Arts and oil heating systems according to the characteristics of energy boilers, circulating pumps commonly used in addition to the technical performance of the pump outside the arts dual boilers and gas boilers 600 000, from the configuration and performance should meet the following requirements. A circulating pump flow, head and power, should match the fuel consumption and pressure drop requirements for heating systems. 2 oil furnace heating system should be equipped with two separate and have their own power source circulating pump, a re-use a spare. 3 circulation pump should be located at the entrance to the coarse filter, where the HTF must be pumped through the filter to filter out impurities and foreign matter in the heating system should be installed in charge of the road on the way fine filter, filter carbon suspended in HTF grain and high polymers. 4 circulating pump hard reliable sealing to prevent leaks, leaks are found, you should listen to immediately pump inspection and repair. 5 circulating pump cavitation margin should be less than the circulatory system devices NPSH, in order to avoid the occurrence of cavitation pump operation. 6 circulation pump should HTF temperature characteristics adapt warming should be gradual, in front of the high temperature operation of the system should be adopted for the gradual warming of thermal oil pump preheating; In addition, the use should also be noted that not at high temperatures before the pump stops when the pump stops, the system stops working when the arts and gas boilers 1 million dual-boiler, you should wait HTF temperature drops below 100, when the pump longer disabled, should put the net in the HTF pump, and check them regularly test Arts dual boilers and gas boilers 200,000, 180 ° rotation of the rotor regularly during shutdown boiler heating surface surface absorbs moisture from the air to form water film. Water film in the chemical reaction of oxygen and iron rust is generated, the boiler from corrosion. After being put into operation boiler corrosion, rust at high temperatures will increase the depth of corrosion and corrosion area expanded, and iron oxide skin peeling constantly until the bleeding dew that shorten the useful life of the boiler, or even serious explosion. Boiler shutdown maintenance work is to try to reduce air pot of water leakage into the outside world and prevent oxygen, or an attempt to reduce the oxygen in contact with the boiler pressure parts, so that the boiler pressure parts to avoid corrosion or mitigate corrosion. Thermal maintenance methods, wet maintenance, dry maintenance. Thermal shutdown maintenance suitable for hot spare; suitable for short-term maintenance of wet deactivation small boilers; dry law applies to any type of long-term disabled boiler. Current maintenance in wet and dry most widely arts dual boilers and gas boilers 1 million _ _ Arts Arts boiler boiler boiler by Hebei Arts LLC.
