Abstract
The utility model provides a universal layer shear type sealing for pumps, which can be widely applied to the existing pump class. The utility model has the advantages that smoke-running and dropping-leaking can be effectively controlled, and the generation of the leakage can be largely reduced. The utility model is characterized in that two bottom rings 1 are arranged at both ends of a material filling box; the two bottom rings 1, a shaft rod 3 and the material filling box are filled with semi-solid state sealing filling material 2.
Description
The utility model belongs to sealing industry (spare part in common use) class, is that a kind of pump seals with stratified shear specifically.
The pump type seal technology is divided into following two kinds through derivation for a long time: 1. packing class sealing: this type of sealing selects for use material woollen yarn knittings such as asbestos, graphite, rubber to form rope form, by packing axle and pump housing tension force is reached sealing effect.Deficiency: by leaking heat radiation, water consumption, power consumption (friction); 2. mechanical seal: this series products is two solid-state sealing surfaces from the fifties invention so far, by producing sealing in the efficient rotation, can reach fully and not leak.Its deficiency is: extensively adopt mechanical seal so far in petrochemical industry, with body of stainless steel, silicon carbide, materials such as graphite are friction ring, and to solid granulates medium rapid wear, size requirement is accurate, need see figure and customized, cost an arm and a leg.
The purpose of this utility model then is the problem at above-mentioned existence, has designed a kind of general pump that extensively is suitable for the existing pump class and has sealed with stratified shear, and it can control evaporating, emitting, dripping or leaking of liquid or gas effectively, the extensive generation that reduces leakage.
The utility model technical solution: a kind of pump seals with stratified shear, it is characterized in that being provided with two base rings 1 at the Stuffing box two ends, is filled with semisolid stuffing box packing 2 in two base rings 1 and axostylus axostyle 3 and Stuffing box.
The utility model has following advantage compared to existing technology:
1. need not washing solution, water saving;
2. internal shear surface friction drag is little, economize on electricity;
3. the axle sleeve that do not wear and tear, protection equipment;
4. existing equipment is not had required precision, adapt to wide;
5. reduced to leak and produced.
Fig. 1 is the utility model structural representation.
Below in conjunction with accompanying drawing the utility model is further described:
The utility model sealing is by the obstruct of two base rings 1; middle employing semisolid stuffing box packing 2 sealing layerings (it includes multiple fiber or graphite); reach and form seamless composite ring; the irregular place of the axostylus axostyle 3 of its shape and Stuffing box casing and internal diameter coincide; eliminated the vacancy of Stuffing box; realized sealing fully; do not have any seepage approach; also no longer need wash away; and then water-saving and electricity-saving, this kind sealing in use can be clung the axostylus axostyle 3 of internal diameter or the filler tank wall of the axle sleeve and the diameter of axle, rotates the low friction zone rather than the relative axle sleeve that appear at semisolid stuffing box packing 2 and weares and teares; protect equipment, saved the expense of equipment replacement.
Claims (2)
1, a kind of pump seals with stratified shear, it is characterized in that being provided with two base rings (1) at the Stuffing box two ends, is filled with semisolid stuffing box packing (2) in two base rings (1) and axostylus axostyle (3) and Stuffing box.
2, pump according to claim 1 seals with stratified shear, it is characterized in that semisolid stuffing box packing (2) contains multiple fiber or graphite.
