　　A: Due to the particularity of submerged fan under water, many years of cooperative customers often consult the problems of maintenance, maintenance and failure of submerged fan. Today, we will sort out and summarize the common faults and solutions of submerged fan and share them with you!

　　During operation of submerged fan, phenomena such as power failure, sudden stop in operation, no water supply, excessive current, obvious vibration and noise will occur. The problems will be analyzed and solutions will be found. If this article is likely to help you, please collect it. I will encounter these symptoms again later on with the submerged blower and turn this article directly out of my favorite folder for one-on-one diagnosis.

　　Power-on submerged fan can not start

　　1. Cause of failure

　　(1) Abnormal power supply.

　　(2) The supply voltage is too low.

　　(3) The power cable is broken and the plug is damaged.

　　(4) The power supply is out of phase.

　　(5) Loss of motor winding.

　　(6) Impeller is blocked and stuck by debris.

　　2. Solution

　　(1) Restart after the power supply is normal.

　　(2) In normal condition, the three-phase voltage of power supply is 350-400V and the single-phase voltage is 200-240V. Otherwise, try to restore before starting use.

　　(3) Replace damaged cables or plugs.

　　(4) Find out the missing phase and replace damaged switch, fuse and motor leads.

　　(5) Rewinding burnt winding.

　　(6) Remove foreign matters, but care must be taken not to destroy the balance of the impeller. Some of the central screws of the impeller are reversed, which should be paid attention to when removing.

　　Submerged fan

　　(7) The rotor and shaft are loose and slip.

　　2. Solution

　　(1) Press can not start the inspection process.

　　(2) Remove debris from the water filter screen.

　　(3) Check water outlet pipeline and treat it symptomatically.

　　(4) Adjust the position of submerged fan.

　　(5) Replace damaged sealing parts.

　　(6) Adjust any two-phase wiring of the power supply and change the phase sequence; Single-phase motor changes wiring.

　　(7) Eliminate loosening and slipping.

　　Excessive current in operation of submerged fan

　　1. Cause of failure

　　(1) Motor overload.

　　(2) Damage to seals of bearings, bushings, etc.

　　(3) Shaft bending.

　　2. Solution

　　(1) Adjust the pump head.

　　(2) Replace seals of the same specification.

　　(3) Re-correct shaft or replace it.

　　Increased vibration beyond allowable range

　　1. Cause of failure

　　(1) The fasteners in the fan are loose.

　　(2) The balance of motor rotor or impeller is destroyed.

　　(3) There are foreign matters in the rotating part.

　　2. Solution

　　(1) Check and tighten all fastening parts.

　　(2) Re-correct pump balance.

　　(3) Remove foreign matters.

　　"Buzzing" of submerged fan after energizing, but it does not work properly

　　1. Cause of failure

　　Capacitor damaged.

　　2. Solution

　　Replace the damaged capacitor, take care not to let the cooling oil in the pump overflow when replacing, and tighten the relevant screws.

　　In case of the above problems, check the submerged fan according to the solutions mentioned in this paper. If the problems are serious, consult the manufacturer for repair.

　　Because the submerged fan is installed under water, the maintenance in later period is tedious. To help customers solve the maintenance problems of submerged fan.
