There are three types of self-propelled elevators. No matter which type is selected, maintenance is required after use, but there are some differences in the maintenance skills of each type. The place for frequent maintenance is to check the normality of the power supply and whether the internal structural components are rusted. Wait for the situation. Now the editor will introduce some specific methods for the maintenance of self-propelled elevators.
The power of self-propelled elevatorsEscalator manufacturers is rich and diverse, which can be roughly divided into three forms: alternating current, diesel engine and direct current. Direct current usually uses a battery as the main power source, which can realize one-key lifting without an external power supply. Then, for this type of self-propelled elevator, the battery What are the skills in use and maintenance? Share with you.

  

 

         ①The battery charging and discharging process cannot be reversed. The battery cannot be reversed during charging or discharging, because the reverse connection of the DC power supply may cause short-circuit or even explosion hazards. Therefore, check the positive and negative poles and do not reverse the connection.
  ②Perform regular inspections. If there is a short-circuit phenomenon such as broken grids, softening of the electrode plates, and loss of active material on the electrode plates, etc., a battery. At this time, you should go to a professional battery repair organization for inspection, repair or assembly in time.
  ③It is strictly forbidden to store under power loss. The underpowered state means that the battery is not charged in time after use, and it is prone to sulfation. Lead sulfate crystals are attached to the plate, blocking the ion channel, causing insufficient charging and reducing battery capacity. The longer the idle time of the electric lifting platform under power loss, the more serious the battery damage. When the battery is not in use, it should be charged once a month, which can prolong the service life of the battery.
  ④ Grasp the charging time, the average charging time is about 8 hours. If it is shallow discharge (the mileage is short after charging), the battery will be fully charged soon, and overcharge will occur if the battery continues to charge, which will cause the battery to lose water and heat, and reduce the battery life.
  ⑤Do a good job of battery safety protection to prevent high temperature exposure and strictly prohibit exposure to sunlight. An over-temperature environment will increase the internal pressure of the battery and the battery pressure limiting valve will be forced to open automatically. The direct consequence is to increase the battery's water loss. Excessive battery loss will inevitably lead to a decrease in battery activity and accelerate the softening of the plate. Fatal injuries such as body heat, bulging and deformation of the shell.
  ⑥ It is strictly forbidden to use it during the charging process. In order to save time, some customers will charge while using it. This will seriously shorten the service life of the battery and even cause safety hazards. Therefore, try to choose the night time or leisure time to charge the battery.
In short: self-propelled elevators use batteries as a power source, which reduces constraints, facilitates outdoor operations, and is not restricted by external power sources. Therefore, if you want to use it for a long time, you must maintain the batteries, so that you can Make better use of the excellent performance of self-propelled lifts.
