china gas fired water tube steam boiler supplier
Principles of china fired water tube steam boiler suppliers 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.
Safety rules china fired water tube steam boiler supplier steam boiler production, life indispensable important equipment. Boiler room is a vital part of my unit. Steam boiler having a high temperature, high pressure characteristics in use. Such as poor management, will be an accident, causing casualties, the production interruption caused serious losses to the school and state. So each time fireman and maintenance personnel to maintain a high degree of responsibility in their work to ensure the normal operation of the boiler, strictly adhered to. A strict compliance system fireman job, to play unity, mutual help support the spirit of love. Second, improve and maintain boiler equipment, keep boiler room tidy, attention and strive to save coal, water, electricity. Third, in the boiler operation to maintain a predetermined pressure, temperature, pressure must not exceed. Pay attention to discern false water level. Bearing in mind the piping, valves and the valve opening position of the distribution status of operation. Gradually closing the valve should be open or closed on the side of the handwheel. Always pay attention to the old boiler malfunction and run accident precursor, should understand the reasons for treatment and prevention of its occurrence. When the need for urgent and emergency shutdown. Keep in mind the role of the distribution board each button, leaving no more than a total pressure during shutdown and cut off the power supply. Fourth, coal hopper raised or lowered, the lower non-coal hopper to stand, the suction air blower, fan, Java machine, near the transmission gear portion, careful attention to production safety, to prevent accidents. Fireman must stick to work, and offenders a fine deal. V. PREPARATION carefully, to prevent explosive materials
Foshan Gaoming Liu Ling Textile Dyeing and Finishing Co., Ltd. was founded in 2007, enterprises comprehensive strength, advanced processing equipment, detection means perfect, has a complete quality assurance system, the introduction into a large number of advanced production equipment, to ensure that technical standards and products stable to improve the quality of laid a solid foundation, enjoy a high reputation in the industry. Liu Ling Gao textile company twice with my company were to buy a 20 tons of steam and a whole 10 tons of steam condensing china fired water tube steam boiler supplier fuel gas for the production of textile dyeing and finishing company. Fang fast with strong comprehensive strength and improve the service system to win the favor of the other side, communication from the initial to the final boiler factory-installed square fast all uphold the customer's perspective to think and observe the service concept, for the sake of clever Liu Ling textile companies according to the company's actual demand for textiles, the development of specific programs.
Gas boiler price related factors and their dust: the gas boiler in the boiler, which is one of the website products, and further comprising a gas hot water boiler, gas china fired water tube steam boiler suppliers, gas oil furnace three. Therefore, it is necessary from a whole, to know and understand, so that we can help further their specific products, and at the same time, to increase the amount of their own knowledge in this area. 1. gas boilers and electric boilers, which one is better? Gas boilers and electric boilers, boiler compare the two, then, can not say which one is better, because there is no comparable. I can only say, under what circumstances, what kind of boiler more appropriate. Moreover, both the boiler, there is a range of different applications and features. 2. Gas boiler room, whether it takes 24 hours on duty? In addition, two tons of gas boiler, its price is mainly related to what?
