Double suction pump, double suction pump impeller, the fertile Pump (certified merchants)

 Double suction pump efficiency reasons for a decline, due to dual flush water suction pump impeller and pump impeller flow channel wall and the water became too rough double suction pump, the friction coefficient of the pump flow channel increases, plus Sheung Shui in the flow rate of the pump greatly increased head loss. Hydraulic efficiency is reduced. 2, due to prior drug dosing pump or water quality and other reasons, the pump housing severe fouling or corrosion. Severe fouling pump housing can increase the pump casing wall thickness of about 2ram, dirt and water pump wall to form tumors horizontal double suction pump, so that the pump volume reduced, reducing pumping, and runner rough, increased head loss. Customer product efficiency and hydraulic efficiency are reduced. 3, casting defects caused due process pumps, cavitation, erosion, corrosion and chemical attack and other causes produce the pump runner voids or cracks produce water flow vortices caused by energy loss. Hydraulic efficiency is reduced. 4, the surface of the impeller cavitation. Negative pressure due to the dorsal surface of the blade is running, when the pressure Pk5, volume loss and mechanical losses. Since the pump using a long time, mechanical wear and tear resulting leakage and resistance increases, the volumetric efficiency and mechanical efficiency. For these reasons, the pump performance deteriorated. Operating efficiency is reduced by 2% to 5%, severe pump efficiency can reduce more than 10%. Double suction pump no water absorption of other factors (1) end of the valve open. Pumps are usually set aside for too long double suction pump works, the bottom valve gasket is stuck dead, no bottom valve gasket may rust. (2) the bottom valve is clogged filter network; or the end of the valve caused by diving in the sludge layer filter clogging. (3) impeller wear serious. The long-term use of the impeller blades wear, affecting the pump performance. (4) a faulty valve or check valve or blockage will cause no water flow decreases. (5) The Department of Lu pipeline leak will affect the mention of water.
