(Turkmenistan roller press hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）
roller press hydraulic cylinder are widely used in Turkmenistan，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed roller press hydraulic cylinder for customers from Turkmenistan.
When the roller press hydraulic cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the roller press hydraulic cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the roller press hydraulic cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.
How to determine the working pressure of the roller press hydraulic cylinder: The pressure depends on the load size (i.e., F) and the type of equipment. The limitations of assembly space, economic conditions and component availability of the actuator should also be considered. In the case of a certain load, it is necessary to increase the structural size of the actuator if the working pressure is low, for some equipment, the size may be limited, and it is not economical from the point of view of material consumption; On the contrary, if the pressure selection is too high, the material, sealing and manufacturing accuracy of the pump, roller press hydraulic cylinder, valve and other components are also required to be high, which will inevitably increase the cost of equipment. In general, for equipment with a fixed size that is not too limited, the pressure can be selected lower, and the walking machinery should be selected higher.
When the piston speed of the roller press hydraulic cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the roller press hydraulic cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.
Before the roller press hydraulic cylinder is removed, the system should be unloaded, the loop pressure is zero, the oil source should be cut off, and the oil port should be blocked after the oil port distribution pipe is loosened.
How to calculate the tonnage of the hydraulic press? Example: The input cylinder pressure is 5Mpa, the end area of the cylinder piston is 100mm, and how much is the thrust tonnage?
F=P*S=5*10^6*3.14*(1/20)^2=39250N.
What is the difference between hydraulic piston cylinder and plunger cylinder?
The force surface of the piston cylinder is a rod cavity and a rodless cavity, and the force surface of the plunger cylinder is the plunger, the spring return single-acting piston cylinder can also rely on the external force of the spring to achieve return, the double-acting piston cylinder can produce tension, and the plunger cylinder only produces thrust without tension.
