FY type Chemical Centrifugal Pump corrosion-resistant stainless steel liquid sewage

FY type Chemical Centrifugal Pump corrosion-resistant stainless steel liquid sewage

Product Description

FY series of liquid pump is the unit in the traditional corrosion-resistant liquid pump on the basis of the integration of Switzerland Sulzer similar products of advanced technology, improved design and production of new pumps; the pump to eliminate the other commonly used liquid pump Mechanical seal and the selection of a unique structure of the impeller, so that the pump energy efficient, no leakage, long life, which is widely used in petroleum, chemical, pharmaceutical, paper, metallurgy, sewage treatment and other industries.

FY-type stainless steel liquid pump ┃ liquid chemical pump under conditions:

1. The temperature of the conveyed medium is -20-140 ° C.
2. Cast iron material pump, medium PH value in the range of 5-9.
3. The use of open-type impeller pump, the liquid contained in the liquid particle diameter to do not exceed the pump population diameter of 30% is appropriate.

FY-type stainless steel liquid pump ┃ liquid chemical pump Features:

1. The pump is a vertical structure, beautiful appearance, directly installed in the transport medium storage, no additional footprint, thereby reducing the infrastructure investment.
2. Elimination of the mechanical seal, to solve the other liquid pump due to mechanical seal easy to wear and often need to repair the trouble, saving the pump operating costs and improve work efficiency.
3. The use of a unique centrifugal double-balanced impeller for the delivery of solid particles and other clean media, low vibration and high efficiency, high efficiency; open double-balanced impeller for the transport is not clean with solid particles and short fibers Liquid, running smoothly, no clogging.

FY-type stainless steel liquid pump ┃ liquid chemical pump instructions:

Disassembly and assembly

1. If you replace or inspect the impeller, close the outlet valve, remove the flange connecting bolts and the bottom plate connecting bolts, and lift the pump with the lifting tool.
2. the bottom plate on the bracket, remove all the bolts of the pump, remove the pump cover and impeller nut, with a double hammer flick the pump, you can remove the impeller.
3. Replace the rolling bearing or packing, then the bottom plate does not move, as long as the removal of the motor and the corresponding bracket, remove the pump coupling, gland, round nut, remove the bearing body. To replace the packing, first remove the packing gland, and then remove and replace the filler.
4. assembly and disassembly in the opposite order, we must pay attention to the concentricity of the accessories on the shaft.

Installation, use, maintenance

1. pump assembly, the disk coupling to see if the rotation is flexible. Check whether there is metal friction sound, the parts nut is tight.
2. check the pump shaft and motor shaft concentricity, the coupling between the two shaft can not exceed the number of 0.1mm, the balance between the two shafts to maintain 1 ~ 2.5mm.
3. the suction pump to the bottom of the container between the distance of 2 to 3 times the suction diameter, the pump from the wall is greater than the aperture of 2,5 times.
4. the pump out of the pipeline, should be another bracket support, its weight is not allowed to support the pump.
5. check the direction of rotation of the motor, so that the direction of rotation of the pump in line with the direction indicated.
6. close the outlet pipe on the gate valve and pressure gauge, connected to the cooling water pipe.
7. start the motor, open the pressure gauge, and slowly open the outlet pipe valve to the required position, put into normal operation.
8. often check the pump and the motor, the bearing temperature should not exceed 75 ℃, the bearing box should be added enough butter.
