How to ensure the precision of hydraulic pipe bending machine

Everyone's hydraulic pipe bending machine uses an electric motor to drive the hydraulic oil pump and input hydraulic oil, and uses a vacuum solenoid valve to input steam pressure driving force to bend the pipe fittings. However, how can the hydraulic transmission system improve and ensure the accuracy of the pipe bending? This is also a question that everyone must consider.

Anyone who has done or touched the hydraulic transmission system knows that hydraulic oil in people's hydraulic pipe bending machines will increase in oil temperature through long-term operation. When the oil temperature increases, manipulating the vacuum solenoid valve will cause the oil to not close tightly, or the hydraulic oil input will be uneven, resulting in significant damage to the accuracy of the pipe bending. For such problems, we can use servo motors to control the angle of view of the pipe bending. However, due to the increase in oil temperature, the oil cannot be tightly shut off, resulting in the inability to clamp and deviation during bending. After slipping, the pipe fittings will wrinkle or deform when bent. That greatly endangers the quality of bent pipes. But how should we deal with this kind of problem?

Everyone's hydraulic pipe bending machine uses a main oil tank, and the oil injected into the steam pump needs to pass through the cooling tower and then return to the inside of the oil tank. We can insert two tap water pipes into the cooling tower and apply drinking water circulation system to reduce temperature, which can effectively reduce oil temperature. Further maintain the hydraulic pipe bending machine to reduce the accuracy of the bending process due to the increase in oil temperature.
