The sprinkler is a type of sprinkler that integrates power plants, pumps, pipelines, sprinklers, and mobile devices into a single integrated sprinkler system. It sprays pressurized water at low altitude and sprays uniformly as raindrops. To the crop and the ground surface. Commonly used sprinklers include small sprinklers, large sprinkler, translating sprinkler, mobile sprinkler, reel sprinkler, pointer sprinkler, center pivot sprinkler, round sprinkler, double cantilever sprinkler And other types. Sprinkler irrigation is used for many purposes and is mainly used in crops, forestry nurseries, pastoral pastures, vegetable fruit trees, economic crops, garden turfs and flowers. In addition, it is also used for environmental control (such as dust-proof, windproof, dry-heat-proof, anti-frost, etc.), sewage treatment, aeration of fish ponds, and comprehensive spraying of liquid fertilizer, herbicide, chemical agent, pesticide, insecticide, etc. . Sprinkler irrigation is very adaptable and can be applied to almost any crop, soil, terrain, region, and climatic conditions. Sprinkler irrigation technology has the characteristics of water conservation, time saving, land utilization, crop yield increase, and strong adaptability. When buying a sprinkler, it should be noted that 1. The sprinkler must meet the standard requirements: When selecting the sprinkler, you should first check whether the product meets the national standard, industry standard or local standard. The sprinklers that do not have national standards, industry standards, or local standards should have enterprise standards that are filed by technical supervision departments at or above the provincial level. 2. Sprinkler and pipeline pressure must meet the requirements of use: sprinklers and pipelines should be selected scientifically and rationally according to requirements of sprinkler irrigation. The quality of sprinkler operations depends not only on the performance of the sprinkler, but more importantly, the inlet pressure of the pipelines and branch pipes depending on the working pressure of the sprinkler assembly. It is the basis of sprinkler area design. 3. The supporting pipes and fittings must use qualified products: The supporting pipes and fittings used should meet the corresponding technical standards and have a full test report issued by a testing agency at or above the provincial level. During the use of the sprinkler, attention should be paid: 1. Preparation before use: 1 When using a V-belt drive, the spindle and the pump of the power machine must be parallel and the pulleys must be aligned. The center distance must not be less than 2 times the sum of the diameters of the two pulleys. When the water pump is connected with the power machine, it should be equipped with a common chassis, and the claw type elastic coupling can be used. Pay attention to the concentricity of the power machine main shaft and the water pump shaft. 2 The installation height of the pump (based on the surface of the suction tank) should be lower than the allowable vacuum height of 1 to 2 meters. The soil at the job site should be solid to prevent collapse or fall into the ground. 3 Intake pipe installation should pay special attention to prevent air leakage. The filter should be completely submerged in water, its depth is about 0.3 meters, and keep a certain distance from the bottom of the pool and the wall of the pool to prevent inhalation of impurities such as sediment and air. 4 When laying out the water pipe, the hose should avoid rubbing with stones, bark and other objects, avoid wheel rolling and pedestrian trampling, and do not contact the running parts. The hose should be rolled into a disc shape and never touch the ground. The hard pipe should be dismantled into a single section and prohibited from moving in multiple sections to prevent wear and damage to pipes and joints. The pipeline should avoid exposure and rain in order to prevent deformation or aging of the plastic pipe. 5 Support the sprayer on the ground. The end face of the sprayer joint should be set as far as possible, and then fix the sprayer. Install the spray head on the spray frame and check if the rotation of the spray head is flexible. Pull the rocker arm to see if the tightness is proper. Add the appropriate amount of oil to the rotating part. Then wipe the quick connector clean and connected. 6Before starting, check whether the direction of rotation of the pump shaft is correct and whether the rotation speed is uniform. There should be no abnormal phenomena such as jams or abnormal sounds. 7 Before starting the centrifugal pump, the pump should be filled with water until it is filled with water inlet pipe and pump body. 2. Precautions for use: 1 After the water pump starts, no water will be discharged for 3 minutes. Check the machine for shutdown. 2 If abnormal phenomena (noise, vibration, water drop, etc.) occur during operation of the pump, stop immediately. Pay attention to the temperature rise of the bearing. The temperature must not exceed 75°C. (3) Observe whether the nozzle works normally, whether there is uneven rotation, too fast or too slow, or even no rotation phenomenon. Observe that the steering is flexible and there are no abnormalities. 4 Sprinkler irrigation should be avoided using water sources with high sediment content, otherwise the nozzles of pump impellers and nozzles can easily be worn out. When adjusting the nozzle speed, you can tighten or loosen the rocker spring to achieve. The rocker arm is suspended on the rocker shaft and can be rotated to adjust the depth of water entering the head of the rocker arm to control the spray head speed. Adjusting the reversal position can change the rotation speed. The sign of 5 nozzle speed adjustment is to use slow rotation speed as far as possible without generating surface runoff. Generally, the small nozzle rotates 1 cycle from 1 minute to 2 minutes, and the middle nozzle rotates 1 cycle from 3 minutes to 4 minutes. Sprinklers make 1 lap from 5 minutes to 7 minutes. 3. Unit maintenance. 1 Loose parts of the unit should be tightened in time. 2 Lubricate the lubrication parts on time to ensure good lubrication and normal operation. The maintenance of the power unit and the water pump of the 3 units shall be carried out in accordance with the relevant operating instructions. When the unit is stopped for a long time, the water in the pump body must be drained, the water pump and nozzle should be dismantled, the water stain should be wiped clean, and the oil should be assembled and assembled. The import and export parts should be wrapped and stored in a dry place. The pipe should be washed and dried (the hose is coiled into a disk) and placed in a cool and dry place. Do not store the above parts in places with high pH and high temperatures. 5 Threads (or quick connectors) and rust-prone areas on the frame should be properly oiled.
