FSB horizontal fluorine plastic chemical pump for alkali / rare earth / pesticide industry pump

FSB horizontal fluorine plastic chemical pump for alkali / rare earth / pesticide industry pump

Product Description

FSB-type fluorine plastic alloy centrifugal pump designed according to international standards, the pump body with metal shell lined with perfluoro-propylene propylene (F46), pump cover, impeller and sleeve are covered with metal insert fluorine plastic overall sintering compression molding, The use of external corrugated pipe mechanical seal, static ring selection of 99% alumina ceramic or silicon nitride, dynamic ring using PTFE fill material, corrosion-resistant wear, suitable for conveying any concentration of sulfuric acid, hydrochloric acid, acetic acid, hydrofluoric acid, Nitric acid, aqua regia, strong alkali, strong oxidants, organic solvents, reducing agents and other harsh conditions of strong corrosive media, is the world's strongest one of the anti-corrosion equipment.

FSB type fluorine plastic alloy centrifugal pump design features:

FSB and FSB-D fluorine plastic alloy centrifugal pump flow components are all made of fluorine plastic alloy, compact structure, simple operation, low price, two models of the pump shell, impeller, machine seals, etc. are widely used by the majority of users Welcome.

FSB type fluorine plastic alloy centrifugal pump mechanical seal:

FSB and FSB-D Fluor plastics Alloy Centrifugal Pumps are the most advanced exterior-type tetrafluoroethylene bellows mechanical seals, which are designed to compensate for the radial runout of the pump shaft, single-face sealed exterior, easy handling, Anti-wear sealant performance, and has a multi-layer protection, to extend the life of the seal; for the transport of impurities containing corrosive media, can be equipped with no cooling water single-sided hard to hard (silicon carbide on silicon carbide) mechanical seal, Strong alkali and hydrofluoric acid and other special corrosive media with no pressure sintered silicon carbide seal; user selection to take into account the medium of the solid content and medium corrosion.

FSB type fluorine plastic alloy centrifugal pump instructions:

1. Start and stop
2. to the pump filled with liquid (cited).
3. check the stent oil tank is within the specified range of oil.
4. check the motor running direction, check the pump placed mark.
5. close the outlet valve and pressure gauge cocks.
6. start the motor, open the pressure gauge cocks, slowly open the outlet valve. When the pressure gauge pointer to the desired position, stop the water valve size adjustment.
7. need to stop, first turn off the water valve, and then cut off the power.

FSB type fluorine plastic alloy centrifugal pump disassembly and installation:

Removal of pump

1. Connect the pump to the motor with the jaw type coupling, and loosen the 4 connecting bolts of the bracket and the base when disassembling, so that the pump can be disengaged from the motor.
2. Loosen the connecting bolts of the back cover of the pump body.
3. Loosen the impeller shaft and the shaft of the pump shaft to connect the torsional bolts in the coupling.
4. Loosen the mechanical seal! No fixing screw, with the wooden hammer touch the center of the coupling bolt, impeller shaft and pump shaft Mohs taper release after pulling out the impeller, back cover, seal ring. Cover the cover with a gland screw.
5. Loosen the pump shaft left and right gland screws. Remove the pump shaft, the bearing, and the cleaning rack oil chamber.

Assembly

Press the tightening ring, the static ring, the rear cover, the gland, the impeller, the pump body, etc. in the reverse order of disassembly.

FSB type fluorine plastic alloy centrifugal pump Note:

Installation and precautions

1. Before installing the pump and motor should be checked, the parts should be intact, the pump no debris.
2. Place the pump in the horizontal position on the inlet, the pipe, and the power supply, and finally use the hand plate to move the coupling to check whether the rubbing phenomenon is easy and the installation is finished.
3. Plastic alloy centrifugal pump steel is worse than the metal, so the pipe weight can not be directly on the pump body, the inlet and outlet piping should be supported by the bracket.The light pump should also be installed in the exit check valve. Sudden downtime water hammer damage.
4. All joints must be kept sealed to prevent leakage, the liquid affects the pump performance.
5. If you find a move or an abnormal sound during operation, you should check the cause immediately.

Start and stop

1. Charge the pump with fluid (priming).
2. Whether or not the oil level of the oil chamber is within the specified range.
3. Check the direction of operation of the motor. Adjust the rotation mark of the pump.
4. Close the outlet valve and the pressure gauge cock.
5. Turn on the motor. Open the pressure gauge cock. Slowly open the outlet valve.
6. When the important stop, first turn off the water valve and then cut off the power.When the force gauge pointer points to the desired position, stop the adjustment of the outlet valve size.
