1. self-priming electric diaphragm pump is a new type of agricultural water pump designed and used in recent years in China. 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, the next time it moves, no more irrigation is needed. Therefore, it is very convenient to use. The SS self suction electric diaphragm pump developed in recent years in our province is 2, 3, 4 inches, suitable for irrigation in orchard and farmland. In addition, in order to develop spray irrigation technology, China has jointly designed and produced a series of BPZ type six kinds of self - suction sprinkler pump series. This type of pump is not only used in agriculture, but also widely used in construction sites.
2., storing water by water storage method uses a large wooden bucket or water tank to store water, put it near the pump, and make the bottom of the bucket slightly higher than the outlet of the pump, or when the pool is built near the side of the pump house, it will slightly lower the pool bottom and form a storage tank. The water pipe is used to connect the bucket (or the pool) to the water hole of the pump body. Before stopping, fill the bucket with the water out of the water pipe and fill the bucket with water at the next start. This method is filled with water, and it is easy to use.
3., the exhaust muffler of a small engine is discharged by installing the engine exhaust and vacuum pumping method, and a specially designed exhaust water diversion device is installed. The exhaust air from the engine is drained away by the exhaust gas during the working process, so that the vacuum degree of the pump is generated. During operation, start the engine first, then compress the handle of the waste water diversion device downwards, close the exhaust gas outlet, and exhaust gas from the engine is discharged through the exhaust nozzle. Because the exhaust gas jet speed is large and the pressure is low, it will cause suction. The water pump begins to absorb water when a continuous gas - water mixture is seen. Then the water filling and exhaust holes on the pump body are closed, then the handle is brought up, the exhaust gas outlet is opened, and the pump is transferred to the normal work. This water filling method is only suitable for small caliber pumps powered by small gasoline or diesel engines.
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.
