Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a water pump installation and adjustment structure for resisting cavitation of water pumps. Background Art

[0002] During water pump operation, if the drawn-in liquid contains gas, or if the local pressure of the liquid drops below the saturated vapor pressure due to factors such as low suction pressure or excessive flow rate, the dissolved gas in the liquid will precipitate and form bubbles. When these bubbles enter the high-pressure area with the liquid flow, they will quickly burst and generate shock waves. This phenomenon is called "cavitation." Cavitation not only affects the operating efficiency of the water pump but also causes serious damage to the pump body. Currently, for water pump anti-cavitation protection, you can choose to install a degassing device in front of the pump, such as a gas-liquid separator and degassing tank, which can effectively remove gas from the drawn-in liquid and reduce the chance of cavitation.

[0003] When a water pump is used outdoors with a degassing device, the outdoor road surface is often not flat, which makes it difficult for the water pump to be in a horizontal state during operation. If the pump is installed at an angle, bubbles may easily gather on one side, especially at the pump inlet area, thereby increasing the probability of cavitation and shortening the service life of the water pump.

DETAILED DESCRIPTION

[0026] See also Figures 1-6A water pump installation and adjustment structure for anti-cavitation of a water pump includes a cart 1, a mounting mechanism 2 and an adjustment mechanism 3 are provided on the top of the cart 1, and two positioning mechanisms 4 are provided on the front and rear sides of the surface of the cart 1;

[0027] The mounting mechanism 2 includes a connecting base 201, a water pump 202 and a bracket 203 are fixed to the top of the connecting base 201, a telescopic hose 206 is connected to the water vapor inlet end of the gas-liquid separator 204, a connecting flange 208 is fixed to the surface of the telescopic hose 206, an automatic exhaust valve 205 is connected to the exhaust end of the gas-liquid separator 204, the liquid extraction end of the water pump 202 is connected to the liquid discharge end of the gas-liquid separator 204 through a pipeline, and a plurality of level gauges 207 are fixed to the top of the connecting base 201;

[0028] The connecting flange 208 is used to connect to a water source or other equipment. The gas-liquid separator 204 can separate the gas in the water flow and discharge the separated gas through the automatic exhaust valve 205. The liquid extraction end of the water pump 202 can extract the water flow after the gas-liquid separation inside the gas-liquid separator 204 to ensure that the water pump 202 can obtain an anti-cavitation effect. The other end of the water pump 202 can be connected to a pipeline to ensure that the water pump 202 can subsequently deliver water normally. The level meter 207 can monitor the horizontal condition of the connecting seat 201.

[0029] The adjustment mechanism 3 includes a base 301, with four first side plates 302 and a second side plate 304 fixed to the top of the base 301, a bearing seat 305 fixed to the top of the second side plate 304, a worm 303 rotatably connected to the surface of the first side plate 302, two worms 303, a rotating shaft 306 fixed to the inner wall of the bearing seat 305, a worm gear 307 fixed to the surface of the rotating shaft 306, the worm gear 307 meshing with the worm 303, a combination seat 308 fixed to the surface of the rotating shaft 306, and the top of the combination seat 308 fixedly connected to the bottom of the connecting seat 201;

[0030] Rotating the worm gears 303 on both sides can make the worm gears 303 drive the worm wheels 307 to rotate, and when the worm wheels 307 rotate, they can drive the rotating shaft 306 to rotate together, so that the rotating shaft 306 can drive the connecting seat 201 to rotate synchronously through the combination seat 308, so as to adjust the installation angle of the water pump 202 and the gas-liquid separator 204 on the surface of the connecting seat 201. During this period, you can observe the level 207 to ensure that the water pump 202 is in a horizontal state. By adjusting the connecting seat 201 to a horizontal state, it can be ensured that the water flow distribution at the inlet of the water pump 202 is more uniform, avoiding local flow rates that are too high or too low, thereby reducing the chance of bubble formation, and also ensuring that the water pump 202 operates in the best state, reducing additional vibration and noise caused by improper installation angles, thereby improving the efficiency of the water pump 202 and reducing wear.

