The pump is a common equipment in the daily life of the farmhouse. Then you know the factors that reduce the efficiency of the generator pump. Here are five simple factors that may cause the pump to decrease in efficiency.
1. Due to the erosion of the water flow, the inner wall of the pump flow passage and the impeller surface become rough and uneven, the friction coefficient of the flow passage in the water pump increases, and the flow rate of the water in the pump is large, and the head loss increases. The hydraulic efficiency is reduced.
2. Due to the application of drugs or water quality before the pump, the pump casing is seriously fouled or corroded. Severe fouling in the pump casing can increase the wall thickness of the pump casing by about 2 ram, and the scale of the pump wall is scaled, which reduces the volume of the pump body, reduces the amount of pumping, and the flow path is rough, and the head loss increases. Both customer productivity and hydraulic efficiency are reduced.
3. Due to casting defects, cavitation, abrasion, corrosion and chemical attack caused by the pump processing process, voids or cracks are generated in the pump flow path, and vortices are generated when the water flows, resulting in energy loss. The hydraulic efficiency is reduced.
4. Cavitation on the surface of the impeller. Due to the negative pressure generated when the blade is running on the water surface, when the pressure Pk
5. Volume loss and mechanical loss. Due to the long pump life, mechanical wear causes leakage and increased resistance, resulting in reduced volumetric efficiency and mechanical efficiency.
The above reasons make the performance of the pump worse. The operating efficiency is reduced by 2 to 5%, which can seriously reduce the pump efficiency by more than 10%.
The Electronic Repeller is one of the most recent developments in pest repellents.These electronic repeller work by causing ultrasonic waves through the air. The aim is that this electromagnetic technology drives mice, moles, mosquitoes hurrying from the realm, makes an invisible barrier for the pest and never to be seen anymore.
Our electronic repller is certificated by CE, ROHS, may be sales on European and American markets.
These electronic repeller is primarily featured by safety, no chemical, odorless, no harm to pets and other no-target animals. Compared to other competitors, this device is more clean and tidy, and could be used year and year.
