Description
Technical field
The utility model relates to a kind of fuel oil equivalent metering regulating system.
Background technology
In recent years, China's foreign-going ship boiler-burner need change when stopping the industrially developed country port and burnt low-sulfur, low-viscosity (40 ℃ the time 1.4 * 10
-6m
2/ s) fuel oil (be Marine Gas Oil, be abbreviated as MGO) burns light diesel fuel (MDO) or heavy oil (HFO) in other zones.Usually MDO is 8 * 10 at 20 ℃ of lower viscositys
-6m
2/ s, 90 ℃ of lower HFO viscositys are about 70 * 10
-6m
2/ s.Because the atomizing viscosity difference of MGO, MDO and HFO is very large, when using same fuel quantitative pump to the burner fuel feeding, the output quantity difference of three kinds of fuel oils can reach 20%～45%.Make burning load, fired state produce very great fluctuation process, worsened combustion conditions, even cause boiler just not move.Simultaneously, other burners are equipped with baroque fuel flow meter regulating valve, and degree of regulation is poor, and manufacturing cost is high.

Compared with prior art the utlity model has following advantage.
Due to the structural design that has adopted fuel oil type viscosity selector and frequency conversion oil pump, thereby solved the problem that when larger the variation occurs the fuel oil viscosity, the metering of fuel flow equivalent is regulated.Have the stability of fuel oil state and the characteristics of reliability, and degree of regulation is high, cost is low.To MGO, MDO and HFO can realize fuel flow etc. mass metrology regulate, when oil kind (viscosity) changes, can guarantee stability and the reliability of fuel oil state.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is this apparatus structure principle schematic.
The specific embodiment
Comprise fuel quantitative pump 5, described fuel quantitative pump connects control device, as shown in Figure 1, described fuel quantitative pump 5 is the frequency conversion oil pump, described control device comprises signal controller, the signal controller input connects fuel oil type viscosity selector and oil burner Load Regulation signal, and the signal controller output connects fuel quantitative pump 5 through frequency modulator.
Described fuel quantitative pump 5 outputs were connected with check-valves through magnetic valve 1 through screw down nonreturn valve and are connected the fuel flow returns mouth in 4 minutes two the tunnel, the one tunnel; Is connected with magnetic valve through pressure regulator valve 2 and connects fuel outlet in another road.
Described fuel quantitative pump 5 oil-in front ends are provided with twin strainer 6.
1, architectural feature
The feature that this device is different from other fuel metering systems is: be provided with fuel oil type (viscosity) selector, can export different frequency upper limit value and lower limit value by frequency modulator to the fuel quantitative pump according to different fuel-viscosity variations, when fuel oil type (viscosity) changes, can be to the fuel oil of the quality such as fuel atomizer output.Frequency modulator is accepted simultaneously oil burner load and is produced conditioning signal, and regulating frequency output between the frequency upper and lower limit realizes that with the oil mass of regulating fuel quantitative pump input fuel atomizer the equivalent of burning load regulates automatically.And do not establish the fuel flow control valve in device.
Primary structure comprises the compositions such as fuel oil type viscosity selector, signal processor, frequency modulator, fuel quantitative pump and counterbalance valve.According to different fuel oil type viscosity, low, the ceiling value of two groups or more frequency output is set in frequency modulator, optionally be delivered to the fuel quantitative pump motor, change the high and low load different rotating speeds of fuel quantitative pump, the outgoing quality discharge capacity of different fuel oil type viscosity is equated.Frequency modulator is accepted oil burner load parameter conditioning signal simultaneously, and between frequency output upper limit value and lower limit value, regulating frequency output makes the fuel quantitative pump realize the equivalent metering adjusting of fuel oil.
The fuel quantitative pump is the frequency conversion oil pump, and under the certain pressure condition, its outgoing quality discharge capacity is directly proportional to rotating speed, and its rotating speed is directly proportional to supply frequency.The equivalent metering of fuel oil is regulated and is realized by the frequency conversion oil pump.
On fuel quantitative pump discharge pipeline, counterbalance valve is set, with its outlet pressure of adjusting.
2, operation principle
Let out in existing during due to the fuel quantitative pump work, under same rotational speed, the discharge capacity of different viscosity fuel oils there are differences; The viscosity difference is larger, and discharge capacity difference is just larger, thereby causes burner to be loaded with sky, combustion than lacking of proper care.But the fuel oil pump delivery is directly proportional to rotating speed, and rotating speed is directly proportional to the electric electromechanics source frequency, therefore can control the fuel oil pump delivery by changing supply frequency.By the viscosity of different fuel oils, set frequency modulator frequency output upper limit value and lower limit value (high viscosity is adopted than small frequency, low viscosity is adopted upper frequency), thereby the quality discharge capacity without fuel oil type (viscosity) fuel oil is equated.
In running, with oil burner load parameter conditioning signal input signal processor, signal exports frequency modulator after treatment again to, the output that makes frequency modulator thereon, the variation with the load parameter signal between lower limit changes, thereby by changing the constant displacement pump rotating speed, realize the equivalent metering adjusting of fuel oil, and need not to use the fuel flow meter regulating valve.
