Background technique
As the existing the highest engine consumption measuring equipment of precision, mass flow rate formula fuel consumption meter has adopted up-to-date scientific and technological Coriolis(Coriolis-type) technology, owing to utilized temperature or pressure change can not influence the principle of measurement of quality, so mass measuring method is the most accurate method of flow measurement.Be different from needs and wait for the weight method and the volumetry in tens seconds, the Coriolis-type fuel consumption indicator has been realized continuous measurement truly, and test period and testing expenses have been saved in oil-filled pause in the middle of no longer needing greatly.
Coriodis mass flow meter (hereinafter to be referred as CMF) is the core component of whole mass flow rate fuel consumption meter, but there is quite a few CMF design current velocity very high, can produce the bigger pressure loss, the pressure loss of some model C MF even specific volume formula instrument are big by 100%.Can cause bigger pressure loss problem in fuel consumption meter inside at the CMF mass flowmenter, can increase a fuel pump in the flowmeter upstream usually and be used for remedying this pressure loss.
The fuel oil supply system that uses in the present engine testing field, all adopt fuel pump energising DFF Direct Fuel Feed formula, but can't discharge because the fuel pump continuous firing produces a large amount of heats, often cause fuel pump to be burnt at last, thereby have a strong impact on the working life of fuel pump.
The model utility content
The purpose of this utility model is to overcome existing fuel consumption meter fuel oil supply system fuel pump short defective in working life, a kind of intermittent type oil supplying device is provided, improve the working life of fuel pump, a kind of mass flow rate formula fuel consumption meter that uses this intermittent type oil supplying device is provided simultaneously.
For achieving the above object, the technological scheme of the intermittent type oil supplying device that the utility model provides is as follows: a kind of intermittent type oil supplying device, comprise oil-feed exhaust box and oil feed line, described oil feed line is provided with fuel pump, and the fuel pump downstream is provided with successively by other respectively accumulator and the pressure transducer that is connected on the oil feed line of bypass line.
Link to each other by fuel-displaced pneumatic control valve between described oil-feed exhaust box and the oil feed line.
The technological scheme of the mass flow rate formula fuel consumption meter of this intermittent type oil supplying device of the use that the utility model provides is as follows: a kind of mass flow rate formula fuel consumption meter that uses the intermittent type oil supplying device, comprise intermittent type oil supplying device and measuring device, described intermittent type oil supplying device comprises oil-feed exhaust box and oil feed line, described oil feed line is provided with fuel pump, and the fuel pump downstream is provided with successively by other respectively accumulator and the pressure transducer that is connected on the oil feed line of bypass line; Described measuring device comprises mass flowmenter, and links to each other with described oil feed line.
Be respectively equipped with internal pressure regulator and outlet oil pressure regulator before and after the described mass flowmenter.
Also be provided with the shut-off valve that is used to demarcate zeroing behind the described mass flowmenter.
Link to each other by fuel-displaced pneumatic control valve between described oil-feed exhaust box and the oil feed line.
The utility model is according to the handling characteristics and the performance of fuel pump in the mass flow rate formula fuel consumption meter, accumulator and pressure transducer have been increased, overcome the easy defective that is directly burnt out or have a strong impact on its working life of fuel pump continuous firing, make fuel pump also can provide enough fuel deliveries for system without continuous firing, thereby improved the stability and the working life of fuel oil pump performance greatly, also guaranteed the functional reliability and the stability of fuel consumption meter system simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model intermittent type oil supplying device;
Fig. 2 is the structural representation of the utility model mass flow rate formula fuel consumption meter.
Embodiment
Be illustrated in figure 1 as the structural representation of the utility model intermittent type oil supplying device, comprise oil-feed exhaust box and oil feed line, described oil-feed exhaust box comprises filler opening 1, filter screen 2 and oil outlet 5, described exhaust box top is higher than the filter screen place and is provided with ball float 3, is provided with relief opening 4 with the exhaust box top of float corresponding section; Be provided with fuel-displaced pneumatic control valve 6 and fuel pump 7 on the described oil feed line successively, the fuel pump downstream is provided with successively by other respectively accumulator 8 and the pressure transducer 9 that is connected on the oil feed line of bypass line.
The working procedure of the utility model intermittent type oil supplying device is as follows: after the fuel oil of main in-line is discharged bubble by the oil-feed exhaust box, enter oil feed line from oil outlet 5, because the vibration of traditional fuel pump can exert an influence to the precision of quality flow type sensor, increased accumulator 8 behind the fuel pump 7 to eliminate pulse and vibration, to also have a function be exactly after the main power source of oil circuit quits work to accumulator in addition, and it can be used as auxiliary power source and provides of short duration fuel delivery for system.Because master's oil feed pump should add the pressure of 4bar in advance in the mass flowmenter upstream when being connected use with mass flowmenter, therefore a pressure transducer 9 is set behind accumulator, the output power of utilizing the SC sigmal control fuel pump on the pressure transducer is to accomplish the end in view.
The adjusting of fuel pump obtains by two different working modes: (1) pump delivery intermittently, keep system pressure by accumulator; (2) regulate (big flow) continuously, the state of pump is continuous running.When the required fuel flow of motor was not too big, fuel pump was in step working state by the SC sigmal control of pressure transducer, thereby improves greatly the working life of fuel pump.
The structure of the fuel consumption meter of the employing intermittent type oil supplying device that the utility model provides as shown in Figure 2, comprise intermittent type oil supplying device and measuring unit, described intermittent type oil supplying device comprises oil-feed exhaust box, fuel-displaced pneumatic control valve 6 and fuel pump 7, other successively accumulator 8 and the pressure transducer 9 of having connect on the oil feed line behind the described fuel pump 7; Described measuring unit comprises internal pressure regulator 10 and the outlet oil pressure regulator 13 that mass flowmenter 11 and front and back thereof are provided with, and also is provided with the shut-off valve 12 that is used to demarcate zeroing usefulness behind the described mass flowmenter.
The working procedure of mass flow rate formula fuel consumption meter of the present utility model is as follows: after the fuel oil of main in-line is discharged bubble by the oil-feed exhaust box, enter mass flowmenter 11 and measure under the control of intermittent type oil supplying device, the fuel oil constant voltage enters motor under the adjusting of outlet oil pressure regulator subsequently.Because the regulating action of accumulator 8 and pressure transducer 9, fuel pump can be realized intermittent type and continuous two kinds of working staties, promptly when the required fuel flow of motor is not too big, fuel pump is by the SC sigmal control of pressure transducer, be in step working state, thereby improve greatly the working life of fuel pump.
Oil supplying device of the present utility model is ingenious to have utilized required component---accumulator in the mass flow rate formula fuel consumption meter equipment, and in conjunction with pressure transducer, designed step fuel oil supply system, thereby improved the working life and the working stability of fuel pump, also improved the functional reliability of whole fuel consumption meter system greatly.
