1. Water storage water filling:
With a large barrel or water storage tank of water, the which is placed in the vicinity of the water pump, and the water outlet end slightly higher than the pump barrel; or is in close to the pump side of the construction of the pool, the bottom of the pool decreased slightly, the formation of a storage pool. Water barrels (or pool) and the pump connected filled hole. Stop before using the outlet pipe of water flowing into buckets filled with spare, starting next time, gravity can be filled with water. This method is full of water, and is easy to use.
2. Selective self priming pump:
Not the end of valve, before starting to pump the water poured into a small, start, can automatic vacuum water. After the shutdown, then start the next time, you do not need to carry out irrigation. Therefore, it is very convenient to use. Suitable for irrigation of orchard and farmland.
3. Pump before the water tank water diversion method:
In the pump before the installation of a cylindrical tank, tank top for the hemispherical protrusions, the central device in the cabinet a suction pipe and the nozzle below and the height of the barrel body, cabinet body bottom outlet and pump suction pipe connection. Tanks for the first time before use, from the water inlet of the water tank full of water, and then fully closed outlet. Start the pump, instant water pump in the tank water is pumped out, water level gradually decreased, the volume increases, forming vacuum, suction, to suck suck the pools of water to the tank, the pump continues to run, the water continuously being pumped out.
4. Using engine exhaust vacuum filling method:
Remove the muffler of the small engine, fitted with a special exhaust gas water diversion device, the use of the engine exhaust emissions from the work process, pumping the air in the pump, the pump will produce a certain degree of vacuum. Operation, before starting the engine, and then the exhaust diversion device of hand pressed down and close the exhaust outlet, exhausted from the engine exhaust gas, through the exhaust gas jet nozzle discharge, because of the exhaust jet velocity, low pressure, resulting in the role of aspiration. When there are continuous gas water mixing bubbles appear, the pump will start to absorb water. Then close the pump body on the water filled exhaust holes, then lift the handle, open the exhaust outlet, the pump is transferred to the normal work. This water filling method is only suitable for small gasoline or diesel engine as the power of small diameter water pump.
