1. The management of fuel should use different grades of diesel according to different ambient temperature (see Table 1); diesel can not be mixed with impurities, ash and water, otherwise it will make the fuel pump premature wear; the content of paraffin and sulfur in inferior fuel High, it will cause damage to the engine; After the daily operation, the fuel tank should be filled with fuel to prevent water droplets from forming on the inner wall of the tank. Before the daily operation, open the drain valve at the bottom of the fuel tank to release water. After the engine runs out of fuel or replaces the filter element, it must be discharged. Despite the air in the road.
Minimum ambient temperature 0°C -10°C -20°C -30°C Diesel grades 0#, 10#, 20#, 35#.
2. Other oil management Other oils include engine oil, hydraulic oil, gear oil, etc.; different brands and different grades of oil cannot be mixed; different types of digging machine oil add chemical effect in the production process or Physical additives are different; to ensure the use of oil cleaning, to prevent debris (water, dust, granules, etc.) mixed in; according to the ambient temperature and use of oil number. High ambient temperature, should choose the viscosity of the engine oil, low ambient temperature should use the viscosity of the oil; gear oil viscosity is relatively large, to accommodate the larger transmission load, hydraulic oil viscosity is relatively small to reduce the liquid flow resistance.
3. Lubricant management uses grease (butter) to reduce wear on the moving surface and prevent noise. When storing and storing grease, do not mix in dust, sand, water and other impurities; it is recommended to use lithium-based grease g2-l1, which has good anti-wear properties and is suitable for heavy-duty working conditions; when filling, try to squeeze all the old oil. Out and wipe clean to prevent sand from adhering.
4. Maintenance of filter element The filter element plays the role of filtering oil or impurities in the gas path to prevent it from invading the system and causing failure; various filter elements should be replaced regularly according to the requirements of the (operation and maintenance manual); when replacing the filter element, check whether it is There is metal attached to the old filter element. If metal particles are found, diagnose and take corrective measures in time; use a genuine filter that meets the specifications of the machine. The filter capacity of the inferior filter element is poor, and the quality of each layer and the material of the filter layer do not meet the requirements, which will seriously affect the normal use of the digging machine.
A laboratory centrifuge is a piece of equipment used to separate components of a mixture based on their density and size. It works by spinning samples at high speeds, which creates a centrifugal force that causes the heavier components to move to the bottom of the tube or container. The lighter components remain at the top or in the supernatant.
Laboratory centrifuges are used in various fields such as biology, chemistry, and medicine. They can be used for DNA extraction, protein purification, cell separation, and blood analysis. They are essential tools in research and diagnostic laboratories.
