Description

Technical Field

[0001] This invention relates to the field of water pumping equipment technology, and in particular to a water-cooled water pump silencer. Background Technology

[0002] In the field of water pumping equipment technology, water pumps are key equipment widely used in various fields such as agricultural irrigation, industrial water supply, and urban drainage. A water pump consists of a pump and an engine. The engine drives the pump, which pumps and pressurizes water before outputting it. Currently, water pumps generate excessive noise during operation. To reduce noise pollution, silencers are used to reduce noise levels and prevent excessive noise.

[0003] However, when the water pump operates for a long time, the muffler will become red and hot due to the high temperature of the exhaust gas from the engine, resulting in a decrease in noise reduction capability. The exhaust gas volume is large, and the kinetic energy when passing through the muffler is large, which will generate more noise. Summary of the Invention

[0004] The purpose of this invention is to provide a water-cooled water pump muffler, which solves the problem that existing water pumps, when working for a long time, will cause the muffler to become red-hot due to the high temperature of the exhaust gas from the engine, resulting in a decrease in noise reduction capability. Additionally, the large volume of exhaust gas and the large kinetic energy it generates when passing through the muffler will also cause significant noise.

[0005] To achieve the above objectives, the present invention provides a water-cooled water pump muffler, comprising a mounting bracket, a water pump assembly, and an engine, wherein the water pump assembly and the engine are both disposed within the mounting bracket, and the engine is connected to the water pump assembly.

[0006] The engine includes a left housing, a right housing, a cylinder head, a cylinder head cover, spark plugs, a muffler assembly, a start / stop assembly, an intake manifold, a throttle valve body assembly, an air filter assembly, and a cooling assembly. The right housing is connected to the left housing. The cylinder head is located on the front mating surface of the right housing and the left housing. The cylinder head cover is fixedly connected to the cylinder head. The spark plug is located on the top of the cylinder head cover. The muffler assembly is connected to the left side of the cylinder head. The start / stop assembly is connected to the left housing. The intake manifold is connected to the mating surface of the left housing and the right housing. The throttle valve body assembly is connected to the intake manifold. The air filter assembly is connected to the throttle valve body assembly and is located outside the throttle valve body assembly. The cooling assembly is connected to the water pump assembly, the cylinder head cover, and the muffler assembly.

[0007] The water pump assembly includes a water pump inlet cover, a water pump body, and a water pump outlet cover. The water pump outlet cover is connected to the right housing and has an outlet, a cooling water return hole, and a cooling water outflow hole. The water pump body is connected to the water pump outlet cover, and the water pump inlet cover is connected to the water pump body. The water pump inlet cover has an inlet.

[0008] The cooling assembly includes two first cooling water pipes, a first water pipe connector, a second water pipe connector, a first tee connector, two second cooling water pipes, a third water pipe connector, a fourth water pipe connector, and a second tee connector. The first water pipe connector is connected to the cooling water outlet, and the fourth water pipe connector is connected to the cooling water return outlet. The second and third water pipe connectors are both connected to the muffler assembly. The first tee connector is connected to the cylinder head, and the second tee connector is connected to the cylinder head cover. One of the first cooling water pipes has its two ends connected to the first water pipe connector and the first tee connector, respectively. The other first cooling water pipe has its two ends connected to the first tee connector and the second water pipe connector, respectively. One of the second cooling water pipes has its two ends connected to the third water pipe connector and the second tee connector, respectively. The other second cooling water pipe has its two ends connected to the second tee connector and the fourth water pipe connector, respectively.

[0009] The opening and closing assembly includes a starter motor, a magneto base, a magneto cover, and a manual starter. The starter motor is connected to the left housing and is located on the upper side of the left housing. The magneto base is connected to the left housing and is located on the left side of the left housing. The magneto cover is connected to the magneto base, and the manual starter is disposed on the magneto cover.

[0010] The mounting bracket includes a frame, a left clamp, a right clamp, an ignition coil assembly, and a control box. The left and right clamps are both fixedly connected to the frame and are located within the frame. The ignition coil assembly is fixedly installed within the frame. The control box is fixedly connected to the frame and is located on the outer wall of the frame. The water pump inlet cover is fixedly connected to the right clamp, and the left clamp is fixedly connected to the hand-operated starter.

