Product Features

This machine is suitable for wet shearing, crushing, grinding and refining of explosive materials. The shear crushing pump adopts belt drive mode and the machine cover is designed as quick opening mode. All connecting bolts adopt external falling bolt full sealing nuts to facilitate cleaning of the machine cavity and rotating stator. The rotating stator is designed to be replaceable for maintenance and replacement. The main structure ensures that there is no hidden danger of gunpowder residue machining screw holes on the machine cavity. The motor is Wuxi Xian Da variable frequency explosion-proof motor, a designated enterprise of Sinopec. The bearing seat is cast by HT250 ductile iron. After several years of aging treatment, quality factors such as equipment unchanged and no oil leakage are ensured during high-speed transportation. Three Japanese NSK high-speed fully enclosed high-quality bearings are installed in the bearing seat to ensure the accuracy of the main shaft and rotor during high-speed operation. The working cavity and rotating stator of the shear crushing pump are made of high-quality stainless steel SUS316L and then rough machined after high-temperature forging. The internal diameter and phase structure of the forged parts is closer, more wear-resistant and corrosion-resistant. The final finishing of spare parts is completed by precision machining and manufacturing by the machining center.

Sealing of shear crushing pump: we adopt vacuum water circulation sealing vacuum device, and the water continuously pressurizes the back end of the seal through the spiral groove under the high-speed rotation of the main shaft. As the sealing chamber is equipped with water circulation labyrinth device, the water decompresses from the reverse spiral labyrinth and continuously circulates backward, and a trace of water flows out from the shell seal, ensuring that the cavity materials cannot contact the sealing friction surface, secondly, the vacuum device designed on the outside of the rotor generates a certain vacuum in the sealing area during high-speed rotation, which more effectively isolates the contact between the material and the shaft seal, so that the material in the high-speed crushing will not flow into the sealing vacuum area, and the material contact seal Extrusion and friction and other hidden dangers further improve the reliability.

The shear crushing pump adopts a vortex shear crushing form, which is mixed with flammable and explosive materials by water or other explosion-proof fluids to effectively ensure the safety of crushing flammable and explosive materials in water or other fluids. The entire crushing process of the equipment is a closed-loop shear crushing method, and the rotating speed and cycle crushing times are adjusted in the production process to achieve the required mesh number. The normal distribution of mesh size of the material after shear crushing is narrow and the degree of sphericity is high.

Product Principle

The working principle of the shear crushing pump is that under the high-speed drive of the motor, the material mixture enters the shear crushing working chamber through the feed port, and is subjected to high-speed shear, high-frequency oscillation, impact extrusion, etc. and hundreds of thousands of strong hydraulic shear and turbulence per minute in the narrow channel between the multi-layer rotor and the stator, and the droplets in the working chamber are continuously sheared, ground, dispersed and emulsified. In the structure, a special device is designed to produce a cavitation effect in the tooth groove on the side of the rotor under high-speed rotation. In the strong cavitation micro-explosion, the liquid particles of the material are subjected to high-speed shearing, peeling and grinding again to form flakes. At the same time, the external teeth of the rotor and the slope of the shell are subjected to squeezing and friction again, rolling and kneading, finally, the sheet is kneaded into a spherical or hemispherical state and flows out from the outlet. According to the mechanical effect, the higher the rotor speed, the faster the cycle, the greater the friction, the better the ball.

Note: The user provides relevant parameters of material characteristics, or brings materials to the production base for on-site testing, and the manufacturer selects the internal structure of the grinding disc according to the characteristics of the medium.
