The invention discloses pressure-infiltration equipment, a pressure-infiltration system and a pressure-infiltration method for oil way and gas way leaking stoppage. The pressure-infiltration equipment comprises a cylinder body, the interior of the cylinder body divided by a leather bag layer into a first cavity and a second cavity, the first cavity is communicated with a first connector used for guiding in / guiding out leaking stoppage media, and the second cavity is communicated with a second connector used for guiding in hydraulic oil so as to apply pressure to the leaking stoppage media in the first cavity through the leather bag layer. By means of the pressure-infiltration equipment, the pressure-infiltration system and the pressure-infiltration method, direct pressure supply to traditional leaking stoppage media through a manual pump is avoided, the hydraulic oil is adopted for indirect pressure supply, curing failures, caused by heat transferring and temperature rise in the pressurization process, of the leaking stoppage media is avoided, curing failures, caused by oxygen deficit, during direct pressure supply of the leaking stoppage media are effectively avoided, the fault probability of pressurization equipment is greatly reduced, the working reliability of the pressure-infiltration system is improved, and the maintaining cost of the pressure-infiltration system is effectively reduced.
Description
technical field [0001] The invention relates to the field of leak plugging equipment, in particular to a pressure-seepage device for leak plugging of an oil channel and an air channel. Background technique [0002] At present, the technical procedure for plugging the oil passage and air passage in the aero-engine casing is briefly as follows: 1. Use pressure seepage equipment to press the plugging medium into the oil passage and air passage in the casing, and maintain the pressure (up to 18MPa) to make the medium penetrate into the oil passage 2. Flush the excess plugging medium in the oil passage and air passage; 3. Heat to solidify the plugging medium in the crack and gap to complete the plugging of the casing oil passage and air passage. The research point of this application lies in the first step, that is, under the premise of ensuring the pressure, the plugging medium is pressure-infiltrated into the crack gap in the oil channel and air channel of the casing.
