The method of realizing self-absorption of water pump
1. Install the bottom valve. Generally, the way to realize the self-priming of the pump is to install the bottom valve. The bottom valve is installed in the water inlet position, so that only the first need to fill the water outside, no need to fill the water again in the future.
2. Water storage method Fill water with a large wooden barrel or water cylinder to store water and place it at the outlet of the centrifugal pump; Or when a pool is built near the side of the centrifugal pump pump house, the bottom of the pool is slightly lowered to form a storage pool. Connect the bucket (or pool) to the pump body filling hole with a water pipe. Before shutdown, use the water from the outlet pipe to fill the barrel for reserve, and the next time to start the centrifugal pump, it can be filled with water. This method fills with water and is easy to use.
3. A cylindrical water tank is installed in front of the pump. The top of the tank is a hemispherical projection. An upper suction pipe is arranged in the middle of the cabinet. Before the first use of the water tank, fill the water tank with water from the water filling port, and then close the water filling port. Start the centrifugal pump operation, the instant pump will pump the water in the water tank, the water level gradually decreases, the volume gradually increases, forming a vacuum state, producing suction, so as to suck the water of the suction pool into the water tank, the pump continues to run, the water is continuously pumped out.
