CNC Hydraulic Pipe Bender System Oil Discharge and Refueling Instructions


1 min read

The development process of the pipe bending machine in China has gone through several stages: the first stage mechanical structure, which began to produce the pipe bending machine in China in the 1950s and 1960s, but it was driven by a cam or a large gear transmission. The block mold, in order to achieve the bending process of the sheet, it is conceivable that the machine is low in efficiency, high in noise, and the bending force generated is greatly limited. Even so, this kind of manufacturing and use in China continues a lot. Year; the application of the second-stage hydraulic technology, in the early 1980s, with the gradual opening of China, foreign advanced manufacturing methods began to be introduced into China, and hydraulic technology was also applied.

Regular discharge of water and sediment from the tank is critical to removing impurities from the oil. At the same time, the oil in the entire hydraulic system must be vented periodically to completely remove system impurities, oxidized hydraulic fluid and other harmful effects. substance. Once completed, the clean hydraulic pressure needs to be re-added to the system.

Because good hydraulic fluids contain a variety of additives that prevent oil from damaging or clogging system parts, after a long period of use, no one can guarantee its effectiveness, so it needs to be replaced regularly. In addition to draining and refueling, regular filter changes are also one of the measures to keep the hydraulic bender system clean in order to keep the system clean.

The main power is powered by the hydraulic system, so we have to introduce what the hydraulic system has. An oil circuit control board, also called oil circuit board, four or five sets of solenoid valves, each group of solenoid valves are controlled by an action unit. Generally, the four groups of clamping, core pulling, auxiliary pushing and bending are included. Because each part of the action is independent, a separate solenoid valve control is required. A set of pressure-retaining valves: The pressure-retaining valve is used for clamping. Because the pipe is bent, it will be subjected to expansion force. If there is no pressure-keeping valve to keep the oil pressure stable, the clamping will not be clamped, and the pipe will appear. Wrinkle deformation and so on.
