Abstract

The invention discloses a mechanical seal for a rotary shell pump. The mechanical seal comprises a non-compensation ring, a compensation ring, a compensation ring seat, a spring and a spring seat, wherein a pump shaft is sleeved with the non-compensation ring, the compensation ring and the compensation ring seat, the compensation ring is mounted on the compensation ring seat, the compensation ring seat is sleeved with the spring seat, and the spring is mounted between the spring seat and the compensation ring seat. The mechanical seal has the characteristics as follows: the whole seal is compact in structure, the number of parts is decreased, required axial space is reduced, and function and mounting requirements of the seal for the rotary shell pump are fully met.

Description

A kind of rotary case pump mechanical seal
Technical field
The present invention relates to mechanical seal field, be specifically related to a kind of rotary case pump mechanical seal.
Background technique
Rotary case pump is that a kind of structure and working principle are all very unique novelpump, because manufacturer and user understand very few to the feature of this pump and structural principle, thus use is at home less.But due to its advantages, all have broad application prospects in industries such as rubber, oil, chemical industry, metallurgy, food, papermaking, printing and dyeing, the volume of rotary case pump own is little, compact structure, therefore when being equipped with sealed product to rotary case pump, the axial dimension that sealing allows is very limited, brings certain difficulty to the design of sealing.
Summary of the invention
The object of the invention is to overcome above-mentioned not enough problem, a kind of rotary case pump mechanical seal is provided.
The technological scheme that the present invention is adopted for achieving the above object is: a kind of rotary case pump mechanical seal, comprise uncompensated ring, compensated loop, compensated ring adaptor, spring, spring seat, described uncompensated ring, compensated loop, compensated ring adaptor are sleeved on pump shaft, described compensated loop is arranged on compensated ring adaptor, described spring socket sleeve is contained on compensated ring adaptor, therebetween mounting spring.
Described compensated loop is embedded on compensated ring adaptor.
Described uncompensated ring is fitted on the shaft shoulder of pump shaft.
Described compensated ring adaptor is provided with lug, and described spring seat is provided with the groove with described lug corresponding matching.
Be provided with O type circle one between described uncompensated ring and pump shaft, described O type circle one is arranged in the O type ring recess that pump shaft is offered.
O type circle two is installed between described compensated ring adaptor and spring seat.
Feature of the present invention is: whole sealing configuration is compact, decreases the number of component, shortens required axial space, fully meets function and the installation requirements of rotary case pump sealing.
Accompanying drawing explanation
figure1 is structural representation of the present invention figure;
figure2 is that compensated ring adaptor of the present invention is connected with spring seat and illustrates figure.
Wherein: 1, uncompensated ring 2, O type circle 1, compensated loop 4, compensated ring adaptor 5, spring 6, O type circle 27, spring seat 8, O type circle 39, the pump housing 10, pin.
Embodiment
As figure1, shown in 2, the present invention includes uncompensated ring 1, compensated loop 3, compensated ring adaptor 4, spring 5, spring seat 7, described uncompensated ring 1, compensated loop 3, compensated ring adaptor 4 is sleeved on pump shaft, described compensated loop 3 adopts setting type structure, be embedded on compensated ring adaptor 4, sealing configuration is without the need to using throw-out collar, decrease the number of part, shorten axial space, described spring seat 7 is sleeved on compensated ring adaptor 4, therebetween mounting spring 5, spring 5 is to whole sealing redeeming, described uncompensated ring 1 is positioned on pump shaft, be pressed on the shaft shoulder of pump shaft by locking devices such as locking nuts, described spring seat 7 prevents from rotating by installing pin 10 with the pump housing, described compensated ring adaptor 4 is provided with lug 11, described spring seat 7 is provided with the groove 12 with described lug 11 corresponding matching, prevent from rotating with coordinating of groove by lug 11, ensure that whole collocation structure is in by said structure static, do not rotate with pump, O type circle 1 is installed between described uncompensated ring 1 and pump shaft, described O type circle 1 is arranged on the effect playing sealing in the O type ring recess that pump shaft is offered, O type circle 26 is installed between described compensated ring adaptor 4 and spring seat 7 seal, O type circle 38 is installed between described spring seat 7 and the pump housing 9 seal.
The whole sealing configuration of the present invention is compact, and required axial space is short, fully meets function and the installation requirements of rotary case pump sealing.
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technological scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
