Abstract
The utility model provides a filling material seal gland of a centrifugal pump convenient to disassemble, belonging to a sealed filling material gland of a centrifugal pump normally used in the chemical industry. The seal gland comprises a main gland and an auxiliary gland, wherein the two ends of the main gland which is near to the inner side of a pump shaft are provided with a plurality of grooves; the two ends of the auxiliary gland which is near to the outer side of the pump shaft are provided with a plurality of lug bosses; and the main gland and the auxiliary gland are mutually matched with each other to be assembled into a whole body by means of socket joint through the grooves of the main gland and the lug bosses of the auxiliary gland. As the main gland and the auxiliary gland are mutually matched with each other to be assembled into a whole body by means of socket joint, the filling material seal gland preferably solves the problem when changing the filling material of the centrifugal pump, enlarges the work space, leads the change of the filling material of the centrifugal pump to be simple and convenient, and further improves the work efficiency. The filling material seal gland is simple in structure, and is particularly applied to the mini pump and the special pump.
Description
Technical field
The utility model relates to a kind of chemical industry centrifugal pump stuffing box packing gland commonly used, specifically a kind of easy-to-dismount centrifugal pump packing seal gland that can enlarge working space, be convenient to change filler.
Background technique
China's chemical enterprise delivering liquid material uses centrifugal pump mostly at present, particularly the gland sealed centrifugal pump.The packing seal technology is simple, practical, and at the bottom of the maintenance cost, using scope is extensive.But when changing filler a lot of inconveniences are arranged: 1, the gland of stuffing box packing is an integral body, can't take off from pump shaft, and working space is narrow and small, is not easy to clear up the old filler in the stuffing box.2, some has been done improved packing seal gland and has been made up of two semi-circular glands, is connected to form an integral body by bolt and compresses filler.But because of liquid that chemical enterprise is carried has corrosivity mostly, environment is abominable, and attachment bolt causes the dismounting difficulty easily by corrosion.3, also has a kind of more than half round packing seal gland, it is easy to disassemble from pump shaft, has enlarged the space on the surface, but only depends on more than half round gland itself can't compress filler, need on pump shaft, to install a whole pressure ring additional, to compress the effect that filler reaches sealing.But because of whole pressure ring is pressed in the stuffing box and can't takes out by more than half round gland, necessary disintegration pump head just can carry out filler and change, and program is numerous and diverse, influences the progress of work.And in disassembling the pump head process, decrease easily other parts of ring (as impeller etc.), cause the cost of overhaul to increase.
Summary of the invention
Goal of the invention of the present utility model is the little deficiency of dismounting difficulty, working space that exists at existing centrifugal pump Gland, provide a kind of simple in structure, enlarge working space, be convenient to change the easy-to-dismount centrifugal pump packing seal gland of filler.
Realize above-mentioned purpose by the following technical solutions: a kind of easy-to-dismount centrifugal pump packing seal gland, described sealing gland is divided into main gland and secondary gland, the two ends of described main gland have groove near the pump shaft inboard, secondary gland two ends are provided with boss near the pump shaft outside, and main gland and secondary gland are installed as one by the spigot and socket type assembly that cooperatively interacts of main gland groove and secondary gland boss.
Adopt technique scheme, compared with prior art, the spigot and socket type assembly is installed as one because the secondary gland of main pressure of the present utility model cooperatively interacts, the centrifugal pump that solves in the Chemical Manufacture preferably to be run into is changed the difficult problem in the filler process, enlarged working space, the centrifugal pump filler is changed become simple and easy to do, and then increase work efficiency.The utility model is simple in structure, is particularly useful for miniature pump and specific pump.

Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Present embodiment is a kind of easy-to-dismount centrifugal pump packing seal gland, is made up of a main gland 1 and a secondary gland 3, and the material of major and minor gland is a carbon steel.See accompanying drawing 1, Fig. 2 and Fig. 5 have groove 2 at main gland 1 two ends near the pump shaft side.See accompanying drawing 2～4, be processed into boss 4 at secondary gland 3 two ends near the pump shaft side, main gland 1 and secondary gland 3 are installed by the spigot and socket type assembly that cooperatively interacts of main gland groove 2 and secondary gland boss 4, form an integral body.
As preferred version, the internal diameter of main gland 1 of the present utility model and secondary gland 3 is slightly larger than the diameter≤1mm of pump shaft 5.
See Fig. 6, in order to prevent corrosion, 2 places are coated with butter to prevent corrosion at main gland groove.Only need during installation main gland 1 is pressed close to pump shaft 5 with secondary gland 3, the groove 2 of main gland 1 aligns with the boss 4 of secondary gland 3 to insert and gets final product, thereby forms the Gland of an integral body, puts into stuffing box 6, tightens the bolt that gland is connected with the pump housing.This main gland 1 is connected with boss 3 socket joints by groove 2 with secondary gland 3, need not use bolt to link to each other, and also need not use packing press ring.Only need unclamp the bolt that gland links to each other with the pump housing when changing filler 7, when pulling out main gland 1, secondary gland 3 is in company with taking out of, and separation automatically, can carry out the replacing of filler 7.
Claims (2)
1. easy-to-dismount centrifugal pump packing seal gland, it is characterized in that, described sealing gland is divided into main gland and secondary gland, the two ends of described main gland have groove, secondary gland two ends are provided with boss, and main gland and secondary gland are installed as one by the groove at main gland two ends and the boss spigot and socket type assembly at secondary gland two ends.
2. easy-to-dismount centrifugal pump packing seal gland according to claim 1 is characterized in that the internal diameter of described main gland and secondary gland is greater than centrifugal pump pump shaft diameter.
