Greenhouse film equipment is very common in current agricultural production. Shandong Hengxiang Plastic Machinery Co., Ltd. is also one of the main manufacturers of greenhouse film equipment. The following editor will introduce the use of greenhouse film equipment:

1. Layout spacing The range of micro-pore water flow is between 1 stone and 3 pairs of meters. In order to achieve a higher irrigation uniformity, the spacing of micro-spraying belts should be 3 pairs of meters, that is, generally one belt is laid per furrow.

2. Matching quantity The number of micro-spraying belts is determined by the water output of a single well. The water output of a single well is 40 cubic meters/hour, and 3 groups of 6-8 belts are required for each group (10 meters). The water output of a single well is 25 cubic meters/hour, and 3 groups of micro-spraying belts are also required, with 4-5 belts in each group, so that they can be used alternately.

3. Water distribution device Since the flow rate of the low-pressure pipeline outlet is large, a water distribution "little white dragon" with a diameter of 11 mm needs to be connected after the water tap. A water distribution outlet is set every 3 pairs of meters. The water distribution outlet is made of a water distribution reducer tee with a diameter of 110x40 mm. The tee outlet is connected to the micro-sprinkler belt with a quick connector. The micro-sprinkler belt can be used in groups or in a single pipe.

4. Pressure regulating device The current low-pressure pipeline outlet generally has a water head of only 0.2-0.5 meters, which cannot meet the normal operation of the micro-sprinkler belt. The existing water pump and pressure regulating pipe need to be adjusted and modified. The pump head selection needs to meet the working water head condition of 6 meters at the far outlet of the low-pressure pipeline (considering the loss of the micro-sprinkler belt along the way). The pressure regulating pipe of the low-pressure pipeline plus micro-sprinkler irrigation system is suitable for installation at the water tap far away from the well, so that the pressure regulating pipe does not need to be moved frequently. The height of the pressure regulating pipe of this system generally needs to be 6 pairs of meters, and it is connected to the tee on the water tap with a hose.
