A padding shaft sleeve is mounted on a pump shaft; a shield sleeve is mounted on the right pump shaft of the padding shaft sleeve; a pressure limiting sleeve is mounted on the outer wall of the padding shaft sleeve; a first-grade padding is arranged at the left side of the pressure limiting sleeve; a water seal ring is mounted at the left side of the first-grade padding; a second-grade padding is arranged at the left side of the water seal ring; the lower end of a padding gland bush is convexly arranged at the left side of the second-grade padding; a padding box body is mounted above the pressure limiting sleeve, the first-grade padding, the second-grade padding and the lower end salient of the padding gland bush; and the upper end of the padding gland bush is connected with the upper end of the padding box body through a bolt. The novel mineral draining pump pressure limiting sleeve mechanism has a simple structure and practical functions and has the advantages of long service life, high reliability as well as safety and practicability.
Description
Technical field
The utility model relates to the draining pump field, and mechanism is overlapped in particularly a kind of novel draining pump pressure limiting that is suitable for using in the mine.
Background technique
The draining pump that uses in the colliery problem that filler is installed tension occurs through regular meeting; at pump operation soon the filler failure phenomenon will appear; pump must be shut down the replacing filler, thereby brings harm for the safe operation of colliery drainage system, makes the service cycle of pump shorten.
Causing the underlying cause of this phenomenon mainly is that the workman is excessive in order to prevent that filler from leaking, and too is equipped with tight Gland, causes the seal cage dislocation between filler, seal cage lost efficacy, sparge water can't enter, and packing seal does not have sparge water, will soon lose efficacy when pump operation.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned not enough problem, provides a kind of new type mining draining pump pressure limiting to overlap mechanism, and is simple in structure, long service life, and the reliability height, practical.
The technical solution adopted in the utility model is: mechanism is overlapped in a kind of mining draining pump pressure limiting, comprise Gland, the filler casing, the pressure limiting cover, packing sleeve, sheath, first order filler, second level filler, seal cage and pump shaft, packing sleeve is installed on the pump shaft, sheath is installed on the pump shaft of packing sleeve right side, the pressure limiting cover is installed on the packing sleeve outer wall, first order filler places pressure limiting cover left side, seal cage is installed on first order filler left side, second level filler places the seal cage left side, Gland lower end projection places filler left side, the second level, the filler casing is installed on the pressure limiting cover, first order filler, on second level filler and the Gland lower end projection, the Gland upper end is connected by bolt with filler casing upper end.
Ring has maze trough in the described pressure limiting cover, is that zero allowance cooperates with packing sleeve, with the packing sleeve rotation, with the filler casing be tolerance fit, be pressed on the most inboard of filler casing by first order filler, no axial displacement on the left of it.
Described seal cage is installed between first order filler and the second level filler, forms swing offset with packing sleeve.
The utility model is simple in structure, compared with prior art has following characteristics and advantage:
Even 1, the Gland back of the body is dead, can be because of the compression of filler, the seal cage dislocation guarantees that forever filler has sparge water, can not lose efficacy.Improved the working life of filler greatly, shortened the replacement cycle of filler, quadruple working life.
2, increase the pressure limiting cover, filler can not push tension, the axle sleeve that can not wear and tear, and the internal consumption of pump does not increase, and can not cause efficient to lower, and is therefore more outstanding on energy-saving effect.
The draining pump rate of fault of the utility model structure is low, safeguards simply, and is safe and reliable to operation, and the workman is freed from the environment of spiritual high concentration, reduces labor intensity, improves personal safety.Increase the drainage system water displacement, improved the whole displacement volume of system, guaranteed draining safety effectively.When water leak accident takes place, time is life, the raising of drainage efficiency can significantly reduce casualties to alleviating and avoiding the generation of disaster to play a key effect, and can be widely used in the mine pump of conveying of the single-phase or heterogeneous fluid in fields, mine such as colliery, iron ore, gold mine.
To sum up, the utility model can provide a kind of simple in structure, the function model utility is mining draining pump pressure limiting cover mechanism, has long service life, reliability height, safe and practical advantage.
Description of drawings
Accompanying drawing 1 is that the schematic representation of mechanism is overlapped in a kind of mining draining pump pressure limiting.
Among the figure: 1 Gland, 2 filler casings, 3 pressure limiting covers, 4 packing sleeves, 5 sheaths, 6 first order fillers, 7 seal cages, 8 pump shafts, 9 second level fillers.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing, but the utility model is not limited to specific embodiment.
As shown in Figure 1, mechanism is overlapped in a kind of mining draining pump pressure limiting of the utility model, comprises Gland 1, filler casing 2, pressure limiting cover 3, packing sleeve 4, sheath 5, first order filler 6, second level filler 9, seal cage 7 and pump shaft 8.
Packing sleeve is installed on the pump shaft, sheath is installed on the pump shaft of packing sleeve right side, the pressure limiting cover is installed on the packing sleeve outer wall, first order filler places pressure limiting cover left side, seal cage is installed on first order filler left side, second level filler places the seal cage left side, Gland lower end projection places filler left side, the second level, the filler casing is installed on pressure limiting cover, first order filler, second level filler and the Gland lower end projection, and the Gland upper end is connected by bolt with filler casing upper end.
Ring has maze trough in the pressure limiting cover, is that zero allowance cooperates with packing sleeve, with the packing sleeve rotation, with the filler casing be tolerance fit, be pressed on the most inboard of filler casing by first order filler, no axial displacement on the left of it.
Seal cage is installed between first order filler and the second level filler, forms swing offset with packing sleeve.
Draining pump should be installed to the pressure limiting cover below the filler casing before first order filler is installed earlier, first order filler is installed again, then seal cage is installed to first order filler back, second level filler is installed again, be equipped with Gland and filler casing tight with bolt, the inboard nature of Gland can compress second level filler, seal cage, pressure limiting cover and first order filler, pump is when operation, packing sleeve can rotate with rotor part, and the first order and second level filler, seal cage, the pressure limiting cover can not rotate with axle sleeve, play good shaft sealing effect, could guarantee new type mining draining pump reliable operation, improved the whole efficiency and the life-span of pump.
