Embodiment 1
[0014] The invention provides a filling vane pump for an emulsion explosive charging machine, such as figure 1 , figure 2 As shown, a pump body 1 is included. The pump body 1 has a pump body 8, a pump bottom 9 and a pump cover 10. The pump body 1 is provided with a rotor 2, and the rotor 2 is provided with a guide groove. 2 is provided with an inner stator cam 3, the rotor 2 is provided with an outer stator cam 4, the cams 3, 4 are provided with protrusions and recesses, so that when the rotor 2 rotates, the blades 5 guide While the groove moves circularly with the rotor 2, it extends and retracts into the outer circumference of the rotor in the radial direction. The blades 5 are made of non-metallic materials with higher strength, or the outer surface of the non-metallic materials is coated with a high bending strength material. The structure composition.
[0015] The rotor 2 is connected to the reducer 7 and the drive motor 6 to provide power for it.
[0016] In order to incre...

The invention provides a filling vane pump used on an emulsion explosive filling machine. The filling vane pump comprises a pump body, wherein a rotor is arranged in the pump body; an inner stator cam is arranged in the rotor; an outer stator cam is arranged outside the rotor; convexes and concaves are formed on the inner stator cam and the outer stator cam, so that when the rotor rotates, vanes can stretch out of / retract into the circumference of the rotor in the radial direction while doing circular motion in a guide groove along with the rotor. The filling vane pump provided by the invention adopts a special structural style for emulsion explosive filling, and reduces force of friction produced by emulsion explosive filling. Moreover, the vanes, a pump bottom, a pump cover, an inner stator and an outer stator are made of nonmetallic materials with relatively-high strength, or are made of materials with high bending strength and coated by nonmetallic materials. Thus, metallic friction between the vanes and rotor / the pump bottom / the pump cover / the inner stator cam / the outer stator cam is avoided. As the nonmetallic materials can efficiently absorb impact force and produce less heat caused by friction, the safety of the emulsion explosive filling machine is improved.
Description
Technical field [0001] The invention relates to a filling vane pump for an emulsion explosive charging machine. Background technique [0002] The filling vane pump used in a kind of emulsion explosive charging machine developed by our company realizes the filling purpose through the expansion and contraction of the vane on the rotor during the filling process, so that the vane and rotor, pump bottom, pump cover, Metal friction is likely to occur between the sub and outer stator, which increases the risk of charging. Summary of the invention [0003] In order to solve the above-mentioned shortcomings and deficiencies, embodiments of the present invention provide a filling vane pump for emulsion explosive charging machine that reduces the friction between the blade and the rotor, the pump bottom, the pump cover, the inner stator, and the outer stator. The technical solution is as follows: [0004] The present invention provides a filling vane pump for an emulsion explosive charging ...
