Washing machine

A cleaning machine is a complete system that integrates key technologies such as pumps, valves, high-pressure water jetting, mechanical structures, material conveyance, and automation, along with auxiliary technologies including sealing, ventilation, heat exchange, cleaning‑fluid filtration, degreasing, and chip removal. It typically comprises several major subsystems: conveying, cleaning, filtration, drying, degreasing, slag removal, and electrical control.

Description of the Cleaning Machine’s Structural Components

❶ Transmission System

The conveyor system is a critical component of the cleaning machine, and its design quality directly impacts the overall performance of the equipment. The design of the cleaning machine’s conveyor system should meet technical requirements such as smooth operation, simple structure, resistance to component wear, accurate positioning, and convenient end‑side discharge. Conveyor systems can be implemented in various configurations, including step‑type, lift‑and‑step, plate‑chain, chain‑carriage, and motorized roller‑conveyor types; among these, the lift‑and‑step configuration further subdivides into pneumatic, hydraulic, and electric variants.

❷ Cleaning System

The cleaning system is responsible for the cleaning of components and constitutes the core of the entire cleaning machine. The distinctions among universal, specialized, flexible, ultrasonic, and other types of cleaning machines—based on differing principles—are primarily reflected in their cleaning systems. Cleaning systems encompass a wide array of processes; for instance, jet‑type cleaning systems, depending on the specific part and the varying cleaning requirements of different areas on the same part, may employ high‑pressure or low‑pressure jetting, as well as localized or position‑specific techniques such as insertion washing and blockage‑preventing washing.

❸ Filtration System

To enhance the cleanliness of parts and component assemblies, cleaning systems must be equipped with filters to ensure rigorous filtration of the cleaning fluid; accordingly, the filtration system plays a critical role in the cleaning machine. Depending on the filtration process and required precision, filters can be categorized into drum filters, belt‑type filters, bag filters, and advanced self‑cleaning filters.

❹ Drying System

After cleaning, components must pass through a drying system to remove residual moisture, preventing rust that could compromise assembly. Drying methods include air blow‑drying, thermal drying, and vacuum suction drying; air blow‑drying encompasses compressed‑air blow‑drying, cold‑air blow‑drying, and hot‑air blow‑drying. Vacuum suction drying is a more advanced technique and delivers the most effective moisture removal.

❺ Degreasing System

During the cleaning process, oil contaminants are washed off the parts and enter the cleaning fluid as impurities. If these contaminants are not promptly removed, the cleaning efficiency will be compromised; therefore, the degreasing system is an essential and integral component of the cleaning machine. Depending on their design and operating principles, equipment used in degreasing systems includes mesh-type degreasers, differential‑pressure degreasers, disc‑type degreasers, chain‑type degreasers, and others.

❻ Slag Removal System

The slag‑removal system is primarily responsible for collecting and treating impurities such as iron filings and molding sand contained in the filtrate. Its operation typically encompasses two key tasks: removing contaminants from the wastewater entering the sedimentation tank, and disposing of the solids captured by the filtration system. Ultimately, all collected impurities are conveyed to a sludge‑collection tank.

❼ Electrical Control System

The electrical control system is responsible for regulating the operating parameters of the cleaning machine, ensuring the coordinated, safe, reliable, and efficient operation of all major subsystems. Typically, the cleaning machine’s electrical control system employs a PLC (Programmable Logic Controller) as its primary controller, with proximity switches and pressure controllers serving as sensing elements to achieve…

Introduction to Types of Cleaning Machines 　　

A cleaning machine is used to flush out contaminants that are generated or introduced during the manufacturing, assembly, operation, and maintenance of hydraulic systems. It can also be employed for routine filtration of working fluids, enhancing cleanliness and helping to prevent or reduce failures caused by contamination, thereby ensuring high performance, reliability, and extended service life of hydraulic system equipment.

Classification of Cleaning Machines 　　

The range of cleaning machines includes: trichlorine cleaners, air‑blow cleaners, hydraulic cleaners, cold‑water high‑pressure cleaners, hot‑water high‑pressure cleaners, electric‑drive cleaners, gasoline‑drive cleaners, electric‑heated high‑pressure cleaners, diesel‑heated high‑pressure cleaners, ultra‑high‑pressure mobile cleaners, industrial stainless‑steel high‑pressure cleaners, explosion‑proof high‑pressure cleaners, hydraulic cleaners, ultrasonic cleaners, and gear‑box cleaning and maintenance machines.

◎ Hydraulic Cleaning Machine 　　

It is used to flush out contaminants generated or introduced during the manufacturing, assembly, operation, and maintenance of hydraulic systems; it can also be employed for routine filtration of working fluids, enhancing cleanliness and helping to prevent or reduce failures caused by contamination, thereby ensuring high performance, high reliability, and extended service life of hydraulic system equipment. The hydraulic cleaning unit achieves a cleanliness level of NAS 1638 Grade 2.

◎ High-pressure washer 　　

A high-pressure washer is a machine that uses a power unit—such as an electric motor, gasoline engine, or diesel engine—to drive a high-pressure plunger pump, generating pressurized water for cleaning surfaces. It effectively dislodges and rinses away dirt, achieving the desired surface‑cleaning result. Because it relies on a high‑pressure water jet to remove grime, high‑pressure cleaning is widely recognized as one of the most efficient, cost‑effective, and environmentally friendly cleaning methods worldwide. Depending on site conditions and process requirements, high‑pressure washers can be categorized into cold‑water, hot‑water, and gasoline‑engine models; in specialized applications, there are also explosion‑proof and food‑industry‑specific variants, among others.

◎ Ultrasonic cleaner 　　

It is a fully ultrasonic cleaning process that leverages the scientific and technological principle of ultrasonic cavitation. By means of vibration‑induced emission from an ultrasonic transducer, it thoroughly removes contaminants such as dirt, grease, and sediment adhering to objects, delivering a visibly effective cleaning result. This system integrates rinsing, cleaning, and sterilization into a single ultrasonic operation.

◎ Spray-type cleaning machine 　　

It is an industrial cleaning device that uses water pressure to rinse the surfaces of objects. It removes and washes away surface contaminants, thereby achieving thorough cleaning. Featuring multiple workstations, comprehensive functionality, a well‑designed structure, and user‑friendly operation, this machine delivers excellent cleaning results. For high‑volume parts processing, it significantly improves working conditions and enhances both cleaning and drying quality. The washer employs relay‑based fully automatic control; aside from manual loading and unloading of workpieces, all other process steps are performed automatically.

◎ Gearbox Cleaning and Maintenance Machine 　　

It provides a power source for gearbox cleaning, using negative high pressure to rapidly extract iron filings and other contaminants from within the gearbox along with the lubricating oil, followed by a positive‑pressure spray of filtered lubricant to flush the gearbox housing. The electrical control system and mobile support unit are integrated in a scientifically optimized layout, ensuring the gearbox cleaning and maintenance machine is highly maneuverable and adaptable to a wide range of working environments.
