As a new technology and new product, the sonic dust remover can challenge the traditional sootblowing technology and must have its unique features and characteristics. This is mainly reflected in the cleaning effect, investment efficiency, safety and reliability, operation management, etc. Outstanding advantages. The generation of sonic cleaning technology is caused by the inability to solve the problem of accumulated dust in the traditional way of cleaning dust. To meet the increasing development of energy-saving and environmental protection, emerging technologies have been used for many years, sonic cleaning products. Has formed a scale, is a mature technology, stable performance of the stereotyped products, is undoubtedly the replacement product of traditional ash cleaning devices. We do not produce "shock wave" sootblowers nor do we comment on any "shock wave" sootblowers from any manufacturer. Only academic, technical, and economic aspects of sound wave soot cleaner and shock wave soot blower are compared for ease of reference. From a disciplinary perspective, both belong to the discipline of acoustics. "Shock" is also the content of acoustics research. Actually, it has been widely used as pulsed sound waves, such as low-power ultrasonic testing and high-powered seismic and nuclear explosions. The history of use as a sootblower began as early as World War II. The Germans used air guns, buds, firecrackers, etc. to remove dust from boiler fouling. The basic principle was to mix combustible gas with air, blasts and high-speed heat from explosions. The air flow acts on the ash deposit with low-frequency impulse shock waves. Here we describe only some of the reasons why we as acousticians do not develop "shock wave" sootblowers. Acoustic soot cleaners and "shock" sootblowers (also including similar products called "shockwave", "shock", "infrasound", etc.), both designed to harness the mechanical forces of the air To achieve the purpose of removal. The method of producing mechanical force is different, and the structure is different. From the academic discipline, it belongs to the discipline of acoustics. The sound waves generated by acoustic wave cleaners are called continuous sound waves, and are abbreviated as sound waves. ZHK series maintenance-free sound wave cleaners have no mechanism to adjust, and there is no movement or unstable structure. There is no possibility of operating machinery failure, and the generated sound waves are also continuously stable; the sound waves generated by the “shock wave†sootblowers are called pulsed sound waves, also known as shock waves, shock waves, etc. The gray device structure is pulsed continuous flow regardless of serial connection or parallel connection. The flow rate error is only controlled by the flow meter method. The performance of each ash soot is very large in fluctuation, and it changes suddenly and irregularly. Variations, different ash deposition characteristics, and different temperature sections, boiler ash blowing effect is very unstable. The name of its product is different from the manufacturer's custom. Therefore, the analysis and comparison of its basic mechanisms, performance, advantages, and disadvantages are completely objective. Both of them can be mathematically solved by the same wave equation, and only the boundary conditions are different. Graphs solved in both time domains: Graphs solved in both frequency domains: Comparing the two figures in the time domain, we can see: Acoustic eliminators can have continuous, repetitive and alternating mechanical effects. "Shock" can erupt in a very short period of time with a large, unidirectional mechanical effect. Comparing the two figures in the frequency domain, we can see: The frequency range of mechanical action of sonic clearers is limited to the audible sound band. The frequency range in which the “shock wave†exerts mechanical action includes not only an audible frequency band but also an infrasonic frequency band. From mathematical and physical analysis can be clear: The amplitude of the mechanical action of acoustic cleaners is less than that of "shock", but the duration of action may be longer than "shock". In addition, infrasound waves can be avoided within the frequency range where the sonic cleaning device exerts mechanical action. The magnitude of the "shock wave" mechanical action is greater than that of the acoustic wave cleaner, but the mechanical action is unidirectional, and it is easy to leave a dead corner of the cleaning. In addition, there are abundant infrasonic components in the frequency range where "shock" occurs mechanically.
WD615 series engine are the most famous engine in Chinese brand trucks. The technology comes from STEYR WD615 engine. WD615.87 is 290 hp engine , WD615.69 is 336 hp engine, WD615.47 is 371 hp engine. We can provide you genuine, OEM and aftermarket engine parts with good price and professional service. Better you can provide us the engine nameplate before ordering parts. Taking SINOTRUK for example, with the updating for HOWO trucks year by year, there are many old type spare parts are instead by new types, but the catalog which we use is always cannot keep same step with new trucks. That is why some customer complains that why they cannot get correct HOWO parts since they give part number according to the catalog, so here now we would like to give some advice for dealers, which can help them to prepare the spare parts easily.
