The equipment is equipped with imported intelligencePIDTemperature controller and high precisionKType thermocouple sensor for precise temperature control. Temperature range coverage+20℃~200℃, instrument display accuracy reaches0.1℃, control the uniformity of oil temperature within ±1Within ℃, it can meet the strict temperature accuracy requirements for oil resistance testing of various materials.3000WThe spiral tube heater provides a stable heat source for the temperature control system, with a smooth heating rate to avoid local overheating and test data deviation.

2. Structure and Material Characteristics

The device volume is400×530×550mmCompact design suitable for limited laboratory space; The inner and outer boxes are made of stainless steel material, which has excellent oil and corrosion resistance and can be in long-term contact with various testing oil media, effectively extending the service life of the equipment. At the same time, equipped with a38mm×300mmStainless steel dumbbell shaped sample cups, corrosion-resistant material sample plugs, and other accessories further enhance the adaptability of testing.

3. Time and Operation Control

support999.99H/M/SMultiple unit time settings, flexible adjustment of test duration according to different testing standards; built-in40WThe cyclic stirring method of stirring power ensures uniform temperature of the oil medium and guarantees the reliability of the test results.

2、 Design of Security Protection System

DK-00371AA double-layer protection mechanism has been constructed to address the safety risks of high-temperature oil testing:

1. Liquid level protection: When the liquid level of high-temperature heat transfer oil is lower than the set value, the equipment automatically cuts off the heating program to prevent dry burning and damage to the heater from the root;

2. Overtemperature protection: When the temperature exceeds the set threshold, the system automatically cuts off heating and stops running, while triggering high-temperature overflow protection to prevent sample damage or equipment failure caused by temperature loss of control.

3、 Industry application and testing value

1. Applicable fields

This device is mainly used for oil resistance testing of wire and cable, rubber, and plastic insulation materials. It can simulate the high-temperature oil medium environment of materials in actual working conditions, test their deformation, aging, mechanical performance changes, and other indicators.

2. Testing Methods and Value

During testing, place the sample in hot oil at a constant temperature and test its tensile strength and other performance parameters after removal. If it is a wire sample, its insulation quality can be further evaluated. This test provides quantitative data support for material formula optimization and product quality control, and is an important testing method in the research and production process of industries such as wire and cable, automotive parts, etc.

4、 Summary

DK-00371AThe constant temperature oil resistance testing machine effectively meets the diverse needs of material oil resistance testing through precise temperature control technology, reliable safety protection, and flexible operation design.
