Vertical centrifugal pump installation method and the schematic diagram

vertical centrifugal pump cover an area of an area small, easy installation, simple structure is the most choose centrifugal pump product design or procurement staff priority centrifugal pump products, vertical centrifugal pump purchase cost also is slightly lower than horizontal centrifugal pump, in addition to choose when the system pressure is higher or conveying high temperature hot water horizontal centrifugal pump is better, other commonly used the pressurization can use vertical centrifugal pump products. Such as commonly used type DL vertical multistage centrifugal pump, centrifugal pump CDLF type vertical multistage stainless steel pipes.

vertical centrifugal water pump installation method:

1, before installation to check the pump and motor in good idle condition. Such as pipeline not installed, can install first pumps, according to the center line of the drawing at the inlet and outlet of the water pump, piping installation. Such as pipeline has been installed, to ensure the in and out of line in the center of the same line, and near the import and export pipeline installation. In order to avoid deformation affects the performance and service life.

4, pump and motor is the overall structure, installation without alignment, so installation is very convenient.

5, when installation must tighten the anchor bolts, so as to avoid when starting the influence of vibration on the water pump performance.

6, check carefully before installation of pumps pump flow passage without affecting the operation of the pump hard objects ( Such as stones, iron grain, etc. ) In order to avoid damage to the impeller and pump body water pump run time. The vertical centrifugal pump with flange and in and out of the pipeline connection, and in the pump base mat hard objects to prevent damage to the pump body and piping, use marker to mark the pump base four empty bolt hole of the diagonal and the center position.

7, for the sake of easy maintenance, use both, in the import and export pipeline pump is the installation of a control valve and install a pressure gauge, near to the pump discharge to ensure the rated head and flow rate within the scope of operation, to ensure normal operation of pump, increase service life of the pump.

8, pump used for occasions, suction shall be fitted with bleaching, and imported line carefully too many corners, at the same time can not have leakage, leakage phenomenon.

9, installed directly pump can be placed on the basis of high - 30 40 mm ( Prepare filling slurry with) 。 And then correcting, and wear good anchor bolt, filling cement mortar, after 3 ~ 5 days after the cement dries up. Correction again, after being completely dry cement, tighten the anchor bolt nut.

10, installation line ', 逬, outlet pipe should have their own support, should not make the flange pipe under too much weight of the pump.

11, measuring well prepared the height between the base and the pump base, reasonably set aside the height of the shock absorber or cushioning.

12, remove the pump with impact electric drill hole, according to the water pump four diagonal and bolt hole center distance, embedded anchors or screw.

13, discharge line such as non-return valve should be installed outside the gate.

14 after install, changing the pump shaft, impeller should be no friction or deaths, otherwise the pump should be disassemble to reason.

15, vertical centrifugal pump installation is divided into two kinds of rigid connection and flexible connection
