single drum sawdust fired grate boiler
Enterprises in the selection pressure gas single drum sawdust fired grate boiler, what most noteworthy?
Gas boiler water system of a pressure vessel and a closed piping components, by the fuel-fired heating, withstand greater than atmospheric pressure during operation, a certain risk, is the subject of special equipment supervision sector of particular scrutiny.
Zhengzhou Sunrise Optoelectronics Technology Co., Ltd. by the Dongxu Group, Henan Province, the state-owned asset management companies and Zhengzhou Investment Holdings Limited jointly made, mainly engaged in flat panel display and solar industry design materials, manufacturing and sales operations. Sunrise Optoelectronics project has been put into a production line, the second phase will continue the expansion, three new production lines to meet the production needs of Project Phase II, Sunrise Optoelectronics urgent need to increase new single drum sawdust fired grate boiler equipment. After investigation and screening of a number of boiler brands, determined to cooperate with the fast boiler, steam signed a 10-ton integrated condensing gas steam boiler (WNS10-1.25-Y.Q).
Based on the different ways of acid process, our company has developed sulfuric acid-making waste single drum sawdust fired grate boiler and pyrite acid making waste heat boiler. They are applied in the recycle of sulfuric acid waste heat and power generation projects. They are the ideal equipment for enterprises saving energy.
This paper introduces the common faults of steam single drum sawdust fired grate boiler and submersible pump steam boiler water level device, causes and solutions. 1, the common problems of steam boiler water level device and its causes: 1, the installation of water level device is too low; 2, water level device, water pipe is too thin; (3) when there is low level device or when using automatic display instrument of water level, there is only one level device on the boiler; 4, water level device discharge water screw plug no ground drain pipe; 5, one water level on the drum is valid, while the other is damaged; 6, the cock on the water level cannot be screwed; 7, the cock on the water level is leaking, the water leak; 8, the false water level is displayed on the level meter; 9, the pot is not screwed up; 7, the cock on the water level is leaking, 8, the false water level is displayed on the water level device; 9, the pot The water level of the two water level devices on the cylinder is inconsistent; the glass tube of the water level device is often broken; 11, there is no protective device for the glass tube of the water level device; 12, the high and low water level indicator on the glass tube plate of the water level device does not indicate the red line; 13, water level glass tube plate is too dirty, the water level can not be observed clearly. The main reason for the above 1 / 4 is the dislocation of design, installation or modification. When a steam boiler is equipped with a low-level water level, there is only one level on the drum, because the balance of the low-level water supply is short-circuited (it was not detectable at the time). The resulting low water level shows a high water level (so-called full water). And the water level on the drum shows a low water level (or even may not even see the water level), when the boiler worker will check the water level on the drum because he is unable to immediately determine the actual water level of the boiler. Therefore, the container will delay the time and the boiler serious water shortage accident. Some even over-trust the display water level of low-status water level devices, and take a large number of sewage discharge, mistakenly treat the steam boiler water shortage as full of water accident, accelerate the occurrence of accidents, there is a precedent for the occurrence of such accidents. Then, the main cause of the above-mentioned 5 # 9 failure is that the boiler does not flush for a long time and does not carry out daily maintenance, which causes the water level of the boiler to be kept in operation for a long time. Cork rust, steam, water pipe clogging, or lack of fillers or aging deterioration. The phenomenon of false water level, except that steam, water pipe or cock is blocked, may also be caused by the dislocation of the connection between steam, water pipe and water level apparatus; Steam, water cock handle position misplaced resulting in cock closure, but also due to poor water quality, steam and water in the boiler concomitant and false water level. The main cause of glass tube breakage of water level apparatus is that the center line of steam and water cock is not in a straight line, the glass tube has bending stress, and the glass tube has no expanding gap. The water level device is being blown directly by the cold air at the window, as well as the poor quality of the glass tube and so on. Submersible hydropower Pumps are mechatronics high-tech products. In recent years, great progress has been made in seal, insulation, cooling and monitoring of submersible pump, and the automatic coupling of pump and outlet pipe has been successfully realized, so that the popularization and application speed of large caliber submersible pump is accelerated obviously. As a result of saving investment in engineering, the submersible electric pump station can be installed and overhauled quickly, the operating conditions are greatly improved, and the reliability and service life of the equipment are significantly increased. At present, our country not only produces and installs axial-flow pumps and mixed-flow pumps with large caliber below 900 mm, but also produces large-scale submersible pumps with a diameter of 1.4 meters and 1.6 meters for submersible electricity. The technical popularization of pumping station has laid a good foundation. Divers are not afraid of flooding, but also have the advantages of rapid removal and installation of good mobility, can cope with the sudden rise of water level, chestnut chamber flooding and other sudden changes, large-scale submersible electric pump changes.
