For porcelain or glass umbellate form, the equipment of bell-shaped insulator application RTV antifouling flush paint
Technical field
The present invention relates to coating dip coating technical field, especially for porcelain or glass umbellate form, the equipment of bell-shaped insulator application RTV antifouling flush paint, be mainly used in porcelain or glass umbellate form, the dip-coating of bell-shaped insulator.
Background technology
Porcelain or glass umbellate form, bell-shaped insulator is widely used in transformer station, is a kind of conventional outdoor insulator, and its application places determines it and needs good antifouling property.In order to avoid the generation of pollution flashover accident, the general many kinds of measures such as adjusting creep distance, water flushing, semi-conducting glaze layer insulator and spraying Hydrophobic Coatings that uses.But in the antifouling work of transformer station works, adjust the mode of climbing to be restricted, and more exchange device or the time-consuming cost of external insulation parts.Although water backwashing manner is effective, but safeguard the hardest.Therefore, in order to improve pottery or the glass insulator electric property under the conditions of dirt is wet, typically all use the mode at its surface spraying RTV antifouling flush paint at present, utilize the hydrophobicity of RTV antifouling flush paint and migration of hydrophobicity not to reduce to the pollution flashover voltage ensureing insulator.
On porcelain or glass umbellate form, bell-shaped insulator, the common method of application RTV antifouling flush paint has artificial brushing, artificial dip-coating and artificial air to spray three kinds of modes at present, but these three mode has weak point respectively.
Artificial painting way: in the past, only demand can use, durable, do not require to quality, to outward appearance etc., and the market demand be relatively small, this mode is relatively popular.But it is as the fast development in market, power industry is more and more higher to the requirement of the construction quality of coating RTV antifouling flush paint, and the manufacturer of insulator gets more and more in addition, competes the most more and more fierce, more and more higher to the prescription of product, the inferior position of artificial brushing insulator the most slowly highlights, and such as, coating uniformity is poor, presentation quality is poor, having a small amount of bubble inside coating, production efficiency is low, and human cost is more and more higher.
Artificial dip coating manner: coating ratio is more uniform, but the quality stability of product is the highest, is affected by human factors relatively big, substandard products easily occurs.And hand labor intensity is big, and the efficiency of dip-coating is the most relatively low, can not meet the market demand.
Artificial air's spraying method: this mode equally exists weak point.One, special due to umbrella, bell jar shape insulator structure, complex contour, especially for two, three layers or the umbrella insulator of more layers, umbrella circular groove seam is deep, easily occurs dead angle in spraying process;Two, spraying uneven, thickness is difficult to hold, and easily produces and is coated with gob extension, skinning, piles up and produce the mass defects such as bubble;Three, in spraying process, in order to reach certain coating layer thickness, need to be repeated the program of spraying, surface drying, it is impossible to disposably complete to spray, take time and effort, inefficiency;Four, in spraying process, the volatile solvent discharge in coating is higher, and at least over 50%, the pollution to environment is big, also big to the health threat of people, and manually brushes the volatile solvent discharge with artificial dip coating manner and be substantially all below 50%, the safest.
In sum, existing three kinds of construction methods all cannot meet efficiently, automatization's coating, the controllability of the gentle quality of high quality water, low environmental protection, high security.Therefore, necessary a kind of new equipment newly developed or technique complete the application of insulator, to improve product quality and production efficiency, and the requirement of environmental protection to be met.

Carrying out such scheme further preferably, also including PLC control cabinet, described deceleration frequency modulation motor is connected with PLC control cabinet by data wire.By PLC control cabinet, the work process of deceleration frequency modulation motor is automatically controlled, can accurately control insulator rotating speed of different phase in dip coating process, it is ensured that coating uniform, smooth in appearance.Owing to the rotating speed of the frequency modulation motor that slows down in dip coating process will control, at tens turns per minute, even only have several turns in the slowest stage, the volatile solvent volatile quantity in lotion is less than 50%, little on environmental and human health impacts impact.
Carrying out such scheme further preferably, also including a corner reductor and an angle electrical machinery, the input of described corner reductor is connected with the output shaft of described angle electrical machinery, and outfan is connected with described bearing block.By this preferred version, insulator angle in different phase is immersed in lotion can carry out accurate and stable control, thus avoid the generation of bubble in coating, dip-coating quality is guaranteed further.
Carrying out such scheme further preferably, described angle electrical machinery is connected with described PLC control cabinet by data wire.By PLC control cabinet, insulator angle in different phase is immersed in lotion being carried out Automated condtrol, reliability is higher.Further, after deceleration frequency modulation motor and angle electrical machinery all realize Automated condtrol, operator need not keep at the scene always, thus avoids the solvent flashing impact on health in dip coating process as few as possible.
Carrying out such scheme further preferably, described PLC control cabinet is also circumscribed with a control knob as switch.
Carrying out such scheme further preferably, described PLC control cabinet is arranged on the bottom of described mainframe, and described control knob is arranged on the side, top of described mainframe.
Above-mentioned two optimization technique means are primarily to make each device layout compacter, more convenient to operate.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows:
1, the umbellate form of the different size after dip-coating, bell-shaped pottery or glass insulator product surface quality is smooth, bubble-free, without drip hang, without pile up, thickness uniformity.
2, in dip coating process, the discharge capacity of VOC below 50%, Environmental Risk and the health effect of workmen is reduced.
