Roots blower

Abstract

A Roots blower, belonging to the technology field of blowers, comprises a motor, an impeller box, and a gear box. A muffler is connected with the air inlet port of the impeller box, an oil scale base is arranged on the wall body of the gear box, an oil scale hole of the oil scale base communicates with an oil chamber of the gear box, and an oil scale is arranged on the oil scale base and extended into the oil scale hole and contacts with the oil chamber. The inventive Roots blower has ideal noise reduction effect due to the arrangement of the muffler. The oil scale is extended into the oil scale hole arranged on the oil scale base and contacts with the oil chamber of the gear box, so that the oil scale can not be damaged and needs not to be repaired and replaced, and the oil scale can be conveniently taken out periodically or aperiodically to observe the oil conditions inside the oil chamber of the gear box.

Description

technical field [0001] The invention belongs to the technical field of blowers, and in particular relates to a Roots blower. Background technique [0002] Roots blowers are widely used. For example, the textile industry can be used to remove dust, the aquaculture industry can be used to add oxygen to fish ponds, and the sewage treatment industry can be used to aerate and increase oxygen, etc. The working principle and general structure of the Roots blower can be found in a large number of related documents such as Chinese patent documents, typical Chinese patent authorization announcements CN2238925Y, CN2830714Y and CN2830716Y. The Roots blower disclosed in the above-mentioned patent does not make technical instructions on how to reduce noise specifically. In addition, the structure of the oil dipstick of the gearbox of the Roots blower in the prior art including the above-mentioned patented technical solution does not meet the actual application requirements, and it adopts...

Problems solved by technology

The Roots blower disclosed in the above-mentioned patent does not provide technical guidance on how to reduce noise

In addition, the structure of the oil dipstick of the gearbox of the Roots blower in the prior art including the above-mentioned patented technical solution does not meet the actual application requirements, and it adopts a glass tube to reveal the oil condition in the gearbox, Because the glass is easily broken and difficult to replace, and it is easy to be attacked by dust and cannot be observed, it is difficult for the user to know whether the gearbox is short of oil. Once the gearbox is short of oil or even cut off, the entire gearbox will be damaged
