As mentioned above, rotary drum (P) is with two rotary drums, one is with the blade rotary drum 32 of two blades 30 on the section 180 degree directions, another is the groove rotary drum 36 of with groove 34 on the section 180 degree directions, blade and the tight interlock of groove during rotation on two rotary drums, cut off the series fluid flow between suction inlet 22 and the outlet 24, along with two

rotary drums

32,36 rotation, follow blade 30 from exporting 24 extrusion, because groove 34 and blade 30 tight interlocks play the partition effect between suction inlet 22 and the outlet 24 from the fluid of suction inlet 22 inspirations, same two

rotary drums

32,36 also close fit, fluid can not adverse current, so along with the rotation of pump, can pumping fluid.

Because need seal when pump gas or low-viscosity (mobile) liquid, so the cylindrical shell inner face and the top and bottom of rotor cover 28 make of synthetic rubber, in addition, metal slide block 38 on the blade is fixed on the spring 42 in the blade box 40, rely on the elastic force of spring 42, blade is closely contacted with the groove wall, thereby guarantee the seal in the working procedure.

But there is a series of problem in this rotary drum pump of Shi Yonging in the past;

At first because the degree of eccentricity of two rotary drums itself produces noise inevitably during fast rotational; Secondly after long-term the use, accumulate foul on the contrary valve of specialty, check efficient is reduced, simultaneous faults increases, and the repair time increases;

At last, particularly, be in during interlock on the straight line, increase friction and impact noise inevitably because this rotary drum pump has even numbers blade and groove.

Summary of the invention

The purpose of this invention is to provide a kind of energy and eliminate the existing deficiency of rotary drum pump in the past, on the groove rotary drum section several angle odd number groove is set for this reason, on the corresponding blade rotary drum odd number of blades is set also, the tight interlock of groove and blade during rotation, but they are not in a straight line, thereby significantly reduce the rotary drum pump rotor member of the band odd-numbered blade of noise.

The present invention is achieved in that and it is characterized in that deciding pivot by motor in the pump case, the drive portion that rotor and shaft gear are formed;

Reduction gear with the kneading of drive portion shaft gear;

By the driving gear on the driving shaft of reduction gear place with therewith with the linkage part formed of follower on the driven shaft on the driven shaft of engagement in 1: 1;

By be located at suction inlet on the driven shaft one side rotor cover and outlet and pump cover and be located at the blade rotary drum of two rotary drum blades of section 180 degree direction bands on the driving shaft and corresponding driven shaft on the rotary drum pump part formed of the groove rotary drum of two rotary drum grooves of section 180 degree direction bands;

Proposition has the rotary drum pump rotary drum member of odd number of blades, on the groove rotary drum section several angle odd number groove is set, odd number also is set by blade boss and resilient member and the blade part that formed by the impeller of its elastic force effect on the corresponding blade rotary drum, the tight interlock of groove and blade during rotation, but they are not in a straight line, thereby significantly reduce noise.

The present invention can root a tree name design capacity adjusts the odd number number of blade part and groove, produce the product of different size, because rotary drum blade part and groove are odd numbers, therefore also can Keep silence during a large amount of fluid of pumping, because the blade part and the groove of rotary drum are odd numbers, can balanced rotation, compare with the rotary drum pump of two blades and groove, significantly reducing the noise in the operation process, is very favourable all to home-use and commercial using therefore.
