Roots blower technology principle: screw blower working principle and characteristics


 Roots blower technology principle: screw fan working principle and characteristics The development of screw fan is late, is a new type of rotary fan, divided into single screw and double screw, the common market is double screw. The twin-screw structure was invented by the Swedish Riesman and was used in the field of compressors. Until the end of the 20th century, the twin-screw structure developed rapidly in the field of blowers, showing good convenience in many applications, such as energy saving. Smooth, etc. It has good performance and gradually replaces traditional fans such as Roots in many fields. The structure of screw fan Take the twin screw blower as an example, the screw fan is generally based on the outer cover. Main engine. Motor. Air filter. Muffler. Oil pump, oil tank and oil filter. Twin-screw blowers can be customized according to customer standards, such as enclosures. Change to oil-free system, etc. As a key component of the screw fan, the structure of the screw host directly determines the performance of the fan. The screw host is mainly composed of the shell host. Screw rotor. Gear box. Bearing. Shaft seal and other main components. Two. The working principle of screw fan The operation principle of the screw fan is two parallel Yin and Yang rotor "∞" shape synchronous gear, the rotor reverse high-speed rotation through the synchronous gear, the rotor reverse high-speed rotation. With the periodic change of the rotating working volume of the rotor, the working period of the gas fan can be divided into inspiratory. Compression and exhaust three processes. The process is as follows: 1. Inhalation process Capacity of gas entering between rotor teeth through suction inlet. As the rotor rotates, the capacity between the teeth expands. When the capacity between teeth reaches a value, the capacity fusion process between teeth ends. 3. Exhaust process When the capacity between the teeth is connected to the exhaust port, the exhaust process begins. During the rotation of the rotor, the capacity between the teeth is continuously reduced, and the compressed gas is sent to the exhaust pipe.
