Pump industry suppliers - Corrosion resistant mortar pump cavitation problem solution

the corrosion resistant mortar pump cavitation problem solution

is corrosion resistant mortar pump power plant desulphurization, waste water recycling system in common pump, caused in the application of corrosion resistant mortar pump cavitation is how to return a responsibility, how to deal with? Find the circulating water pump cavitation first reason and common fault?

corrosion resistant mortar pump common fault condition

1, the operation is not in two months, was destroyed by the cavitation impeller leaves; in full open valve cases operation

2 entrances and exits, pump pressure 0. 7 - 0. Whose hands often shake, 8 KGF/cm2, significant explosion.

3, condenser and circulating cooling circulating water system the difference in temperature of 25 ℃, everything is normal temperature difference should be 8 ~ 11 ℃

because the current pump pump head too high, not in excess of the prescribed according to the laser cutting impeller, it is important to design the new impeller, because the pump head lower, in addition to maintaining the total flow of the pump, centrifugal pump in order to ensure that the provisions of the specific speed than is sure to speed by 960 r/min to 740 r/min. Upgrading the actual effect of pump cavitation condition has not appeared, impeller for two years or so, could reduce the maintenance of labor and maintenance costs; Water flow can consider capacity, condenser vacuum value, than index, improve the load rate of the diesel generator.

corrosion resistant mortar pump status parsing

1, circulatory cooling circulating water temperature 25 ℃, everything is normal temperature difference should be 8 ~ 11 ℃, shows that the total capacity of cooling circulating water circulation system is not enough.

2, there was a significant explosions, shows that the water pump cavitation condition is more serious.

3, pump head is 32 meters, obviously because of excessive water pump motor type pump head, focus on low pump pump head, big traffic, cavitation performance is poor under the load of work, leaf damage and the serious cavitation.

upgrading corrosion resistant mortar water pump plan

according to the situation of analytical and experiment on the spot, and master all material investigation, people related to the customer put forward a resolution proposal of leading cadres and professional and technical personnel, and clearly put forward the renovation plan.

1, the capacity of 110 m3 / h, condensing water cycle system is 3850-6050 m3 / h, single pump total flow of 3025 ~ 3850 m3 / h.

2, pump leaking pipe tube for Dg1000, length of L2 = 25 m, a bottom valve pump, four 900 bend.
