Problems solved by technology

However, the volume of the existing direct-drive three-plunger high-pressure water jet generating device is relatively small, and the plunger rod is very thin (8mm in diameter) and the stroke is very short (40mm). The number of reciprocating movements of the plunger rod must reach 750 times per minute. Therefore, the direct-drive three-plunger high-pressure water jet generating device has high requirements on the hardness and wear resistance of the plunger rod and the material of the high-pressure sealing ring on the plunger rod. , it is difficult to manufacture, and the cost of equipment use and maintenance is relatively high

Abstract

The invention discloses a water jet cutting machine and a jet generation device thereof; the jet generation device comprises a frame, a driving device arranged on the frame, an acting wheel which is arranged on the frame and is rotated under the driving of the driving device, and a pressurization component, wherein the pressurization component comprises a rocker arm, a connecting rod, a push rod and a pressurization part; the rocker arm is arranged on the acting wheel and is rotated with the acting wheel, and the rocker arm drives the push rod to act through the connecting rod, the push rod is connected with a plunger rod of the pressurization part so as to drive the plunger rod to move; the pressurization part is provided with an output port for outputting the jet. The water jet cutting machine and the jet generation device thereof have larger flow and higher pressure, and meanwhile can obviously save energy.

Description

technical field [0001] The invention relates to a water cutting machine and a jet flow generating device thereof, in particular to an ultra-large flow and ultra-high pressure water cutting machine and a jet flow generating device thereof. Background technique [0002] Existing water cutting machines are all equipped with jet generating devices, and the existing ultra-high pressure water jet generating devices are mainly divided into two plunger high pressure water jet generating devices and three plunger high pressure water jet generating devices. [0003] Two-plunger high-pressure water jet generating device such as Figure 7A As shown, its working principle is to use the hydraulic system to push two plunger rods to make linear reciprocating motions in two hydraulic cylinders, compress the water and shoot it through a nozzle with a diameter of only 0.22-0.35mm, thereby generating a high-speed motion. water jet. [0004] The performance indicators of the two-plunger high-pr...
