Programmable controller in the application of the condensate pump

The high-rise buildings in various cities everywhere. In order to prevent accidental fire, high-rise buildings generally have special fire pump group. Despite the norms, rules and clear fire control facilities, equipment should be regular maintenance. But the condensate pump can do trial run on a regular basis, over time will lead to the pump body, bottom valve and check valve jammed, rust, so often appear in the fire equipment cannot give full play to the role of the situation, there should be no damage, for the civil building water fire extinguishing system design regulation rules supertall buildings, a kind of high-rise public building appropriate when setting the introspection of the condensate pump device. State administration of fire control in the 1999 requires that all fire fighting equipment must be below has self-checking function, fire control equipment must be started automatically in 15 days time, to prevent rust corrosion of pump. Another in the revised "code for fire protection design of buildings are also put forward: fire water supply equipment must have the function of automatic inspection. Usually old equipment adopts behind the relay contactor control method, there is too much intermediate relay and time relay, less functional, line is complex, contact, breakdowns and many poor reliability, maintenance difficulties. We adopt dean kay automation technology co., LTD., Beijing programmable controller (PLC) to control fire pump group, implement regular commissioning when the standby pump group, start automatically when the fire fighting and rescue work, can not be used to effectively put an end to the critical moment of the condensate pump. PLC has the vitality, is its input and output end closer to the field device, does not need to add too much in the middle of the component or need more interface, high reliability, strong ability to resist various kinds of interference, easy maintenance, hardware without adjusting components, low prices long service life. This saves the user time and cost, and can be easily extended to meet the need of different.
