Steam pharmaceutical industry steam atmospheric boiler dealer and hot water boiler inspection and sludge screw pump works fast boiler's Henan Xiao Bian now introduce steam boiler and hot water boiler inspection and sludge screw pump working principle On the steam boiler and hot water boiler inspection three major step routine testing is the most basic test. Because of internal and external boiler as a whole, we must first conduct a basic test. Routine testing basic skills test is working boiler, thus requiring inspectors should have more extensive testing and analytical skills. First, inspectors steam boiler and hot water boiler in the boiler inspection, they should prepare the following tools: 1,0.25-0.5 kilogram pointed a hammer; section 2, a good three flashlight; 3,155 mm ruler one; 4,2 meters a steel tape; 5,310-500 mm a straight ruler; 6,5-20 each a magnifying glass and a mirror; a 71.3 mm inner and outer calipers; 8, self-arc a small model scale and a soft curve; 9, an ultrasonic thickness gauge; 10, recording tools and protective equipment I. Second, the steam boiler and hot water boiler Appearance test: test boiler body structure and the respective pressure element is reasonable, the presence of any defects and welding pressure element metal surface joints, such as corrosion, wear, cracks or obvious from the groove, modification, bracing and without fracture connecting seam, weld surface defect status. When tested suspected crack may occur somewhere, But, it can not verify visually, then you can use a solution of nitric acid concentration of 10% of the erosion of the suspicious place, wipe, and then observed with a magnifying glass to determine whether a crack. There swag scale adhered to the steel sheet needs to be tested when the test hammer tip may be used to scale, rust knock, carefully tested after wiping. Third, the hot water boiler steam boiler and hammering inspection: when testing, with the test hammer percussion pressure receiving portion being tested member, tactile feel with auditory, visual inspection methods to determine the presence or absence of a defect. Proper understanding of this method, the degree of judgment to do right, is basic reaction boiler inspector whether a solid aspect. Test hammer test used, is a flat round, the other end is pointed, with a handle made of solid material adjacent to a hammerhead neck portion of the handle to the car, so that when in use the handle on the flexible, in order to increase feel stretch back to size to determine the test case. Sludge is the use of a screw intermeshing screws or the volume number of the change in absorption, the volume of the liquid discharge pump rotor. Active screw extending through the pump housing by a prime mover driving the stuffing box. Active driven screw and screw threaded in the opposite, a left-hand thread, the other a right-hand thread. Sludge screw having a wide flow range, the discharge pressure, high efficiency and stable characteristics of the work, but the process is complicated and the manufacturing cost. It is suitable for transporting oily liquids, also gas-liquid mixed phase fluid transport, the high viscosity fluid, such as acrylic slurry, etc., it is widely used in the oil, synthetic rubber, synthetic fiber production. Henan is committed to fast boiler steam boiler manufacturing, product quality, reasonable prices and widespread industry praise, if you have any needs, please contact us!
Dairy production and processing sectors, need a lot of steam on food drying, sterilization, stereotypes, such as processing, steam pharmaceutical industry steam atmospheric boiler dealer essential. Xinjiang Ake Su Xinnong Dairy Co., Ltd. as a local brand, has a large market users. 2016, Akzo increased demand for dairy production, the original steam boiler company can not meet today's production needs. In the same year, Akzo dairy cooperation with our company, signed a series SZS 6 tons of steam pipe steam boilers, steam support for the dairy industry dairy production Aksu.
Ordinary gas-fired pharmaceutical industry steam atmospheric boiler dealer during operation at high altitudes, there is insufficient output, and low aspects of the problem of thermal efficiency.
Henan run Q & Gas Boilers (b) 1. Internal gas pharmaceutical industry steam atmospheric boiler dealer drum Henan mainly those devices and how they effect the arrangement position A:?? Henan gas boilers with capacities of different parameters, it is not exactly the drum inside the device - like, now at high pressure and ultra-high pressure boilers drum example, describes internal devices, their arrangement and a major role. Along the length of the drum is mounted at both sides of a plurality of cyclones, each cyclone barrel top is arranged a louver (wave plate) separators, their primary role is to rise by the tube into a mixture of soda and water vapor will be the initial separation. In the upper steam drum, steam cleaning horizontal mounting plate, on which the cleaning water supply layer, when the steam passes through the water layer, put dissolved or carried vapor partial turn salt was dissolved in water, to reduce the steam salt. Near the top of the drum is provided with a perforated plate, a uniform flow in the ascending vapor drum, and the water vapor is further separated. About 150mm with the drum center line of the discharge pipe opening accident; continuous blowdown piping is provided at approximately 200mm port under normal water line, and then disposed below the dosing tube. Also installed at the entrance of the downcomer cross blade. To prevent a drop generating swirling nozzle causing drop tube bucket with steam. 2. Continuous outfall mouth Henan gas boilers are generally installed where? Why? How much sewage rate? A: Top nozzle Henan continuous gas boiler 200 is generally mounted on a drum at the lower 300mm normal water level (i.e., "0"). Since the pot of water evaporation continuously gradually concentrated in the vicinity of the surface of the water with the highest salt concentrations. Therefore, continuous blowdown piping port Henan gas boiler should be installed in the region of the maximum boiler water concentration to high concentration continuously withdrawing boiler water, supplemented with clean water supply, thereby improving the quality of boiler water. Henan gas boiler blowdown rate is generally about 1% of the amount of evaporation. 3. What pot of water treatment dosing in Henan gas boiler drum sense Answer: the pot to prevent the fouling, if simply to remove the water contained in the outer boiler feed water hardness, needed more equipment will greatly increase investment; and plus? cauldron blowdown, heat loss not only increase the working medium, can not be eliminated pot residue water hardness. Thus, in addition to using external boiler water treatment, but also on the water in the boiler pan dosing process, remove the pot residue water hardness, to prevent boiler scaling. The method of addition of phosphate which is in the pot of water, so that calcium and magnesium ions and phosphate ions bound water pot, Rong generating hard water precipitation sludge, sewage regularly excluded, so to maintain a certain boiler water phosphate, neither fouling and corrosion, but also to ensure the quality of steam. 4. What Henan gas boiler regularly sewage outfall aim is installed in the mouth where A:?? Because Henan pot of water gas boilers containing rust and dosing process water precipitated the formation of slag and other impurities deposited on the bottom of the water circuit, regular sewage the purpose of the water is periodically discharging slag and other impurities precipitate, increasing the pan of water quality. Periodically outfall generally located in the lower header, or concentrated water wall lower portion of the downcomer.
