PVC lay flat hose is a kind of equipment used for farmland irrigation. When it comes to irrigation, we must talk about its water supply. For PVC lay flat hose, its water supply device includes water source, PVC lay flat hose pump, flow and frequency converter, fertilizer mixing box and fertilizer injector. In order to ensure the normal delivery and dripping of irrigation water, the water entering the water belt must have a certain pressure.
The PVC lay flat hose pump uses existing water towers to calculate the relative height difference between water towers and irrigation pipes. Generally, the pressure of water supply is required to reach 0.1-0.2 MPa, which is equivalent to the requirement that the relative height difference between water towers and irrigation areas reach more than 10 meters. Simple water storage tanks, such as iron barrels, water tanks, plastic tanks, cement pools and so on, should also be installed beside the greenhouse, with a general capacity of 0.5 cubic meters. The height of the tank should be about 1.5 meters from the ground. When used, water is continuously injected into the tank with miniature PVC lay flat hose pump.
Or set pressure tank beside the well. The capacity of pressure tank is 2-8 cubic meters. After pumping the well water, it is pressurized to 0.2-0.5 MPa. The pressure tank should be equipped with automatic water replenishing device to ensure uninterrupted and uniform water supply.
