Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby protection scope of the present invention is made more explicit defining so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that.
Referring to accompanying drawing 1, a kind of enclosed refrigeration compressor motor binding post, it comprises conductive copper bar 2, be sheathed on porcelain tube 1 on the conductive copper bar 2, be fixedly installed on the iron-clad 3 that fixes with external agency on porcelain tube 1 outer wall, the both ends of conductive copper bar 2 be exposed to respectively porcelain tube 1 the outside, both ends, and be electrically connected to the lead-out wire and the power supply of motor winding respectively.Be fixed together by the epoxy sealing pouring adhesive between conductive copper bar 2, porcelain tube 1, the iron-clad 3, riveting together after conductive copper bar 2, porcelain tube 1,3 of iron-clads applied the epoxy sealing pouring adhesive, cure in thermostatic drying chamber, stoving temperature is 100~110 ℃, and the time of curing is 6h; The outside of iron-clad 3 is formed with screw thread, and screw thread end is provided with the sealing ring that is " O " type; Packing ring and copper ring have been threaded on the conductive copper bar 2.
On Material Selection, the material of nut, packing ring material is H162; Conductive copper pole stock matter is T2; The conductive copper bar of conductor part should adopt the fine copper T among the GB5231 2Or T 3The material of insulator is 95 porcelain; The material of iron-clad is 45 #Carbon steel; The material of " O " type circle is a neoprene; Sealing is the HT epoxy pouring sealant with the material of glue.
Before producing, should at first carry out visual inspection to the outward appearance of each parts, thereby guarantee the superior electrical performance of final products: carry out chromatic passivation after electro-galvanized layer is arranged on the iron-clad, the coating color and luster should present uniform, bright colour; Sign should correct position on the insulator, writing is clear; " O " type circle not damaged, defective such as break, cleaning surfaces is smooth; All coppersmith spares (comprising packing ring, nut and conductive copper bar) are answered non-corroding.
Final products need be done the electric property that a series of test just can be guaranteed product.
1, withstand voltage test: iron-clad and conductive copper bar should be able to bear the power frequency withstand voltage test of 5000V/1min, do not puncture, damage or other anomaly.
2, mechanical performance: should be able to bear the torque test of 70Nm between iron-clad and the conductive copper bar and rotation between iron-clad and insulator, insulator and the conductive copper bar do not occur.
3, sealing property
Testing equipment and instrument: a, nitrogen pressure system: comprise high-pressure nitrogen bottle, gas pressure reduction system; B, be used for binding post special-purpose test frock is installed; C, charge the valve with emission gases, observe the air gauge of pressure; D, tank: the gas leakage situation that is used to observe binding post; E, other instrument and material: spanner, refrigerator oil.
Checkout procedure: in " O " of tested binding post type circle surface is coated with the Luo hole of the special-purpose test frock of last layer refrigerator oil → tested binding post is screwed in uniformly → pressure loading valve and the vent valves on the special-purpose test frock that screw the special-purpose test of binding post → connections frock and nitrogen pressure system → open respectively successively nitrogen cylinder with spanner inflate in testing frock → pressure in testing frock reaches 2.6MPa/mm 2In time, stops inflate → will to test frock in the frock to test and puts into tank (tested terminal is the 50mm place at least under water) → at tank pressurize 15min, and observe whether gas leakage is arranged → will test frock and take out → open venting valve on the test frock in the tank, the gas in the emission testing frock → binding post descend → is conscientiously wiped clean the moisture on the terminal from the test frock is imperial with spanner.
Consider the working condition of motor, temperature/experiments of sealing performance is set, mainly examine binding post when machine operation, the influence of temperature pair of wire connection terminals sealing property.Test method is: binding post is put into electrothermostat carefully, the baking oven thermostatic control is fixed on 70 ℃.Under this temperature, heat 8h.Naturally cool in case then after room temperature takes out, pair of wire connection terminals heats back sealing property inspection.
4, insulated porcelain sleeve bursting force test: insulated porcelain sleeve should be able to bear the test of 6.205MPa bursting force, and test is carried out on the test frock of special use.
5, anti-refrigerant performance
The check of performance before a, the test: should carry out withstand voltage test and experiments of sealing performance in cold-resistant matchmaker's performance test.
B, the test of anti-refrigerant performance:
The installation process of sample: binding post is kept upright in kettle → refuels and dry → seal → vacuumize → record cryogen → intensification and pressure adjustment.(note: in the time of should guaranteeing to add lubricating grease (oil), sample should have 2/3 part to be immersed in the refrigerator oil at least)
Dried: connect the power supply of heating system, after temperature in the kettle reaches 80 ℃, keep 1h, add refrigerator oil then.Add a cover and be cooled to room temperature behind the insulation 4h.
Charging of cold-producing medium: coat 704 fluid sealants uniformly on the sealing gasket of kettle and kettle cover, screw all holding screws after adding a cover, the evacuation tube with vacuum pump behind the dry 6h is connected on the external interface of autoclave; Start vacuum pump, the still internal pressure is evacuated to below the negative 0.1MPa; The cold-producing medium that adds regulation then; After several minutes the cold-producing medium in the still is discharged, in still, charge into cold-producing medium again.
The filling quantity of cold-producing medium: the about 1Kg of cold-producing medium, write down still internal pressure and ambient temperature, observe still internal pressure situation and ambient temperature behind the 24h.If no big variation can think that sealing meets the requirements.
Heat up and boost: during on-test, with oil bath kettle is heated earlier.When temperature rises, the situation that should observe temperature in the kettle and pressure at any time.When the temperature end reaches and pressure when rising to the operating pressure that surpasses regulation, should open the valve that charges of autoclave kettle cover, emit a part of refrigerant at leisure.According to said method the operating pressure of autoclave is adjusted to the experimental condition of stipulating below.
Test temperature: 76 ℃ of maximum operating temperatures+accelerated test temperature ≈; Test pressure: 1.03-2.42MPa (because of the cold-producing medium difference, pressure has together requirement, should according to circumstances pressure be adjusted in this scope); Test duration: 168h.
After test period finishes, by following condition cooling, release and the tested material of taking-up: cold-producing medium in the drain tap discharging still on the kettle cover of the power supply of closing test system → under the natural temperature condition, be cooled to room temperature → open → the open residue that kettle cover takes out tested material → tested material surface of cleaning.
Performance checking after cold-resistant matchmaker's test: should carry out withstand voltage test after test is finished, test voltage 2500V lasts 1min, carries out experiments of sealing performance again.
By above-mentioned execution mode, be not difficult to find out that the present invention is a kind of enclosed refrigeration compressor motor binding post that can steady in a long-term apply to low pressure refrigeration motor.Above execution mode only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the people that is familiar with this technology understand content of the present invention and is implemented; can not limit protection scope of the present invention with this, all equivalences that spirit is done according to the present invention change or modify all contains body in protection scope of the present invention.
