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%. Read more exciting novels for free
How does Midea's backwashing pre-filter backflush?
Midea's backwashing pre-filter backwashing steps were as follows: First, find the rotating button on the filter and turn it three times counterclockwise; then, find the drainage button and turn it 90 degrees; then, open the drain valve at the lower end of the filter and wait for 20 seconds before starting the backwashing; after the rinsing was completed, turn the knob three times to reset. At this time, the drain ball valve stayed for 20 seconds before turning the drain button to close the drain ball valve, restoring the normal water use state, and completing the filter backwashing. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Pre-filter, commercial backwashing
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>
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>
Gree questioned Midea's fraud. It was suspected that Chongqing Midea's receipt information was inconsistent. What was the truth of the incident?
As far as I know, Gree recently suspected that Midea was suspected of fraud in the aspect of the receipt and found some inconsistent information in the receipt of the suspected Chongqing Midea. This incident attracted widespread attention and caused the relevant departments to intervene and investigate. After investigation, it was found that there was indeed some evidence that Chongqing Midea had violated the rules in terms of the receipt. It was reported that in some cases, Midea in Chongqing had used the actual production of the wrong kind of receipt to cheat the state of tax revenue. The truth of this incident still needed more details and investigations to be determined. However, Gree's questioning and investigation attracted the attention and support of many people. Many people believe that it is illegal to cheat the country of tax revenue through false payments and that it will have a negative impact on society as a whole. The relevant departments are working hard to investigate this incident and ensure that all evidence is properly handled and preserved.

Reflection on the Midea supplier incident
In June 2020, Midea's supplier incident happened. It was rumored that the supplier had broken into the residence of Midea Group's founder He Xiangjian to make trouble because of long-term settlement and loan usury. However, Midea Group's official Weibo said that someone deliberately fabricated the facts and reserved the right to pursue legal responsibility. From this incident, one could reflect on the following aspects: ** I. Relationship between enterprises and suppliers ** 1. ** Foundation of Trust and Cooperation ** - In the business ecosystem, the relationship between companies and suppliers should be based on trust. If the supplier really faced long-term settlement difficulties, it would seriously affect the trust relationship between the two parties, which might affect the stability of the entire supply chain. For example, if the supplier was unable to provide high-quality raw materials or parts on time due to cash flow problems, it might cause problems such as production delays and product quality decline. - The company needed to plan the cooperation model with the supplier reasonably to ensure that the terms such as the settlement cycle were clear, reasonable, and sustainable to avoid similar conflicts. 2. ** Corporation's social responsibility ** - From a supplier's point of view, if the harsh conditions of the supplier were true, it might imply that the company neglected its social responsibility to the supplier in the process of pursuing its own profit. The company should recognize that the supplier is an important part of the industrial chain. Helping the supplier to operate stably is also a guarantee for the company's sustainable development. - For large enterprises, they should play an active leading and supporting role in the entire supply chain to ensure that suppliers can operate within a reasonable profit margin and promote the healthy development of the entire industrial ecosystem. ** 2. Public opinion response and corporate image ** 1. ** Information Dissemination and Truthfulness ** - In the current era of social media, information spread very quickly and was easily distorted. The rumors in the Midea supplier incident could spread quickly, indicating that companies needed to pay more attention to public opinion monitoring and response. The company should establish a rapid response mechanism. Once false information is discovered, an official statement should be issued in time to clarify the facts, so as to prevent further spread of false information and cause greater damage to the corporate image. 2. ** Maintaining corporate image ** - Although the incident was officially declared a rumor, it was undeniable that it had a certain impact on Midea's corporate image during the spread of the incident. The corporate image was the intangible asset of the enterprise. The enterprise needed to pay attention to the shaping of its own image in its daily operations, including the positive publicity of the relationship with the supplier and the fulfillment of corporate social responsibility, so as to enhance the ability of the enterprise to withstand the pressure in the face of similar public opinion crises. <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.
