Little, easy to operate by the sealing detection fixture volume of electromotor I fulcrum, solve electromotor I
The problem of the fulcrum sealing propertytest when single-piece.The application of the sealing detection fixture of electromotor I fulcrum,
Operator is made quickly, accurately, the most individually to complete the sealing propertytest test of each fulcrum.At present, send out
The sealing detection fixture of motivation I fulcrum has been used for the test of tens electromotor densification device sealing propertytests,
, when bench test drive, all there is not altering the phenomenon of oil in the electromotor after densification device assembling after pass the test.
It addition, the fulcrum densification device after all sealing detection fixture overhaulings employing electromotor I fulcrum
Electromotor when other factory uses, do not find to alter oil phenomenon, the longest working time after these engine overhauls yet
More than 300 hours；As can be seen here, the application of the sealing detection fixture of electromotor I fulcrum carries greatly
The high reliability of electromotor.
Economic and Efficiency Analysis
The sealing detection clamp member of electromotor I fulcrum is few, simple in construction, and the material of use is common
45# steel and oil resistant rubber, the sealing detection fixture making electromotor I fulcrum is easy to process, and cost is relatively low.
Its mid-early stage investigation design cost 60,000 yuan, processing and manufacturing expense 20,000 yuan, equipment acceptance testing expenses 20,000
Unit, altogether cost price 100,000 yuan.
Service condition statistics according to other factory's RD-93 electromotor, evaluates every electromotor each fulcrum assembling,
Repair or change, test cost converts into RMB 80,000 yuan.Add each cost of labor, through statistics,
Every electromotor can save maintenance cost 300,000 yuans.
Further, since the application of the sealing detection fixture of electromotor I fulcrum, electromotor can be reduced and returning factory
Cycle during repairing, and substantial amounts of saved repair cost.Therefore, according to being on active service in Pakistan at present
50 electromotors calculate, this frock can be cost-effective 20,000,000 yuans of company, brings for company
Great economic benefit.
At present, 5 fulcrums of certain h type engine h domestic are consistent with RD-93 electromotor, the side of its dot encapsulation
Formula is the most identical.Therefore, the sealing detection fixture of electromotor I fulcrum extends on the electromotor of this model,
Improve the reliability of this electromotor, bring bigger economic benefit and social benefit for enterprise simultaneously.
According to above-described embodiment, the present invention just can be realized well.What deserves to be explained is, based on said structure
On the premise of design, for solving same technical problem, even if some made in the present invention are without substantive
Change or polishing, the essence of the technical scheme used still as the present invention, therefore its should also be as this
In the protection domain of invention.
