Mine use wear-resisting multistage centrifugal pump slot installation diagram and matters needing attention The two pump industry in changsha

Mine with wear-resisting multistage centrifugal pump installation note:

mine with wear-resisting install valve in the import and export of multistage pump and rubber seismic section ( Pipeline compensator) For easy maintenance.

on the pump installation order, to import and export pipeline connection the self-contained bolt, tight fixed bolt again, when the connecting line in case the pump produce tensile stress, damage to the pump.

outlet line distance ( High) The job, should according to install the check valve at the exit, in case the parking with the pump produce destructive water hammer.

import and export pipeline configuration of water pump: to reduce the pipeline flow resistance, improve the efficiency of pipeline transportation, the piping should be greater than the pump of the pump import and export of a level.

import and export pipeline should set the gravity support system of pump, the pump can't inherit the piping weight.

mine with wear-resisting multistage centrifugal pump slot installation schematic diagram and note:

1, high positive pressure state

characteristics description: pump installed in the bottom of the reservoir, reservoir within the medium is in a state of positive pressure, pump inlet valve is opened, reservoir fluid can flow into the pump chamber. This state of pump, exact data must be getting to negative pressure in the reservoir, and the company contact again, before finalize the design.

4, low state of tank bottom valve not installed siphon barrel

characteristics description: pump installed in the upper portion of the reservoir, at the inlet pipes installed near the pump inlet a help start the siphon barrels, before you start the pump should be siphoned barrels filled with liquid. In this installation method of pump suction ( Refers to the pump inlet to the liquid surface height) Within 2 m. Siphon barrel can be made according to the medium of adapt to the different selection of materials and manufacturing processes, production requirement is sealed well siphon drum, can't leak leakage, siphon barrel size calculation method is as follows: V = ( 3 ~ 5) * PI d2/4 * L, d: inlet pipe diameter, L: imported tube length, V: siphon bucket volume, according to calculate the volume and the size of the existing materials, to determine the siphon barrel diameter and height.

5, low state of tank bottom valve

characteristics description: pump installed in the upper portion of the reservoir, the inlet piping to be installed at the bottom of the bottom valve, every time before you start the pump, to pump cavity filled with liquid, and should not be empty.
