What matters should be paid attention to in the use of sprinkler irrigation machine?

The weather is getting warmer, which also indicates that the planting season is coming soon. Have you made a detailed understanding of the sprinkler irrigation equipment? what should you pay attention to in the process of using the sprinkler irrigation machine?

1. Preparation before use

When ① adopts triangle belt transmission, the power engine spindle and water pump must be parallel, the pulley must be aligned, and the center distance should not be less than 2 times the sum of the diameters of the two pulleys. When the water pump is connected with the power engine, it should be equipped with a common chassis, and the claw type elastic coupling can be adopted. attention should be paid to the concentricity of the power engine spindle and the water pump shaft.

The installation height of the ② pump (based on the water surface of the suction tank) should be lower than the allowable vacuum height of 1 to 2 meters. The soil in the working position should be solid to prevent collapsing or falling into the ground.

The installation of ③ intake pipe should pay special attention to prevent air leakage. The filter should be completely submerged in water, with a depth of about 0.3 meters, and keep a certain distance from the bottom and wall of the pool to prevent the inhalation of impurities such as sediment and air.

When laying outlet pipes in ④, hoses should avoid friction with pebbles, bark and other objects, avoid wheel crushing and pedestrian trampling, and do not come into contact with running parts. The hose should be rolled up and moved in the shape of a plate and do not land on the ground. The hard pipe should be disassembled into single-section handling, and multi-section joint movement is prohibited to prevent wear and damage to the pipe and joint. Pipes should avoid exposure to the sun and rain to prevent plastic pipes from deformation or aging.

⑤ will support the spray rack on the ground, the end face of the spray rack joint should be placed horizontally as far as possible, and then fix the spray rack. Install the sprinkler on the spray rack, check whether the rotation of the sprinkler is flexible, open the rocker arm to see if its tightness is appropriate, and add appropriate amount of oil to the rotating part. Then wipe the quick connector clean and connect well.

Before starting ⑥, check whether the rotation direction of the pump shaft is correct, whether the rotation speed is uniform, and there can be no abnormal phenomena such as jam, abnormal sound and so on.

Before starting the ⑦ centrifugal pump, fill the pump with water and start after filling the intake pipe and the pump body.

two。 Matters needing attention when using

After starting the ① pump, there is no water coming out for 3 minutes, so it should be stopped for inspection.

If there are abnormal phenomena (noise, vibration, water drop, etc.) in the operation of the ② water pump, you should stop immediately and pay attention to the heating of the bearing, and its temperature should not exceed 75 ℃.

③ observes whether the sprinkler works properly, whether it rotates unevenly, too fast or too slowly, or even does not rotate. Observe whether the steering is flexible and whether there is any abnormal phenomenon.

④ should try to avoid using water sources with high sediment content for sprinkler irrigation, otherwise it is easy to wear out the impellers and nozzles of the pump. When adjusting the speed of the sprinkler, it can be achieved by tightening or loosening the rocker arm spring. The rocker arm is supported on the rocker shaft, and the adjusting screw can be turned to adjust the water entry depth of the rocker head to control the speed of the sprinkler. The speed can be changed by adjusting the position of the reverse.

The sign of ⑤ sprinkler speed adjustment is that under the premise of no surface runoff, slow rotation speed should be adopted as far as possible. Generally, the small sprinkler turns once in 1 minute to 2 minutes, the middle sprinkler turns once in 3 to 4 minutes, and the large sprinkler turns once in 5 to 7 minutes.

3. Maintenance of the unit

① should fasten the loose part of the unit in time.

② should lubricate the lubrication parts on time to ensure good lubrication and normal operation.

The maintenance of the power engine and water pump of the ③ unit shall be carried out in accordance with the relevant operating instructions.

When the ④ unit is out of use for a long time, it is necessary to release the water storage in the pump body, disassemble and check the pump and sprinkler, wipe off the water stains, apply oil and assemble, wrap the import and export parts and store them in a dry place. The pipe should be washed and dried (hose rolled into a plate) and placed in a cool and dry place. Do not store the above parts in a place with acid, alkali and high temperature.

Threads (or quick joints) and rust-prone parts on the ⑤ rack should be properly oiled and stored.
