The
self-lubricating bearings of Hunan Jintai Hardware and Machinery Co.,
Ltd. have a wide range of operating temperatures, adequate solid-smooth
data content, uniform release, excellent self-smoothing, and occlusion,
effective maintenance of journals, and long-lasting application intent. Suitable
for operation in high temperature, low speed, heavy load, large dust,
water shower, and shock oscillating environment. It can be widely used
in tumbling of mechanical equipments such as mining machinery,
metallurgy, petroleum, chemical industry, food, textile, papermaking,
printing and dyeing. And sliding bearing parts.
The
aluminum ingot produced from the aluminum electrolytic cell is poured
into a mixing furnace after being sucked and sucked by a vacuum. After
passing through the ratio and de-slag, the aluminum ingot is poured into
an aluminum ingot casting machine to be cast and molded. The formed
solid is called an aluminum ingot. Aluminum ingots are stacked by a stacker. In
order to improve the output power, it is necessary to use a lot of
cooling water for cooling before the aluminum ingot is formed. During
the cooling process, the infinite thermal energy of the aluminum liquid
is released into the cooling water, and a fiery steam occurs. Casting
machine bearings are in a high-temperature Wenshui steam environment,
many of the bearings are grease smooth, increased smooth grease will be
melted overflow due to high temperature in a short time to remove,
maintenance maintenance is difficult, the device is also easy to clean
appearance. In addition, the steel layout bearings are easily corroded and rusted
in a hot and humid environment. The failure rate is very high, equipment
repair costs are high, and the equipment operation is often confused by
the following two problems.
First, the wear
The abnormal wear caused by the two major problems in the bearing operation of aluminum ingot casting equipment is severe. Taking
a company's pulling ingots as an example, the bearing has a uniform
service life of 2 months. When the wear is severe, the 5mm inner ring is
worn out, resulting in the inability of the equipment to continue
working. The
reason is that the original plan to oil method can not be completed,
had to be outside the bearing in the operation of burning thin oil, a
few can be burned into the bearing, the wear is smaller, and beyond 50%
of the shaft and sleeve did not get smooth, in the soil conflict Strong adhesive wear occurs in the case. This wear quickly increases the clearance between the shaft and the
sleeve, so that the dust can enter more easily and constitute a vicious
circle.
Second, the choice of oil-free self-lubricating bearings
In
order to deal with the smooth question of high temperature, low speed,
heavy load, large dust, water showering and impact oscillation in the
mechanical equipment, the oil-free self-smooth bearing is selected.
