Description
Technical field：
This utility model is related to a kind of solid insulating material compression creep test fixture structure.
Background technology：
Solid insulating material is widely used in nuclear power steam turbine generator, under operation state of generator, is typically subjected to heat
Stress and the effect of mechanical stress.In order to meet electromotor under various operating modes can safe operation, solid insulating material should have
Enough tolerance thermal stress and the ability of mechanical stress.Compression creep test is examination solid insulating material in constant pressure, perseverance
A kind of method of longtime running reliability under the conditions of constant temperature degree, and the order of accuarcy of compression creep test depends on test fixture
Structure, therefore, it is necessary to carry out the research work of the compression creep test fixture of solid insulating material.Traditional steam turbine generator
It is made up of pressing plate, screw bolt and nut with the structure of solid insulating material compression creep test fixture, this clamp structure pressure
Keep bad, be once only capable of completing the test of 1 sample, inefficiency and energy resource consumption height.Improve work efficiency, section advocating
About the energy reduce discharge today it is necessary to design is optimized to compression creep test fixture, with reach improve work efficiency,
Reduce the purpose of energy resource consumption.
Content of the invention：The purpose of this utility model be provide a kind of can improve testing efficiency, energy saving solid exhausted
Edge material compression creep test fixture structure.
Technical scheme is as follows：
Metal bolts (1) are screwed in the screw of downside metal plate (2), at downside metal plate (2) upper surface center
Position is sequentially placed solid insulating material sample (3) and metal partion (metp) (4), until sample quantities reach 3, intermetallic metal is put down
Plate (5) is pressed in after being enclosed within metal bolts (1) on solid insulating material sample (3), in the metal spiral shell on intermetallic metal flat board (5) top
Bolt (1) is upper to place metal spring (6), upside metal plate (7) is inserted in after metal bolts (1) and is pressed on metal spring (6), press
Torque requirement according to regulation tightens metal nuts (8), installation solid insulating material compression creep test fixture.
Technique effect：
Upside metal plate in solid insulating material compression creep test fixture structure, intermetallic metal flat board, downside gold
Belong to flat board, metal partion (metp), metal bolts and metal nuts all using high-strength stainless steel material manufacture, this material can keep certainly
The glacing flatness of body, can bear high temperature, high mechanical stress, compared with traditional metal material, be difficult to get rusty, high mechanical strength,
It is unlikely to deform；Metal spring adopts spring steel making, compared with the spring of common steel making, the spring purity of spring steel making
High, consistent internal structure, processing profile and accurate size, in apparent good order and condition after processing, its elastic limit, strength degree, bend
Strong ratio, relaxation resistance, fatigue behaviour, quenching degree, heat-resisting, low temperature resistant, antioxidation, corrosion-resistant etc. functional, expire well
Sufficient clamp structure requires.
Solid insulating material compression creep test fixture can increase fixture heat resistance using this structure and machinery is strong
Degree, improves testing efficiency, reduces energy resource consumption in test process, reaches compression creep and tests to fixture heat resistance, mechanical resistant
The requirement of performance.
Brief description：
Fig. 1 is clamp structure schematic diagram
Specific embodiment：
As shown in figure 1, a kind of solid insulating material compression creep test fixture, metal bolts 1 are screwed in downside metal and puts down
In plate 2, suitably adjusted during installation it is ensured that metal bolts 1 are vertical with downside metal plate 2；By length be 25mm, width be
25mm, thickness are that the solid insulating material sample 3 of 10mm is placed on the metal plate 2 of downside, are sequentially placed metal partion (metp) 4 and solid
Insulant sample 3, until the quantity of solid insulating material sample 3 reaches 3；Intermetallic metal flat board 5 is enclosed within metal bolts 1
It is pressed on solid insulating material sample 3 after upper, complete sample and install；Metal spring 6 is enclosed within metal bolts 1 and is pressed in centre
On metal plate 5, it is pressed in after upside metal plate 7 is enclosed within metal bolts 1 on metal spring 6, metal nuts 8 are screwed in gold
Belong on bolt 1, the torque requirement according to regulation tightens metal nuts 8, completes solid insulating material compression creep test fixture
Install.
