Sprinkler use and maintenance precautions
Precautions for 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 should be carried out according to the relevant instructions.
4 When the sprinkling irrigation unit is stopped for a long time, the water in the pump body must be drained, the water pump and sprinkler should be dismantled, the water stain should be wiped clean, the oil coating and assembly should be done, and the import and export package should be kept and stored in a dry place. Pipes should be washed and dried. Tubes should be coiled and placed in a cool, dry place. Do not place the above parts in places with acid and alkali and high temperatures.
5 Threads or quick connectors and rust-prone areas on the rack should be properly oiled.
Precautions when using:
1 After the pump is started, no water is produced for 3 minutes. Check the machine for shutdown.
2 If abnormal phenomena occur during the operation of the pump - noise, vibration, water drop, etc., it should be stopped immediately. Pay attention to the temperature rise of the bearing. Its 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 if there is too much sediment content, otherwise the impeller of the pump impeller and the nozzle of the sprinkler head will be easily worn, and the growth of the crop will be affected.
5 In order to adapt to different soil quality and crops, nozzles need to be replaced. When adjusting the rotation speed of the nozzles, the rocker springs can be tightened or relaxed. The rocker arm is suspended on the rocker shaft and can also be rotated to adjust the water depth of the rocker arm head to control the spray head speed. Adjusting the reversal position can change the reversal speed.
6 The sign of good nozzle speed adjustment is to use slow rotation speed as far as possible without generating surface runoff. Generally, the small nozzle rotates 1 cycle in 2 minutes, and the medium nozzle rotates in 1 cycle in 3 minutes to 4 minutes. Sprinklers turn for 5 minutes - 7 minutes.
