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.
When operating the energy saving distributor boiler 8t, what is the "waters"? When the boiler water gauge did not see the water level, wash first with water table method to determine water or with water. If it is determined that water, water level meter for even the highest fire tube boiler is lower than the boundary, emergency shutdown immediately, reducing the furnace temperature, the main steam valve and to close the valve. For larger capacity of water, and the water boiler higher than even the highest fire tube boiler industry, can be "called water" method to determine the severity of water shortages, in order to take appropriate measures. When the "waters" to determine water shortage is not serious, it can continue to the boiler feed water, the water level returned to normal, gradually warming up to start burning equipment, boost operational. Through the "waters", sentenced to severe water shortages, have emergency shutdown, non-blind feed water to the boiler. Never allow chances attempt to cover liability resulting boiler water shortage and water supply blind. This wrong approach often lead to disaster, expansion of the accident, causing the boiler furnace explosion and crash. The method of "waters" are: (1) turn on the water tap open water table. (2) stripping off cock. (3) close the water cock. (4) and then turn on the water tap is closed. (5) and then turn the tap water, to see whether there is water out from the water pipe is connected. If out of the water, the water is slightly; if no water appears, proved to be a serious shortage. "Waters" process can be repeated several times but not delay too long, so the expansion of the accident. "Waters" principles of operation are: After draining cock open, then close the steam, the water pipe connected between the water cock and the table, so that a large vapor communication with the water table, water gauge pressure is zero. Then again closed drain cocks open water pipe connected between the water cock and the water table, because the pressure within the drum water level higher than the inner pressure table, if the drum water level is in the vicinity of the water pipe connected to the water vapor stream is brought into water table, which shows the extent of water shortage is not serious. If the "waters" has never been in the water table level, water is considered more serious.
How to deal with the causes of water shortage in Fangkuai energy saving distributor boiler 8t? (1) the causes of water shortage a, the failure of water supply regulation device or the failure of water supply automatic regulation were not discovered in time. B, water level gauge, steam flow meter or feed water flow meter is not correct, which causes the operator to misjudge and operate wrongly. C, the boiler load has plummeted. D, water pressure drop. E, boiler sewage pipe, valve leakage, excessive discharge. F, water wall, economizer tube burst or leak. (2) the phenomenon of water shortage: a, the water level in the drum is lower than the gauge. A set normal water level. B, the water level indicator is below the normal minimum water level standard, and the water level alarm signals low water level. C, superheated steam temperature rises. D, the feed water flow rate is abnormally smaller than the steam flow rate. (3) when the boiler steam pressure and feed water pressure are normal and the drum water level falls below the normal water level, the following measures shall be taken: a, Compare and flush the drum water level gauge to see if it is correct. B, water supply regulation from automatic to manual, if the automatic non-electric, can be changed to manual, and increase boiler feed water. C, if treated by the above method After that, when the water level in the drum is still low, the discharge gate of the boiler and economizer should be checked. If it is found that the economizer is damaged by a large amount of water leakage and affects the water level and water circulation, the boiler should be stopped by the dispatch. D, if measures are taken to restore the water level, the water level shall continue to fall, and when the allowable minimum water level is reached, the dispatch room shall be reported and the boiler load shall be reduced. E, if the water level continues to decrease and disappears from the drum water level gauge, the boiler unit operation shall be stopped immediately and the upper water supply to the boiler shall be prohibited. (4) due to carelessness of the operator, the water level shall disappear in the drum water level gauge. Failure to detect them in a timely manner should be dealt with in accordance with the following measures: B, when the water level appears in the drum water level meter, the boiler feed water can be increased and the water level should be restored. C, when the water level fails to appear in the drum water level gauge, the boiler shall be shut down immediately and the water intake into the boiler shall be strictly prohibited.
