How to save energy and reduce emissions in agricultural machinery maintenance

saving energy and reducing emissions in agricultural machinery maintenance is to save costs and increase efficiency, which is the concern of the majority of machine operators. Spring ploughing is also the peak period of the use and maintenance of agricultural machinery. In order to save energy and reduce emissions, we should mainly master these key technical points -

effect: according to the test statistics, using the fuel injection pump debugged on the calibrated fuel injection pump test bench, each pump saves an average of 5%. At the same time, the calibrated fuel injection pump can ensure the good working condition of the diesel engine, help to prolong the service life of the diesel engine, reduce noise and reduce exhaust emissions

fuel injection pump and fuel injector Commissioning Technology

meaning: under the specified conditions, according to the correct maintenance process and commissioning method, the fuel injection pump and fuel injector are repaired and commissioned to achieve their due functions

the main technical contents include: the determination of the oil supply starting position of each cylinder of the fuel injection pump, the inspection and adjustment of the oil supply volume, the inspection and adjustment of the tightness of the fuel injection pump assembly, the inspection and adjustment of the governor characteristics, the inspection and adjustment of the accessories of the fuel injection pump, the inspection and adjustment of the fuel injection pressure of the fuel injector, the inspection of the atomization quality and its distribution, the inspection of the tightness, as well as the requirements of the working environment, technical conditions and equipment configuration of the commissioning. Effect of imported pump Custer red wine

according to the sampling inspection of tractors in use, the fuel consumption rate of small tractors is 13.4% higher than the calibration value on average, and that of large and medium-sized tractors is 6 ~ 10% higher on average. Particulate emissions should be repaired in time by adding other materials such as non-metal and metal to pure resin, or organic materials exceed the national standard by 4 ~ 5 times. After the precise commissioning of the fuel injection pump and injector of the high-pressure oil circuit of the tractor diesel engine according to the regulations, the energy consumption and emission can be significantly reduced, and its working performance can be restored or improved

diesel engine performance adjustment and optimization technology

meaning: the use of advanced instruments and equipment will also provide an inexhaustible driving force for the extruder industry to detect the technical status of the diesel engine, optimize and adjust various technical parameters, so as to restore the good technical state of the diesel engine

the main technical contents include: detection and optimization of injection pressure, injection advance angle, valve clearance, valve timing, cylinder pressure, speed, oil pressure and outlet valve pressure holding time

effect: according to the test statistics, the diesel engine can generally increase its power by 8 ~ 15%, reduce the fuel consumption rate by 10 ~ 20%, reduce the engine failure rate by 14.6%, reduce the maintenance cost by 13.5%, reduce the maintenance man hour by 24.8%, and reduce the maintenance downtime by 16.8%

tractor non disassembly detection and debugging technology

meaning: it is a technology that uses advanced instruments and equipment to carry out non disassembly rapid detection and technical evaluation of the tractor's comprehensive technical status, and takes corresponding maintenance and debugging measures to keep the tractor in good running condition, so as to achieve the effect of energy conservation and emission reduction

the main technical contents include: comprehensive testing of tractor power, fuel consumption and emissions, as well as special testing and repair of transmission system, hydraulic system, braking system, etc

effect: according to the test statistics, 8055 tractors were tested without disassembly, and 4430 tractors with poor technical status were tested. After commissioning, the technical state of the tractor has been significantly improved. Before commissioning, the average power is 7.35 kW, the average fuel consumption rate is 340 g/kWh, and after commissioning, the average power is 8.16 kW, the average fuel consumption rate is 299.2 g/kWh. A total of 3588 kW of power has been restored, and the average fuel consumption per unit is 120 kg/year

lubricating oil timely replacement technology

meaning: regularly detect and analyze the quality of agricultural machinery lubricating oil, and timely change the oil according to the oil change standard, so as to ensure good lubrication of agricultural machinery. At the same time, monitor the changes in the technical status of agricultural machinery and determine the maintenance strategy of agricultural machinery

the main technical contents include: the detection technology of the physical and chemical performance indexes (viscosity, acid value, moisture, impurities, water-soluble acid and alkali) of lubricating oil, the determination of the oil change standard and oil change cycle of lubricating oil, and the analysis of the working state of the relevant systems of lubricating parts

effect: a fixed oil change cycle is usually adopted for the replacement of agricultural machinery lubricating oil. Adopting the technology of regular detection, analysis and timely replacement can avoid replacing the lubricating oil with good quality according to the fixed cycle, reduce the amount of oil replacement, save resources and reduce the pollution of waste oil; It can also be found that the quality of lubricating oil has deteriorated before the replacement time, so as to avoid poor lubrication conditions, increased wear and serious mechanical failures

water based cleaning technology

meaning: a new environmental protection cleaning technology that uses water as the cleaning medium, uses water-based cleaning agent instead of organic solvent, and combines different cleaning methods to quickly and efficiently remove dirt from parts. Water based cleaning agent is a mixture of a small amount of surfactants, washing AIDS, corrosion inhibitors, solubilizers, defoamers, foam stabilizers and other chemicals added to the water. It can replace flammable and dangerous petroleum solvents and remove dirt such as oil stains and dye mildew on the surface of metal parts

the main technical contents include: the selection and preparation of water-based cleaning agents, the application of high-pressure cleaning, ultrasonic cleaning technology and other cleaning methods

Water based detergent can not only dissolve and remove all kinds of water-soluble dirt, but also remove non water-soluble dirt such as synthetic resin and fat
