Backwashing of the filter pool in the waterworks
The backwashing of the filter was an operation process in which the reverse flow of water was used to wash the filter layer to restore the normal operation of the filter. After the filter tank works for a period of time, there will be a situation where the trapped contamination will penetrate the filter layer and cause the water quality to deteriorate rapidly, or the filter layer's filtering resistance will increase to exceed the maximum permitted resistance. At this time, it is necessary to use the bottom-up reverse water flow to wash the filter layer, so that the filter layer can regenerate and the filter can work normally again. Different types of filter tanks have different backwashing intensity and backwashing time. For example, the backwashing intensity of an ordinary fast filter tank is 10 - 15 L/(s·m2), and the backwashing time is 5 - 10 minutes. The V-shaped filter was a new type of filter. During backwashing, the surface of the V-shaped groove was also swept. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Pre-filter, commercial backwashing
How about Midea's backwashing filter?
Midea's pre-filter had many models and had certain advantages. There were a variety of models, including high-end and low-end products, and the price was mostly less than 1,000 yuan. For example, there was a model with a flow rate of 7T/h and a filter precision of 40 millimeters. There was also a household whole house tap water filter, water purifier, Galaxy water power backwashing, automatic scraping, super 8T, large flux, automatic cleaning, QZBW20S-11S, with dual drive water power, automatic scraping and washing 3000 revolutions, every minute hurricane washing, 6T large flux, fast water output, instant filtering, can meet the water needs of the whole family, suitable for flat floors and villas, and life-long free filter. In terms of flushing function, some models have automatic backflushing function. The advantage of automatic flushing is convenience. It can automatically flush and discharge according to the cycle and time set by the user without manual intervention, saving time and reducing the risk of forgetting to clean the filter. However, you should also consider your own needs when choosing. For example, if you want to install an automatic flushing filter, you need to reserve a socket at the installation place.(If you forget to reserve a socket, you can choose a pre-filter that doesn't require power or supports multiple charging methods.) The price may be higher than the manual flushing, but under normal use and maintenance, the automatic and manual flushing pre-filter's filtering effect is almost the same. Both use 40-millimeter filtering precision, and the probability of intercepting large particles can reach 98.57%. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The structure and bearing strength of the backwashing filter cap in Liao Ning
The backwashing filter cap is usually made of ABS engineering plastic, and the structure has many characteristics. The filter head structure has strengthened threads and added rubber cushions to make the connection firm and not easy to fall off. The base of the filter head was designed to strengthen the bottom gap, so that there was no dead water between the filter head and the filter plate, and no mud would accumulate. It has high bearing strength and cannot be broken when stepped on. It can effectively play a role in the backwashing device of the water distribution system at the bottom of the filter tank, which can not only prevent the yin and yang resin from flowing out, but also ensure the flow. This filter cap was widely used in water treatment filter, filter pool, softened water combination, loop, ion exchange column equipment and many other scenarios.

Reflection and summary on the course of heating engineering in university
The following is a summary and reflection example of the university heating engineering course: ** 1. Course summary ** 1. ** Knowledge System ** - Heat supply engineering covered many aspects of knowledge from basic theory to practical application. In terms of basic theory, thermal engineering, fluid mechanics, and other knowledge were the cornerstone to understand the operation principle of the heating system. For example, the heat transfer methods in thermal engineering (transmission, circulation, radiation) were ubiquitous in heating systems. Whether it was the heat generation in the boiler or the heat transmission in the pipeline, it involved the comprehensive effect of these heat transfer methods. Fluid mechanics knowledge helped us understand the flow law of hot water or steam in the pipeline, including the concepts of flow rate, flow rate, pressure loss, etc. This was crucial for the rational design of the diameter of the heating pipeline and the selection of suitable equipment such as the pump. - His professional knowledge included the various components of the heating system, such as the boiler and boiler room equipment, the design of the pipe network in the heating project, and the selection of heating equipment. By learning the structure, working principle, thermal efficiency, and other knowledge of the boiler, one could understand how to choose a boiler suitable for different sizes and needs. For the heating network, master its layout form (branch network, ring network, etc.) and hydraulic calculation method to ensure that the heating demand is met while reducing construction and operation costs. 2. ** Course Practice ** - The course design is an important practical part of the course of heating engineering. In the course design, the comprehensive application of the knowledge learned was used to design the heating system. For example, from determining the heat load to selecting heating equipment, calculating the pipe network diameter, and calculating the hydraulic balance. Through this process, one could understand the relationship between the various parts of the heating system and improve their ability to solve practical problems. At the same time, there would be many problems in practice, such as how to choose the best plan from a variety of design plans, how to deal with various specifications in the design process, etc. - The experimental course also helped to deepen the understanding of heating engineering knowledge. For example, the thermal measurement experiment could further master the use of relevant instruments by measuring the temperature, pressure, flow rate, and other parameters in the heating system. It could also have a more intuitive understanding of the actual operating state of the heating system. 