First, the repair of the sprinkler pump

　　 1 , the pump shell rupture can be repaired, or bonded with epoxy resin, bearing seat hole wear too much, can be used to repair the casing method, pump shell water inlet end if there are pits, grooves or uneven, available lathe turning repair.

　　 2 , pump shaft corrosion. You can use the tin to fill the spots, recesses, and then round. The pump shaft wear can be chrome plated and the bearing rotation should be flexible and noiseless.

　　 3 , water seal wear, rubber seal aging, deformation or damage, weakened water seal spring force or corrosion should be replaced.

Second, sprinkler pump repair and test:

　　 1. Assemble the sprinkler truck's water pump shaft and impeller, so that the end face of the impeller hole should be 0.10-0.50mm higher than the end of the pump shaft (refer to the impeller pump fixed by the impeller) for compaction. Refit the gasket, tighten the fixing bolt, install the water seal assembly, and lock it with a pin.

　　 2. Put the pump impeller into the pump housing, put the rear bearing lock ring on one end of the shaft, and then install the rear bearing, spacer and front bearing into the pump housing in turn (some pump bearings are integral type, then Install the integral bearing into the pump housing), review its fit, and insert the lock ring.

　　 3. Mount the V- belt hub at the front end of the pump shaft , fasten it with bolts, install the V- belt pulley and fan blade, and fasten it with a nut, but lock it with the open lock (or locking piece).

　　 4 , install the pump cover and liner (some pumps do not cover). The clearance between the impeller and the cover (without the cover requires a clearance of 0.17-0.75 mm between the impeller and the front wall of the cylinder) .

　　 5, the water pump pulley V installed in the tank measured runout should not exceed 1.0mm, typically thumb is: a pin that is suitable gap feeling when pulled impeller.

　　 6. The pump should be tested before loading. Experience is as follows: Turn the V- belt by hand , there should be no jamming phenomenon, block the inlet of the pump casing, and then add water to the impeller working chamber, turn the pump shaft, and the inspection hole should be leaked without water. If there is jamming and water leakage, the cause should be identified and eliminated.
