hydraulic cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.
The viscosity of the working oil used in the roller press hydraulic cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.
What is a hydraulic cylinder assembly?
Assembly, which means aggregate. A series of parts or products, formed to achieve a specific function of the whole, the general term for this system is assembly. The hydraulic cylinder assembly is not a single hydraulic cylinder part, which can be used by connecting the hydraulic hose.
Loader arm fell badly, how to know which oil cylinder is leaking?
No matter which cylinder leakage the arm will drop, it is best to replace the oil seal, even if one cylinder is good, it will not last long, and it will drop the arm, so the two cylinders should be replaced at once.
