IHF type fluorine plastic chemical centrifugal pump is a single-stage single-suction fluorine plastic alloy chemical centrifugal pump, which is designed and produced according to the national standard and combined with the processing technology of non-metallic pumps. The pump has the advantages of corrosion resistance, wear resistance, high temperature resistance, no aging, high mechanical strength, no toxin decomposition, wide temperature range, and the transmission medium temperature is -85 ℃ ~ 200 ℃. The pump is widely used in chemical, pharmaceutical, petroleum, metallurgy, electric power, electroplating, pickling, pesticide, paper and other industries in liquid transportation, wastewater treatment and acid addition process.
Structural features
The pump body is lined with polyethylene glycol propylene (F46) in a metal shell, the impeller and pump cover are all made of metal inserts and coated with fluoroplastic integral sintering and pressing molding, the shaft seal is made of externally mounted bellows mechanical seal, the static ring is made of 99.9 alumina ceramic or silicon carbide, and the moving ring is made of tetrafluoro filling material or silicon carbide. It is characterized by advanced and reasonable structure, strong corrosion resistance, tight and reliable sealing performance, stable operation, low noise and long service life.
Main use
Can transport any concentration of sulfuric acid, hydrochloric acid, nitric acid, acetic acid, hydrofluoric acid, strong alkali, strong oxidant, organic solvents and other strong corrosive media. It is one of the more advanced corrosion-resistant water pumps.

Disassembly and assembly
(1) If the impeller is replaced or checked, the outlet valve can be closed, the flange connecting bolts and the bottom plate connecting bolts can be removed, and the pump can be lifted out of the container with a lifting tool.
(2) hang the bottom plate on the bracket, remove all the bolts of the pump body, take out the pump cover and impeller nut, and tap the pump body with a double hammer to remove the impeller.
(3) for the replacement of rolling bearings or packing, the bottom plate does not move, as long as the motor and the corresponding bracket, remove the pump coupling, gland, round nut, take out the bearing body. To replace the packing, first remove the packing gland, then remove and replace the packing.
(4) The order of assembly and disassembly NB,0 is opposite, and the concentricity of the accessories on the shaft must be paid attention.
Installation, use and maintenance
1. After the pump is assembled, turn the coupling to see if it rotates flexibly. Check whether there is metal friction sound and whether the nuts of each component are tightened.
2. Check the concentricity of the pump shaft and the motor shaft. The left and right difference of the outer circle of the two couplings shall not exceed 0.1mm, and the gap between the end faces of the two couplings shall be kept at 1~2.5mm.
3. The distance between the suction population of the pump and the bottom of the container is 2 to 3 times the suction caliber, and the distance between the pump body and the container wall is greater than 2,5 times the caliber.
4. The outlet pipe of the pump shall be supported by another bracket, and its weight is not allowed to be supported on the pump.
5. Check the rotation direction of the motor to make the rotation direction of the pump conform to the indicated direction.
6. Close the gate valve and pressure gauge on the outlet pipeline and connect the cooling water pipe.
7. Start the motor, open the pressure gauge, slowly open the gate valve of the outlet pipe to the required position, and put the person into normal operation.
8, often check the pump and motor, bearing temperature rise should not exceed 75 ℃, bearing box should add enough butter.
-
1. pump does not start
1, power failure: should check the power switch and wiring.
2, motor wiring failure: should check the motor connection.
Internal blockage of the pump: check whether there is foreign matter in the pump.
4. Motor failure: check whether the motor is damaged.
Water output of 2. pump decreases
1, pump drum cavity leakage: should check the shaft seal, sealing ring and valve is damaged.
2. Inlet valve leakage: check whether the valve sealing ring is damaged.
3. There are foreign bodies in the pump cavity or friction or blockage in the pump: check whether there are foreign bodies in the pump and clean up the deposits in the pump.
Excessive noise during operation of 3. pump
1. The pump chassis is not in close contact with the bracket: the bracket should be reinstalled or replaced.
2. The contact between the pump drum cavity and the pump body is not close: the axial clearance should be adjusted to ensure close contact.
3, bearing damage or foreign matter into: the bearing should be replaced.
4. pump temperature rise
1, pump fire or burn out: should check whether the pump is damaged, replace the undamaged parts.
2, bearing damage or poor lubrication: should check the bearing and lubrication system, replace the bearing, strengthen lubrication.
The above are the common faults of submersible pumps and their solutions. Users should pay attention to regular maintenance and maintenance when using submersible pumps, and eliminate them in time according to specific faults. This can extend the service life of the submerged pump and ensure production safety.
