Technology Progress in Wind-driven Water Elevator in China

Technologies on wind-driven water elevator have achieved obvious advancement in China. While the Chinese Agricultural Mechanism Research Institute of Sciences and Xinhua tractor factory were researching the FDG-5 type wind-driven water elevator, they employed measures including the improved flank and bob-weight speed adjustment system, allocated tools for screw pump and wind wheel vane which has comparatively high wind utilization co-efficient, making the overall performance of the sets increase greatly. This sets endured the attack by the typhoon and salt frog while the demonstration and experiment were conducted on Jiangxu and Tianjin, fulfilling the prospective experiment target. Another example was regarding the FD-4 type wind-driven water elevator, while Hohehot Animal Husbandry Mechanism Research Institute was developing; they adapted the empennage pintle inclined speed-governed institution, effectively ensuring the safe operation of the sets. Moreover, it can be used allocating with tie rod pump in order to satisfy the various requirement on lift and flow rate by different water well. The advance in Chinese wind-driven water elevator industry has attached the importance of the international counterparts.
