QDL.QDLF stainless steel multistage centrifugal pump installation and use

【Installation and Precautions】 1, pump installation is reasonable, there is an extremely important impact on the normal operation of the pump and service life, so the installation and calibration must be carried out carefully. 2, according to the installation of the size of the anchor bolts, do a good job of concrete foundation. 3, to be based on the solidification of the cement, the pump installed on the basis of the application of the level of inspection? Counseling coal stolen? Cape is the angle? R, if not level, use the horn adjusted until the level, . 4, check whether the rotating parts of the pump stuck touch 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 the pump to start Before filling the pump; pump installation position below the liquid level, should be in the intake pipe safety valve and filtration control device to prevent debris sucked into the pump, the filter area should be greater than the pipe area 3-4 times. 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. 【Pump start, run and stop】 1, pump should be filled before filling pump plus enough liquid, non-liquid start. 2, the closure of the outlet valve, immediately after the power supply check sucking 淖 虮 虮 匦 tritium building rose 淖? 蚣? Fen Hulun Long ⒀ jurisdiction Chang Jiao folk br br /> 3, after the pump reaches the normal speed, Then gradually open the outlet valve, and adjust to the required work? R put into operation. In the discharge valve on the pipeline closed? R, the pump can not work more than 3 minutes. 4, shut down the valve should be the first exit, and then cut off the power. 【Maintenance and repair】 1, regular inspection sucking coal stolen gray attitude 鹆 carelessly br /> 2, often pay attention to the bearing box filled with high-quality calcium-based grease to ensure a good bearing lubrication. 3, the long-term shutdown does not use the track? Mei criticized the onion smashed Wo Chen cracked 猓 ?? ⒁ 飧 飧 Tartar test? Ammonia 媚 诹 鞯 Lai that hammer 删 bluff? ⑶ release light brilliance? Br /> 4, No-load pump is strictly prohibited. 5, medium containing solid particles, should be added at the pump inlet filter.
