How to know when a system is working with cavitation it ? One way is mounted on the pump inlet side of a vacuum gauge and confirm that the pressure is equal to or higher than the nominal working pressure of the pump .
No cavitation vacuum table found the best way is to listen to the sound of the pump . Pump cavitation occurs emits a high-pitched sounds or screams . Sometimes it is difficult to bearing noise , coupling noise, or noise from nearby distinguish the machine , but can be distinguished empirically .
Through the failure of the entire system can also be found cavitation and air mixing , for example: More knowledge about Hydraulic tube fittings fittings Standard Health professionals caSince the pump suction dissatisfaction pump output flow will be reduced. This is enough to make the hydraulic cylinder or hydraulic operation of the motor slows down.Damaged by cavitation control valve , the valve active channel becomes large, the movement speed and time may be allowed .
System may show " spongy " action , particularly in the case of air into more so. Servo valve, mixed with air or the occurrence of cavitation in fluids will appear larger compressibility, the control circuit reduces the stiffness of the system operator can easily discover this phenomenon.How to find air into it ? Long observation tank level indicator level or number of bubbles on it. Ultimate aim is to put in the mail to separate air from the oil so that air is not sucked into the pump inlet . As mentioned earlier, to find the leakage point and take measures to eliminate it .Mailbox rational structure separated from the oil in the air is very important . Fluid in the tank a longer time of stay is obviously beneficial . Pump inlet and the system back to the oil farther away as possible , with the bulkhead between the two elongated away. It is necessary to set the screen ( Figure 2 ) .
