Controlled self-priming water pump body is a reference motor is mounted. Because the general pump weight than the motor, and it and other equipment with pipelines interconnection, when other equipment is installed, self-priming clear water pump body position is also determined, and the motor position can be controlled according to self Suck the position of the pump body to make the appropriate adjustments.
　　
Self-priming clean water pump body installation steps are as follows
　　
1. Self-absorption self-priming clear water lifting the body
　　
For small pumps, it can lift up to 4 feet on the base. For medium pumps, use the hanger and roller bar to roll over the bevel for transport and installation. For large and medium-sized pump, can use the H-shaped wooden crane hoisting, sometimes with single wooden pallets and other pulley group together to hoisting. In addition, the plant can be used or based on the original
　　
Some hoisting machinery (such as bridge cranes, electric hoist, etc.) will be hoisted directly to the pump. When hoisting, the slings should be bundled in the lower part of self-priming clear water pump body, not tied to the shaft or bearing.
　　
Self-priming clear water pump body measurement and adjustment
　　
Measurement and adjustment of the pump body include finding, looking for elevation and leveling three aspects.
　　
(1) to find is to find self-control self-priming water pump body vertical and horizontal centerline. Self-priming self-priming water pump body longitudinal centerline is based on the pump shaft centerline; transverse centerline outlet pipe centerline shall prevail. When looking for timing, it is necessary to measure and adjust according to the installed equipment center line (or the centerline of the foundation and the wall column) so that the vertical and horizontal center lines of the self-priming clear water pump body meet the requirements of the drawings, and Other devices are well connected. Self-priming self-priming water pump body vertical and horizontal centerline according to the size of the drawings allow deviation of ± 5mm range.
　　
(2) Find the elevation of the pump is based on the centerline of the pump shaft. To find the elevation generally use the level to be measured. Measurement, the benchmark on the benchmark set on the factory premises, measuring the level of the mirror heart, and then the benchmark will be moved to the journal, measuring the distance from the axial plane to the center of the mirror, and then can be calculated according to the formula pump The elevation of the axis centerline.
　　
Height of pump shaft center = (height of mirror center, distance between shaft and mirror center) Diameter of pump shaft / 2
　　
Elevation adjustment, but also with the increase or decrease self-priming water pump body feet and the seat between the pads to complete. Deviation of pump shaft center height ± 10mm.
　　
(3) leveling self-priming water pump body centerline position and elevation to find good, they began to adjust the level of self-priming water pump body, first with fine? 0.05mm / m square level instrument, self-priming clear water pump Body before and after the journal at both ends of the measurement. Adjust the level, the pump can be controlled self-priming body feet and the base to add thinning to adjust the iron. Self-control self-priming water pump body horizontal tolerance is generally 0.3-0.5mm / m.
　　
Self-control self-priming clean water pump body centerline position, elevation and level of degree to find a good, you can self-priming self-priming clean water pump body and the base of the connecting bolt tighten, and then use the level of instrument inspection?绻 绻 挥 斜 ??
　　
Motor installation
　　
The main task of installing the motor is to adjust the centerline of the motor shaft to the centerline of the shaft of the centrifugal pump in a straight line. Multi-stage bedroom centrifugal pump and the motor shaft is connected together with a variety of couplings, so the motor is mainly the installation of the coupling to find out the specific method of alignment will be introduced in the assembly of the coupling .
　　
There must be an axial clearance between the coupling halves of the motor. Its function is to prevent the shaft of the horizontal multistage centrifugal pump from reaching the shaft of the motor or the shaft of the motor shaft. Therefore, this gap must have a certain size, generally larger than the sum of the amount of movement of the centrifugal pump shaft and the motor shaft. Usually the drawings on this gap have provisions, such as the drawings do not have this regulation, you can refer to the following figures to adjust: small centrifugal pump is 2-4mm; medium centrifugal pump is 4-5mm; large centrifugal pump is 4-8mm.
　　
Secondary grouting
　　
After the motor is fully installed, the secondary grouting can be carried out. After the second grouting cement mortar hardened, the center of the coupling must be re-calibrated to see if there is any change and record.
