Abstract

This utility model discloses a self-circulating cooling water system structure, including a suction pipe, a connecting pipe at the top of the suction pipe, and a suction valve at the other end of the connecting pipe connected to the suction end of a high-pressure pump. The inner cavity of the connecting pipe is provided with a suction valve that controls the flow rate of the liquid entering and its on / off state. A connecting hole is provided at the bottom of the suction pipe and at a position corresponding to the connecting pipe. A return water connector is connected to the inner cavity of the connecting hole through a detachable component. A return water pipe is connected to the top of the return water connector. The other end of the return water pipe extends upward to below the suction end of the suction valve.

One end of the return water pipe is located below this negative pressure area, and the return water pipe is connected to an external circulating water pipe through the return water connector. Under the action of negative pressure, water in the external cooling water is drawn into the return water pipe, thereby making the cooling water flow and forming a cooling cycle.

Description

Technical Field

[0001] This utility model relates to the technical field of self-circulating cooling water system structure, specifically a self-circulating cooling water system structure. Background Technology

[0002] During the operation of a high-pressure pump, heat is generated in various parts of the pump body due to friction and the action of the medium. Sustained high temperature will reduce the mechanical properties of the pump body material, such as reduced strength and hardness, and may even cause deformation and cracking. The cooling system can control the pump body temperature, prevent the material from being damaged due to overheating, extend the service life of the pump body, and maintain its structural integrity.

[0003] In existing high-pressure pumps, cooling water circulation relies mainly on pressure difference. However, this pressure difference-dependent cooling water circulation method has obvious defects. When the cooling water pressure difference is insufficient, the cooling water cannot circulate, which may lead to the heat generated by the high-pressure pump being difficult to dissipate effectively, thereby affecting the pump's performance, shortening its service life, and even causing pump failure, affecting the normal operation of the entire production system. Utility Model Content

[0004] The purpose of this invention is to provide a self-circulating cooling water system structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A self-circulating cooling water system structure includes a suction pipe, the top of which is connected to a connecting pipe, and the other end of which is connected to the suction end of a high-pressure pump. The inner cavity of the connecting pipe is provided with a suction valve that controls the flow rate of liquid entering and its on / off state. The bottom of the suction pipe and corresponding to the connecting pipe are provided with a connecting hole. The inner cavity of the connecting hole is connected to a return water connector via a detachable component. The top of the return water connector is connected to a return water pipe, and the other end of the return water pipe extends upward to below the suction end of the suction valve.

[0007] As a preferred technical solution, the detachable component includes an external threaded ring fixedly sleeved on the upper surface of the return water connector, and the upper end of the return water connector is threadedly connected to the inner cavity of the connection hole through the external threaded ring.

[0008] As a preferred technical solution, the surface of the external threaded ring is coated with an anaerobic adhesive layer.

[0009] As a preferred technical solution, a rubber ring is fixedly fitted on the lower end surface of the return water connector.

[0010] As a preferred technical solution, the return water pipe is a stainless steel pipe.

[0011] As a preferred technical solution, the inner wall of the suction tube is coated with an anti-rust layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, through the setting of the return water pipe, creates a negative pressure area below the suction end of the suction valve when the suction valve draws water. One end of the return water pipe is located below this negative pressure area, and the return water pipe is connected to the external circulating water pipe through a return water connector. Under the action of negative pressure, water in the external cooling water is drawn into the return water pipe, thereby causing the cooling water to flow and forming a cooling cycle.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1This embodiment provides a self-circulating cooling water system structure, including a suction pipe 100, with a connecting pipe 107 connected to the top of the suction pipe 100. The other end of the connecting pipe 107 is connected to the suction end of a high-pressure pump. A suction valve 103 is provided inside the connecting pipe 107 to control the flow rate and on / off state of the liquid entering. A connecting hole 105 is provided at the bottom of the suction pipe 100, corresponding to the connecting pipe 107. A return water connector 102 is connected to the inner cavity of the connecting hole 105 via a detachable component. A return water pipe 101 is connected to the top of the return water connector 102. The other end extends upward to below the suction end of the suction valve 103. Through the setting of the return water pipe 101, when the suction valve 103 draws water, a negative pressure area is formed below the suction end of the suction valve 103. One end of the return water pipe 101 is located below this negative pressure area, and the return water pipe 101 is connected to the external circulating water pipe through the return water connector 102. Under the action of negative pressure, water in the external cooling water is drawn into the return water pipe 101, thereby making the cooling water flow to form a cooling cycle, which greatly improves the heat dissipation effect of the high-pressure pump, thereby ensuring the performance of the pump and maintaining the normal operation of the production system.

