Shaking bag desulfurization
The Sulfur Removal Method with Rock Bags
Rock bag desulfurization (RBD), also known as scrubber desulfurization, is a cost-effective method to remove sulfur emissions. The method can be applied to dozens and hundreds of smokestacks, and is widely used in many countries. Rock bag desulfurization s......
Flotation column
Floatation Columns
Floatation columns are large pieces of industrial equipment that are used in various manufacturing processes. They are designed to provide a stable medium for the removal of a specific material from a liquid or solid mixture. Floatation columns are made up of a vessel with an a......
The solution of the pump bearing seal is not resistant to wear and high temperature
Solution for Wear and High Temperature Resistance of Pump Shaft Bearing Seals
The pump shaft bearing seals are necessary components of pumps and are used for the isolation of interior pumps from exterior environment and for the backflow of liquid between the pumps, which is significant for the n......
Purpose and method of bearing lubrication
Purpose and Methods of Bearing Lubrication
Lubrication is an important way to reduce the wear of bearing and increase the service life of bearing. The purpose of bearing lubrication is to form a certain oil film between the relative moving parts, so that the relative motion between the moving par......
Lubrication and sealing of rolling mill bearings
Rolling Bearings Lubrication and Sealing
Rolling bearings have been in use since the late 19th century to provide long-lasting and reliable performance in heavy-duty machines. Although they have evolved and become more sophisticated over time, the basics of lubrication and sealing remain the same......
Application of Special Engineering Plastics in Bearings
Application of Special Engineering Plastics in Bearing
Bearings are vital components of mechanical equipment. They are widely used in the transmission of rotary and linear motions of equipment, and can be roughly divided into rolling bearings and plain bearings. In increasingly complex and harsh ......
Definition and Application of Abrasion Resistance
Wear is a form of mechanical damage that occurs when two objects in relative motion come into contact and interact with each other and a tribological, or friction-induced, force is applied. Wear is one of the more common forms of mechanical damage, and it can come in many different forms such as a......
How to improve the BONDING ability of electroplating
Improving Bonding Ability of Plating
The electroplating layer provides strong adhesion to the substrate and imparts corrosion resistance, wear resistance, solderability, and many other desirable properties for the treated part. Plated coatings are particularly suited for decorative finishes since......
