Abstract
The utility model relates to an injector checking device, in particular to a combined injector checking device. According to the technical scheme, the combined injector checking device mainly comprises an injector joint, a solenoid valve, an oil return pipe, an oil tank, an oil inlet pipe, a high-pressure oil pump, a high-pressure oil pipe, a pressure meter, an oil outlet pipe, a control line and a control power supply. An outlet of the injector joint is connected with the oil tank through the oil outlet pipe, the oil tank is connected with the high-pressure oil pump through the oil inlet pipe, the high-pressure oil pump is connected with an inlet of the injector joint, the oil return pipe is arranged between the oil tank and the high-pressure oil pipe, the solenoid valve and the pressure meter are arranged on the oil return pipe, and the injector joint is connected with the control power supply through the control line. The combined injector checking device has the advantages that an injection nozzle, the solenoid valve and the joint can be checked by modifying the device, maintenance and replacement costs of the device are lowered, production cost is saved, and work efficiency is improved.
Description
Technical field
The utility model relates to a kind of oil sprayer checking apparatus, particularly a kind of unit injector checking apparatus.
Background technique
Sweden's EFI Volvo generator set has been promoted for many years in the oil field, owing to the each side reason, cause the rate of fault of generator set very high, be mainly manifested in the fracture of oil nozzle premature wear or contained spring, oil nozzle damages the rear domestic this oil sprayer checking apparatus that also do not have, Volvo producer does not provide the oil sprayer Laboratory Furniture yet, can only change injector assembly under the present condition, the price of the injector assembly of one cover TAD1641GE generator set is 1.2 ten thousand yuan, the TAD1641GE generator set is six cover injector assemblies, and the price of changing whole injector assemblies is 7.2 ten thousand yuan.Injector-Fault generally all is oil nozzle wearing and tearing and spring wearing and tearing or fracture, if pump injector assembly is only changed oil nozzle and nozzle spring only needs about 1,000 yuan, but because the inspection of common injector testing equipment does not measure the injection pressure of oil nozzle, so pump nozzle injection pressure cannot be adjusted after having changed oil nozzle and spring, also just can not use, cause very large waste and the raising of maintenance expenses.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of unit injector checking apparatus is provided, and has saved cost of production, has improved working efficiency.
Its technological scheme is: mainly be comprised of fuel injector connector, solenoid valve, return tube, fuel tank, oil inlet pipe, high pressure oil pump, high-pressure oil pipe, pressure gauge, oil outlet tube, guide line, control power supply, the outlet of fuel injector connector connects fuel tank by oil outlet tube, be connected by oil inlet pipe between fuel tank and the high pressure oil pump, high pressure oil pump connects the entrance of fuel injector connector by high-pressure oil pipe, be provided with return tube between described fuel tank and the high-pressure oil pipe, described return tube is provided with solenoid valve and pressure gauge, and fuel injector connector connects the control power supply by guide line.
The beneficial effects of the utility model are: put the verification that can realize oil nozzle and solenoid valve and joint by repacking, reduced the expense that device maintenance is changed, saved cost of production, improved working efficiency.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Among the upper figure: fuel injector connector 1, solenoid valve 2, return tube 3, fuel tank 4, oil inlet pipe 5, high pressure oil pump 6, high-pressure oil pipe 7, pressure gauge 8, oil outlet tube 9, guide line 10, control power supply 11.
Embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model mainly is by fuel injector connector 1, solenoid valve 2, return tube 3, fuel tank 4, oil inlet pipe 5, high pressure oil pump 6, high-pressure oil pipe 7, pressure gauge 8, oil outlet tube 9, guide line 10, control power supply 11 forms, the outlet of fuel injector connector 1 connects fuel tank 4 by oil outlet tube 9, be connected by oil inlet pipe 5 between fuel tank 4 and the high pressure oil pump 6, high pressure oil pump 6 connects the entrance of fuel injector connector 1 by high-pressure oil pipe 7, be provided with return tube 3 between described fuel tank 4 and the high-pressure oil pipe 7, described return tube 3 is provided with solenoid valve 2 and pressure gauge 8, and fuel injector connector 1 connects control power supply 11 by guide line 10.
Whole checking procedure of the present utility model is: the oil nozzle that needs verification and solenoid valve and joint are taken off from injector assembly, be connected to below the fuel injector connector 1, oil nozzle, solenoid valve, joint and fuel injector connector 1 form an integral body, start high pressure oil pump 6 in the removal system behind the air, fuel oil in the high pressure oil pump 6 is given fuel injector connector 1 fuel feeding by high-pressure oil pipe 7, when oil outlet tube 9 has oil return, open control power supply 11 by guide line 10 solenoid valve to oil sprayer, solenoid valve is closed, cut off the oil return of oil sprayer, fuel injector connector 1
Just directly give the oil nozzle fuel feeding, after high pressure oil pump 6 charge oil pressures reach certain numerical value, high pressure oil is just opened the needle-valve body of oil nozzle, realize oil spout, this moment, the numerical value of pressure gauge 8 was the injection pressure of oil nozzle, when force value and authorized pressure are not inconsistent, can adjust pressure by the compression spring above the increase and decrease oil nozzle, until meet, be the injection pressure of capable of regulating oil nozzle by this device, can see again the atomization quality of oil nozzle.After oil nozzle has been proofreaied and correct, open solenoid valve 2, intrasystem high pressure fuel is back to fuel tank 4, takes off oil nozzle and installs on the injector assembly, has finished whole checking procedure.
