Problems solved by technology

Gear pumps or rotor pumps are used, which have simple structure, small size, relatively easy manufacture, and low cost, but the phenomenon of displacement pulsation has always plagued the filling industry. Due to the existence of displacement pulsation, through gear pumps or rotors The pump cannot discharge the material quantitatively, which makes the weight of the product after filling inconsistent, and makes the speed of the actuator unstable, causing vibration and noise, thereby limiting its scope of use; and the use of vane pumps can effectively solve the problem of material filling. The pulsation phenomenon that exists during installation, but its structure is complex and the cost is high
The existing vacuum filling technology is used when the rotor pump is used to realize quantitative filling. However, when the technology is used, it is easy to cause the material to block the vacuum port when the pump is stopped. The material flows into the vacuum port, which is inconvenient to clean and affects work efficiency

Embodiment Construction

[0027] Depend on Figure 1-Figure 4 It can be seen that the low-pulsation rotor pump of the present invention includes a pump body 11 and a pump cover 10 pressed over the top of the pump body 11. The pump cover 10 is provided with a feed port 26 connected to the feeder. There is a pump chamber 12, the left rotor 8 and the right rotor 9 corresponding to and engaged with the left rotor 8 are respectively placed on the driving shaft 13 and the driven shaft 14 in the pump chamber 12, and the driving shaft 13 and the driven shaft 14 are in the opposite direction Rotate, so as to drive the left rotor 8 to engage with the right rotor 9 and rotate in reverse. In the pump chamber 12 above the joint of the two rotors, there is a loading area 15 opposite to the feed port 26. Below the joint, there is an outlet. The feed port 16, in this embodiment, each of the rotors 8 and 9 has eight teeth, each tooth is arc-shaped, and each rotor is twisted from its upper end surface to its lower end s...

Abstract

The invention relates to a method for realizing fixed-amount conveying of material and a special low-impulse rotor pump. The method is that: material is continuously supplied to a material carrying section (15) through a material inlet (26); then a servo motor drives a left rotor (8) and a right motor (9) to rotate; the material enters the material carrying section between two adjacent gears of the rotors (8, 9); the rotors (8) and (9) are meshed with each other in a rotating way, the material is pushed to a material outlet (16) to be discharged. The special low-impulse rotor pump comprises a pump body (11) and a pump cover (10) pressed above the pump body (11); the rotors (8) and (9) are corresponding to each other; gears on the surface is spiral rotor pair . By adopting the technical proposal, the rotor pump can effectively reduce discharge impulse with low cost and simple structure.

Description

technical field [0001] The invention relates to a method for quantitatively conveying materials used in food, chemical and other industries for filling viscous, thick, or pasty materials containing small pieces of soft substances. At the same time, it provides a special low-pulsation Rotor pump. Background technique [0002] At present, when using similar equipment on the market to quantitatively fill food and chemical viscous, minced or pasty materials containing small pieces of soft substances into products, gear pumps, rotor pumps and vane pumps are mostly used. Gear pumps or rotor pumps are used, which have simple structure, small volume, relatively easy manufacture, and low cost, but the phenomenon of displacement pulsation has always plagued the filling industry. Due to the existence of displacement pulsation, through gear pumps or rotors The pump cannot discharge the material quantitatively, so that the weight of the product after filling is not uniform, and the spee...
