Use The Corresponding Explosion-proof Motor
- Apr 23, 2018 -

According to pump selection principle and basic conditions for selection, the specific operation is as follows:

1. According to the layout of the device, terrain conditions, water level conditions, operating conditions, determine the choice of horizontal, vertical and other types (pipeline, submersible, submerged, non-clogging, self-priming, gear, etc.) pumps.

2. According to the nature of the liquid medium, determine the clear water pump, heat pump or oil pump, chemical pump or anti-corrosion pump or impurity pump, or use non-clogging pump. Pumps installed in explosive areas should be equipped with explosion-proof motors according to the level of the explosion zone.

3. According to the flow rate, determine whether the menu suction pump or double suction pump; according to the level of lift, single-stage pump or multi-stage pump, high-speed pump or low-speed pump (air-conditioning pump), multi-stage pump lower efficiency than single-stage pump, such as the menu level When a pump and a multi-stage pump can all be used, first, a single-stage pump is used.

4. Determine the specific model of the pump

After determining which series of pumps are selected, the maximum flow rate, (in the absence of maximum flow, normally 1.1 times the normal flow rate can be taken as the maximum flow rate), the two heads of the lift after amplification of 5%-10% margin can be taken. The main parameters, in the spectrum or series of characteristics to determine the specific model.
