Description
Technical field
The utility model relates to the axle sleeve type spiral seal structure of a kind of sealing configuration of acid and alkali-proof pump motor shaft, particularly a kind of acid and alkali-proof pump.
Background technique
Acid and alkali-proof pump is main perishable equipment for liquid transportation.The sealing of traditional acid and alkali-proof pump adopts packing seal good more, and this sealing means shaft seal is very difficult, packing and axle sleeve quick abrasion, and change frequent, maintenance load is large, impact safety in production.The main cause of shaft sealing leakage have following some: 1, shaft seal physical dimension is unreasonable; 2, axial seal pressure is too high; 3, have particulate matter in shaft seal liquid, particulate matter is skewness in impeller channel, makes rotor produce vibration; The rebound elasticity of filler is poor; 4 start frequently.Therefore be necessary to carry out technological improvement to it.
Model utility content
The purpose of this utility model is the axle sleeve type spiral seal structure in order to the deficiency and a kind of acid and alkali-proof pump solving above-mentioned technology.
In order to achieve the above object, the axle sleeve type spiral seal structure of a kind of acid and alkali-proof pump designed by the utility model, be included in the axle sleeve through hole that the pump housing is offered, the one-body molded Stuffing box peripherally gone up at the collar extension of pump housing Upper shaft sleeve through hole, the axle sleeve of through described axle sleeve through hole and Stuffing box continuously, stuffing box gland is connected on axle sleeve, and the sealing gland be fixed on the outward opening opening's edge face of described Stuffing box and the multiple seal rings be placed between the inwall of described Stuffing box and axle sleeve, and the plurality of seal ring is horizontal along axle sleeve; Described axle sleeve is divided into forward and backward two-part, and the spiral chute be wherein cut with on the outer surface of rear section continuously, described spiral chute is corresponding with multiple seal ring.
The axle sleeve type spiral seal structure of above-mentioned a kind of acid and alkali-proof pump, axle sleeve described in its structure is divided into forward and backward two-part, and be cut with on the outer surface of rear section continuously spiral chute, axle sleeve by conventional monolithic improves helically stuffing box gland and common axle sleeve two-part, thus makes to form spiral seal structure between the seal ring in axle sleeve and Stuffing box with lift-off seal shaft seal effect.
The working principle of above-mentioned spiral seal is when axle sleeve together rotates with pump shaft, and sealing thread produces pumping pressure to the viscous fluid be filled in seal clearance, balances each other with by the pressure medium sealed, thus stops fluid to leak.
As further technological improvement, have additional one oil sealing in the outside of above-mentioned sealing gland.When above-mentioned further improvement opportunity scheme Zhong Gai road oil sealing can prevent acid and alkali-proof pump from stopping transport, pressured fluid medium oozes out from axle sleeve and sealing gland gap location between the two.
As further technological improvement, the joint of the forward and backward part of above-mentioned axle sleeve has additional O-ring seals.This O-ring seals more further in Technological improvement plan both can prevent air inlet in the pump housing, can prevent again the forward and backward portion connection seepage of axle sleeve.
As preferably, the seal ring in above-mentioned selects graphite-seal ring.Described graphite-seal ring adopts flexible graphite belt or Expanded graphite establishment filler, and forming through mold pressing system, is a kind of typical seal that can directly buy.
After above-mentioned axle sleeve type spiral seal structure uses in acid and alkali-proof pump, the sealability of acid and alkali-proof pump pump shaft can be promoted significantly, thus significantly promote the routine use stability of acid and alkali-proof pump, and working life, economic benefit is good.
