The present invention provides an energy-saving and non-stop maintenance control system and method for vacuum pumps. The system includes multiple single crystal furnaces, a main evacuation system, a first centralized evacuation system, a second centralized evacuation system, and multiple first vacuum pipelines. It is connected in parallel to the vacuum pump pipeline of the main evacuation system, and each first vacuum pipeline is equipped with a first-level main ball valve corresponding to each single crystal furnace, and multiple second vacuum pipelines are connected in parallel to the first centralized evacuation system. The vacuum pump pipeline of the system is connected, and a first centralized evacuation ball valve is arranged on each second vacuum pipeline, and multiple third vacuum pipelines are connected in parallel to the vacuum pump pipeline of the second centralized evacuation system, and each third vacuum pipeline is All are equipped with a second centralized evacuation ball valve. The invention can carry out independent maintenance and cleaning at the same time when the stove base is in high-temperature vacuum continuous production state, the utilization rate of the vacuum pump is high, the use effect is good, the maintenance is convenient, the filtering effect is good, and the cleaning is more convenient.
Description
A control system and method for energy-saving and non-stop maintenance of vacuum pump technical field The present invention relates to the technical field of photovoltaic equipment, be specifically related to a kind of energy-saving and can keep the furnace maintenance vacuum pump control A system and a control method using the system. Background technique Today, with the rapid development of photovoltaic technology, solar cells produced by using silicon single crystal can directly convert solar energy into solar cells. Converted into light energy, realizing the beginning of the green energy revolution. Single crystal growth furnace is a single crystal growth equipment, with the photovoltaic technology With the rapid development of technology, the industry has also developed rapidly, and single crystal growth is required to be carried out in vacuum and inert gas. real The empty device should be able to ensure that the thermal vacuum degree in the furnace body is ab...
