Arbitrarily can not reduce.But if the high-pressure hydraulic of controlled source can be dropped to the mesohigh used by common engineering machinery
Hydraulic system, its failure calibration can be substantially reduced.
2nd, nominal output is little.In geological prospecting, in order to obtain preferable geologic information, need to improve the volume of controlled source
Power is made, to reach expected exploration effects.
3rd, lock synchronicity low, and discharge difficult.The impact tup of controlled source vibrator is by installed in top at present
The mechanical lock assembly locking in portion and release.When the hook being connected with impact tup rises to top, mechanical lock component controls are stretched
Contracting bar stretches out, and hangs on expansion link, realizes that jump bit head suspension is locked；When release impact tup is needed, mechanical lock section
Expansion link is retracted part the hook being releasably connected with impact tup, so as to discharge impact tup.From the situation of real-world effectiveness
From the point of view of, there is following drawback in this locking mode：Do not discharge in the weight and cylinder of the first-class part of jump bit of hook connection
Gas pressure all born by expansion link, often result in expansion link deformation；To reduce the flexible throw of lever, hook is connect with expansion link
Contacting surface accumulates very little, so linking up with excessive with the easy stress of expansion link contact area and damaging；Expansion link and hook between and
Sliding friction is between expansion link and expansion link sliding channel, frictional force is very big during release.It is additionally, since the deformation of expansion link
And frictional force of expansion link when retracting is excessive, easily causes expansion link by card or the phenomenon do not retracted, i.e.,
Control delayed and poor synchronization.
