NDJ-1 Rotational Viscometer overview

JinKeLian NDJ-1 Rotational Viscometer is a Rotational Viscometer that displays the measurement value through a pointer. The measured paint viscosity range is 10~100000mPa·s, and the measurement error is ±5%. The NDJ-1 Rotational Viscometer is equipped with 4 spindles and provides 4 rotation speeds, which can be combined into 16 types, suitable for measuring different viscosity ranges.

NDJ-1 Rotational Viscometer is a new instrument used to measure liquid viscosity. It is widely used to measure the viscosity of various fluids such as grease, paint, plastics, food, adhesives, etc.

Advantages of NDJ-1 Rotational Viscometer

1. The lifting system adopts helical rack/helical gear method:

Other Rotational Viscometers in CHINA use spur rack/spur gear method. Only one tooth of the rack and gear contacts during operation. If you adjust it upward easily, it will slide downward. If you avoid self-slip, adjust upward and it will slide. difficulty. The NDJ-1 Rotational Viscometer uses a helical gear. When the helical rack and helical gear work, there are three teeth in contact, which effectively overcomes the shortcomings of the spur rack/spur gear method. It is convenient and easy to move up and down without self-slip. . (The helical rack/helical gear method is much more difficult than the spur rack/gear method in terms of processing cost.)

2. A universal joint is added to the interface connecting the rotor:

Usually, the rotor of a Rotational Viscometer is directly and rigidly connected to the rotating shaft. The misalignment of the shaft or the rotor will cause the rotor to shake during testing and affect the testing accuracy. The tip of the rotating shaft is thin and pointed, and even an inadvertent collision often causes the tip of the shaft to bend or even be damaged. The use of a universal interface can effectively reduce test errors caused by the non-concentricity of the shaft and rotor, and protect the shaft tip from damage due to impact. This kind of structure has not been found in other domestic (CN) manufacturers, and has only been seen in imported high-end viscometers (the universal joint needs to be processed by imported CNC machine tools, and the accuracy requirements are very high, so the cost has also increased a lot).

3．The transmission gear is made of highly wear-resistant and high-performance engineering plastics:

In order to make the Rotational Viscometer run smoothly and measure accurately, the machining accuracy of the gear is very high. At present, the gears used by other domestic (CN) manufacturers to produce viscometers are processed from metal sheets into toothed plates and then riveted with other parts. Due to the limitations of this processing method, it is difficult to meet the design requirements, making the viscometer run unstable during operation. Such as jitter, shaking, pointer jumping, etc., and loud noise. Our factory uses high-performance engineering plastics (whose performance is better than metal) to press and mold the entire component of the gear at one time. Due to the high precision of the mold, it ensures that the processed gear fully meets the design requirements, fundamentally solving the problem of metal gear belts. This problem makes the viscometer very stable when working and improves the test accuracy.
