Description

Technical Field

[0001] The present application relates to the field of clutch water pumps, and more particularly, to an open impeller type electronically controlled silicone oil clutch water pump with a flow guiding function. Background Art

[0002] The cooling system is an important part of the engine. During engine operation, the parts in contact with high-temperature combustion gas or exhaust are strongly heated, and the cooling system is required to dissipate excessive heat from these parts. Otherwise, various adverse consequences will occur, such as: deterioration of lubricating oil, destruction of the normal oil film; expansion of heated parts, destruction of the normal clearance of moving pairs; decline in the mechanical properties of parts and even failure. In addition, overcooling should also be avoided, otherwise, combustion will be poor, emissions will increase, and fuel economy will decrease; the viscosity of engine oil will increase, the friction loss of moving pairs will intensify, the engine operation will be rough, the engine power will decrease, and the service life will be reduced. The engine cooling system is divided into air cooling and water cooling. The one with air as the cooling medium is called the air cooling system, and the one with coolant as the cooling medium is called the water cooling system. Most automobile engines use water cooling systems, and they are forced closed-loop water cooling systems. The water pump is a key part of the water cooling system of a water-cooled engine and plays a crucial role. For the above-mentioned forced closed-loop water cooling system, the water pump is its power source. In an automobile engine, the water pump is mostly a centrifugal pump. By rotating the water pump, the pressure of the coolant is increased, and the coolant is forced to circulate in the engine.

[0003] Currently, the electronically controlled silicone oil clutch water pump does not have a flow guiding function, and the outlet of the pump is often in a right-angle shape. When the condensate reaches the outlet of the water pump, it will generate a large impact and eddy current, causing impact loss. Especially when the coolant reaches the outlet after diffusing, its kinetic energy is the largest, and this impact loss is particularly obvious, resulting in low efficiency of the water pump, consuming more engine power, being insufficient in energy conservation and environmental protection. At the same time, the current housing of the electronically controlled silicone oil clutch water pump is installed and fixed to the engine housing using screws or bolts, and both installation and disassembly require the assistance of an external wrench or screwdriver, making subsequent disassembly, repair, or replacement of the water pump relatively difficult.

[0004] How to invent an open impeller type electronically controlled silicone oil clutch water pump with a flow guiding function to improve these problems has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] To make up for the above deficiencies, the present application provides an open impeller type electronically controlled silicone oil clutch water pump with a flow guiding function, aiming to improve the problems that the current electronically controlled silicone oil clutch water pump does not have a flow guiding function and is not convenient for quick installation with the engine housing.

[0006] An embodiment of the present application provides an open impeller type electronically controlled silicone oil clutch water pump with a flow guiding function, including a pump housing mounting assembly and an impeller transmission assembly.

[0007] The pump housing mounting assembly includes insertion rods and a pump housing. There are two insertion rods, and cruciform slots are respectively opened on both sides of the two pump housings close to the insertion rods. The insertion rods are inserted into the corresponding cruciform slots. Clamping frames are also inserted into the cruciform slots. Through holes are opened on the insertion rods. The two clamping frames are respectively inserted and fixed with the two insertion rods through the corresponding through holes. Springs are connected in pairs on the clamping frames, and the outer ends of the springs are fixedly connected to the pump housing. The impeller transmission assembly includes a driving member, a driven member and an open impeller. The driving member is rotatably connected to the inner cavity of the pump housing. The driving member is movably matched with the driven member. The open impeller is connected to the outer end of the driven member, and the open impeller rotates through the cooperation of the driving member and the driven member. A flow guiding plate is also provided at the coolant output end of the pump housing itself.

[0008] In the above implementation process, one end of the insertion rod is pre-welded to the external engine housing. When it is necessary to install the pump housing on the external engine housing, pull the two clamping frames outward, insert the two insertion rods into the corresponding cruciform slots, and then release the two clamping frames. The tightening force of the springs can make the two clamping frames stably inserted into the corresponding through holes, indirectly improving the disassembly and assembly efficiency of the pump housing and the external engine housing. When disassembling the pump housing, only need to pull the two clamping frames outward and make the two insertion rods disengage from the corresponding cruciform slots, which is beneficial to the subsequent disassembly, repair and replacement of the pump housing and its associated structures, changing the situation that it was inconvenient to disassemble and assemble when using screws or bolts to install the pump housing on the engine housing in the past; the cooperation of the driving member and the driven member can control the high-speed rotation of the open impeller to convey the pumped coolant. The flow guiding plate can reduce the impact and eddy current formed at the original outlet of the coolant, reduce the water outlet resistance, reduce the impact loss, improve the hydraulic efficiency of the water pump, reduce the power consumption of the water pump, improve the fuel economy of the engine, and the design structure of the open impeller is simple, and the manufacturing cost is lower than that of the closed impeller.

