Precautions For Vacuum Emulsifier Operation
Vacuum emulsifier is widely used in cosmetics, food, pharmaceutical and chemical industries, which sets the functions of homogenization, emulsification, mixing and dispersion in one, and is a key equipment for efficient production. This document describes the operation precautions, maintenance methods, and troubleshooting solutions of the vacuum emulsifier to help you use the device safely and efficiently.
Top 13 Operating Precautions for Vacuum Emulsifying Mixer
1. After production, the vacuum emulsifier must be clean, so as to maintain the service life of the stator and rotor and work efficiency and can play a role in protecting the emulsifier seal. If necessary, you can design and install a set of cleaning cycle device in the periphery.
2. Vacuum emulsifier operation if found at the shaft of the liquid leakage phenomenon, it is necessary to adjust the pressure of the seal after the shutdown.
3. Emulsifying machine to confirm the connection of the seal cooling water, start the motor, be sure to ensure that the motor steering and spindle steering signs are consistent with the operation of the work, is strictly prohibited reversal!
4. According to the user to use different materials, the import and export filters must be regularly cleaned to avoid the feed volume to reduce the impact of production efficiency. Into the working cavity of the material must be fluid, do not allow dry powder, lumps of material directly into the machine, otherwise, it is easy to cause boredom and damage to the vacuum emulsifier.
5. Strictly prohibit metal shavings or hard and difficult to break debris into the working chamber of the vacuum emulsifier, in order to stator, rotor and other equipment to cause devastating damage.
6. In the use of vacuum emulsifier before to develop a corresponding safety production operating procedures to ensure the safety of operators and equipment. In the electrical control system users should set up a safety protection system, and have a good and reliable electrical motor grounding device.
7. Vacuum emulsifier process chamber can be equipped with another insulation layer, for the cooling or heating of the material, boot first connected to the coolant or heat transfer oil. Insulation sandwich working pressure ≤ 0.2Mpa, in the processing of temperature requirements must be heated or cooled to the normal working temperature, disk, boot.
8. When the emulsifier is used in flammable and explosive working environment, the corresponding level of explosion-proof motor must be used. You can contact our customer service customized.
9. Usually only through the high level of self-weight to the TRL1 pipeline equipment into the material, the feed must be continuous input to maintain the material has a good fluidity. The poor fluidity of the material, viscosity ≧ 4000CP when the SRH in-line equipment inlet to be equipped with a transfer pump, pumping pressure 0.3Mpa. Selection of pumps should be used in colloidal pumps and the like, the flow rate and the selected in-line emulsifier flow rate range to match.
10. Usually open the vacuum emulsifier before connecting the mechanical seal cooling water, shut down the machine and then cut off the cooling water. Cooling water can be used tap water. The material must enter the working chamber before starting, and to ensure that the material is not broken in the case of running to avoid idling so that the mechanical seals due to high temperature burnt or affect the service life. Cooling water import and export fittings equipped with hose size inside diameter.
11. Vacuum emulsifier should regularly check the stator, rotor, found excessive wear, should be replaced in a timely manner to ensure that the dispersion, emulsification effect.
12. In the use of vacuum emulsifier, liquid materials must be continuously input or in the container to maintain a certain amount. Vacuum emulsifier should be avoided to run empty, so as not to make the material in the work of high temperature or crystallization and solidification and damage to the equipment.
13. Vacuum emulsifier in the process of running once the abnormal sound or other faults, should immediately stop the machine to check, to remove the faults before running. After stopping the machine should be working chamber and the stator, rotor cleaning.
Common faults and solutions
| Failure phenomenon | Possible Causes | Solution |
|---|---|---|
| Uneven emulsification | 1. Wear of homogenizing head 2. Low mixing speed 3. High viscosity of material |
1. Check and replace the homogenizing head 2. Adjust the mixing speed 3. Reduce the viscosity of the material. |
| Vacuum degradation | 1. Vacuum line leakage 2. Vacuum pump oil contamination |
1. Check piping connections 2. Replace vacuum pump oil |
| Leakage at shaft seal | 1. Mechanical seal damage 2. Seal aging |
1. Adjust seal pressure 2. Replace seal ring |
| Discharging difficulty | 1. Pipe clogging 2. High viscosity of the material |
1. Clean the pipeline 2. Change the way of discharging |
By strictly following equipment installation, operation procedures, safety specifications and regular maintenance, the incidence of failure can be effectively reduced, maintenance costs can be reduced, and production stability can be ensured.
