1. Lifting system using oblique rack / bevel gear mode: other domestic manufacturers are used in a rotational viscometer straight rack / spur gear mode, rack and pinion gear at work, only a touch, if easily adjust upward; must be to Under self-slippery, such as avoiding since the sliding upward adjustment will be difficult. I plant surface rotational viscometer method is the use of helical gears, helical rack and helical gear teeth when working with three contacts, effectively overcome the straight rack / spur gear the disadvantage, easy to move up and down easily, and will not slip from . (Oblique rack / helical gears manner than on the cost of processing requirements straight rack / gear mode is much more difficult) 2. At the interface connecting the rotor increases the universal joint: rotational viscometer is usually the axis of rotation of the rotor is rigidly connected directly to the shaft of the rotor misalignment or misalignment will cause the rotor in the test shaking, affect test accuracy. Thin and sharp tip rotation axis is often inadvertently cause the collision axis sharp bend or even damage. After using a universal interface, which can effectively reduce the rotor shaft and the heart to bring different measurement errors, and to protect the shaft tip from impact and damage. This structure other domestic manufacturers have not only imports of high-grade viscometer seen (universal joints required imported CNC machining, precision is very high, so the cost is also increased a lot). 3. Gear high wear resistance, high-performance engineering plastics pressed: In order to smooth running rotary viscometer, measurement accuracy, precision machining of the gear is very high. Currently viscometer other domestic manufacturers are used in the gear teeth with a piece of metal sheet and then processed into other parts riveting, because the limitations of this processing method, it is difficult to meet the design requirements, making the viscometer at work is not running smoothly, such as jitter, shake, pointer jumping, etc., and noise. And I plant using high-performance engineering plastics (its performance is better than metal) the entire part of the gear once pressing, because of the mold so as to ensure high-precision machined gear fully meet the design requirements, from the fundamental solution to the metal gears with to the problems, making viscometer at work is very smooth, improving accuracy of the test. 4. Fine processing, excellent performance: each component is carefully processed, well testing, strict quality control, as is the user happy to buy, rest assured that use. | |