[0011] The mounting bracket also includes a display screen, which is fixedly connected to the mounting bracket and located above the mounting bracket.

[0012] This invention discloses a water-cooled water pump muffler. By integrating the mounting bracket, the water pump assembly, and the engine, a compact and efficient water pumping system is formed. The engine drives the water pump assembly to operate, pumping and pressurizing water for output. When the water pump assembly is operating, low-pressure water flows through it, resulting in high-pressure water. This ensures a continuous supply of cooling water from the water pump assembly into the cooling assembly, and then into the cooling water channels after the cylinder head and the muffler assembly. After passing through the cooling water channels, the water pressure decreases, and the water then flows back into the water pump assembly, forming a closed-loop cooling circulation system. In this method, the water pumped up by the pump itself during operation... Water is used to cool the cylinder head and muffler assembly of the engine, preventing damage to the hot components of the cylinder head due to excessive operating temperature. On the other hand, it lowers the operating temperature of the muffler assembly, preventing it from becoming red-hot due to the high-temperature exhaust gas from the engine, thus avoiding burns to users. Additionally, it indirectly cools the exhaust gas, lowering its temperature and volume. As the exhaust gas passes through the muffler assembly 108, its kinetic energy decreases, and the noise generated is also reduced. By employing the above methods, the water pump and muffler achieve self-cooling, lowering the operating temperature of the muffler, cooling the exhaust gas, reducing its volume, and decreasing its kinetic energy as it passes through the muffler, significantly reducing noise and ensuring the muffler's noise reduction capability.

Detailed Implementation

[0022] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] Please see Figures 1 to 7 The present invention provides a water-cooled water pump muffler: including a mounting bracket, a water pump assembly and an engine, wherein the water pump assembly and the engine are both disposed in the mounting bracket and the engine is connected to the water pump assembly;

[0024] The engine includes a left housing 103, a right housing 104, a cylinder head 105, a cylinder head cover 106, a spark plug 107, a muffler assembly 108, an opening and closing assembly, an intake manifold 109, a throttle valve body assembly 110, an air filter assembly 111, and a cooling assembly. The right housing 104 is connected to the left housing 103. The cylinder head 105 is disposed on the front mating surface of the right housing 104 and the left housing 103. The cylinder head cover 106 is fixedly connected to the cylinder head 105. The spark plug 107 is disposed on the cylinder head cover 106. At the top, the muffler assembly 108 is connected to the left side of the cylinder head 105, the opening and closing assembly is connected to the left housing 103, the intake pipe 109 is connected to the mating surface of the left housing 103 and the right housing 104, the throttle valve body assembly 110 is connected to the intake pipe 109, the air filter assembly 111 is connected to the throttle valve body assembly 110 and is located outside the throttle valve body assembly 110, and the cooling assembly is connected to the water pump assembly, the cylinder head cover 106 and the muffler assembly 108 respectively.

[0025] In this embodiment, by integrating the mounting bracket, the water pump assembly, and the engine, a compact and efficient water pumping system is formed. The engine drives the water pump assembly to operate, and the water pump assembly pumps and pressurizes water for output. When the water pump assembly is operating, low-pressure water flows through the water pump assembly to produce high-pressure water, ensuring a continuous supply of cooling water from the water pump assembly into the cooling assembly. The water then enters the cooling water passages after the cylinder head 105 and the muffler assembly 108. After passing through the cooling water passages, the water pressure decreases, and the water then flows back into the water pump assembly, forming a closed-loop cooling circulation system. In this method, the engine is cooled by the water pumped up by the water pump itself during operation. The cylinder head 105 and the muffler assembly 108 of the engine are self-cooled, preventing the cylinder head 105 from being damaged by excessively high operating temperatures. On the other hand, the operating temperature of the muffler assembly 108 is reduced to prevent it from becoming red-hot due to the high-temperature exhaust gas from the engine, thus avoiding burns to users. Additionally, the exhaust gas is indirectly cooled, resulting in a lower exhaust gas temperature and volume. As the exhaust gas passes through the muffler assembly 108, its kinetic energy decreases, and the noise generated is also reduced. By employing the above methods, the water pump and muffler achieve self-cooling, reducing the operating temperature of the muffler and cooling the exhaust gas, thus reducing its volume and kinetic energy as it passes through the muffler, significantly reducing noise and ensuring the muffler's noise reduction capability.

