Abstract
The utility model relates to a padding and mechanical sealing universal double entry pump and belongs to the field of sealing design of a pump. The padding and mechanical sealing universal double entry pump is suitable for a mechanical sealing pump cover and a padding box and a padding gland of a mechanical sealing pump body, and a rinsing water hole is formed in the side wall of the front end of the mechanical sealing pump cover; when padding sealing is selected, the padding box, the sealing padding and a water seal ring are sequentially arranged in a sealing cavity body, then the padding gland is pressed, and the rinsing water hole in the mechanical sealing pump cover is externally connected with water injection equipment; when mechanical sealing is selected, the padding gland, the padding box, the sealing padding and the water seal ring in the annular sealing cavity body are taken out, then the mechanical sealing is arranged, the rinsing water hole in the mechanical sealing pump cover is packed by a screw and a seal pad and the mechanical sealing is subjected to water injection by the rinsing water hole. According to the padding and mechanical sealing universal double entry pump, one pump can be suitable for various stations, the manufacturing cost is reduced and the maintenance is simple and fast.
Description
Technical field
The utility model relates to a kind of filler and the general double suction pump of mechanical seal, belongs to the Seal Design field of pump.
Background technique
Double suction pump is all widely used in social every profession and trade.Traditional double suction pump shaft seal mainly contains two kinds of forms, and the first is packing seal, simple in structure, low price, easy to maintenance, but leakage rate is large, power consumption penalty is large, and therefore packing seal is for delivery of general medium, as water etc.; Generally be not suitable for oil and chemical medium, particularly can not be used in valuable, explosive and poisonous medium.The second is the mechanical seal of fast development in recent years, and mechanical seal is effective, and leakage rate is very little, and the life-span is long, but price, processing installation and maintenance maintenance is higher than general seal request, and operation is comparatively complicated when safeguarding.
Conventionally Designer can select suitable shaft seal form according to requirements such as the applying working condition of pump, client's specific demands; due to the difference of these two kinds of sealing means; conventionally having different seal chambers coordinates with filler or mechanical seal; dissimilar seal chamber is equipped with the different pump housings, pump cover; cause so same pump when different operating modes, to have two kinds of different structural types; do not meet seriation, generalization, the standardization object of engineering goods, cause a lot of unnecessary troubles to manufacturer and client yet.
Model utility content
The purpose of this utility model is in order to solve, to adopt the pump housing of same structure, the double suction pump of pump cover, can be suitable for the shaft seal of mechanical seal and two kinds of forms of filler, to meet compatibility and the versatility of this pump under different Environmental Conditions simultaneously.
The purpose of this utility model is achieved through the following technical solutions:
A kind of filler of the present utility model and the general double suction pump of mechanical seal, comprise axle sleeve, stuffing box packing, mechanical seal, mechanical seal pump cover, the mechanical seal pump housing, Stuffing box, Gland;
Wherein, Stuffing box is that external diameter coordinates the annular solid that the annular seal space internal diameter forming matches, internal diameter and axle sleeve external diameter match with the mechanical seal pump housing with mechanical seal pump cover, and on ring part, be processed with the flushing water hole of radial aperture, the left end outer rim of Stuffing box extends radially outward out positioning table, and the inner chamber left end of Stuffing box is processed with the mounting groove matching with stuffing box packing external diameter;
The annular solid that Gland is that external diameter and stuffing box packing external diameter match, internal diameter and axle sleeve external diameter match, the left end outer rim of Gland extends radially outward out positioning table;
Mechanical seal pump cover front end side wall is processed with rinses water hole;
Mechanical seal pump cover and the mechanical seal pump housing are enclosed within respectively on the axle sleeve outside pump shaft, the ring packing cavity forming after mechanical seal pump cover coordinates with the mechanical seal pump housing; When gland seal assembly is selected packing seal, in the ring packing cavity forming after coordinating with the mechanical seal pump housing to mechanical seal pump cover, pack successively Stuffing box, stuffing box packing and seal cage into, in this ring packing cavity, be pressed into Gland again, by screw, Gland, Stuffing box, mechanical seal pump cover three axial compression are also circumferentially located, and the flushing water hole of seal cage, Stuffing box and flushing water hole that pump with mechanical seal covers are aligned, the external water injection equipment in flushing water hole that pump with mechanical seal covers; When gland seal assembly is selected mechanical seal, unload screw and take out Gland, Stuffing box, stuffing box packing and the seal cage in ring packing cavity, in this ring packing cavity, mechanical seal is installed, the place, flushing water hole covering at pump with mechanical seal is by screw and sealing gasket encapsulation, and mechanical seal is by the flushing water hole water filling carrying.
Beneficial effect
The double suction pump structure that a kind of mechanical seal that the utility model adopts and packing seal are exchanged, the manufacture pump housing, pump cover cost that packing seal cavitys different from mechanical seal cause have been greatly reduced, also make same pump can be applicable to many kinds of work position simultaneously, easy to maintenance quick.
