1、 Mechanical cleaning method of Ultrasonic cleaning:

（1）手工清洗法使用金属刷、刮刀等工具手工清洗零件和零件表面的污垢。该方法还包括用棉、丝织物、合成纤维制品和麂皮擦拭零件和零件表面以去除污垢。

(1) The manual cleaning method uses tools such as metal brushes and scrapers to manually clean parts and dirt on their surfaces. The method also includes wiping parts and parts surfaces with cotton, silk fabric, Synthetic fiber products and chamois to remove dirt.

（2）机械工具清洗法使用电动或风动工具驱动金属刷、软砂轮等。去除零件和零件表面的积碳、腐蚀和油漆层。

(2) The mechanical tool cleaning method uses electric or pneumatic tools to drive metal brushes, soft grinding wheels, etc. Remove carbon deposits, corrosion, and paint layers from the parts and their surfaces.

（3）压缩空气吹扫法用压缩空气吹扫复盖在零件表面的干燥灰尘、油泥等。

(3) The compressed air blowing method uses compressed air to blow away dry dust, oil sludge, etc. that cover the surface of the parts.

（4）高压水洗法。

(4) High pressure water washing method.

（5）磨料清洗法用压缩空气流或压力水流导向的软磨料和硬磨料撞击零件表面，破坏污垢层，带走残渣。主要用于去除积碳、腐蚀和油漆。

(5) The abrasive cleaning method uses compressed air flow or pressure water flow to guide soft and hard abrasives to impact the surface of the part, damaging the dirt layer and carrying away the residue. Mainly used to remove carbon deposits, corrosion, and paint.

二、浸泡，煮洗法

2、 Soaking and boiling method

浸渍和烹饪是一种相对原始的清洁方法。浸渍是将待清洗的零件和零件浸渍在清洗液外，依靠清洗液和污垢之间的物理化学反应，使污垢逐渐软化，亲松逐渐转变为逛离状态，从零件和零件表面脱落。浸渍清洗时间长，效率低。但它具有清洗设备简单、人工少等优点，因此得到了广泛的应用。

Soaking and cooking are relatively primitive cleaning methods. Impregnation is the process of immersing the parts and components to be cleaned outside the cleaning solution. By relying on the physical and chemical reaction between the cleaning solution and the dirt, the dirt gradually softens, becomes loose, and becomes detached from the surface of the parts and components. Long immersion cleaning time and low efficiency. But it has the advantages of simple cleaning equipment and less labor, so it has been widely used.

煮洗是将洗涤液加热到沸腾的洗涤方法。洗涤液在加热过程之外洗涤性能进一步提高。同时，油污和油脂也随着水果温度的升高而变软，或者溶解洗涤液被加热后，上下自然对流，污垢容易从被洗涤物上清洗。煮洗的效率高于浸洗。浸洗、煮洗使用的清洗设备主要有清洗槽和加热系统。

Boiling is a washing method of heating the washing solution to boiling point. The washing performance of the washing solution is further improved beyond the heating process. At the same time, the oil stain and grease also become soft with the rise of the fruit temperature, or after the dissolved detergent is heated, Natural convection flows up and down, and the dirt is easy to clean from the washed products. The efficiency of boiling is higher than that of soaking. The cleaning equipment used for soaking and boiling mainly includes cleaning tanks and heating systems.

三、压力冲洗方法

3、 Pressure flushing method

清洗液的冲击动能是影响压力清洗效果的主要因素。冲击动能越大，清洗效果越好。根据清洗压力的大小，压力清洗分为高压清洗、外压清洗和低压清洗三种。

The impact kinetic energy of cleaning fluid is the main factor affecting the effectiveness of pressure cleaning. The greater the impact kinetic energy, the better the cleaning effect. According to the size of cleaning pressure, pressure cleaning can be divided into three types: high-pressure cleaning, external pressure cleaning, and low-pressure cleaning.
