Anyang City Minshan Nonferrous Metal Co., Ltd. is a collection of urban mining, renewable resources, energy as one of the economic wisdom of cleaning companies, mainly non-ferrous metal extraction and processing work. Company to conserve energy, cleaner production for the purpose of this concept coincides with the fast price 1t boiler brand. Thus, when the company in the purchase of the product boiler, and fast boiler almost hit it off, by the party to provide a fast 6 tons of steam integrally condensing gas steam boiler (WNS6-1.25.Y.Q).
WNS Accident Analysis of dry steam price 1t boiler brand 1, the low level alarm and interlock protection device is not put into use and the failure is the leading cause of boiler provided with low water level alarm chain protection and low water temperature and smoke alarm device. Prior to the incident, said the fireman did not know the level of low water level alarm and interlock protection device has failed. Only because of the economizer outlet flue gas temperature exceeds its limit emerging (designed for 150 ℃), resulting in constantly ringing alarm bells. Fireman turned off the alarm, low water level chain protection device is also close together. Incident, fireman not effectively remind the water, the boiler continues to operate in the case of water, until the drum from collapsing, cracking convection tube squib. Therefore, the low water level alarm and interlock protection device is not put into use and failure is the primary cause. 2, fireman staff is not strong sense of responsibility and lack of experience is a secondary reason for not timely fireman check the health of the boiler, the water level of the false appearance also have not been ascertain. Even if the water level remains normal, but with fireman experience, should determine the average time in Sheung Shui and take appropriate screening measures, so that when the value is less than the fireman experience or did not do to duty. If you regularly observed from the observation hole to the boiler, you can discover the colors and deformation heating surface, and to take action if the boiler severe water shortages. Flue gas temperature alarm occurs first, without making fireman ascertain the cause, any breach of the rules is closed. Moreover, since a long time to eat off-site procedures are also not shift, so this is the responsibility fireman accident. 3, poor management, poor leadership and management is another secondary cause 1) as companies focus only on the production of steam consumption usually very strict, while ignoring safety management, there is no factory fireman personnel safety training. 2) The enterprise security managers no security certificate management, and knowledge of low water level and low water temperature alarm and smoke interlock protection device is not put into use, nor hamper it. 3) flue gas temperature alarm limit adjustment protracted problem, which is not as competent leadership and a great relationship. 4) boiler room management system, check system is not perfect, no preventive maintenance program, so that long-term drain valve leakage state; while the setting of boiler maintenance system, but not implemented, resulting in low water level alarm and interlock protection device is in low water failure state.
The so-called safety valve on the one hand say: it is a price 1t boiler brand and pressure vessel and a pressure line valve, the drain having a pressure release or function, a relief valve; management rules from the perspective of such a safety valve efficacy installed on a steam boiler or pressure of the pressure vessel, a necessary condition is that he must be recognized quality and technical supervision departments.
Former vertical steam price 1t boiler brand overhaul what to do to prepare? Many enterprises in order to be able to produce sufficient power will choose to use vertical steam boiler, however, even if it is high quality and reliable vertical steam boiler, still produce some of the inevitable loss during use, so the need for maintenance on a regular basis, in order to be able to to discover and deal with these problems, avoid accidents. What you need to do to prepare it before performing vertical steam boiler maintenance? 1, to determine the category of boiler maintenance and repair information over the years of operation, security equipment, equipment defects, mechanical wear records based on vertical steam boiler, combined with the enterprise's production to determine the category of boiler maintenance, boiler repair plan to make arrangements. 2, in accordance with the necessary technical preparations vertical steam boiler overhaul category of standard items in the maintenance and improvement of equipment and projects, according to the quality standards of technical requirements, prepare plans and documents, the construction process of technical preparations. At the same time proposed raw materials, spare parts, tools and plans to make material preparations. 3, check to make sure a variety of repairs shutdown as planned quotas to stop boilers, vertical steam boiler for a detailed examination of the internal and external, proofreading boiler drawings for its consistent with the actual situation, evaluate the technical condition of equipment, changes and additions to the standard project content, and according to further modify and full materials, spare parts, tools. And to determine the large, labor quotas and minor repairs of equipment repair downtime quotas, make economic budget. 4, good maintenance arrangements for the security measures, the preparation schedule, designate a person responsible for the organization construction of power, with on-site technical guidance and quality inspection. In the construction process overhaul vertical steam boiler, strict quality standards to improve the quality of maintenance. These are the vertical steam boiler in the need to prepare well in advance of the preparatory work before the overhaul. For businesses, the purchase well-known vertical steam boiler is only the beginning to ensure the production of power, only if the correct operation of steam boilers, and regularly do maintenance to ensure vertical steam boiler can provide about as adequate power and heat , in order to play the power production enterprises.
