Batteries can be roughly classified into wet batteries and dry batteries. Dry batteries can be opened and filled without a cover. Therefore, under normal circumstances, it is not necessary to perform maintenance. New batteries need to be replaced in normal use for two years. The second wet battery need to pay attention to the scale of the battery water can not be lower than the lowest tick mark when used in peacetime, but it can not be higher than the highest tick mark, if the water is missing, then it should be timely The refilled distilled water or the battery refill solution can not be added to the original solution, so as to prevent the concentration from being too high. If it is not used for a long time, the battery needs to be fully charged after being started again. Hand-held vacuum cleaners and water bottles maintenance methods: 1. When the battery of the hand-push vacuum cleaner is used for the first time, the charge time of the first three times should be higher than 14H, and it can be filled after it is recharged. Half of the battery charging time is about 8H. If you use those relatively large currents, the charge time will be shortened, but the high current will shorten the life of the battery. Charges can be made during off-hours every day, and the charger can be disconnected on the morning of the next day. When the battery is fully charged, the charger automatically stops and charges the battery. 2. The battery of the hand-push vacuum cleaner sweeps the liquid level in about 10 days or so. If the liquid level is approaching the lead plate quickly (it is necessary to pay attention here, it is not possible to leak the air in the air. In the middle), you should immediately drop the distilled water. When you add water, it takes about 3mm from the plastic mouth. You can't add pure water, tap water, or the battery's original solution without authorization. 3, hand-push vacuum cleaner The battery should be carried out after the battery is fully charged. 4. When using the battery each time, it is better to leave 20 to 30 percent of the remaining power in the battery. Too much discharge will directly affect the service life of the battery. 5, the battery should be charged within 24H after the battery is discharged, otherwise it will damage the battery. 6, push-type vacuum sweeper during charging of the battery, it should be contacted to confirm whether the power supply is abnormal situation good socket, the plug and the plug of the charger to the battery contacts are good. 7. If the battery is not used for a long period of time, the battery should be recharged every 3-2 months. 8. If there are oxides on the battery post and the wire connector, it should be cleaned in time. (Text / Sun Ni)
Automatic electric chuck, claw DC motor drive, clamping motor current is sensitive, adjustable and stable, clamping range is wider and clamping force is larger. Non - destructive pipe clamping, fast automatic centering and clamping pipe, performance is more stable. The chuck size is smaller, rotation inertia is low, and dynamic performance is strong. Self-centering electric chuck, gear transmission mode, higher transmission efficiency, long working life and high work reliability.
