Press can be divided into hydraulic high-pressure pipe press, brake pipe press, air-conditioning pipe press, power pipe press and so on. According to the mechanical structure, it can be divided into straight cylinder press, double column press, open press and C-type press, and according to the control mode, it can be divided into electromechanical press, PLC press and CNC press. The usage method is as follows:
1. Fill 50kg hydraulic oil once;
2. Locator installation: firstly, insert the locator into the front end of the machine head, and insert the plug at the other end into the corresponding socket in the electrical cabinet;
3. Connect the power supply. If a three-phase motor is used, be careful not to connect the reverse rotation;
4. After the above process is completed, start the pressure test;
5. Use of positioner: press in 65,438+0 mm more every half cycle in reverse direction, press in 65,438+0 mm less every half cycle in forward direction, and so on. Rubber hoses and joints of the same specification have reached the required pressure, and it is not necessary to move the positioner. The compressed data of this specification is completely consistent. When you tested the first oil pipe, you had learned the rest.
High-pressure tubing is an integral part of high-pressure oil circuit, which requires tubing to bear certain oil pressure and have certain fatigue strength to ensure the sealing requirements of the pipeline. Vehicle high-pressure tubing mainly appears in high-pressure injection diesel engines and high-pressure injection direct injection gasoline engines, which can withstand the oil pressure required for engine operation.
