Features:
Platform base structure could lower the center of gravity and stabilize the machine. No foundation consruction makes convenient installation and repairing
Platform base with liquid damping isolators-Applying the liquid damping improves performance of vibration absorption in centrifuge
Inclined feed disk: we discarded the centeal feed or side feed method.
Air recoil and pneumaticauxiliary scraper: this technilogy effectively reduces the solids remained in the basket and effective resume the performance of the filter cloths
Nitrogen protection system: ensuing the safety during the operation.
Big hinged cover and CIP system, which avoiding cross contamination against the products.
Multipie safety protection devices: over-vibration protection, over-current protection, themal control Protection, cake layer controller. protection for scraper movement, protection when open the cover various signs and warming identifications
PLC control. touch screen, inverter control, dynamic braking. feedback barking, self-diagnosis of equipment fault, automatic control panel and DCS control interface.
Polished intemal exermal suifaces with roughness up to Rao 2-0, 4um, complying with the related requirements of CGMP
Anti-corrosion
The materials to be separated are normally corrosive. So for safety, the parts in contact with these corrosive materials must be anti-corrosive.
Material of constructions: 304, 321, 316L, 904L, TA, 2205, 2507etc.
When there is determined application experience or corrosion data, carry out coupon test and laboratory verification to ensure selected material meet anti-corrosion requirements.
Surface anti-corrosion treatment: PE lined, rubber lined and halar lined and F40, F46, PFA etc.
Anti-corrosion requirements of sealing elements can not be neglected; material of sealing elements shall ensure prevention against corrosion from acids, alkali and solvents.
The customer shall forward the physical and chemical properties of the material and washing liquid (chemical properties and separation temperature etc.) to the manufacturer so that it can make recommendations for centrifuge materials based on characteristics of the separation medium, and that the suitable seal ring, seal washer and filter cloth can be provided, thus ensuring anti-corrosion requirements on the centrifuge.
Explosion-proof
If the centrifuge works in the environment, where there are some explosive substances, the centrifuge should be explosion-proof. If the centrifuge becomes really explosion-proof, it should take a variety of measures in mechanical, electrical control and the accessories selection.
Electric control: explosion-proof isolator, non-touch dynamic braking system, static grounding and explosion-proof automatic control.
Mechanical system: explosion-proof motor, explosion-proof light, anti-collision and anti-static driving belt.
Explosion-proof accessories: nitrogen protection system, on-site explosion-proof control button.
Therefore, for those environments required explosion-proof, users can specify the filtration medium, requirement and degree of explosion-proof when they take orders, in order to buy the right equipment to meet the requirements of explosion-proof.
