Detailed Description
Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the application.
Referring to fig. 1, one embodiment of the present application provides a water pump assembly.
In the present embodiment, the water pump assembly includes a water pump 100, a water inlet pipe 200, and an exhaust mechanism 300, the water inlet pipe 200 communicating with a water inlet 110 of the water pump 100; the exhaust mechanism 300 is mounted to the water inlet pipe 200 and is close to the water inlet 110, and the exhaust mechanism 300 is used for collecting and exhausting the gas in the water inlet pipe 200.
In this embodiment, the water pump assembly may be applied to an integrated chiller system for pumping cooling water from a cooling plant and outputting the cooling water to a condenser. The cooling device may be a water pump cooling tower, etc., and the water pump 100 is a cooling water pump. The specific structure and principle of the water pump cooling tower and the cooling water pump are already mature technology, and the detailed description of this embodiment is omitted here. Of course, the water pump cooling tower and the water pump 100 may be other types of water pumps, and the present embodiment is not limited thereto.
In some embodiments, one end of the water inlet pipe 200 may be connected to the cooling tower, and the other end of the water inlet pipe 200 is connected to the water inlet 110 of the water pump 100. The cooling water flows from the water pump cooling tower into the water inlet pipe 200, and then flows from the water inlet pipe 200 into the water pump 100.
It should be noted that, the cooling water pump has a larger flow rate due to a larger selection of the cooling water pump or a larger selection of the lift, and a lower water pressure at the inlet of the water pump due to a larger flow rate at the inlet of the water pump. Because the cooling water temperature is lower, the cooling water is easy to vaporize when the water pressure is lower, and cavitation is caused.
In the present embodiment, the exhaust mechanism 300 is used to collect gas in the cooling water flowing in the water inlet pipe 200. After the cooling water flows into the exhaust mechanism 300, gas is trapped and a portion of the water flows into the nozzle 110. The venting mechanism 300 may periodically vent the collected gas to free space to facilitate continued collection of the gas. Since the cooling water flowing into the water pump 100 has no gas, cavitation of the water pump 100 can be prevented.
According to the water pump assembly of the present application, the exhaust mechanism 300 is provided at the position of the water inlet pipe 200 near the water inlet 110 of the water pump 100 to collect and exhaust the gas, thereby reducing cavitation generated in the water pump 100 by the gas and avoiding damage to the water pump 100.
Referring to fig. 2, in one embodiment of the present application, the air discharging mechanism 300 includes an air storage bag 310 and an air discharging valve 320, the air storage bag 310 is formed above the water inlet pipe 200, and an air storage chamber 311 is formed, the air storage chamber 311 being in communication with the water inlet pipe 200; the exhaust valve 320 is mounted to the gas storage bag 310 and communicates with the gas storage chamber 311.
It will be appreciated that the cooling water in the inlet pipe 200 generally flows along the upper side of the inlet pipe 200 with the gas generated at low pressure. Thus, the gas storage bag 310 is disposed above the water inlet pipe 200, so that the gas flows upward into the gas storage bag 310 when the cooling water flows under the gas storage bag 310.
In some embodiments, an opening may be provided above the water inlet pipe 200, through which the storage chamber 311 communicates with the water inlet pipe 200. The water inlet pipe 200 and the air storage bag 310 may be integrally formed, or the air storage bag 310 may be fixed to the water inlet pipe 200 by welding or the like.
In some embodiments, a membrane may also be provided at the opening above the inlet tube 200, the membrane separating the inlet tube 200 and the gas storage bag 310, and the membrane being configured to allow gas to pass therethrough while isolating the passage of the body of water. As the cooling water passes under the membrane, the water still flows along the inlet pipe 200, and the gas passes through the membrane into the gas holder 310.
In the present embodiment, the exhaust valve 320 is disposed above the air storage bag 310 and is located at the highest position of the air storage chamber 311. The vent valve 320 may collect gas within the gas holder 310. When the gas enters the exhaust valve 320 and the valve cavity of the exhaust valve 320 is accumulated at the upper part of the exhaust valve 320, the pressure rises along with the increase of the gas in the valve, and when the gas pressure is higher than a certain pressure, the exhaust valve 320 opens the exhaust port; after the gas is exhausted, the pressure is reduced, and the exhaust port is closed.
