With the accelerated upgrading of the color TV industry, 4K TVs and HDR TVs have become the dominant products in the color TV market. However, for a lot of ordinary consumers, 4K, HDR and other very professional vocabularies do not seem to be very understanding, but also lead to many consumers are confused by the sales staff flickered. Today, I will take everyone with science and technology what is HDR and true 4K display technology? 
What is HDR display technology?
HDR (High-Dynamic Range) translated as "High Dynamic Range Display Technology", the term originally referred to people still in the field of photography, it is a photo enhancement techniques capable of dynamic range, which is the brightest white and the darkest The contrast between black. For example, many smart phones support HDR shooting. They can take multiple photos of different exposures and synthesize them using HDR technology. HDR-combined photos have higher definition and stronger sense of hierarchy.
First of all, support for HDR display devices has a wider dynamic range, so that a variety of different brightness can be completely presented. HDR-enabled TVs have a higher dynamic range than ordinary TVs. Dynamic range refers to the highest overall contrast that can be found in an image.
Usually we use a ratio, such as "200:1", "400:1", etc. This value depends on the full range of brightness and the minimum brightness level. Obviously, the greater the dynamic range, the better the display contrast and color accuracy. The most intuitive feeling is that it looks like the image is displayed more clearly, the sense of depth is stronger, and the colors are more abundant.
What is 4K resolution?
The 4K resolution means that the pixel value of each line in the horizontal direction reaches or approaches 4096, and in most cases it specifically refers to a resolution of 4096*2160. Depending on the range of use, there are a variety of resolution 4K resolution derived, e.g. Full Aperture 4K is 4096 * 3112, Academy 4K 3656 and 2664 * 3840 * 2160 UHDTV standard, all belong to 4K resolution category.
4K, with a new generation of Hollywood block resolution standards. It differs from the so-called high-definition TVs we see at home, and also differs from the traditional 2K-resolution large-screen digital cinema screens, but with an ultra-fine picture with 4096×2160 resolution. Traditional high-definition television is a 2.07-megapixel screen, and in a traditional digital cinema, it is a 2.21-megapixel screen. In a 4K theater, it can see a high-definition screen of 8.85 million pixels.
The standardized 4K (3840 horizontal pixels) can reach 4 times the HD resolution. At this resolution, the viewer will be able to see every detail in the picture, every close-up. With bright colors and super-real sound effects, the audience can enjoy a great viewing experience.

Since the modern mud (or slush) pump was built approximately 60 years ago, the industry has widely accepted the three cylinder or triplex style pump. Triplex mud pumps are manufactured worldwide, and many companies have emulated the original design and developed an improved form of the triplex pump in the past decade.
As in all single acting pumps, the piston exerts a load on the crankshaft. The load is then transmitted to the crankshaft main bearings, which are set in their retainers in the pump frame or housing.
