Proportional Solenoid Valve Excavator Parts SV98-T40

1. After the hydraulic one-way valve is broken, there will be many failures that the system cannot work;

2. Because the mechanical equipment is stopped for a long time, it may lead to the deterioration of hydraulic oil, which may easily lead to pipeline leakage and lose its protective effect, or even cause explosion. At this time, it is necessary to repair and replace the hydraulic motor;

3. When there is no actuator in the safety circuit or no anti-freezing measures are taken in the electronically controlled cylinder, the cooling system will leak seriously at the extreme temperature, and the temperature of the hydraulic station will exceed 100℃-140℃, so the machine may be damaged, and it will be difficult to repair if it cracks in large quantities;

4. When the piston is extended, it is connected with oil and reversed when it is in position, which will produce abnormal force or make a noise in vibration;

5. When the hydraulic system is turned on, the piston rod (column) is bent due to the stress of each part, which will damage the seal and cause leakage.

6, hydraulic check valves, they make the actuator unable to reverse and reverse, that is to say, the opening and closing of the check valve has lost its control function;

7. The phenomenon of accelerated wear of the contact surface of the electro-hydraulic commutator due to sticking or sticking, and the serious internal and external leakage can lead to the hydraulic oil temperature rising too high and the hydraulic one-way valve being quickly damaged;

8. If you usually work for a long time or often operate the machine under the condition of large vibration, it is easy to cause poor pressure resistance of the hydraulic hose, which will affect the safety and life, or make the exhaust pressure too high, which is not conducive to the pressure adjustment required by the working conditions;
