How To Prevent Angle Deviation Caused By Oil Temperature in Bent Pipes

We all know that hydraulic pipe bending machines rely mainly on hydraulic oil pumps to input hydraulic oil, which is controlled by hydraulic solenoid valves to provide hydraulic power to the cylinder pistons and achieve the operation of each part. Originally set at 90 ° under normal circumstances, but when the oil temperature increases, there may be deviations of angles such as 100 ° or 70 °. How can we solve this problem.

The hydraulic oil runs back and forth in the oil pump motor, and then pushes through the solenoid valve to achieve high-pressure input. In this mode, our oil temperature will quickly rise, especially in the hot summer, various pipe bending machines, including metal circular saw machines, fully automatic pipe cutting machines, and pipe shrinking machines, will experience oil leakage that cannot lock the oil, resulting in the head of the pipe cutting machine falling, insufficient pressure in the pipe shrinking machine, and significant bending angle errors in the pipe bending machine.

This is of course quite troublesome, unless it is generally not necessary in special circumstances. The best method is to add some hydraulic oil appropriately during the summer and turn off the machine when the hydraulic pipe bending machine equipment department is operating.

Our hydraulic pipe bending machine works for 8 hours a day, and under normal circumstances, such problems do not occur. However, if these situations occur, the above methods can be used to solve them.

We should determine the working time of the hydraulic pipe bending machine, try to turn it off when there is no one operating it, stop the hydraulic motor, check the hydraulic oil tank, and add hydraulic oil if there is enough or insufficient hydraulic oil. When summer comes, we should add some hydraulic oil appropriately. Only when there is enough hydraulic oil can the oil temperature not rise so quickly We can insert a water pipe into the cooling pump on our pipe bending machine equipment to achieve water circulation and cooling.
