In order to use your pump and the best way to ensure long operating life , you need to pay attention to the following points when using the pump. At the same time you also need to know some common damage to himself can deal with problems encountered when pump failure .
 
Note the use of pumps:
 
- To have a strong and continuous water and prolonged use of the pump , you should note the following points : Strong to water , to pump water pipe commonly used types of 34 mm , and output lines diameter 27 mm .
 
- For deep well centrifugal pumps , you must priming before use and add a one-way valve in the discharge tubes . Without water , the machine will howl , leading to damage the seal and pull the fire engine pump .
 
- Be fitted with mesh water filter to filter input in the soil can lead to jamming the impeller .
 
- When the pump from the tap water is very weak and need priming before fitting boots and more like one-way valve pump deep wells . Without water , the seal will be damaged by the heat and water back into the machine causing burning machine .
 
- Be fitted with a water tank of 400 liters or more ( depending on demand ) set on high to stabilize water pressure in the house and rooms of the cup .
 
The Common damage :
 
- Failure of the most common is the water pump . This incident was caused by a leak in the pipe , down a one-way valve , float down automatically ( in the tank ) , broken seal , rotor and bearing down ( if not immediately fix the engine will fire pumps ) .
 
- The engine pumps not operating due to insufficient voltage ( less than 160V , you should add a separate voltage regulator for water pump if needed ) . If the condition lasts weak power , the machine will lead to howling , and as a result it from burning machine .
 
= > How to fix it : When you hear howling pump power cut immediately . When you use the pump assembling a circuit breaker or CB for water pump house.
 
- Missed pump relay in pressure in the pipes due to the non- return valve fitted .
 
 - When the engine is turning very slow water pump and water flow are weak , so long as the two top bearings and oil pump dry . This case led to explosive or fuse immediately .
 
= > The Fix : You can small little lubricant on shaft before replacing the pump fuse new and active again .
 
- Electric motors leak Causes of this phenomenon is the seat wiring , winding engine was hit by damaged insulation shell . Also due to the motor winding is wet or has water running into the same expression .
 
= > How to fix : need dried or repair wiring .
