Welping's rolling groove machine in helping customers in the metal pipe pressure groove played a vital role, by the customer's widely praised, but there are a small number of customers in the use of the process encountered a little problem, in line with the serious and responsible attitude, we made for the customer's technical guidance, exclude the problem.
One of the more representative questions is why there is no pressure in the cylinders of the groove rolling machine.
Firstly to answer this question, one needs to understand what a hydraulic cylinder is.
In the 17th century Pascal proposed the principle of hydrostatic transmission of liquids, which laid the foundation for the later development of hydraulic cylinders. Hydraulic cylinder is the hydraulic energy into mechanical energy, to do linear reciprocating motion or oscillating motion of the hydraulic equipment, it is a simple structure, to do reciprocating motion, smooth movement, in a variety of engineering machinery widely used.
Hydraulic cylinders require hydraulic oil to function properly.
Hydraulic oil is the use of liquid pressure energy hydraulic system used in the hydraulic medium, in the hydraulic system plays a role in energy transfer, anti-wear, system lubrication, corrosion, rust, cooling and so on.
Although Welping's groove rollers attach great importance to the sealing of their hydraulic cylinders, as the hydraulic oil needs to be replaced regularly, the inlet for replacing the hydraulic oil is reserved, and when replacing the hydraulic oil, not enough is added or the inlet is not screwed in tightly, resulting in insufficient hydraulic oil, and the problem can be solved by adding enough hydraulic oil.
Secondly, if the hydraulic oil is not replaced for a long time, it will become dirty, resulting in the blockage of the orifices, which will also cause this phenomenon, and timely replacement of the hydraulic oil can be solved.
And finally, there is the possibility that the check valve mating surface is leaking.
One-way valve is to rely on the flow of the medium itself and automatically open and close the valve flap, used to prevent the medium backflow valve, the role of the one-way valve is to allow the medium to flow in one direction only, and to prevent the flow of the opposite direction.
So you can contact our factory technicians who can guide you on how to do the repairs.
The above are the three possibilities and solutions that may cause no pressure in the hydraulic cylinder of the rolling groove machine, I hope it can help all users.
