碳氢清洗机是一种以碳氢溶剂或改性醇溶剂为清洗介质，在全真空环境下运行的工业清洗设备。该设备利用超声波的空化效应增强清洗效果，通过真空状态降低溶剂沸点，实现出色渗透和污垢剥离。碳氢清洗技术是近年来在环保要求日益严格的背景下快速发展起来的清洗技术，具有经济成本、出色快速、节能环保和近乎零排放的特点，正逐步替代ODS及有害清洗溶剂。

A hydrocarbon cleaning machine is an industrial cleaning equipment that operates in a fully vacuum environment using hydrocarbon solvents or modified alcohol solvents as cleaning media. This device utilizes the cavitation effect of ultrasound to enhance the cleaning effect, reduces the boiling point of solvents through vacuum state, and achieves efficient penetration and dirt removal. Carbon hydrogen cleaning technology is a rapidly developing cleaning technology in recent years under the increasingly strict environmental requirements. It has the characteristics of economic cost, high efficiency and speed, energy conservation and environmental protection, and almost zero emissions. It is gradually replacing ODS and harmful cleaning solvents.

碳氢清洗机的工作原理建立在“相似相溶”的化学原则之上。碳氢清洗剂与大多数的润滑油、防锈油、机加工油同为非出色性的石油馏分，根据相似相溶原理，碳氢清洗剂清洗矿物油的效果优于卤代烃和水基清洗剂。在全自动真空碳氢清洗机中，设备生产主线通常由2个真空脱气超声波清洗槽、1个强力真空超声波清洗槽、2个蒸汽洗加真空干燥段组成。其工作原理是利用超声波渗透力强的机械震动力冲击工件表面，并结合碳氢清洗剂的化学去污作用，在真空状态下进行多维度清洗，使工件表面和盲孔、狭缝达到洁净标准。清洗和干燥通常在一个腔体内真空条件下完成。在真空条件下加热溶剂温度能提高溶剂的去污效果；在真空条件下干燥能降低溶剂的沸点，实现快速干燥。

The working principle of the hydrocarbon cleaning machine is based on the chemical principle of "similar solubility". Carbon hydrogen cleaning agents, along with most lubricating oils, rust proof oils, and machining oils, are non-polar petroleum fractions. According to the principle of similar solubility, carbon hydrogen cleaning agents are more effective in cleaning mineral oils than halogenated hydrocarbons and water-based cleaning agents. In a fully automatic vacuum hydrocarbon cleaning machine, the main production line usually consists of 2 vacuum degassing ultrasonic cleaning tanks, 1 strong vacuum ultrasonic cleaning tank, and 2 steam washing and vacuum drying sections. Its working principle is to use the strong mechanical vibration force of ultrasonic penetration to impact the surface of the workpiece, and combine it with the chemical cleaning effect of hydrocarbon cleaning agents to perform comprehensive cleaning under vacuum, so that the surface of the workpiece and blind holes and narrow slits meet the cleanliness standard. Cleaning and drying are usually carried out under vacuum conditions within a chamber. Heating the solvent temperature under vacuum conditions can improve the cleaning effect of the solvent; Drying under vacuum conditions can lower the boiling point of the solvent and achieve rapid drying.

碳氢清洗机的核心构成包括超声波系统、真空脱气系统、循环过滤系统、机械臂系统、真空干燥系统、真空蒸馏回收系统、碳氢浓度监测系统、自动灭火系统及电气控制系统等。清洗剂中残存的气体较多，含气量是水的8-10倍，超声波振动子发出的高周波遇到气体就会衰减，影响超声波的精密清洗效果，因此需要真空脱气系统先将槽内空气抽尽。设备采用PLC自动控制，清洗工艺通常包括真空喷淋清洗、真空超声波清洗、蒸汽清洗和真空干燥等多道工序。设备还配备蒸馏回收系统，实现碳氢清洗液的循环利用。

The core components of a hydrocarbon cleaning machine include an ultrasonic system, a vacuum degassing system, a circulating filtration system, a robotic arm system, a vacuum drying system, a vacuum distillation recovery system, a hydrocarbon concentration monitoring system, an automatic fire extinguishing system, and an electrical control system. There is a lot of residual gas in the cleaning agent, with a gas content 8-10 times that of water. The high-frequency waves emitted by the ultrasonic oscillator will attenuate when encountering gas, affecting the precision cleaning effect of the ultrasonic waves. Therefore, a vacuum degassing system is needed to first exhaust the air in the tank. The equipment adopts PLC automatic control, and the cleaning process usually includes multiple processes such as vacuum spray cleaning, vacuum ultrasonic cleaning, steam cleaning, and vacuum drying. The equipment is also equipped with a distillation recovery system to achieve the recycling of hydrocarbon cleaning solution.

在安全设计方面，由于碳氢清洗剂具有易燃特性，闪点在50℃-75℃之间，碳氢清洗机配备了防爆电器和自动灭火装置等安全设计。设备具有清洗效果好（与CFC-113相当或更好）、与所有清洗物材质有很好的相容性、性能稳定无残留物、不破坏臭氧层、低毒、全球温室效应低等一系列优良特性。

In terms of safety design, due to the flammable nature of hydrocarbon cleaning agents with flash points between 50 ℃ and 75 ℃, the hydrocarbon cleaning machine is equipped with explosion-proof electrical appliances and automatic fire extinguishing devices for safety design. The equipment has a series of excellent characteristics such as good cleaning effect (equivalent or better than CFCs 13), good compatibility with all cleaning materials, stable performance without residue, no damage to the ozone layer, low toxicity, and low global greenhouse effect.

碳氢清洗机主要应用于精密零件、电子元件、机械组件等工业零件的清洗。其核心应用场景包括汽车零部件、手机零部件、贵金属配饰、半导体及精密五金等领域的油脂、切削液等污染物清洗。非常适用于金属件脱脂、盲孔及狭缝清洁等要求较高的清洗任务。设备可提供单工位、多工位机型以满足不同生产规模的清洗需求。随着环保法规的日益严格和碳氢清洗技术的不断成熟，碳氢清洗机在热处理生产线、精密加工等领域得到了成功运用。

Carbon hydrogen cleaning machines are mainly used for cleaning industrial parts such as precision parts, electronic components, and mechanical components. Its core application scenarios include cleaning of pollutants such as grease and cutting fluids in the fields of automotive parts, mobile phone parts, precious metal accessories, semiconductors, and precision hardware. Specially suitable for cleaning tasks with high requirements such as degreasing of metal parts, cleaning of blind holes and narrow slits. The equipment can provide single station and multi station models to meet the cleaning needs of different production scales. With the increasingly strict environmental regulations and the continuous maturity of hydrocarbon cleaning technology, hydrocarbon cleaning machines have been successfully applied in fields such as heat treatment production lines and precision machining.