[0031] Furthermore, the positioning mechanism 4 includes a protrusion 401, which is fixedly connected to the surface of the cart 1. A screw rod 402 is threaded through the surface of the protrusion 401. The bottom of the screw rod 402 is rotatably connected to a movable plate 403. The bottom of the movable plate 403 is hinged to a water tank 404. A friction pad 405 is fixed to the bottom of the water tank 404.

[0032] After the cart 1 moves to the required position, the screw rod 402 can be rotated to make the water tank 404 drive the friction pad 405 to move downward, and the friction pad 405 can come into contact with the ground. At the same time, the water tank 404 can rotate at the bottom of the movable plate 403 to make the friction pad 405 fit more closely to the ground, thereby increasing the friction between the cart 1 and the ground and reducing the movement of the cart 1 when the water pump 202 is working.

[0033] Furthermore, two guide rods 406 are fixed on the top of the movable plate 403, and the guide rods 406 slide through the protrusion 401;

[0034] The design of the guide rod 406 enables the movable plate 403 to move only up and down, thereby preventing the movable plate 403 from rotating.

[0035] Furthermore, a liquid inlet is provided on the top of the water tank 404, and a drain valve is connected to the surface of the water tank 404;

[0036] After the bottom of the friction pad 405 contacts the ground, water can be added to the water tank 404 through the liquid inlet, thereby increasing the weight of the water tank 404, thereby further improving the stability of the cart 1 when it stops moving, and the design of the drain valve ensures that the water in the water tank 404 can be discharged normally.

[0037] Furthermore, two support plates 310 are fixed on the top of the base 301, and the top of the support plate 310 is slidably connected to the support base 311, and the top of the support base 311 is fixedly connected to the bottom of the connecting base 201;

[0038] The support base 311 can move along with the connecting base 201 , and the support plate 310 can support the support base 311 , thereby improving the stability and bearing capacity of the connecting base 201 during movement.

[0039] Furthermore, a limit plate 312 is fixed to the surface of the support plate 310, and a limit slot is provided on the inner wall of the support seat 311 to cooperate with the limit plate 312, and the surface of the limit slot is slidably connected to the surface of the limit plate 312;

[0040] When the support seat 311 slides on the surface of the support plate 310, the limiting plate 312 will also slide on the inner wall of the limiting groove at the same time, so that the support seat 311 can obtain a left and right limiting effect, preventing the support seat 311 from falling off the surface of the support plate 310.

[0041] Furthermore, a scale line 313 is provided on the surface of the support base 311, and a pointer is provided on the surface of the support plate 310;

[0042] When the connecting base 201 rotates, the supporting base 311 moves along with the connecting base 201 . At this time, the rotation angle of the connecting base 201 can be more accurately determined by observing the pointer and the scale line 313 .

[0043] Furthermore, a transmission wheel 309 is fixed on the surface of the worm 303, and the transmission wheels 309 on both sides are connected by belt transmission;

[0044] By disposing the transmission wheel 309 , when the worm 303 on one side rotates, the transmission wheel 309 on this side can drive the worm 303 on the other side to rotate together through the cooperation of the belt and the transmission wheel 309 on the other side.

[0045] Furthermore, an extension block 314 is fixed to the surface of the rear first side plate 302, a pin rod 315 passes through the surface of the extension block 314, and a limiting hole for cooperating with the pin rod 315 is opened on the surface of the worm 303. The cross section of the pin rod 315 is arranged in a T-shaped structure;

[0046] After the worm 303 completes its rotation, the pin 315 can be inserted into the surface of the extension block 314 so that the pin 315 can enter the limiting hole on the surface of the worm 303, thereby limiting the worm 303 and preventing the vibration generated when the water pump 202 is working from causing the worm 303 to rotate on its own.

[0047] Furthermore, a support shell 209 is fixed to the surface of the bracket 203. A slot is provided on the surface of the support shell 209 to fit the connecting flange 208. A fastening knob 210 is threaded through the surface of the support shell 209.

[0048] When the telescopic hose 206 is not connected to a water source or other equipment, the connecting flange 208 can be placed in the slot inside the supporting shell 209, and then the tightening knob 210 can be rotated to limit the connecting flange 208, so that the telescopic hose 206 will not move on its own during the movement of the cart 1.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