It will be appreciated that when negative pressure is generated in the air storage bag 310, the exhaust valve 320 opens the exhaust port, and since the external atmospheric pressure is greater than the pressure of the air storage chamber 311 at this time, the atmosphere will enter the air storage chamber 311 through the exhaust port, preventing the harm of the negative pressure.
In one embodiment of the present application, the exhaust mechanism 300 further includes a first baffle 330, the first baffle 330 is installed at an upper side inside the water inlet pipe 200 and is located at a front side of the air reservoir 310 in the water inlet direction, and a plurality of first through holes 331 are provided in the first baffle 330.
It should be noted that, the fluid in the water inlet pipe 200 passes through the first baffle 330 and then passes under the air storage bag 310. The first baffle 300 serves as a barrier to fluid above the inlet pipe 200 and a portion of the body of water flows downwardly below the first baffle 330. Since the gas is held at the water inlet pipe 200, the gas is mainly gathered from the through holes of the first baffle 330 under the gas storage bag 310 and flows into the gas storage bag 310.
In this embodiment, the opening above the water inlet pipe 200 may not be provided with a diaphragm, that is, the mixed fluid of the gas and the water may be contained in the gas storage bag 310. Since the gas storage bag 310 is located above the water inlet pipe 200, the gas storage chamber 311 is mainly filled with gas. After the gas has accumulated to a certain amount, it is exhausted through an exhaust valve 320.
Referring to fig. 3, as an example, the upper side edge of the first baffle 300 is curved in profile, and the upper side edge abuts against the inner pipe wall of the water inlet pipe 200; the contour of the lower side edge of the first barrier 300 is a horizontal straight line. The first through holes 331 may be circular and uniformly arranged on the first barrier 300. Of course, the first through holes 331 may be square, or the like, and the first through holes 331 may be arranged on the first baffle 300 in an irregular arrangement, which is not limited in this embodiment.
In one embodiment of the present application, the exhaust mechanism further includes a second baffle 340, the second baffle 340 is installed at an upper side in the water inlet pipe 200 and is located at a rear side of the air reservoir 310 in the water inlet direction, and a plurality of second through holes 341 are formed in the second baffle 340.
It should be noted that, after the fluid in the water inlet pipe 200 passes through the first baffle 330 and then passes under the air storage bag 310, if a small amount of escaping air still passes through the impact of the second baffle 340, the fluid returns to the air storage bag 310, so as to prevent the air from entering the water inlet 110 of the water pump 100.
Referring to fig. 4, as an example, the upper side edge of the second baffle 340 is curved in profile, and the upper side edge abuts against the inner pipe wall of the water inlet pipe 200; the lower side edge profile of the second baffle 340 is a horizontal straight line. The second through holes 341 may be circular and uniformly arranged on the second barrier 340. Of course, the second through holes 341 may be square, or the like, and the second through holes 341 may be arranged on the second baffle 340 in an irregular arrangement, which is not limited in this embodiment.
In one embodiment of the present application, the first through holes 331 and the second through holes 341 are arranged to be staggered in the water inlet direction.
It can be appreciated that, because the first through holes 331 and the second through holes 341 are staggered, after the fluid passes through the first through holes 331, if the fluid flows to the second baffle 340 in the original running direction, the fluid will be blocked by the solid portion of the second baffle 340, so that the gas collecting effect can be improved.
In the present embodiment, when the fluid in the water inlet pipe 200 passes through the first baffle 300 and the second baffle 340, the fluid passing through the two baffles is extruded, so that the flow rate of the fluid between the first baffle 300 and the second baffle 340 is increased, the kinetic energy is increased, so that the pressure above the fluid between the first baffle 300 and the second baffle 340 is reduced, a vacuum area is formed, and thus the gas is introduced into the gas holder 310.
In one embodiment of the present application, the water pump assembly further includes a first connection pipe 400, the first connection pipe 400 being installed between the water inlet pipe 200 and the water inlet 110 of the water pump 100, the first connection pipe 400 having a first transition section having a pipe diameter gradually decreasing in the water inlet direction, the first transition section being connected to the water inlet 110 of the water pump 100.
