Canada hydraulic cylinder,pusher hydraulic cylinder manufacturer,pusher hydraulic cylinder
(Canada pusher hydraulic cylinder,produced by Hebei Hengyu company）
pusher hydraulic cylinder are widely used in Canada，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed pusher hydraulic cylinder for customers from Canada.
pusher 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 pusher 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 ' pusher 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 pusher hydraulic cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The pusher hydraulic cylinder mainly outputs linear motion and force. The pusher 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 pusher hydraulic cylinder, plunger pusher hydraulic cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger pusher hydraulic cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.
In order to ensure the service life of the pusher hydraulic cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the pusher hydraulic cylinder, causing damage to the seal and causing leakage in the pusher hydraulic cylinder. It is required that the filtration accuracy of the system is not less than 80μm, the oil pollution is strictly controlled, the hydraulic oil is kept clean, the performance of the hydraulic oil is regularly checked, and the necessary fine filtration or replacement of the new working hydraulic oil is carried out.
The difference between the integral pusher hydraulic cylinder and the split pusher hydraulic cylinder: The integral pusher hydraulic cylinder and the split pusher hydraulic cylinder in the pusher hydraulic cylinder are two different pusher hydraulic cylinders, and they are very different. The whole pusher hydraulic cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split pusher hydraulic cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and pusher hydraulic cylinder damage. Therefore, it is obvious that the answer to this question is for difference.
When the long-stroke pusher hydraulic cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in pusher hydraulic cylinder head seal damage, oil leakage, and piston sleep in the pusher hydraulic cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle and process it into a convex drum, so that the piston can self-position, improve the force situation, and reduce and avoid pulling the pusher hydraulic cylinder; The piston and the piston rod are connected with a spherical joint.
Why does the cylinder pop out of itself when it stops?
This situation has two possibilities, 1. There is more air in the system, so exhaust the gas. 2. The back pressure of the oil return is relatively large, check the oil return filter, check whether the cylinder has a rod cavity buffer is too tight, and choose a 3-position 4-way M-type valve for the reversing valve. In addition, after the shutdown, manually change the reversing valve back and forth several times, it should not rise out.
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.
