Two complex issues related to bearing maintenance technology is: When oil change and how much oil should be changed. If too little oil change, the bearings will be early retirement; if too much oil change, the bearings will be in trouble or long-term hazard power coil and wire.

Traditionally, the lubrication plan is based on the time given. Equipment suppliers often lubricated plan to develop according to the operating time. Also, the equipment supplier for the amount of lubricating oil is often added to the guidance in their service planning process. For the staff, the short-term replacement of oil is a very common thing, but often add grease ones. For example, employers are required every two to three weeks change the oil every time you add one ounce of grease. These recommendations led to the outset that they are set up on a number of factors that do not have any real meaning do not know.

Lubrication time interval has a simple premise: to maintain reasonable operation of the device at the bearing not collapse due to drying and stopped conditions. This is a fixed concept of prevention. However, we must maintain a balance and a lot of hungry lubrication between excessive lubrication.
In order to achieve the goal of equipment optimization, we'd know when to stop and when to lubricate the bearing refueling. Based on criteria developed by the lubrication policy can achieve this goal. Simply put, bearing conditions determine when an oil change. When the bearings run smoothly and there is no indication that the bearing changes, lubrication should be avoided, the normal operation of it; if conditions change or the need for lubricating bearings shows, then you should use lubricants. Detecting bearings, oil change can help us decide the amount of lubrication as well as when to stop adding oil.

Ultrasound technology is ideal lubrication under conditions effective manner. I want to understand why, we must understand the ultrasound technology, how how the bearings ultrasound, and ultrasound testing equipment is helping us maintain optimum lubrication strength in the bearing.
Ultrasound technology is based on high-frequency sound sensor to measure. Ultrasonic turn 20,000 laps per minute or 20,000 Hertz. Taking into account the ultrasonic frequency when people stop high-frequency hearing has just begun. Most of the ultrasonic instrument can sense 20KHZ to 100KHZ. And people's hearing range, but only from 20HZ to 20KHZ. Highest average people often hear 16.5KHZ or some more.
