As we all know, the main power of cnc pipe grooving machine is the hydraulic oil pump input hydraulic oil, and rely on the hydraulic solenoid valve to provide control hydraulic power to the cylinder piston to achieve the operation of each part. Under normal circumstances, the oil temperature should be set at 90°, but after the oil temperature rises, there will be a deviation of 100° or 70°. How should we solve this situation?

The oil moves back and forth in the oil pump motor, and achieves high pressure input through the electromagnetic valve push, in this mode, soon our oil temperature will rise, especially in the hot summer, all kinds of pipe bending machines, including automatic cutting metal circular saw machine and pipe shrinking machine will appear, the oil seal will not be sealed resulting in the oil outlet on the pipe cutting machine to decline, and the pressure of the pipe shrinking machine will be insufficient. The bending Angle error of the pipe bender is very large.

This method is certainly cumbersome, unless it is not usually necessary. The best way is to add some hydraulic oil when summer comes, and shut down the cnc pipe grooving machine when it is not running.

The cnc pipe grooving machine works for 8 hours a day, and generally this problem does not occur, but if this happens, it can be dealt with in the above way.

To determine the working time of the cnc pipe grooving machine, turn it off as far as possible in the case of unmanned operation, so that the hydraulic motor stops running, and detect whether the hydraulic oil in the hydraulic cylinder is sufficient. When summer comes, some hydraulic oil should be added appropriately, as long as the oil is sufficient, the oil temperature will not rise quickly. It is also possible to insert a pipe into the cooling pump to achieve water circulation cooling.
