High-Precision Metering
The components of the gear metering pump are precisely machined, ensuring the high precision of the pump. The metering accuracy can be as high as ±0.3% to ±1%. Under various conditions of temperature, viscosity and pressure, it can guarantee a stable and repeatable flow with good repeatability, thus meeting the requirements of various high-precision coating processes.
By precisely controlling the rotational speed of the gears, the output flow can be accurately adjusted, which further ensures that the coating amount of the coating liquid is precisely consistent, making the product quality more stable and reliable. For example, in the encapsulation of electronic components, it can ensure the uniformity of the thickness of the encapsulation layer and improve the performance of electronic components.
Stable Flow without Pulsation
Its working principle determines that it can achieve a pulsation-free output when transporting fluids. The discharged liquid is very smooth and uniform, avoiding problems such as uneven coating thickness and unstable coating quality caused by flow pulsation. It is especially suitable for coating processes with extremely high requirements for coating quality, such as the coating of optical films.
A stable flow output helps to improve the consistency and stability of coated products, reduce the scrap rate, and increase production efficiency and the product qualification rate.
Wide Viscosity Adaptability
The gear metering pump can transport fluids with various viscosities, ranging from thin liquids to semi-solids, and from Newtonian liquids to non-Newtonian liquids. It is especially suitable for transporting materials with high viscosity, such as bentonite slurries. There is no need to worry about problems such as reduced pump efficiency or inaccurate metering caused by the sticking or poor closing of check valves under high-viscosity materials. It has a wide range of applications in coating processes in industries such as chemical engineering, food, and pharmaceuticals.
The ability to adapt to fluids with different viscosities enables the gear metering pump to play an important role in various industries and different coating processes, broadening its application range.
Good Self-Priming Ability
The gear metering pump has a certain self-priming ability and can suck in fluids on its own without the need for external auxiliary devices, which simplifies the system design of the coating machine and reduces the equipment cost and complexity.
In some coating processes that require frequent starting and stopping, the good self-priming ability can ensure that the pump sucks in fluids quickly and stably, improving production efficiency.
Strong Material Compatibility
Special materials, such as stainless steel, Hastelloy, and titanium alloy, can be used for the parts in contact with liquids. They have good corrosion resistance and fluid compatibility, can adapt to various acids, alkalis, solvents, and corrosive chemical additives, etc., can prevent the pump body and components from being corroded and damaged, and extend the service life of the pump.
This material compatibility enables the gear metering pump to operate reliably in different chemical environments and coating processes, ensuring the stability and safety of the production process.
Simple and Compact Structure
The structure of the gear metering pump is relatively simple. It is mainly composed of gears, shafts, pump bodies, pump covers and other components. It has a small number of parts, simple and reliable seals, and is easy to install, maintain and repair, reducing the equipment maintenance cost and downtime.
Its compact structural design also enables it to be conveniently installed and used in coating machine equipment with limited space without occupying too much space.
Smooth Operation with Low Noise
The gears are manufactured with a double-arc sine curve tooth profile. Compared with involute gears, there is no relative sliding on the tooth profile surface during the meshing process, so the tooth surface has no wear, the operation is smooth, there is no trapped liquid phenomenon, the noise is low, the service life is long, and the efficiency is high. It can provide operators with a relatively quiet working environment and also reduce the vibration and wear during the operation of the equipment.
Linear Extrusion Characteristics
The conveying capacity of the gear metering pump has a basically linear relationship with the rotational speed, which is convenient for coordinating with upstream and downstream equipment, realizing the whole-process online monitoring and feedback control of the entire coating process, thus better meeting the requirements of automated production, and improving the controllability and intelligence level of the production process.
