Four-roller bending machine as a popular bending machine on the market, many customers buy four-roll bending machine do not know how to use, the following Chuangtu Machinery Technology will talk about the four-roll bending machine before the test run must be carefully checked which items: the following items must be carefully checked before the test:
1.Whether the pipeline connection and electrical wiring of each component are correct, firm and reliable, such as the inlet and outlet positions of pumps and valves, pipe joints, etc.
2.Whether the suction pipe joint of the pump is tightened, if it is too loose, it will cause lubricating oil or air absorption, and if it is too tight, the sealing performance will be deteriorated.
3.For oil injection, pay attention to whether the grade of the oil in the oil tank and the height of the oil level meet the requirements.
4.Whether there is dirt into the fuel tank, there should be a safety protection device.
5.Parts that need to be lubricated should be filled with the specified oil or grease.
6.Determine the running direction of the motor: generally refer to the direction of the arrow on the nameplate on the top of the hydraulic pump and the assembly drawing of the hydraulic equipment to check the running direction of the motor. Special requirements should first disconnect the coupling between the motor and the oil pump, and then the motor should be operated separately to determine the direction of rotation of the motor.
After reading the above points, I believe you should know what are the preparations before the test run of the four-roller rolling machine, and I believe that the four-roller rolling machine will be very convenient for customers to use!
