JB/T6273.1—92
This standard specifies the type, model and basic parameters of small rural drinking water equipment (hereinafter referred to as drinking water equipment). This standard applies to drinking water equipment with motor and water pump integrated, flow rate less than 3m/h, ground head 4~12m, suction head (suction head refers to the vertical distance from the underground dynamic water level to the center line of the pump impeller) 6~20m, and matching motor power of 750W and below. 2 Reference Standards
JB/T6273.2 Technical Conditions for Small Rural Drinking Water Equipment3 Types
3.1 Drinking water equipment is divided into two types: automatic operation type and non-automatic operation type. The automatic operation type is composed of a water pump, a motor, a jet pump, a pressure tank and an automatic control system. 3.1.1
3.1.2 The non-automatic operation type is composed of a water pump, a motor and a jet pump. 3.2 Water pumps are divided into centrifugal and vortex types according to the impeller type. 3.3 From the water pump impeller suction population, the pump shaft rotates counterclockwise. 3.4
The water pump and the motor of the drinking water equipment are coaxially connected. 4 Model
