The unit's water intake duct design is unreasonable or uncomfortable with the crew, the depth of the water pump is not submerged, and the order of the crew of the unit and the order of stopping the machine will worsen the water inlet conditions, generate vortex, and induce the vibration of the crew or the pump room. At the beginning of the crew that destroys the siphon vacuum, the air of the horn peak section is difficult to form a siphon time for a long time; The reasons of uneven sinking of water pumps and motors or poor rigidity of the foundation will also cause the unit to vibrate.

When users choose the pump, it is best to go to the sales point recognized by the agricultural machinery department. We must recognize the manufacturer. It is recommended to give priority to buying a water -filled diving pump, and see the card number and product quality qualification certificate. Do not buy "Three None" (

That is, there are no manufacturers, no production date, and no production license) products, otherwise problems will have problems, and users will be helpless.

As a user, because of the limitation of professional knowledge, it is difficult to determine. The best way is to consult experts in the pump. You may wish to consult some old pump users, especially those who are similar to their own use conditions. Reliable and mature products are a wise choice. At the same time, you should decide to use single -phase pumps or three -phase pumps according to the local power supply.
