According to the requirements of the latest national standard GB/T5507-2008 "Measurement of grain and oil inspection powder thickness," YFS30x8 new national standard powder screening screen independently developed and produced by Top Instrument has been launched. The principle is that the sample is sieved on screens of different specifications, the samples of different particles are separated from each other, and the thickness of the grain is calculated according to the residue amount on the sieve. The circular powder screening screen has many structural advantages. Specifically, the structure adopts a worm gear with a stable center of gravity and high precision as a variable speed transmission, and the eccentric linkage mechanism performs a plane rotation motion, and the tray integrally presses against the rod seat. The sieve is fixed more firmly. In addition, the circular powder screening adopts single-chip microcomputer control, electronic timer controlled by a single-chip microcomputer, high timing precision, easy operation, and can realize various functions such as time setting, working time, emergency stop and automatic zero reset. The technical indicators of the new standard powder screening are in full compliance with the requirements of the new GB/T5507-2008 national standard. They are the product quality inspection institutes of grain and oil, the quality and technical supervision bureaus, and grain processing plants that measure the fineness of powders. Essential testing equipment.
Coalescence &Separation Filter Elements
Describe:
The coalescence separation filter element is generally cylindrical in shape, and the coalescence separation filter element is used in the oil-water separation system, mainly separating the oil-water mixture, suspension solution, emulsion solution, etc. The application flow of coalescence separation filter in the system can be divided into solid-liquid separation-demulsification-coalescence-separation. In the system, the number of Coalescence Filter and separation filter is better than that of 3:1, the effect of coalescence is good and the separation speed is fast.
Principle and characteristics:
The surface treated glass fiber or polyester fiber is mainly used as the coalescence medium. The structure of the Filter Material is 0.1 μ m by special design. The filter medium has good coalescence performance. Working process: after the emulsified oil enters the coalescence separator, it first enters the inner filter core from inside to outside, and the small liquid droplet in the dispersed phase changes from small to large. Finally, it falls off on the surface of the coalescence filter core and completes the coalescence process. In the process of flow separation, the larger water drops sink into the sink by gravity, and the small water droplets flow along with the oil to separate the filter elements. The separation filter has hydrophilic effect to block the passage of water. Small water beads collide to form large water droplets, which then settle into the sink again, thus dehydrating the oil.
Different packing sizes should be selected according to different oil-water systems: the smaller the packing size, the larger the specific surface area per unit mass and the larger the contact area with droplets. As a result, the performance of the coalescence filter element is enhanced. Therefore, it is suggested that the separation efficiency of coalescence filter should be taken into account when choosing fiber size, and the pressure drop should be taken into account at the same time.
Range of applications
