Description

Technical Field

[0001] This utility model relates to a water tank lubricant cooling pipe, belonging to the technical field of cooling pipes. Background Technology

[0002] Currently, the lubricant control method involves the lubricant entering the cooling water of the heat exchanger for cooling. Since the lubricant cooling heat exchanger is controlled one-to-one, and the cooling water source is industrial water, which is not very clean and requires regular maintenance and cleaning, a single heat exchanger cannot be maintained online. In particular, the frequency of maintenance increases in hot weather, and all machine tools in this system must be shut down during maintenance, resulting in a loss of production capacity.

[0003] The shortcomings of existing technology are:

[0004] 1. When the lubricant temperature is too high, the heat exchanger cannot be cleaned online;

[0005] 2. The temperature of the lubricant cannot be effectively controlled;

[0006] 3. The machine tool must be stopped for cleaning the heat exchanger, which results in a loss of production capacity. Utility Model Content

[0007] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a water tank lubricant cooling pipe. By connecting the lubricant pipes online and welding valves to the pipes to control the lubricant in series, when the lubricant temperature in the control system is higher than the process range and the heat exchanger needs to be cleaned, the valve is opened to allow the lubricant to be used in conjunction with the adjacent heat exchanger. After use, the lubricant temperature is controlled, reducing the loss of production capacity.

[0008] To achieve the above objectives, this utility model employs the following technical solution:

[0009] In a first aspect, this utility model provides a water tank lubricant cooling pipe, comprising:

[0010] At least two liquid inlet pipes are provided, each of which is modified into a three-way structure. One channel serves as the original liquid inlet channel, while of the other two channels, one channel is directly connected to the corresponding heat exchanger, and the other channel is connected to the corresponding channel of the adjacent liquid inlet pipe, forming a series structure.

[0011] A turbine butterfly valve, wherein the turbine butterfly valve is disposed in the passage between adjacent liquid inlet pipes;

[0012] At least two heat exchangers, each connected to its corresponding inlet pipe;

[0013] There are at least two liquid outlet pipes, each of which is connected to its corresponding heat exchanger.

[0014] Furthermore, the channels between adjacent liquid inlet pipes are connected by welding.

[0015] Furthermore, rubber flexible joints are provided at the connection points between the heat exchanger and the inlet and outlet pipes.

[0016] Furthermore, a pressure sensor is installed at the inlet end of the heat exchanger.

[0017] Furthermore, the outlet of the heat exchanger is equipped with a temperature sensor.

[0018] Furthermore, the outlet of the heat exchanger is also equipped with an alarm, which is communicatively connected to a temperature sensor.

[0019] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0020] This utility model provides a water tank lubricant cooling pipe. By connecting the lubricant pipes online and welding valves on the pipes to control the lubricant in series, when the lubricant temperature in the control system is higher than the process range and the heat exchanger needs to be cleaned, the valve is opened to allow the lubricant to be used in conjunction with the adjacent heat exchanger. After use, the lubricant temperature is controlled, reducing the loss of production capacity. Attached Figure Description

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0026] This embodiment describes a water tank lubricant cooling pipe, including:

[0027] At least two liquid inlet pipes 1, each of which is modified into a three-way structure, one of which serves as the original liquid inlet channel, and of the other two channels, one channel is directly connected to the corresponding heat exchanger 3, and the other channel is connected to the corresponding channel of the adjacent liquid inlet pipe 1 by welding to form a series structure;

[0028] The turbine butterfly valve 2, located in the middle channel of each three-way structure, is used to control whether the lubricant enters the adjacent heat exchanger 3 through the channel.

[0029] At least two heat exchangers 3, each heat exchanger receiving lubricant for cooling through its corresponding inlet pipe 1;

[0030] The liquid outlet pipe 4 is used to discharge the lubricant that has been cooled by the heat exchanger 3 from the system.

[0031] When maintenance is required on a heat exchanger 3 or its lubricant temperature is detected to exceed the standard, the inlet valve corresponding to the heat exchanger 3 is closed, and the turbine butterfly valve 2 on the inlet pipe 1 adjacent to the heat exchanger 3 is opened at the same time. This allows the lubricant to bypass the heat exchanger 3 that needs maintenance and directly enter the adjacent heat exchanger 3 for cooling, thereby achieving online maintenance and cleaning without stopping the machine tool.

[0032] The turbine butterfly valve 2 has a quick-opening and closing function to ensure the smoothness and stability of the lubricant when switching heat exchangers 3. The number of heat exchangers 3 can be increased or decreased according to actual needs to adapt to different scale machine tool lubrication systems. The inlet pipe 1, turbine butterfly valve 2, heat exchangers 3, and outlet pipe 4 are all made of corrosion-resistant and high-temperature-resistant materials to ensure long-term stable operation of the system. Rubber flexible joints are also provided at the connection points of the pipes to alleviate resonance problems between pipes and allow for free buffering between pipes. A pressure sensor is installed at the inlet end of the heat exchanger 3 to monitor and control the inlet and outlet pressure of the lubricant. A temperature sensor is installed at the outlet of the heat exchanger 3 to control the outlet temperature of the lubricant, facilitating the control of the physical and chemical properties of the lubricant. An alarm is also installed to alert the lubricant maintenance personnel to make timely adjustments when the temperature exceeds the internal control standard.

[0033] Working principle: such as Figure 1 As shown, multiple straight-through inlet pipes 1 are replaced with tees, using two pipes welded together, with a turbine butterfly valve 2 controlling the connection. When maintenance of heat exchanger 3 is required according to the maintenance plan or when the lubricant temperature exceeds the standard, the inlet valve of the heat exchanger 3 to be cleaned is closed, and the series-connected turbine butterfly valve 2 is opened, allowing lubricant to enter the adjacent heat exchanger 3 for lubricant cooling. After the improvement, maintenance and cleaning can be performed online without stopping the machine tool.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
