I. Introduction cement mortar mixer designed by China Building Materials Academy of cement, the Unified Device national standard "cement mortar strength test method (ISO method) GB / T 17671-1999" provisions applicable to the preparation of cement mortar specimens When mixing, this machine is a cement plant, construction units, relevant professional institutions and research institutes cement necessary laboratory, one of the devices indispensable. Second, the main technical parameters: 1. Mixing blade rotation number two, stirring the pot stirring blade trajectory with IS0679-1989 (E) requirements. 3, a stirring blade width of 135mm. 4, stirring the leaves and mixing blade shaft connecting thread for M 1 8 × 1.5. 5, stirring the pot volume 5L, wall thickness of 1.5mm. 6, the working gap between mixing leaves and stir the pot for 3 ± 1 mm. 7, power is O.55 / O.37kw. 8, Dimensions: length × width × height 600 × 320 × 660 (mm) 9, Weight 70kg three, cement mortar mixer Safety rules Procedure 1. Remove the mixing pot, stirring the pot and stir with Esen wet wipe with a damp cloth, put the pot on the fixed bearing positioning hole pot clockwise to lock, and then move up to the handle so that stirring the pot stirring work positioning location, loaded ISO standard sand bag (1350g) within Shaguan, a good amount of water is added to 225mL pot, adding 450g cement. 2. Immediately start mortar mixer, automatic control procedures: After low speed stirring 30s, automatically adding sand evenly, while the second start of the 30s, high-speed stirring 30s, stop mix 90s, 60s and stirring was continued at high speed and then stopped work program, the whole process 240s, then, move the handle to move down the stirring the pot, stir the pot to loosen counterclockwise rotation position, remove the mixing pot. 3. Manually: the toggle switch to the manual position, the machine that rotates according to the test needs, we can control the low and high speed of rotation time, maintenance and precautions 1. The electrical part of the insulation should be a good start commissioning, observe machines head is shaking leaves and pot if there is friction, with or without abnormal operation, stirring clockwise before commencing normal test automatically and revolution counterclockwise direction around the pot, until everything is normal. 2. Use should be promptly cut off the power supply, carefully cleaned leaves and stir the pot, residual mortar machine, and apply a small amount of oil to prevent corrosion (mechanical transmission parts Oil it serviced once a year). Clear plastic body and work surface sand and dirt, to be kept clean and dry, and record the functioning of the machine. 3. Mixing blade and bottom of the pot, and stir the gap between the wall every time you want to use a self-test once a month. 4. When using stir the pot, to gently, not random collisions, to avoid stirring the pot deformation. Fourth, cement mortar mixer main structure and working principle: 1. Structure: There are two-speed motor, sand box, gearbox, shaft, eccentric seat, stirring leaves, stir the pot, base, column, bearing, housing, programmable and other components. 2, the working principle of a two-speed motor drive power is transmitted through the coupling box and then the worm gear and worm gear and a pair of pass spindle and deceleration. Driven eccentric shaft seat synchronous rotation, so that the eccentric seat fixed mixing blade revolves. While stirring blades complete rotation motion about a fixed axis of the internal gear through the stirring blade end of the planetary gear. Stirring the pot with the bearing with eccentric rotation lock slot, plus sand within Shaguan after automatic or manual sand sand at the specified time, the handle for lifting and positioning by stirring the pot position. Fifth, cement mortar mixer adjustment and maintenance 1, adjustment: the factory, the unit will work leaves stir the pot and stir to adjust the gap between the range of 3 ± 1mm. Mixing blade gap adjustment and work stirring the pot, you can loosen the adjusting nut rotating mixing blade moves up and down so that, after detecting lever then detect the correct gap, and then tighten the adjusting nut (to 2, maintenance: Keep work area clean after each use should be completely removed by stirring the leaves and stir the pot, outside residual mortar, mortar and dirt and cleaning material scattered and splashing on the machine, after wipe dry, put on guard to prevent dust. The machine has no external fuel holes pay worm gear box, gears and bearings and other moving parts to pay quarterly butter once, when refueling, open the lid, the lid can be between the drive, then open the seat rails and columns should be between the lifting mechanism often drip oil lubrication, maintenance once a year, all of the machine cleaning and filling oil and grease. In case of metal impact noise, you should first check the clearance between the stirring blades and stirring the pot is correct when the machine is running. Use agitation When the pot, to gently, not random collisions, stirring the pot in order to avoid distortion should always check the electrical insulation, cold insulation resistance at a temperature of 20 ℃ ± 5 ℃ relative humidity of 50% to 70% when ≥5MΩ. six cement mortar mixer and install a lift, this machine has no lifting equipment, manual handling can be. 2, the machine simply will host installation on a flat concrete platform and a thick mat on the bottom 5 ~ 8mm rubber board seven, cement mortar mixer host structure diagram Hebei Rui Heng Test Instrument, factories twenty years, millions of units of production test equipment, cast-class quality, low price, excellent service.
