range from simple fire tube boilers to self

Boiler design is unreasonable result in uneven distribution of traffic in each circulation circuit. Heat too much deviation, solder angular, square, flat plate structure, the steel does not meet the requirements; good manufacturing and repair process. If the range from simple fire tube boilers to self welding quality substandard easily rupture.

Industrial steam range from simple fire tube boilers to selfs noise reduction method which reduces noise industrial steam boilers What are the methods? As long as the machine will sound during operation, but the decibels of sound, large and small, the sound becomes noise, high-decibel noise will make people feel irritable, headaches, noise on the human body much harm. The cause of serious human endocrine disorders and even mental disorders. This not only does not interfere with people's normal life, but also promote high-efficiency steam boiler operation. Boilers running noisy, more than people can afford decibels. But the high temperature flue gas boiler. If a closed acoustic mode, the device will not be heated and important equipment in the boiler combustion. Industrial steam boilers method of noise reduction: 1 reduction measures boiler pump: Boiler pump noise emitted usually caused by two noises: the noise and the noise flow pump structure itself. Flow emitted noise is periodic pulsatile pumping system at full speed, and high-speed turbulence or cavitation in the pump. Noise generated by mechanical vibrations of the pump structure or vibrations caused by pulsation of the liquid pumps and pipes caused. Pump and motor noise through the pipeline insulation and insulation layer or cover made of a sound-absorbing material, or the partition will be closed to reduce the pump and motor. Vibrating the wall of a noise insulating material may be partially absorbed and a control to reduce transmission of noise. The exhaust gas boiler noise reduction measures: (1) When the exhaust gas, high temperature and high pressure steam is injected to the atmosphere, the jet noise is generated. This noise can be injection orifice muffler, the muffler is attached to the vent orifice; (2) injection orifice muffler structure, pores having a size between 1 ~ 3mm, more than 5 times the center distance hole, open the total area of ​​the holes should be larger than the original area of ​​the exhaust gas of 1.5 to 2 times; 3 in the choice of the exhaust muffler, the muffler should be noted that the exhaust gas temperature and flow rates in order to satisfy the exhaust requirements, maintain a certain strength and corrosion resistance and note the freezing cold steam danger zone overpressure exhaust. 3. The boiler blower noise is mainly from three noise: fan noise caused by air vibration, noise and frictional noise between the rotor body and the operation of the vibration caused by the stator. In general, noise in the air is greatest, typically in excess of the sum of the other. Installation of the fan blades in the muffler, the entire semi-enclosed motor, noise propagation blocking the pathway from the housing, having good silencing performance. Whole-mount power fan may be mounted-enclosure, the entire blower housing can be built, inlet, outlet may hit the cover, and then loaded on the muffler.

From March 18 to start, Lujiang County, Anhui Province north of the Market Authority on the area of ​​internal security to carry out a special inspection of range from simple fire tube boilers to self pressure boiler; To ensure the safe operation of this special equipment, complete elimination of security risks.

The inspection mainly troubleshoot and eliminate hidden dangers in the management and operation of the boiler links exist, focus on examination of whether to establish safety management systems and procedures; whether to set security management or part-time security management staffing; whether workers with valid work certificate for employment; boiler operating records, inspection records and shift recording is complete; if the boiler for the use of registration; whether the inspection within the validity period; check valve is within the validity period, the pressure gauge whether the test within the validity period. Up to now, law enforcement officers dispatched 27 people, focus on examination of 12 times the focus of special equipment supervision units, hospitals, schools, boiler 20 times, do not meet the specified use in accordance with the boiler "Special Equipment Safety Law of People's Republic of China." requirements, issued a supervision instructions, requires immediate rectification unit, for there is no regular inspection of boilers or unqualified, shall not be put to use.
