West tell you: water treatment filter using the matters needing attention
Filtration equipment use should be paid attention to:
Cardiac stainless steel strainer before use must complete check parts and sealing ring, is damaged, then put it well as required.
Derive new filter must wash clean with detergent (please dont use acid cleaning) with high-temperature steam sterilization, disinfection, wash after wash the filter in place, to avoid pollution.
Cardiac filter installation time dont pick up the import and export, pipeline filter plate on the edge of the mouth is a liquid inlet, pipe joint in filter socket outlet pipe is clean liquid.
Derive the new filter manufacturer in clean production encapsulated with plastic bag inside the room is not used do not tear the plastic packaging, use to demand higher filter, installed after go through high temperature steam sterilization.
Filled filter inserted into the mouth, the filter must be vertical, inserted into the mouth after plate buckle edge fin, twist screws can be fixed.226 the filter after the entrance of the interface, clamping should rotate 90 degrees, this is the key installation, if there is a bit not careful, will not seal, easy to leak, will not use requirement.
Cardiac filtering liquid into, should open the vent above the filter switch, let the fluid filled cylinder, otherwise the filtering effect is not good.
Filled cylinder pressure gauge is liquid pressure display table, if it is a secondary filter, the filter pressure gauge index slightly less is normal phenomenon, the longer you use, the pressure increases, the velocity decreases, this shows that most of filter gap have been blocked, flush or replace filter.
In filtering, use pressure generally at about 0.1 MPa, can satisfy the production needs, with time and flow rate increases, the filter pore jams, pressure increases, generally not more than 0.4 MPa, the highest must not exceed 0.6 MPa.Otherwise it will damage the filter element or the breakdown.
Left back flush filter, must use sterile water, otherwise it will pollution filter.Recoil, the original export import, using sterile water in the opposite direction (pay attention to the close concentrate filtration pipe), open the drainage outlet, operators see filtrate improved markedly.
Derive complete production need not when, as far as possible the filtrate, light down time is not long, generally do not open the machine, filter, dont pull down time should not be long or filtrate overnight deposit, downtime must clean the filter and filter can also use the recoil (method)
.
Is left free, pay attention to the need of flow, pressure, pump lift to match, the selection of vortex pump is generally selected, infusion pumps, centrifugal pumps do not apply. |