[0009] In a specific implementation scheme, the driving member includes a driving shaft, a bearing and a driving plate. The inner and outer rings of the bearing are respectively in interference fit with the driving shaft and the inner cavity of the pump housing.

[0010] In the above implementation process, the setting of the bearing enables the driving shaft to rotate along with the output end of the external engine, and the pump housing will not rotate when rotating.

[0011] In a specific embodiment, the drive shaft is fixed to the output shaft of an external engine, the driving plate is connected to one end of the drive shaft, and an external gear ring is provided on the outer wall of the driving plate.

[0012] In the above implementation process, the connection manner between the other end of the drive shaft and the output end of the engine is a prior art and will not be elaborated herein. The driving plate is fixed to one end of the drive shaft by screws. Driven by the rotation of the drive shaft, the driving plate and the external gear ring will also rotate at the same speed therewith.

[0013] In a specific embodiment, the driven member includes a driven shaft, a driven plate, and a pair of moving rings and static rings arranged in pairs, and the driven shaft penetrates through the internal cavity of the pump housing.

[0014] In a specific embodiment, the two moving rings are respectively connected to both sides of the outer wall of the driven shaft, the two static rings are respectively fixedly connected to both sides of the inner wall of the pump housing, sealing rings that are attached to and fit with the corresponding moving rings are respectively adhered to the two static rings, and the two static rings are respectively connected to the moving rings in an actively sealed manner through the corresponding sealing rings.

[0015] In the above implementation process, the connection manners of the static ring and the moving ring to the pump housing and the driven shaft respectively are prior arts. The cooperation of the static ring, the moving ring, and the sealing ring can reduce the mixing of the silicone oil in the oil storage cavity with the coolant outward, thereby indirectly increasing the sealing performance of the oil storage cavity.

[0016] In a specific embodiment, the driven plate is fixedly connected to one end of the driven shaft, a circular concave cavity is formed on the side of the driven plate close to the driving plate, an internal gear ring is provided on the inner wall of the circular concave cavity, and the driving plate extends into the circular concave cavity.

[0017] In a specific embodiment, the driven plate is provided with a pair of silicone oil inlet pipes communicating therewith, and electromagnetic valves are also installed on both of the two silicone oil inlet pipes.

[0018] In the above implementation process, the electromagnetic valve can be used to control the opening and closing of the silicone oil inlet pipe, so as to facilitate the control of the silicone oil in the oil storage cavity entering the working cavity.

[0019] In a specific embodiment, a storage cavity is formed between the side of the driven plate far from the driving plate and the inner wall of the pump housing and the outer wall of the driven shaft, a working cavity is formed between the side of the driven plate close to the driving plate and the inner wall of the pump housing and the outer wall of the drive shaft, and the storage cavity and the working cavity are connected through the silicone oil inlet pipe.

[0020] In the above implementation process, the silicone oil with strong viscosity can bond the driving plate and the driven plate, so that the driven plate twists following the driving plate.

[0021] In a specific embodiment, oil return pipelines communicating with the oil storage cavity and the working cavity are further connected to both sides of the inner wall of the pump housing, and one-way valves are installed on the oil return pipelines.

[0022] In the above implementation process, under the action of the high-speed rotation of the drive shaft, the silicone oil in the working cavity will be thrown outwards under the action of centrifugal force, push open the one-way valve and re-enter the oil storage cavity through the oil return pipeline for recycling. When the silicone oil circulates, it can transfer heat to the clutch housing and be cooled, so as to avoid the excessive temperature of the silicone oil during operation.

[0023] In a specific embodiment, a temperature control switch located on the inner wall of the oil storage cavity is further installed on the inner wall of the pump housing, and an oil injection channel is connected to the pump housing. A plug is connected to the opening of the oil injection channel.

[0024] In the above implementation process, the temperature control switch in the prior art can sense the temperature of the silicone oil in the oil storage cavity and control the opening and closing of the solenoid valve, which is beneficial to more precisely control the speed of the open impeller according to the size of the temperature set value, so as to achieve the purpose of stepless speed regulation.

[0040] Please refer to Figures 1-5 , this application provides an open impeller type electronically controlled silicone oil clutch water pump with a flow guiding function, including a pump housing installation assembly 10 and an impeller transmission assembly 20.

[0041] Among them, the pump housing installation assembly 10 facilitates the quick disassembly and assembly of the pump housing 130 and the external engine housing without the aid of external tools, changing the disadvantage of inconvenient disassembly and assembly using screws or bolts in the past; the impeller transmission assembly 20 can infinitely adjust the speed, and at the same time can reduce the impact and eddy current formed by the coolant at the original right-angle outlet of the pump housing 130, reduce the water outlet resistance, reduce the impact loss, improve the hydraulic efficiency of the water pump, reduce the power consumption of the water pump, and improve the fuel economy of the engine.

