Operation: After the Roots blower is running normally, the operator should pay close attention to the operating conditions of all parts, and observe the temperature of each part of the machine, the vibration of the machine, and the noise of the muffler at any time. If there is any abnormality, stop immediately.

Shutdown: For the normal stop of the Roots blower, first open the bypass pipe to exhaust. After the wind pressure drops (basically zero), cut off the power supply, close the intake valve and the cooling water system. In case of abnormal shutdown, the bypass pipe shall be opened first for air release.

Maintenance: During normal operation, check the temperature of bearings, lubricating oil in the tank, motor, etc. every 1~2 hours, and shall not exceed the specified value. Roots blower is noisy during operation. In order to reduce noise, in addition to installing a muffler, some simple methods can be used to reduce noise, such as the crypt method. Dig a 4~5m3 underground crypt, cover the crypt, use a duct to introduce the suction port into the crypt, and use another duct to introduce external air into the crypt. Two ducts as far as possible to step on the bottom of the crypt, can reduce a lot of noise.

operating elements of roots blower:

Check all parts of the blower, whether the parts are complete, the looseness of the bolts and nuts, the installation quality of the fasteners and positioning pins, and the installation quality of the exhaust pipe and valve.

In order to ensure the normal operation of the fan, it is not allowed to carry external loads such as pipes, valves, frames, etc. Check the correct quality of the blower and motor.

Check whether the surrounding of the unit base is firm and whether the anchor bolts are firm.

The structure is an ordinary three-leaf Roots blower, which is mainly composed of two parts: the driver and the head. The driver is the power source of the blower. It is both a motor and a diesel engine. The head is the main working part of the Roots blower. The purpose of gas transportation is achieved through regular operation. To understand the working principle of Roots blower, fully understand the head structure of Roots blower. The main components of the head are wall panels, shells, active impellers, automatic impellers, active automatic gears, main and auxiliary fuel tanks, bearings, etc.

The working principle of Roots blower.

Simply put, the gas is forced from one end to the other through a pair of impellers to achieve the purpose of air transportation. This principle was proposed by the Roots brothers in the United States, so it is called the Roots principle. The blower made by Roots principle is called Roots blower.

the advantages of roots blower:

(1) When the middle distance is the same and the radius of the outer circle is the same, the exhaust volume of the three-leaf Roots blower with curved blades is greater than that of the double-leaf Roots blower. The displacement of an involute Roots blower is independent of the number of rotor heads.

(2) The vibration and noise of the three-leaf Roots blower are less than that of the two-leaf Roots blower. The life of the three-leaf Roots blower rotor bearing is about 15 longer than that of the two-leaf Roots blower bearing. In addition, the three-leaf rotor can use twisted-leaf rotor to reduce noise and vibration, but due to structural limitations, the two-leaf rotor cannot use twisted-leaf structure.

(3) The mechanical performance of the three-blade rotor is better than that of the two-blade rotor, which can better ensure the gap between the impellers and the impeller and the casing.

(4) Three-blade rotor Roots blowers, especially twisted-blade Roots blowers, have good noise and dynamic balance performance, so they are increasingly used in automobile supercharging.
