No-pump high-pressure pulsed water jet generation device

Abstract

The invention discloses a no-pump high-pressure pulsed water jet generation device which comprises a pulsed jet generation component, a power supply (1), a sparking plug (2), an oxygen tank (5), a hydrogen tank (17), a water tank (10) and a centrifugal blower (18), wherein the pulsed jet generation component comprises a power chamber body (3), a first-stage piston (6), a connecting rod (7), a spring, a base (9), a second-stage piston (15), a jet chamber body (11), a valve core (14) and a sealing ring (13); the first-stage piston (6) is positioned in the power chamber body (3), and the second-stage piston (15) is positioned in the jet chamber body (11); the first-stage piston (6) is connected with the second-stage piston (15) through the connecting rod (7) passing through the base (9); the central axes of the power chamber body (3), the jet chamber body (11) and the base (9) are on the same straight line. According to the no-pump high-pressure pulsed water jet generation device, the pistons are pushed by energy generated by explosion of mixed gas of oxygen and hydrogen to move so as to squeeze out water in a chamber, the reciprocating motion of the pistons generate pulsed jet, and therefore the effective pulsed water jet can be generated without a high-pressure pump. The device has the advantages of being simple in structure, low in cost and convenient to use.

Description

technical field [0001] The invention relates to the field of water jet technology, in particular to a pumpless high-pressure pulse water jet generating device. Background technique [0002] Water jet technology, a new technology involving multiple disciplines, has developed rapidly in recent decades due to its increasingly wide application. In order to improve the strike force and working efficiency of water jet, pulse water jet came into being. The pulsed water jet is a discontinuous jet. The separated water clusters ejected by the emitter periodically act on the target, generating a stagnation pressure far greater than that of the continuous jet at the same pressure, commonly known as "water hammer", so that the When the pump pressure is increased, it will cause huge damage to the target. [0003] Pulsed water jets can be divided into self-excited and other-excited according to the generation method. The self-excited type uses the principles of elastohydrodynamics and h...

AI Technical Summary

Problems solved by technology

For high-pressure jets with large flow rates, the cost of high-pressure pumps required is high, heavy, inconvenient to move, and high in maintenance costs

[0005] At present, there is no device or method that has high energy utilization rate, low maintenance cost, and does not need to provide a high-pressure pump to generate an effective pulsed jet.
