Sample and chamber heating – The chamber is heated by an external helical element. Located at Chongqing city–a southwest electromechanical manufacturing center as well as national municipality, Chongqing TOP is a professional leading manufacturer and supplier of oil purifiers and various related testers.

Toggle navigation Toggle search. Adopts frequency control technology, digital display of all kinds of parameters 3. Basically, this test separates insolubles from the oil after it has been mixed with solvents. About the Author Sabrin Gebarin.

We consists of departments respectively for technological development, machinery manufacture, instrument manufacture, quality control etc. Safety features – A motor driven lid latch with a safety interlock to prevent centrifuge operation while the lid is unlocked. It uses a single chip microcomputer control system, man-machine friendly operation interface 2. In addition to the materials separated by using Procedure A, this coagulation procedure separates some finely divided materials that may be suspended in the oil.

Acidity tester ACDI 3. The Oil Test Centrifuge is a microprocessor controlled, programmable, heating centrifuge that meets the above standards. TOP Oil Purifiers are widespread in the fields of electric power, petrifaction, mineral, shipbuilding, steel construction, bridge, automobile and railway, playing a great role in reducing energy consumption for clients as well as environmental pollution.

Setafuge Hazard Reduction System The optional Setafuge Hazard Reduction System prevents the uncontrolled release of hazardous vapours from the centrifuge.

Recently, an engine oil sample was tested to determine the root cause of a failure that resulted in an engine seizing. Vapour extracted is diluted with air, and is safely discharged into a non-hazardous area. Strategies to Protect Grease Fittings from Contaminants. The instrument is sensitive to the weight of the samples and an imbalance detector stops the centrifuge if the rotor head has an imbalance of over 8 grams.


Chongqing Top Oil Purifier Co. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ICS Number D839 Has programmable operation program which can be arbitrarily set for the lifting speed, automatic calculation of RCF value, 4.

The toluene dissolves organic oxides, but not soot. When the sample was atm, the soot was moved along the side of the test tube instead of being forced to the bottom with the other insolubles. Common causes of engine oil thickening include highly oxidized oil, glycol contamination, thermal degradation and severe soot contamination.

Although more expensive in certain astmm, these tests are more appropriate for measuring soot than pentane and toluene insolubles by centrifuge. We d93 you with reliable oil purifiers such as transformer oil purifier, turbine oil purification machine, hydraulic oil purifier, lubricating oil filtration machine, fuel oil restoration, oil and water separator, oil regeneration equipment, waste oil recycling equipment etc.

To understand why the results of the pentane and toluene coagulated insolubles test did not coincide with TGA and membrane filtration tests, it is important to know how each test is performed and understand the underlying theories.

ASTM D – 05 Standard Test Method for Insolubles In Used Lubricating Oils

This is further supported by the fact that the soot passed through a 0. It provides an indication of the materials asym can readily be separated from the oil-solvent mixtures by centrifuging. Therefore, test results indicated a low insolubles reading. Initial analysis of the oil sample revealed that the oil was relatively new additive elements were astk to the reference oilit did not appear to be oxidized reasonable acid numberand there was no sign of glycol contamination or wrong oil added no unusual additive elements were present in the used oil that did not show up in the reference oil.


The first test was conducted using a 0. Contact Supplier Start Order. The TGA method involves placing the sample in an oven, where it is weighed continuously as the temperature is increased at specific increments.

You can set the rotation speed, temperature, acceleration rate and time using the control panel. Not exactly what you want? Flash point tester open cup TPO When the weight stabilizes and remains stable for a certain duration, this signifies that all the oil has evaporated and only insolubles remain.

Service Commitment – TOP bring you prompt, considerate and professional aftersale service and technical support, and explore technology future together. Instrument is equipped with a variety of safety protection, such as imbalance, over temperature, over speed, door cover and so on. Click here for 6-place Centrifuge.

Note 1 Results obtained by Procedures A and B should not be compared since they usually give different values. First, a pentane solvent is mixed in with the oil to separate solids and oxidation products from the oil by lowering the viscosity. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Operation – You operate the lid using the control panel.
