避免超聲波清洗機(jī)清洗工件受損的方式方法

來源:http://www.paradisecovekirk.com/ 時(shí)間: 2022-12-12 瀏覽次數(shù): 0

運(yùn)用超聲波清洗機(jī),看一下你所清洗的產(chǎn)品,然后用什么洗劑來確認(rèn)你所用的超聲頻率。假設(shè)您的超聲波清洗機(jī)有幾個(gè)槽體,有加溫有吹干或慢拉這些,要考慮的因素較多,溫度、洗液濃度和清洗時(shí)刻等。
Use the ultrasonic cleaner to check the product you are cleaning, and then use what lotion to confirm the ultrasonic frequency you are using. Assume that your ultrasonic cleaner has several tanks, including heating, drying or slow pulling. There are many factors to consider, such as temperature, detergent concentration and cleaning time.
一般機(jī)械設(shè)備五金件用28KHZ去油蠟,光學(xué)鏡片用40K,實(shí)驗(yàn)室科研用100K,LCD半導(dǎo)體材料元件1MHZ及以上?,F(xiàn)在一般廠家提供的超聲波清洗機(jī)都能夠調(diào)理輸出功率,在考慮了整理規(guī)則和整理時(shí)刻的前提下,能夠挑選適宜的輸出功率。
28KHZ degreasing wax is used for hardware of general mechanical equipment, 40K for optical lens, 100K for laboratory scientific research, and 1MHZ or above for LCD semiconductor material elements. Now the ultrasonic cleaners provided by general manufacturers can adjust the output power, and can select the appropriate output power on the premise of considering the finishing rules and finishing time.
除蠟油一般采用偏堿性的清洗液,溫度控制在75度上下適宜,如規(guī)則的工作效率和清洗質(zhì)量等,有些溶劑能夠提供挑選。超聲波清洗機(jī)的超聲頻率越低,對液體形成空蝕越簡單,效果也越好;頻率高且超聲專一性強(qiáng),合適細(xì)微物體的清洗。
Generally, the wax remover uses alkaline cleaning solution, and the temperature should be controlled around 75 ℃, such as regular work efficiency and cleaning quality. Some solvents can be selected. The lower the ultrasonic frequency of the ultrasonic cleaner is, the simpler it is to form cavitation erosion on the liquid, and the better the effect is; High frequency and strong ultrasonic specificity, suitable for cleaning of fine objects.
超聲功率越大,空化效果越強(qiáng),整理速度越快,實(shí)際效果越好。而對于外表較光滑、精度較高的產(chǎn)品,采用長時(shí)刻高功率的清洗會對外表物體產(chǎn)生“空蝕”效果。
The higher the ultrasonic power, the stronger the cavitation effect, the faster the finishing speed, and the better the actual effect. For products with smooth appearance and high accuracy, long-term high-power cleaning will produce "cavitation" effect on external surface objects.
挑選超聲清洗,一般有兩種類型的洗滌劑,分別為化學(xué)有機(jī)溶劑和水基洗滌劑。整理物質(zhì)的氧化效果,再加上超聲波整理的物理效果,兩者的效果緊密結(jié)合,才干充沛、合理地對物體進(jìn)行整理。一般來說,30℃-40℃的超音波侵蝕實(shí)際上效果很好。洗滌劑則是溫度越高,效果越顯著。通常詳細(xì)運(yùn)用超聲波清洗時(shí),運(yùn)用溫度為40℃-60℃。
There are generally two types of detergents for ultrasonic cleaning, namely chemical organic solvent and water-based detergent. The oxidation effect of the finishing materials, coupled with the physical effect of ultrasonic finishing, are closely combined to finish the objects reasonably and efficiently. Generally speaking, ultrasonic erosion at 30 ℃ - 40 ℃ is actually very effective. The higher the temperature is, the more effective the detergent is. Generally, when ultrasonic cleaning is applied in detail, the application temperature is 40 ℃ - 60 ℃.
柴油發(fā)電機(jī)組一般運(yùn)行500h后應(yīng)更換機(jī)油一次,但有時(shí)候未到更換期,或還沒用多長時(shí)間就出現(xiàn)機(jī)油變稀、雜質(zhì)增多現(xiàn)象,無法繼續(xù)使用。     柴油發(fā)電機(jī)組機(jī)油為何會變質(zhì)過快     ①、機(jī)油牌號不對、質(zhì)量達(dá)不到要求,一般增壓和標(biāo)定轉(zhuǎn)速大于2000r/min的柴油發(fā)電機(jī)應(yīng)選用CC級以上的機(jī)油;     ②、柴油機(jī)發(fā)電機(jī)技術(shù)狀況不好,竄氣、竄油、配合間隙過大或油溫過高;     ③、柴油機(jī)發(fā)電機(jī)經(jīng)常在低溫、低負(fù)荷、低速下運(yùn)轉(zhuǎn),活塞變形量不夠,燃燒不完全,有柴油沿缸 壁進(jìn)入油底殼使機(jī)油稀釋變質(zhì);     ④、廢氣進(jìn)入油底殼凝結(jié)成水分和酸性物質(zhì),使機(jī)油變質(zhì);     ⑤、機(jī)油濾芯臟,未經(jīng)濾清的臟機(jī)油進(jìn)入潤滑部位,加速了零件的磨損。     ⑥、濾芯密封圈破裂而發(fā)生內(nèi)漏,一部分機(jī)油未經(jīng)濾芯而直接通過濾清器而造成機(jī)油變質(zhì)。
Generally, the engine oil of the diesel generator set should be replaced once after 500h of operation, but sometimes the replacement period is not reached, or the engine oil has become thinner and impurities have increased within a short period of time, which makes it impossible to continue to use. Why the engine oil of the diesel generator set deteriorates too fast ①. The engine oil is of the wrong brand and the quality does not meet the requirements. Generally, the diesel generator with supercharging and rated speed greater than 2000r/min should use the engine oil above CC level; ② The diesel generator is in poor technical condition, with gas and oil leakage, too large fitting clearance or too high oil temperature; ③ The diesel engine generator often operates at low temperature, low load and low speed. The piston deformation is not enough and the combustion is incomplete. Diesel enters the oil pan along the cylinder wall to dilute and deteriorate the oil; ④ Waste gas enters the oil pan and condenses into water and acid substances, which will deteriorate the engine oil; ⑤ The oil filter element is dirty, and the unfiltered dirty oil enters the lubricating part, which accelerates the wear of parts. ⑥ . The sealing ring of the filter element is broken and internal leakage occurs. Some engine oil directly passes through the filter element without passing through the filter element, causing deterioration of the engine oil.
