A cooling output port 213 is provided at the top of the cylinder cleaning groove 210, and the cooling output port 213 is communicated with the cooling output groove 215. The coolant transferred to the annular guide groove flows into the cylinder cleaning groove 210 through the cooling input port 212 to cool the piston cylinder 204, and is discharged into the cooling output groove 215 through the cooling output port 213. Two plunger pipes are provided in the piston cylinder 204, and a hollow plunger rod 205 is longitudinally slidably installed in the plunger pipe of the piston cylinder 204. A connecting rod is fixedly installed at the bottom of the hollow plunger rod 205, and the top of the transmission inclined plane rod 207 is an inclined plane. An annular groove is provided on the top of the transmission bevel rod 207, and a plurality of support sliders 206 are slidably installed in the annular groove on the top of the transmission bevel rod 207. The number of the support sliders 206 is the same as that of the hollow plunger rod 205. The support slider 206 is ball-jointedly connected to the connecting rod at the bottom of the hollow plunger rod 205. A transmission rod is fixedly installed at the bottom of the transmission bevel rod 207. The transmission rod at the bottom of the transmission bevel rod 207 is connected to an external transmission system. By starting the external transmission system, the transmission bevel rod 207 is driven to rotate in the supporting outer cylinder body 201. When the transmission bevel rod 207 rotates, the guide blades 208 are driven to rotate together, and the external coolant is input into the supporting outer cylinder body 201 through the injection hole at the bottom of the sealing bottom plate 202 through the rotation of the guide blades 208.When the transmission inclined plane rod 207 rotates, the inclined plane at the top drives the hollow plunger rod 205 to slide back and forth in the piston cylinder 204 to work. During this period, the coolant inside the outer cylinder body 201 is driven by the guide blades 208 to flow through the outer wall of the hollow plunger rod 205 and clean it. Then, it enters the annular guide groove at the bottom of the piston cylinder support block 203 through the guide cone plate 211, and enters the cylinder cleaning groove 210 through the cooling input port 212 to cool the piston cylinder 204. Then, the coolant is discharged into the cooling output groove 215 through the cooling output port 213, and is transmitted to the top of the transmission support rod 214 through the cooling output groove 215 to wait for discharge, completing the cleaning and cooling of the plunger pump.
[0026] like Figures 1 to 9 As shown, a spiral groove is provided at the bottom of the inner wall of the hollow plunger rod 205, a buffer plunger rod 209 is longitudinally slidably installed in the hollow plunger rod 205, the top outer wall of the buffer plunger rod 209 is slidably matched with the inner wall of the hollow plunger rod 205, and a spherical key is fixedly installed on the bottom outer wall of the buffer plunger rod 209, and the spherical key at the bottom of the buffer plunger rod 209 is slidably matched with the spiral groove on the inner wall of the hollow plunger rod 205, which is used to control the buffer plunger rod 209 to make a rotational movement when sliding in the hollow plunger rod 205, so as to facilitate the cleaning of the attachments on the inner wall of the hollow plunger rod 205 and prevent impurities in the conveyed liquid from adhering to the hollow plunger rod. The inner wall of 205 affects the volume inside the hollow plunger rod 205. When the transmission inclined plane rod 207 rotates to drive the hollow plunger rod 205 to slide back and forth in the piston cylinder 204, and the liquid is extracted and pushed out by the piston movement of the hollow plunger rod 205, the buffer plunger rod 209 is affected by the adsorption force and pressure of the liquid, and slides back and forth synchronously in the hollow plunger rod 205, so as to buffer the flow inertia of the liquid, reduce the resistance encountered by the hollow plunger rod 205 when sliding in the piston cylinder 204, reduce the wear between the connecting rod at the bottom of the hollow plunger rod 205 and the supporting slider 206, and improve the service life of the equipment.
