Vertical supplier steam boiler 8t tajikistan will affect a large fan vibration running long vertical steam boiler fan speed operation, large mechanical wear and vibration, especially at low load unit, fan baffle throttle more, fans work in the unstable region, easily cause fan vibration. In addition, low vertical coal-fired steam boiler induced fan system automation level, can not adjust, low operating efficiency, fan vibration is relatively strong, not only equipment maintenance costs, but also poses a potential threat to the safe operation of the unit. Vertical steam boiler can be considered, Fan Vertical coal-fired steam boilers high pressure transducer, induced draft fan boiler using frequency control. To do the following: First, each exhaust fan arranged a high-voltage inverter. The inverter is connected to the high speed winding machine. Low speed winding of the motor coupled to the low-speed circuit breaker for the bypass operation when the inverter failure. Then, between the drive motor and additional disconnecting switch cabinet, electrically connected to the low-speed circuit breaker. High motor speeds, the door closing isolation knife, the low-speed circuit breaker closing prohibition. Motor bypass operation, the isolation switch off, the low-speed low speed motor control circuit breaker. Output frequency of the inverter is controlled by the speed control signal in accordance with the negative pressure 4-20mA vertical coal-fired steam boiler furnace start and stop the inverter output control signal by DCS.
In the last meeting on April 16, the hard efforts of audits and company officials of president Mr. Lu Haigang couplet review group to pay thanked rigorous review and couplets group work style, professional skills to express my sincere admiration. Ms. Jiang Lianju warranty division said it will continue to improve the ASME quality control system to ensure produce sophisticated products comply with ASME standards. According to ASME certification process, after the on-site audit, the company will obtain certification and stamp issued within 20 working days, this will be the development of our company in the history of another "milestone" event.
We are a professional boiler manufacturer and exporter with 70 years history in china. Very sincerely looking for long-term win-win business here.
With the improvement of material living standards, modern people generally have higher requirements for the temperature state of their environment. Since the advent of research and development, condensing boilers have successfully attracted the attention of a large number of social groups. After an in-depth understanding of the performance of condensing boilers, many social groups are scrambling to buy. At the same time, the installation of a full range of condensing boilers has become an urgent problem for many buyers, so what preparatory work should be done before installing the condensing boilers?
1, it is well known that environmental protection has become an issue of great concern in today's society, and the relevant departments have formulated a series of rules for the installation and use of boilers. Those enterprises and institutions that do not meet the requirements will not be able to install the condensing boilers smoothly even if they have purchased them, so be sure to verify that they are qualified for installation before installing the condensing boilers.
2. The second item is to check whether the parts are complete or not the existing condensing boilers in the market usually need to go through many links from the factory to the formal operation in which the transportation and storage are the necessary links for the boiler to be put into the market. If the relevant work is not done in these links, the performance of the condensing boiler may be affected. Therefore, it is necessary to check the appearance of the boiler and the completeness of the fittings before installing the condensing boiler.
3, the installation of auxiliary mobile equipment will be ready because most condensing boilers are relatively large and difficult to move, if the installation depends solely on manual handling or movement is not very realistic. Only by means of large-scale hook-hanger equipment can the condensing boiler be placed in the intended installation position, so the enterprise that buys the condensing boiler will need to prepare the auxiliary moving equipment before installing it.
