How to install and pay attention to the booster pump?

Butt line and fixed pump
1, ready to annex. In order to facilitate the installation, commissioning and maintenance of the booster pump, the pipe valve accessories should be prepared, the specific name, quantity and use are as follows:
Valve * 2, each with a valve in the water, in order to repair and debug. There is no pressure control device installed, the water inlet and outlet valve can also adjust the flow and pressure.
Flexible soft ground * 2, the import and export of water each with a soft, in order to prevent the processing pipeline error caused by the installation of difficult, but also can be convenient for the maintenance of the back of the dismantling machine.
Y type filter * 1, attached to the water inlet of the booster pump, prevent the impurities into the water pump pump damage.
The pressure gauge is 2, in which the water inlet and outlet are filled with a water inlet pressure gauge is designed to observe the water source and the water outlet pressure gauge is designed to observe the pressure of the water.
A * 2 flange or the pump flange, butt for flange connection, threaded connection for slipknot pump docking.
Flange gasket for flange connection sealing.
Screw for flange connection fastening.
One way valve * 1, if it is automatic booster pump, you do not need to prepare a one-way valve. Check valve to prevent backflow of water into the water outlet.
2, start docking pipeline. The attachment is ready, just need to follow the following diagram turn from being connected to the water outlet pipe. Pay attention to the direction of water inlet and outlet is not installed.
How to install and pay attention to the booster pump?
Two, motor wiring
1, automatic booster pump. If your booster pump has been brought with the automatic control device, generally only need to follow the instructions of the drawings connected to the external power supply + ground to the control box corresponding to the port, the motor line is generally have received good. If the signal line is split, then the pressure sensor signal line should pay attention to the order, the order of the feedback signal can not be correctly. Pressure transmitter wiring is relatively simple, generally red line is connected to the power supply terminal 24V, black ACI can be. Remote pressure gauge has three lines (10V, public power supply terminal, signal feedback), because each remote pressure gauge order is not necessarily the same, there is no detailed remote pressure gauge connection, if you have this need, you can consult our.
2, non automatic booster pump. If you only need a booster pump to manually start up, the connection is also very simple. Only need to use high-quality standard four core copper wire in accordance with the correct access method (motor junction box inside the diagram) received motor junction box inside. Single phase to the zero line and the line of fire to the corresponding position, do not need to change the wiring column. The three-phase motor, if the power is less than 2.2Kw, using the Y connection; power >2.2Kw, using delta connection method. Motor junction boxes are marked.
Three, the fixed anchor screw pump.
If there is no pre buried, need to be installed after the pump with the impact of drilling holes with the expansion screws can be used.
