In addition to the special importance, the interaction between these features will enhance or diminish the end user's feelings. In general, when users start to notice the presence of the battery , things become more difficult! Good design does not require frequent replacement of the battery (e.g., TV remote control), does not require frequent charging the battery (electric toothbrushes), make the battery "disappear" out. Avoid users paying attention to the battery as much as paying attention to the function of the device. Select the chemistry of the battery The mutual constraints between the battery and the system are often overlooked in the design, and it is critical to ensure that the battery capacity matches the requirements of the system. Commonly used battery types are: alkaline batteries , nickel-metal hydride batteries (NiMH) and lithium-ion batteries . They are not interchangeable, and most products have an optimal solution. Alkaline battery Alkaline batteries are non-rechargeable batteries (this has been repeatedly emphasized in recent evening battery advertisements), but they have extremely low self-discharge rates and costs (no charger or AC outlet required). For low power applications, alkaline batteries will be a good choice, but they must be used reasonably, and the quiescent current or sleep current must be low. A common misconception in design is that it only focuses on work efficiency, while ignoring the current loss in the "off" or "sleep" state, even if the current consumption of tens of μA from the battery will cause frequent replacement of the battery . Nowadays, many designs use soft switches instead of mechanical switches (mechanical switches can completely disconnect the battery ), but this design misunderstanding is more common than it was a few years ago. Rechargeable battery When the load is too large for an alkaline battery , a rechargeable battery is required , which has become a standard mode for portable products such as notebook computers, PDAs, and cellular phones. Rechargeable batteries should "disturb" the user as little as possible, and promote the product, at least not to degrade the performance of the product. There are two options rechargeable battery: a nickel hydrogen battery or a lithium ion battery. NiMH batteries cost less than lithium-ion batteries , and this option becomes very sensitive when the product's regular use is unsafe for the battery . This problem is more important for low cost products that lack complex charging designs because NiMH batteries are suitable for processes that are fully charged and fully discharged. This is suitable for products that often exhaust power completely, such as power tools. Application of a further alternative for NiMH batteries alkaline battery, i.e. the battery is removed from the device when the battery power is exhausted, then the battery is charged by an external charger. Such applications are more common in digital cameras, but require frequent user intervention. Many portable products are different from the above. PDAs and cellular phones need to be recharged regularly, but they only consume power occasionally. These products are best used in lithium-ion batteries . In addition to their weight density, these batteries have two important advantages: low self-discharge rate, and no restrictions on short-time charge-discharge. Consumers don't have to think about " battery management" issues, simplifying product usage. OTO Pulley type wire drawing machine
The first Safety precautions for LZ600 wire drawing machine
1. 1 Professional and technical personnel are required to carry out installation and commissioning. Before use, it is necessary to carefully read this manual and the relevant electrical instructions provided.
1. 2 Each machine and electric control cabinet shall be reliably grounded with a grounding resistance not more than 4Ω.
1. 3 There should be no accumulated water on the table top, especially near the operation box, as it can easily lead to circuit failure due to water infiltration.
1.4 It is prohibited for multiple people to operate the same equipment at the same time to avoid accidents.
1. 5 The electric control cabinet should be placed in a clean and dry room, and the door should be closed when working to prevent dust intrusion from causing device performance degradation or failure. Air conditioning is used to maintain the ambient temperature of the electric control cabinet. Frequently check the operation of the cooling fan on the top of the electric control cabinet.
1. 6 Before starting the machine, check whether the safety device is normal.
1. 7 Do not operate the components in the electrical cabinet with power. After cutting off the main power supply, wait at least five minutes, and wait until the intermediate circuit capacitance is discharged before operating the frequency converter, motor, or motor cable.
1.8 Do not touch the IC circuits on the inverter control interface board and motor control board, as static electricity may damage these circuits.
1.9 Please provide the power supply and operating environment according to the technical requirements of Section 3.2. It is not allowed to arbitrarily change the parameters of the frequency converter and PLC. The user shall be responsible for any damage to electrical components caused by human factors.
The second Delivery inspection
2. 1. Check whether the equipment is damaged and complete upon delivery (according to the packing list). If there is any damage or inconsistency with the contract, please contact the dealer or manufacturer immediately.
2. 2 The manufacturer is only responsible for quality issues arising during production, and is not responsible for damage caused during unpacking, improper installation and use, or damage caused by overload operation.
2. 3 After unpacking, the accompanying documents should be properly kept, as they are necessary during equipment installation, commissioning, and use

 The key indicators of the battery, of course, is battery life. On the surface, this is a simple specification, but it involves many factors, including: system load (full load current supply time, part of the circuit or micro-ampere current supply time), power efficiency, system power management , battery type and charging method.
