Description
Technical field
The present invention relates to the fluid rotary machines such as various centrifugal multistage pump multiple centrifugal pumps fields, in particular to centrifugal pump rotation axis seal skill
A kind of art, and in particular to installation method of end face seal.
Background technique
Mechanical end face seal, abbreviation mechanical seal or end face seal are one of most commonly used rotation axis moving seal patterns.
End face seal generally has a pair of or several pairs of sealing rings, one of them is fixed on casing and remain stationary, and another is fixed on axis
It above and therewith turns round, forms seal face.It can be seen that end face seal forms sealing by the seal face of Relative vertical rotary shaft
Secondary or friction is secondary.Under the effect of fluid pressure and compensating element, elastic force and the cooperation of auxiliary seal, seal face keeps patch
Merging and makees opposite sliding, the gap very little of two end faces keeps one layer of very thin lubricating liquid film, and thickness is usually 0.5~
2.0um, so that leakage rate is kept in allowed limits.Therefore, end face seal must assure that sealed end with when using in assembly
Face is perpendicular with rotary shaft.
Compared to soft packing seal pattern, end face seal have good airproof performance, high reliablity, stability is good, vibration resistance is strong,
Last a long time, wide adaptability the advantages that, while the end face seal of various design sizes and material preferably meets different works
The application demand in industry field.But because end face seal has the shortcomings that components are more, manufacture is complicated, installation and replacement are inconvenient, especially
To complicated special applications that are multi-stage sealed and possessing support system, accurate assembly and the use of end face seal are proposed higher
Requirement.
The accurate assembly of end face seal is to guarantee the necessary condition of end face seal high reliability, while also can guarantee fluid
The planned maintenance interval average time (MTBPM) of rotating machinery maximizes and operating cost minimumization.
Summary of the invention
It is an object of the invention to require for end face seal structure complexity and assembly precision etc., it is close to provide a kind of end face
The installation method of envelope ensure that the seal face of end face seal is vertical with rotary shaft by the accurate installation of stationary ring and rotating ring
Degree, improves the reliability and stability of end face seal.
To achieve the above object, the technical scheme adopted by the invention is as follows: a kind of peace of mining centrifugal multistage pump end face seal
Dress method, comprising the following steps:
Step 1: checking mining centrifugal multistage pump seal chamber, main shaft, axle sleeve and end face seal various components, removes
External contaminant and burr guarantee without sharp edges；
Step 2: according to mining centrifugal multistage pump design drawing, using slide calliper rule and depthometer measuring tool, according to fixed on main shaft
The position of position end face accurately determines the installation site of moving ring assembly, and the correctly standardized reference line on main shaft, by rotating ring group
Part is inserted in main shaft and is slowly moved near reference line, and appropriate three positioning screws for pre-tightening moving ring assembly end face guarantee dynamic
Ring assemblies can not be moved axially relative to main shaft and positioning screw is in malcompression state；
Step 3: use the distance between depthometer measuring tool measurement and positioning end face and rotating ring rubbing surface, if it is measured away from
From between design size, there are deviations, pass sequentially through the compression degree of three positioning screws of adjusting moving ring assembly end face to dynamic
The position of ring assemblies is finely adjusted；
Step 4: choosing on end face of shaft bush through axle center and orthogonal two straight lines, two straight lines respectively with sleeve end
Face outer circle is crossed to form four points, is successively measured using vernier caliper vertical between four points of end face of shaft bush and Rotation ring positioning circle
Distance passes through the fine tuning to three positioning screws according to the vertical range measured every time, it is ensured that four points of end face of shaft bush and rotating ring
After vertical range between locating ring is equal, three positioning screws are compressed, the purpose is to guarantee Rotation ring positioning circle end face and axle sleeve
In plumbness；
Step 5: stop pin is inserted into the corresponding hole of stationary seat, then a certain amount of lubricating oil is uniformly applied to stationary ring auxiliary O
On type sealing ring, stationary ring auxiliary O-ring seal is inserted in from stationary ring tail portion, and stationary ring auxiliary O-ring seal is avoided to be inserted in stationary ring tail
Be distorted when portion with it is shear-deformable；
Step 6: the stationary ring for being equipped with stationary ring auxiliary O-ring seal is uniformly pressed into stationary seat, and makes the anti-rotation at the stationary ring back side
Cotter way is aligned with the stop pin being packed into stationary seat；
Step 7: the stationary seat for being equipped with stationary ring and stationary ring auxiliary O-ring seal is inserted on main shaft, stationary ring rubbing surface and rotating ring
Abrasive end face is formed between rubbing surface, and sealing function is played in a manner of clearance seal.
A kind of installation method of mining centrifugal multistage pump end face seal of the invention has the beneficial effect that: mining multistage centrifugal
The end face seal of pump has the shortcomings that components are more, manufacture is complicated, installation and replacement are inconvenient, while end face seal is determined on main shaft
Position is close with the positional relationship of entire rotor-support-foundation system.Therefore during mining centrifugal multistage pump end face seal is installed, pass through
The invention can relative position to moving ring assembly and Rotation ring positioning circle and end face squareness be adjusted, guarantee end face seal
Assembly precision, while the reliability and stability of end face seal can be improved, reduce the operating cost of mining centrifugal multistage pump.
