(Norway hydraulic cylinder for vehicles,produced by Hengyu Hydraulic Co., Ltd）

hydraulic cylinder for vehicles are widely used in Norway，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed hydraulic cylinder for vehicles for customers from Norway.

Introduction to hydraulic cylinder for vehicles:

hydraulic cylinder for vehicles abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the hydraulic cylinder for vehicles is placed for a period of time, the hydraulic cylinder for vehicles may enter the air, and the movement can be normal after dozens of repeated movements. If it still cannot be eliminated, check whether the load is aligned with the axis of the piston rod; Retracted piston rod installation helps to align the load with the piston rod. If the flow is unstable, it will also lead to abnormal movement of the piston rod. Check the relevant components of the hydraulic system.

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

Do not enter foreign bodies when installing the hydraulic cylinder for vehicles block. The place where the installation operation is carried out, the conditions are not good, and foreign bodies can be entered unconsciously. Therefore, the installation site must be cleaned up around, especially the place where the parts are placed must be cleaned, so that there is no dirt.

hydraulic cylinder for vehicles buffer valve inspection and maintenance: For the valve buffer hydraulic cylinder for vehicles, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.

Answers to some questions about hydraulic cylinder for vehicles:

How big is the pump and motor for 20 tons of hydraulic cylinder?
According to the working pressure of 25 mpa estimate, the cylinder should use 100mm bore, 63mm piston rod, stroke 40mm. According to 30 reciprocating calculation, the flow rate is about 25 liters/minute. The motor power is 11 kW, want to be cheap, use 25SCY14-1B oil pump can be.

How to remove the air in hydraulic cylinder?
Connected the cylinder to the system, and reciprocating move with full stroke several times, then the air can be eliminated . There is also a clunky method as follows: first remove the rod cavity oil pipe, connect the rodless cavity oil circuit to extend all the cylinders, and then remove the rodless cavity oil pipe, connect the rod cavity oil pipe and withdraw all the cylinders, and then connect the rodless cavity oil pipe, so that there is no air in the cylinder.
