Our country’s pipe bender equipment is also mature and stable in terms of quality and technology for hydraulic pipe benders, automatic pipe benders, pipe cutting machines, and pipe shrinking machines. The birth of new products and technologies, we are all in a state of groping, so the performance of the machine is relatively fragile, but today’s pipe processing equipment is stable and routine, so after purchasing the machine tool, you only need to maintain it carefully. A good machine tool can be used for a long time.

But what problems often occur in daily use of pipe bending opportunities? Usually there is a problem with the hydraulic area, because when the machine is bending the pipe, the pipe is cut with a metal circular saw, which will leave a lot of small iron pins. If these iron pins are not cleaned up, they will be taken directly to the pipe bending machine to process the pipe. Many pipe bending machine molds have mandrels to bend, because they are afraid that the fullness is not high enough, they will wrinkle or collapse. And other phenomena.       In this way, these small iron pins will fall out when the pipe bender inserts the pipe into the mandrel, and the iron pins that have not been cleaned will fall into the oil tank inside the fuselage. We all know that the hydraulic pipe bender uses an oil pump to input hydraulic pressure. The oil relies on solenoid valves to provide hydraulic power. Therefore, after these iron pins enter the fuel tank, most of them will be filtered out by the filter 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 pump will enter the electromagnetic Inside the valve, and these iron pins cannot flow in the solenoid valve, causing the hydraulic solenoid valve to be blocked, and the hydraulic oil cannot flow. This will cause a corresponding action failure and cause the hydraulic pipe bender to fail to work normally.       Even if this phenomenon occurs, there is no need to panic. Just manually press a certain action according to the buttons on the control panel, and then look at the indicator light on the solenoid valve to see which solenoid valve is not working, and then close the movie. Then use a 4mm Allen key to remove the solenoid valve fixed on the oil separator plate. After cleaning the solenoid valve with clean kerosene, blow the inside with an air gun to clean the iron pins inside, and then install it to solve the problem.
