1 self suction pipeline centrifugal pump is a new type of pump which is designed and manufactured in our country in recent years. It is 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.
A large barrel or tank water storage reservoir with 2 water filled with water and placed it near the water pump, and the outlet end slightly higher than the pump barrel; or in the side near the pumping station built out of the pool, the pool will be slightly lower bottom to form 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.
3 using engine exhaust vacuum filling method to remove small engine muffler, exhaust diversion device installed on the special exhaust using the engine working process, pumping out the air in the pump, the pump produces a certain degree of vacuum. When to start the engine, and then the waste water diversion device hand pressed down to close the exhaust outlet, from the exhaust gas discharged by the engine, through the exhaust gas jet nozzle, the exhaust jet velocity, low pressure, and thus 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.
4 pump before the water tank water pump before the installation method in a cylindrical tank, the top of the cabinet in the cabinet for the hemispherical protrusions, a suction device on the central pipe, the pipe is lower than the height of the barrel body, the lower part of the cabinet body outlet and connected to a water pump suction pipe. Tanks for the first time before use, from the water inlet of the water tank full of water, and then fully closed outlet. Start water pump, pump the water in the tank will be instantly removed, the water level decreased, the volume increases, the formation of a vacuum to produce suction to the suction tank of water into the tank, the pump continues to run, the water is pumped out Everfount
