[Installation and Precautions] 1, the installation of the pump is reasonable, the normal operation of the pump and the life has a very important impact, so the installation and calibration must be carefully. 2, according to the installation of the size of the anchor bolts, do a good job of concrete foundation. 3, after the foundation cement is solidified, based on the installation of the pump, check the level of the water pump and the motor shaft with the spirit level. If not, adjust the horn to the level and tighten the foot nut after adjustment. 4, check whether the rotating parts of the pump stuck rub phenomenon should be strictly checked pump shaft and motor concentricity can be adjusted to make it concentric sheet, and finally turn the coupling by hand, turning the phenomenon even without rubbing evenly Normal. 5, the pump suction and discharge pipe should have their own bracket, does not allow the weight of the pipe directly to withstand the pump, so as to avoid the pump crushed. 6. When the pump is installed above the liquid level (within the allowable suction range of the pump), install the upper bottom valve at the end of the suction pipe and set the irrigation screw hole or valve on the discharge pipe for pump start Before filling the pump; pump installation position below the liquid level, the suction pipe should be installed on the control valve and filter device to prevent debris sucked into the pump, the filter area should be greater than 3-4 times the pipe area. 7, lift the pump in the outlet flow control valve on the outer pipe should also be installed check valve to prevent water hammer damage suddenly shut down. 8, must ensure that the pump installation height in line with the pump cavitation margin, and consider the pipeline loss and medium temperature. ã€Pump start, run and stop】 1, pump should be filled before filling pump plus enough liquid, non-liquid start. 2, close the outlet valve, turn on the power immediately after checking the pump steering steering pump must be the same, is strictly prohibited reverse operation. 3, the pump reaches the normal speed after starting, and then gradually open the outlet valve, and adjust to the required conditions into operation. In the discharge valve on the pipeline closed, the pump can not work continuously for more than 3 minutes. 4, shut down the valve should be the first exit, and then cut off the power. [Maintenance and care] 1, regular inspection of pumps and motors, replacement of vulnerable parts. 2, often pay attention to the bearing box filled with calcium-based grease, to ensure a good bearing lubrication. 3, long-term shutdown does not use inch, in addition to the pump of corrosive liquid into the net, but should pay attention to the various parts and pump flow channel clean, and cut off the power. 4, the pump is strictly no-load operation. 5, medium containing solid particles, should be added at the pump inlet filter.
