Measures for low vacuum pumping efficiency of trolley annealing furnaces

At present, based on production practice, there are various factors that contribute to the low vacuum pumping efficiency of the trolley annealing furnace. By analyzing the factors that cause the low efficiency of vacuum pumping in the annealing furnace, combined with production practice and maintenance labor results, increasing repair cycles, and effectively increasing equipment operation efficiency and productivity, the following effective mechanisms and measures are adopted:
1, Vibration reduction treatment for the trolley annealing furnace:
In order to reduce or remove sealing problems, equipment should be inspected irregularly, and specific treatments should be given to rotary vane pumps and booster pumps. Steel plates or gaskets should be added according to the actual situation. Adding gaskets can greatly improve the defect of bolt loosening and weakened sealing caused by vibration during the operation of the unit. Strengthening the support of steel plates can increase the anti vibration performance of the equipment.
2, Strengthen the management of oil products in annealing furnaces:
We should strictly control the oil used in the trolley annealing furnace, strive to achieve comprehensive monitoring, and timely obtain control feedback. The source of goods is an important link in the initial stage of oil products, and it should be observed thoroughly to directly purchase from the source of oil products as much as possible, in order to avoid counterfeit and shoddy products and ensure stable quality of the source of goods. Based on the proposal of the source of oil products, efforts should be made to gradually unify the oil products.