3. ** Skill Upgrade ** - In terms of software application, it might involve some software for heating system simulation and design, which would help improve the efficiency and accuracy of the design. For example, the software could be used to calculate the water pressure of the pipe network. It could quickly obtain the pressure loss and other parameters under different pipe diameter and different flow rates, which was convenient for the optimization of the design plan. - Teamwork skills were trained in practical aspects such as curriculum design. When the team worked together to design the course, the members needed to divide the work and work together. Each of them was responsible for different parts, such as heat load calculation, equipment selection, etc. Then, they would jointly integrate the plan and carry out optimization. ** 2. Course Reflection ** 1. ** Inadequacies in the learning process ** - In terms of theoretical learning, he was not familiar enough with the understanding and application of some complicated theoretical formulas. For example, in the hydraulic calculation of the heating network, some complicated hydraulic calculation formulas were prone to errors in practical application, which reflected the lack of understanding of the physical meaning behind the formula. - In the course practice, although he participated in the course design, he lacked innovative thinking in the design process. They were often limited to traditional design methods and ideas, and did not fully consider the application of some new technologies and concepts in heating projects, such as the use of new energy in heating, the design of intelligent heating systems, etc. 2. ** Teaching suggestions ** - In the teaching content, some practical engineering case analysis could be added. By analyzing the successful experiences and failures in practical engineering, students could better integrate theoretical knowledge with practical applications and improve their ability to solve practical problems. - In terms of teaching methods, more interaction could be added. For example, organizing class discussions, allowing students to propose their own solutions to a heating project problem and evaluate each other. This could stimulate the students 'enthusiasm and initiative in learning, and at the same time, it would also help to cultivate the students' critical thinking ability. - In terms of practical teaching, they could further strengthen their cooperation with enterprises. Arrange for students to practice in heating companies, so that students can understand the actual operation and management of heating projects in a real working environment, which is very helpful for improving the competitiveness of students in employment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is backwashing in filtering?
During the filtering process, as the suspended substances and particles in the sewage were captured by the filter media, dirt and impurities would gradually accumulate on the filter media, resulting in a decrease in the filtering efficiency, an increase in head loss, a deterioration in water quality, and possible occurrence of an anaerobic decay phenomenon. Backwashing was an operation to solve these problems. It was a high-speed water flow washing process in the opposite direction of gravity flow filtering. The purpose of backwashing is to remove the dirt and impurities on the filter media to maintain the filtering efficiency, extend the service life of the filter media, restore the working performance of the filter, restore the dirt holding capacity of the filter material layer, and avoid the occurrence of the phenomenon of oxygen decay. There are several backwashing methods commonly used in the particle filter bed: 1. After the filter material was flushed into a suspended state, the suspended matter was washed down by the high-speed water flow between the filter materials and carried away by the backwashing water. 2. Backwash with water to assist with surface rinsing. The surface washing water is on the filter layer, and the washing water is sprayed out from the spray mouth, so that the sand grains are well stirred, so that the suspended matter is easier to fall off, and the washing water can be saved at the same time. 3. Backwash with water to assist with air scrubbing. Usually, before the start of the water backwashing cycle, compressed air was introduced to stir the filter material. At the same time, the suspended matter was washed away by backwashing water, which could save the amount of washing water. 4. The combined air-water flushing method was mostly used in single-layer filter beds. In addition, when to carry out backwashing can be determined according to the water quality characteristics of the raw water and the requirements of the water quality of the discharged water, using standards such as limiting the head loss, the quality of the discharged water, or the time of filtering. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Backwashing Steps of the Lube Oil Cooler
The backwashing steps of the oil cooler are as follows: First, close the oil cooler's valve at the entrance and exit, open the oil cooler's drain valve, and discharge the sewage. Then, open the oil cooler's backwashing valve, inject the cleaning fluid into the oil cooler, and maintain a certain pressure to make the cleaning fluid circulate inside the oil cooler. Next, if necessary, a high-pressure water gun could be used to rinse the oil cooler to remove the dirt. Finally, close the backwashing valve of the oil cooler, open the valve at the entrance and exit, and discharge the cleaning liquid to complete the backwashing of the oil cooler. There was also an oil cooler backwashing procedure: (1) Close the throttle first, then slowly open the entrance throttle and the top vent valve, filling the oil side with oil. Close the air vent valve when oil flows out, then open the outlet throttle and pay attention to the change of oil pressure;(2) Open the oil cooler's entrance water gate, slightly open the air vent valve at the side of the water cooler, and then close it after exhausting the air. He slowly opened the water gate. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
