Abstract
The invention relates to the technical field of testing devices and particularly relates to a device for testing tightness of combustors of a diesel engine. The device comprises a duct, a wind pressure pipe connector, an explosion reducing valve connector, a ball valve, an explosion reducing valve and a mechanical pressure gauge, one end of the duct is connected with the wind pressure pipe connector, the other end of the duct is connected with the explosion reducing valve connector, the ball valve is arranged at the center of the duct, the explosion reducing valve connector is fixedly connected with the explosion reducing valve, and the mechanical pressure gauge is arranged on the explosion reducing valve connector. The device for testing tightness of the combustors of the diesel engine is simple, compact and reasonable in structure, convenient and fast to assemble, reliable in connection, good in economical efficiency, easy to use and popularize and capable of fast judging tightness of the combustors of cylinders of the diesel engine, saving a large quantity of manpower and material resources due to the fact that a power unit is not required to be dismounted, simultaneously reducing dismounting times of the power unit, reducing fault hidden dangers of the power unit and improving reliability of products.
Description
Technical field
The present invention relates to a kind of technical field of proving installation, especially a kind of burning chamber of diesel engine tightness measuring device.
Background technology
The HXN5 locomotive is equipped with the excessive pressure of crankcase protective device; the crankcase pressure value exceeds specialized range locomotive meeting auto stop; and the sealing of firing chamber determines to scurry into the gas quantity of crankcase; after power packages installs now; can't check the mated condition of piston ring and cylinder jacket; can't judge the sealing effectiveness of power packages firing chamber; reexamine piston ring and cylinder jacket state after power packages can only being split out; workload is very large; and being dismounted for multiple times power packages; may stay the power packages potential faults, cause more large economy loss.
Summary of the invention
Existing burning chamber of diesel engine performing leak test workload is large, test bothers and make easily the power foot stay the deficiency of potential faults in order to overcome, and the invention provides a kind of burning chamber of diesel engine tightness measuring device.
The technical solution adopted for the present invention to solve the technical problems is: a kind of burning chamber of diesel engine tightness measuring device, comprise conduit, wind-pressure tube joint, subtract quick-fried valve union, ball valve, subtract quick-fried valve and mechanical pressure gauge, conduit one end is connected with the wind-pressure tube joint, the other end with subtract quick-fried valve union and be connected, conduit central authorities are provided with ball valve, subtract quick-fried valve union and be fixedly connected with subtracting quick-fried valve, subtract quick-fried valve union and be provided with mechanical pressure gauge.
The invention has the beneficial effects as follows, this burning chamber of diesel engine tightness measuring device is simple in structure, compact and rationally, easy to assembly quick, connection is reliable, can judge fast each cylinder combustion chamber sealing of diesel engine, do not need the dismounting power packages, can save a large amount of manpower and materials, good economy is arranged, reduce simultaneously the dismounting number of times of power packages, can reduce the hidden danger that the power packages fault occurs, improve the reliability of product, be easy to use and promote.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention.
1. conduits among the figure, 2. the wind-pressure tube joint 3. subtracts quick-fried valve union, and 4. ball valve 5. subtracts quick-fried valve, 6. mechanical pressure gauge.
Embodiment
Structural representation of the present invention such as Fig. 1, a kind of burning chamber of diesel engine tightness measuring device, comprise conduit 1, wind-pressure tube joint 2, subtract quick-fried valve union 3, ball valve 4, subtract quick-fried valve 5 and mechanical pressure gauge 6, conduit 1 one ends are connected with wind-pressure tube joint 2, the other end with subtract quick-fried valve union 3 and be connected, conduit 1 central authorities are provided with ball valve 4, subtract quick-fried valve union 3 and are fixedly connected with subtracting quick-fried valve 5, subtract quick-fried valve union 3 and are provided with mechanical pressure gauge 6.
During use, each cylinder power packages is coiled successively to bottom dead center position, this proving installation is subtracted quick-fried valve union 3 and subtracts quick-fried valve 5 and be connected, by this device 0.5MPa pressurized air is pumped in the firing chamber, close the valve that subtracts quick-fried valve 5, record pressure drops to time of 0.1MPa from 0.5MPa, judges thus the sealing effectiveness of power packages firing chamber.This burning chamber of diesel engine tightness measuring device is simple in structure, compact and reasonable, easy to assembly quick, connect reliably, can judge fast each cylinder combustion chamber sealing of diesel engine, do not need the dismounting power packages, can save a large amount of manpower and materials, good economy is arranged, reduce simultaneously the dismounting number of times of power packages, can reduce the hidden danger that the power packages fault occurs, improved the reliability of product, be easy to use and promote.
