A boiler installation units must comply with the standards promulgated by the state, reference GB50273 "industrial boiler installation construction and acceptance of universal norms" were. 2 should be read before the installation and use of this manual and electric control system schematic carefully. 3 Note: ① boiler installation site must have 380/50 (V / HZ), enough power capacity, operation and maintenance of adequate space (less than both the front and rear end 1.2m).. . ② boiler installation site should be dry and ventilated boiler arts, meet fire condition; not near flammable and explosive materials; prohibit the installation in damp, open-air and acid, alkali and other corrosive places. ③. Boiler installation site must not have hypertension power interference sources, so as not to cause the control system malfunction. ④. Boiler installation must comply with load-bearing conditions, if installed on the building must seek permission from the construction sector. ⑤. Pumps, valves, tanks, piping installation must meet the requirements of GB / 50041's. ⑥. Boiler power line should have sufficient cross section. (Minimum cross-sectional area to see electric wiring diagram) ⑦. Boilers and boiler electrical control box enclosure should be grounded. Grounding resistance should be less than 4Ω. 3 boiler foundation: ground dust after compaction, watering flat concrete foundation thickness is determined by the design of the unit according to user units soil conditions. Arts boiler shutdown period 200,000 oil and gas dual-energy boiler thermal oil heaters, 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 arts 600,000 oil and gas boilers dual oil furnace, rust at high temperatures will increase the depth of corrosion and corrosion area expanded arts and gas boiler 800,000 dual oil furnace and continuous oxide skin peeling until of leakage, resulting in shortening the 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 100,000 oil and gas boilers dual oil furnace | Arts boiler | boiler provided by the Hebei Arts Arts boiler limited liability company. Hebei Arts boiler limited liability company (www.yi-neng.cn) strong, credible, Cangzhou in Hebei industrial boilers and accessories industry has accumulated a large number of loyal customers.
