DETAILED DESCRIPTION

[0023] The technical solution provided by the present invention is further described below in conjunction with the accompanying drawings and according to specific implementation methods.

[0024] like Figures 1 to 8 As shown, a wear-resistant high-pressure plunger pump includes a driving mechanism 1, which includes a fixed outer frame 101, a plurality of plunger cylinders 2 are fixedly installed at the front end of the fixed outer frame 101, a plurality of heat dissipation transmission pipes 102 are fixedly installed on the outer wall of the fixed outer frame 101, and a transmission tail pipe 103 is fixedly installed at the rear end of the fixed outer frame 101. The heat dissipation transmission pipe 102 is connected to the transmission tail pipe 103, and the heat dissipation transmission pipe 102 is used to transmit water flow and cool the equipment.

[0025] like Figures 1 to 8 As shown, the plunger cylinder 2 includes a plunger cylinder body 201, which is fixedly mounted at the front end of the fixed outer frame 101. An upper and lower channel is arranged in the plunger cylinder body 201, and the channel is semi-cylindrical. An inlet valve 203 and a drain valve 207 are fixedly mounted at both ends of the semi-circular channel of the plunger cylinder body 201, respectively. A one-way plunger head 208 is installed in the channel of the plunger cylinder body 201 for transverse sliding. A plurality of balls are inlaid on the outer wall of the one-way plunger head 208. The balls on the outer wall of the one-way plunger head 208 are rollingly matched with the inner wall of the channel in the plunger cylinder body 201. A third plunger arm 206 is fixedly mounted at the left and right ends of the one-way plunger head 208, respectively. A second plunger arm 205 is slidably mounted at the front end of the third plunger arm 206. A first plunger arm 204 is slidably installed at the front end of 205, and the front ends of the two first plunger arms 204 are fixedly connected to the two ends of the internal channel of the plunger cylinder 201 respectively. The axial cross-sections of the first plunger arm 204 and the third plunger arm 206 are C-shaped, and the axial cross-section of the second plunger arm 205 is S-shaped. The first plunger arm 204 and the second plunger arm 205 are fitted and slid with each other, which can improve the sealing performance of the equipment during operation. A sealing rubber ring 213 is fixedly installed at the front end of the second plunger arm 205 and the third plunger arm 206. Through the cooperation of multiple sections of telescopic tube walls and the one-way plunger head 208, the sliding distance of each section of the telescopic tube can be reduced, thereby reducing the friction generated in each action cycle, thereby improving the service life of the equipment workpiece.

[0026] like Figures 1 to 8 As shown, a transmission plate 209 is fixedly installed at the bottom of the one-way plunger head 208, and a gear pattern is provided at the bottom of the transmission plate 209. A transmission gear column 210 is installed in the plunger cylinder body 201 for horizontal rotation. The gear pattern at the bottom of the transmission plate 209 meshes with the transmission gear column 210. A transmission rod 211 is fixedly installed on the transmission plate 209, and a transmission roller 212 is fixedly installed at the rear end of the transmission rod 211. A driving motor 104 is fixedly installed at the rear end of the fixed outer frame 101, and an inner driving ring 106 is installed at the front end of the driving motor 104 for horizontal sliding. The front end of the fixed outer frame 101 is fixedly installed with an adjustable telescopic rod 107, which is rotatably matched with the front end of the inner drive ring 106. The outer drive ring 105 is fixedly installed on the outer ring of the inner drive ring 106. The front ends of the outer drive ring 105 and the inner drive ring 106 are beveled surfaces, and the angles of the beveled surfaces of the outer drive ring 105 and the inner drive ring 106 are opposite. The outer drive ring 105 is in contact with the transmission roller 212 at the rear end of the transmission rod 211 in the lower channel of the plunger cylinder body 201. 106 contacts and cooperates with the transmission roller 212 at the rear end of the transmission rod 211 in the upper channel in the plunger cylinder 201. The outer drive ring 105 and the inner drive ring 106 are used to push the two transmission rods 211 to move alternately, driving the two one-way plunger heads 208 in the plunger cylinder 201 to slide back and forth alternately to perform uninterrupted water pumping. During this period, the outer drive ring 105 and the inner drive ring 106 are controlled to contact or separate from the transmission roller 212 by starting and adjusting the telescopic rod 107, thereby controlling the intermittent stop and start of the equipment.

[0027] like Figures 1 to 8 As shown, a transmission pipe 202 is fixedly installed at the rear end of the plunger cylinder 201 , the front end of the transmission pipe 202 is connected to the two semicircular channels in the plunger cylinder 201 , and the rear end of the transmission pipe 202 is connected to the heat dissipation transmission pipe 102 .

[0028] Working principle: When the device is enabled to transmit liquid, first start the adjustment telescopic rod 107 to drive the inner drive ring 106 to slide at the front end of the drive motor 104, control the outer drive ring 105 and the inner drive ring 106 to contact and cooperate with the transmission roller 212, and then start the drive motor 104 to drive the outer drive ring 105 and the inner drive ring 106 to rotate, and drive the transmission rod 211 to slide alternately in the plunger cylinder 201 through the outer drive ring 105 and the inner drive ring 106, drive the one-way plunger head 208 to slide in the channel in the plunger cylinder 201, and cooperate with the third plunger arm 206, the second plunger arm 205 and the first plunger arm 204 to extract the liquid. The plunger formed by the telescopic pipe can reduce the sliding distance in each cycle when the device is working, thereby reducing the wear of the plunger during work and increasing the service life of the equipment.

[0029] During this period, the contact and separation of the outer drive ring 105 and the inner drive ring 106 with the transmission roller 212 can be controlled by adjusting the telescopic rod 107 as needed, and the device can be stopped or started in time when working, thereby improving the controllability of the device.
