Steam boiler When should an emergency shutdown when the bath steam boiler for sale Shanghai encountered the following situations, gas boiler manufacturers need to take emergency shutdown measures: (1) When the steam boiler water level gauge water level drops below the lowest water level, through the "call water when the "law also failed to see the water level. (2) increase the boiler when the water level continued to decline up time. (3) water supply system failure, unable to supply water when the boiler. (4) water level gauge and a safety valve failure, can not guarantee the safe operation of the boiler. (5) When the control valve and the drain valve malfunction when closed lax. (6) when the pressure receiving surface of the waterwall tubes or boiler smoke tubes bulging or cracking occurs, the furnace wall, collapsed down occurs when the front arch. (7) In case of failure of a safety valve, pressure gauge displays the boiler overpressure operation. When by the above situation, should immediately shutdown, should turn off the blowers, the door opened quickly, quick rotation of the grate, the furnace temperature is lowered to withdraw the fire, the coal supply is stopped. When the boiler overpressure, open the emergency vent valve provided on the sub-cylinder is discharged down. When the furnace severe water shortage, should not panic, in order to avoid operational errors. At this time, non-watered furnace. Then reduce oven temperature to find the reasons to be processed.
In recent years, Hebei Province People's Government to respond positively to Blue Sky Battle action plan promulgated by the state, and all of 35t / h coal-fired boiler and below in the Hebei province out of the transformation process. First Hospital of Baoding respond positively to the call of the provincial government, eliminate serious pollution of the original coal-fired boiler hospital, citing energy saving bath steam boiler for sale to natural gas as raw material. After a series of market research, WNS Series Split hospital condensing gas boiler boiler other fast soft spot.
Principles of bath steam boiler for sales and solutions hydraulic external gear of Henan fast boiler's small series with you about the principles of steam boilers and solutions Steam Boiler hydraulic external gear in accordance with the fuel (electricity, oil, gas) can be divided into electric steam boilers, oil three kinds of steam boilers, gas and steam boiler; constructed according to the steam boiler can be divided into vertical, horizontal steam boiler, steam boiler compact than a single, double return of the vertical structure, large steam boiler return of more than three horizontal structure . If the classification according to top standards, in the form of steam boilers on the lot, would like to give an ordinary packaged boiler say four tons vapor. Water in the steam drum is heated to become vapor, fire emits heat in the furnace, it is the principle of the steam boiler. Steam boiler combustion section and drive means by a chain grate, a combustion chamber together with the pan rack frame formed on a grate composition. Four weeks envelope refractories. From coal fired into the hopper, the shutter coal front portion while sealing air control seam thickness. Blowing into the combustion chamber is a lower place, such steam boilers greater resistance, require forced air. Steam boiler cinder burn out, the rear portion of the grate by the "beak iron" discharged from the slag out of the furnace feeding machine. Steam boiler flue gas from the back of the boiler, the steam drum of a boiler return line before the smoke tube, returned by two return rear smoke tube, and then into the dust separating ashes, and then discharged through the chimney draft fan. These are the works of steam boilers, steam boilers run course, ultimately, other devices, such as induced draft fan not only bear the task of exhaust fumes, or negative pressure necessary for operation of the steam boiler. As well as pressure vessels, thermometer, safety valves, pressure gauges, pumps, steam pumps, and so on. They are essential for steam boiler work. Pump leaks. Gear pumps for leaks during operation, leading to its actual output is smaller than the theoretical flow of traffic. The main channel is leaking gear pump: through the gap between both surfaces and both side surfaces of the gear cover side leakage, accounting for 75% to 85% of the total leakage of the pump; radial gear tip circle between the inner hole and the pump CLEARANCE ; gap by engagement of the gear leak. The gear pump due to the presence of a leak, so that the output pressure do not increase, the influence of the use of a gear pump. In order to solve the low gear pump output pressure problems, may be employed on both sides of the elastic gear plus floating collar or baffle manner, to reduce the leakage of the gear pump, the gear pump to increase the output pressure. Radial force imbalance. In the gear pump during operation, the pressure acting on the outer gears are not equal, resulting in the gear and bearing at the axle radial imbalance force. This unbalanced force will accelerate the radial bearing wear and reduce the service life of the bearings, the gear shaft deformation can also cause friction with the inner hole of the addendum pump, pump damage, so that the pump does not work. The solution generally adopted is: ④ opening pressure balancing grooves to the pump, the high pressure oil introduced into the low pressure zone, but will increase the pump leak, the influence of the volumetric efficiency of the pump; ② size reduction oil pressure chamber, acting on the teeth the pressure area is reduced, thereby reducing the radial force imbalance.
Henan gas boilers What are the advantages and disadvantages? Henan gas boiler is a clean burning natural gas for industrial boiler energy section of industrial production output of hot water and steam. After the recent years, increasing environmental pressures and an increasingly serious energy crisis, the government has introduced a series of laws and regulations on the promotion of energy conservation and emission reduction, to encourage new energy promotion, the gas boiler should be transported from Henan, breaking coal boiler "thriving" situation. Compared with conventional oil-fired boilers, coal-fired boiler, gas boiler Henan has unparalleled advantages, mainly in the following areas: 1, Henan artificial gas boilers and low consumption of water and electricity costs; 2, gas-fired boiler flue gas of Henan or promote condensation energy technology, it greatly enhance the thermal efficiency further, when the exhaust gas temperature Henan gas boiler is reduced to 80 degrees or less, up to 95% efficiency; 3, Henan environmental clean gas boiler, a small area of the boiler, low failure rate, significantly improve the use of units on-site environment, adequate supply and lower prices, environmental requirements higher cost areas of comparative advantage of obvious; 4, due to the Henan gas-fired boiler using clean energy, so when burned does not produce soot and dust in the furnace, so the operating life than other types of boiler long. However, due to the environmental advantages of natural gas and energy in a growing proportion of supply and demand and Jiazhiguilv bound to make the country in the future and gradually it with other primary energy prices linked to float, its long-term price trend will gradually open. In addition natural gas shortages in some areas or seasonal shortages also affect the reasons for its further promotion. On the whole, the use of gas-fired boiler more good than harm Henan, Henan to promote the use of gas-fired boiler is still the trend. Van de force as a professional boiler boiler supplier, in terms of Henan gas boiler series of development and exploration, successfully developed a low nitrogen gas boiler Henan, have made outstanding contributions to technological innovation in Henan gas boiler.Free Chat
