Description
An electromagnetic alternating pulsed abrasive water-jet generator LU101303 Technical Field The invention relates to the design of water-jet mechanical equipment, in particular to an electromagnetic alternating pulsed abrasive water-jet generator.
Background Water jet refers to the high-speed water beam of different shapes outflowing from a nozzle, and the flow velocity of the jet depends on the pressure drop at the nozzle outlet.
The water jet is the simplest form of energy transformation and application.
Usually, a power-driven pump draws a certain amount of water and discharges it to a high-pressure pipeline, allowing the water to arrive at the nozzle with a certain energy.
The bore diameter of the nozzle is much smaller than the diameter of the high-pressure pipeline; therefore, the water arriving at the nozzle must be accelerated so as to flow out.
Thus, the accelerated and condensed water flowing out of the nozzle transforms into a water jet.
However, the current electromagnetic alternating pulsed abrasive water-jet generator cannot adopt the electromagnetic-driven intermediate accelerating component to drive the mixture of water and low-pressure abrasive to form pulsed high-pressure jet, and thus, high-pressure containers are required to be used as storage tanks for abrasive.
It is inevitable to use high-pressure water and abrasive to conduct mixing in the mixing chamber under high pressure for outputting high-pressure jet.
Moreover, pump stopping for sand filling cannot be avoided, which largely lowers the work time and efficiency of abrasive jet.
Some electromagnetic alternating pulsed abrasive water-jet generator can neither limit the extreme position of the elastic sleeve and the position of elastic sleeve and impact pressing sleeve, nor effectively prevent the failure of elastic sleeve and impact pressing sleeve due to the direct collision between them; some electromagnetic alternating pulsed abrasive water-jet generators cannot ensure that the mixture of abrasive and water under high-pressure state gets out of the nozzles successfully; some electromagnetic alternating pulsed abrasive water-jet generators cannot alternately | accelerate the intermediate accelerating component to accelerate the mixture of abrasive and water in the electromagnetic pulsed abrasive transmitting channels under low-pressure state at two sides of the intermediate accelerating component to high-pressure state, some electromagnetic alternating pulsed abrasive water-jet generators cannot input the abrasive on theinner wall of the low-pressure abrasive cylinder to the middle of the low-pressure abradiyd01303 cylinder and accelerate to make the abrasive fluidized and easily transmitted into the vertical pipe; some electromagnetic alternating pulsed abrasive water-jet generators cannot increase the degree of fluidization for the abrasive in the low-pressure abrasive cylinder and realize fast input into the vertical pipe of the abrasive; some electromagnetic alternating pulsed abrasive water-jet generators cannot effectively prevent the side of impact pressing sleeve from blocking the lower outlet of the vertical pipe due to over-speed of the intermediate accelerating component, leading to the failure of the abrasive to enter the electromagnetic pulsed abrasive transmitting channel due to blocking, which cannot meet the actual needs.
Therefore, it is necessary to provide an electromagnetic alternating pulsed abrasive water-jet generator with a simple structure that is safe, high-efficient and easy to operate.
Summary of the Invention The invention is to overcome the defects of the prior art and provide an electromagnetic alternating pulsed abrasive water-jet generator with a simple structure that is safe, high-efficient and easy to operate.
In order to solve the technical problems, the technical scheme of the invention is given as follows: an electromagnetic alternating pulsed abrasive water-jet generator comprises a console and a pump station as well as an electromagnetic pulsed abrasive transmitting channel and a low-pressure abrasive cylinder; the electromagnetic pulsed abrasive transmitting channel is installed with an extreme-position hard spring, an elastic sleeve, a cushion soft spring and an impact pressing sleeve from outside to inside; the extreme-position hard spring, the elastic sleeve, the cushion soft spring and the impact pressing sleeve are symmetrically installed in the electromagnetic pulsed abrasive transmitting channel; the extreme-position hard spring, the elastic sleeve, the cushion soft spring and the impact pressing sleeve are located at the end of the electromagnetic pulsed abrasive transmitting channel; a forward-direction electrified coil is installed at the left end of the electromagnetic pulsed abrasive transmitting channel; a | reverse-direction electrified coil is installed at the right end of the electromagnetic pulsed | abrasive transmitting channel; the forward-direction electrified coil and the reverse-direction electrified coil are both located at the inner side of two cushion soft springs; an intermediate accelerating component is installed in the electromagnetic pulsed abrasive transmitting channel; a U-shape pipe is installed at the outer side of the low-pressure abrasive cylinder; vertical sidepipes are installed at two sides of the U-shape pipe and fluidized uniformly-distribukél{ 01303 fan-shaped nozzles are installed on the inner side of the vertical side pipes; the diameter of the fluidized uniformly-distributed fan-shaped nozzles decreases from upper to lower; a vertical pipe is installed at the lower end of the low-pressure abrasive cylinder; the port at the bottom of the vertical pipe connects with the electromagnetic pulsed abrasive transmitting channel; the vertical pipe is located between the elastic sleeve and the impact pressing sleeve; the pressed limit end face at the right side of the cushion soft spring is located at the outer side of the inner side wall of the vertical pipe.
A current direction controller is mounted at the upper end of the console, the conductors on the forward-direction electrified coil and the reverse-direction electrified coil are respectively connected to the current direction controller, and nozzles are installed at two ends of the electromagnetic pulsed abrasive transmitting channel.
