Abstract

The utility model discloses a new type of corrosion resistant plastic self-priming pump, comprising a pump body, a guide vane, an impeller, a rear cover, a mechanical seal, a static ring gland and a stent. A liquid storage box of the lower part of the pump body is circular arc-shaped. The pump body is formed without embedding any steel insert and is molded with full plastic. A curved casing of the pump body adopts an eccentric circular guide vane with odd-even or even-odd blades. The utility model has the advantages of smooth operation, corrosion resistance, quick self-priming speed, energy conservation, high work efficiency and long service life etc.

Description

Novel corrosion resistant plastics self-priming pump

Technical field:

The utility model relates to a kind of novel corrosion resistant plastics self-priming pump, especially is applicable to the plastics self-priming pump of chemical field.

Background technique:

Existing plastics self-priming pump, the gas-liquid separated principle of main utilization, the front shroud of the pump housing, outer pipe portion and fluid storage tank adopt soft non-return lift and packing ring (generally all having rubber to make), prevent the refluence and the sealing of non-return liquid, it is too urgent that purpose is that buffering liquid refluxes, the fluid low of fluid storage tank, cause the self-priming difficulty, the structure bottom utilization return port device of the pump housing of existing pump, meet the easily material of precipitation, crystallization, cause phenomenons such as self-priming difficulty, gas-liquid separation are unclear, liquid superheat, non-fluid easily; Because the intensity of plastics can not be compared with metal strength far away, bury steel inserts outsourcing plastic stempressing in the attachment portion, pump housing both sides of at present main plastics self-priming pump all has and make.Because pump housing both sides connect metal insert is arranged all, form with soft non-return lift, packing ring, thereby it is loosening the corrosion of pump housing metal insert to have occurred under the condition of ever-changing, complicated chemical medium at present, cause pickling, working life is short, damage easily, owing to adopt rubber to do safety check and sealing gasket in the pump, thus can not adapt to the condition restriction such as conveying of some chemical mediator.

Summary of the invention:

The utility model corrosion resistant plastics self-priming pump has overcome deficiency of the prior art, provide a kind of long service life, anticorrosion, self-priming speed is fast, self-priming degree of depth height, as long as select different plastics for use, can be anti-known chemical mediator at present.

The utility model corrosion resistant self-priming pump, comprise that the position fluid storage tank adopts circular arc type under the pump housing, stator, bonnet, seal end plate, mechanical seal, support, the described pump housing, any steel inserts is not buried in described pump housing moulding, made by overall plastic mold pressing, the housing of the described pump housing adopts odevity or the eccentric round stator of even odd-numbered blade.

The beneficial effects of the utility model are: the following position fluid storage tank of the pump housing adopts the circular arc type design, appearance looks elegant, generous, the storage liquid measure is big, any steel inserts is not buried in the moulding of the pump housing, make by overall plastic mold pressing, its appearance, also be that the revolutionary character of pump industry in carrying strong acid, highly basic, salt, various organic solvent breaks through, fundamentally thoroughly solved the narrow limitation of carrying various chemical mediators at Lower tank, economy, material benefit, reliable performance, safety, the long service life of whole pump is provided simultaneously; The curve housing of the pump housing adopts odevity or the eccentric round stator of even odd-numbered blade, has used outer mixing and the gas-liquid separation principle of combining in it, and self-priming speed is fast, inhale apart from high, save the energy, high working efficiency is owing to adopt the eccentric round stator of main impeller and stator odevity or even odd-numbered blade, impeller is under the effect of liquid, fluid is even, and it is little to cavitate, axially, radial force is balanced, vibrate little, advantage such as noise is low.

Embodiment:

7. 9. the utility model corrosion resistant self-priming pump be connected support by motor, again by directly 3. 5. 1. fixing on the support with the pump housing that the fluoroplastic mold pressing is made with seal end plate the pump cover after installing, 4. stator is loaded in the pump case that has locating stud, impeller is the motor-hollow axle of axle root and the Morse's taper that processes 2., 8. put mechanical seal 6. by the 12mm hanging bolt, hang tight and rotate with nut, thereby, blade in the impeller forces the fluid rotation, to the liquid work done, its energy is increased, liquid under the effect of the odevity of off-centre or the round stator of even odd-numbered blade, uniformly to around throw away, the impeller internal pressure just is lower than the pressure in the intake pipe, new liquid just is inhaled into impeller under this action of pressure, liquid constantly flows out in pump fast.

Claims

1. a novel corrosion resistant plastics self-priming pump comprises the pump housing, stator, impeller, bonnet, support, mechanical seal, seal end plate, it is characterized in that: one, and pump housing bottom fluid storage tank adopts circular arc type; Its two, any steel inserts is not buried in the moulding of the pump housing, is made by overall plastic mold pressing; Its three, the inner housing of the pump housing adopts odevity or the eccentric round stator of even odd-numbered blade.
