1. Self-priming centrifugal pump This pump is our country in recent years, design, manufacture, promote the use of a new type of agricultural pumps. It does not end the valve, before starting, pouring a small amount of water into the pump, start, you can automatically vacuum water. After shutdown, the next restart, you do not need to be irrigated. So easy to use. In recent years, our province developed SS-type self-priming centrifugal pumps, specifications 2,3,4-inch, suitable for orchard, farmland irrigation purposes. In addition, in order to develop sprinkler irrigation technology, China has jointly designed and produced BPZ six types of self-priming sprinkler pump products. This type of pump not only used in agriculture, but also widely used in construction sites. 2. Water storage method Fill water with a large barrel or water tank, put it near the pump, and the bottom of the barrel slightly above the water outlet; or near the pump house to build a pool, Slightly lower the bottom of the pool to form a reservoir. Connect the bucket (or tank) to the pump body watering hole with a hose. Downtime, the use of water out of the water bucket filled with spare, the next start, they can self-flowing water. This method of filling water, easy to use 3 using the exhaust pump vacuum exhaust method to remove the muffler of a small engine, fitted with a special exhaust gas intake device, the use of exhaust emissions during engine work, pumping the air pump , So that the pump produces a certain degree of vacuum. In operation, the engine is started first, then the handle of the exhaust water inflow device is pressed downward to close the exhaust outlet, the exhaust gas discharged from the engine is discharged through the exhaust nozzle, and as the exhaust gas jet speed is high and the pressure is low, . When you see a continuous flow of gas and water bubbles appear, the pump began to absorb water. Then close the pump body water-filled vent, then lift the handle, open the exhaust outlet, the pump is transferred to normal work. This method of filling water, only for small gasoline or diesel engine powered small-bore water pump. 4. The water tank before the pump water diversion method in front of the pump to install a cylindrical tank, the top of the hemispherical dome projection, the central section of the device suction tube, the nozzle is lower than the height of the barrel body outlet and the lower part of the pump Suction hose connection. Before using the water tank for the first time, fill the water tank with water from the water inlet and then close the water inlet. Start the pump running, the water pump will instantly pump the water tank away, the water level gradually decreased, the volume gradually increased to form a vacuum state, resulting in suction, which sucked the water sucked to the tank, the pump continues to run, water on A steady stream of pumping out.
