Description
Technical field
The utility model belongs to the testing apparatus field, relates to a kind of tractor intake resistance and exhaust back pressure measurement mechanism.
Background technology
The exhaust back pressure of tractor refers to the pressure after the field engine gas outlet, and exhaust back pressure has material impact to dynamic property, economy and the emission behavior of engine.Will cause the motor fuel burning efficiency to descend if back pressure increases, dynamic property descends, and emission effect is also relatively poor.Therefore, the exhaust back pressure of test tractor has great importance to understanding engine characteristics.
Intake resistance refers to the resistance that air intake duct, air filter and the middle engine aspirating system assemblies such as connecting pipe cause engine charge, if in gas handling system, resistance to flow is large, can make motor fuel can not get using perfect combustion, its result will cause the fuel economy variation, the usability problems such as excessive and power reduction of discharging fume.The resistance of gas handling system depends on many variablees, these variablees comprise the shape of pipeline, the smoothness of conduit, the type of flexible joint, the size of pipe, the structure of air inlet cap, the type of bend pipe etc., the unique method of accurately determining SR is by test, as long as the whole system of assembling just should check the resistance of gas handling system.
At present, tractor intake and exhaust pressure-measuring instrument is all independent measurement basically, and due to excessive discharge temperature, existing measuring instrument is difficult to directly measure.
The utility model content
The purpose of this utility model be to provide a kind of simple in structure, esy to use, safe and reliable, tractor intake resistance and exhaust back pressure measurement mechanism.
The utility model can achieve the above object by the following technical programs: tractor intake resistance and exhaust back pressure measurement mechanism comprise: digital instrument, power switch, exhaust back pressure sensor, valve piece, heat radiation cooling system, support, castor, cabinet, high-temperature metal flexible pipe, intake resistance pressure transducer, jointing; Digital instrument and power switch are fixed on the panel of cabinet, and cabinet is placed on castor; Heat radiation cooling system is rack-mount, the high-temperature metal flexible pipe is fixed on the air intake opening of heat radiation cooling system, the valve piece is fixed on the gas outlet of heat radiation cooling system, exhaust back pressure sensor is connected on the valve piece, and the intake resistance pressure transducer is connected with digital instrument by shielding line with exhaust back pressure sensor.
The utility model can reach following beneficial effect after adopting technique scheme: when this device has been realized tractor intake resistance and exhaust back pressure, measurement and data read analysis automatically.Because delivery temperature can reach 600-800 ℃ sometimes, existing high-temperature-resistance pressure sensor is difficult to reach the direct measurement of high-temperature like this, and expensive fragile.This device adopts the pressure transducer of standard temperature scope, and use cost is low, the life-span is long.And be furnished with Moving caster, conveniently be applied to various environment and operating mode.Band with 232 serial communication functions, can be connected in various control system and software simultaneously, facilitates the user to carry out automated analysis and the processing of data.
Description of drawings
Accompanying drawing 1 is the utility model tractor intake and exhaust pressure tester johning knot composition.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done with further description: tractor intake resistance and exhaust back pressure measurement mechanism comprise: digital instrument 1, power switch 2, exhaust back pressure sensor 3, valve piece 4, heat radiation cooling system 5, support 6, castor 7, cabinet 8, high-temperature metal flexible pipe 9, intake resistance pressure transducer 11, jointing 12; Digital instrument 1 and power switch 2 are fixed on the panel of cabinet 8, and cabinet 8 is placed on castor 7; Heat radiation cooling system 5 is arranged on support 6, and high-temperature metal flexible pipe 9 is fixed on the air intake opening of heat radiation cooling system 5, and valve piece 4 is fixed on the gas outlet of heat radiation cooling system 5, and exhaust back pressure sensor 3 is connected on valve piece 4, guarantees to connect without gas leakage.Intake resistance pressure transducer 11 is connected with digital instrument 1 by shielding line with exhaust back pressure pressure transducer 3.
Gas during measurement in tractor gas outlet 13 imports emission gases in heat radiation cooling system 5 through high-temperature metal flexible pipe 9 by jointing 12, high-temperature gas is obtained cooling, the data of then measuring through exhaust back pressure sensor 3 by valve piece 4 are presented on digital instrument 1.Intake resistance is directly connected on tractor draft tube 10 by intake resistance pressure transducer 11, and measured data are presented on digital instrument 1.
