Technical field
The present invention relates to the safety tests of marine diesel component, and in particular to a kind of gas fuel injection valves it is multi-functional
Detecting data belongs to Diesel Engine Technique Field.
Technical background
Gas fuel injection valves (Gas Admission Valve, abbreviation GAV, similarly hereinafter) are dual fuel engine sprays peculiar to vessel
The important component of system is penetrated, the function of the part is that the gaseous fuel of timely and appropriate discovery is sprayed inlet casing.
In host actual moving process, in order to ensure to spray in reasonable time, it is desirable that under the action of excitation, valve rod
It can respond within a certain period of time；In order to ensure to spray the fuel of appropriate amount, valve rod is needed to run scheduled displacement；Piston to
Some time point of upper operation start spray fuel, if other times spray, may cause low efficiency of combustion, deterioration of emission, after
Combustion is serious to wait harmful effects, so, in the GAV down periods, the sealing performance of sealing surface plays an important role.It is assembled in host
When, if directly assembling GAV not after testing on host, carry out GAV failures once occur during test run, then need to shut down, carry out
Dismounting, replacement, repair of GAV etc. delay the process of entire production test run, so as to cause the upper of time cost and cost of labor
It rises.
More than reason is based on, needs a kind of equipment that can be detected before GAV installations, the installation for component of fixing a breakdown；
In addition, main engine plants often produce more than one host, so the equipment is also required to that a variety of GAV can be detected.