A concentration regulator is installed on the vertical pipe, a concentration regulating pipe is mounted at the right end of the concentration regulator, the right end of the regulating concentration pipe is connected to the bottom of the pump station through a one-way valve, a sand-brake valve is installed on the concentration regulator, and a connector is mounted at the upper end of the U-shape pipe.
The low-pressure abrasive cylinder is located at two sides of the pump station, the two sides of the pump station are connected with the connector through a hosepipe, and an end cap is mounted at the upper end of the low-pressure abrasive cylinder.
In practical application, first of all, the operator should fix the pending sample piece on the workpiece desk at two sides of the nozzle, adjust the shooting distance between the pending sample piece and the nozzle, then open the end cap at the upper end of the low-pressure abrasive cylinder, pour the screened abrasive into the low-pressure abrasive cylinder, and close the end cap after the low-pressure abrasive cylinder is full.
Next, the operator should launch the pump station to divide the low-pressure water into two flows. One of the two flows will flow into the U-shape pipe through the connector, where the low-pressure water will flow into low-pressure abrasive cylinder through vertical side pipe and fluidize the abrasive in the low-pressure abrasive cylinder. Because the diameter of the vertical side pipe decreases from upper to lower, the fluidization of the abrasive in the low-pressure abrasive cylinder intensifies from upper to lower, and the abrasive flows into the concentrationregulator through vertical pipe. The other flow of low-pressure water flows into tk 01303 concentration regulator through the regulating concentration pipe, and the position of the sand-brake valve on the concentration regulator is adjusted to mix the low-pressure water and the fluidized abrasive in the concentration regulator into the abrasive mixture with certain concentration.
Besides, the abrasive mixture with certain concentration flows into the electromagnetic pulsed abrasive transmitting channel through vertical pipe until the pipe is full; when the intermediate accelerating component is located in the forward-direction electrified coil, the current direction controller on the console is started to electrify the forward-direction coil, and the intermediate accelerating component under electrified operation will be driven by the electromagnetic force to promote the low-pressure abrasive mixture at the right side of the intermediate accelerating component into the nozzle through impact pressing sleeve and elastic sleeve and get out of the nozzle, forming pulsed jet flow; after the intermediate accelerating component enters into the reverse-direction electrified coil, the current direction controller on the console will electrify the coil, and the intermediate accelerating component under electrified operation will be driven by the electromagnetic force to promote the low-pressure abrasive mixture at the left side of the intermediate accelerating component into the nozzle through impact pressing sleeve and elastic sleeve and get out of the nozzle, forming pulsed jet flow; the current direction controller is repeatedly launched to form alternating pulse output of the abrasive from two ends of the electromagnetic pulsed abrasive transmitting channel, and the pending sample piece is processed.
Finally, the operator should close the pump station, close the sand-brake valve on the concentration regulator to prevent the abrasive from entering into the electromagnetic pulsed abrasive transmitting channel via the vertical pipe, then close the current direction controller on the console, properly clean up the abrasive in the low-pressure abrasive cylinder according to the next operation time, and regularly maintain the equipment to wait for the next process operation.
Compared with the prior art, the beneficial effects of the invention are as follows: the invention adopts the electromagnetic-driven intermediate accelerating component to drive the mixture of water and low-pressure abrasive to form pulsed high-pressure jet, without using high-pressure container as abrasive storage tank and using high-pressure water and abrasive to conduct mixing in the mixing chamber under high pressure for outputting high-pressure jet.
Moreover, pump stopping for sand filling can be effectively avoided, which largely lengthens té 01303 work time and efficiency of abrasive jet.
Through setting extreme-position hard spring, the elastic sleeve, the cushion soft spring and the impact pressing sleeve, both of the extreme position of the elastic sleeve and the position of elastic sleeve and impact pressing sleeve can be 5 limited, direct collision of the impact pressing sleeve and the elastic sleeve to cause damage can be effectively avoided, and the elastic sleeve and impact pressing sleeve can ensure that the mixture of abrasive and water under high-pressure state get out of the nozzles successfully; through setting electromagnetic pulsed abrasive transmitting channel, forward-direction electrified coil, adverse-direction electrified coil and intermediate accelerating component, the intermediate accelerating component can be alternately accelerated to accelerate the mixture of abrasive and water in the electromagnetic pulsed abrasive transmitting channels under low-pressure state at two sides of the intermediate accelerating component to high-pressure state, so as to forms pulse electromagnetic abrasive jet after getting out of the nozzle; through setting U-shape pipe, vertical side pipe and fluidized uniformly-distributed fan-shaped nozzle, the abrasive on the inner wall of the low-pressure abrasive cylinder can be input to the middle of the low-pressure abrasive cylinder, accelerated to the fluidized state and transmitted into the vertical cylinder; through using fluidized uniformly-distributed fan-shaped nozzle with diameter decreasing from upper to lower, the degree of fluidization for the abrasive in the low-pressure abrasive cylinder can be increased from upper to lower and the fast input into the vertical pipe of the abrasive can be realized; through setting the area between the elastic sleeve and impact pressing sleeve with vertical pipe and locating the pressed limit end face at the right side of the cushion soft spring to the outer side on inner wall of the vertical pipe, the intermediate accelerating component causing the side of impact pressing sleeve to block the lower outlet of the vertical pipe due to over-speed, which leads to the failure of the abrasive to enter the electromagnetic pulsed abrasive transmitting channel due to blocking, can be effectively avoided.
In addition, it has a simple structure and is practical, economical and easy to operate.
