In the summer operation, the diesel engine is prone to excessive temperature, resulting in thermal expansion of the machine and causing the cylinder to inflate and reduce the power. Therefore, the technical status of the cooling system directly affects the work of the diesel engine, and it is particularly necessary to strengthen the maintenance of the cooling system. Regular cleaning of cooling system Cooling system is easy to affect scale and heat dissipation. Each model should be cleaned as required. For example, type 290, 295 diesel engine is operated for 1000 hours and type 485 diesel engine is to be cleaned after 720 hours. Cleaning method: Exhaust the cooling water, remove the thermostat, add the cleaning solution (preparation method: add 4.5 kilograms of caustic soda and 60 kilograms of kerosene in 60 liters of water), start the diesel engine, and run at a speed of 5-10 minutes while the water temperature rises. Turn off at 70-80°C, let it stand for 10 hours, and start to run at medium speed for 5-10 minutes. Then heat the cleaning fluid, add clean water, and run at medium speed for 4-5 minutes. Times. Pay attention to the use of water to check the water level of the water tank before starting the diesel engine; the water level of the closed cooling water tank must be higher than the radiator core orifice, and must not be less than 8 cm of the overflow nozzle. Soft water such as pond water, river water, and rain water can be used. Hard water such as boiled water and spring water cannot be added. If there is no soft water, hard water can be boiled and precipitated. Do not change the cooling water arbitrarily. The used cooling water has softened and the minerals have precipitated. When the machine temperature is too high, it is not appropriate to add water immediately. After the engine is idle for a few minutes, the cooling water should be added slowly to prevent the body from being quenched or cracked. When the lid of the tank is opened, the head face should not be aligned with the cover of the tank to prevent water leakage. Vapor blows out of the scald. Strengthen the inspection of components Periodically check the thermostat to prevent the failure of the thermostat. The body is overheated: Remove the thermostat, remove the oil and put it in water. Normally, when the water temperature rises to 70°C, the main valve should be Begin opening and fully open at 80-85°C. Pay attention to adjust the tension of the fan belt. For example, the fan belt of the 195 diesel engine is suitable for pressing down 20-30 mm with 4 fingers; otherwise it should be adjusted; usually, oil and exposure on the belt should be avoided, such as the aging of the belt or Cracking should be replaced promptly; if crankshafts, fans, and generators have three different pulleys (not in the same plane), they should be adjusted.
Probiotics Powder
Probiotics are a kind of active microorganisms that are beneficial to the host by colonizing in the human body and changing the composition of the flora in a certain part of the host. By regulating the host mucosa and the immune function of the system or by regulating the balance of intestinal flora, promoting the absorption of nutrients to maintain intestinal health, thus producing single microorganisms or a well-defined mix of microorganisms that are conducive to health effects.
Probiotics Powder has many benefits. It's a Nutritional Supplements.
Probiotics can synthesize digestive enzymes. Together with the digestive enzymes synthesized by animals, they participate in the digestion of nutrients in the intestine, stimulate the secretion of digestive enzymes in the animal body, reduce the depth of small intestine recess, increase the villi height, increase the surface area of the small intestine, and promote the absorption of intestinal nutrients. Probiotics can also be used as Food Additives.
Probiotics' own structure, such as peptidoglycan, lipoteichoic acid and other components, can act as antigens to directly activate the immune system, or stimulate the host immune system through autocrine immune activators, thereby improving the immunity of animals, enhancing the activity of the body's innate immune cells and natural killer cells, activating dendritic cells, and stimulating the body to produce cytokines. And stimulate B cells to secrete antibodies, probiotics can stimulate the gut to produce secretory globulin A (SIgA), protect body health.
