Description
Technical field
A kind of electric control gear for HVAF system of the utility model, and in particular to one kind meets supersonic speed
The electric control gear of flame-spraying system.
Background technology
In field of coal mining, as the nucleus equipment of fully mechanized coal face, hydraulic support reliably and efficiently can be supported and controlled
The top plate of working face, isolate goaf, prevent spoil from entering stope and promote conveyer.In working face complete set of equipments
In, the input of hydraulic support account for about 60% equipment cost.Column is the main load bearing component of hydraulic support, bears top plate work
For hydraulic support load and be delivered to base, and be chronically in the particular surroundings of underground mining.In severe work
Under environment, leg surface generally occurs within serious corrosion and wear phenomenon, and causes to reveal.So that bracket upright post is in roof pressure
Larger lower contracting amount is produced so as to cause hydraulic support to fail in the case of less, and induces roof accident, is seriously threatened
Safety of Coal Mine Production.According to correlation statistical analysis, coal mining accident, which has sizeable proportion, to be triggered because hydraulic support fails.Therefore it is complete
Face lifting the wear-resisting, anti-corrosion of leg surface, shock resistance, extend column service life and have great importance.
At present, the cylinder body of Homemade Hydraulic Supports column and stud materials are respectively 42CrMo steel, 27SiMn steel.Hydraulic support
The working environment of column is complicated severe.Be generally in it is a kind of moist, rich in SO2, H2S, CO2 and a large amount of dust in the environment of.
The steel such as 27SiMn steel are difficult to resist above-mentioned severe dust abrasion and anticorrosion work environment, it is thus typically necessary in column table
Face prepares protective coating column and protected, so as to improve the service life of column and hydraulic support.Meanwhile to surface be present
The column of damage carries out reparation and remanufactures and improve its performance and service life, and for Reducing Cost in Enterprises, economizing on resources has
Significance.At present, the most widely used leg surface manufacture and recovery technique are plating hard chrome protective layer.Although plating is hard
Chrome coating can meet the job requirement of column at present, but the problem of a large amount of urgent need to resolve be present.
First, caused Cr6+ can cause serious problem of environmental pollution during electroplating hard chrome.Chromium is torpescence in itself
Element, articles for daily use and joint prosthesis etc. can be can be safely used for, but chrome-plated process uses chromic acid solution, in chromium plating
Cheng Zhonghui produces substantial amounts of hydrogen, and bubble hydrogen can spray into chromic acid solution in air in rupture, produces acid mist, contains in acid mist
Carcinogenic Cr6+；Moreover, chrome-plating process can also produce substantial amounts of toxic waste and the waste water containing Cr6+.Therefore, countries in the world
Control to chrome-plated process is more and more stricter.Continuous lifting based on environmental requirement, for electroplating hard chrome, due to existing seriously
Pollution of hexa covalent chromium ion and face the state that must be eliminated.In addition, plating hard chrome coating itself equally exists great number of issues.Electricity
Hard chrome plating coating hardness is relatively relatively low（HV0.3800~900）, its wearability can not show a candle to some ceramics or cermet materials, this
Outside, electroplating technology needs strict control, when improper process control, micro-crack be present inside chromium coating, cause corrosive medium from
Surface penetration is to interface and etched the matrix, so that the corrosion resistance of coating declines.Moreover, electroplating technology sedimentation rate compared with
Slowly, the use compared with thickness coating is not suitable for.Therefore, based on above-mentioned great number of issues, need badly at present develop new column protective coating and
Recovery technique is so as to replacing electroplating hard chrome technology.
HVAF technology is a fast-developing in recent years thermally sprayed coating technology of preparing, in recent years a large amount of
Research shows, after being optimized to techniques such as spraying layer material, spraying coating process, coating performances, prepare in hydraulic prop and
Field is remanufactured, HVAF can substitute traditional plating hard chrome completely.
