Petrochemical bearing forging is an important part in the field of machinery manufacturing, and its selection calculation method is of great significance to the normal operation and service life of the equipment. This paper will introduce the selection calculation method of petrochemical bearing forgings, and illustrate by example.
Selection calculation method
Determine the load type: Select the appropriate bearing type according to the working environment and load type of the equipment. For example, for equipment with heavy loads and high speed, bearings with high carrying capacity and speed should be selected.
Determine the bearing size: According to the working requirements of the equipment and the bearing capacity, determine the bearing size. In general, larger bearings have higher carrying capacity and longer service life.
Determine the bearing accuracy level: select the appropriate bearing accuracy level according to the working accuracy requirements of the equipment. Generally speaking, the higher accuracy level can ensure the stability and accuracy of the equipment.
Determine the lubrication method: according to the working environment and lubrication needs of the equipment, choose the appropriate lubrication method. For example, for high temperature and heavy duty working environments, lubricants with good lubrication performance should be selected.
Suppose there is a high speed mixer for conveying materials, which has a high speed and a strong carrying capacity. In order to ensure the normal operation and service life of the equipment, selection calculation is required.
Determine the load type: Because the equipment needs to mix materials at high speed, its load type is heavy and high speed.
Determine the bearing size: according to the working requirements of the equipment and the bearing capacity, select the bearing with a diameter of 80mm and a length of 120mm.
Determine the bearing accuracy level: Because the equipment has high requirements for working accuracy, the bearing with the accuracy level of P5 is selected.
Determine the lubrication method: Because the working environment of the equipment is harsh, the lubricating oil with good lubricating performance is selected for lubrication.
Through the above example demonstration, we can see that the selection calculation method of petrochemical bearing forgings needs to consider a number of factors, including load type, bearing size, accuracy grade and lubrication method. In the selection process, it is necessary to make comprehensive consideration according to the actual situation to ensure the normal operation and service life of the equipment. At the same time, through a reasonable selection calculation method, the failure rate of the equipment can be effectively reduced, and the operating efficiency and service life of the equipment can be improved.
