The high-shear emulsifying pump is a precision combination of a rotor and a stator that generates powerful shear force during high-speed rotation, achieving mixing, homogenization, dispersion, and crushing. The purpose of emulsification is to efficiently disperse materials online. Installed on pipelines, it can continuously process materials, eliminating quality differences between batches. The basic structure of a high-shear emulsifying pump consists of a pump chamber and a pair of stator and rotor.
Operating Principle of High-Shear Emulsifying Pump:
Electric energy serves as the power source for the emulsifying pump. It primarily relies on electrical support to convert electric energy into the power for high-speed rotation of the rotor. Under the action of the powerful shear force generated by the high-speed rotation of the rotor, the products to be mixed are crushed and emulsified before being discharged from the bottom of the emulsifying pump.
Structure of High-Shear Emulsifying Pump:
The body of a high-shear emulsifying pump mainly consists of the outer and inner sides of the pump chamber. The outer part of the pump chamber is made of stainless steel model SS316, which is wear-resistant and not prone to rust. The internal structure of the pump chamber is also made of stainless steel, which is more corrosion-resistant and wear-resistant than the external part, allowing for better subdivision of some oxidizing liquids without damaging the pump body.
A high-shear emulsifying pump is a machine capable of fully refining and homogenizing materials. Its name should derive from its ability to mix oily substances (oil phase) and aqueous substances (water phase) to form a uniform emulsion. It has refining, dispersing, and homogenizing functions and is mainly used for liquid-liquid emulsification and homogenization, as well as fine dispersion of solids (powder particles).
During the operation of a high-shear emulsifying pump, if a malfunction occurs due to improper operation or aging and wear, what are the solutions?
1.If the pressure cannot be found or adjusted after starting the high-shear emulsifying pump, the following factors should be considered: firstly, the middle and lower orifices of the pilot may be cold-plugged; secondly, unloading may be the main task or the pilot may be jammed and damaged; due to thrust cold seal ring donation and other hazards. The solution is to repair, restore, and replace items according to the problem.
2.If there is a collision sound during operation, it may be due to increased clearance in the bushing, debris in the pump body, or clearance between the plunger bearing seat and the plunger bearing housing. The solutions are to replace the bushing, clean up the debris, adjust the motor and pump to be coaxial, and tighten the compression screw sleeve.
3.If the high-shear emulsifying pump exhibits significant pressure pulsation, insufficient or no flow, vibration, and severe noise in the target pipeline, the following factors should be considered: air in the pump suction chamber has not been cleaned out; plunger seals are suctioning air; the suction pipe is too narrow or bent, the suction and discharge valve springs are broken or the cutting core is damaged, the suction valve plug is not tight, and the suction filter of the liquid tank is clogged. The solutions are to loosen the air screw of the pump body to vent the air, remove the drain valve and inject liquid into the plunger chamber, replace the suction hose or eliminate dead ends, replace the filter element or core, tighten the suction valve plug, and clean the suction filter of the liquid tank.
4.High temperature in a high-shear emulsifying pump may be caused by damaged shafts, insufficient or unqualified lubricating oil. The solutions are to add oil or clean the oil tank and change the oil, repair the crankshaft, and replace the bearing bush.
