Introduction of crane lubrication and maintenance! As a large-scale special mechanical equipment, cranes are operated frequently due to heavy load, and the lubrication and maintenance of cranes must be done well. Now let's talk about the types of crane lubricants, the significance of crane lubrication and maintenance, the basic requirements of crane lubrication and maintenance, crane lubrication and maintenance methods, and crane lubrication and maintenance considerations.
1. Type of crane lubricant:
There are two kinds of lubricants and greases commonly used for crane lubricants;
Crane lubricating oil uses the most liquid lubricant, and the commonly used lubricating oil for cranes is mechanical oil, gear oil, cylinder oil, etc.
Crane grease is a gel-like lubricating material, grease is butter, dry oil. Second, the significance of crane lubrication and maintenance: Doing a good job of crane lubrication and maintenance can give full play to the crane's efficiency, improve productivity, ensure that the crane in production will not fail, reduce maintenance costs and lost work losses. The crane lubrication is an important part of crane maintenance and use.
2. Basic requirements for crane lubrication:
Crane lubrication is one of the important contents of crane maintenance work. The quality of crane lubrication directly affects the operation of various agencies and the life of machine parts, and also affects safety production and production efficiency. Therefore, crane operators and crane maintenance personnel must always check the lubrication of the crane lubrication points, and replenish and replace lubricants on time.
The principles for crane lubrication and maintenance should be followed: all parts with shaft and hole dynamic coordination, and mechanical parts with friction surfaces must be lubricated regularly. Due to the different operating conditions of the crane (utilization rate and use environment, etc.), lubrication of different parts , Should be properly controlled according to the specific situation. Four, crane lubrication and maintenance methods:
The lubrication method of crane operating mechanism is divided into distributed lubrication and centralized lubrication.
Most small and medium cranes use decentralized lubrication. When lubricating the crane, use an oil gun or oil cup to fill the lubrication points separately. Heavy-duty cranes and European cranes mostly use centralized lubrication. There are two types of centralized lubrication: manual pumping and electric pumps. V. Notes on crane lubrication:
1. Keep the crane lubricant clean during use. Check carefully before use. Do not use when impurities or stolen goods are found. 2. Always carefully check the sealing state and grease transfer of the lubrication system and various parts.
3. Lubrication points with higher temperature should increase the number of lubrication and install temperature isolation or cooling devices. 4. The rotating parts of each mechanism without oil injection point should be used to add oil to each rotating gap with oiling tools as necessary to reduce wear and prevent rust.
5. It is not advisable to use resistant base grease in humid places, because of its strong water absorption, it is easy to fail. 6. The pressure injection method should be used to ensure that the lubricant enters the friction surface. If the oil is not condensed, the dilution method can be used to dredge.
