Preventive measures for common failures of automatic valves and energy-saving working principles of frequency conversion water pumps

1. Preventive measures for common failures of automatic valves:

a) Regularly check and clean the water inlet filter, and replace it regularly.

b) Check the pressure difference of the valve, the working pressure difference should not be too large.

c) Check the seal of the valve, whether the sealing surface is intact.

d) Check whether the actuator has water leakage, if there is water leakage, it needs to be replaced in time.

e) Check whether the electric contact of the valve is normal, and replace the damaged parts in time.

2. Energy-saving working principle of frequency conversion water pump:

The energy-saving working principle of frequency conversion water pump is to adjust the flow rate and pressure of the pump according to the actual needs of the system. When the system needs less water, the frequency converter can adjust the speed of the pump to reduce the flow rate and pressure, so as to achieve the purpose of energy saving. When the system needs more water, the frequency converter can adjust the speed of the pump to increase the flow rate and pressure to meet the needs of the system.

a. The frequency conversion water pump is a variable frequency water pump that can adjust its output power according to the external water pressure and volume. The working principle is to change the frequency of the power supply to change the speed of the motor and the flow rate of the pump.

b. When the water pressure is low, the pump can reduce the speed or output power, thereby saving energy. When the water pressure is high, the pump can increase the speed or output power, so as to meet the water demand.

c. The use of frequency conversion technology can reduce the starting current of the pump, reduce the impact on the power grid, and improve the stability of the power grid.
