Abstract
A diesel engine consumption meter comprises two elliptic gear flow sensors, a hall speed probe, a data cord, a display and an intra-car power supply. A middle seal plate is disposed between the two elliptic gear flow sensors. The elliptic gear flow sensors are fixedly connected to the middle seal plate through screws to form a sandwiched-plate overall structure. The double-head combined hall speed sensor is inserted into the middle seal plate and connected with the display through the data cord. The display is connected with the intra-car power supply through a power cord. An inlet tube and a return tube of a diesel engine are communicated with the two elliptic gear flow sensors respectively. A normally closed electromagnetic valve is added to one elliptic gear flow sensor. The diesel engine consumption meter has the advantages that the inlet tube and the return tube are monitored at the same time, displaying and searching are facilitated, and the diesel engine consumption meter is widely applicable.
Description
Technical field
The present invention relates to a kind of flowrate measuring tool, especially a kind of oil mass metering device of diesel motor.
Background technology
Diesel motor is one of topmost engine in the fields such as various vehicles, engineering machinery.In actual applications, be subject to the restriction of working condition or checkout equipment level, supervisor is difficult to the actual fuel oil situation of diesel motor to carry out accurate measurement and management and control.At present, in industry, conventional liquid flowmeter is oval gear flowmeter, oval gear flowmeter belongs to volumeter, in flow instrument, measuring accuracy is higher, but this type of oval gear flowmeter is only suitable for being applied to single-pipeline at the uniform velocity to be measured, for having the dual circuit design of oil-feed and oil return and equipment that flow velocity changes constantly, this class of diesel motor is difficult to measure.In addition, the sensor of oval gear flowmeter has certain reasonable tolerance in process of manufacture, if two larger flow sensors of tolerance factor gap are arranged on the oil-feed of same vehicle and return line and certainly will will affect the overall calculation precision of flowmeter simultaneously.
At present, in market, other have also problem of ubiquity function singleness all of the various device of flow metering function and utensil, only can measure the flow of flow velocity equilibrium, can not measure accurately speed change flow, more cannot measure and computing two different speed change flows simultaneously, therefore be difficult to carry out in diesel motor field the application of oil consumption measure monitor.And in actual applications, even when diesel motor is carried out to single tube flow metering, also exist manually deliberately flow sensor to shield, do not start or the manual operation such as dismounting, make flow sensor ineffective, even move under the state that diesel car can also cannot be monitored at installation flowmeter, cannot measure the true oil consumption of diesel motor, have a strong impact on oily supervision for vehicle, produce huge administrative vulnerability.
Summary of the invention
The object of this invention is to provide that a kind of volume is little, simple installation, accurate measurement, strong, the convenient diesel motor oil consumption gauge detecting of anti-theft.
The present invention includes power supply in elliptic gear flow sensor I, elliptic gear flow sensor II, Hall rotational speed probe, data line, display and car, shrouding in the middle of being provided with between elliptic gear flow sensor I and elliptic gear flow sensor II, two elliptic gear flow sensors divide be located in the middle of shrouding two sides, between each elliptic gear flow sensor and middle shrouding, by screw, be connected and fixed, form clamping plate type one-piece construction; In middle shrouding, insert double end combined type Hall rotational speed probe is installed, described double end combined type Hall rotational speed probe is connected with display by data line, and display is connected with power supply in car by power lead; The oil inlet pipe of described elliptic gear flow sensor I and diesel motor is connected, and the scavenge pipe of described elliptic gear flow sensor II and diesel motor is connected; In elliptic gear flow sensor I, install normally closed solenoid valve additional, normally closed solenoid valve and double end combined type Hall rotational speed probe shared data line, and connect by data line and display, through display, connect in the lump power supply in car.
Described double end combined type hall probe is comprised of two hall probes and probe socket, probe socket adopts seven needle interface structures, hall probe is three pin configuration, and the positive pole separation of two hall probes, negative pole share, and the residue contact pin of probe socket is connected with normally closed solenoid valve; Probe socket is connected by data line and display.

Principle of work and process, the oil inlet pipe of elliptic gear flow sensor I and diesel motor is connected, and the scavenge pipe of elliptic gear flow sensor II and diesel motor is connected, after vehicle power-on, whole system normally moves, and normally closed solenoid valve is opened simultaneously.After engine start, first diesel oil enter in engine after normally closed solenoid valve flows into elliptic gear flow sensor I, and after diesel motor burning, residue diesel oil returns to fuel tank through elliptic gear flow sensor II again.Four elliptic gears in whole process in two flow sensors rotate simultaneously, send electromagnetic signal simultaneously, by the double end combined type Hall rotational speed probe in middle shrouding, carry out Integral synchronous collection, Hall rotational speed probe is transferred to the CPU in display by collection result by data line, according to the tolerance factor of single flow sensor, carry out computing, and on display, show the operational data with oil mass and two flow sensors, the positive pole of described double end combined type Hall rotational speed probe is separated, negative pole shares, normally closed solenoid valve working power line accesses display in the lump by data line after being connected with the contact pin of probe socket, again by power connection in display and car, the integrated power supply function of solenoid valve.When display is switched on, normally closed solenoid valve, flow sensor are all in running order, and diesel oil can enter engine by elliptic gear flow sensor I.Otherwise any position line departs from, normally closed solenoid valve all will be closed, and diesel oil cannot enter engine by normally closed solenoid valve, elliptic gear flow sensor I, and engine is in dead ship condition, and vehicle now cannot move.
Display part: display is mainly responsible for the working order of data processing and two elliptic gear flow sensors of reflection, carries out calculation process, and result is presented on display screen by built-in CPU according to the program of input before.Display screen shows respectively fuel oil record and the flow sensor rotary speed data of total accumulative total and single class accumulative total and points out in unit exception situation.
Compared with the prior art, beneficial effect of the present invention is:
1, compact to design, be convenient to install, be particularly suitable for the fuel oil record of the diesel motor of oil inlet and oil return dual tube designs;
2, accurate measurement, carries out synchronization monitoring statistics to the entering of diesel motor, scavenge pipe, adopts two close flow sensors of tolerance factor to measure simultaneously, more accurate compared with traditional quadrature instrument metering result;
3, display interface design science, can intuitively understand equipment operation situation, can carry out password setting to display, and operation result needs managerial personnel to input password can to check;
4, solenoid valve has electronic control function, and controllable flow quantity sensor and diesel motor synchronous operation can be stopped the artificial situation that shields or do not start or dismantle flow sensor when Vehicle Driving Cycle.
