One-component screw valve-eccentric wheel series

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.

be applied to
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.
