An energy-saving and environment-friendly intelligent constant temperature fuel filter

Abstract

The invention relates to the technical field of filters, in particular to an energy-saving and environment-friendly intelligent constant-temperature fuel filter, comprising a casing, a waste heat utilization regulating valve, a temperature sensor and a temperature controller. The casing is provided with an input channel, an output channel, a The hot oil inlet channel and the hot oil outlet channel are respectively connected with the hot oil outlet channel and the input channel. The waste heat utilization regulating valve is used to adjust the flow of the hot oil inlet channel to the hot oil outlet channel or the input channel. The temperature sensor is used for In order to detect the oil temperature, the temperature controller is used to control the action of the waste heat utilization regulating valve according to the oil temperature detected by the temperature sensor. The invention can not only satisfy the regulation and control of waste heat utilization using 0# diesel oil, but also use other grades of low temperature resistant diesel oil, which can not only adjust the waste heat of the engine to make full use of it, but also control the oil temperature within the optimal working range, preventing the The high temperature, reduced density and loss of viscosity of low-temperature diesel cause secondary damage to the engine.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to an energy-saving and environment-friendly intelligent constant temperature fuel filter. Background technique [0002] With the improvement of the performance of diesel engines, the requirements for the performance indicators of fuel filters are becoming more and more stringent. However, the diesel density is affected by the low temperature and the performance of the engine is greatly attenuated. Performance, oil-water separator performance, and impurity filtration performance are the main causes of engine flexibility in cold use, high mechanical wear, short life, and poor power performance, and indirectly affect engine fuel consumption and emissions. [0003] In recent years, there have been "electrically heated oil-water separators", "heat-sensitive metal strip temperature-controlled oil-water separators" and "thermal reuse oil-water separators" in the market. Insufficient fuel...

Problems solved by technology

It can be seen that if the waste heat of the engine is controlled by the thermal actuator to heat the low-temperature resistant cold diesel oil, when the temperature of the three low-grade diesel oils rises above -10°C, -25°C, and -35°C respectively, due to the heat-sensitive wax in the thermal actuator The temperature required for expansion cannot be reached, so the thermal actuator cannot close the oil return channel and the heat reuse channel, which will cause the three grades of diesel oil to be severely insufficient in density due to excessive temperature, which will not only cause engine power attenuation, but also cause oil Diesel oil loses viscosity due to high temperature, which greatly reduces the service life of the fuel injection parts of the engine and brings serious harm to the engine in use
