The invention discloses a kind of fluoroplastics lining centrifugal pumps, including the pump housing, the pump housing side is provided with feeding inlet, the pump housing is provided with discharge port far from feeding inlet side, feeding pipe is connected between the pump housing and feeding inlet, discharge nozzle is connected between the pump housing and discharge port, the pump body is provided with lining, and the lining inside is provided with impeller.The present invention passes through setting anti-corrosion snap ring; feeding pipe is connect with feeding inlet when in use; again by the junction of anti-corrosion snap ring alignment feeding pipe and feeding inlet; stir yourself ring; make erosion resistant coating that junction be completely covered; finally tighten the wing nut on the outside of screw; fixed anti-corrosion snap ring; when anti-corrosion snap ring can unclamp wing nut after a period of use; replace with new anti-corrosion snap ring; the setting can flexibly be sealed feeding pipe and the gap of feeding inlet junction, and preventing centrifugal pump from working long hours causes strongly corrosion liquid in the pump housing to leak, and the pump housing is protected not to be corroded.
Description
Technical field
The present invention relates to centrifugation pump technical field, in particular to a kind of fluoroplastics lining centrifugal pumps.
Background technique
Fluoroplastics lining centrifugal pump is according to international standard and the Design Processing of nonmetal pump to be combined to produce.Fluoroplastics
The centrifugal pump of lining teflon pump housing uses metal shell liner perfluoroethylene-propylene (F46), and pump cover, impeller and axle sleeve are with outside metal insert
The integral sintered compression moulding of packet fluoroplastics, axle envelope use tetrafluoro packing material, and inlet and outlet are all made of the reinforcing of cast steel body.This pump is applicable in
In the sulfuric acid, hydrochloric acid, acetic acid, hydrofluoric acid, nitric acid, chloroazotic acid, highly basic, strong oxidizer, organic solvent, the reducing agent that convey any concentration
Etc. harsh conditions strong corrosive media, be at present in the world it is newest it is corrosion-resistant equipment one of.
After existing fluoroplastics lining centrifugal pump long-time use, corrosive liquids easily corrodes pipeline junction, causes
Liquid leakage, or it is adhered to lined inner wall, lining is caused to corrode, causes centrifugal pump reduced service life, while efficiency declines.
Therefore, it is necessary to solve the above problems to invent a kind of fluoroplastics lining centrifugal pump.
Summary of the invention
The purpose of the present invention is to provide a kind of fluoroplastics lining centrifugal pumps, pass through the feeding inlet and feeding pipe in centrifugal pump
Between be provided with anti-corrosion snap ring, easily corrode pipeline junction to solve corrosive liquids mentioned above in the background art, lead
The problem of causing liquid leakage.
To achieve the above object, the present invention provides the following technical solutions：A kind of fluoroplastics lining centrifugal pump, including the pump housing,
The pump housing side is provided with feeding inlet, and the pump housing is provided with discharge port, the pump housing and feeding inlet far from feeding inlet side
Between be connected with feeding pipe, discharge nozzle is connected between the pump housing and discharge port, the pump body is provided with lining, described
Lining inside is provided with impeller, and the lined inner wall is provided with discharge sump, is provided with anti-corrosion between the feeding inlet and feeding pipe
Snap ring.
Preferably, anti-corrosion snap ring bottom is provided with loose collar.
Preferably, the anti-corrosion snap ring is internally provided with erosion resistant coating, is provided with link block at the top of the anti-corrosion snap ring.
Preferably, the link block is internally provided with screw, is provided with wing nut on the outside of the screw.
Technical effect and advantage of the invention：By setting anti-corrosion snap ring, feeding pipe is connect with feeding inlet when in use,
Again by the junction of anti-corrosion snap ring alignment feeding pipe and feeding inlet, stir yourself ring makes erosion resistant coating that junction be completely covered, finally
Tighten the wing nut on the outside of screw, fixed anti-corrosion snap ring, when anti-corrosion snap ring can unclamp wing nut after a period of use, more
New anti-corrosion snap ring is changed, which can flexibly be sealed feeding pipe and the gap of feeding inlet junction, prevent from being centrifuged
Pump, which works long hours, causes strongly corrosion liquid in the pump housing to leak, and protects the pump housing not to be corroded, has also ensured the peace of staff
Entirely, while the discharge sump of liner surface can reduce the contact area of liquid and lined inner wall, and liquid is prevented to be attached to lining for a long time
In inner wall, cause lining to be corroded.
Detailed description of the invention
Fig. 1 is overall structure diagram of the invention.
Fig. 2 is anti-corrosion Snap ring structure schematic diagram of the invention.
In figure：1 pump housing, 2 feeding inlets, 3 discharge ports, 4 feeding pipes, 5 discharge nozzles, 6 linings, 7 impellers, 8 discharge sumps, 9 anti-corrosions
Snap ring, 10 loose collars, 11 erosion resistant coatings, 12 link blocks, 13 screws, 14 wing nuts.
