Analysis of daily maintenance of vacuum pump

In the vacuum laser collimation system, the CCD imaging system is mainly composed of an industrial control computer, an image card, a control box, and a dedicated data acquisition application software. The image card converts the video signal transmitted from the CCD coordinate system into a digital signal for processing by a dedicated image analysis software to obtain the displacement of each measurement point. The orderly operation of each part of the control system: Turn on the laser power, turn on the cooling water pump at regular time, start the vacuum pump, turn off the vacuum pump, turn off the cooling water pump, then control the measuring points in turn, process the obtained observation data, and connect to the monitoring center through the optical cable. Saved to the server's database and timely display and printouts.

Vacuum equipment is mainly composed of vacuum piping, flat crystal, stainless bellows (used to compensate for the thermal expansion and contraction of vacuum piping, Ningbo air compressor to reduce the thermal stress on the measuring point), vacuum pump, and vacuum table (for labor Measuring the vacuum degree of the vacuum pipe) and other five parts.

The CCD converts the acquired timely image into a video signal and transmits it to a computer. The PCI image card converts the signal to a digital signal. The image analysis software then processes the image to obtain the energy center of the spot, which is the spot coordinate of the spot, and then passes the dedicated application program. Processing can calculate the displacement of the corresponding measuring point.

The daily need to pay attention to vacuum pump maintenance, maintenance items include regular replacement of the vacuum pump oil, check the system vacuum, remove the air in the vacuum pump, check the vacuum pump belt running conditions (discovery aging, timely replacement). Normally, the vacuum pump should be manually operated once a month to check the operation status of the vacuum pump and the cooling system, and the vacuum degree of the system can be checked through the Maxwell vacuum gauge.
