With the arrival of the spring plowing season, the “iron cows†that have been rehabbing for a winter have come to the grand exhibition. However, when the agricultural machinery and equipment are used, they must pay attention to several points in order to ensure the smooth operation of the agricultural machinery bureau and the smooth development of the spring plowing work. of.
1. Do not start to lift the clutch. Slowly release the clutch pedal while properly increasing the throttle. Otherwise, it will cause impact on the clutch assembly and transmission parts, and even damage.
2. The tractor is forbidden to open the gear or step down the clutch to slide downhill.
3, tractor shift and working speed selection. Choosing the correct working speed of the tractor will not only achieve the best productivity and economy, but also extend the life of the tractor. When the tractor is working, it should not be overloaded frequently and the engine must have a certain power reserve. The speed of tractor field work should be chosen so that the engine is working under about 80% load.
4, under normal circumstances, should first reduce the engine throttle, and then step on the main clutch pedal, and then gradually depress the driving brake operating pedal, so that the tractor stopped. In case of emergency braking, the main clutch pedal and the service brake operating pedal should be depressed at the same time. During driving, the driver is not allowed to place his or her foot on the brake or clutch pedal. Special reminder: When the tractor is driving on the road, the left and right brake pedals must be interlocked. When the tractor is parked on the slope, it is necessary to hang up the gear before releasing the brake pedal after the engine is turned off, hang the forward gear when going uphill, and hang up the gear when going downhill.
5. When the tractor is working in a heavy field in the field or working on a damp, soft soil, it is usually attached to the front drive axle to realize four-wheel drive operation. When the tractor is used for general transportation on hard roads, it is not allowed to engage the front drive axle, otherwise it will cause early wear of the front wheels.
High flow oxygen therapy (HFNC) is a kind of oxygen therapy that directly transports a certain oxygen concentration of air oxygen mixed with high flow gas to patients through a soft nasal cannula. Also known as transnasal high flow oxygen therapy, high flow humidification oxygen therapy. HFNC has unique physiological effects: Constant oxygen concentration, Good effect of temperature and humidity, To flush the dead space of the nasopharynx, Give some positive airway pressure, Good comfort.
