Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments.
In the description of the present invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present invention and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present invention.
Referring to fig. 1-4, a hydraulic oil pump with a monitoring function comprises a pump body 1 and a sealing cover 13, wherein an oil cavity 9 is formed in the pump body 1, one side of the oil cavity 9 is communicated with a sealing cavity 11, an impeller 10 is arranged in the oil cavity 9, the impeller 10 is fixedly connected with a driving shaft 5 through a flat key in the axial direction, a liquid outlet pipe 2 and a liquid inlet pipe 3 are symmetrically arranged on two sides of the pump body 1, a first hole 7 is formed in the liquid outlet pipe 2, a second hole 8 is formed in the inner wall of the liquid inlet pipe 3, the first hole 7 and the second hole 8 are communicated with the oil cavity 9, a pressure monitoring mechanism 17 is arranged on the liquid outlet pipe 2, a flow monitoring mechanism 16 is arranged on the liquid inlet pipe 3, the sealing cover 13 is arranged on the pump body 1 through a bolt, a bearing 14 is in the middle of the sealing cover 13 in an interference fit mode, a sealing plug 12 is arranged in the middle of the bearing 14 in an interference fit mode, a pin block 15 is fixedly connected to the center of the axial direction of the sealing plug 12, and a pin groove is formed in a position corresponding to the impeller 10 and the pin block 15.
Further, referring to fig. 1 to 2, a plurality of cooling fins 4 are installed at one end of the sealing cover 13 far from the pump body 1, and the height of the cooling fins 4 is continuously decreased along the center to the periphery, and the heat quantity of the middle part of the sealing cover 13 is higher than that of the periphery, so that the upper distribution of the cooling fins 4 can increase the heat conducting property of the middle part and increase the air flow capacity of the outside.
More preferably, referring to fig. 2, the inner diameter of the first hole 7 is continuously decreased along one side of the impeller 10, so that the pressure of the fluid in the first hole 7 is reduced from inside to outside, thereby increasing the discharge performance of the fluid.
More preferably, referring to fig. 2, the inner diameter of the second hole 8 is continuously increased along one side of the impeller 10, so that the pressure of the fluid in the second hole 8 is reduced from outside to inside, thereby increasing the pumping performance of the fluid.
More specifically, referring to fig. 4, the flow monitoring mechanism 16 includes a movable block 22, a connecting rod 20 and a return spring 18, a first cavity 21 is formed on the inner wall of the liquid inlet pipe 3, the return spring 18 is welded at the inner bottom end of the first cavity 21, the number of the movable blocks 22 is two, the connecting rod 20 is fixedly connected to the middle part of one end of each of the two movable blocks 22, which is close to each other, one of the movable blocks 22 is welded with the return spring 18, a circle of first flange 19 is integrally formed on the inner wall of the first cavity 21, the two movable blocks 22 are respectively located at two sides of the first flange 19, and the flow monitoring mechanism 16 is used for monitoring the liquid flow in the liquid inlet pipe 3, so that the flow velocity of the current fluid is intuitively known.
Wherein, the outer diameter of the movable block 22 is larger than the inner diameter of the first flange 19, so that the first flange 19 can limit the movement range of the movable block 22.
More specifically, referring to fig. 5, the pressure monitoring mechanism 17 includes an air bag 25, a second cavity 23 is formed on the inner wall of the liquid outlet pipe 2, the air bag 25 is located in the second cavity 23, a circle of second flanges 24 are integrally formed on the inner wall of the opening of the second cavity 23, and the pressure monitoring mechanism 17 is used for monitoring the fluid pressure in the liquid outlet pipe 2 and preventing the fluid pressure in the liquid outlet pipe 2 from being too high, so that the pipeline is broken.
Wherein the air bag 25 is of an oval configuration more reasonable.
When the invention is used, the driving shaft 5 is connected with the driving motor, the driving motor is started, the mechanical energy of the impeller 10 is converted into the kinetic energy of fluid, and the oil is conveyed.
When the fluid enters from the liquid inlet pipe 3, the inner diameter of the second hole 8 is gradually increased along one side of the impeller 10, and the inner diameter of one side close to the impeller 10 is small according to Bernoulli's law, so that the flow speed of the fluid passing through the inner diameter is high, the pressure inside the second hole 8 is smaller than the pressure outside, the flowability of the fluid from outside to inside is increased, and the movement of the impeller 10 is assisted and enhanced; similarly, since the inner diameter of the first hole 7 is continuously decreased along one side of the impeller 10, the pressure inside the liquid outlet pipe 2 is higher than the pressure outside, and the flowability of the fluid from inside to outside is increased.
In addition, when fluid enters the liquid inlet pipe 3, according to Bernoulli's law, the faster the fluid speed is, the smaller the pressure is, so that when the fluid speed in the liquid inlet pipe 3 is too fast, the tension of the movable block 22 overcoming the reset spring 18 is reduced along with the flow of the fluid, and at the moment, after the movable block 22 is observed to be reduced by external personnel, the too fast fluid speed can be judged, and the motor is controlled to be reduced.
Normally, the air bag 25 floats on the top end of the second cavity 23, and because the compression rate of the gas is higher than that of the liquid, when the pressure of the fluid in the liquid outlet pipe 2 is overlarge, the air bag 25 is compressed under force, and according to the Archimedes principle, the buoyancy force is equal to the gravity force of the discharged boiled water, so that the air bag 25 is compressed, the buoyancy force and the gravity force are not balanced any more, the air bag 25 drops, and when a worker judges that the air bag 25 drops, the motor can be controlled to relieve the pressure of the liquid outlet pipe 2.
In the present invention, unless explicitly specified and limited otherwise, the terms "cover," "flush," "connect," "secure," "distribute," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly, through intermediaries, or both, may be in communication with each other or in interaction with each other, unless expressly defined otherwise. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
