Solar LED street lights illuminate in rainy days
Solar LED street lights are devices that use solar energy to convert electricity into electricity. How to illuminate if the sun does not appear for a long time? Of course, the solar LED street light will still be illuminated in the same way. Here is a brief explanation of the reasons:
1. The ability of the battery to store electrical energy Even if the solar panel can convert more power, if the battery can not store electrical energy, then it is wasted. Therefore, we must have sufficient storage capacity. This is mainly combined with solar panels. It is generally considered that the higher the storage capacity, the better;
2. The ability of solar panels to convert solar energy into electrical energy per unit time. This is mainly due to the problem of conversion capacity and panel size. If there is frequent rainy weather or long rainy weather in a certain area, large solar panels should be considered. ;
3. The ability to save resources during the discharge process Solar LED street lamps are devices that use solar energy to convert electricity into lighting. When equipment lighting is used, the utilization of electric energy is high, and the discharge loss is reduced, thereby achieving the goal of energy saving.
Angular contact ball bearing can withstand both radial load and axial load. Able to work at a high speed. With larger contact angle, the axial capacity of the bearing will be higher. High precision and high speed bearings usually have a 15 degree contact angle. The contact Angle will increase under axial force.
Angular contact ball bearing accuracy class includes dimensional tolerance and rotation precision.The precision is expressed as P0(ordinary), P6(P6X), P5, P4 and P2.In addition, the European and American brands also use P3, P7 and P9 to indicate the accuracy level. P3 is the P6 level of ISO and JIS standard, P7 is equivalent to P4, P9 is equivalent to P2.
Double row angular contact ball bearing application are: oil pump, roots blower, air compressor, all kinds of transmission, fuel injection pump, printing machinery, planetary reducer, extraction equipment, cycloid reducer, food packaging machinery, electric welding machine, electric, square box, gravity type spray gun, wire stripping machine, axle shaft equipment, chemical machinery, testing analysis equipment.
