Trois exigences pour le fonctionnement de l'équipement d'irrigation par aspersion

The equipment used in sprinkler irrigation projects mainly includes sprinkler machines, water pumps, power machines, nozzles, and other major engineering equipment, as well as auxiliary equipment such as control, pressure regulation, safety protection, measurement, and electrical control. The requirements for the operation and management of engineering equipment during the operation of sprinkler systems are as follows.
1、 General requirements for the operation of sprinkler irrigation equipment
Avant que le projet global d'irrigation par aspersion de l'équipement d'irrigation par aspersion ne soit mis en service, les procédures d'exploitation et les exigences doivent être préparées pour chaque type d'équipement en fonction du manuel du produit et des conditions de conception. Le système d'irrigation par aspersion doit fonctionner conformément aux procédures d'exploitation, au plan d'utilisation de l'eau et au groupe d'irrigation rotatif. Lorsque le système est en marche, il doit fonctionner en fonction de la pression de travail conçue de l'ingénierie des gicleurs, et en même temps, il doit fonctionner dans la plage de vitesse du vent conçue. Si la vitesse du vent de conception est dépassée, il est facile de provoquer des fuites et une mauvaise uniformité, ce qui affecte la qualité de pulvérisation de l'ingénierie des gicleurs. Pendant le fonctionnement des projets d'irrigation par aspersion, des notes de fonctionnement soigneuses doivent être prises, y compris le temps de fonctionnement de l'équipement, la pression et le débit de fonctionnement du système, la consommation d'énergie, le dépannage, la charge, le personnel de service et d'autres situations, et l'état de fonctionnement de l'équipement d'arrosage doit être régulièrement vérifié.
1. Preparation work for sprinkler equipment operation
Before running the sprinkler irrigation equipment system, it is necessary to check whether the status of each major equipment is normal. For example, whether the water pump turning gear is flexible and without noise, whether the long shaft deep well pump is filled with an appropriate amount of pre lubricating water, whether the leakage protector is sensitive, whether the three-phase voltage is normal, whether the diesel engine oil level is appropriate, whether the cooling water and diesel are sufficient, whether the control valve operation is flexible and in the closed position, whether the pressure gauge, vacuum gauge, and water gauge are normal, and whether the field mobile pipeline or unit has been set up.
2. Startup of sprinkler equipment system
The start-up of sprinkler equipment systems should be strictly carried out in accordance with the sequence of operating procedures. Before starting the centrifugal pump, all valves on the suction pipeline of the water pump should be opened, and the control valve on the discharge pipeline should be closed to ensure that the power machine starts under no load or light load. After starting, attention should be paid to observing whether the indicated values of the ammeter, vacuum gauge, and pressure gauge are normal, whether the sound of equipment operation is normal, and whether the speed regulation and exhaust of the diesel engine are normal. If there are any abnormalities, the vehicle should be stopped immediately for inspection. After confirming normal startup, slowly open the control valve on the outlet pipeline to supply water to the pipeline network.
3. Normal operation of sprinkler systems
After the sprinkler system enters normal operation, it is necessary to regularly check whether the indicated values of voltage, current, pressure, vacuum degree, etc. are normal. Check whether the temperature of the motor and bearings has increased, whether the dripping amount of the water pump packing is appropriate, and regularly check the blockage situation. When the spraying is completed and the previous irrigation area is rotated to the next irrigation area, the new working condition should be checked to see if it is normal. Pay attention to judging whether the system is working properly based on the spray pattern and atomization status of the nozzle. The operation of large sprinkler irrigation machines should be regularly monitored, and the towers should be kept in a straight line during operation.