It will be appreciated that the front end of the water inlet 110 of the water pump 100 has an enlarged pipe diameter portion, which reduces the kinetic energy of the cooling water entering the water pump 100 and increases the static pressure of the cooling water, so that the vaporization of the cooling water generates gas.
In some embodiments, the pipe diameters of the two ends of the first connecting pipe 400 may be the same, and the pipe diameter of the middle part of the first connecting pipe 400 is larger than the pipe diameters of the two ends. The kinetic energy of the cooling in the middle of the first connecting pipe 400 is low and is not easily vaporized.
In one embodiment of the present application, the pipe diameter of the water inlet pipe 200 is larger than the diameter of the water inlet 110, and the pipe diameter of the first connection pipe 400 at the side connected to the water inlet pipe 200 is larger than the pipe diameter at the side connected to the water outlet 110.
In the present embodiment, the pipe diameter of the first connection pipe 400 is gradually reduced in the water inlet direction, the smaller pipe diameter side is connected to the water inlet 110 of the water pump 100, and the larger pipe diameter side is connected to the water inlet pipe 200. The water inlet pipe 200 has a constant pipe diameter along the axial direction and is larger than the diameter of the water inlet 110. The front ends of the water inlets 110 of the water pump 100 are all enlarged pipe diameter parts, which is beneficial to increasing the static pressure of the cooling water, so that the vaporization of the cooling water generates gas.
In some embodiments, the radial cross-sectional line of the transition section may be a straight line, an arc line, a wavy line, or the like.
In one embodiment of the present application, the water pump assembly further includes a water outlet pipe 500 and a second connection pipe 600, the second connection pipe 600 being installed between the water outlet pipe 500 and the water outlet 120 of the water pump 100, the second connection pipe 600 having a second transition section with a gradually increasing pipe diameter in the water outlet direction, the second transition section being connected to the water outlet 120 of the water pump 100.
It will be appreciated that the rear end of the water outlet 120 of the water pump 100 has an enlarged pipe diameter portion, which reduces the kinetic energy of the cooling water in the whole system, increases the static pressure of the cooling water, and thus the vaporization of the cooling water generates gas.
In some embodiments, the pipe diameters of the two ends of the second connection pipe 600 may be the same, and the pipe diameter of the middle portion of the second connection pipe 600 is larger than the pipe diameters of the two ends. The kinetic energy of cooling in the middle of the second connection pipe 600 is low and vaporization is not easy.
In other embodiments, the pipe diameter of the second connection pipe 600 is gradually increased in the water outlet direction, and the smaller pipe diameter side is connected to the water outlet 120 of the water pump 100, and the larger pipe diameter side is connected to the water outlet pipe 500. The outlet pipe 500 has a constant pipe diameter along the axial direction and is larger than the diameter of the water outlet 120. The rear ends of the water outlets 120 of the water pump 100 are all enlarged pipe diameter parts, which is beneficial to increasing the static pressure of the cooling water, so that the cooling water is vaporized to generate gas.
In some embodiments, the outlet of the water inlet pipe 200 is further provided with an exhaust mechanism 300, the outlet of the water inlet pipe 200 is connected to one end with a larger pipe diameter in the first connecting pipe 400, one end with a smaller pipe diameter in the first connecting pipe 400 is connected to the water inlet 110 of the water pump 100, the water outlet 120 of the water pump 100 is connected to one end with a smaller pipe diameter in the second connecting pipe 600, and the second connecting pipe 600 is connected to the water outlet pipe 500 with one end with a larger pipe diameter.
According to the water pump assembly of the present embodiment, the kinetic energy of the cooling water is reduced through the first connection pipe 400 before the cooling water enters the water pump, the static pressure of the water before entering the water pump 100 is increased, and vaporization of the cooling water before entering the pump 100 is prevented; even if vaporization occurs, the gas is collected and discharged through the gas discharge mechanism 300, so that cavitation generated in the pump body by the gas is reduced, and the water pump 100 is damaged; through multiple design, the cavitation of the water pump 100 by the gas is prevented, the generation of noise and cavitation of the water pump 100 are avoided, a foundation is laid for long-term reliable operation of the water pump 100, the service life of the water pump 100 is prolonged, and the later maintenance cost of the water pump 100 is reduced.
