Product features
1. There is no residual adhesive drawing phenomenon at the front end of the needle
Spiral structure design, freely adjustable forward and reverse to achieve suction function, completely solving the problem of wire drawing and residual glue in the medium;
The constant volume screw pump does not produce pulsation during transportation and does not have any shear effect on the medium, so it will not have any impact on the char acteristics of the medium;
3. Not affected by liquid level and viscosity changes
Changes in medium liquid level and viscosity will not affect the conveying accuracy of the screw valve, thus avoiding frequent adjustment of dispensing parameters;
4. Medium containing particulate matter can also be quantitatively transported
The will not cause damage to particles when conveying high solid content media;
5. Easy to clean and replace
The screw valve has a simple structure and can be easily cleaned and replaced with acce ssories without affecting production;
6. A relatively simple feeding method
Different feeding methods can be applied, as long as a certain pressure can be ensured
to allow the medium to enter the inlet of the screw valve, without the need for frequent
adjustment of feeding parameters.

The screw valve is suitable for conveying small flow media and adopts an eccentric spiral structure design. By rotating the rotor around the axis in the stator cavity, the closed cavity glue formed between the screw and the stator is continuously distributed along the rotor thread lineEvenly and consistently discharge. The conveying process does not produce shear effects on t he medium, therefore it will not have any impact on the properties of the medium. At the same time, the medium suction function can be easily achieved by reversing the motor, ensuring the medium andThe cleanliness of the material completely solves the problems of medium leakage and wire drawing. | |||||
The high application screw valve is a high-precision volumetric quantitative conveying pump, which can achieve the required precision flow output by simply controlling the motor speed. It is widely used in various high-precision quantitative conveying situations. Suitable for various types of mediaConveying: fluids with various viscosities such as glue, grease, oil, paint, adhesive s, silicone resins, and highly abrasive media. | |||||

Optical bonding (adhesive dispensing to obtain better image data), conformal coating (comprehensive application of a protective paint), damming & filling (protection of highly complex areas), top sealing (precise dispensing to provide reliable protection), bottom filling (conductive adhesive dispensing), micro dispensing (high precision dispensing of liquid materials) and packaging (dispensing of packaging compounds in electronic industry) | |||||
(1) The maximum conveying pressure and self-sealing property decrease with the decrease of viscosity and increase with the increase of viscosity. Please consult the for details. | |||||
(2) The accuracy of dispensing is related to the absolute deviation of the materials delivered by the dispensing pump once rotating. Depending on the viscosity transported material. | |||||
