Abstract
The utility model discloses an electric fuel oil pump heat test device comprising a fuel oil tank, a constant-temperature box and a test box. The oil supply end of the fuel oil tank is connected with the inlet of the constant-temperature box. An oil inlet pipe is arranged between the outlet of the constant-temperature box and the inlet of the test box. The outlet of the test box is connected with an oil outlet pipeline. A tested electric fuel oil pump is disposed in the test box. The oil inlet pipe is provided with a first thermometer. The oil outlet pipeline is provided with a second thermometer and a flow meter. By adopting the structure and using a well-known heat calculation formula, the exact heat generated by the electric fuel pump in unit time can be effectively detected so that people can control the heat generated by the electric fuel pump within a proper range more precisely and more effectively.
Description
Technical field
The utility model relates to a kind of proving installation, is specifically related to a kind of for testing the proving installation of electric fuel punp thermal value.
Background technology
The Main Function of electric fuel punp is that the fuel oil in fuel tank is sucked to its inside and flows to fuel oil supply system with certain pressure, during due to electric fuel oil pump work, can produce heat, and in the time that the heat producing is excessive, not only can cause damage to electric fuel punp itself, but also easily make the fuel gasification in fuel tank, even blast, therefore in actual applications, people must be controlled at the thermal value of electric fuel punp in suitable scope, but at present, but lack in the prior art the proving installation that is applied to mutually test electric fuel punp thermal value.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of proving installation that can be used for detecting electric fuel punp thermal value.
For achieving the above object, the utility model provides a kind of electric fuel punp test of heating value device, comprise fuel tank, constant temperature oven and test box, the fuel feeding end of described fuel tank and the import of constant temperature oven are joined, between the outlet of described constant temperature oven and the import of test box, be provided with inflow pipeline, in the outlet of described test box, be connected with flowline, tested electric fuel punp is placed in test box, described inflow pipeline is provided with the first thermometer, and described flowline is provided with the second thermometer and flowmeter.
The beneficial effects of the utility model are: adopt said structure, when detection, fuel oil in fuel tank is first input in constant temperature oven, make the initial temperature of described fuel oil be set to a constant numerical value, then enter test box through inflow pipeline, now measured the initial temperature of fuel oil by the first thermometer, enter into fuel oil in test box absorbed by tested electric fuel punp and be heated to uniform temperature with the work of electric fuel punp after exported by flowline, now the second described thermometer can be measured the temperature after fuel oil is heated, described flowmeter can be measured the mass rate of fuel oil, therefore can draw Q=△ t × m × C=△ (T2-T1) × (qmt) × C in conjunction with known heat Calculation formula, wherein T2 represents the temperature that the second thermometer is measured, T1 represents the temperature that the first thermometer is measured, qm represents the mass rate that flowmeter is measured, t represents the test duration, C represents the specific heat capacity of fuel oil, is a definite value.In sum, adopt above-mentioned proving installation and can effectively detect the accurate thermal value in the electric fuel punp unit interval according to above-mentioned computing formula, more accurately and efficiently the thermal value of electric fuel punp is controlled in suitable scope thereby be convenient to people.
The utility model can further be set to be connected with oil returning tube between described flowline and fuel tank.
Adopt further and arrange, set up oil returning tube, can make the fuel oil energy after test return in fuel tank, avoid causing fuel oil waste.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Provide as shown in Figure 1 a kind of electric fuel punp test of heating value device, comprise fuel tank 1, constant temperature oven 2 and test box 3, the fuel feeding end of described fuel tank 1 and the import of constant temperature oven 2 are joined, between the import of the outlet of described constant temperature oven 2 and test box 3, be provided with inflow pipeline 4, in the outlet of described test box 3, be connected with flowline 5, tested electric fuel punp is placed in test box 3, described inflow pipeline 4 is provided with the first thermometer 6, described flowline 5 is provided with the second thermometer 7 and flowmeter 8, between described flowline 5 and fuel tank 1, be connected with oil returning tube 9.
Adopt said structure, when detection, fuel oil in fuel tank 1 is first input in constant temperature oven 2, make the initial temperature of described fuel oil be set to a constant numerical value, then enter test box 3 through inflow pipeline 4, now measured the initial temperature of fuel oil by the first thermometer 6, enter into fuel oil in test box 3 absorbed by tested electric fuel punp and be heated to uniform temperature with the work of electric fuel punp after exported by flowline 5, now the second described thermometer 7 can be measured the temperature after fuel oil is heated, described flowmeter 8 can be measured the mass rate of fuel oil, therefore can draw Q=△ t × m × C=△ (T2-T1) × (qmt) × C in conjunction with known heat Calculation formula, wherein T2 represents the measured temperature of the second thermometer 7, T1 represents the measured temperature of the first thermometer 6, qm represents the mass rate that flowmeter 8 is measured, t represents the test duration, C represents the specific heat capacity of fuel oil, is a definite value.In sum, adopt above-mentioned proving installation and can effectively detect the accurate thermal value in the electric fuel punp unit interval according to above-mentioned computing formula, more accurately and efficiently the thermal value of electric fuel punp is controlled in suitable scope thereby be convenient to people.
