HY linear shaker - food, medicine, chemical industry gridiron

 HY series linear vibrating screen dual vibration motors. When two vibrating motors to synchronize and reverse rotation, the eccentric excitation force generated cancel each other out in the direction parallel to the axis of the motor, the motor shaft in the direction of a force in a vertical stack, and therefore the trajectory of the screening machine a straight line. Two motor axis relative to the screen surface with a dip in the vertical direction, at the joint effect of the exciting force and material self-gravity of the material being thrown forward in a straight line or jump the screen surface, so as to achieve the purpose of screening and classification of materials . Suitable granularity in 0.074-5mm, containing less than 7%, a variety of screening a dry powder or granular material non-tacky. HY-type linear vibrating screen work is characterized by high screening accuracy of the product, the amount of processing the east, simple structure, low energy consumption, low noise, long screen life, sealing, no dust, easy maintenance and can be used in the pipeline production automation. Linear vibrating screen is mainly used in industry, the products are widely applied screening chemicals, food, plastics, pharmaceuticals, metallurgy, glass, building materials, food, fertilizers, abrasives, ceramics and other industries in the dry powder materials. Linear vibrating sieve principle material from the feeder into the screening machine feed inlet uniformly in vibration motor excitation, while beating side screening direction to the discharge port, through multi-screen screening out several product and failed sieve, sieve material were discharged from their exports, inflow silo or filled cartridge. do food to 304 food-grade material health not pollute guaranteed! The basic principles of linear vibrating screen system installed by the lower end of the motor shaft hammer (rough Heng hammer), the rotary motion of the motor into a horizontal, vertical, inclined three million campaign, then the campaign to convey to the screen surface. If you change the weight of the upper and lower portions of the phase angle can change the direction of travel of the raw material. Vibration motor environment requirements: This series motor under the following conditions, continuous rated output excitation force. 1, the vibration acceleration: no more than 7g (g: acceleration of gravity) 2, ambient temperature: not exceeding 40 ℃ 3, Altitude: not exceed 1000m 4, power frequency: 50Hz 5, voltage: 380V 6, temperature: less than 80K (resistance France) five vibrating screen structure and function of each part Description The machine is made of stainless steel sieve screen box, screen frame, stainless steel mesh, vibration motor, motor pedestal, damping spring, and so on. 1, the screen box: the number of different thicknesses of welded steel plate, with a certain strength and stiffness, is a major component of the screening machine. 2, the screen frame: a small wood made of pine or the amount of deformation is mainly used to keep the screen flat to normal screening, can also be used instead of stainless steel grid! 3, Screen: low carbon steel, brass, bronze, stainless steel wire mesh and several kinds. 4, the vibration motor (use and maintenance methods are detailed in the vibration motor instructions). 5, motor pedestal: Install vibration motor, connecting screws must be tightened before use, especially the trial three days before the new screening machine, must be repeated fastening, so as not to loose causing the accident. 6, damping spring: to prevent vibration transmitted to the ground, while supporting the full weight of the screen box, during installation, the spring must be perpendicular to the ground. 7, stand: the four pillars and two channel composition, supporting screen box, the installation must be perpendicular to the ground pillars, the two pillars of the following channels should be parallel to each other. Sixth, the preparation before the installation of a vibrating screen, check the motor plate is consistent with the requirements. 2, with a 500-volt megohmmeter to measure the insulation resistance of the stator winding its value should be dried, the drying temperature must not exceed 120 ℃. 3. Check the motor fasteners, beware loose. 4. Check motor surface for damage and deformation. 5. Check whether the rotating flexible, if unusual, should be excluded. 6, check the power, if phase, and no-load operation for 5 minutes. Seven, installation and adjustment 1, the motor should be fastened to the mounting surface, the mounting surface must be smooth and flat. 2, the motor can be installed horizontally. 3, motor leads with four rubber cable YZ-500V, when connected to the power lead cable does not allow emergency off, and with the vibrator firmly secured. 4, the motor should be reliable grounding, grounding means the motor, there are signs of lead terminals, can take advantage of foot solid grounding bolt. 5, the exciting force adjustment.
