The double horizontal pot water tube commercial boiler 8t factory price laos is mainly composed of upper and lower horizontal pots, convection tube bundles, water wall tubes, down tubes and headers. The front part of the boiler is a furnace, and a water-cooled wall is arranged around the furnace; the upper and lower horizontal drums are located at the rear of the furnace, and the two drums are connected by a curved water pipe. Most of the combustion equipment uses superheaters, economizers and air preheaters. The high-temperature flue gas flows from the upper part of the furnace to the convection flue through the heater. It first rises upwards and then rises in an S shape, flushes the convection tube bundle laterally, and then folds down into the tail flue, and then passes through the economizer and air. The heat exchanger is exhausted by an induced draft fan and a chimney. The boiler evaporation is generally less than 20 tons / hour (t / h), the working pressure is less than 2.5 MPa (MPa).

Steam commercial boiler 8t factory price laos is one of the indispensable devices in the pharmaceutical industry, decoction of Chinese medicine, medicine drying, sterilization, cooking gum, drying, tabletting and capsule production processes, a large amount of steam will be used. West Libang Pharmaceutical Co., Ltd. is a pharmaceutical research and development, production and sales of high-tech enterprises, the existing anesthesia, cardiovascular, child immunization, pharmaceutical raw materials, pharmaceutical excipients, nutrition series of six automated production lines. With the increasing strength of China's environmental protection, some high-pollution devices are making the transition to clean environmental protection. Libang Pharmaceutical respond positively to national coal to gas policy, decided to change the existing coal-fired boilers to clean better gas steam boiler. Fast boiler with strong comprehensive strength in the field of clean energy, Libang Pharmaceutical after conducting comprehensive consideration, determined to cooperate with the fast boiler. The two sides further understanding, party fast technical engineers according to production needs state power, and soon its development of specific solutions for its recommendation of a 6 tons of steam condensing gas steam boiler (WNS6-1.25-Y.Q).

This paper introduces the common faults of steam commercial boiler 8t factory price laos 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.
