How long does a vacuum emulsifier go bad? Pay attention to a few maintenance tips

　　"Pharmaceutical Network Technical Article" vacuum emulsification, refers to the material in the vacuum state, the use of high shear emulsifier quickly and uniformly one phase or multiple phase distribution to another continuous phase, its use of mechanical brought by the strong kinetic energy, so that the material in the narrow gap of the fixed rotor, every minute to withstand hundreds of thousands of hydraulic shear Centrifugal excitate compression impact tear and other integrated effects, instantly evenly dispersed emulsification, through high-frequency cycle back and forth, to obtain bubble-free delicate and stable high-quality products
In the pharmaceutical, cosmetics and other industries, with the market size continues to expand, the requirements become more stringent, the current drug vacuum emulsifier in the protection of high quality of products play an increasingly important role
Industry said, in order to maintain the efficiency of the vacuum emulsifier machine and product quality, but also in order to extend the life of the vacuum emulsifier machine, operators must regulate the daily use and maintenance of the vacuum emulsifier Specifically, the following mainly includes the following
For example, when maintaining electrical equipment, we need to ensure that equipment and electrical control systems are clean and hygienic, do a good job of moisture- and corrosion-proofing, and the inverters should do a good job of ventilation, dust removal and other cooling work Industry reminds that if this is not done well may have a great impact on electrical equipment, or even burn electrical equipment
For example, the safety valve to be regularly checked to prevent the valve rust and dry failure, the trap regular inventory, to prevent the blockage of debris, vacuum system, especially the water ring vacuum pump, in the use process, sometimes because of rust or debris, stuck rotor caused by the motor burned, so in the daily maintenance process to check whether there is a blocking situation;
It is reported that the vacuum emulsifier has a lot of seals, so the mechanical seal to regularly replace the static ring, the cycle depends on the frequent situation of equipment use, two-sided mechanical seal to often check the cooling system, so as not to cool failure burned mechanical seal Skeleton seal, according to the characteristics of the material, choose the appropriate material, and in use according to the maintenance manual regular replacement
In addition, motors, gearboxes, according to the manual regularly change grease, frequent use to check the viscosity and acidity of lubricants in advance, change lubricants in advance
In addition to regular maintenance equipment, it is also necessary for operators to master the failure of the vacuum emulsifier and the method of troubleshooting When the vacuum emulsifier fails during operation, it should be stopped immediately for inspection, pending troubleshooting and then operating In general, common faults in vacuum emulsifiers can be corrected by the following checks
First, check whether the power supply is normal supply, whether there is a place to leak power, whether the motor wind leaves are operating normally, whether the motor is faulty
Second, check whether the vacuum pipe is closed and whether the seal is leaking
Third, check whether the vacuum valve is open, whether the vacuum pump is refueled or whether the vacuum pump water tank is filled with water, the vacuum pump is in the right direction of rotation
Fourth, check whether the mixing slurry is eccentric and the scraper is badly worn
Fifth, check the scraper plate for foreign objects stuck, resulting in the inability to turn flexibly
Sixth, check whether the homogenehead is normal, whether there is a foreign object stuck in the homogenehead head, whether the electronic cabinet relay jumps out, the limit switch is released.
