Description

technical field [0001] The invention relates to a cylinder pressure stabilization control device and a use method, belonging to the technical field of petroleum seismic exploration equipment. Background technique [0002] At present, the heavy hammer pulse source at home and abroad mainly adopts the structure driven by cylinder compression energy storage, and its principle is as follows: figure 1 As shown. The nitrogen cylinder 2 serves as the inflation pressure source of the cylinder 5; the pre-charge gas pressure in the cylinder is controlled by the pressure reducing valve 3, which can realize different excitation energy requirements; the one-way valve 4 plays a protective role for the pressure reducing valve, and the stop valve 1 Used as an exhaust valve when the system needs to be maintained. [0003] Due to the instability of the compressed state of the gas and the influence of the work done by the gas on the weight on the state of the gas, the pressure of the gas chan...

Problems solved by technology

[0003] Due to the instability of the gas compression state and the influence of the gas on the gas state due to the work done by the gas on the weight, the pressure of the gas after each compression changes greatly, which in turn causes a large difference in the excitation energy each time, and the excitation consistency is poor.
