FYS type engineering plastic corrosion-resistant liquid pump product overview

      FYS type engineering plastic submerged pump is the world's excellent corrosion-resistant material - fluoroplastic alloy. Our unit uses FYS type fluoroplastic submerged pump which is a vertical single-stage single-suction centrifugal pump with excellent anti-corrosion performance, high mechanical strength, no aging and no toxin decomposition. It is used to transport any concentration of acid, alkali, oxidant and other corrosive liquids which do not contain solid particles and are not easy to crystallize. Mainly solve the problem of strong corrosive medium transportation.

FYS type engineering plastic corrosion-resistant submerged pump product features

      FYS type fluoroplastic submerged pump is a vertical structure, the pump body and the impeller part are immersed in the liquid, so it occupies a small area, and the shaft seal has no leakage phenomenon, so it is suitable for the corrosive liquid with a medium temperature of -5 ° C to 105 ° C. . The steering of the pump should be started in the direction indicated by the pump. It cannot be reversed and the pump body must be submerged in the liquid at startup. A: Reinforced polypropylene. C: Polyvinylidene fluoride. D: fluoroplastic alloy

FYS type engineering plastic corrosion-resistant submerged pump use range

FYS type fluoroplastic submerged pump can transport acid, alkali, salt, oil, beverage and other media, widely used in chemical, petrochemical, fine chemical, dye chemical, instrumentation, light industry, metallurgy, textile, environmental protection, water treatment, Pharmaceutical, food and other departments.

FYS type engineering plastic anti-corrosion liquid pump material

1 In order to ensure the transport of different media and long life, there are five kinds of materials.

A: Reinforced polypropylene - corrosion resistant stainless steel FRPP-ICr18Ni9Ti

B: Reinforced polypropylene - titanium FRPP-Ti

C: reinforced polypropylene - true metal

D: reinforced polypropylene - fluoroplastic table

E: Reinforced polypropylene - acrylic coating

2 In addition to the shaft, the materials that come into contact with the medium are as follows: F-4, silicon hydride, silicon carbide, drinking alloy, reinforced polypropylene.

3 In order to prevent various problems caused by thermal expansion and contraction deformation, the connecting pipe of the pump is made of composite steel pipe.

The axial force and radial force generated in the operation of the 4FYS type fluoroplastic submerged pump are controlled by the adjustable bearing of the heart, ensuring stable operation and low noise.

5 The lower part of the pump is equipped with a water bearing. The pump with a depth of more than 1 m is equipped with an intermediate water bearing to ensure smooth and reliable operation of the pump.

FYS type fluoroplastic submerged pump disassembly and assembly

1. FYS type fluoroplastic liquid pump If the pump is replaced or inspected, the valve can be closed, the flange connecting bolt and the bottom plate connecting bolt can be removed, and the FYS type fluoroplastic liquid pump can lift the pump out of the container with a lifting tool.

2. Place the bottom plate perpendicular to the fixed bracket, remove all the bolts of the pump body, take out the pump cover and the impeller nut, and use the double hammer to lightly hit the pump body to remove the impeller.

3. FYS type fluoroplastic liquid pump replaces the flow bearing, the bottom plate does not move, as long as the motor and the corresponding bracket are removed, the pump coupling, the gland, the round nut are removed, and the shaft sleeve is taken.

4. The order of assembly and disassembly of FYS type fluoroplastic submerged pump is reversed. Pay attention to the concentricity of the accessories on the shaft.

FYS type engineering plastic corrosion-resistant submerged pump installation, use, maintenance

1. After assembling the FYS type fluoroplastic liquid submerged pump, turn the coupling to see if it is flexible. Check for metal friction and screw the components.

2. Check the concentricity of the pump shaft and the motor shaft. The left and right outer diameters of the upper and lower couplings must not exceed 0.1 mm, and the end face clearance of the coupling should be 1 to 2.5 mm.

3. The distance between the suction port of the FYS type fluoroplastic liquid pump and the bottom of the container is 2 to 3 times of the suction diameter. The distance between the pump body and the wall should be greater than 2.5 times the diameter.

4. The outlet pipe of the FYS type fluoroplastic submerged pump should be supported by a bracket, and its weight is not allowed to be supported on the pump.

5, FYS type fluoroplastic liquid pump to check the direction of rotation of the motor, so that the direction of rotation of the pump meets the direction of indication.

6. Close the gate valve on the outlet line and turn on the cooling water pipe.

7, FYS type fluoroplastic liquid pump under the motor, slowly open the outlet pipe gate valve to the required position, put into normal operation.

8. Always check the condition of the pump and motor of FYS type fluoroplastic liquid. The temperature rise of the bearing should not exceed 75 °C, and enough butter should be added in the bearing box.
