The new product of improving the efficiency of the new oil ,BS-LBQ 　　Mechanical gear shift ground-driven devices 　　Mechanical gear shift ground-driven devices is a new type of fuel pumps driven devices used in moving the single pump to get the oil . It is cohesive and easy to operate,with the release of security. such as the use of reliable features of the original settlement-driven devices that ordinary Senate gear shift, the traditional religions are operating in belt pulley, overcome frequency conversion governor outer operation due to temperature effects light show the governor out there (for the summer high surface temperature) and electrical steal stopped (because winter temperatures too low) phenomena. The devices use mechanical transmission theory, spiral bevel gear and climbing gear in combination. A changed stalls handle can adjust 4 kinds of speeds. Export axis rotational speed : 50r/min, 80r/min, 98r/min, 160r/min. Application-ray pole : φ 28, φ 32, φ 34, φ 36 exporting power 11KW, 15KW, 18.5KW and 22KW. This device shortens the operating time of rotation in the Senate gear shift and improves the efficiency of oil. Compared with the transducer governor devices ,it has reduced oil input costs. The use of new devices with the outside firm and mixed textile V-shaped rubber Mifengjuan (closed-ray pole)can be used safely and reliablly. The mechanical gear shift ground-driven devices for oil mining will make a great record of the better economic interests. In 2006,we have received the national patent.
