Tractors are powered by diesel engines, but diesel engines should not be operated at low speeds for long periods of time. The reason is as follows: The atomization quality of the injector is mainly related to the injection pressure, the diameter of the injector and the rotation speed of the camshaft. Since the injection hole diameter is fixed, the quality of the atomization of the diesel engine depends on the pressure of the injection nozzle and the cam rotation speed. The greater the pressure of the injection nozzle, the faster the camshaft rotation speed, the better the atomization of the fuel injection, and the camshaft. The rotation speed varies with the crankshaft rotation speed. When the diesel engine speed is lower than the rated rotation speed, the atomizing quality of the injector exhibits a supersaturation state. Once the time passes, the diesel engine will not operate normally. When the diesel engine is overloaded, the temperature of the engine increases and the temperature of the oil rises. As a result, the oil pump is insufficiently supplied at a low speed, resulting in poor lubrication of the associated parts. When the speed is low and the work is not stable, the connecting rod and the bearing bush are used. The parts will also work under abnormal loads, resulting in accidents such as dropping of the bearing alloy.
Neck Massager
Whether it's from sleeping weird, working out too hard, or sitting hunched over for hours staring at your computer, most of us have dealt with kinks in our necks from time to time. According to a peer-reviewed article from Marco Funiciello and Zinovy Meyler, Doctors of Osteopathic Medicine, one of the best ways to soothe aches and pains in your neck is through massage therapy.
While going to a massage therapist can be a relaxing experience, it can also be quite expensive. So if you don't have the time or money to get a professional massage, investing in a portable, at-home neck massager is a cost-effective alternative. The handy gadgets can knead out tight knots and melt stress away with ease.
There are many kinds of neck massagers on the market, including portable handheld models, devices that wrap around your neck, and even manual massager rollers. Some boast special features like adjustable heating controls so you can apply heat therapy to painful spots, while others are designed to target pressure points for migraine relief.
