What oil is used to lubricate the slurry pump?
Published:
Oct 08,2024
What oil is used to lubricate slurry pumps is one of the concerns of customers and is also a maintenance issue that needs to be understood during the use of slurry pumps. The part of the slurry pump that requires lubrication is the bearing rotor. However, different slurry pumps use different lubricating oils. Currently, the lubrication methods for slurry pumps in China are mainly divided into two types: grease lubrication and oil lubrication. It is important to note that regardless of the lubrication method, the lubricant needs to be replaced regularly.

What is grease lubrication?
Grease lubrication is achieved by manually filling grease into the machine casing. This method is mainly used for rolling bearings with a speed not exceeding 3000 revolutions per minute, a temperature not exceeding 115°C, friction pairs with a circumferential speed below 4.5 meters per second, heavily loaded gears, worm gears, chains, steel ropes, etc.
Grease can reduce mechanical friction, prevent metal aging, and prevent gas, oil, and water leakage, ensuring the normal operation of mechanical equipment.
Classification of grease
- Classified by the lubricated mechanical components: bearing grease, gear grease, chain grease, etc.
- Classified by the industrial sectors using the grease: automotive grease, railway grease, steel grease, etc.
- Classified by the temperature of use: low-temperature grease, regular grease, and high-temperature grease, etc.
- Classified by application range: multi-purpose grease, special grease, and general-purpose grease.
- Classified by the thickening agents used: sodium-based grease, calcium-based grease, aluminum-based grease, complex calcium-based grease, lithium-based grease, complex aluminum-based grease, complex barium-based grease, and complex lithium-based grease, bentonite grease, silicone grease, polyurethane grease, etc.
- Classified by base oil: mineral oil grease and synthetic oil grease.
- Classified by load-bearing performance: extreme pressure grease and regular grease.
What is oil lubrication?
Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and machinery to reduce friction and protect machinery and processed parts. Its main functions include lubrication, auxiliary cooling, rust prevention, cleaning, sealing, and buffering.
As long as it is applied between two relatively moving objects and can reduce the friction and wear caused by the contact of the two objects, it is considered lubricating oil.
Lubricating oil and grease are both types of "lubricants." Simply put, a lubricant is something that exists between two relatively moving objects and has the function of reducing friction caused by their contact.
Lubricating oil is a technology-intensive product, a complex mixture of hydrocarbons, and its actual performance is a comprehensive effect of complex physical or chemical changes. The basic performance of lubricating oil includes general physical and chemical properties, special physical and chemical properties, and simulated bench test results.
Each type of lubricating oil and grease has its common general physical and chemical properties to indicate the intrinsic quality of the product.
