an overview,
fs1000d laboratory high speed dispersing machine is a new high performance product developed by qi wei instrument according to the development trend of international advanced dispersing equipment. the equipment integrates the function of dispersion and agitation, and the two processes of dispersion and homogenization are completed by a machine and a container. high efficiency, good mixing effect and easy cleaning. manual lifting is simple and convenient. it is widely used in dispersing and mixing materials in liquids such as factories, scientific research institutions, colleges and universities and medical institutions.
working principle
this equipment adopts electronic constant force speed regulating line, digital direct display rotating shaft speed, and is equipped with dispersing impeller and abrasive disc. it can adapt to different test requirements of the laboratory, and can provide correct process data for mass production according to the relation between the speed of rotating shaft, material viscosity and chemical reaction rate.
driven by the high speed of motor, the dispersing head of the machine produces high speed of rotary tangential line. under the action of huge centrifugal force, the material produces strong hydraulic shear and high frequency mechanical effect, which makes the fluid material bear thousands of shear and high frequency mechanical effect per minute, thus achieving efficiency mixing, dispersing and homogeneous effect.

scope of application and main technical parameters
this machine is suitable for testing liquid material in container.
the main technical parameters are as follows:
40 kg net weight:
main structure
the machine is mainly composed of the following parts:
1, motor
2. intelligent motor speed control instrument
3. stainless steel barrel
4. lifting support.
5. disperse, sand grinding head
five, the installation
1. fix the two clamps on the rack, and fix the stainless steel cylinder.
2. connect the motor with the five-core aviation plug on the governor. (note the notch direction)
3. connect the ground wire
vi. use and maintenance
1. fix the selected abrasive disc or dispersed impeller with the rotating shaft when using.
2. adjust the high position of the rotating shaft and capacity, lock the motor seat and container, put the materials and cover the container.
3. turn on the power, turn on the switch, wait for the display to reset to zero, and then press the touch button to increase or decrease as required.
4. the motor is a series motor, and sparks are generated when the brush is turned. it is not suitable for the explosion-proof workshop.
5. if the rotating speed is greater than 4000r/min, it is not suitable to open the air compressor.
6. when the motor brush is smaller than 10mm, it should be replaced.
instructions of intelligent motor speed control system
intelligent motor speed control instrument
intelligent motor speed controller adopts intelligent control technology to realize stepless speed regulation of series connected motor. using digital pid technology, high control accuracy, simple system structure, stable and reliable.
main technical indexes:
1. power supply voltage ac220v/50hz
2. control range: 100-8000r/min
3. measurement resolution: 10r/m
4. control accuracy
5. transition time :<8s
6. set speed step :100r/min
7. applicable motor power: less than or equal to 1.1kw
case shape :195 width x 70 height x 175 depth. the control system and the motor (mechanical part) are separated from each other, and the two parts are connected by a five-core cable. the rear board of the case is a five-core socket and input/output fuse, and each pin of the five-core socket is defined as: 1, 2, 3 connected photoelectric sensor: 4, 5 -- connected series motor. the other end of the five-core cable is the photoelectric sensor. when the cable is connected, connect two empty leads at the same end of the photoelectric sensor with the motor lead, plug in the five-core socket on the rear board of the case, and the power supply can be connected for normal use.
operation instructions:
1. turn on the power supply, turn on the power switch, and the indicator on the power switch is on:
2. the system self-checks and the display window is displayed from "9" to "0". after the self-check is normal, the motor speed can be adjusted according to two operations on the panel.
3. press the "up" or "down" button, and the window displays the setting speed value.
motor rotation changes in real time. when the setting value reaches the required motor speed, stop operating the keyboard, and the measured motor speed value will be displayed in the window 2 seconds later:
4. when the test is stopped, press "lower" button to gradually reduce the set speed value to "0", the motor will stop running slowly, or the power switch can be turned off directly.
note: the five-core socket at the back of the controller should be plugged and unplugged after power off.
common faults and troubleshooting:
1. no display on the panel: if the motor switch indicator is not on, please check whether the power supply is normal.
2. the motor does not turn: the output fuse (5a) is broken, please replace it by yourself: if the output fuse is frequently burned, please check whether the motor load is too heavy, and whether the rotating parts are stuck or not, and remove it.
3. the motor speed automatically rises to the maximum and cannot be controlled: first, check whether the gap of the photoelectric sensor is too large: if the fault cannot be cleared after the above inspection, remove the photoelectric sensor, observe whether there is too much dust in the sensor groove, and re-install it correctly after proper cleaning.
4. unstable rotating speed, too big fluctuation: firstly, check whether the supply voltage is relatively stable; whether the motor load fluctuates too much; whether the stirring head is empty; slowly rotate the speed measuring plate by hand for a week; observe whether the gap between the speed plate and the photoelectric sensor is even.
