Abstract
Disclosed is a full antiseptic centrifugal pump, comprising a pumping casing, a pump cover and a connecting board. The pump cover is in corresponding connection with the pump casing, and the connection surfaces all employ eyelet pre-provided on the inner layer of plastic to strengthen the strength of the pump. The pump casing and the pump cover all employ double pointed nails, and add injection molding nuts to be tightly pressed, and thereby avoiding the metal being exposed outside. The opposite side of the pump casing employs metal inserts pre-buried in the inner layer of plastic, and a plurality of holes and internal hexagonal wrench bolts are fixedly connected via bolts, the holes are arranged in the center of the connecting board. A plurality of screwed holes which are provided on the outermost ring of the connecting board are fixedly connected with the bearing base likewise via bolts, thereby prolonging the service life of the apparatus, saving the repair time and avoiding the waste of the apparatus.
Description
The utility model relates to a kind of centrifugal pump, be meant a kind of full antiseptic project plastic centrifugal pump especially, the be corrosive occasion of liquid of the various band fine graineds such as dilute sulfuric acid, rare nitric acid, phosphoric acid, hydrochloric acid, hydrofluoric acid, fluoride salt, waste water, sewage that are applicable to chemical industry and non-ferrous metal platform refining industry.
Engineering plastics clamp plate type centrifugal pump in the prior art is made up of critical pieces such as pump case, pump cover, front plate, rear plate, discharge connections.The shortcoming of this pump is: front plate, discharge connection and connecting cleat and outlet are metallic material by the bolt of pipe, and all expose outside, are corroded easily and influence working life; Have only for this pump is equipped with a discharge connection and just can install and use, both increased the spare part burden of pump, increased a seal leakage point again.When the damage of the impeller in the pump chamber needs to change, must pull down discharge connection earlier, pull down the clamping plate connecting bolt again, maintenance is wasted time and energy; Each part pump head, be pump case, pump cover, clamping plate that the front and back clamping plate are combined and the clamping plate of another auxiliary pump head can not change mutual usefulness arbitrarily, the attachment hole of pump clamping plate is that pump case, pump cover, front and back clamping plate are combined two holes of subdrilling through processing, bore six holes in addition after tightening with bolt again, therefore after a clamping plate corrosion, another piece clamping plate are also scrapped thereupon, the clamping plate that reconfigure be difficult to pump case on boring match.

A kind of complete anticorrosion centrifugal pump is connected to form successively by pump cover 2, pump case 1, connecting plate 3, and described pump case 1 is an integral structure with outer pipe 5, and pump case 1 and pump cover 2 are become by ultrahigh molecular weight polyethylene.
Complete anticorrosion centrifugal pump described in the utility model, wherein pump case 1 edge offers several tapped holes 12, pump case housing internal layer is provided with an eyelet 11, the intensity of sealing with increase, the one side middle part of pump case inwardly forms recess, the another side of pump case is along circumferentially being evenly equipped with several metalworks that is threaded the hole 13, and the center of pump case has through hole.
Complete anticorrosion centrifugal pump described in the utility model, wherein be provided with the eyelet 21 that matches with pump case housing inner layer metal circle 11 in the pump cover 2, on its edge of the one side of pump cover, offer through hole 23 accordingly with the tapped hole 12 at pump case 1 edge, the one side middle part of pump cover 2 is provided with the projection that matches with recess of pump case, the another side middle part is provided with a projection 22 in addition, and should also be provided with eyelet 24 by the projection internal layer, and the center of pump cover has fluid intake.
Complete anticorrosion centrifugal pump described in the utility model, the edge of its connecting plate 3 are convex and are provided with several mesopores 32, are being provided with several corresponding deep holes 33 with above-mentioned mesopore 32 adjacents, are provided with several apertures 31 around the connecting plate central through bore.
Compare with the clamp plate type centrifugal pump in the prior art, the full antiseptic project plastic centrifugal pump of the utility model has following significant advantage: 1. the utility model is in light weight, and is simple in structure, specious, easy to maintenance; 2. because the tie point of pump case of the present utility model and pump cover and connecting plate comprises that the pump cover gland nut all adopts metal embedded part to be arranged on plastic layer, so both increase the join strength of pump, reached the effect of internal and external anti-corrosive again; 3. outer pipe of the present utility model and pump case are one-body molded, have both reduced the burden of user's spare part, have reduced by a seal leakage point again; 4. because pump case pump cover of the present utility model and connecting plate are shaping size, interworking use arbitrarily when therefore changing spare part; 5. because the utility model has adopted the metal embedded part setting, and pump case and pump cover make by the ultra-high molecular weight polyethylene engineering plastics, therefore solved outer problem of corroding earlier, the working life of having improved pump greatly.
