1. For open or semi open centrifugal pumps arranged, a pump to pump the axis of the motor and the pipe gallery axis perpendicular to the.
2. For the indoor layout of the pump, when the liquid temperature is higher than the transmission of spontaneous combustion point or liquid hydrocarbons, and other pumps should be arranged in their respective rooms, and separated by a firewall.
Single stage single suction centrifugal pump is arranged in the room, generally do not consider the traffic requirements of motor vehicle maintenance, the net distance between the pump side or pump side and the wall should not be less than 1.2~1.5m, the net distance between the two rows of the pump is not less than 2m.
3. The installation dimensions of the equipment layout, the axis of the pump unit and the center line of the outlet flange as the datum. The elevation of equipment is expressed by the elevation of the bottom surface of the base of the self priming sewage pump. Note: the engineering company system professional calculation NPSHa is based on the pump's top surface as the standard, not the pump inlet center line elevation. The pump NPSHa is to import the center line of the pump as the standard, the difference between the center height of the pump.
4. Pumps should be arranged orderly, recommended to the center line of discharge pump even.
5. Electrical professional and technical or professional should be timely coordination, in the possible, the pump motor parts should be as far as possible in the explosion-proof area, to save investment.
6. Pump should be as close as possible to the liquid supply equipment, to prevent small NPSHa
7. The power side of the steam reciprocating pump and the pump side should be left out of the location of the piston and pull rod.
8. Vertical pumps do not know the bottom of the pipe gallery or below the frame, the top should be set aside pump installation and maintenance of the space required.
