The invention relates to the technical field of vacuum pump noise reduction, and discloses a screw vacuum pump noise reduction device, which includes a motor and a pump body, and the output shaft of the motor is fixedly connected to the pump body. The shock-absorbing and noise-reducing device includes a shock-absorbing sleeve and a conductive sleeve. The shock-absorbing sleeve is sleeved on the output shaft of the motor, and the conductive sleeve is sleeved on the shock-absorbing sleeve. The shock-absorbing sleeve is located in the middle of the motor output shaft. ,The conductive rod and the conductive sleeve are flexibly connected. The noise reduction device of the screw vacuum pump is equipped with a shock and noise reduction device for use. The vibration is absorbed and reduced, and the noise generated by the vibration will be transmitted through the shock-absorbing sleeve, the block and the conductive sleeve due to the faster sound transmission of the object, thereby reducing the divergence of the noise and increasing the practicability of the device.
Description
technical field [0001] The invention relates to the technical field of vacuum pump noise reduction, in particular to a screw type vacuum pump noise reduction device. Background technique [0002] A vacuum pump refers to a device or device that uses mechanical, physical, chemical or physicochemical methods to pump air into a pumped container to obtain a vacuum. Generally speaking, a vacuum pump uses various methods to improve, generate and maintain a vacuum in a closed space. Vacuum device, according to the working principle of the vacuum pump, the vacuum pump can basically be divided into two types, namely the gas capture pump and the gas transmission pump, which are widely used in metallurgy, chemical industry, food, electronic coating and other industries. The existing dry type When the screw vacuum pump is in use, it is widely used because of its low noise, but the part connected to the pump body and the motor will still vibrate due to the rotation of the motor, resulting...
