"HMV type hydrocarbon solvent vacuum cleaning machine" refers to a hydrocarbon solvent vacuum Cleaning machine, and "HMV type" may refer to a specific model or type of this equipment. The following is a detailed introduction about it:

Working principle

The principle of vacuum cleaning: Hydrocarbon cleaning agents usually contain a considerable amount of residual gas, with the gas content being 8 to 10 times that of water. Under normal pressure, when the high-frequency waves emitted by the ultrasonic vibrator encounter these gases, the cavitation effect will be significantly attenuated, affecting the cleaning effect. When vacuum cleaning is carried out, the cylinder drives the tank cover to automatically close the cleaning tank, and the vacuum degassing system starts to extract all the air in the tank. Under vacuum conditions, the gas in the narrow crevices of the products to be cleaned and the gas contained in the cleaning agent can be extracted. Then, the ultrasonic wave is activated, and the swinging device drives the washing basket to rotate, allowing the cleaning agent to thoroughly clean.

The principle of vacuum distillation recovery: It adopts an indirect heating method with heat transfer oil. The lower part of the tank is equipped with an external heating oil bag and an external heat transfer oil heating box. The cleaning agent to be recovered is pumped into the vacuum distillation recovery tank by a pump. Before entering, it undergoes heat exchange with the HC steam pipe for distillation recovery in the heat exchange cylinder. After vacuuming, the cleaning agent rapidly boils and evaporates to generate HC vapor, which is condensed and recovered in the condensation zone. The recovered pure cleaning agent is discharged into the storage tank for recycling.

Equipment composition

Ultrasonic system: By taking advantage of the cavitation effect of ultrasonic waves, the cleaning effect is enhanced. Electrical energy is converted into mechanical vibration energy, creating an ultrasonic sound field with alternating dense and sparse areas in the cleaning solution, generating a powerful shock wave to remove oil stains from the surface of the workpiece.

Vacuum degassing system: Before cleaning, the air in the cleaning tank is extracted to create a favorable vacuum environment for ultrasonic cleaning, reducing the attenuation effect of gas on ultrasonic waves. At the same time, the gas in the gaps of the workpieces and the cleaning agent is extracted.

Circulating filtration system: It filters the cleaning solution to remove impurities and dirt generated during the cleaning process, maintaining the cleanliness of the cleaning solution and extending its service life.

Robotic arm system: It is used to achieve automatic loading and unloading of workpieces and transfer between different cleaning tanks, improving the degree of automation and production efficiency of the cleaning process.

Vacuum drying system: After the cleaning is completed, by taking advantage of the principle that the boiling point of liquids decreases in a vacuum environment, the cleaning liquid on the surface of the workpiece rapidly boils and evaporates, achieving rapid drying and avoiding secondary contamination of the workpiece.

Vacuum distillation recovery system: By heating and vacuuming, the cleaning agent containing oil stains is evaporated, separating the cleaning agent from the oil stains. The pure cleaning agent after condensation can be recycled, achieving the purpose of cost savings and environmental protection.

HC concentration monitoring system: It can monitor the concentration of hydrocarbon cleaning agent in the cleaning tank in real time to ensure that the concentration of the cleaning agent is within an appropriate range and guarantee the cleaning effect.

Automatic fire extinguishing system: Due to the flammability of hydrocarbon cleaning agents, the automatic fire extinguishing system can be promptly activated in case of fire hazards to extinguish the flames and ensure the safety of equipment and personnel.

Electrical control system: It realizes the automatic control of the entire cleaning machine, including the start-up, stop, parameter setting and operation monitoring of each system, ensuring that the equipment operates in accordance with the set program and requirements.

Characteristics

Good cleaning effect: Comparable to or better than CFC-113, it can effectively remove various types of oil stains, grease, emulsions, cutting fluids and other dirt, and can thoroughly clean the dirt on the surface of parts, blind holes and narrow slits.

Strong compatibility: It has excellent compatibility with all the materials of the objects to be cleaned and will not cause corrosion, deformation or other damage to the workpieces being cleaned.

Stable performance: The hydrocarbon cleaning agent is stable in nature. It is not easy to decompose or deteriorate during the cleaning process, and there is no residue after cleaning, which will not have adverse effects on the subsequent processing or use of the workpiece.

It has obvious environmental protection advantages: it does not damage the ozone layer, is low-toxic, has a low global greenhouse effect, and meets environmental protection requirements.

High safety: Under vacuum conditions, the oxygen content is extremely low. Even if the temperature of the hydrocarbon cleaning agent reaches above the flash point, it will not burn due to the absence of oxygen. At the same time, it is equipped with safety devices such as an automatic fire extinguishing system, further enhancing the safety of use.

Application field

Automobile parts cleaning: such as car bearings, retainers, oil pump valve bodies, etc., can effectively remove residual grease, cutting fluid and other dirt during the processing.

Electronic component cleaning: Suitable for cleaning mobile phone casings, screens, electronic components, etc., it can remove oil stains and impurities on the surface, ensuring the performance and quality of electronic products.

Metal precision processing cleaning: For metal stamping parts, tools, molds and other metal products, it can remove oil stains, iron filings and other impurities on the surface, improving the surface finish and precision of the metal parts.

Watch parts cleaning: It can clean the precision components inside the watch, remove oil stains and dust, and ensure the timekeeping accuracy and service life of the watch.

Precious metal accessory cleaning: It can be used to clean gold and silver jewelry, jewels and other precious metal accessories, restoring their luster without causing damage to the precious metals.
