Cold days, as long as the use of pressure hot water chinese best quality industrial electric hot water boiler in place can feel like spring-like warmth, enjoy the convenience brought by the hot water. Suitable pressure hot water boiler can greatly enhance the quality of life of users. Pressure hot water boiler easy to use, but the user at the time of purchase, there are also confused how to buy, we bring you a look at how to choose the right pressure hot water boiler? 1, determining the purpose of buying boiler pressure hot water boiler to take into account, due to the use of different environments, user needs are also different. If the client needs heating, heating should be selected specific pressure hot water boiler, the hot water circulation pump circulating the hot water in the pipe, then the radiator (also referred radiator) for distributing the heat required to heat every corner. But only need to select the hot water supply of hot water dedicated pressure hot water boiler, hot water circulating through the heat pump so that the hot water tank is circulated, can achieve the purpose of supply of hot water; there are some users for heating and hot water there needs to be selected may increase the heat exchanger in the pipe system use either of pressure hot water boiler. 2, the heating area is determined, when the optional water pressure hot water boiler, to determine the amount of water used in the heating area or the desired properties, and then through the circulation amount calculated to determine how much capacity the boiler, accurate and scientific the calculation and design can satisfy normal use will not cause waste of resources. 3, to determine the fuel, style pressure hot water boiler equipment, electric hot water boilers, coal-fired and gas-fired hot water boiler These three types are more common. Electrical use electric water boilers using coal and natural gas as an energy source as an energy source, coal, gas hot water boiler.
Electric chinese best quality industrial electric hot water boiler electric boiler cleaning method is mainly used in place of a large area of guesthouses, hotels, colleges, factories, etc., in the course of its work, a long time after the surface or the interior will scale phenomenon, this phenomenon greatly affect the equipment, the following it'll tell you about cleaning method: 1, acid cleaning method: ① this pickling solution can not only clean up the boiler scale (except when nitrates scale, add hydrofluoric acid), and very little corrosion gas hot water boiler. ② descaling pickling process using hydrochloric acid or nitric acid, most of the cleaning. Pickling solution by adding nitric acid or hydrochloric acid was added inhibitor of the corrosion inhibitor composition. 2, the mechanical descaling method: when the electric furnace with a loose boiler scale and slag, so that the cast iron hot water boiler shutdown cooling, boiler water let go of, after washing with water, can be used flat shovel, wire brushes, and a motor milling descaling header. 3, alkali cooking cleaning law: ① alkali cooking method is simple, relatively small side effects. ② alkali cooking method of cleaning descaling, pickling cleaning effect than the difference method, but since a base boiled loose scale, so it is difficult for, may be a cooking method I with a base with hydrochloric acid cleaned scale before acid pickling deal with. Scale electric boiler efficiency is an important factor in the life and influence, in order to ensure it is safe to run the economy, the need for a reasonable scale clean-up work, so essential to get rid of scale, reduce equipment failure and reduce damage.
This year, located in Guizhou Tongzi County and located in Heilongjiang Harbin has two chinese best quality industrial electric hot water boiler explosions accident, after investigation, the accident was produced in the installation link, there are companies the main responsibility for the implementation of incomplete installation link, confusion installation and construction management , unauthorized commissioning, pressure testing irregularities, installation supervision and inspection to ensure the role of the missing and other problems, leading to a boiler explosion occurs, causing adverse effects for the personal and property safety.
Market supervision bureau to draw lessons from the accident, in order to avoid explosion due to boiler installation problem from occurring again, issued a notice warning of the risk of boiler installation link. Details are as follows:
The boiler safety related technical specifications, the entire boiler manufacturing unit can be installed (set) mounted boiler units produced. Boiler manufacturing unit undertake installation work, should meet the following requirements:
The manufacturer should be dedicated departments boiler installation work, set up to cover the boiler installation quality management system, equipped with the necessary resources to installation conditions. Boiler manufacturing units should strengthen sales management, through specified in the sales contract if the terms of the unit responsible for the installation of boilers, etc., to prevent sales by the manufacturing license qualification units or organizations which are not allowed to undertake the unit personnel to carry out boiler installation work. Where specified in the contract manufacturing sales unit responsible for the installation, on-site installation work must be sent by the company to complete the installation personnel shall not be subcontracted to other units (safety specifications are allowed in the assigned project except). Indicate the sales contract to this unit responsible for the installation of the boiler, installation of the unit must have the appropriate license installed. Responsible for the installation of the units should strengthen safety education and skills training for installation personnel. Find that the installation quality and safety aspects of the occurrence of an accident or appears illegal activities, special equipment safety supervision institutions should be punished according to the law to install the unit.
Boiler installation units should strictly enforce the relevant safety standards and technical specifications to ensure the quality and safety of boiler installation, the unit should be installed at the installation site set up signs stating the name of the license holder of the certificate, license project, license number and items the person in charge, who is responsible for safety and quality, commissioning personnel, supervisory inspector's name, unit and telephone. Boiler commissioning and commissioning, operation must be performed by a licensed boiler operator. Before the boiler installation, inspection and acceptance by the relevant formally delivered, installed units should be hung in a prominent position boilers warning signs with the words "banned" and take effective protection and quarantine measures to ensure that the boiler system can not be ignited or boost . In addition to the need to debug, the cabinet can not be energized, the fuel valve is in a closed state should be like. Use blanking panels of the boiler pressure test, the test should be removed immediately after the end of the Blind.
Boiler boiler installation situation before construction units should be installed by informing the local special equipment safety supervision and management departments, and submit an application to install Supervision, Inspection and supervisory inspection agency. Where Supervision and Inspection uncommitted boiler installation project may not start.
Supervisory inspection agency should be strictly in accordance with the "Boiler Inspection Rules", according to the supervisory inspection protocol and progress of the project requirements, arrangements for the implementation of the supervisory inspector boiler installation supervisory inspection. A class of control points, the supervisory inspector must be at the scene confirmed to meet the requirements, the installation unit in order to continue with the work. Supervisory inspector shall, at the start that is to the construction site, in the whole process of site supervision to pressure test, shall not be used after the witness confirmed that and how do fill supervisory inspection program Supervision, Inspection and replacement process when the boiler pressure test.
Boiler manufacturing unit in particular is responsible for boiler installation of manufacturing units and boiler installation supervisory inspection agency, should an accident lessons learned, giving top priority to further implement the main responsibility and checks responsibility, strengthen the boiler installation management to ensure the quality of the installation work, protect the boiler safety.
