An open impeller has vanes that are attached to a center hub and mounted directly onto a shaft. There is no wall surrounding the vanes which makes open impellers weaker than closed or semi-closed valves. Open impellers are generally faster and easier to clean and repair. Centrifugal pump impellers are selected with purpose and are dependent upon the application. Some are better for solids handling, others are better for high efficiency.

In the face of mass television products and complicated technical terms, consumers are often at a loss when shopping. Some shopping guides who verbally inaccurate or even irresponsibly exaggerate their promotion will undoubtedly mislead consumers who are “outsidersâ€. The May Day holiday will soon come. New products and promotions will be on the market. Many friends will choose to purchase TV products at this time. Like 2K to 4K, blue eyes, artificial intelligence, VR/AR... How do we face up to a lot of new technologies? Following the author for everyone to popularize, let you dare to face the Purchasing Guide.
2K to 4K This technology is also eager to come up with it?
At present, 4K ultra-high-definition television has been basically popularized in the market, but many people worry about buying a 4K TV but can't enjoy 4K picture quality, and relatively scarce 4K source is still the biggest pain point in the hearts of users. In response to this problem, a technology called 2K to 4K came into being. Many manufacturers also claim that this technology can make high-definition film sources show comparable 4K image quality performance. How are various technologies implemented? Is this really the case? 
LCD or OLED should be how to choose?
From the perspective of the development of display technology, OLED TVs are gradually emerging and there seems to be a trend to replace mainstream LCD TVs. The advantages of OLED are mainly reflected in the following aspects. First of all, OLEDs are self-illuminating, unlike LCDs, which require backlights. The quality of the picture reflects the outstanding performance of the OLED black field and the perfect black display. We all know that the LCD itself does not emit light and needs the support of the backlight. Leakage is unavoidable and can not show true black. 
Artificial intelligence flying sky VR TV what ghost?
The term "artificial intelligence" may not be unfamiliar to us. With the great stride of the Internet era, more intelligent and humanized product concepts have been brought to the table by manufacturers. Artificial intelligence television generally refers to artificial intelligence technology and home television connection. Through perfect technical logic and big data operation, TV has language recognition, image recognition, natural language processing and expert system. Through the use of voice commands, TVs can automatically recommend and select TV products. At the same time, they can also learn user usage and search habits to achieve more precise voice control and interaction. 
What ghosts are VR TVs? Just a gimmick VR technology has swept the world in the past two years. As a black technology, many people are full of curiosity. Many TV manufacturers have joined the R & D camp, and domestic production of VR TV products. In fact, the so-called VR TV is just a simple projection technology. It connects the mobile phone to the TV through the local area network. After the connection, the perspective of the TV will change following the rotation of the mobile phone. The contents of the mobile phone display will be displayed on the screen of the TV. After placing the phone in the VR headset and wearing it, the TV screen will display what people see in the VR to achieve a so-called 720-degree panoramic landscape experience. 
In fact, to purchase TV products, the most important thing is from the appearance, quality, system content, these touched, visible point of view, when buying must have their own opinions, a thousand people in the eyes of a thousand Hamlet You think a TV is of good quality.

