Steam and hot water boiler water level gauge fault safe hydraulic machine operating company of Henan fast boiler with small series to introduce a common oil fired 1000kg steam boiler 1 ton boiler in stock water gauge Problem safe operation of steam and hot water boiler water gauge failure of hydraulic machine, the causes and solutions approach a hot water boiler steam water gauge reason and common problems: 1, the water level is too low mounting table; 2, water table, even the water pipe is too small; table 3 have low level or a water level indicator, when active, only one only water table; 4, the ground water table, drain cocks no drainage; 5, a drum water level on the table is valid, another water table damage; 6, the tap water gauge screw fixed; 7, the tap water gauge leak, leaking; 8, the performance of the water table level false; 9, the drum water level in the water table irregularities two inconsistent; water gauge glass often broken; 11, water level gauge glass without guard; 12, water gauge low water level glass plate not shown in the red line instructions; 13, glass plate dirty water table, the water level observation is unclear. The main reason is because of 1-4 above design, installation or alteration of dislocation caused. When the steam boiler with a low water table position when the drum is only a case of the water table, water table because the internal balancer lowland leakage short-circuit (at that time can not be detected), resulting in the emergence of lowland water table high water level ( the so-called full of water), and the water table on the drum performance but low water level (or even probably not see the water level), then the fireman because they can not determine the true level of the boiler will go immediately and check the water level in the drum on the table, it will be very serious water shortage in container delays when the boiler accident occurred. Glass-sided water table in front of a glass sheet metal frame box lined with asbestos pad contact surface made of cardboard and then screw the cover frame and the cover pressure closely. Some even show the water level too low trust status of the water table, and take a little sewage, mistakenly steam boiler water when filled with water incident handling, accelerate the production of the accident, there is precedent for such incidents to be investigated. Then, the above-mentioned reasons hinder 5-9 problem occurs mainly boilers lasting not run when washed in water table, not routine maintenance, resulting in water gauge cocks rust, gas, water and even the block, or insufficient packing or aging deterioration. False water level phenomenon, in addition to gas, water or even the cock pipe is blocked, but also could be vapor, the water pipe connected to the water table caused by misalignment connection; steam, water tap handle installed the wrong position resulting cock closed, since there poor water quality, the boiler priming and thrown false water level. Water gauge glass is broken mainly steam, water faucet centerline not aligned, the presence of glass bending stress; long glass without expansion gap; water table is at the window glass is a cold draft, and the glass pipe quality was poor. Safe operation of hydraulic machine 1, hydraulic machine operator must be trained to master the equipment performance and operating techniques to work independently. 2, before the operation, you should clean up various debris on the mold, wipe any dirt hydraulic rod. 3, the mold must be installed hydraulic machine in case of power failure, and prohibit the collision start button, the lever foot on the footswitch. 4, installed on the upper and lower dies, the die gap adjust, unilateral allowed off-center, a good confirmation of the fixed mold pressure again. 5, before the hydraulic machine is first started working apparatus idling 5 minutes while checking whether enough oil tank, pump noise is normal, the hydraulic unit and pipes, fittings, if the piston leakage phenomenon.
Scale thermal conductivity gas oil fired 1000kg steam boiler 1 ton boiler in stock is only one out of steel gas steam boiler efficient and environmentally friendly use of non-corrosive cleaning agent in the cleaning process of cleaning the boiler. This will cause the device to the metal tube is exposed to the primary colors, and reduce the effects of biological fouling algae sludge. After ignition gas steam boiler, furnace and to observe the temperature of main steam. Main steam pressure rises, the boiler flue gas temperature significantly higher ignition. If the temperature does not rise, you should immediately to the scene to check the oil gun fire. Scale thermal conductivity gas steam boiler is only one-tenth of steel. When it is scale on the heated surface, which will hinder the heat transfer effect. To maintain the boiler output constant during use, the need to increase the temperature of the combustion side. Gas-fired steam boiler furnace exit temperature rise, increasing the loss of gas steam boiler scale on the device can effectively reduce the water wall heat transfer, the temperature of the water is likely to lead to an increase in the wall, resulting in a wall of water burst. When the gas steam boiler, the furnace will be a series of chemical and physical reactions. During use, it will be effective to form a dense and hard scale on the heating surface, which will lead directly to heat exchange. Due to the scale and efficiency while reducing corrosion can lead to heat gas boiler absorption.
Water wall boiler tube leak or burst phenomenon how to do 1, the normal water flow is not greater than the steam flow. 2, the furnace pressure transient and unstable prejudiced. 3, tube leak detection alarm device. 4, the furnace may not tight at the outward discharge gas and water vapor, and a significant leakage sound. 5, the main steam pressure drop. 6, boiler combustion dark flame instability caused by severe boiler fire. 7, when the induced draft fan is automatically cast, abnormal static vane opening is increased, the current increases. 1 reason, the presence of water wall tube material defects or post-production, the installation of the damaged pipe, poor welding quality. 2, the inner tube fouling overtemperature. 3, the inner tube corrosion. 4, water wall wear. 5, the long-term high load operation, furnace coking, coal sulfur corrosion caused by high temperature water wall. 6, improper combustion, flame deflection. 7, in the possession of bad foreign body, the water cycle. 8, the wall of the long-term over-temperature operation. 9, the temperature difference between waterwall tubes, mechanical stress crack. 10, the normal exit or drain sootblower steam punctured tube. 11, smashed chunks of coke furnace water wall tube or serious explosion occurred, resulting in water wall tube suffered external damage. 12, boiler overpressure long run. 13, the boiler starts to heat up, step-up too fast. 1 process, the leakage should try waterwall tubes outage. The leakage is not serious, while still capable of maintaining operation, note that each of the automatic operation when the device, if not normal, it is cut immediately to the manual, if necessary, may be down, down-load operation. Closely monitor the development trend of damaged parts, good accident anticipation, application shutdown as soon as possible. 2, if the leak is serious, the bursting point temperature after a sharp rise in quality work, leading to serious over-temperature wall, unable to maintain the normal operation of the boiler or threaten the safety equipment, emergency shutdown provision should be processed, when the steam temperature to protect the action value, the protection does not move, should immediately hand MFT. 3, note that the operation of the electrostatic precipitator, to strengthen the inspection checks, to prevent fouling, and the electrodes ESP hopper, pipes and the like plugging air preheater ash. 4, after the shutdown, should retain ID fan, the furnace pressure is maintained constant, there is no discharge to be stopped after soda ID fan.
