Description
Technical Field
[0001] The utility model relates to a pump in a tube, in particular to a highly adaptable silent pump in a tube. Background Art
[0002] A pump in a tube, also known as a planetary pump or a polygonal pump, is a centrifugal pump used to transport liquids. It is composed of multiple gears, forming a planetary gear structure, hence the name. The pump in a tube has the characteristics of small size, simple structure, and stable operation, and is widely used in fluid transportation in various industries.
[0003] The pump in the tube mainly uses the working principle of planetary gears to achieve the suction and discharge of liquid. It consists of a fixed outer gear and several inner gears rotating around the outer gear. The rotation of the inner gear changes the volume of the pump chamber to achieve liquid transportation.
[0004] The pump in the tube must be filled with liquid during safe and normal operation.

[0021] Advantages of the utility model:
[0022] 1) The utility model can effectively solve the problem of suction water supply in low water level scenes of water tanks, pools or open waters. The utility model uses a water level detection mechanism to detect water levels at different heights in the pipe pump, and then monitors the start and stop of the water pump motor through the control system, and controls the start and stop of the vacuum pump according to different water levels to adjust the water level in the pipe pump casing to meet the water filling volume standard for the pipe pump, and improve the practical effect of the pipe pump in low water level scenes.

[0024] 2) The utility model sets a water level detection mechanism and a water level control mechanism to cooperate, and uses the water level detection mechanism to detect different water levels, thereby adjusting the opening and closing of the vacuum pump and the water pump, and uses the vacuum pump to adjust the vacuum degree in the tube pump casing, and by pumping negative pressure, water enters the tube pump casing to meet the internal water content standard for normal operation of the tube pump. The connection between the tube pump casing and the water pump is prone to uneven force due to negative pressure, which causes vibration to the connection, and then causes wear of the connection, especially the sealing gasket. As the number of negative pressure pumping increases, air tightness problems occur, and air enters the tube pump casing, which ultimately affects the normal operation of the tube pump. Therefore, the utility model is provided with a corresponding particle damper at the connection between the casing of the in-pipe pump and the water outlet pipe of the water pump, and the mutual friction between the resistance particles in the particle damper dissipates energy to form a vibration damping zone above and below the sealing gasket, thereby effectively reducing the influence of vibration on the sealing gasket, avoiding the wear of the sealing gasket caused by vibration caused by uneven force due to repeated negative pressure extraction, ensuring the service life of the sealing gasket, and further ensuring the normal operation of the in-pipe pump.

A connection positioning flange 6 is fixedly connected to the outer wall of the water outlet pipe 5. The positioning flange 6 and the locking flange 2 are fixedly connected by a bolt combination and a sealing gasket 12, so that the water pump 3 is fixedly installed in the pipe-in-pump casing 1;
[0035] The water level detection mechanism 7 comprises a low water level electrode 701, a middle water level electrode 702 and a high water level electrode 703 which are connected to the control system 9 and are arranged from bottom to top in the pump casing 1 in the pipe;
[0036] The water level control mechanism 8 comprises a vacuum pump 803 connected to the pump-in-tube casing 1 through a corresponding ball valve 801 and a circulation pipe 802, wherein the circulation pipe 802 passes through the positioning flange 6 and extends to the inside of the pump-in-tube casing 1 at its end, and the vacuum pump 803 and the ball valve 801 are both electrically connected to the control system 9;
[0037] The particle damper 11 is used to reduce the vibration of the connection area between the positioning flange 6 and the locking flange 2.
[0038] The utility model can effectively solve the problem of suction water supply in low water level scenes of water tanks, pools or open waters. The utility model uses the water level detection mechanism 7 to detect the water levels at different heights in the pipe pump, and then monitors the start and stop of the water pump motor 4 through the control system 9, and controls the start and stop of the vacuum pump 803 according to different water levels to adjust the water level in the pipe pump casing 1, so as to meet the water filling volume standard for the pipe pump, and improve the practical effect of the pipe pump in low water level scenes.
[0039] The minimum water level electrode is used to detect whether the water level in the water tank, pool or open water area is lower than the minimum water level allowed for suction by the water pump 3. When the detected water level is lower than the minimum water level allowed for suction, the pump in the pipe stops; when the water level is between the middle water level M and the minimum water level ML, the vacuum pump 803 starts running; when the water level is lower than the low water level L, the water pump 3 stops running; the vacuum pump 803 works until the water level rises to the middle water level M, and the water pump 3 can start running; when the water level rises to the high water level H, the vacuum pump 803 stops running.

[0041] The utility model sets the cooperation of the water level detection mechanism 7 and the water level control mechanism 8, uses the water level detection mechanism 7 to detect different heights of the water level, and then adjusts the opening and closing of the vacuum pump 803 and the water pump 3, uses the vacuum pump 803 to adjust the vacuum degree in the tube pump casing 1, and makes water enter the tube pump casing 1 by pumping negative pressure, so as to meet the internal water content standard for the normal operation of the tube pump. The connection between the tube pump casing 1 and the water pump 3 is prone to uneven force due to the negative pressure, which causes vibration to the connection, and then causes wear of the connection, especially the sealing gasket 12. As the number of negative pressure pumping increases, air tightness problems occur, and air enters the tube pump casing 1, which ultimately affects the normal operation of the tube pump. Therefore, the utility model is provided with a corresponding particle damper at the connection between the in-pipe pump casing 1 and the water outlet pipe 5 of the water pump 3. The mutual friction between the damping particles 1101 in the particle damper dissipates energy to form a damping zone above and below the sealing gasket 12, thereby effectively reducing the influence of vibration on the sealing gasket 12, avoiding the wear of the sealing gasket 12 caused by vibration caused by uneven force due to repeated negative pressure extraction, ensuring the service life of the sealing gasket 12, and further ensuring the normal operation of the in-pipe pump.

The cable 14 is sleeved in the corresponding food-grade silicone tube 15, and the two ends of the inner side of the food-grade silicone tube 15 are provided with corresponding cable lead-out tubes 16, and the two ends of the outer side of the food-grade silicone tube 15 are provided with clamps 17 for fixing the food-grade silicone tube 15.

[0045] At least one pump-in-tube support 18 that cooperates with the positioning flange 6 and is used to strengthen and fix the water pump 3 is fixedly connected to the outer side wall of the motor 4 .

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
