Multi-stage pump in the first month of work multistage centrifugal pump, oil change after 100 hours, after every 500 hours, change the oil once. ⑿, multistage pump regularly adjust the packing gland, packing indoor drip ensure normal (with a drip out appropriate). ⒀, regularly check the wear multi-stage pump shaft sleeve, wear should be replaced after larger. ⒁, multistage pump during the winter season, parking, the need to unscrew the lower drain plug pump will put the net media. Prevent cracking. After ⒂, start the motor, when the normal operation of multi-stage pump, open the export and import of vacuum gauges depending on the exhibit appropriate pressure, and gradually open the valve, and check the motor load conditions. One made of cast iron, together form the pump chamber. 3. The impeller is made of high quality cast iron, there are blades, liquid axial unilateral entry, due to unequal pressure around the impeller, there must be an axial force, the axial force to bear by the balance disc, impeller manufactured by static balance test. The shaft is made of high quality carbon steel, middle mounted impeller, with the key, the sleeve and the sleeve nut on the shaft. One end of the shaft is mounted coupling part, connected directly to the motor. 5. Seal bad made of cast iron, high-pressure water pumps to prevent water leakage back part, are fixed in the middle of the air entering the inlet section and a lot of liquid leakage, vertical multistage centrifugal pump is sealed by a water segment and end cap packing room, packing gland, packing ring and packing etc. 80D12X8 multistage pumps, filling the role of a small amount from the water seal chamber pressure water inflows. Tightness of filler must be appropriate, not too tight, not too loose also, to be able to drop by drop liquid oozing prevail. If the packing too tight, easy to heat 80D30X4 sleeve multistage centrifugal pump, while consuming power. Packing too loose, fluid loss due to lower pump efficiency. Three, D single suction multistage centrifugal pump to start moving forward and stop loading: (a) connection with the order: (1) the seal ring were tightly packed in the water segment and guide vanes bezel. (2) to guide the wing suit 80D30X3 multistage pumps in the middle, and then the guide baffle mounted wing up the middle at all. (3) will be installed and the suspect yu A shaft sleeve through the water segment, and push the impeller, spread a layer of paper in the middle of the mat, and put on the middle, pushed into the second impeller, repeat the above step, all the (3) with a spirit level to check the levelness of the base, pull tight to the foot after leveling nut filled with water base mud. (4) 3 to 4 days after the cement to dry, and then check the level of degree.
