Maintenance requirements for individual components of pure electric cars
Whether it is a fuel vehicle or a pure electric vehicle, the maintenance of the vehicle is an important link. Only the vehicle components can be well maintained and maintained, and the high-quality driving performance of the vehicle can be guaranteed. Then the following brief introduction for the maintenance of the pure electric vehicle power battery box and motor system.
Pure electric vehicle motor maintenance: daily need to drive a pure electric vehicle, you should check in advance whether the antifreeze in the tank is still sufficient, if the amount of antifreeze does not meet the required standards, it should be promptly filled. After every six months, the controller and the electric motor of the pure electric vehicle need to be dusted. After the power supply of the vehicle is disconnected, the high-pressure air gun can be used to clean the dust of the controller and the motor, and then use clean soft. The brush is clean, and it should be noted here that it is not possible to use a high-pressure air gun to blow the respirator above the housing of the controller. Every 60 days or so, it is necessary to do a check for the controller of the vehicle and the water tank to see if the water cooling pipe is smooth. If there is any blockage, it must be cleared out in time.
Power battery box maintenance for pure electric vehicles: Before installing the power battery inner box of a pure electric vehicle, it is necessary to endure to check whether the rubber jacket of the lower pole seat is complete and complete. There is no oxidation of the poles. If there is a slight oxidation surface, the oxide surface can be lightly polished using a l500-grit sandpaper, or it can be wiped with a cotton cloth and then the oxide layer can be cleaned. The power battery box of a pure electric vehicle needs regular cleaning of dust in the outer box. If it is sparked or arcing occurs, it must be replaced immediately. If the 24V power supply has poor or poor communication, check the 24V connection plug and the CAN cable connection plug. The last step is to conduct a detailed inspection on the high-voltage positive and negative pole sections of the power battery outer box of a pure electric vehicle, and use a megohmmeter 500 V block to measure the insulation resistance of each terminal. If the jack of the pole and the plug of the high voltage pole have no ablation, wear, etc., and check whether the relevant parts such as the lower protective sleeve are complete.
Xinxiang SKF Machinery supply whole set of grinding solution, including the Grinding Oil Filter Paper.
Production introduction:
In the grinding oil, there are always mixed with oil slick, impurity, slag, etc. It should be cleaned regularly, or the grinding efficiency and lifespan will be reduced largely and finally influence the equipment grinding efficiency. At the same time, when the grinding oil was covered by the closed oil reservoir, the anaerobion can easily breed, this will result in grinding oil invalid. So to clean the
oil slick, impurity, slag out from the grinding oil is very important, in this way we can not only keep a good grinding oil performance but also expand the grinding oil life largely. At last, reduce the grinding oil cost, improve grinding life and efficiency!
