FY type liquid pump product characteristics
A. The pump is a vertical subaqueous pump with beautiful appearance. It is directly installed on the storage container of the medium to be transported without additional occupation area, thus reducing the investment in capital construction.
B. The mechanical seal is cancelled, which solves the trouble that the mechanical seal of other subaqueous pumps is easy to wear and must be maintained frequently, saves the operation cost of the pump and improves the work efficiency.
C. Adopt centrifugal double balance impeller for conveying clean medium without solid particles, with low vibration noise and high efficiency;Adopt open double balance impeller for conveying unclean liquid with solid particles and short fibers, running smoothly and without blocking.

Installation, use and maintenance of FY series submerged pumps:
Subaqueous pump in the process of use will encounter a lot of vertical subaqueous pump common problems, so we do the following 8 points before the use of installation to reduce the use of problems.
1. After the assembly of the pump, the disc moves the coupling to see whether it can rotate flexibly.Check whether there is metal friction sound, the screw parts are tightened.
2, check the concentricity of the pump shaft and the motor shaft, the difference between the upper and lower coupling outer circle shall not exceed 0.1mm, and the coupling end face clearance shall be maintained 1-2.5mm.
3. The distance between the suction inlet of the pump and the bottom of the container is 2~3 times of the suction caliber.The distance between the pump body and the wall should be greater than 2.5 times of the caliber.
4. The liquid outlet line of the pump should be strung out with a separate bracket, and its weight is not allowed to be supported on the pump.
5. Check the rotation direction of the motor, so that the rotation direction of the pump conforms to the indicated direction.
6. Close the gate valve on the outlet pipe and connect the cooling water pipe.
7. Start the motor, slowly open the idle valve of the outlet pipe to the desired position, and put it into normal operation.
8, often check the pump and motor.The temperature rise of the bearing should not exceed 75℃, and enough butter should be added in the bearing box.
