Abstract
Centrifugal pump of horizontal axis is without rinsing axle envelope.This utility model belongs to fluid conveying machine technical field, is specifically related to the gland seal device without flushing of a kind of centrifugal pump of horizontal axis.The assembly that K-type seals it is set with on this device axle sleeve in being positioned at annular seal space body, oil seal ring is loaded between K-type seals, sealing and be provided with the fuel filler neck guiding oil seal ring on cavity, the entrance sealing cavity loads the pressure end of gland, and gland is bolted and is sealing on cavity and compressing K-type sealing.This utility model simple in construction, reasonable in design, processing is simple, easy accessibility, effectively solves in the case of conveying in hydropenia environment has the medium of impurity and is not required to rinse, and controlled leakage amount reduces operating cost.
Description
Technical field
This utility model belongs to fluid conveying machine technical field, is specifically related to the gland seal device without flushing of a kind of centrifugal pump of horizontal axis.
Background technology
Centrifugal pump of horizontal axis is wide in the application of various fluid conveying industries.General horizontal centrifugal pump shaft envelope has two kinds, and the first is mechanical seal, and the second is that conventional filler seals.Two kinds seal maximum difference and are: mechanical seal, advantage is to seal reliably, few leakage rate can be controlled, even zero leakage, shortcoming is that structure is complicated, and installation accuracy requires higher, it is not suitable for the medium having impurity, need to wear the aid system of complexity, cost intensive, the aid system price that axle seals and wears sometimes has exceeded the price of centrifugal pump；Conventional filler seals, and advantage is simple in construction, and installation requirement is relatively low, and shortcoming is to be not easily controlled leakage rate, it usually needs flushing liquor (usually room temperature clean water) cools down, the easy pollution medium of flushing liquor, and consumption is bigger.
In part water-deficient area, when conveying has the medium of impurity to select conventional filler to seal, use room temperature clean water will produce the operating cost of costliness as flushing liquor.When leakage rate is big, expend relatively big, and easily pollution medium, cause leakage after mixing with medium, environment is produced and pollutes.
Summary of the invention
The purpose of this utility model is to provide a kind of centrifugal pump of horizontal axis without the gland seal device rinsed, and its simple in construction, reasonable in design, processing is simple, easy accessibility, effectively solve and be not required to rinse in the case of carrying the medium having impurity in hydropenia environment, controlled leakage amount, reduces operating cost.
Realizing the concrete technical scheme that this utility model above-mentioned purpose takes is: be set with the assembly that K-type seals on the axle sleeve in being positioned at annular seal space body, oil seal ring is loaded between K-type seals, seal and be provided with, on cavity, the fuel filler neck guiding oil seal ring into, the entrance sealing cavity loads the pressure end of gland, and gland is bolted and is sealing on cavity and compressing K-type sealing.
The external diameter that described K-type seals is interference fit with the endoporus of sealing cavity, and K-type seals endoporus rubber part elastic deformation and holds tightly with axle sleeve.
Being provided with pad between gland and the K-type sealing pressed, the cavity size and the conventional filler sealing cavity that seal cavity are equivalently-sized, and the K-type of oil seal ring both sides seals and is all two one-tenth one group.
The beneficial effects of the utility model are: simple in construction, it is easily installed, dismantles, it is a kind of without rinsing reliable axle envelope, effectively solve the demand being not required to rinse under hydropenia environment, the leakage rate of controllable shaft envelope, the problem simultaneously solving conventional filler flushing liquor pollution medium, adds sealing multiformity, reduces the cost of operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: axle sleeve 1, sealing cavity 2, K-type sealing 3, oil seal ring 4, fuel filler neck 5, pad 6, gland 7, bolt 8, nut 9.
Detailed description of the invention
Installing two groups of K-types in axle sleeve 1 and sealing cavity 2 and seal 3, it is interference fit that K-type seals the external diameter of 3 with the endoporus of sealing cavity 2, and K-type seals 3 endoporus rubber part elastic deformations and holds tightly with axle sleeve 1.Oil seal ring 4 is arranged on axle sleeve 1, seal between 3 two groups of K-types, two groups of K-types seal 3 again be arranged in sealing cavity 2, pad 6 is arranged in sealing cavity 2, gland 7 is inserted in sealing cavity 2, and end face is pressed on pad 6, and gland 7 has bolt hole, it is fixed on sealing cavity 2 by bolt 8 and nut 9, fuel filler neck 5 is finally installed.During utilization, first passage fuel filler neck adds minimal amount of grease, keeps K-type to seal 3 and is not burnt out by friction, and the degree of tightening of adjusting nut 9 simultaneously controls leakage situation.
