- Water Pump

Gasoline pump is a centrifugal pump. Working principle of centrifugal pump is filled with water in the pump case, the motor drives the impeller rotation, resulting in a centrifugal force, the water in the impeller, under the action of centrifugal force to jilt to peripheral flow into the pump shell, so the impeller center reduced pressure, the pressure is lower than the water tube, under the action of water on the pressure difference by suction tank into the impeller. So the pump can continue to absorb water and continue to supply water. Main applications: agricultural drainage and irrigation, industrial drainage and other equipment.

    3. Smooth operation, reliable and convenient assembly and disassembly, etc.
    4. The ordinary petrol water pump makes a little more noise.

    Gasoline pump maintenance

    1. Change the oil: For the first use, change the oil after the first month or after 20 hours of use, and then every six months or after 300 hours.
    2. Air filter oil maintenance:Clean the filter element with non-combustible or high-ignition point solution and dry it thoroughly; Then dip the filter element into the clean oil, squeeze out the excess oil, and reinstall.
    3. Spark plug maintenance:Visually check the spark plug for obvious wear or breach of the insulation ring. If there is a problem, replace the spark plug with a new one. Measure the spark plug gap with the plug gauge, the gap is 0.70-0.80mm. If not, the electrode should be adjusted to correct the gap and remove the carbon deposit.
    4. Storage:If the gasoline pump is not used for a long time, close the oil inlet valve of the carburetor first and let the pump of the gasoline engine shut off automatically when it is stopped for the last time (if it is not used for a long time, the gasoline stored in the carburetor will damage the carburetor). Clean the impeller chamber with clean water from the inlet pipe until the sediment is removed. Finally, the remaining fuel oil in the tank is released into a special container for proper preservation. The machine is stored in a cool, ventilated and dry place.
