Common knowledge of agricultural machinery maintenance: Six methods for energy saving of agricultural diesel engines

1. Improve the temperature of diesel engine cooling water The normal water temperature of agricultural diesel engine is 65-95°C. However, the current temperature of diesel engine water is generally lower than 45°C, so that the oil can not be completely burned and the viscosity of oil is large, which increases the running resistance of the diesel engine. More oil. The solution is to increase the temperature of the diesel cooling water.
2. Ensure that the optimal angle of advancement of the oil supply in advance angle of the 195 diesel engine is 16-20 degrees. When the diesel engine is used for a period of time, due to the wear of the plunger coupler and the injection pump transmission member, the advance angle of the fuel supply is reduced and the fuel consumption is greatly increased. The solution is to ensure that the advance angle of the fuel supply is greater than the optimal angle.
3. Keeping the machine free from oil leakage At present, the diesel engine oil pipe often has oil leakage due to uneven joint surfaces, gasket deformation, or damage. Solution:
1 Apply gasket sand to the gasket and flatten it on a glass plate to calibrate the tubing connector.
2Increase the diesel recovery device. Bicycle spoke caps can be used instead of hollow screws to weld on the tank. Plastic pipes can also be used to connect the return pipe on the nozzle to the hollow screw so that the return oil flows into the tank.
4. More than half of the failures of the diesel engine before the oil was purified were from the oil supply system. Solution:
1 The diesel that was bought back was set aside for 2-4 days, and 98% of the impurities in the diesel could be precipitated when used.
2 If you buy it now, put two layers of silk or toilet paper on the fuel tank filler screen to remove impurities.
5. Changing the "big horse-drawn car" approach The common phenomenon of "large machines with small pumps" on wells is actually a waste of energy. Improvement measures: appropriately increase the number of diesel engine pulleys, increase the speed of the pump when the diesel engine is running at a reduced speed, and increase the flow, lift, and shaft power to achieve the purpose of energy saving.
6. Adjust the injection pressure of the injector. The injection pressure of the 195 diesel injector is 120 kg/cm2. When the injection pressure is less than 100 kg/cm2, the fuel consumption will increase by 10-20 g/kWh. The pressure on the injection pump can be checked and adjusted directly with a comparison method.

Medical Sterilizer are mainly used for rapid sterilization in operating rooms,orthopaedics,stomatology,ophthalmology,otorhinolaryngology,and laboratories,and sterilization of grease,oil yarns,etc.in the supply room
Medical sterilizer fast:5-10 minutes for the whole process,with a heat sink,which can be used again in 4-5 minutes.
Medical sterilizer convenience: Automatic control:set parameters,start the work button,and automatically complete the entire process.
Medical sterilizer In the event of a malfunction,an alarm sounds and the digital tube flashes Err to alert the operator.
There is a prompt tone at the end and no special supervision is required.
Medical sterilizer safety:Sterilization source is a light source that is harmless to human body
Medical sterilizer ultra high temperature protection system,more than 310,automatic power off to stop working.
