Description
Technical field
The utility model relates to a kind of woven parts, relates in particular to a kind of pilot jet and manufacturing equipment thereof.
Background technology
Along with development of technology, the field shuttleless loom of weaving full substitution fly-shuttle loom.And in gripper shuttle loom, water jet looms, Rapier looms and the air-jet loom, the excellent again performance of air-jet loom becomes development in future trend.Domestic air-jet loom total amount has reached more than 100,000, and from calendar year 2001, annual newly-increased quantity maintains about 20,000.Air-jet loom is finished the wefting insertion process by air-flow, generally adopts the mode of main burner+pilot jet+special-shaped reed at present.Average every air-jet loom approximately need use the pilot jet about 30, and be approximately at present 3-5 the service life of import pilot jet, be approximately the service life of homemade pilot jet about 1 year, therefore pilot jet becomes one of topmost expendable part of air-jet loom, and how to improve a focus that also becomes current air-jet loom research field service life of pilot jet.
The pilot jet jet pipe is generally formed by the corrosion resistant plate punching stretch, improves the method in its service life at present and mainly takes surfaces nitrided or titanizing, and is domestic owing to consider that the cost problem generally adopts nitrogen treatment.Treated pilot jet generally can double and reach about 2 years service life.But because at present the speed of air-jet loom improves constantly, the scope of the yarn that uses more and more widely, thereby pilot jet is had higher requirement.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of wear-resisting pilot jet, has solved the defective that lack service life in the prior art.
Technical scheme
The utility model provides a kind of wear-resisting pilot jet, comprises jet pipe 1 and sleeve 2, and there is the siliceous DLC film of one deck on the surface.
Described film is attached to nozzle surface by vapour deposition.
The manufacturing equipment of described a kind of wear-resisting pilot jet, comprising: vacuum meter 1, target 2, substrate 3, sample stage 4, vacuum system 5, magnetic field 6 and resonance 7, substrate 3 are placed on the sample stage 4, by target 2 as the siliceous DLC film of sputter source preparation.
The preparation method of diamond-film-like mainly comprises physical vapour deposition (PVD) and chemical vapour deposition (CVD).Physical gas-phase deposite method comprises specifically: ion beam depositing method, sputtering sedimentation, magnetic filtering cathode arc deposition, pulsed laser deposition etc.; Chemical gaseous phase depositing process comprises: the direct sunshine chemical vapour deposition (CVD), chemical gaseous phase achievement, electron cyclotron resonance chemical vapor deposition etc. are penetrated in the direct current glow discharge chemical vapour deposition (CVD) frequently.
Diamond-film-like is a kind of amorphous substate structure of carbon, belongs to amorphous carbon, and the chemical bond in the film mainly is diamond key and graphite key.
Beneficial effect
The main performance of diamond-film-like comprises: high rigidity and high elastic modulus, and excellent abrasive and low-friction coefficient, high chemical inertness can prevent extraneous corrosion etc.Therefore can improve greatly its service life by coating diamond-like film on pilot jet stainless steel jet pipe, thus the use cost of reduction air-jet loom.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Below in conjunction with specific embodiment the utility model is further elaborated, with reference to accompanying drawing 2.
Film adopts two comprehensive ion implant systems of discharge cavity microwave, and this system comprises vacuumized part, vacuum reaction part, produces plasma part and test section.Select for use pilot jet stainless steel jet pipe as matrix 3 materials, methane and argon gas are as reaction source gas, and silicon target 2 prepares siliceous diamond-film-like as sputtering source.
At first in vacuum chamber 5, carry out sputter clean number minute with Ar ion pair pilot jet stainless steel jet pipe, bombardment by ion and sputter effect make disengagings such as the impurity, greasy dirt, oxide of its top layer absorption, simultaneously by bombardment to the surface, improve the stainless steel watch surface temperature, thereby help the combination of film and reduce in conjunction with stress.Pilot jet stainless steel jet pipe is placed on the sample stage 4 in the settling chamber, and the height of sample stage is transferred to the appropriate location, shuts vacuum chamber 5, open mechanical pump and take out in advance, when vacuum meter vacuum reaches 2～8Pa, open molecular pump, such two pumps carry out relay-type bleeds, and vacuum is pumped down to 3 * 10
-3Pa, feed argon gas then, add magnet exciting coil 6 electric currents, drive microwave source 7, when power reaches setting value behind microwave starting, at this moment plasma density reaches maximum, add the radio frequency back bias voltage and add cooling water at matrix 3, make the Ar ion under the effect of back bias voltage, quicken to substrate 3 motions, inelastic collision takes place on the surface of substrate 3 in the Ar ion, and the impurity that adsorbs on the substrate 3 is sputtered away.After contaminant removal is clean, can carry out sputter to substrate 3,, close microwave 7 sources and magnetic field sources 6 then so will turn off Ar gas in order to prevent the Ar ion.Just can carry out film preparation through the substrate 3 after the cleaning of Ar ion.
After pilot jet stainless steel jet pipe cleans, on substrate 3, add the radio frequency back bias voltage, improve the performance of depositing of thin film speed and film, but it should be noted that after closing all devices, just can take out after must waiting sample to cool down naturally with vacuum chamber, therefore otherwise film is easy to peel off, and it is longer to cause chemical vapour deposition (CVD) to prepare time of film.
