Abstract
The utility model discloses an output shaft leaking stoppage device of a centrifugal compressor. The output shaft leaking stoppage device is formed by a semi-circular upper cover plate and a semi-circular lower cover plate which are in axial symmetry in an opposite combination mode. An inner hole formed through opposite combination is in clearance fit with an output shaft. Bolt holes are evenly formed in the end faces of the upper cover plate and the lower cover plate in the circumferential direction. First oil seal grooves and second oil seal grooves are sequentially formed in the inwards-concave faces of the upper cover plate and the lower cover plate from the inside to the outside. The output shaft leaking stoppage device is reliable in sealing effect, corresponding adjustment can be carried out according to abrasion conditions of sealing padding in the using process, so that the requirement for long-time leaking stoppage is met, the structure is simple, operation is convenient, the output shaft leaking stoppage device can be produced in large volumes as a centrifugal compressor accessory, and popularization and application are facilitated.
Description
Technical field
The utility model relates to a kind of centrifugal compressed machine technology, relates in particular to a kind of centrifugal compressor output shaft leakage-baffling device.
Background technique
Centrifugal compressor output shaft oil leakage phenomenon is very general, is a great problem of pumping unit equipment control always.Due to the leakage of lubricant oil, need continuous supply lubricant oil to maintain equipment and run well, cause the lubricant oil waste very large.Simultaneously, can bring heavy cleaning to production after lubricant oil leaks, bring pollution to surrounding environment, leak when serious and even can cause speed reducer internal gear, bearing because of oil starvation, lubrication effect is poor and damage.At present, for pumping unit output shaft oil leakage phenomenon, on-the-spot solution commonly used has two kinds: 1, tear go back to machine maintenance department open and carry out the integral body maintenance, change the oil sealing of wearing and tearing, but it is too high to do like this cost, workload is huge; 2, with felt, leak is carried out to shutoff, its leak stopping effective date is short, and sealing effect is poor.
Summary of the invention
The problem existed for above-mentioned prior art, the utility model provides a kind of centrifugal compressor output shaft leakage-baffling device.
To achieve these goals, the technical solution adopted in the utility model is: a kind of centrifugal compressor output shaft leakage-baffling device, the semi-circular upper cover plate and the lower cover plate that comprise axial symmetry involute, and the endoporus that it involutes and output shaft are Spielpassung, the end face of upper cover plate and lower cover plate circumferentially is laid with bolt hole, and inner concave is provided with the first oil seal groove and the second oil seal groove from inside to outside successively.
As preferably, the junction of upper cover plate and lower cover plate is provided with sealing block.
Compared with prior art, the utility model has the advantage of: sealing effect is reliable, and can adjust accordingly according to the abrasion condition of stuffing box packing in using process, reach the requirement of long-time leak stopping, simple in structure, easy to operate, can be used as centrifugal compressor accessory batch process, easy to utilize.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 11, upper cover plate; 12, lower cover plate; 21, the first oil seal groove; 22, the second oil seal groove; 3, sealing block; 4, bolt hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As a kind of mode of execution of the present utility model, consult Fig. 1, the utility model comprises that the semi-circular upper cover plate 11 of axial symmetry and lower cover plate 12 involute, and the endoporus that it involutes and output shaft are Spielpassung, the end face of upper cover plate 11 and lower cover plate 12 circumferentially is laid with bolt hole 4, and inner concave is provided with the first oil seal groove 21 and the second oil seal groove 22 from inside to outside successively.Upper cover plate 11 is provided with sealing block 3 with the junction of lower cover plate 12.
The utility model sealing effect is reliable, and can adjust accordingly according to the abrasion condition of stuffing box packing in using process, reaches the requirement of long-time leak stopping, simple in structure, easy to operate, can be used as centrifugal compressor accessory batch process, easy to utilize.
Although in conjunction with current, be recognized as a most practical and preferred embodiment and described the utility model, but be to be understood that, the utility model is not limited to the disclosed embodiments, and is intended on the contrary contain multiple modification and equivalent arrangements included in the spirit and scope of the appended claims.
