1)This equipment is mainly used to dismantle the electronic component from PCB of computer, TV set, and other electrical application facility. The PCB is heated to 200℃ to melt solder. The inner drum will spin out the solder and electronic component through 20mm*20mm screen from PCB board inside the drum. Then, the solder will be separated from the electronic component through vibrating screen 5mm*5mm. Solder recovery rate is 80%, and the purity is 60% as there is small pieces electronic component inside the solder. The recycled solder will be refined in an electrical resistance furnace to get the purity of 95%. 2)Compared with manual way, this dismantling equipment is automatical operation, high efficient, low cost, small covering area, easy operation, and no dust pollution. The PCB after dismantled, called base board, can be recycled by physical methods to get copper and other non-metal material. The dismantling rate can be to achieve 95%. 3)And its shell is double-layer and heat preservation.

　　O-rings are widely used in various industries for sealing purposes. They are circular rubber rings that are designed to fit into a groove and create a seal between two parts. O-rings come in different sizes, materials, and colors. While the size and material of an O-ring are crucial factors to consider, many people wonder if the color of an O-ring has any significance. In this article, we will explore this question and shed light on the importance of O-ring colors. 　　Firstly, it is important to note that the color of an O-ring does not have any direct impact on its functionality or performance. The primary purpose of an O-ring is to create a reliable seal, and this is determined by its size, material, and the design of the groove it fits into. The color of an O-ring is simply a visual characteristic and does not affect its sealing capabilities. 　　However, the color of an O-ring can be used as an indicator for specific applications or materials. In some industries, different colors are used to differentiate between O-rings made from different materials. For example, black O-rings are commonly made from nitrile rubber, which is known for its resistance to oil and fuel. On the other hand, red O-rings are often made from silicone rubber, which has excellent resistance to extreme temperatures. By using different colors, it becomes easier for technicians and engineers to identify the type of O-ring required for a particular application. 　　In addition, the color of an O-ring can also indicate its hardness or durometer. Durometer is a measure of the hardness of a material, and O-rings are available in different durometer ratings. For instance, blue O-rings are typically softer, while green O-rings are harder. By using different colors to represent different durometer ratings, it becomes simpler to select the appropriate O-ring for a specific sealing application. 　　Furthermore, the color of an O-ring can be used as a visual quality control indicator. During the manufacturing process, O-rings undergo various quality checks to ensure they meet the required standards. By assigning different colors to O-rings that have passed these quality checks, it becomes easier to identify and separate them from those that have not. This visual indicator helps in maintaining quality control and ensuring that only properly manufactured O-rings are used in critical applications. 　　While the color of an O-ring does not directly affect its functionality, it can serve as an indicator for specific applications, materials, hardness, and quality control. Different colors can be used to differentiate between O-rings made from different materials or with different durometer ratings. Additionally, assigning colors to indicate quality control helps in ensuring that only properly manufactured O-rings are used. Therefore, while the color of an O-ring may not have a significant impact, it does have some practical uses in certain industries.

1. Description The wiring of electrical components for the start and operation of refrigerant compressors is a typical task in the field of refrigeration. Safety aspects also play an important role. With SR 171 this knowledge and these skills can be acquired. All components are operated and tested with mains voltage to provide high relevance for practice. The electrical components for the start and operation of the refrigerant compressor are arranged clearly visible. The electrical connection of the individual components is made with cables via the lab jacks. The components are e.g. the capacitor and startup relay necessary to start the motor. The circuit diagram on the front panel enables the easy allocation of the individual components. The refrigeration circuit with compressor and receiver enables the checking of the pressure switches on the intake and delivery side of the compressor. The pressure is set via valves and the pressure switch tripped. Two manometers enable the monitoring of the pressure curve. If one of the pressure switches trips, the current supply to the compressor is interrupted. The wiring and checking of other typical components of the safety chain, e.g. circuit breaker and automatic fuse, is also carried out.
