本实用新型公开了一种渣浆泵填料压盖，其包括两个形状相同的半环压盖，二者拼接成环状填料压盖，所述环状填料压盖套装在渣浆泵的旋转轴上并压在旋转轴与渣浆泵的填料箱之间的填料上，在两个半环压盖的两端拼接处的外侧均设有与渣浆泵壳体上的固定螺栓相对应的缺口。本实用新型采用分体式结构，更换盘根时可以方便地从渣浆泵上拆卸下来，使更换盘根的操作空间增大，便于检修人员将盘根压入填料箱，从而有效降低了填料更换难度，缩短了渣浆泵的维修时间，提高了设备维修效率。此外，轴套严重磨损或填料压盖变形时，还可以更换新的填料压盖，既保证了渣浆泵的密封性，又可避免备件的浪费。
The utility model discloses a slurry pump packing gland, which comprises two half-ring glands with the same shape, the two are spliced into an annular packing gland, and the annular packing gland is sleeved on the rotation of the slurry pump. The shaft is pressed on the packing between the rotating shaft and the stuffing box of the slurry pump, and the outer sides of the splices of the two half-ring glands are provided with bolts corresponding to the fixing bolts on the slurry pump casing. gap. The utility model adopts a split structure, which can be easily disassembled from the slurry pump when replacing the packing, so that the operation space for replacing the packing is enlarged, and it is convenient for maintenance personnel to press the packing into the stuffing box, thereby effectively reducing the replacement of packing. Difficulty, shorten the maintenance time of the slurry pump, and improve the equipment maintenance efficiency. In addition, when the shaft sleeve is seriously worn or the packing gland is deformed, a new packing gland can be replaced, which not only ensures the sealing performance of the slurry pump, but also avoids the waste of spare parts.
Description
Technical Field
The utility model relates to a split type slurry pump gland that packs convenient to maintenance belongs to liquid pump technical field.
Background
The slurry pump has the advantages of corrosion resistance, difficult abrasion, low requirement on sucked water (water slag and small solid particles in the water), high efficiency, strong centrifugal force and the like, so the slurry pump is widely applied to metallurgical enterprises. As shown in figure 1, utilize packing to seal between sediment stuff pump casing and the rotation axis, because the rotation axis is long-time rotatory, the wearing and tearing of packing are more serious, consequently need often to change packing (packing), nevertheless because current sediment stuff pump gland all is integral structure, can not demolish from the sediment stuff pump, operating space is narrow and small when leading to changing thick packing, and the maintainer is difficult to impress the packing to increased maintenance duration, reduced maintenance efficiency. If the gland needs to be replaced, the slurry pump needs to be replaced, and the serious waste of spare parts is caused. In addition, if the shaft sleeve is worn, the thickness of the packing is increased so as to ensure the sealing performance of the slurry pump, but the sealing performance of the slurry pump cannot be ensured because the combination area of the old gland and the new packing is small and the pressure is unevenly pressed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a slurry pump gland to prior art's drawback to improve the maintenance efficiency of slurry pump.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a slurry pump gland, includes the same semi-ring gland of two shapes in the constitution, and the two splices into annular gland, annular gland suit is on the rotation axis of slurry pump and presses on the filler between the stuffing box of rotation axis and slurry pump, all is equipped with the breach corresponding with the fixing bolt on the slurry pump casing in the outside of the both ends concatenation department of two semi-ring glands.
The slurry pump packing gland further comprises two pin shafts, and two ends of the semi-ring gland are connected with two ends of another semi-ring gland through the two pin shafts respectively.
Above-mentioned slurry pump packing gland, the one end and the semi-ring gland fixed connection of two round pin axles, the pinhole transition fit on the other semi-ring gland of the other end and another semi-ring gland.
The utility model discloses a split type structure can conveniently be dismantled from the sediment stuff pump when changing the packing, makes the operation space increase of changing the packing, and the easy access personnel impresses the packing into the stuffing box to effectively reduced the packing and changed the degree of difficulty, shortened the maintenance duration of sediment stuff pump, improved equipment maintenance efficiency. In addition, when the shaft sleeve is seriously abraded or the packing gland deforms, a new packing gland can be replaced, the sealing performance of the slurry pump is guaranteed, and the waste of spare parts can be avoided.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
FIG. 1 is a schematic view of the installation of a packing gland of a slurry pump;
fig. 2 is a schematic structural diagram of the present invention;
FIG. 3 is a schematic structural view of the semi-ring gland;
fig. 4 is a left side view of fig. 3.
The reference numbers in the figures are as follows: 1. the semi-ring gland comprises 1-1 parts of a semi-ring gland body, 2 parts of a pin shaft, 3 parts of a notch, 4 parts of a rotating shaft, 5 parts of a packing gland body, 6 parts of packing, 7 parts of a packing box.
Detailed Description
The utility model provides a split type slurry pump gland, this gland can convenient, demolish fast, for changing the packing provides convenient condition, uses this gland can shorten repair time, saves spare part expense, can change alone when the gland warp, need not change the slurry pump, the material resources of using manpower sparingly. The contact area between the gland and the packing can be increased by replacing a new packing gland, so that the packing can be pressed in conveniently, and the sealing performance of the slurry pump is ensured. The utility model discloses simple structure does not require the high accuracy in the manufacturing process, can not increase how much extra manufacturing cost.
Referring to fig. 2 to 4, the present invention mainly includes two half-ring glands 1 and two pin shafts 2. And notches 3 are arranged at two ends of the semi-ring gland 1 and used for penetrating fixing bolts.
One end of each pin shaft 2 is fixed on one semi-ring gland 1, and the other end of each pin shaft is inserted into a pin hole 1-1 in the other semi-ring gland 1.
When the semi-ring gland bush is used, the two semi-ring glands 1 are spliced into the annular gland bush, the annular gland bush is sleeved on a rotating shaft of a slurry pump and pressed on a packing between the rotating shaft and a packing box, and notches on two sides of the gland bush are fixed on the packing box through nuts and bolts.
When changing the packing, loosen the nut from the bolt with the spanner, take out two semi-ring gland 1 and two round pin axles 2, take out old packing and put into new packing, will sell axle 2 and fix on a semi-ring gland 1, put this semi-ring gland 1 on the bolt earlier, splice another semi-ring gland 1 with this semi-ring gland 1 together again, fasten the nut to the bolt with the spanner on, fix novel gland.
When the packing gland deforms, the nut is loosened, the deformed gland is taken out, a new gland is replaced, and then the nut is screwed down.
