Sprinkler pumps are mainly used for sprinklers, landscaping sprinklers, fire sprinklers and other sanitation vehicles.
Sprinkler pumps are available in a variety of sizes and are now described in detail:
Model: 80QZB(F) 60/90 Flow (m3/h): 60 Flow rate for one hour 60m3: 90 is lift (m): 1180 Shaft power (kw): 22.5 Self-priming height (m): 6.5 Self-priming time (min/5m): 1.0 Efficiency: 65% Remarks: Left and right rotation models: 65QZB (F) 40/45 Flow rate (m3/h): 40 is 1 hour flow rate (m3): 45 is lift (m): 1450 Shaft power (kw): 9.25 Self-priming height (m): 6.5 Self-priming time (min/5m): 1.0 Efficiency: 65%
This series of pumps uses external mixing self-priming structure, the pump should have the right amount of liquid. After the pump is started, the impeller rotates and a negative pressure is formed at the inlet of the impeller. The gas in the suction pipeline is mixed with the liquid in the pump and passes through the pressure chamber to enter the gas-liquid separation chamber. Because of the difference in the specific gravity of the gas and liquid, the gas is separated from the liquid and discharged from the outlet pipe. The liquid sinks in the gas-liquid separation chamber and is circulated repeatedly until the gas in the suction pipe is drained and filled with liquid to complete the self-priming process. The pump started normal infusion. Therefore, in order to ensure that the pump has good self-priming performance, the following conditions must be met:
1. Before the pump works, the pump's liquid inventory must be higher than the pump shaft. Therefore, the pump inlet must be connected with an upwardly bent elbow and then a horizontal pipe and quick connector. The quick connector center line must be higher than the pump shaft centerline 300. Mm.
2, the import pipeline system must ensure that no air leakage.
3, suction pipe suction head must be submerged in water, so as not to inhale the water pipe.
4. When connecting the outlet pipe to the pump outlet, it must be ensured that the length of the straight pipe is ≥200 mm and then the bend pipe.
What should I do if the water pressure of the sprinkler is small? First of all, the most likely problem is that the sprinkler filter is blocked because the water loaded into the sprinkler cannot be completely clean tap water. It may be dirty pool or water pumped in the pond. Netease was blocked by debris, such as sand, plastic bags. Just remove the filter element from the filter and clean it to restore normal operation. The position of the filter is near the sprinkler pump.
Another possibility is that the pressure of the sprinkler pump is insufficient, resulting in the sprinkler pump not pumping water. The insufficient pressure of the sprinkler pump is usually caused by two reasons: one is that the impeller flow path or the suction pipeline is blocked, or the wear of the impeller is already broken. . Second, the power is too low speed.
If the impeller is damaged, then it is necessary to change the water pump, and the power is not enough. Just increase the throttle.
