Description

Technical Field

[0001] The invention relates to the technical field of high-lift water pumps, in particular to a water pump capable of increasing the lift. Background Art

[0002] A high-lift water pump is a pump device that can overcome greater resistance and lift water from a low place to a higher place. Its lift capacity is usually much higher than that of an ordinary water pump. Therefore, it is widely used in occasions that require high-lift water supply. High-lift water pumps are widely used in industrial production. In order to meet specific process requirements, high-lift water pumps can be used to lift water to a specified location.

[0003] When working, the high-lift water pump uses the rotating shaft to drive the impeller to rotate. The centrifugal force generated by the rotation of the impeller lifts the water. When the rotating shaft rotates, it will drive the inner ring of the bearing to rotate, so that the bearing balls and the outer ring of the bearing will be subject to greater friction and wear. Long-term lack of lubrication will cause energy loss of the high-lift water pump, so the water pump needs to increase the input power when conveying liquid.

[0004] Current high-lift water pumps need to be shut down for lubrication of bearings, which makes it difficult to ensure that lubricating oil is added to the bearings regularly. Moreover, when adding lubricating oil to the bearings, it cannot be added in a quantitative manner. Adding too much lubricating oil will increase the friction and resistance inside the bearings, making it impossible for the bearings to operate normally, which may cause overheating and damage to the bearings, reduce the lubricating effect of the lubricating oil on the bearings, and also consume the energy of the high-lift water pump. Therefore, we propose a water pump that can increase the head. Summary of the invention

[0036] Working principle: When transporting water from a low place to a high place, a high-lift water pump is required for transportation. The driving motor 101 drives the driving shaft 103 to rotate. When the driving shaft 103 rotates, it drives the inner ring and the ball of the bearing 108 to rotate (to ensure the temperature of the driving shaft 103). The driving shaft 103 drives the impeller 105 to rotate, and the water enters the casing 104 from the water inlet pipe 106. The centrifugal force generated by the rotation of the impeller 105 lifts the water from the water outlet pipe to a high place (the water inlet pipe 106 and the water outlet pipe are both connected to the water pipe, which is the prior art). The rotation of the ball and the outer ring of the bearing 108 will be subject to greater friction and wear. If the bearing 108 is not properly lubricated for a long time, the friction of the driving shaft 103 will be aggravated, causing energy loss of the high-lift water pump, so the bearing 108 needs to be lubricated regularly.

[0037] The infrared temperature sensor 8 senses that the temperature of the bearing 108 is too high and reaches a peak value. Due to the increase in friction heat caused by poor lubrication of the bearing 108, lubricating oil needs to be added at this time. The locking mechanism 206 opens the first rotating shaft 207 (the locking mechanism 206 uses the cooperation of the locking block and the locking wheel to lock and open the first rotating shaft 207. This is a prior art and will not be described in detail here). The rotation of the impeller 105 will generate centrifugal force. The water entering through the water inlet pipe 106 will be subjected to the centrifugal force, so that the water will drive the fan blades 21 1 rotates, the fan blade 211 drives the second rotating shaft 212 to rotate, the second rotating shaft 212 drives the active bevel gear 210 to rotate, the active bevel gear 210 drives the driven bevel gear 208 to rotate, the driven bevel gear 208 drives the first rotating shaft 207 to rotate, the first rotating shaft 207 drives the disk 204 to rotate, the connecting rod 203 drives the guide block 202 to move on the outer wall of the guide rail 201, the guide block 202 drives the rack 200 to move, the rack 200 drives the gear 301 to rotate, the gear 301 drives the screw rod 305 to rotate, and the slider 30 3 and the sliding rod 302, the sliding block 304 moves on the outer wall of the screw rod 305, the sliding block 304 drives the first extrusion block 306 to move, the inclined surface of the first extrusion block 306 can squeeze the inclined surface of the first movable block 307, the first movable block 307 is squeezed and moves upward, the first movable block 307 drives the extrusion rod 316 to move upward, the extrusion rod 316 drives the lifting plate 310 to move upward, the lifting plate 310 stretches the spring 309, the lifting plate 310 drives the piston rod 312 to move downward, the piston The rod 312 drives the piston head 314 to move downward, because the disc 204 drives the connecting rod 203 to make a circular motion, so that the guide block 202 drives the rack 200 to move back and forth, and the extrusion block 306 also moves back and forth on the outer wall of the screw rod 305, so that the piston rod 312 drives the piston head 314 to move up and down in the oil box 313 under the action of the elastic force of the spring 309, and the piston head 314 can squeeze the lubricating oil, and the lubricating oil enters the cylinder 503 along the oil supply pipe 315 and the first one-way valve 500; As the lubricating oil in the cylinder 503 gradually rises, the lubricating oil will squeeze the floating plate 506 and drive it to rise. The floating plate 506 drives the second squeezing block 507 to move upward. After the second squeezing block 507 rises to a certain position, it squeezes the inclined surface of the second movable block 509. The second movable block 509 drives the movable rod 501 to squeeze the movable plate 513. The movable plate 513 stretches the return spring 512. The movable plate 513 drives the squeezing head 516 to squeeze the pressure sensor 515. The pressure sensor 515 is squeezed and transmits a signal to the external controller. The locking mechanism 206 locks the first rotating shaft 207, and the piston head 314 stops working, so that the lubricating oil entering the cylinder 503 can be quantitatively controlled. Then the hydraulic cylinder 4 drives the extrusion plate 6 to squeeze the pressure plate 505 downward, and the pressure plate 505 squeezes the float rod 504 and the floating plate 506. The floating plate 504 squeezes the lubricating oil. The lubricating oil passes through the second one-way valve 502 and is lubricated to the bearing 108 under the action of the refueling pipe 501, so as to achieve quantitative refueling and improve the lubrication effect of the bearing 108. Good lubrication can reduce the friction resistance of the bearing 108 during operation.