LCD actually sold when OLED? 51 TV market pit prevention guide
For consumers, how to have a pair of eye-catching eyes, when the TV is not being overwhelmed by the overwhelming publicity of the manufacturers, but also become the most troublesome thing for consumers. Close to May Day, after a period of silence, the TV market has gradually become fiery. New television companies have made new products and many new technologies have been put on the table. However, some unscrupulous merchants often create new terms on their own, making their products look even taller, and even worse, they even sell LCD TVs as OLED TVs. What should we choose for a wide array of TV products? Written at the end;
51 TV market pit prevention guide
Some friends may have questions, how can a formal appliance store steal the column? Moreover, OLED TV prices are much higher than ordinary LCD TVs. Whoever has such a big courage dares to do so. Say you may not believe, I have personally experienced this kind of thing. In the beginning, the Purchasing Guide will introduce consumers to a certain LCD TV and use some product features unique to OLED TVs to describe them: Self-luminous, high contrast, and ultra-fast response speed..... Although not stated on the surface, This misleading introduction will often allow consumers to pay for it at a very high price. TV market presents a hot scene during the holiday season
Often in some supermarkets that appear to be honest and reliable, and sometimes for profit, some shopping guides will lay down layers of consumption traps. They often use "misleading concepts", "misleading promotions" and other means to paralyse consumers and allow them to sell out. *. And it is precisely on some seemingly tall, dazzling technical terms that allow some businesses to find a way out. 2K to 4K technology is claimed to be comparable to 4K quality
The 2K to 4K technology currently on the market is mainly implemented in two ways: a single compensation technology and an associated compensation technology. The first one is calculated by an image processor mounted on a 4K TV, and performs tracking compensation and rendering for the movie being played. Simply speaking, four pixels are directly inserted into each pixel, so that the 2K resolution can reach 4K in numerical value, but this will cause the original details to be lost, and the overall improvement is not significant. 2K to 4K technology
The second technique directly analyzes the video signal in real time and divides the entire screen in the screen into 2 million equivalent partitions. After performing vertical and horizontal four-dimension color operations on adjacent segments, the second pixel is inserted into the pixel and calculated. , Estimate the color of the surrounding pixels and quickly fill it to simulate the effect of 4K screen. There is a gap between the actual effect and the real 4K picture quality
At present, this technology only improves the quality of the movie to a certain extent, and there is still a big gap between it and the real 4K source, and the lack of a good processing chip to increase the resolution alone can only make the screen become a piece of paper. You may not even know that 2K to 4K technology has already been added to the 4K Ultra HD TV purchase standard, which means that currently 4K TV products on the market should have this technology, so you don't have to deal with the rants when you purchase. Compared to LCD panel OLED structure is simpler
Structural differences allow OLEDs to be thinner than LCD screens. Because there is no backlight component, the OLED screen structure is simpler. At present, the thinnest OLED TV product on the market, the LG Signature printed G6 TV has reached 2.57mm. With the continuous advancement of technology, this limit will continue to be broken. Maybe it can evolve into a single piece of paper. OLED screens also have flexible and bendable features that allow more viable scenarios for TV morphological changes. OLED black field performance outstanding
So is OLED the only choice? The answer must be negative. Compared with the shortcomings of OLED TVs such as burn-in and short life, LCD TVs have been developed for more than ten years, and their lifespan and stability are undoubted. Their malleability is strong and they are unprecedentedly high, leaving many TV manufacturers unwilling to give up. . The price of OLED TV has been high, the minimum price has to exceed 10,000 yuan, while the ordinary large-screen LCD TV is cheap, more cost-effective. Large-size high-end OLED TVs are often expensive
When choosing, you don’t have to worry about which one to choose. According to your needs, friends who pay attention to high-end picture quality can choose OLED or high-end LCD products, such as Quantum-dot TVs. Users who value everyday performances and can meet the daily viewing needs can purchase one. Ordinary LCD TV is enough. The current artificial intelligence TV is still in its infancy
At present, artificial intelligence angels fly. Judging from the recent TV new product launch conference, many manufacturers have put their own TV products on the "artificial intelligence" label. In fact, they are mainly engaged in some interactions between the user and the TV from voice operation and user habits. There is a certain gap in the sense of artificial intelligence, and can not completely solve the user's use of pain points. VR TV gimmicks are larger than practical
Users watch through their VR headsets, and others watch your main perspective on TV. It seems that VR TV is quite awkward. VR itself will have to use the headset, inside or built-in screen, or use a mobile phone instead, who will see a TV screen? This VR+ TV is just a preliminary stage and the two are not well integrated. Shantou is more than practical, consumers can ignore this concept.
