hths machine engine oil

HK-0703 High Temperature High Shear Rate Viscosity Tester (hths machine engine oil)Complies with ASTM D5481 Standard Test Method for Measurement of Apparent High Temperature and High Shear Rate Viscosity by Multicell Radial Viscometer It covers the laboratory determination of High Temperature Viscosity (HTHS is an oil laboratory equipment) for oil Engine at 150 ℃ using a multi-cell capillary viscometer containing pressure, temperature and timing instruments.

The shear rate of this test method corresponds to an apparent wall shear rate of 1.4 million alternating seconds (1.4 3 106s-1). It has been found that this shear rate reduces the discrepancy between this test method and other high temperature hihg-shear test methods used for motor oil specifications. Viscosity is determined directly from titrants created with Newtonian oils with viscosities from 2 to 5 MPa at 150 ℃.

I. Main Technical Features

1. The instrument is powered by an external computer for Windows system, and the internal program is controlled

By industrial grade PLC, the system is stable.

2. The instrument is equipped with intelligent digital display temperature controller, which has high temperature control accuracy,

Strong anti-interference ability and long service life.

3. The heating part of the instrument is made of aluminum alloy, and the aluminum heating belt is in close contact with

Viscometer tube, which is evenly heated and has good thermal insulation effect. Pressure detection part is precision

Pressure sensor imported from the United States, the data is accurate and reliable.

4. In the experiment process, after entering the test interface, select the appropriate pressure, and then inject the sample,

Then withdraw the excess sample after 15 minutes. Click start, the instrument automatically measures the pressure,

The time is automatically calculated. After completing the experiment, the result is automatically calculated by the internal

Program account. The tool is highly automated and easy to use.

5. Each pilot unit of the instrument is calibrated with four American standard oils before leaving the factory.

The experimental data is accurate and reliable.

6. The experiment is equipped with an external U disk, which can import the experimental data of the current system into

U disk. It is convenient to transfer data.

7. The instrument is equipped with a special pressure reducing valve to help the user connect the cylinder and operate.
