First, the environmental conditions of the bearing warehouse /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
Room temperature <br> The room temperature of the storage rolling bearing warehouse should be air-conditioning or water-tight; the control is in the range of 5 ~ 25 °C.
The room temperature is too low; the anti-rust oil will harden and crack; the harmful substances such as moisture will be rusted by the crack directly touching the bearing surface; the room temperature is too high; the anti-rust oil will melt; the effect on the bearing appearance is lost; day and night The temperature difference is too large or the temperature is too large; the moisture in the atmosphere will condense into water droplets on the bearing surface; then the bearing corrosion will be incurred.
If there is no air conditioning condition; when the temperature is lower than 5 °C, the far-infrared electric furnace should be used for indoor heating; it is not suitable to use coal, wood, oil and other types of fuel to heat; because this will generate harmful gas; cause bearing corrosion. It is also possible to use a closed fireplace or stove; use a well-sealed flue and high smoke; discharge the incineration into the outdoor.
The number and distribution of heating equipment should be based on ensuring that the temperature at the bearing storage can be increased more evenly. Above 25 °C; the best use of natural convection to cool down; prevent the use of forced dust that is easy to raise dust or bring moisture Air-cooling method; if it is necessary to use electric fans; it is advisable to use a louver-type electric fan with high equipment orientation; the number of electric fans and the selection criteria for the distribution should be such that the indoor storage bearing is cooled as uniformly as possible; the airflow has no vortex and no dead angle. .
Avoid blowing air on the bearings; pay special attention to the entrances where the portal is often open; because of the high temperature of the bearings, the cool breeze will also condense the water droplets; this should also be paid attention when swapping the room air in the morning.
Warehouse humidity <br> The warehouse where the bearings are stored; the indoor relative humidity should be kept at 45%~60%; beyond this limit; the dehumidification method should be adopted. The dehumidification equipment should be set at the inlet end of the air duct; Absorbent substances such as silica gel. Excessive humidity; easy to cause corrosion of bearings; shorten the "stock life" of the bearing inventory safety period; rainy days to prevent raincoats, wet shoes, etc. into the room.
Indoor air conditions <br> The warehouse where the bearings are stored; the indoor air should be clean; dust-free; dull; no acid gas; water vapor or other corrosive gases; the best temperature is also properly adjusted. Use gauze dustproof.
Indoor environment <br> The best place to store bearings in the warehouse. If it is necessary to store a room with other items; the items stored together are absolutely not so acid, alkali, salt or other chemicals; let alone touch with these items. Items that are stored together need to be clean and dust-free; the nature is stable; no moldy changes or release of harmful gases. Even if the items meet the conditions; also separate from the bearing; avoid causing disorder.
Location of the warehouse <br> The orientation of the warehouse for the registered bearings should be chosen in a quiet place; in an environmental sanitation place; it is not in a disadvantageous position of harmful atmospheric sources or dust and dirt sources throughout the year; especially away from chemical warehouses, heat treatment or pickling workshops, foundry workshops and Forging workshop; even the mill workshop. The gate of the warehouse is not suitable for the south.
The shelf of the second bearing <br> The shelf of the bearing; the table top should be flat without convex and concave; there must be no nail head or burr; the frame body can ensure the necessary strength and rigidity; it can be made into a truss type for ventilation; The minimum storage orientation of the bearing should be more than 0.33m above the ground. The shelf top should be padded with non-corrosive moisture-proof oil paper; the bearing has a certain maximum density; it can not hinder the ventilation of other bearings.
Large bearings should be placed adjacent to suitable lifting equipment; and corresponding transport vehicles are available.
The fine bearing should be stored in a special temperature-controlled dehumidification chamber or cabinet for storage; the ambient temperature is maintained within the range of 5-15 °C throughout the year; the residual austenite in the bearing is controlled to be durable; the dimensional accuracy of the bearing is adhered to.
The above conditions are indeed unreachable; at least the fine bearings should be placed in the most stable position of the indoor temperature.
Where conditions permit; the bearing's loan frame can be depicted as a rotary and lift type; or depict active pick-up equipment.
Third, the indoor layout of the warehouse <br> The warehouse of the storage bearing should have a moisture-proof floor; the wall construction materials should be stabilized and neutral; the unstable chloride wall cloth can be used to form a coating with evaporation; the wall should be flat and lubricated; Do not block the airflow; collect dust. Sunlight from the doors and windows; not directly durable on the bearings.
