What is the working principle of PVC lay flat hose? The principle is to bring water pressure through PVC lay flat hose and micro-nozzle to the field, through the outlet hole of PVC lay flat hose, under the action of gravity and air resistance, to form a drizzle-like spraying effect. So it is very important to provide water pressure for it. How to provide water pressure for PVC lay flat hose? We have three ways.
Using existing water towers, it is necessary 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 relative height difference between water towers and irrigation areas up to 10 meters.
Pressure tank is installed beside the machine well. The capacity of the pressure tank is 2-8 cubic meters. After pumping water into the machine well, the pressure tank is pressurized to 0.2-0.5 MPa. The pressure tank should be equipped with automatic water supply device to ensure uninterrupted and uniform water supply.
Simple water storage tanks, such as iron barrels, water tanks, plastic tanks, cement pools, etc., are 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.
The above three methods can provide water pressure, and see which method your conditions can implement.
