Overall requirements:
According to the ISO 12156.1-2018 ASTM D6079-2018 test method, used for the lubrication performance evaluation test of diesel engine fuel(including diesel fuel containing lubrication performance modifiers). The operation of the automatic constant temperature and humidity system is simple and easy, and the corresponding control area can be activated by clicking on the main control interface. No other operation steps are required. After the test is completed, the sampling data in the experimental process is closed and stored, and the operator's operation steps are reduced. Increased efficiency.

compression mechanism cold constant temperature system:
(1) The cold constant temperature and humidity system with compression mechanism has the obvious advantages of fast refrigeration speed and high efficiency. At the same time, it is an independent control unit. The selection of a temperature constant humidity box with appropriate specifications can be used to control the temperature and humidity of other instruments. The control accuracy is 0.1. The instrument is automatically controlled throughout the entire time. After the customer sets it, the instrument executes the equipment order and controls the temperature and humidity in the box.
(2) Operating ambient temperature(in the test host box): 0 to 50 °C, control accuracy 0.1 °C; The factory setting is 23 ± 0.1 °C, and customers can also set up their own according to actual needs. Operating environmental humidity(in the test host box): 5-95 % R.H. range adjustable, display accuracy 0.1; The factory setting is 53 % ± 1 %, and customers can also set up their own according to actual needs.
(3) Compression mechanism cold constant temperature and humidity system: This system consists of a constant temperature and constant temperature and humidity control instrument. The two parts use a split type connection to avoid the resonance of the test machine mechanical system due to the high frequency vibration of the compressor and gas pump.
(4) The system fully meets the requirements of the latest version of the international diesel lubricating high-frequency reciprocating test machine(HFRR),(standard number: ISO 12156.1-2018 ASTM D6079-2018) for test temperature and humidity control
