3T Belt Pulley Pump, including the pump body, which houses a rotor with four blade slots. The slots are evenly distributed around the rotor, with two adjacent slots parallel and the other two perpendicular. Each slot contains a blade. The pump body features an intake, exhaust, and drive shaft, with oil grooves in the shaft and bushings between the shaft and body, which have holes corresponding to the shaft's cross holes. The intake is equipped with a one-way valve, and a belt pulley is fixed to the drive shaft, connecting to the engine via a belt. This innovative vacuum pump rotor design has four blade slots around its perimeter, allowing for longer slots to maximize the swept volume and improve efficiency. Additionally, the improved channel design addresses oil leakage issues, and the oil seal between the drive shaft and belt pulley can be eliminated, thereby reducing costs.

Common issues with 3T belt pulley pumps include insufficient vacuum level; excessive temperature in the pump's bearing area; abnormal operation of the motor and vacuum pump; oil leakage and spraying from the vacuum pump; difficulty in starting the vacuum pump; and inability to suck up liquid. Below, I will provide detailed solutions for these six common problems, helping you to eliminate frequent issues with vacuum pumps and maximize their performance.