[0019] The detachable component includes an external threaded ring 104 fixedly sleeved on the upper surface of the return water connector 102. The upper end of the return water connector 102 is threadedly connected to the inner cavity of the connection hole 105 through the external threaded ring 104. With the setting of the detachable component, the return water connector 102 is threadedly engaged with the connection hole 105 of the suction pipe 100 through the external threaded ring 104, which allows the return water connector 102 to be quickly disassembled, facilitating the cleaning of pipe blockages, replacement of parts, or maintenance of the suction valve 103, thereby reducing downtime.

[0020] The surface of the external threaded ring 104 is coated with an anaerobic adhesive layer. After the anaerobic adhesive layer cures in the thread gap, it enhances the connection sealing and prevents the threads from loosening due to vibration or pressure fluctuations. It is especially suitable for the high-frequency vibration environment of high-pressure pumps.

[0021] Among them, anaerobic adhesives should preferably use industrial-grade methacrylate products (such as Loctite 510 series) to ensure the sealing and vibration resistance of threaded connections.

[0022] Among them, a rubber ring 108 is fixedly sleeved on the lower end surface of the return water connector 102. The rubber ring 108 can effectively prevent cooling water from leaking from the gap between the return water connector 102 and the cooling water pipe when connecting the cooling water pipe.

[0023] Among them, the return water pipe 101 is made of stainless steel, which can not only withstand the corrosion of cooling water, avoid rust and blockage of the pipe, and extend the service life of the system, but also withstand the pressure fluctuations when the high-pressure pump is running, and is not easily deformed or broken, thus ensuring the stability of the circulation path.

[0024] The inner wall of the suction pipe 100 is coated with an anti-rust layer 106. The anti-rust layer 106 protects the inner wall of the suction pipe 100 from corrosion by cooling water, especially for high-pressure pumps that have been used for a long time, reducing the risk of pipe perforation or peeling.

[0025] Among them, the anti-rust layer 106 is one or more of the following: epoxy zinc-rich coating, polyurethane coating, and ceramic coating.

[0026] Working principle;

[0027] First, the circulating water pipe is sleeved on the surface of the rubber ring 108. When the suction valve 103 draws water, a negative pressure area is formed below the suction end of the suction valve 103. One end of the return water pipe 101 is located below this negative pressure area, and the return water pipe 101 is connected to the external circulating water pipe through the return water connector 102. Under the action of negative pressure, water in the external cooling water is drawn into the return water pipe 101.

[0028] As the high-pressure pump continues to run, the suction valve 103 continuously draws in water, and the water in the return pipe 101 is continuously drawn in and replenished into the cooling cycle of the high-pressure pump. Together with the fresh cooling water entering from the suction pipe 100, it participates in the cooling process of the high-pressure pump, and then is discharged through the drainage channel of the high-pressure pump, completing the circulation of cooling water, thereby realizing the cooling function of the high-pressure pump.

[0029] Furthermore, the external threaded ring 104 is threadedly connected to the connecting hole 105. The anaerobic adhesive layer applied to the surface of the external threaded ring 104 helps to enhance the stability of the connection. The rubber ring 108 is fitted at the lower end of the return water connector 102 to provide a seal and prevent water leakage. When it is necessary to repair the return water pipe 101, the return water connector 102 can be disassembled simply by rotating it, which is very convenient and quick.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
