The relationship between the current and pressure of the Roots blower

Mingfeng Luoci Blower Manufacturer shares with everyone the relationship between the current and pressure of blower equipment.
Mingfeng Roots blower manufacturer shares the relationship between the current and pressure of the blower equipment. The impact of pressure is actually very important because the operation of the blower is a multi-faceted interaction, driving each other.
The pressure of the Roots blower is related to the current. Under the same speed and voltage conditions, the greater the power, the greater the pressure. Power = voltage x current, heat, which means that under the same speed and voltage conditions, the greater the current, the greater the power.
When the motor speed is fixed, the pressure suppression will result in a large motor load, which can easily cause overcurrent and burn out the motor. The Roots blower is a positive displacement blower, and the air volume delivered is proportional to the speed. When the impeller rotates, the two impellers inhale and discharge air three times. Compared with the twin-blade blower, the gas pulsation is small, the load variation is small, the mechanical strength is high, the noise is low, and the vibration is small. The two impellers are mounted on two parallel shafts, and a small gap is always maintained between the impeller and the inner surface of the oval casing. Because the impeller rotates in reverse at a constant speed, the amount of gas inevitably captured by the casing and the impeller is transported from the intake side to the discharge side.
The pressure and current of the Roots blower are closely related, so during use, we should pay attention to ensuring the stability of the current and voltage to ensure the normal operation of the blower.
