The recycling of the whole plant and the application of enterprise equipment have also brought corresponding benefits to enterprises:
1. Automatic machines are convenient to manage; 2. Save the production cost of enterprises; 3. Improve the corporate image and enterprise; 4. It can liberate human work in dangerous areas and reduce the harm to human beings. For the recycling of second-hand equipment, we must organize it, set up a second-hand recycling company and make a good plan. This step is very important for future development. When recycling second-hand equipment, most of the second-hand equipment can only be dismantled as metal scrap. If it is recycled according to the equipment price, it can be at a loss even if it is cheaper, and most of it is treated at a slightly higher price than the scrap metal. For some scarce second-hand equipment, we can consider recycling it at a slightly higher price.
Zengcheng Milk Powder Factory Equipment Recycling Integrity Recycling Company: The circuit B uses a 2N3906 transistor, PNP type, and the buzzer LS2 is also connected to the collector of the transistor, and the driving signal is 5VTTL level. Because other parameters of 2N3906 are basically the same as those of 2N3904, the calculation process will not be described in detail. Both the above circuit diagrams can work normally. Compared with Figure 1, the two circuits connect the buzzer to the emitter of the triode. In circuit C, it is assumed that the base voltage is 5V and the base current Ib=(5V-0.7V-UL)/4.7K, where UL is the voltage drop across the buzzer. If the UL is relatively large, then the corresponding Ib is small, and it is very likely that the IB is 0.2 Ma and the IC is 20 Ma, and the buzzer cannot be driven.
