真空泵作为水厂中主要的附属设备,广泛地应用于水厂进出水泵房中。本文结合闸北水厂近几年的改造过程中所涉及的水环真空泵及在线式真空泵的生产应用,设计了一种融合上述两种真空泵的优点的离线式真空泵,同时该系统充分考虑了电能的计量及与厂内原有PLC系统的兼容。该套系统在实际使用中效果显著,确保了厂内泵房的自动化运行,同时有效地降低了操作的劳动强度。 As the main auxiliary equipment in the waterworks, vacuum pumps are widely used in waterworks in and out of pump houses. In this paper, we combine the production and application of water ring vacuum pump and on-line vacuum pump involved in the process of reconstruction of Zhabei Water Plant in recent years, we design an offline vacuum pump that combines the advantages of the two vacuum pumps. At the same time, Measurement and compatibility with the original PLC system in the factory. This set of system is effective in actual use, ensuring the automatic operation of the pumping station in the plant and effectively reducing the labor intensity of the operation.
