TECHNICAL FIELD
[0001] The utility model relates to the technical field of split case pump, concretely relates to a large flow split case pump water cooling system. BACKGROUND
[0002] Split case pump, also known as single-stage double-suction centrifugal pump. In order to avoid overheating of split case pump, the current designers add water cooling system on the pump shell to cool the internal structure of the pump shell. In the water cooling system of split case pump, the cooling liquid takes away the heat generated inside the split case pump motor through circulating flow, and the heat is dissipated to the air through the radiator, so as to maintain the normal working temperature of the split case pump motor.
[0003] At present, a double-suction split case pump with cooling structure (the authorized announcement number is CN219691834U) is disclosed in Chinese patent. The utility model discloses a fixed plate is installed, and the fixed plate can be stably supported by the supporting shell through the fixing component. The staff can connect the pipeline for conveying cooling water with the flange under the support of the supporting shell, so that the cooling water can enter the inside of the water delivery pipe through one of the pipelines for conveying cooling water, and then flow into the inside of the coil pipe through the water delivery pipe. Subsequently, the cooling water will flow around the outside of the motor through the coil pipe and flow into the inside of the drain pipe, and then be discharged to the outside through the drain pipe and another pipeline for conveying cooling water. The heat generated by the operation of the motor will be transferred to the cooling water flowing in the inside of the coil pipe, so that the cooling water can absorb and take away the heat. At the same time, the air will flow through the exhaust hole and the air inlet hole to perform heat dissipation work, so that the device can have the structure of providing cooling for the motor.
[0004] Since the above-mentioned device adopts spiral coiled pipe water cooling and bottom-up air cooling to cool the motor, although it can provide a larger heat dissipation area, due to the unidirectional flow of water flow and air flow, the local heat dissipation of the motor far from the water inlet side and the air inlet side will be lower than that of the motor close to the water inlet side and the air inlet side, which will increase the temperature difference gradient of the surface of the motor, resulting in uneven heat dissipation, and further affecting the service life of the motor.
[0005] Based on this, the utility model designs a large flow split case pump water cooling system to solve the above-mentioned problems. UTILITY MODEL CONTENTS

Obviously, the described embodiments are some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.
[0027] The present application will be further described below in combination with the embodiments.
[0028] In some embodiments, please refer to the drawings in the description Figures 1-4 A large-flow center-opening pump water cooling system, comprising a mounting cylinder 100, an air inlet hole 110 is formed at one end of the mounting cylinder 100, a plurality of air outlet holes 120 are formed at the other end of the mounting cylinder 100 in a ring shape, and a cooling mechanism 200 is installed inside the mounting cylinder 100.
[0029] It should be noted that the split case pump includes but is not limited to the pump body, the pump cover, the impeller, the shaft, the double suction sealing ring, the shaft sleeve, the bearing, the motor and other components, and its working principle is based on the rotation of the impeller to generate centrifugal force, thereby pushing the liquid. When the pump is started, the motor drives the pump shaft to rotate at high speed, so that the liquid in the impeller is thrown out under the action of centrifugal force, forming a certain pressure, thereby realizing the delivery of the liquid. In addition, the split case pump usually adopts the way of axial suction and radial discharge, so that the suction and discharge capacity of the pump is stronger, and it is suitable for occasions with large flow and high lift. The water cooling system needs to be actively sleeved and fixed on the surface of the split case pump motor before leaving the factory, and the liquid cooling pipe 210 needs to be coiled and fixed on the surface of the split case pump motor. Then the liquid outlet end of the liquid cooling pipe 210 and the liquid inlet end of the water chiller are connected together through the existing flange or joint, and then the liquid inlet end of the liquid cooling pipe 210 and the liquid outlet end of the water chiller are connected together through the existing flange or joint. The liquid outlet end and the liquid inlet end of the liquid delivery pump, the water chiller is a device for cooling liquid to the required temperature, and the liquid delivery pump is a commonly used device for delivering liquid at present. The split case pump, the water chiller and the liquid delivery pump are well-known technologies familiar to those skilled in the art. The specific model and power supply mode need to be selected by the user according to the actual demand, so the figure is not drawn.
