Product Description Product DescriptionPSB series centrifuge is a top discharge, big hinged cover centrifuge with simple structure and reliable performance.The filtration time can be adjusted according to demands. The solid cake can be washed completely and can make no damage to the particle shape. It is easy to wash the filter cloth , the operation and maintenance are more convenient.Once the materials to be separated enter the fast-spinning basket, it will be filtrated by the filter liner under the centrifugal force. The liquid flows out through the liquid outlet, but solids deposit on the internal wall of the basket. Once the solid cake reaches the rate capacity, feeding stops. Wash the solids cake, and then drain out the washing water. Finally stop the machine. The solid cake is discharged manually and move to next batch.Technical ParametersMain features:Liquid damping vibration islator,No foundation for installation , the operation and maintenance are more convenient.Arch cover design with suifficient strength and rigidity can effectively prevent the influence of cover deformation on sealing performance.Humanization design:No foundation for installation ,broad working platform,various waring and notice signs,etc.Safety protection device:over vibration protection,over current protection,overload protection,etc.ensure the safety of the machine.Centrifuge structure describe Centrifuge is mainly composed of main machine(include base,basket,cover,mainshaft assembly,motor assembly,etc.),electric control system and other parts.Base and shock absorption system Platform base structure,rigid connection between casing and base,bearing structure of the basing.The platform base is made of carbon steel,inner suface lining with ss304,platform base lining with SS304Shock absorption system adopts liquid damping support system with spring,good vibration resistance,its vibration isolation effect is more than 95%.Platform base structure lower the center of gravity ,and stabilize the machine.2.1.5.No-foundation installation form,easy to install and move,platform base can be used as working platform,which is more conveient to operate.Basket:The centrifuge basket is welded,having strict dynamic balance test after tempering treatment,with high balance accuracy,100%non-destructive detection,the weld is too smooth without cleaning dead corner.The basket has no reinforcing hoop,which reduces cleaning dead corner and is easy to cleanCover :Adopting big hinged cover,which is more conveinent to maintenat and cleanAdopting balance device (sping insinde)to open the cover,No other power device is needed.Flange and seal ring combination structure are used at the fitting part with the casing,and the seal ring is equipped for sealing;+Fully machined large flange to ensure reliable sealing between flange and basing;Equipped with explosion-proof lamp and sight glass,it is convenient to observe the working condition of inner chamber of the centrifuge.Main shaft assembly:Independent bearing seat design,relaiable performance,and convenient disassembly and maintenance;The bearing seat and bearing cover are made of steel castings with good strength;Large bearing support span ,larger carrying capacity;Double O-ring sealing structure is adopted at the top of the main shaft and the basket,with good sealing effect;The joint between the main shaft and the bottom of the basket is sealed with a combinantion of a static o-ring and a framework oil seal,it can avoid the direct corrosion of the main shaft caused by the mist liquid and gas,and greatly improve the anti-corrosion ability of the main shaft;Equipping with lubricating oil adding device,easy to maintain.Motor assembly:Equipped with explosion-proof and energy-saving motor,onsite explosion-proof button and antistatic belt;Equipped with belt guard and motor guard to ensure safe operation.Electrical control:The main motor is started by inverter ,smooth starting;Dydamic braking;It is equipped with onsite explosion-proof button and connected with electric control box to realize remote control;The main motor is vertial exposion-proof energy-saving motor;Phase/frequency/voltage:3phase/50HZ/380v;Motor explosion-proof grade :EXDBT4;Motor protection grade:IP55;Cable channel:bottom in ,bottom out;Transmisson type:antistatic V-belt;Safety protectionOvervibration protection:acceleration sensor is installed on the machine,a detector is installed in the electrical control cabinet to display the vibration level of the machine.set the first level alarm when leaving the factory and reduce it to the safe speed.the second level alarm,the machine stops running.Emergency stop botton:when this button is pressed,the converter stops and the machine stops by braking. Nitrogen protection system Nitrogen protection system is an option for customers when the machine working in flammable or explosive places,which can improve the safety of centrifuge used in these occasions,so as to reduce the use risk. Fill a certain pressure of nitrogen into the closed centrifuge chamber to replace the air in the chamber, and reduce the oxygen content of the centrifuge to the safe range, and then keep the micro positive pressure in the centrifuge chamber all the time to ensure that the oxygen content in the centrifuge is within the safe range, so as to improve the safety of the centrifuge. Before nitrogen filling, confirm whether the pressure, flow and nitrogen concentration of nitrogen source meet the use requirementsNameParameterInfluenceNitrogen filling pipe diameterD16The smaller the nitrogen filling pipe diameter is, the longer the replacement time will beNitrogen source pressure2-3barSlightly affect nitrogen filling replacement timeNitrogen charging pressure (working condition)1.5barAffect nitrogen filling replacement timeNitrogen flow (standard condition)0.8-0.9m3/min(Large flow )+0.05m3/min(small flow)Affect nitrogen filling replacement timeNitrogen consumption of large flow nitrogen filling(standard condition2.5-3m3 in 3 minutesAffect nitrogen filling replacement timeNitrogen purity≥99%The lower the purity of nitrogen, the more times the replacement time of nitrogen filling and the oxygen content of centrifuge meet the requirements (conventional 4% ~ 6%Under the above conditions, it is found that the replacement time of nitrogen filling is about 5 minutes when the oxygen content in the centrifuge reaches 5%.
