Engineering Cases
Rotor Pump for Defoamer
The defoamer used in defoamer production serves to reduce and hinder the formation of foam in industrial systems. During industrial processes, foam can cause significant harm, such as decreased production capacity and raw material waste. With advantages such as increased productivity, optimized work efficiency, precise product quality control, reduced environmental pollution, and cost control, it is widely used in various industries. Its functions include enhancing the wetting between polyurethane slurry and fibers and reducing bubbles. The viscosity of the defoamer varies widely during production, being high-temperature and high-viscosity near the finished product stage. This poses particularly high requirements for the conveying pump. Helsh-Tech rotor pumps can be customized according to different process requirements and characteristics to adapt to changes in viscosity and temperature under various operating conditions. They are equipped with suitable built-in safety valves to protect the pump and online equipment, effectively ensuring safe production.
Homogenizing Dye Emulsifying Pump
Over the years, dyes are classified by state into color pastes, oily color pastes, aqueous color concentrates, and oily color concentrates. By application, they are divided into ceramic pigments, coatings, textiles, plastic dyes, and artificial dyes. The emulsified dyes and pigments are required to be uniform, with strong coloring, ensuring color, fastness, light resistance, and abrasion resistance. The specificity of dyes has evolved fiber coloring from a physical process to a chemical process. After activation, they are widely used in textiles, paints, plastics, paper, leather, food, and many other fields. Helsh-Tech homogenizing emulsifying pumps perform pre-dispersion and mixing pretreatment on dye slurries, effectively improving refinement effects, significantly enhancing product quality, and substantially increasing production efficiency.
Multi-Tube Mixing and Homogenizing Emulsifying Pump
Our multi-tube mixing and homogenizing emulsifying pump can achieve online mixing and homogenization of materials with different compositions according to proportional requirements. This product is widely used in production processes involving mixing, homogenization, emulsification, and neutralization reactions of multiple materials. Through reactor stirring and intermittent operations, it provides homogenized, mixed, and emulsified media to the core equipment for continuous online production, simplifying the process, saving labor costs, reducing workload for operators, and improving production efficiency and product quality.
Rotor Pump for Adhesives
As we understand, polyurethane adhesives in adhesive production use heat transfer oil for several hours of circulation heating and cooling. After solids are manually added to the reactor, the conveying pump transports materials into the mixing pot for slow heating to initiate ester reactions. Before esterification, the monomer viscosity is not high, but during neutralization, the viscosity changes with the boiling point and flash point characteristics of the chemical materials, causing temperature variations. Therefore, when selecting conveying equipment, it is required to have a wide applicable viscosity range. During special processes where degassing and dehydration occur, there is negative pressure. At this time, when the pump is operating, the self-priming must be strictly stable. Based on practical application experience and manufacturing technology, Helsh-Tech rotor pumps are specially customized for pump clearance, smoothness, sealing, etc., according to material characteristics, ensuring stable and safe material conveying with high efficiency.
