Abstract
A kind of metal bellows mechanical seal pick-up unit of the utility model, comprise axle sleeve, described axle sleeve is rotated with pump shaft by transmission ring; Also comprise the experiment stationary ring be arranged on stationary ring mount pad; Described axle sleeve is provided with the mounting groove for installing corrugated metal pipe components; Mounting groove edge is stepped.There is the pick-up unit of said structure, the diameter of axle according to metallic bellows divides into groups, be equipped with one group of general axle sleeve, stationary ring and transmission ring respectively, separately join a general experimental pump combination to install, actual applying working condition according to metallic bellows regulates inspection parameter, allows metallic bellows accept detection in real-world operation.This mode accurately can detect the performance of metal bellows mechanical seal, simultaneously because of the simple general-purpose of checkout equipment, also effectively reduces cost.
Description
Technical field
The utility model relates to a kind of pick-up unit for detecting metal bellows mechanical seal.
Background technology
Mechanical seal industry development industry is now more extensive, has occurred various types of mechanical seal in market, the mechanical seal of conventional springs formula, magnetic mechanical seal, rubber bellows mechanical seal and application also metal bellows mechanical seal widely.
Various types of mechanical seal also needs corresponding checkout equipment.
For metal bellows mechanical seal, corrugated tube adopts welding technology to be connected with metal installation base, easily produces some invisible pores and weld the problems such as imperfect in welding process.Corrugated tube operationally should play the effect of elastic compensating power simultaneously, also will play transmission and sealing function.Therefore whether corrugated tube processing is qualified seems particularly important.
Present detection mode mainly two kinds.One is that manual observation detects, and because the range of observation of people's naked eyes is limited, some small problems can not check out at all, and production marketing still exists a lot of problem after going out.But adopt expensive ultrasonic instrument etc. to detect, instrument Detection results is no doubt good, but this also substantially increases production cost, the price increase of metal bellows mechanical seal is result also in the middle of invisible, metal bellows mechanical seal can not be used widely, also not detect the practical effect of metal bellows mechanical seal simultaneously.
Utility model content
For the technical matters of above-mentioned existence, the utility model provides a kind of metal bellows mechanical seal pick-up unit, can seal running environment by analog mechanical, detect corrugated metal pipe components.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of metal bellows mechanical seal pick-up unit, comprises axle sleeve, and described axle sleeve is rotated with pump shaft by transmission ring; Also comprise the experiment stationary ring be arranged on stationary ring mount pad; Described axle sleeve is provided with the mounting groove for installing corrugated metal pipe components; Mounting groove edge is stepped.
Improve as one, described axle sleeve utilizes the installing ring at two ends to be fixed on pump shaft.Replacing for convenience detach, carries out the quick detection of multiple corrugated metal pipe components.
Improve as one, after described stationary ring mount pad, be provided with limited block.Prevent axial float.
Usefulness of the present utility model is: the pick-up unit with said structure, the diameter of axle according to metallic bellows divides into groups, be equipped with one group of general axle sleeve, stationary ring and transmission ring respectively, separately join a general experimental pump combination to install, actual applying working condition according to metallic bellows regulates inspection parameter, allows metallic bellows accept detection in real-world operation.This mode accurately can detect the performance of metal bellows mechanical seal, simultaneously because of the simple general-purpose of checkout equipment, also effectively reduces cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1 installing ring, 2 axle sleeves, 3 mount pads, 4 experiment stationary ring, 5 stationary ring mount pads, 6 limited blocks, 7 transmission rings, 8 corrugated tubes, 9 rotating rings, 10 mounting grooves.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, in the utility model, corrugated metal pipe components comprises mount pad 3, corrugated tube 8, rotating ring 9.The utility model comprises axle sleeve 2, and axle sleeve 2 utilizes the installing ring 1 at two ends to be fixed on pump shaft.Described axle sleeve 2 is rotated with pump shaft by transmission ring 7; Also comprise the experiment stationary ring 4 be arranged on stationary ring mount pad 5; Limited block 6 is provided with after stationary ring mount pad 5.Described axle sleeve 2 is provided with the mounting groove 10 for installing corrugated metal pipe components; Mounting groove 10 can install the corrugated metal pipe components of different size from the inside to the outside respectively, makes mounting groove 10 edge stepped.
During use, first according to metallic bellows real work requirement for height, regulate corresponding installation site by itself and axle sleeve 2, test stationary ring 4, stationary ring mount pad 5, transmission ring 7, limited block 6 and O-ring seals and be assembled into a whole set of mechanical seal.Again the mechanical seal assembled is installed on the pump housing.
After ready, according to the requirement of actual working condition of corrugated tube 8, regulate the inlet and outlet pressure, power etc. of pump, corrugated metal pipe components is dynamically operated under approximate actual applying working condition, by time long or temporary transient running, observe the sealing effectiveness of corrugated metal pipe components.The object detecting corrugated metal pipe components is arrived with this.
Experiment pump is different from specialty pump, and reserved loading mechanization sealing station is larger, guarantees to detect more metal bellows mechanical seal; Axle sleeve 2 endoporus coordinates with pump shaft, and cylindrical is designed to series of steps according to corrugated metal pipe components endoporus and working depth, and length direction does not arrange stop means, can adapt to the mechanical seal testing of different operating height; The design of experiment stationary ring 5 end face is wider, and to adapt to wider sealing surface testing, the design of supporting pick-up unit is simultaneously with reference to the installation dimension of conventional product, not only special as detecting, and also can sell as formal product, cost-saving further with this.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
