RY air-cooled high-temperature heat-conducting oil pump adopts self-heating heat-dissipating structure, which changes the traditional water-cooling structure, which makes the structure simple, small in size, saves operating cost, has good performance and reliable use. It is the foundation developed on the basis of digestion and absorption of foreign oil pumps in China. The second generation of stainless steel "target=_blank> stainless steel heat transfer oil pump bearing damage ten reasons and solutions first, stainless steel "target=_blank> stainless steel heat transfer oil pump bearing overload - overload.
Solution: reduce load or redesign - if the system is constantly overloaded, try to re-select the bearing; system short-term overload and impact load, can try to improve lubrication, bearing specialization and other solutions.
Second, stainless steel "target=_blank> stainless steel heat transfer oil pump bearings withstand too high temperature, overheating - this is performance. Like "fever."
The signs are raceways, ball and cage discoloration, from gold to blue - mild lubricant discoloration, even attached to raceways or rollers. Heavy bearing components are blue in color. Metal flow occurs in heavy bearing components.
Temperatures above 400F anneal the raceway and rolling element material - this is the effect of high temperatures on the mechanical properties of the bearing.
Reduced hardness results in reduced bearing load and early failure - bearing raceway or roller hardness below HRC58 will reduce life.
Solution: The bearing must run with a certain viscosity above the operating viscosity; the temperature rise will reduce the viscosity of the lubricant and even affect its basic chemical properties.
Third, the heat transfer oil pump bearing pseudo-cloth dent - "false Brinell indentation".
The elliptical wear dents produced at each ball position are smooth, have sharp boundaries, and are surrounded by grinding - the shape is not always necessary. Such damage generally has no signs of grinding within the indentation.
Solution: Vibration isolation and the use of anti-friction additives - generally caused by chattering during transportation.
Fourth, the heat transfer oil pump bearing cloth hardness dent - "true Brinell indentation".
Produced when the load exceeds the elastic limit of the raceway - typically caused by radial impact loads.
Dents on the raceway increase vibration (noise)
Solution: Any static overload and severe impact creates a cloth dent - such damage typically remains in the indentation.
Fifth, normal fatigue failure - fatigue damage.
Stainless steel "target=_blank> stainless steel heat transfer oil pump bearing fatigue failure refers to chipping on the raceway and rolling elements, and the resulting material fragments fall off - including fatigue cracking and fatigue spalling.
This fatigue occurs gradually, and once it starts, it expands rapidly, with a noticeable increase in vibration - quenched steel generally expands rapidly and is prone to transient damage. Carburized steel will have a longer development.
Solution: Replace the bearing, and design the bearing with a longer fatigue life - it should be said to use a higher rated dynamic load bearing, higher purity bearing steel and so on.
Sixth, stainless steel "target=_blank> stainless steel heat transfer oil pump reverse load - abnormal load.
Angular contact bearings are designed to accept only axial loads in one direction. When the directions are opposite, the elliptical contact area of ​​the outer ring is flattened. . .
The result is an increase in stress, an increase in temperature, and an increase in vibration and early failure of the bearing. Seventh, internal contamination of the heat transfer oil pump bearing - is said to be foreign matter.
Contamination is one of the main causes of bearing failure. The signs of contamination are a little trace on the surface of the raceway and rolling elements, resulting in increased vibration and wear and tear: clean environment, tools, and specification operations. Storage and transportation of new bearings.
Eighth, the lubricant in the heat transfer oil pump bearing fails - lubrication failure.
The discoloration (blue, brown) of the raceway and rollers of the heat transfer oil pump bearing is a sign of lubrication failure, which in turn causes wear of the raceways, rollers and cages, resulting in overheating and severe failure. Early is a slight glassy flaw on the raceway surface.
The normal operation of rolling bearings depends on the existence of good oil film failure between the parts, often caused by insufficient lubrication and overheating - there may be wrong lubrication (too much lubricant, too little, too silk, too thin) and ineffective lubrication (wrong lubrication) Ways, oil cut, not replaced in time) two reasons.
Ninth, the heat transfer oil pump has long been different - the partial load.
The sign of misalignment is that the wear marks on the raceway are not parallel to the edge of the raceway. If the misalignment exceeds 0.001 in/in, Botaibang will produce abnormal temperature rise of the bearing and the housing, and the cage ball will wear--a different bearing Types have different allowable partial loads. General self-aligning bearings have the best eccentric load capacity. However, other bearings can achieve the purpose of increasing the certain eccentric load capacity by optimizing the raceway geometry.
Tenth, corrosion - a kind of foreign matter entering, water.
The sign is a reddish-brown area on the raceway, roller, cage or other location - early rust, usually black.
The reason is that the bearing is exposed to corrosive fluids and gases. In severe cases, corrosion causes early fatigue failure of the bearing. To eliminate the corrosive fluid, use integral sealed bearings as much as possible. Sealed bearings are not preferred. Each bearing has its sealing system, the key is to make it effective.

The second-generation product, this type of pump is a high-temperature dangerous product, which belongs to the scope of the national production license. Please do not purchase unlicensed products, so as to avoid the danger in the process of use. The authenticity of the production license can be found on the China Technical Supervision website.

Zippered tool bag is a type of tool bag that features a zipper closure, rather than an open top or drawstring closure. The zipper allows for secure and easy access to the contents of the bag, while also providing additional protection for the tools inside.
Zippered tool bags can come in a variety of sizes and materials, ranging from small pouches designed to hold a few small tools to larger bags that can hold multiple tools and accessories. They are often made of durable materials such as nylon or canvas, with reinforced stitching and heavy-duty zippers to withstand the wear and tear of daily use.
Zippered tool bags are popular among professionals and DIY enthusiasts alike, as they provide a convenient way to organize and transport tools without the risk of them falling out or getting lost. They can be easily carried by hand or using a shoulder strap, and some models even feature additional pockets and compartments for storing smaller items or accessories.
