The invention relates to a method for collecting CGP catalysts through a tank car. The method includes the following steps that first, the catalysts are transported through the tank car, and namely the CGP catalysts are directly placed into the closed powder tank car and transported to a production field through the tank car; second, the tank car is pressurized through an air compressor, and namely the air compressor in the tank car is started, the tank car is pressurized through the air compressor, and the pressure in the tank car is made to reach 0.35MPa; third, a catalyst cooling tank and the tank car are connected, and the catalysts are conveyed into the catalyst cooling tank. Through the method, environmental pollution, catalyst loss and energy loss are reduced, labor cost is greatly lowered, labor intensity of workers is relieved, the catalyst collection time is shortened, and influences on device operation are reduced.

The invention discloses a high and low speed shaft turning gear of a high power wind generation set and a using method thereof. The high and low speed shaft turning gear of the high power wind generation set comprises a main gear box, an externally arranged hydraulic source, a hydraulic motor, a motor shaft gear, an intermediate level gear, a wind wheel, a low speed level gear, a high speed level gear, a brake disc, an intermediate level shifting gear, a shifting mechanism and a shifting controller. According to the high and low speed shaft turning gear of the high power wind generation set and the using method, the hydraulic motor and the shifting mechanism are driven by a hydraulic system to achieve the self-turning function of a low speed shaft and a high speed and the locking of the wind wheel; the separate turning of the high speed shaft is achieved when the high speed shaft needs to be centered, so that the problem that start-stop of the low speed shaft which performs turning together with the high speed shaft causes the low accuracy of centering data collection of the high speed is solved, the influence of the wind conditions of a wind field on turning operation of the high speed shaft is reduced, and the efficiency and safety of the turning operation of the high speed shaft is improved; the problems that the turning is difficult and the artificial demands are multiple in a wind power station are solved and the high and low speed shaft turning gear is efficient, safe and labor-saving.

Disclosed are an engine self-adaptive system and fuel saving method based on vehicle operating condition, the engine self-adaptive system comprising an information center and vehicle terminals in communication with the information center. Each vehicle terminal comprises a GPS navigation module, a running vehicle data collection module, a vehicle specifications and engine operating states memory, a wireless communication module, a calculation module, a decision-making module, a vehicle control module, and a human interface module. The vehicle control module adjusts an engine response characteristic and reduces the effect of improper throttle operation. A standard road resistance characteristic coefficient is an optimum and has a higher reference value such that the invention, for ensuring power performance for a vehicle, achieves fuel saving by properly controlling engine output.
