The hydraulic cylinder manufacturer analyzed the cause of the hydraulic cylinder seal damage

      Although the hydraulic cylinder is usually inaccessible, it is an important part of the mechanical equipment. If the hydraulic cylinder seal is damaged, it will affect the normal operation of the equipment, so you try to choose a brand with reliable quality.In order for users to avoid the phenomenon of hydraulic cylinder seal damage, Zhejiang hydraulic cylinder manufacturers have found out the reasons for everyone, and if you are interested, let's take a look.

Hydraulic cylinder

The study found that when the profiling tool holder is in place, the tool holder is affected by the overall impulse f'.After decomposition, the horizontal thrust f'1 acts on the piston rod of the longitudinal cylinder.At the same time, the solenoid valve works, the longitudinal cylinder has a connecting rod chamber connected to pressure oil, and the connecting rod chamber is connected to speed regulation.In the valve oil return circuit, the piston rod cavity force F is completed by two parts, namely the force-bearing area of ​​the rodless cavity.

Generally, the piston moves to the rodless cavity under the action of the force F. Because the hydraulic oil is not compressible, the pressure of the hydraulic oil in the rodless cavity rises sharply, forming the back pressure of the piston, and the force balance of the piston is based on the speed control valve.Due to the effect of F, the P2 pressure in the longitudinal cylinder chamber will be greater than the P1 pressure at this time.

In fact, due to the gap between the two chambers of the cylinder, at the moment p2>p1, the hydraulic oil has a tendency to flow from the rodless cavity in the high pressure area to the rodless cavity in the low pressure area.Once flow occurs, p2 decreases, p1 increases, and F1 increases. The piston force loses balance, and the piston drives the tool holder to move quickly to the rodless cavity.After an instant, as the downward movement of the profiling tool post ends, the horizontal thrust f acting on the longitudinal cylinder piston disappears, the piston moves quickly, the tool post moves smoothly, and the stamping phenomenon ends.

The above is the reason for the damage of the hydraulic cylinder seal. Have everyone understood? In this situation, we need to find the corresponding solution according to the cause of the accident before we can proceed to deal with it.If you want to buy hydraulic cylinders, worm gear box reducers, worm gear boxes and other products, you can call us Jinyun Boxin Machinery.
