In order to reduce the agricultural production expenditure, the “machine†households are introduced here to introduce the general knowledge of agricultural tractor oil selection. It is believed that this will help the “machinery†households.
First, the choice of diesel
Diesel oil has the distinction between light and heavy diesel oil. Agricultural tractors generally use light diesel oil. Light diesel oil is generally divided into 10, 0, -10, -20, -35, etc. according to its condensation point. In order to save expenses, in addition to the need to prepare oil No. 35 for raising machinery for transportation in winter, most of the regions in Jilin Province are generally engaged in agricultural production. Only diesel oils Nos. 0 and -20 can be provided. Diesel No. 0 is used in summer and No. 11 diesel is used in winter. In other regions, the appropriate number of diesel can be selected based on the specific local temperature conditions.
Second, the choice of oil
Agricultural diesel engines need diesel engine oil. Diesel engine oil is divided into No.8, No.11 and No.14. It is generally used No. 8 oil in summer and No. 11 oil in winter.
Third, the choice of gear oil
Gear oil is divided into 20 and 309. Use No. 30 for summer and No. 20 for winter. Here to remind the health care households to pay attention to the drug is strictly prohibited to use oil instead of gear oil, or in the gear oil blended with diesel and kerosene, so as not to reduce its viscosity, reduce lubrication performance, accelerate gear wear.
Fourth, the choice of butter
The choice of butter for diesel engines is not "one size fits all" and must be targeted according to the various components of the diesel engine:
1. Parts that are in direct contact with water or moisture and have a lower operating temperature may use calcium base grease or synthetic calcium base grease.
2. The components with high working temperature can use calcium-based fat to synthesize calcium grease.
3. Parts that do not come in contact with water or moisture and have high temperatures can use sodium grease or synthetic sodium grease.
4. When the temperature is high, the operating temperature is high and the load is large, the grease with higher grade should be used.
5. In general, butter with high grade is used in summer; butter with low grade is used in winter.
A key doorknob lock. This is a simple doorknob that includes an internal lock that is operated by inserting a key into the lock component. Turning the key makes it possible to lock and unlock the door, effectively limited access to the building to those who have keys that fit the lock. Different surface treatments are acceptable.