[0042] Please refer to Figure 1 , 2, 3, the pump housing installation assembly 10 includes insertion rods 120 and a pump housing 130. There are two insertion rods 120. Cross-shaped slots 140 are provided on both sides of the two pump housings 130 close to the insertion rods 120. The insertion rods 120 are inserted into the corresponding cross-shaped slots 140. Clamping frames 150 are also inserted into the cross-shaped slots 140. Insertion holes are provided on the insertion rods 120. The two clamping frames 150 are respectively inserted and fixed to the two insertion rods 120 through the corresponding insertion holes. Spring pairs 160 are connected to the clamping frames 150, and the outer ends of the spring pairs 160 are fixedly connected to the pump housing 130.

[0043] Please refer to Figure 1 , 4 , 5, the impeller drive assembly 20 includes a driving member 210, a driven member 220, and an open impeller 230. The driving member 210 is rotatably connected to the inner cavity of the pump housing 130. The driving member 210 is movably engaged with the driven member 220. The open impeller 230 is connected to the outer end of the driven member 220, and the open impeller 230 rotates through the cooperation between the driving member 210 and the driven member 220. A guide plate 180 is also provided at the coolant output end of the pump housing 130. Among them, the outlet of a traditional water pump is often in a right-angled shape, which will generate relatively large impact and eddy currents, causing impact losses. Especially when the coolant reaches the outlet after pressure expansion, the kinetic energy is the largest, and this kind of impact loss is particularly obvious, resulting in low water pump efficiency, more engine power consumption, and insufficient energy conservation and environmental protection. By using the guide plate 180, the impact and eddy currents formed by the coolant at the original outlet can be reduced, the outlet resistance can be lowered, the impact loss can be reduced, the hydraulic efficiency of the water pump can be improved, the power consumption of the water pump can be reduced, and the fuel economy of the engine can be improved.

[0044] In some specific implementation schemes, the driving member 210 includes a drive shaft 211, a bearing 212, and a driving plate 213. The inner and outer rings of the bearing 212 are respectively in interference fit with the drive shaft 211 and the inner cavity of the pump housing 130. Among them, the setting of the bearing 212 enables the drive shaft 211 to rotate with the output end of an external engine, and the pump housing 130 will not rotate together during rotation. The drive shaft 211 is fixed to the output shaft of the external engine. The driving plate 213 is connected to one end of the drive shaft 211. The outer wall of the driving plate 213 is provided with an external gear ring. Among them, the connection method between the other end of the drive shaft 211 and the output end of the engine is prior art and will not be elaborated here. The driving plate 213 is fixed to one end of the drive shaft 211 by screws. Driven by the rotation of the drive shaft 211, the driving plate 213 and the external gear ring will also rotate at the same speed.

[0045] In some specific embodiments, the follower 220 includes a follower shaft 221, a follower plate 222, and a pair of moving rings 223 and stationary rings 224. The follower shaft 221 penetrates through the inner cavity of the pump housing 130. Among them, the two moving rings 223 are respectively connected to both sides of the outer wall of the follower shaft 221, and the two stationary rings 224 are respectively fixedly connected to both sides of the inner wall of the pump housing 130. Sealing rings that fit with the corresponding moving rings 223 are adhesively fixed to the two stationary rings 224, and the two stationary rings 224 are respectively connected to the moving rings 223 in an actively sealed manner through the corresponding sealing rings. The connection methods of the stationary rings 224 and the moving rings 223 to the pump housing 130 and the follower shaft 221 respectively are prior arts. By using the cooperation of the stationary rings 224, the moving rings 223, and the sealing rings, the silicone oil in the oil storage cavity 240 can be reduced from mixing outwardly with the coolant, thereby indirectly increasing the sealing performance of the oil storage cavity 240. Among them, the follower plate 222 is fixedly connected to one end of the follower shaft 221. A circular concave cavity is provided on the side of the follower plate 222 close to the driving plate 213. The inner wall of the circular concave cavity is provided with an internal gear ring, and the driving plate 213 extends into the circular concave cavity. A pair of silicone oil inlet pipes 225 are communicated with the follower plate 222, and electromagnetic valves 226 are also installed on the two silicone oil inlet pipes 225. Among them, the electromagnetic valves 226 can be used to control the opening and closing of the silicone oil inlet pipes 225, thereby facilitating the control of the silicone oil in the oil storage cavity 240 to enter the working cavity 250.

