Roots fans that are operated or stored for a long time will inevitably be covered with dust! And too thick dust will affect the heat dissipation of Roots blower! In high temperature weather in summer, it often causes the problem that roots blower can not operate normally. It can also be said that the high temperature of Roots blower in summer may be caused by too thick dust, which hinders the normal heat dissipation of Roots blower. Therefore, the cleaning of Roots blower is often an important work of daily maintenance! Today, roots blower manufacturer Shanghai Ruizhe environmental protection will analyze for you what kind of cleaning roots blower uses? What principles should different parts follow.
1. Cleaning supplies.
Prepare cleaning tools and detergent before cleaning. Cleaning tools include oil pan, oil bucket, cotton yarn, cloth head, emery cloth, oil, brush, bamboo or wood scraper, etc. Cleaning agents include solvent oils (such as kerosene and gasoline), organic solvents (such as banana water and alcohol), alkaline solutions and various metal cleaning agents.
The selection of cleaning agent should adapt to the material characteristics of parts. For example, solvent oil can remove ordinary oils, whether cast iron, steel or non-ferrous metals. However, the oil seal and O-ring should not be cleaned, otherwise the colloid will expand and deform. In addition, leaded fuel gasoline has corrosive effect on metals and is harmful to human body, so it should not be used as a detergent.
2. Cleaning method.
After disassembling various parts, there are mainly the following two situations: oil and ash stains on the surface of parts, and rust layers on the surface of metal parts. The cleaning methods are different.
(1) Remove rust.
Generally speaking, the severely corroded parts can be polished with coarse sandpaper, and the slightly corroded surfaces can be polished with fine sandpaper (or fine oilstone) and lubricating oil. If the floating rust is too thick, it can be removed by scraping, or wet the corroded part with kerosene first, and then brush the steel wire brush with talc powder repeatedly. Suitable derusting solution can also be selected according to the nature of rust turbidity.
According to the quality requirements, slight rust spots should be completely removed to make the rust surface show the original metallic luster; The medium rust layer shall be removed until the surface is smooth, and the markings and cloud marks are allowed; Heavy rust should be removed, but there are black spots in the pit. Polish carefully and appropriately, especially the mating surface of shaft and bearing, shaft and gear, and try to ensure its smoothness and fitting accuracy. After rust removal, clean Qin with kerosene or gasoline, and apply antirust oil after drying.
(2) Clean the oil dirt.
Due to the deterioration of the old oil or the adhesion of dirt, some parts have thick oil dirt on the surface. In this regard, first use a wooden scraper to scrape the oil sludge from Qin Shang, and then clean it with detergent.
Small metal parts can be put into an oil basin containing solvent oil or banana water. When part C is large and cannot be contained in the oil basin, you can first wipe the oil stain with old cotton yarn, and then wipe the greasy part with clean cotton yarn (or cotton cloth) dipped in solvent oil or banana water until the clean sewage bottoms out. If the oil sludge is thick, soak the parts in kerosene for a period of time (generally 10~30min), and then brush after most of the oil dirt is dissolved. After cleaning with solvent oil or banana water, the surface of parts can generally be dried by itself.
When cleaning parts with alkaline solution, a special sink or washing machine is required. When cleaning with soaking tank, first heat the cleaning solution in the tank to above 80 ℃, then soak the metal parts to be cleaned in the tank, supplemented by mixing. After soaking, wash with hot water (water temperature 50-70 ℃) and cold water to remove the residues on the surface of the parts, and finally dry the surface with hot compressed air to prevent rust.
In addition, for non-metallic parts such as rubber parts and plexiglass oil labels, do not use alkaline solution. You can wipe the gauze with alcohol to make the oil stick to the gauze, and then clean the gauze with alcohol. In this way, repeated wiping can wipe off the oil stain.
3. Cleaning requirements.
(1) When cleaning the rolling bearing, do not rotate too early to avoid the dirt in the bearing scratching the rolling body and raceway. Do not use cotton yarn, but clean it with clean cotton cloth to prevent the yarn head from winding in the bearing.
(2) When cleaning the oil tank, first remove the debris, dust and oil deposited on the bottom of the tank, and then apply light color paint on the inner wall of the tank.
(3) For non-metallic parts, the temperature of the cleaning agent should not be too high (preferably room temperature) to prevent the parts from becoming soft and deformed.
(4) After cleaning with plexiglass oil, grind and polish it if necessary to restore its transparency.
(5) For important parts such as gears, bearings and shafts, if they are not assembled immediately after cleaning, they should be coated with antirust oil and cleaned after assembly.
(6) Before assembly, the antirust oil and dust on the surface should be cleaned.
