Argentina hydraulic cylinder,flanged hydraulic cylinder manufacturer,flanged hydraulic cylinder
(Argentina flanged hydraulic cylinder,produced by Hebei Hengyu company）
flanged hydraulic cylinder are widely used in Argentina，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed flanged hydraulic cylinder for customers from Argentina.
Most of the failure of the flanged hydraulic cylinder is because there is a foreign body in the flanged hydraulic cylinder into the failure of the flanged hydraulic cylinder, the most problematic is that it is difficult to determine when the foreign body is into the flanged hydraulic cylinder. After a foreign body enters, if the outer side of the sliding surface of the piston is equipped with a seal with a lip edge, then the lip edge of the seal can scrape the foreign body when working, which is beneficial to avoid scratching. However, the piston equipped with 0-shaped sealing ring has a sliding surface at both ends, and foreign bodies are sandwiched between this sliding surface, which is easy to form scars.
When installing the flanged hydraulic cylinder, the axial ends of the flanged hydraulic cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the flanged hydraulic cylinder, there is axial expansion. If the two ends of the flanged hydraulic cylinder are fixed, all parts of the flanged hydraulic cylinder will be deformed. When disassembling the flanged hydraulic cylinder, it is strictly forbidden to hammer the flanged hydraulic cylinder and the piston surface, such as the flanged hydraulic cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.
The flanged hydraulic cylinder requires that the filtration accuracy of the system is not less than the 80um, and the oil pollution should be strictly controlled, the oil should be kept clean, the performance of the oil should be checked regularly, and the necessary fine filtration and replacement of new working oil should be carried out.
The piston rod of the flanged hydraulic cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.
How to make 4 cylinders balance lifting weight at the same time?
The cost of the synchronous valve is lower, 4 cylinders need 3 synchronous valves, to be precise you can use a synchronous motor, but it is more expensive. There is another way, that is to install a throttle valve in each cylinder, respectively adjust the speed of the cylinder.
What are the connection methods of the hydraulic cylinder? The connection modes of the cylinder and the actuator are earring connection, hinge shaft connection, thread connection, etc. The connection modes of tubing and cylinder are threaded connection, flange connection, etc.