[0027] like Figures 1 to 9As shown, a plurality of pairs of flow holes are provided on the top of the supporting outer cylinder body 201, and the flow holes on the top of the supporting outer cylinder body 201 are connected to the flow pipes in the piston cylinder 204. A transmission mechanism 1 is fixedly installed on the top of the supporting outer cylinder body 201, and the transmission mechanism 1 includes a transmission bin 103, and the transmission bin 103 is fixedly installed on the top of the supporting outer cylinder body 201. A plurality of buffer slots 107 are provided in the transmission bin 103, and the position of the buffer slots 107 is opposite to the piston cylinder 204, and covers the top of each pair of flow holes on the top of the supporting outer cylinder body 201. A transmission cover plate 101 is fixedly installed on the top of the transmission bin 103, and a plurality of buffer slots 107 are longitudinally slidably installed in the transmission cover plate 101. Clean the sliding rod 105, a compression spring is fixedly installed between the top of the cleaning sliding rod 105 and the transmission cover plate 101, a disc-shaped filter is provided at the bottom of the cleaning sliding rod 105, and a guardrail is provided on the edge of the filter. The disc-shaped filter at the bottom of the cleaning sliding rod 105 is longitudinally slidably installed in the buffer groove 107, and is located in the lower half of the buffer groove 107. A plurality of pairs of fluid transmission ports 104 are fixedly installed on the transmission chamber 103, and each pair of fluid transmission ports 104 is connected to the buffer groove 107. A one-way transmission valve 106 is fixedly installed in the fluid transmission port 104 for controlling the one-way flow of the liquid. A filter is fixedly installed at the outer end of the fluid transmission port 104. When When the transmission inclined rod 207 drives the hollow plunger rod 205 to perform reciprocating piston movement in the piston cylinder 204, the liquid to be transmitted flows into the buffer groove 107 and the hollow plunger rod 205 through one of the fluid transmission ports 104 connected to the buffer groove 107 for buffering, and is discharged through another fluid transmission port 104 connected to the buffer groove 107 to achieve liquid transmission. During this period, when the liquid flows from the fluid transmission port 104 into the buffer groove 107 and the piston cylinder 204, the flow of the liquid drives the cleaning sliding rod 105 to slide downward in the transmission cover plate 101, so that the disc-shaped filter screen and the circulation at the top of the supporting outer cylinder body 201 are connected. The holes are in contact with each other to filter out impurities in the liquid. When the liquid is discharged from the buffer groove 107 and the piston cylinder 204, the compression spring between the cleaning sliding rod 105 and the transmission cover plate 101 drives the cleaning sliding rod 105 back to its original position. At the same time, the cleaning sliding rod 105 slides upward in the buffer groove 107 due to the push of the liquid discharged from the piston cylinder 204, so that the disc-shaped filter at the bottom of the cleaning sliding rod 105 is higher than the fluid transmission port 104, and impurities are retained in the disc-shaped filter at the bottom of the cleaning sliding rod 105, preventing impurities in the liquid from adhering to the piston cylinder 204 and the hollow plunger rod 205, thereby ensuring the normal operation of the equipment.
[0028] like Figures 1 to 9As shown, a cleaning short tube 108 is fixedly installed at the center of the transmission cover plate 101, and a plurality of attachment plates are evenly arranged inside the cleaning short tube 108 for filtering the coolant discharged from the cooling output groove 215 for easy recycling. The bottom of the cleaning short tube 108 is in contact with the top of the transmission support rod 214, and a positioning interface 102 is fixedly installed on the top of the transmission cover plate 101. The bottom of the positioning interface 102 is in contact with the top of the cleaning short tube 108 for fixing the cleaning short tube 108 between the transmission cover plate 101 and the transmission support rod 214.
[0029] Working principle: When liquid is transmitted, the transmission bevel rod 207 is driven to rotate by starting the external transmission system, and the rotation of the transmission bevel rod 207 drives the guide blade 208 to rotate, so that the external coolant is transmitted to the supporting outer cylinder body 201 through the injection hole on the sealing bottom plate 202, and driven by the guide blade 208 to flow into the annular guide groove at the bottom of the piston cylinder support block 203, during which it flows through the outer wall of the hollow plunger rod 205 to clean it, and then flows into the cylinder cleaning groove 210 through the cooling input port 212, cools the working piston cylinder 204, and is discharged through the cooling output port 213, and is filtered through the cleaning short tube 108 for recycling.
[0030] During operation, the rotation of the transmission inclined rod 207 drives the hollow plunger rod 205 to perform piston motion in the piston cylinder 204, draws external liquid into the buffer groove 107 and the piston cylinder 204, and discharges it through the fluid transmission port 104. During this period, the flow inertia of the liquid is buffered by the buffer plunger rod 209, thereby reducing the resistance encountered by the hollow plunger rod 205 during movement and scraping off the attachments on the inner wall of the hollow plunger rod 205.
[0031] The transmitted liquid flows from the fluid transmission port 104 into the buffer tank 107 through the control of the one-way transmission valve 106, and is filtered through the disc filter at the bottom of the cleaning sliding rod 105 and then discharged from the fluid transmission port 104 at the other end of the buffer tank 107, thereby realizing the transmission of the liquid.
