Embodiment 2
[0027] Embodiment 2, a method for stabilizing the voltage of the voltage stabilizing system of the high-pressure water jet system mounted on the TBM, comprising the following steps:
[0028] S1: Before starting the high-pressure water jet system, set the target operating pressure of the high-pressure water jet system;
[0029] S2: After starting the system, the high-pressure water jet system operates under the set pressure, water flows from the water tank 1 through the filter 2 and enters the first high-pressure pipeline, and the water in the first high-pressure pipeline enters the storage tank under the action of the high-pressure pump 5 energy device 7;
[0030] S3: During the operation of the high-pressure water jet system, the pressure transmitter 8 will transmit the pressure value of the accumulator to the upper computer 13 in real time, and the upper computer 13 adjusts the pressure value in the accumulator through the pressure stabilizing mechanism to stabilize the pres...

The invention discloses a voltage stabilizing system and a voltage stabilizing method of a high-pressure water jet system mounted on a TBM, which solves the problem of unstable pressure of the high-pressure water jet system in the prior art. The present invention includes a water tank and an accumulator. The water tank is connected to the accumulator through a first high-pressure pipeline. At least one pressure stabilizing mechanism is arranged on the first high-pressure pipeline. A pressure transmitter is arranged on the accumulator. The transmitter is connected with the input end of the upper computer, and the voltage stabilizing mechanism is connected with the output end of the upper computer. The pressure transmitter of the present invention will transmit the pressure value of the accumulator to the host computer in real time, and the host computer will adjust the pressure value in the accumulator through the pressure stabilizing mechanism to stabilize the pressure; that is, by controlling the amount of water entering the accumulator How much, to control the internal pressure of the accumulator, this voltage stabilization method is simple, easy to control, and has a high safety factor.
Description
technical field [0001] The invention relates to the technical field of high-pressure water tunnel excavation, in particular to a voltage stabilizing system and a voltage stabilizing method of a high-pressure water jet system mounted on a TBM. Background technique [0002] High-pressure water jet cutting is a method of pressurizing water to an ultra-high pressure, so that the water obtains pressure energy, and then sprays out from a small nozzle, converting the pressure energy into kinetic energy, thereby forming a high-speed jet. High-pressure water jet cutting is exactly The kinetic energy of this high-speed jet is used to destroy the object and complete the cutting. [0003] High-pressure water jet assisted rock breaking is a form of rock breaking that combines high-pressure water jetting with traditional TBM mechanical rock breaking. Although water jet cutting is relatively mature and widely used, the use of high-pressure water jet for rock cutting during tunnel excavati...
