Damping method and parameter adjustment of pump truck       

Pump vibration principle belongs to active tracking pump switching frequency to pressure compensation period of a support cylinder arm, realize vibration quantity, the vibration control technology has international patents, by testing and site actual performance, can greatly reduce the amount of vibration, are of great help to improve the pump work safety and fatigue life. The system starts automatically after the pump displacement is greater than 50%, but you can close the ball valve according to the production needs to determine whether to use the vibration control system.

Usage method：

1. the boom started, ensure the compensation cylinder joints have a certain angle (less than 170o), the 37 m pump by compensating cylinder No. 2 arm cylinder, 45 meters, 48 meters for the No. 3 pump truck boom cylinders, 56 m pump No. 4 arm cylinder;

2. in the pump operation, please close the valve control system;

3. in general, in order to save energy storage energy, reduce vibration control device wear, when the small displacement pump or high pumping, the system can be closed;

4. if large displacement horizontal pumping, boom end vibration will be larger, you can choose to open the vibration control system, in general, the vibration situation will be effectively alleviated;

5. if the ball valve is opened, the vibration will be increased. Please adjust the phase angle according to the following way, until the vibration reaches the best level, and the general power supply time need not be adjusted;

6. if the adjusted parameters, please set parameter information feedback to the new service through mobile phone short message

7. adjustment must be in remote control state, at this time the control panel all buttons including the horn button are invalid, so please adjust as soon as possible, do not affect the use.

Parameter adjustment method (careful adjustment):

PLC system debugging method: at the same time pull the "master cylinder" and "pendulum cylinder into" switch, enter the vibration parameters of the arm, adjust the interface, according to 'F7' exit, and permanently preserve the boom vibration parameters. Under the parameter adjustment screen: according to "stir inversion", the T value increases, according to "positive pump", the T value decreases; according to "anti pump", the N value increases; according to "high pressure", the N value decreases. In general, the N value is adjusted only.

Advantage：

At the same time to reduce the amount of vibration of the boom stress state is improved, compared with the original system significantly reduces stress. Pump operation personnel can be more relaxed, more secure operation at the end of the hose.