[0026] Further, the water pump assembly includes a water pump inlet cover 112, a water pump body 113, and a water pump outlet cover 114. The water pump outlet cover 114 is connected to the right housing 104. The water pump outlet cover 114 has an outlet 132, a cooling water return hole 133, and a cooling water outflow hole 134. The water pump body 113 is connected to the water pump outlet cover 114, and the water pump inlet cover 112 is connected to the water pump body 113. The water inlet cover 112 has a water inlet 102; the cooling assembly includes two first cooling water pipes 115, a first water pipe connector 116, a second water pipe connector 117, a first tee connector 118, two second cooling water pipes 119, a third water pipe connector 120, a fourth water pipe connector 121, and a second tee connector 122. The first water pipe connector 116 is connected to the cooling water outlet hole 134, and the fourth water pipe connector 129... 1. Connected to the cooling water return hole 133, the second water pipe connector 117 and the third water pipe connector 120 are both connected to the muffler assembly 108, the first tee connector 118 is connected to the cylinder head 105, and the second tee connector 122 is connected to the cylinder head cover 106. One of the first cooling water pipes 115 has its two ends connected to the first water pipe connector 116 and the first tee connector 118, respectively. Another of the first cooling water pipes 115 has its two ends connected to the first tee connector 118 and the second water pipe connector 117, respectively. One of the second cooling water pipes 119 has its two ends connected to the third water pipe connector 120 and the second tee connector 122, respectively. Another of the second cooling water pipes 119 has its two ends connected to the second tee connector 122 and the fourth water pipe connector 121, respectively.

[0027] In this embodiment, the water pump inlet 102 is connected to a water source via a water pipe, and the water pump outlet 132 delivers water to other locations requiring water via a connecting water pipe. The engine drives the water pump assembly to pump water. Water enters the water pump body 113 through the water pump inlet cover 112. After being pressurized by the operation of the water pump body 113, the water is output from the water pump outlet 132 of the water pump outlet cover 114. Most of the pressurized water flows out through the water pump outlet 132, while a small amount of pressurized water enters the first cooling water pipe 115 through the first water pipe connector 116 at the cooling water outlet hole 134 on the water pump outlet cover 114. After reaching the first three-way connector 118, some water enters the cooling water channel inside the cylinder head 105 to cool the cylinder head 105. Then, it passes through the cooling water channel on the cylinder head cover 106 and is discharged from the engine. The second three-way connector 122 on the cylinder head cover 106 enters the return pipe; another part of the water flows through the first cooling water pipe 115 to the second water pipe connector, enters the cooling chamber of the muffler assembly 108, cools the outer shell of the muffler assembly 108, and then flows out through the water pipe connector above the muffler assembly 108, enters the return second cooling water pipe 119 and reaches the second three-way connector 122 on the cylinder head cover 106. After the two water flows converge at the second three-way connector 122, they flow through the second cooling water pipe 119 to the fourth water pipe connector 121 on the water pump inlet cover 112, return to the water pump inlet cover 112 through the cooling water return hole 133 of the water pump inlet cover 112, and then enter the inlet 102, achieving the circulation of cooling water and realizing the self-cooling of the water pump.

[0029] In this embodiment, the opening and closing assembly increases the flexibility and reliability of the device. The starter motor 123 is located on the upper side of the left housing 103 for easy operation and maintenance. The magneto mount 124 and the magneto cover 125 protect the magneto from external environmental influences, extending its service life. The hand-operated starter 126 facilitates starting in environments without power, improving the device's applicability and portability.

[0030] Furthermore, the mounting bracket includes a frame 101, a left clamping plate 127, a right clamping plate 128, an ignition coil assembly 129, and a control box 130.
