金屬產品清洗機設備需要清洗多長時間？

作者：admin來源：http://www.dijiushangdian.cn/時間：2021-12-25

隨著技術的發展和環境保護要求的提高，在汽車及零部件生產過程中，零部件清洗工藝對清洗設備和清洗劑也提出了更高的要求。汽車金屬零部件清洗的一般要求如下：清洗速度快，在清洗機工藝設定的清洗時間內，可徹底除去金屬表面污物；對清洗機和被清洗零部件無腐蝕性；清洗劑成本低，環保、氣味溫和；清洗過程中，不在清洗對象表面殘留不溶物，不產生新污物，不形成新的有害于后續工序的覆蓋層，不影響產品質量。

With the development of technology and the improvement of environmental protection requirements, in the production process of automobile and parts, the parts cleaning process also puts forward higher requirements for cleaning equipment and cleaning agents. The general requirements for cleaning automobile metal parts are as follows: the cleaning speed is fast, and the dirt on the metal surface can be completely removed within the cleaning time set by the cleaning machine process; No corrosion to the cleaning machine and cleaned parts; The cleaning agent has the advantages of low cost, environmental protection and mild smell; During the cleaning process, no insoluble matter remains on the surface of the cleaning object, no new dirt is generated, no new covering layer harmful to subsequent processes is formed, and the product quality is not affected.

工程師推薦清洗劑時不僅要滿足工藝要求，還必須在清洗設備及清洗方式、清洗零部件材質、零件表面污垢類型以及下一道工序、水質和車間環境等眾多要素之間做到權衡。

When recommending cleaning agent, the Engineer shall not only meet the process requirements, but also make a trade-off between many factors such as cleaning equipment and cleaning method, cleaning part material, part surface dirt type, next process, water quality and workshop environment.

常用的清洗設備包括：浸入式清洗、噴淋清洗、高壓噴淋清洗以及超聲波清洗設備。

Common cleaning equipment includes immersion cleaning, spray cleaning, high-pressure spray cleaning and ultrasonic cleaning equipment.

浸入式清洗一般清洗的零部件為多腔體，要求清洗劑具有較強的清洗能力，對于清洗劑消泡性能要求不高，但要求清洗劑具有一定的乳化雜油的能力，這樣才能保障零部件在清洗并被取出清洗劑后不會被清洗掉的雜油二次污染其表面。乳化雜油能力強的清洗劑缺點是清洗劑清洗能力逐步降低，導致清洗劑使用壽命較短。

Generally, the parts to be cleaned by immersion cleaning are multi cavity, which requires the cleaning agent to have strong cleaning ability, and the defoaming performance of the cleaning agent is not high, but the cleaning agent is required to have a certain ability to emulsify miscellaneous oil, so as to ensure that the surface of the parts will not be polluted by the cleaned miscellaneous oil after the cleaning agent is taken out. The disadvantage of the cleaning agent with strong emulsified miscellaneous oil ability is that the cleaning ability of the cleaning agent is gradually reduced, resulting in short service life of the cleaning agent.

汽車變速器零部件的清洗大多采用通過式噴淋清洗機，一般分為清洗—漂洗—烘干三個過程，個別情況根據工藝要求而變化，清洗—清洗—漂洗—烘干或清洗—漂洗—漂洗—烘干。噴淋清洗機配有撇油器，采用抗雜油能力較強的清洗劑可以提高清洗劑的使用壽命。如清洗的變速器零部件材質一般為鍛鋼，零部件表面污物多為低粘度切削液，選用清洗劑時在考慮清洗能力的同時要考慮清洗劑的消泡能力，一般情況下，隨著清洗劑溫度的升高，其去污能力也隨之提高，但超過一定溫度后，去污能力反而下降，推薦清洗劑時要考慮一個適宜的溫度范圍。另一方面，由于漂洗清洗劑濃度一般較低，范圍在0.5%～1.5%，要求清洗劑具有較好的防銹能力。

The cleaning of automobile transmission parts mostly adopts the through spray cleaning machine, which is generally divided into three processes: cleaning rinsing drying. Individual conditions change according to the process requirements, cleaning cleaning rinsing drying or cleaning rinsing rinsing rinsing drying. The spray cleaning machine is equipped with an oil skimmer. The use of cleaning agent with strong anti impurity oil ability can improve the service life of the cleaning agent. For example, the cleaned transmission parts are generally made of forged steel, and the dirt on the surface of the parts is mostly low viscosity cutting fluid. When selecting the cleaning agent, the defoaming ability of the cleaning agent should be considered while considering the cleaning ability. Generally, the decontamination ability increases with the increase of the temperature of the cleaning agent, but the decontamination ability decreases after exceeding a certain temperature, An optimum temperature range should be considered when recommending cleaning agents. On the other hand, because the concentration of rinsing cleaning agent is generally low, ranging from 0.5% to 1.5%, the cleaning agent is required to have good anti rust ability.

高壓噴淋清洗機在去除零部件表面污物的同時還可去除金屬表面毛刺，零件多采用定位和定點噴淋方式，要求清洗劑在高壓下有很好的抵抗泡沫能力。

High pressure spray cleaning machine can remove metal surface burrs while removing the dirt on the surface of the components, and the parts are mostly positioned and fixed spray. The cleaning agent is required to resist foam at high pressure.

一些特定工藝條件下，推薦清洗劑時必須要考慮對后面工序的影響，如在某變速器軸、齒生產工藝流程中：磨齒—噴淋清洗（中間清洗）—拋丸—噴淋清洗（終洗），其中噴淋中間清洗過程要考慮，清洗劑清洗零件烘干后，零部件表面不能有粘性清洗劑殘留或覆蓋膜。。

Under some specific process conditions, the impact on subsequent processes must be considered when recommending cleaning agent, such as on a transmission shaft In the tooth production process: gear grinding - spray cleaning (intermediate cleaning) - shot blasting - spray cleaning (final cleaning), which shall be considered in the spray intermediate cleaning process. After the parts are cleaned with cleaning agent and dried, there shall be no viscous cleaning agent residue or covering film on the surface of the parts..

我們都知道，清洗劑主要是用于去除工件表面的切削液、磨灰以及金屬顆粒物等，并提供短期的防銹作用。一般清洗劑的防銹能力在濕度、溫度高的車間條件下，不足以保證工序間防銹，特別是在夏季車間濕度、溫度較高的情況下。

As we all know, cleaning agents are mainly used to remove cutting fluid, grinding ash and metal particles on the workpiece surface, and provide short-term rust prevention. The antirust ability of general cleaning agents is not enough to ensure the antirust between processes under the workshop conditions of high humidity and temperature, especially under the conditions of high humidity and temperature in the workshop in summer.
