Sodium sulfide leaching
Sodium sulfide leaching
Sodium sulfide leaching is considered to be a kind of leaching method mainly applicable to oxidized gold-bearing ores. The advantages of using sodium sulfide for gold leaching are that the reaction rate is rapid, the corrosion of equipment is reduced, and the formation of g......
carbon disulfide poisoning
Carbon Monoxide Poisoning
Carbon monoxide (CO) poisoning is a preventable but potentially fatal condition caused by exposure to high levels of the colorless, odorless, and tasteless gas. Carbon monoxide poisoning is a serious issue, annually resulting in over 500 deaths in the United States, and ......
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......
Proper lubrication of cross shaft universal joints
Introduction
A universal joint (U-joint) is an essential component of many machines and is used in mechanical drives and automotive components to transfer power from one shaft to another while allowing the two shafts to be at different angles. The U-joint allows for varying angles of rotation bet......
Grease lubrication of bearings in wet environments
Grease Lubrication of Bearings in a Humid Environment
Bearing life is one of the key challenges facing machinery designers, and lubrication is a critical part of bearing life. Grease is simply oil thickened with a thickener to produce a stable mass. It is often blended with additives, such as ext......
Solid Lubricated Bearings
Solid Lubricant Bearings
Solid lubricant bearings reduce friction and increase system uptime under extreme temperature and load conditions. Solid lubricant bearings, also known as self-lubricating bearings, are used in a variety of applications that experience extreme temperatures or loads, such ......
