PND176 Petroleum Product Condensation Point and Pour Point Tester

The pour point pour point analyzer for petroleum products is produced using imported Japanese technology and complies with GB/T 510. This instrument adopts the principle of compressor refrigeration, a closed bath, equipped with a tilt bracket and tilt point sleeve, and is equipped with an intelligent digital display controller. It is easy to use and reliable in quality. The instrument adopts fuzzy control principle and PID self-tuning technology, with stable and reliable control performance, and is the preferred testing instrument in the laboratory.
The refrigeration system of this instrument consists of a compressor, a filter, a capillary choke, an evaporator, and various connecting pipelines. The refrigerant absorbs heat and expands through the evaporator, and the expanded gas is compressed by the compressor into the exhaust pipeline to form high-temperature and high-pressure gas, which then enters the condenser to cool into liquid. Then, it is throttled and depressurized by the capillary tube and enters the evaporator to evaporate and absorb heat, achieving the purpose of refrigeration. After the refrigerant evaporates, it is compressed by the compressor into the exhaust pipe and enters the condenser, thus working repeatedly to achieve cyclic refrigeration. The temperature control system is controlled by an intelligent digital temperature controller through PID adjustment to achieve fixed-point temperature control. The control signal output by the temperature controller triggers the solid-state relay, causing the heating tube to work and counteract the cooling capacity generated by the compressor refrigeration system, keeping it constant at the temperature we need.

PND176 petroleum products pour point analyzer
The determination of the pour point of the pour point of the petroleum products is produced by the introduction of advanced technology from Japan, according to GB / T 510. The instrument uses a compressor refrigeration principle, enclosed bath with tilt stand and pour point sets, and is equipped with intelligent digital display controller, easy to use, reliable quality, the instrument uses fuzzy control principle and PID self-tuning technology, control performance stable and reliable, is the the laboratory preferred test instrument.
The refrigeration system is the instrument by the compressor, filter, capillary restrictor, connected to the evaporator and the piping components. Endotherm of the refrigerant through the evaporator expansion pressure by the compressor, the expansion of the gas after the formation of high temperature and high pressure gas into the exhaust pipe and then into the condenser cooling into liquid, and then by capillary throttling into the evaporator evaporation endothermic to achieve refrigeration purposes . Compressor pressure refrigerant evaporates then into the exhaust pipe into the condenser, so the cycle refrigeration cycle to work. The temperature control system is noticeable by the intelligent digital temperature control device PID adjustment to achieve the fixed-point temperature control, temperature control device output control signal to trigger solid-state relays, heating pipe work offset compressor refrigeration system to produce cold it constant in on the required temperature.