[0046] In some specific embodiments, a storage cavity 240 is formed between the side of the follower plate 222 away from the driving plate 213 and the inner wall of the pump housing 130 and the outer wall of the follower shaft 221. A working cavity 250 is formed between the side of the follower plate 222 close to the driving plate 213 and the inner wall of the pump housing 130 and the outer wall of the driving shaft 211. The storage cavity 240 and the working cavity 250 are communicated through the silicone oil inlet pipes 225. Among them, the silicone oil with strong viscosity can be used to bond the driving plate 213 and the follower plate 222, so that the follower plate 222 twists following the driving plate 213. Both sides of the inner wall of the pump housing 130 are also communicated with an oil return pipe 170 that is communicated with the storage cavity 240 and the working cavity 250. Check valves 110 are also installed on the oil return pipes 170. Among them, under the action of the high-speed rotation of the driving shaft 211, the silicone oil in the working cavity 250 will be thrown outwards under the action of centrifugal force, push open the check valves 110 and re-enter the storage cavity 240 through the oil return pipes 170 for recycling. When the silicone oil circulates, it can transfer heat to the clutch housing to be cooled, so as to avoid the silicone oil temperature being too high during operation. A temperature control switch 190 located on the inner wall of the storage cavity 240 is also installed on the inner wall of the pump housing 130. An oil injection channel is also communicated with the pump housing 130, and a plug is connected to the opening of the oil injection channel. Among them, the temperature control switch 190 in the prior art can sense the temperature of the silicone oil in the storage cavity 240 and control the opening and closing of the electromagnetic valves 226, thereby facilitating more precise control of the rotation speed of the open impeller 230 according to the size of the temperature set value, achieving the purpose of stepless speed regulation.

[0047] The working principle of the open impeller type electronically controlled silicone oil clutch water pump with diversion function is as follows: when in use, one end of the plug-in rod 120 is welded to the external engine housing in advance. When the pump housing 130 needs to be installed with the external engine housing, two clamping frames 150 are pulled outward, and the two plug-in rods 120 are plugged into the corresponding cross-shaped slots 140, and then the two clamping frames 150 are loosened. The tightening force of the spring 160 can stably plug the two clamping frames 150 into the corresponding insertion holes, which indirectly improves the efficiency of disassembling and assembling the pump housing 130 and the external engine housing. When removing the pump housing 130, it is only necessary to pull out the two clamping frames 150 and disengage the two plug-in rods 120 from the corresponding cross-shaped clamping grooves 140, and then use the flange to connect and fix the drive shaft 211 to the external engine output end. When the engine is just started, the silicone oil temperature in the oil storage chamber 240 sensed by the temperature control switch 190 does not reach the set value. At this time, the solenoid valve 226 will not be started, so that the silicone oil in the oil storage chamber 240 flows into the working chamber 250, so that the drive shaft 211 is in an idling state. When the engine speed increases, the pump housing 130 The temperature inside the pump housing 130 will also gradually rise. When the silicone oil temperature in the oil storage chamber 240 sensed by the temperature control switch 190 reaches the set value, the solenoid valve 226 will be controlled to open so that the silicone oil in the oil storage chamber 240 flows into the working chamber 250 through the silicone oil inlet pipe 225. At this time, the viscous silicone oil will flow to the gap between the driven plate 222 and the active plate 213. The torque of the active plate 213 is transmitted to the driven plate 222. The driven plate 222 indirectly drives the open impeller 230 to rotate at a high speed through the driven shaft 221. A curved guide plate 180 is also provided at the coolant output end of the turbine channel of the pump housing 130. The coolant driven by the centrifugal force of the open impeller 230 rotates. The pressure gradually expands along the vortex chamber flow channel on the pump housing 130 and bursts out toward the guide plate 180 set at the water outlet. The guide plate 180 can reduce the impact and vortex formed at the original outlet of the coolant, reduce impact loss, improve the hydraulic efficiency of the water pump, reduce the power consumption of the water pump, and improve the fuel economy of the engine. At the same time, under the high-speed rotation of the drive shaft 211, the silicone oil in the working chamber 250 will be thrown outward under the action of centrifugal force, push open the one-way valve 110 and re-enter the oil storage chamber 240 through the return oil pipe 170 for recycling. The silicone oil can transfer heat to the clutch housing during circulation and be cooled to avoid excessive temperature of the silicone oil during operation.

[0048] It should be noted that the specific models and specifications of the static ring 224, the dynamic ring 223, the one-way valve 110, the spring 160, the temperature control switch 190, and the solenoid valve 226 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0049] The power supply and principle of the temperature control switch 190 and the solenoid valve 226 are clear to those skilled in the art and will not be described in detail herein.

[0050] The above are only embodiments of the present application and are not used to limit the protection scope of the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application. It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0051] As mentioned above, this is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present application can easily think of changes or replacements, which should all be covered by the protection scope of the present application.
