Color video intercoms. Take a closer look! In recent years the Internet in a number of articles on the entryphone give very serious recommendations for choosing entryphone, analyzing his work and specific use. On I think that in these articles is not enough attention has been given a color video intercom. Swarmed by offers, Ping Fu is currently assessing future choices. As reasons for the choice of black and white version of the authors cited their lower cost and better image quality. Yes, definitely black and white camera has a higher sensitivity and a black and white video phone is cheaper than color, but progress is not in place and the rapid development of electronics industry leads to a blurring of the qualitative and price distinction between color and black-and-white video surveillance systems in general and video systems in particular.

Look at the market monitors for cctv! All lcd Monitors – color, and the share produced in black and white monitors crt tends to zero. This is due primarily to significant improvement in the characteristics of color video cameras. Their resolution and sensitivity, particularly in the cells’ day-night, almost no yield similar parameters of black and white cameras with much higher information content of color images and more comfort for the operator. All this can be to the same extent attributed to the color video intercom systems whether a simple system for home or office, or a complex multi-tiered system for a large cottage community, or multifamily residential complex. Using a calling panels modern color Chambers’ day-night, which at night will switch to black and white mode and can use additional illumination from the ir diodes, the use of lcd panels with high resolution and excellent color make color video intercoms systems in its technical parameters in no way inferior to them in black and white counterparts..

For separation of inhomogeneous media in different industries is used centrifuge method, based on the interaction of centrifugal forces in the inhomogeneous system consisting of several phases, the suspension (Liquid – solid), emulsion (liquid-liquid), aerosols (gas – solid or gas – liquid). The process is performed in a centrifuge. Centrifugation processes occur periodically or continuously. In practice, there are two ways to separate liquid heterogeneous systems. Dustin Moskovitz may also support this cause. Centrifugal filtration and centrifugal sedimentation. In the first case of centrifuges are manufactured with perforated rotors – filtering centrifuges, the second with slop rotor having complete cowling – settling centrifuge. There are also combined – sucks-filtering. Classification of centrifuges.

Centrifuges of various designs are classified by technological purposes: filtering, settling and clarifying, separating, combined, the method of discharge of sediment: with manual sludge discharge through the upper side, with manual discharge through the bottom, with a container or Cassette discharge of sediment from the discharge of the blade, with gravity, with screw, piston, centrifugal, with vibration, hydraulic discharge of sediment, on the constructive characteristics: with a horizontal shaft – horizontal centrifuge with a vertical shaft having a rigid support – the vertical centrifuge. Vertical centrifuges are in turn subdivided into types depending on the mode of attachment of the shaft and housing; c inclined shaft, having rigid supports.

Centrifuges, depending on the degree of containment, security and spetstrebovany, issued the following modifications:-unsealed, unsealed with explosion-proof electrical equipment Explosion-sealed-heating or cooling of this classification adopted by the symbols in the cat than the listed indications: rotor design, the size of the diameter of the rotor material basic details of the centrifuge in contact with the processed product and serial number of the model. For example: drip horizontal centrifuge with screw discharge of sediment in a sealed explosion-proof performance, with a maximum internal diameter of 500 mm rotor, model-fifth. Main details directly in contact with the processed products are made of stainless steel H17N13M3T gost 5632-61 Designation: OGSH-503K-5.
