Maintenance of fermenter agitator magnetic steel bearing filter clip joint hose solenoid valve ball valve
Maintenance of fermenter agitator magnetic steel bearing filter clip joint hose solenoid valve ball valve
Maintenance of agitator: check and tighten the stop screws installed in each part of the agitator shaft after each opening of the tank cover. 2. Adjustment of the position of the upper magnet steel: the normal distance between the upper magnet steel and the bottom of the tank is 1-1.5 mm. If the distance is too small, the bottom of the upper magnet steel will touch the tank, at this time will cause the stirring shaft can not rotate or the stirring shaft has jumpy and accompanied by a larger noise phenomenon; It is possible for the agitator to shut down when the fermentation broth is thick and noisy. 3, bearing replacement: after one to two years of use, the bearing noise obviously larger or stir shaft obviously swing to replace the bearing. Remove bearing bottom cover, remove shaft head screw and bearing gland, remove shaftRemove the end cap at the bottom of the bearing block, remove the end cap at the bottom of the bearing block, remove the clamp spring at the bottom of the bearing block, take out the stirring shaft from the top down, take out the bearing and replace it, and install it again. Four, filter replacement: because the air contains a lot of dust, after a certain period of time, the filter on the micro-hole will gradually plug, on the one hand, causing serious shortage of air flow and air pressure drop larger, at the same time may cause infection, at this time the need to replace. When Idle, the filter element should be removed from the air filter, and drain the condensate in the filter. Five, card socket joint leakage: tighten the pressure cap on the street can be. Air Hose: to prevent the connection of the two ends of the air flowmeter hoseIt is recommended to replace the hose every two years. Seven, solenoid valve maintenance: solenoid valve is used for the cooling of fermenter, the spool of solenoid valve stuck, spool seal failure and damage of solenoid coil can cause the failure of solenoid valve. Fault judgment: to ensure the circulation pump operation and circulation pipeline under normal circumstances, the temperature only does not rise zui big reason is solenoid valve leakage or valve core stuck, the other reason may be electric heater burned out. According to the water injection switch, the water injection switch indicator light is on and the top surface of the solenoid valve is non-magnetic, no cooling water is discharged, the coil is broken. Close the solenoid valve, drain cooling water leakage, spool seal failure or debris stuck spool. Eight, after the completion of fermentation and sterilization should be timely cleaning, installation process should ensure that the air distributor reset, timely replacement fill hole gasket, such as water leakage should also replace the bottom valve gasket. Maintenance of ball valves: since the seals inside the ball valves are made of two hemispherical tetrafluoroethene, there may be leakage between the seals and the spool after prolonged use, loosen the socket nuts at both ends of the valve, then tighten the cylindrical joints at both ends of the valve (normally there should be some resistance to turning the handle)
