What are the aspects of digging tiller needing attention in operation and maintenance?
- Oct 08, 2017 -

    In life, often to use the digging machine, digging machine is widely used, and now its development is getting better and better, then, when using it, how do we need to operate and maintain it?


    1, how to find the actual effect and meet the time requirement in the operation of the digging machine? To finish the homework according to the standard is not the only requirement. On the basis of guaranteeing the quality of the homework, we should shorten the operation time and improve the operation efficiency. This will both provide time for production and reduce expenditure. Plan in accordance with the mechanical operation, to the local block division before operation, determine routes, training standard work hand, do all the preparatory work to be integrated into materials, machinery matching and marshalling, take the normal operation method will be reduced to the minimum load and waiting time.


    2, mechanical maintenance what are the main requirements? Mechanical maintenance according to the "prevention before cure, keep in repair principle, the effective implementation of technical maintenance procedures, power machinery according to the main fuel consumption determine the maintenance cycle, on time, according to the number, according to the study, according to the technical requirements for maintenance, to achieve technical maintenance standards, ensure the equipment in good technical condition. Mechanical maintenance should be strictly in accordance with the provisions of the instructions. The advanced maintenance of machinery shall be conducted indoors. Fuel power machinery to achieve four: no leakage, no leakage, no leakage, no leakage Water Leakage; five net: oil, water, gas, tools and machinery; six seals: diesel tank mouth, gasoline tank mouth, oil filler oil, examine mouth, carburetor, magnetic motor; a good technical shape state intact; supporting tools to implement annual repair, do three: operation, flexible rotation, flexible lifting; five: not open, not blunt, no deformation, no corrosion, no missing parts.

 

    3, which kinds of oil are used in machinery? What are the main features of diesel performance? In the operation of pit digging machine, the oil cost accounts for 1/3 of the total cost. At the same time, the correct use of oil can prolong the service life of the machine and reduce the repair cost. It is of great significance to improve the production efficiency. Commonly used oil for pit machines include gasoline, diesel, lubricating oil and grease. For the commonly used grease, we should be familiar with their specific properties, so that we can make good use of them, so that they can be safe, efficient and low consumption. Diesel is the main "grain" of machinery. When in use, we should understand the following performance indexes: viscosity. It is the index of the consistency and fluidity of diesel oil at normal temperature. Large viscosity, difficult flow, physical and chemical quality is poor, uneven mixing with the air, burning easily smoke; low viscosity, column ring seal is not good when the leakage, forming an oil film, parts easy to wear. Freezing point. Is that oil mobility lost when the temperature drops to make diesel lose liquidity and solidification temperature as pour point. In order to make the normal operation of the engine at low temperature, for diesel oil with low solidifying point. Flash point. Under the specified conditions, the oil is heated and the vapor is mixed with the air to contact the flame. A flash occurs when the oil temperature is called a flash point. The flash point indicates the stability of the oil at high temperature.

 

   4, how to identify light diesel, heavy diesel oil true and false? Check the yellow light diesel oil as normal, surface bluing, and diesel, after shaking the bubbles, and disappeared quickly, feeling when you feel smooth, hands after feeling. Heavy diesel normal brown, from the smell of diesel, some odor smell after shaking, with yellow, and disappeared rapidly, touch feel smooth and greasy hand.
