Product Description

Rotary viscometer NDJ-1 Overview:
This viscometer is suitable for measuring the viscosity and rheological properties of various fluids, and can also measure mineral oils, lubricants, adhesives, paints, fuels, etc The dynamic viscosity and structural viscosity of ink are used to measure fluid viscosity in industries such as petrochemical products, daily chemical, pharmaceutical, food, fuel, adhesives, etc Ideal instrument.

The DJ-1 rotary viscometer has the following characteristics:
1. The lifting system adopts a helical rack/helical gear method:
Other domestic manufacturers of rotary viscometers use a straight rack/straight gear method, where the rack and gear only have one tooth in contact during operation
Easy adjustment on top; It will inevitably slide downwards, and if self sliding is avoided, it will be difficult to adjust upwards. Our factory's rotational viscometer adopts a helical gear method,
When the helical rack and helical gear work, there are three teeth in contact, effectively overcoming the shortcomings of the straight rack/spur gear method. It is convenient and easy to move up and down, and will not
Self sliding. (The helical rack/helical gear method is much more difficult to process than the straight rack/gear method in terms of cost requirements)
2. Universal joints have been added at the interface connecting the rotor:
Usually, the rotor of a rotary viscometer is directly rigidly connected to the rotating shaft, and the eccentricity of the shaft or rotor can cause the rotor to deform during testing
Shake, affecting testing accuracy. The rotating shaft tip is thin and sharp, and even accidental collisions can often cause bending or even damage to the shaft tip. Adopting
The universal joint can effectively reduce the testing error caused by the non concentricity of the shaft and rotor, and protect the shaft tip from damage caused by impact. This type of structure is widely used domestically
He doesn't have a manufacturer yet, he has only seen it on imported high-end viscometers (universal joints need to be processed with imported CNC machines, with very high accuracy requirements, so...)
This has also increased significantly.
3. The variable speed gear is made of high wear-resistant and high-performance engineering plastic pressed:
In order to ensure smooth operation and accurate measurement of the rotary viscometer, high precision is required for gear machining. Currently, other domestic manufacturers produce viscometers
The gears used are all machined from metal sheets and then riveted with other parts. Due to the limitations of this machining method, it is difficult to meet the design requirements,
Causing the viscometer to operate unevenly during operation, such as shaking, shaking, pointer jumping, etc., and producing loud noise. And our factory uses high-performance engineering plastics
(Its performance is superior to metal) The entire component of the gear is pressed into shape in one go, and the high precision of the mold ensures that the processed gear fully achieves
The design requirements fundamentally solve the problems caused by metal gears, making the viscometer work very smoothly and improving testing accuracy.
4. Fine processing and excellent performance:
Each component is meticulously processed and debugged, with strict quality control to ensure that users can purchase it happily and use it with confidence.
