Three energy-saving steam traps and working principle

Posted by uuuseff on November 18th, 2019

Different types of steam traps structure and principle are different, should be different trap type valve, according to the actual use of conditions to determine the steam trap inlet and outlet pressure difference, and then steam heating equipment in normal work may result in condensation Water, multiplied by the choice of correction factor K, and then control the steam trap to choose the amount of displacement. In the condensate recovery system, if the use of working pressure recovery of condensate, should use a higher back pressure steam traps (such as mechanical steam traps); when required steam equipment may not accumulate condensate water should be (Such as Guilong float steam trap); In the condensate recovery system, the steam equipment requires both the discharge of saturated condensate, but also requires the timely removal of non-condensable gases, Should be used to drain saturated water steam trap and exhaust parallel to the drainage device or the use of both drainage and exhaust steam trap valve (such as thermal static steam traps); when the steam equipment work Frequent fluctuations in pressure, the choice should not need to adjust the working pressure of steam traps. At present, there are many types of steam traps, but their working principle is to make use of the difference of the height, temperature and flow rate of steam and condensate water to realize the opening and closing of the steam traps through various mechanisms so as to achieve the purpose of blocking steam drainage. It mainly has three energy-saving effect. First: the rapid discharge of steam using the condensate generated within the equipment, the use of steam heating equipment to maintain the best efficiency, so that the device does not form a stagnant water condensation to maximize the equipment to ensure that the steam space, which can often Maintain the highest heating efficiency. Hongfeng believes that once the steam trap can not fully play its role, due to the retention of condensate, not only the performance of the steam used equipment is greatly affected, and sometimes the production equipment is completely paralyzed. Second: Rapid discharge of air and low temperature condensate from the start of the start-up, shortening the warm-up time. At the beginning of steaming, the steam delivery lines and the steaming equipment are filled with air and if they are not excluded, they can not be fed into the steam. In addition, during the process of steam heating equipment and steam heating equipment to achieve the steam temperature, the initial low temperature condensate generated must also be quickly discharged, so that the equipment to achieve normal operation in a short period of time, which is an important condition to improve production efficiency, Especially in intermittent production, shortening the preheating time reduces the time required for each operation. As a result of the increased number of treatments, it eventually increases the output. In the past, bypass valves were first opened to allow primary air and low-temperature condensate to drain when preheating, and the proper steam traps were now used to automatically drain primary air and initial low temperature condensate as well as save labor. Third: Reduce the steam consumption of steam traps. The so-called steam traps own steam consumption, generally refers to the steam leaks, is the steam trap valve action needs the amount of heat and heat loss.
