How to buy agricultural machinery to see trademark, weight and specifications When buying agricultural products and accessories, we must have a trademark awareness. When you purchase accessories, you must first observe whether the specification of the accessories meets the requirements for use. Secondly, we must measure the amount of helium by hand. Most shoddy parts are cut corners, light weight and small size. We must pay attention to identification.
To see if there are product certifications and assembly marks for authentic products that have been qualified by the National Quality and Technical Supervision Department, they will be allowed to pass the production inspection certificate, instructions, and installation notices, if not more than fake and shoddy products.
Look for cracks and distortions. The shoddy and inferior products are viewed from the outside and have a low surface finish. They also have obvious defects such as cracks, sand holes, slag inclusions, and burrs, which can easily cause oil leakage, water leakage, or leakage. In addition, tires, V-belts, shafts, rods, etc., if the storage method is not appropriate, it is easy to deform, geometrical dimensions can not meet the requirements of the use of regulations, it can not be used normally.
See if there is rust and looseness, and the stuck-in product parts have flexible rotation, and the gap size meets the standard specification. Most of the shoddy products are not too loose, that is, they are not flexible. Some parts and accessories may be rusted, oxidized, discolored, deformed, or aged due to poor storage or long storage time. If you have any of the above conditions, you should not purchase it.
Look at the quality of packaging for surface packaging and authentic colors of surface colors. The products are rust-proof, waterproof, and corrosion-resistant. They are packaged in wooden boxes and marked with product names, specifications, models, quantities, and names in prominent locations. Some parts assemblies are packed in paper cartons and set in plastic bags. Fake and shoddy product packaging is rough and poor. If it is a manufacturer's original product, the surface coloring treatment is relatively fixed, and all of them are regulated colors. Therefore, the appearance of the agricultural machine can also be seen from the appearance.
How to maintain agricultural machinery summary Agricultural machinery maintenance technology should be "five nets"
There are three methods for purifying the net diesel fuel: First, the purchased diesel is allowed to settle for more than 96 hours, and then the funnel is added to the filter and a layer of silk cloth is added. When taking oil from the oil drum, take the filter plus a layer of silk cloth or typewriter wax paper, and clean or replace it regularly.
The filter oil of the lubricant oil net oil filter should be regularly cleaned. The rotor filter should be affixed with a layer of suitable kraft paper of a wide and narrow length to facilitate the adsorption of dirt under centrifugal action. The dirt that is adsorbed on the filter element is best cleaned with an air pump and blows air from inside to outside, scrubs with a brush, and never wipe it by hand. Use a clean, calcium-based grease on the butter, and don't mess with other lubricants.
When the air net engine is running, the cylinder draws 2 to 4 cubic meters of air per minute. In order to ensure that the air entering the cylinder is clean, the air filter must be inspected and cleaned regularly.
Cooling water The net engine cooling water is preferably soft water, ie snow, rainwater or treated tap water, clean well water, etc. The cooling system purges 1% caustic soda and 0.5% kerosene in proportion to the water volume.
The net of the implement must be scrubbed frequently so that the fuselage does not rust. If necessary, it can be used to make up the paint to prevent rust.
How to safely use electric farm implements The correct use of electric farm implements should pay attention to the following eight points:
There is a reliable grounding device or temporary grounding device for the metal housing of the grounding device for electric agricultural implements. In this way, in the event that the metal housing of the farm implement is electrified, current will flow into the ground through the ground wire, thus avoiding the occurrence of personal electric shock accidents.
Unable to move the mobile electric farm tools beforehand, it is necessary to turn off the power in advance, and it cannot be moved with power.
Power supply lines The power supply lines for the installation of electric agricultural implements must be installed in accordance with the rules for electricity usage. If the agricultural machinery is far away from electricity, a double knife switch and a capacitor breaker should be installed separately near the agricultural machinery so that the power can be rapidly cut off in the event of an accident.
Without electricity, the maintenance of electric agricultural implements should be powered off and repaired if it fails. At the same time, warning signs such as “Forbidden to close†and “Someone work†should be hoisted, or special guards should be sent to prevent anyone from accidentally closing the knife.
Installation of electric shock protectors Agricultural machinery using single-phase motors must be equipped with low-voltage electric shock protectors. In this way, the power can be automatically cut off in the event of an accident, so that the electric shocker can get out of danger. Low-voltage electric shock protectors should always be sensitive and reliable to ensure safety.
For trial operation of farm implements that have not been used for a long time or are exposed to moisture, they should be commissioned before being put into normal operation. If it does not operate after power supply, it must be immediately powered off to prevent the burning of agricultural machinery and endangering personal safety.
Implementation of the operating rules agricultural machinery operators should strengthen awareness of prevention and strict implementation of operating procedures. When operating, wear insulated shoes, do not wipe electrical equipment with your hands and a damp cloth, and do not hang clothes on the wires.
In the event of an electrical fire in the event of an electrical fire, it must be quickly opened and extinguished. It is not possible to use water-sparing fire-fighting methods before electricity is cut off to prevent electricity transmission and electricity leakage. If someone gets an electric shock, cut off the power immediately and save someone. If the knife is far away from the electric shock, use an insulator such as a wooden rod to remove the electric wire. Do not pull the electric shocker by hand. Otherwise, the tractor will also get an electric shock.
