Possible faults and their troubleshooting methods
|
Trouble |
Shooting |
Methods for fault causes |
|
turn on electricity The solenoid valve cannot be opened. |
The power supply voltage is too low Burnout of coil the medium pressure is too low |
Adjust the voltage to within the range of use Replace the coil Increase the pressure of pipeline medium |
|
Turn off power The valve cannot be closed or closes poorly |
The medium pressure is too high Membrane damaged or foreign object stuck Tower spring deflection above the diaphragm |
reduces the pressure of the pipeline medium Replace with a new diaphragm to remove foreign objects Repositioning installation |
Installation instructions:
1. When installing, the solenoid valve coil should be facing upwards and kept in a vertical position. The arrow or mark on the solenoid valve should be consistent with the flow direction of the pipeline and should not be installed in areas with splashes or leaks.
2. The working medium of the solenoid valve should be clean and free of particulate impurities. The dirt and filters on the surface of the solenoid valve components should be regularly cleaned.
3. When the solenoid valve malfunctions, it is best to install a bypass device in order to isolate the solenoid valve in a timely manner and ensure the normal operation of the system.
4. In pipeline systems, the diameter of the solenoid valve installed on the branch should be smaller than the diameter of the main pipeline valve.
5. Before installing the solenoid valve, the pipeline must be cleaned thoroughly. It is recommended to install a filter in front of the valve and a drain valve in the steam pipeline.
6. Valves should not be installed in the low recesses of the pipeline to prevent steam condensation, impurities, etc. from settling inside the valve and hindering its operation.
7. The ordinary type cannot be used in explosive hazardous situations.
8. In the case of insufficient pipeline rigidity, it is recommended to fix the pipeline in front of the valve with a bracket to avoid vibration caused by the operation of the solenoid valve.
9. Before installation, it is important to carefully read the product label, carefully read the user manual, and determine whether the product meets the conditions for use.
10. Pressure gauges need to be installed on the front and rear pipelines of the solenoid valve to observe the pipeline pressure.
Instructions for use and maintenance
1. It is recommended that the using unit assign a dedicated person to be responsible for the use and maintenance.
2. After the installation of the solenoid valve, it is necessary to conduct several experiments with the medium and confirm that it is normal before it can be put into formal use.
3. Regularly clean the dirt inside and outside the large valve, as well as the suction surface of the armature. Be careful not to damage the sealing surface.
4. When the solenoid valve is not used for a long time, the manual valve in front of the valve should be closed. When it is reactivated, the steam solenoid valve should drain the condensate clean and perform several trial actions. It can only be put into use after the switch is normal.
5. When the solenoid valve is removed from the pipeline and not in use, the internal parts should be wiped clean and stored with compressed air.
6. When used for a long time, if the seal between the piston and the valve seat is not good, the sealing surface of the piston can be ground flat again, and then ground with the valve seat.
7. When working, attention should be paid to the pressure gauges before and after the valve. The working pressure should not exceed the rated pressure, and the working pressure difference must be within the range of the rated pressure difference. When the working pressure exceeds the rated pressure or the working pressure difference exceeds the rated differential, the solenoid valve should be stopped and the front and rear manual valves should be closed to prevent the solenoid valve from exploding and leaking.
Ordering Notice
1. Please indicate the model, nominal diameter, nominal pressure, working medium, working pressure difference, medium temperature, power supply voltage and frequency, and medium viscosity when placing an order.
2. The voltage of the solenoid valve during normal operation is 220V. If it exceeds this range, please indicate the voltage fluctuation when placing an order. Other specifications of power supply voltage can be specially ordered.
3. If the opening time of the valve is more than 12 hours, please choose a normally open solenoid valve. When there are flammable and explosive materials in the surrounding environment, please choose explosion-proof solenoid valves
When the usage situation is very important or the environment is complex, please provide design drawings and detailed parameters as much as possible, and our experts from Fengquan Company will review and control it for you.
