For the new equipment hydraulic pipe bending machine, the oil product problem has little impact on the noise of the hydraulic pipe bending machine, because the newly added hydraulic oil meets the requirements, and the noise may be caused by insufficient oil, resulting in the sound of the air inhaled by the oil pump, or the motor oil pump itself has fault, but the equipment used for a long time suddenly has abnormal noise, The problem of abnormal noise can be solved by checking the oil products and cleaning the oil tank and oil suction filter screen.
Pipe bending machine, pipe cutting machine, pipe shrinking machine and other pipe processing machinery are becoming more and more mature and stable in terms of quality and technology. We are not in a state of exploration because of the birth of a new product and new technology in the past, so the performance stability of the machine is relatively fragile, but today’s pipe processing equipment is stable and routine, Therefore, after purchasing the machine tool, as long as you carefully maintain the machine tool, it can be used for a long time.
In this way, when the pipe bending machine inserts the pipe into the mandrel, these small iron pins will fall out, and the iron pins that have not been cleaned will fall into the oil tank inside the machine body. We all know that the hydraulic pipe bending machine uses the oil pump to input the hydraulic oil and the solenoid valve to provide hydraulic power. Therefore, after entering the oil tank, most of these iron pins will be filtered by the filter screen in our oil inlet pipe, but a small part of the iron pins will enter the oil pump, so that the iron pins sucked into the oil inlet pump will enter the solenoid valve, and these iron pins cannot flow in the solenoid valve, resulting in the blockage of the hydraulic solenoid valve, The hydraulic oil cannot flow, so a corresponding action failure will occur, resulting in the failure of the hydraulic pipe bending machine. Even if this phenomenon occurs, there is no need to panic. Just press a certain action manually according to the keys on the control panel, look at the indicator light on the solenoid valve, see which solenoid valve doesn’t work, and then turn off the film. Then use a 4mm Allen wrench to remove the solenoid valve fixed on the oil separator. After cleaning the solenoid valve with clean kerosene, blow the inside with an air gun, clean the iron pin inside, and then install it.
But what problems often occur in daily use? In fact, these problems have been mentioned in the previous log technical articles. Today, we talk about the old saying that there are usually problems in the hydraulic area. When the machine bends the pipe, there will be many small iron pins left when the pipe is cut by the metal circular saw. If these iron pins are not cleaned, they can be directly taken to the pipe bending machine to process the pipe bending, and many automatic pipe bending machine molds are bent with mandrel. Because they are afraid that the fullness is not high enough, they will wrinkle or collapse.
