PC300-7 Rotary motor relief valve 702-77-02120 excavator accessories

The electromagnetic valve of the excavator plays a controlling role.

1, solenoid valve is an industrial equipment controlled by electromagnetic, is used to control the basic components of fluid automation, belongs to the actuator, not limited to hydraulic, pneumatic. Used in industrial control systems to adjust the direction of media, flow, speed and other parameters.

2, the solenoid valve can be combined with different circuits to achieve the desired control, and the accuracy and flexibility of the control can be guaranteed. There are many kinds of solenoid valves, different solenoid valves play a role in different positions of the control system, the most commonly used are check valves, safety valves, direction control valves, speed regulating valves and so on.

If the solenoid valve is broken, there will be obvious manifestations and symptoms, such as the gearbox will make a noise, there will be a feeling of frustration when upshifting and downshifting, the fuel consumption of the vehicle will become more, the vehicle is difficult to start when it is cold, and there will be a lack of power when driving.

The method and symptoms of whether the solenoid valve is damaged:

1, judging by the smell of the car, there is a large smell of gasoline in the car, which may be the solenoid valve is damaged;

2, the vehicle is in the idle state, the engine speed appears for a while high and low, indicating that the solenoid valve may be damaged;

3, when the vehicle accelerates, there will always be a crash situation, which affects the driving experience, and it is necessary to check the carbon tank battery valve in time;

4, the vehicle instrument panel lit up the transmission failure light, it may be the shift solenoid valve failure. The identification of the gearbox fault light is a gear and an exclamation mark, and the exclamation mark is inside the gear;

5, the vehicle will be stuck when switching gears, or it can not change gears.
