Do not use agricultural machinery oil instead of agricultural machinery gear oil and compared with gear oil, low viscosity, wear resistance and load capacity is also weak. If the agricultural machine oil is used instead of the agricultural gear oil, the transmission gear will not be well lubricated, which will result in serious wear of the gears of the transmission system.
Do not use agricultural machinery oil instead of agricultural machinery brake oil. Brake fluid has good solubility and corrosion, and it is not easy to produce precipitation. Agricultural machinery oil does not have the above characteristics. If used in place of agricultural machinery brake oil, it is easy to produce precipitation, and will make the brake system rubber. Device expansion causes brake failure.
Do not use farm machine oil instead of farm diesel oil. Agricultural machinery oil is less viscous than agricultural machinery, and it has a high ignition temperature. If agricultural machinery diesel oil is used instead of agricultural machinery diesel engine, the diesel engine will not only be difficult to start, but also will cause increased wear of the cylinder barrel and piston.
Fetal Doppler applies ultrasonic doppler principle to obtain the movement information of fetal heart from abdomen of pregnant women, enlarge the signals, and output them from earphones so as to calculate the value of fetal heart rate.
