In terms of vacuum pumps, they are essentially a suction device that provides mechanical, chemical, or physical-chemical methods to our vacuum containers, enabling the acquisition of vacuum through various devices or equipment. For vacuum pumps, they are essentially a device that improves a closed space in various ways, or a device that generates and maintains a vacuum. Notes for using Edwards vacuum pumps:

Prior to normal transmission, the vacuum pump should undergo a test to check for any abnormal vibration and impact noises. For vacuum pumps used for the first time, the ultimate pressure of the pump should be determined and should comply with technical specifications. Under long-term working conditions, the temperature of the vacuum pump should not exceed 70 degrees. The measurement of the dry pump's speed. Drying is complex and usually not checked.

Vacuum pumps require cooling water. Before starting, the cooling water should be turned on first. The outlet temperature of the cooling water should not exceed 30 degrees. Thirdly, the pipes of continuous vacuum pumps and conveying systems should be as short and thick as possible. The inner diameter of the pipes should typically not be smaller than the vacuum pump's inlet diameter to avoid the impact of dry pipe resistance on the suction rate.

To maintain a clean and hygienic workspace and promote the health of those sensitive to moisture, please direct exhaust gases outdoors using a flexible hose.

When a vacuum pump has been inactive for an extended period or the ambient temperature is low, it may experience difficulty starting. In this case, the pump's intake should be vented to the atmosphere, and the belt pulley should rotate freely with the wind. The engine oil stored in the oil cavity will drain into the fuel tank, and the pump can then be started. If not, you can use radiant heating or an infrared light to directly heat the vacuum pump until it can be moved.

Before use, check if the engine oil in the vacuum pump has reached the window oil level line. Additionally, it is mandatory to inspect the rotation direction of the motor pulley. The observer should face the pulley, which should rotate clockwise. If the rotation is in the opposite direction, any two-phase connectors in the phase power can be swapped. Otherwise, the scroll vacuum pump will not be able to pump air; instead, it will introduce oil mist from the vacuum pump into the pumping system, causing severe contamination.

Upon completion of the task, first close the high vacuum valve, followed by the low vacuum valve. Then, shut off the scroll vacuum pump and release the air (if using an electromagnetic vacuum release valve, it can be automatically released), to prevent oil from flowing back into the vacuum system. Finally, disconnect the main power and shut off the water.

Be mindful to prevent hard materials (metal shavings, glass shards, etc.) from falling into the vacuum pump, which could scratch its moving parts. When the vacuum pump is not in use for an extended period, store it in a dry, clean environment and seal the exhaust port to prevent dust from entering.

During disassembly, cleaning, and reassembly of the vacuum pump, attention must be given to not damaging the sealing surface, not losing any screws, and ensuring parts are dry or clean and dry. Blow dry or supply dry. As much as possible, eliminate blind spots and adjust the oil quantity to the oil pipeline, avoiding overfilling.
