after the flow of the oil from the outlet of the impeller flow passage, the oil is guided by the guide groove, thus the directional flow of the oil is made, which makes the center line of the impeller coincide with the central line of the guide wheel, that is, the impeller is suspended, thus reducing the friction between the impeller and the guide wheel, and thus improving the performance of the oil Submersible pump and prolonging the Ye Daolun's performance. The service life.

Linear lamps are mainly divided into traditional linear lamps and LED linear lamps. Traditional linear lamps are mainly used for grille lamps, panel lamps and hanging lamps of traditional straight tube fluorescent lamps (such as T5, T8 and T12); LED linear lamps refer to LED integration. The luminaire also includes linear luminaires that use LEDs to replace the light source. For a long time, the US linear lighting market is dominated by lamps with straight tube fluorescent lamps as the light source. However, after the appearance of LEDs, this pattern has undergone new changes. For example, in 2001, T12 fluorescent lamps accounted for 72% of the total commercial use of linear lamps, accounting for 67% of the total consumption of linear lamps. In 2015, the T12 fluorescent lamps accounted for only the total amount of linear lamps in the commercial field. 7%, the industrial sector only accounts for 12%. According to the prediction of the US Department of Energy, the T12 fluorescent lamps in 2035 account for only 1% of the total occupancy of all linear lamps, while the proportion of LED replacement lamps will increase to 16%. The proportion of LED integrated lamps will be increased. Increased to 61%.
