LG, LG-B type high-rise building water supply multistage pump Installation instructions: 1, the installation should be checked in the presence or absence of impurities in the pump flow passage. 2, LG, LG-B vertical multistage pump mounting location should be as near water. 3, LG, LG-B-type vertical multistage pumps with base mounting There are two ways 40LG12-15X5 multistage pumps, a direct mounted on a cement foundation rigid connection, and the other is the use of JGD type Damper flexible connection, the specific method installation illustration. 4, will be directly installed on the booster pump on the basis of 30 to 40 mm (ready filling grout purposes), and then corrected, and put bolt, filling cement mortar, after 3 to 5 open cement dry, recalibration, until the cement is completely dry, tighten the bolt nuts. 5. When the installation of the pipes, into the outlet road should have their support, not to make LG, LG-B vertical multistage pump flanges to put too much weight line. 6, LG, LG-B-type vertical multistage pumps have suction lift for the occasion, the inlet side should be fitted with a foot valve 40LG12-15X3 multistage pumps, and import pipeline should not have too many corners. And shall not have water leakage phenomenon 7, the inlet piping preferably mounted filters to prevent contaminants from entering the interior of the impeller. There are cross filter inlet area should be an area of ??3 to 4 times, in order to ensure the free flow of liquid. 8, in order to maintain security and ease of use, the pump inlet piping and installation of a valve installed near the outlet of the pump and a pressure gauge, and install a self-position valve (water hammer) in front of the pressure gauge to ensure that the pump within the nominal range operation, to ensure the normal operation and service life of the pump. 9. For imports expanding access, please use the eccentric reducer pipe joints. Product Overview GDL type multi-stage pipeline centrifugal pump is my unit with the user on the basis of domestic and foreign outstanding pump on fire-related requirements and standards, and design and manufacture a new generation of products based on JB / TQ6435-92 standards. Vertical segmental external stainless steel shell structure, making inlet and outlet located on the same level and the same caliber as the valve can be installed in the pipeline, it also focused on the high-pressure multi-stage pump, the vertical pumps of easy installation advantages of small footprint and pipeline pump. Multi-stage pump with high efficiency, smooth running, etc., and seal with wear-resistant mechanical seal, no leakage and long service life. Features with high efficiency, stable operation and other advantages, and seal with wear-resistant mechanical seal, temperature ≤100 ℃ 40LG12-15X6 multi-stage pump, working pressure ≤1.6MPa (16kg / cm3). Traffic: 5-300m3 / h Head: 5-250m speed 2900r / min Product use GDL type pump for liquid transport water or physical and chemical properties of the high-pressure operation of the system, such as high-rise building water supply, boiler feed water, fire protection systems, such as transportation or pipeline pressurized purposes. GDLF type pump with integral stainless steel (ZG1Cr18Ni9Ti) material, suitable for chemical, food, brewing, pharmaceutical, textile and other industries. It can be customized according to user requirements 304 or 316L stainless steel.
