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.

一般机械设备五金件用28碍贬窜去油蜡，光学镜片用40碍，实验室科研用100碍,尝颁顿半导体材料元件1惭贬窜及以上。现在一般厂家提供的超声波清洗机都能够调理输出功率，在考虑了整理规则和整理时刻的前提下，能够挑选适宜的输出功率。

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.

除蜡油一般采用偏碱性的清洗液，温度控制在75度上下适宜，如规则的工作效率和清洗质量等，有些溶剂能够提供挑选。超声波清洗机的超声频率越低，对液体形成空蚀越简单，效果也越好；频率高且超声专一性强，合适细微物体的清洗。

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.

超声功率越大，空化效果越强，整理速度越快，实际效果越好。而对于外表较光滑、精度较高的产物，采用长时刻高功率的清洗会对外表物体产生&濒诲辩耻辞;空蚀&谤诲辩耻辞;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.

挑选超声清洗，一般有两种类型的洗涤剂，分别为化学有机溶剂和水基洗涤剂。整理物质的氧化效果，再加上超声波整理的物理效果，两者的效果紧密结合，才干充沛、合理地对物体进行整理。一般来说，30℃-40℃的超音波侵蚀实际上效果很好。洗涤剂则是温度越高，效果越显着。通常详细运用超声波清洗时，运用温度为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 ℃.

柴油发电机组一般运行500h后应更换机油一次，但有时候未到更换期，或还没用多长时间出现机油变稀、杂质增多现象，无法继续使用。     柴油发电机组机油为何会变质过快     ①、机油牌号不对、质量达不到要求，一般增压和标定转速大于2000r/min的柴油发电机应选用CC级以上的机油；     ②、柴油机发电机技术状况不好，窜气、窜油、配合间隙过大或油温过高；     ③、柴油机发电机经常在低温、低负荷、低速下运转，活塞变形量不够，燃烧不完全，有柴油沿缸 壁进入油底壳使机油稀释变质；     ④、废气进入油底壳凝结成水分和酸性物质，使机油变质；     ⑤、机油滤芯脏，未经滤清的脏机油进入润滑部位，加速了零件的磨损。     ⑥、滤芯密封圈破裂而发生内漏，一部分机油未经滤芯而直接通过滤清器而造成机油变质。

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.
