Detailed description of the invention
As it is shown in figure 1, one fuel oil switched system of the present invention, including heavy oil/diesel oil modular converter, this module, based on the oil product required for trading limit, controls heavy oil storehouse and diesel oil storehouse output heavy oil or diesel oil.Heavy oil/diesel oil modular converter mainly includes heavy oil/diesel oil conversion control circuit and heavy oil/diesel oil delivery valve.Fuel oil tank includes that the fuel oil output in heavy oil storehouse, diesel oil storehouse and low-sulfur diesel-oil storehouse, diesel oil storehouse and heavy oil storehouse needs through heavy oil/diesel oil delivery valve.Heavy oil/diesel oil modular converter controls heavy oil/diesel oil delivery valve by heavy oil/diesel oil conversion control circuit, it is achieved fuel oil tank output heavy oil or diesel oil.
Diesel oil/low-sulfur diesel-oil modular converter, this module is based on the oil product required for trading limit, control diesel oil storehouse and low-sulfur diesel-oil storehouse output diesel oil and the ratio of low-sulfur diesel-oil, it is achieved fuel oil tank oil product output is switched to low-sulfur diesel-oil by diesel oil or switched to diesel oil by low-sulfur diesel-oil.Diesel oil/low-sulfur diesel-oil modular converter mainly includes diesel oil/low-sulfur diesel-oil conversion control circuit and diesel oil/low-sulfur diesel-oil delivery valve.Fuel oil output in diesel oil storehouse and low-sulfur diesel-oil storehouse needs through diesel oil/low-sulfur diesel-oil delivery valve.Diesel oil/low-sulfur diesel-oil modular converter controls diesel oil/low-sulfur diesel-oil delivery valve by diesel oil/low-sulfur diesel-oil conversion control circuit and opens and aperture.During diesel oil switches to low-sulfur diesel-oil, from the initial all diesel oil of Oil Fuel Tank oil product output, progressively transition is diesel oil and low-sulfur diesel-oil mixing, then to final all low-sulfur diesel-oils；During being switched to diesel oil by low-sulfur diesel-oil, from the initial all low-sulfur diesel-oils of fuel tank oil product output, progressively transition is low-sulfur diesel-oil and diesel oil mixing, then to final all low-sulfur diesel-oils.
At diesel oil in low sulfur oil handoff procedure, if the phenomenon such as atomization may be caused to occur because of the viscosity of low-sulfur diesel-oil is too low switching initial stage diesel oil/low-sulfur diesel-oil delivery valve aperture is unreasonable, cause main frame and electromotor to occur body inner high voltage oil pump is stuck and cisco unity malfunction.In order to better control over the aperture of diesel oil/low-sulfur diesel-oil delivery valve, fuel oil switched system of the present invention adds diesel oil/low-sulfur diesel-oil temperature mixing measurement module.The detection of this module, through fuel oil transportation by lighter module transportation by lighter, enters the temperature of the fuel pipe intermediate fuel oil before main frame and electromotor, and the fuel oil temperature information collected is sent to diesel oil/low-sulfur diesel-oil conversion control circuit as electronic signals.Diesel oil/low-sulfur diesel-oil conversion control circuit receives the fuel oil temperature information that diesel oil/low-sulfur diesel-oil temperature mixing measurement module sends, and calculates the unit interval variable quantity of fuel oil temperature.During diesel oil switches to low-sulfur diesel-oil, diesel oil/low-sulfur diesel-oil conversion control circuit calculates the temperature reducing rate in the fuel oil temperature unit interval, and ensures that temperature reducing rate is less than or equal to a-b/T1, otherwise the aperture of diesel oil/low-sulfur diesel-oil conversion control circuit control diesel oil/low-sulfur diesel-oil delivery valve strengthens diesel fuel ratio in fuel oil tank oil product output；Low-sulfur diesel-oil is in diesel oil handoff procedure, and diesel oil/low-sulfur diesel-oil conversion control circuit calculates the temperature ramp-up rate in the fuel oil temperature unit interval, and ensures that temperature ramp-up rate is less than or equal to a-b/T2, low-sulfur diesel-oil ratio during otherwise diesel oil/low-sulfur diesel-oil conversion control circuit controls the oil product that diesel oil/low-sulfur diesel-oil delivery valve increasing fuel oil tank exports.Wherein, when a is all diesel oil in the fuel pipe before entering main frame and electromotor, the fuel oil temperature that diesel oil/low-sulfur diesel-oil temperature mixing measurement module records；When b is all low-sulfur diesel-oils in the fuel pipe before entering main frame and electromotor, the fuel oil temperature that diesel oil/low-sulfur diesel-oil temperature mixing measurement module records；T1For ensureing under main frame and electromotor normal running conditions, the shortest time that diesel oil is changed to low-sulfur diesel-oil；T2For ensureing under main frame and electromotor normal running conditions, the shortest time that low-sulfur diesel-oil is changed to diesel oil.
Fuel oil transportation by lighter module, the fuel oil that Oil Fuel Tank is exported by this module is lightered, and provides for main frame and electromotor and uses the pressure needed for oil product and flow, it is achieved controls heavy oil and bavin oil viscosity.This module is mainly lightered control circuit, lift pump, booster pump and viscosity controller by fuel oil and is formed.Required fuel pressure and flow are realized by lift pump and booster pump, and heavy oil and bavin oil viscosity control to be realized by viscosity controller.When fuel oil transportation by lighter module breaks down, backup diesel pump then provides fuel delivery for main frame and electromotor.
Fuel oil switched system can arrange separate unit electromotor fuel oil handover module, and this module mainly realizes separate unit electromotor and uses oil product to change between heavy oil and diesel oil and between diesel oil and low-sulfur diesel-oil.This module mainly includes separate unit electromotor fuel oil control switching circuit, separate unit electromotor fuel oil transfer valve and separate unit electromotor fuel oil delivery valve.The opening and closing of separate unit electromotor fuel oil control switching circuit control separate unit electromotor fuel oil transfer valve realize the switching of separate unit electromotor fuel oil.In the case of need not whole electromotor fuel oils are switched, it is achieved the switching of separate unit electromotor oil product.Furthermore it is also possible to arrange remote pilot module, this module mainly realizes main frame and the remote pilot of electromotor fuel oil switching.
