In the hot summer, it is the peak period of water pump usage. How to use water pumps and what issues should be paid attention to in order to reduce energy consumption and save costs? Today, the editor of MT3 1221 Water pump will take you to find out.
1. The surface of the pump and the inner surface of the pressurized water chamber (also known as the volute) are rusty and uneven
The rusty and uneven surface will reduce the pump water volume by 7%-8%; only need to use a steel brush and iron sandpaper or grinding wheel to smooth the pump, you can reduce the fuel consumption or power consumption during work by 9%-14%.
Second, the gap of the seal ring is increased

According to inspections, when the gap in the radial direction of the impeller is increased by 4 mm, the water volume of the pump will be reduced by 10%; only need to use organic adhesive and asbestos thread to restore the gap to the factory-specified gap during maintenance, and the fuel consumption or Power consumption is reduced by 10%-12%.
3. The axis of the pressurized water chamber and the impeller do not coincide
According to the test, when the axis of the pressurized water chamber and the impeller deviate by 2 mm or the deflection angle is greater than 2 degrees, the water volume of the pump will be reduced by 5%-6%; during maintenance, only need to measure carefully, carefully locate the position where the axis coincides, and install it firmly. It can reduce the oil or electricity consumption of the pump by 6%-7% during operation.
The above is the editor of MT3 1221 Water pump: a brief introduction to the little knowledge about water pumps in summer to reduce energy consumption and save costs.
