Abstract
The utility model relates to a test table for an oil injector. The utility model can be widely suitable for testing the working performance of oil injectors of current various home-made and import internal combustion engine types of diesel engine series. The test table is mainly composed of an oil fuel supplying system, a hydraulic clamping system, an electric appliance control system, etc. The utility model is characterized in that the flow pulsation rate of automatically supplying to a measured oil injector is small, potential energy of pressure is high and stable, and the temperature of the oil fuel for testing rises little. The systems are mutually coordinated, a machine, liquid, electricity and an instrument are integrated into one body, and the utility model has the advantages of perfect design, advanced technology, stable and reliable performance, convenient operation, high efficiency, low noise, etc.
Description
The utility model relates to diesel engine of diesel locomotive parts detection technique.
Injector testing equipment is one of indispensable engineering equipment of railway systems.This test stand can carry out following test: 1, spray the cracking pressure test; 2, jet performance test (atomization test); 3, tight performance test.
One of key factor that influences the injector testing equipment test result is a fuel supply system.At the injector testing equipment that China uses now, its fuel supply system adopts usually: several modes such as high pressure oil pump fuel feeding, monomer-type Injection Pump fuel feeding, modular fuel injector oil pump feed.The fuel oil of these fuel system outputs all can not satisfy test specification fully from aspects such as flow pulsation, pressure surge, oil temperature, noise, efficient.
The purpose of this utility model has provided a kind of novel injector testing equipment, it has adopted fuel liquid supercharging and automatic replenishment apparatus system, hydraulic lock system, electrical apparatus control system, can reach high-quality experimental performance index to accomplish tested oil sprayer.
Injector testing equipment of the present utility model mainly by supplying fuel, hydraulic pressure be installed, system such as electrical equipment control forms.Metal stand 1 bottom is equipped with hydraulic station 2, on the hydraulic station side fuel pressurization device and automatic oiling device 3 is arranged.Stand middle part fuel oil fuel tank 4 links to each other with fog discharge device 5, sprays fast modulating valve 6, Decompression valves 7 is installed on the test table top, above-mentioned parts composition fuel supply system.Oil pooling cylinder 9 be located at the mechanism 10 that is installed below, form the hydraulic lock system.Digital indicator 8 and operation control panel 11 are located at test stand top respectively, form electrical apparatus control system.The operation control panel button, fuel oil injects the fuel pressurization device by pipeline and valve, provides high pressure fuel by one-way valve to tested oil sprayer, carries out various performance tests.
The utility model has adopted the unique design of hydraulic intensifier and automatic oiling device, can offer automatically that tested oil sprayer flow pulsation is little, pressure potential is high, steady, little test fuel oil heats up, make it have characteristics such as noise is low, efficient is high, the experimental performance index is accurate, reliable, have the application value of wide model.
Accompanying drawing 1: injector testing equipment structural representation.
Accompanying drawing 2: injector testing equipment system works schematic representation.
Embodiment:
In conjunction with the accompanying drawings 2 the explanation test stands working procedure, on operation control panel, press 12 work of start button DT3 (energising) oil pump, hydraulic oil flows into the rodless cavity of oil cylinder 15 through selector valve 13, clamp tested oil sprayer 16, start button DT2, hydraulic oil is through selector valve 21, flow into the rod chamber of pressurized machine 19, the piston left lateral, produce negative pressure in the fuel chamber, this moment, hydraulic oil entered in the rod chamber of automatic notes oil burning installation 18 descent of piston simultaneously, open unidirectional element, fuel oil injects in the pressurized machine fuel chamber smoothly.Start button DT1, hydraulic oil enters in the pressurized machine rodless cavity through selector valve 21, series flow control valve 20, this moment rod chamber and the rod chamber and fuel tank connection of notes oil burning installation automatically, fuel oil stops oiling automatically.Fuel oil increases with the pressure that moves to right of piston in the pressurized machine fuel chamber, provides high pressure fuel by one-way valve 14 to tested oil sprayer.Relief valve 22 has the function of adjusting high pressure fuel pressure, gathers pressure information by sensor 17, converts electrical signal to, is shown by fluorescent character display tube.Series flow control valve can accurately be regulated the oil spout frequency, its scope 8-120 time/minute, simultaneously by sensor acquisition information, numeral shows, unidirectional element effect in the series flow control valve is when the pressurized cylinder left lateral, make back pressure valve for it and use, open, finish the automatic injection of fuel oil with the unidirectional element of guaranteeing to annotate in the oil burning installation.Finish the performance test of oil sprayer.
Claims (3)
1, a kind of novel diesel engine of diesel locomotive injector testing equipment, in establish fuel oil fuel tank, fog discharge device, spray fast modulating valve, the hydraulic pressure clamping mechanism is divided into oil pooling cylinder, operation control panel is housed on the test stand, it is characterized in that in the test stand fuel oil fuel tank fuel oil hydraulic intensifier and automatic oiling device being housed.
2, injector testing equipment according to claim 1 is characterized in that the fuel oil hydraulic intensifier is a dual-active plug sleeve cylinder structure.
