pipeline pump installation

Mention the pipeline pump, we may not unfamiliar, and now a lot of places can be applied to the pipeline pump, which we know how to install the pipeline pump? Shanghai Weihu pipeline pump manufacturers to introduce the specific content

1, the installation should be selected away from the transport of the nearest place, so that the Jinan pipeline installed in the minimum suction height and the shortest suction pipe

Note: should ensure that the unit and the surrounding obstacles more than 150 mm distance, so that the motor fan has access to adequate air source.

2, when the pump used in the more stringent requirements of the vibration, you can use the shock absorber (pad), according to the manufacturer's instructions to install.

3, the installation of the pipeline should be reliable fixed, close to the pump flange pipe support should be sufficient rigidity, not to allow the pump to withstand the weight of the pipeline pressure.

4, Jinan pipeline pump group should be installed to avoid direct sunlight and rain.

5, Weihu pipeline pump inlet should be installed vacuum pressure gauge, the export flange should be installed pressure gauge to observe and control the operation of the pump. Pressure gauge should be the actual range of 2 to 3 times the appropriate pressure.

6, Weihu pipeline pump inlet and outlet piping should be installed gate valve to facilitate maintenance and operation regulation.

7, wiring: must be required by the nameplate correct wiring, wiring, the terminal must be strong, do not allow loose, otherwise, will cause poor contact caused by phase loss burner.In order to ensure reliable operation of the motor, electrical switch should be installed overload Protection device, and according to the motor nameplate on the current requirements to adjust the size of the protection device settings.

Warning: If the overload protection device is not installed, it will cause the motor to burn out due to the sudden increase of the current when the outlet valve is fully open or when the large flow is running or under certain circumstances.

8, in the inhalation state (water level below the impeller axis or water level below the pump inlet axis), the standard atmospheric pressure, the pump installation height H = 10- (NPSH) r-0.5-hw, hw for the suction pipe resistance Loss (formula in the calculation unit: m).

9, in order to facilitate the start before the Jinan pipeline pump irrigation, can be added at both ends of the check valve by a bypass valve, before the pump starts to open the bypass valve to the pump irrigation, filled and closed, easy to use. In the high-rise building water supply or outlet pressure greater than 0.2MPa pump, in addition to the discharge port with a gate valve, but also between the pump outlet and gate valve with a check valve, so as to avoid sudden power failure caused by high pressure water impeller damage.

After reading the above description, we know how to install Jinan pipeline pump? Later Xiaobian will continue to release some of the relevant contents of the pipeline pump, welcome to the pump pump interested friends continue to our website.
