9, drivers and other personnel often check, once the abnormal sound or vibration, heat and other phenomena, should immediately stop processing, troubleshooting can start after this.
Three, working principle
When the impeller rotates, the centrifugal force causes the air to move forward and forward to form a series of spiral motion. The impeller blades of air between the spiral spin up and the gas outside the pump body into (suction by the suction side) tank, when it enters the side channel, the gas is compressed, and then return to the impeller blade again accelerated rotation. When the air along a spiral path through the impeller and the side slot, each blade increases the degree of compression and acceleration, with rotation of the gas kinetic energy increase, so that the gas pressure through the channel along the side of a further increase. When the air reaches the connecting point of the side slot and the discharge flange (the side channel narrows at the outlet), the gas is extruded and the pump body is discharged through the outlet silencer 4.
