Dry vacuum pump lubrication and open pump note _

1, the dry vacuum pump under normal work in the standard all speed than 20000 hour or up to three years later, should eliminate the rolling bearing and note within the interior space waste vegetable oil and dirt and fill the new plant oils.

2, for the dry vacuum pump to fill the plant oils and fats should make up 50% of the rolling bearing free space and rolling bearing cover 65% of the interior space.

3, if the dry vacuum pump work in the standard is very extreme, the lubrication oil conversion cycle time to be relatively reduced.

the dry vacuum pump for lubrication maintenance is one of the key processes, grasp the proper lubrication method, is beneficial to the application of machinery and equipment.

1, determine the pump motor is closing, the dry vacuum pump with the criteria, contact the relevant position operator, to determine the pump does not turn, barring symmetrical flexible, open water pump valve open a third valve position, starting motor, will immediately after starting motor pump shell water online gate valve, sealing liquid valve opens, prompting more than of the water in the pump casing and gas water separator equilibrium, but guys, if appear the following status immediately stop pump: abnormal leakage, abnormal vibration, abnormal noise, odor, fire, smoke, electrical flow continuously come down.

2, adjust the import and export trade of pump valve, vacuum pump channel value in 0. 08 - 0. 02 mpa, inward and outward normal traffic, electric mechanical and electrical flow in the range of normal, adjust pump total flow, contact the relevant position operator, determine the pump working pressure steady import and export trade.

usually under the condition of dry vacuum pump is prohibited without high speed liquid, in case of damaged parts, when import vacuum pumps to open. In the entrance valve open conditions, long-term operation is prohibited.