[0030] The cooling mechanism 200 includes a liquid cooling pipe 210 and a fan 220, the liquid cooling pipe 210 is fixedly connected to the surface of the mounting cylinder 100, the water outlet end of the liquid cooling pipe 210 penetrates the mounting cylinder 100 and extends to the outside of the mounting cylinder 100, the fan 220 is fixedly connected to the inside of the air inlet hole 110, the air guide direction of the fan 220 is from the air inlet hole 110 to the air outlet hole 120, and the flow direction of the liquid cooling pipe 210 is from the air outlet hole 120 to the air inlet hole 110;
[0031] When the center-open pump is in normal operation, the water chiller cools the liquid in the water chiller to a corresponding temperature, and then the liquid is pumped into the liquid cooling pipe 210 by the liquid pump, and the liquid cooling pipe 210 transports the liquid from the air outlet hole 120 to the air inlet hole 110 through the installation cylinder 100. During the process of the liquid passing through the inside of the installation cylinder 100, the liquid quickly absorbs the heat emitted by the center-open pump motor through the liquid cooling pipe 210, so as to reduce the operating temperature of the center-open pump motor. In this process, the cooling effect of the liquid gradually decreases from the air outlet hole 120 to the air inlet hole 110, and the fan 220 stirs the surrounding air to form an air flow and guides the air flow from the air inlet hole 110 to the air outlet hole 120. During the process of the air flow passing through the gap between the installation cylinder 100 and the center-open pump motor, the air flow not only carries away the heat on the local surface of the center-open pump motor that is not covered by the liquid cooling pipe 210, but also reduces the heat passing through the surface of the liquid cooling pipe 210, which can also reduce the rate of the temperature rise of the liquid. In this process, the cooling effect of the air flow gradually decreases from the air inlet hole 110 to the air outlet hole 120, so that the surface cooling of the center-open pump motor is more uniform, thereby reducing the probability of failure of the center-open pump motor due to uneven temperature.
[0032] In some embodiments, as shown in Figures 2-4 As a preferred embodiment of the utility model, the liquid cooling pipe 210 is arranged in the partial cross-sectional shape of the installation cylinder 100 in a spiral shape, which can increase the contact area between the liquid cooling pipe 210 and the center-open pump motor, thereby improving the water cooling effect.
[0033] The surface of the liquid cooling pipe 210 is fixedly connected with the air guide pipe 230, one end of the air guide pipe 230 penetrates the liquid cooling pipe 210 and faces the air outlet side of the fan 220, the inside of the air guide pipe 230 is not communicated with the inside of the liquid cooling pipe 210, and the air guide pipe 230 can increase the indirect contact area between the air flow and the liquid in the liquid cooling pipe 210, thereby improving the cooling effect of the air flow on the liquid in the liquid cooling pipe 210.
[0034] The liquid cooling pipe 210 and the air guide pipe 230 are both made of red copper material, which can improve the heat conductivity of the liquid cooling pipe 210 and the air guide pipe 230.
[0035] The number of the air guide pipe 230 is not less than ten, and the air guide pipe 230 is arranged in a ring shape around the axis of the installation cylinder 100, which can increase the heat dissipation effect of the air flow on the liquid in the liquid cooling pipe 210.
[0036] The air inlet hole 110 and the air outlet hole 120 are both embedded with the dustproof net 240, and the dustproof net 240 is made of stainless steel material, which can filter the dust in the heat dissipation air flow and prevent the dust from entering the inside of the installation cylinder 100, thereby reducing the influence of the dust on the heat dissipation of the center-open pump motor.
[0037] In some embodiments, as shown inFigures 2-4 As shown, as a preferred embodiment of the utility model, the liquid cooling pipe 210 is fixedly connected with the mounting cylinder 100 and is annularly distributed with the air guide sheet 250, one end of the air guide sheet 250 is arranged on the air outlet side of the fan 220, the air guide sheet 250 is staggered with the air guide pipe 230, and the shape of the air guide sheet 250 is spiral, which can actively guide the airflow to the surface of the pump motor and the direction of the liquid cooling pipe 210, so as to improve the effect of airflow heat dissipation.
