Description

Technical Field

[0001] This utility model relates to the field of lubrication equipment technology, and in particular to a lubrication system. Background Technology

[0002] Medium and heavy plate rolling mills are key equipment in metal rolling production, and a sufficient supply of lubricating oil to all moving parts of the mill is crucial for its safe operation. The mill's lubrication system has numerous lubrication points, complex and disorganized branch pipelines, and most lack metering. Existing lubrication systems suffer from insufficient monitoring capabilities and an inability to regulate lubricating oil flow, failing to provide real-time feedback on whether the lubricating oil flow in each branch pipeline is normal and whether the equipment is effectively lubricated, thus posing certain safety risks to the mill's operation. During operation, only a single main control valve manages the process. When lubrication is needed for a single area, other distributors connected to the same pipeline also simultaneously release oil, causing lubrication to be released from unnecessary points and resulting in wasted lubricating oil.

[0003] Meanwhile, existing high-precision lubrication systems often require a larger volume to achieve higher precision requirements, but the installation space of medium and heavy plate rolling mills is limited, making it impossible to meet the installation conditions of high-precision lubrication systems. Utility Model Content

[0004] The technical problem to be solved by this utility model is: how to solve the problem of miniaturized design and installation of high-precision lubrication systems.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] This utility model provides a lubrication system, including:

[0007] The flow control box contains a main flow pipe and several branch flow pipes. The branch flow pipes include main branch pipes and bypass branch pipes. The lower ends of the main branch pipes and bypass branch pipes are connected, and the upper ends are respectively connected to the main flow pipe.

[0008] The main branch pipe is equipped with an inlet regulating valve, a filter, a flow sensor and an outlet regulating valve, and the bypass branch pipe is equipped with a bypass regulating valve.

[0009] The flow totalizer box is connected to the flow control box and includes several totalizers.

[0010] The main flow pipe is connected to an external lubricant storage unit via a flange.

[0011] The filter is a Y-type filter used to remove impurities from the lubricating fluid.

[0012] The lower end of the branch main pipe is equipped with a quick connector, which connects to a hose to deliver lubricant to the part to be lubricated.

[0013] The flow branch pipe is equipped with a three-port connector, which includes a first interface, a second interface, and a third interface. The first interface is connected to the outlet regulating valve, the second interface is connected to the bypass regulating valve, and the third interface is connected to the quick connector.

[0014] The bypass regulating valve is a ball valve, used to regulate the flow rate of the bypass branch pipe.

[0015] The totalizer is equipped with a display unit and a data processing unit. The data processing unit receives data collected by the flow sensor and calculates the flow information on the corresponding main branch pipe. The display unit displays the flow information in real time.

[0016] The flow sensor and the totalizer are connected one-to-one via cables.

[0017] This invention fully considers the limited installation space inside the equipment and the large number of circuits requiring lubrication. It adopts a split-type flow meter design, with separate flow control boxes and flow totalizer boxes. The flow totalizer box can be installed externally and connected via cables, greatly reducing the system's installation volume and saving space. Each flow totalizer corresponds to a lubrication branch, enabling real-time accurate detection and management. Concentrating all flow totalizers in a single box facilitates observation and unified management. A bypass regulating valve ensures that offline maintenance of the flow sensor does not affect normal lubrication, allowing for maintenance without shutting down the equipment and improving its effective operating rate.

[0023] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0024] Example 1

[0025] refer to Figures 1 to 3 As shown, a lubrication system includes:

[0026] The flow control box includes a box body 1, a main flow pipe 2, and several branch flow pipes. All branch flow pipes are connected to the main flow pipe 2 and are housed within the box body 1. Each branch flow pipe includes a main branch pipe and a bypass branch pipe, with their lower ends connected and their upper ends connected to the main flow pipe 2. The main branch pipe is sequentially equipped with an inlet regulating valve 3, a filter 4, a flow sensor 5, and an outlet regulating valve 6. The bypass branch pipe is equipped with a bypass regulating valve 7. The main flow pipe 2 is connected to an external lubricant storage unit via a flange.

[0027] The flow totalizer box, flow control box, and flow totalizer box are connected by cables. The flow totalizer box includes several totalizers.

[0028] The filter 4 is a Y-type filter, installed below the inlet regulating valve 3, used to remove impurities from the lubricating fluid, protecting the normal operation of the system. It has a simple structure, low resistance, and convenient drainage.

[0029] The flow sensor 5 is a miniature flow sensor or flow meter. The flow sensor 5 is connected to the totalizer one by one through the cable to realize the accurate acquisition, fast transmission and real-time display of flow data in each main branch pipe.

[0030] refer to Figure 4 As shown, the totalizer is equipped with a display unit and a data processing unit. The data processing unit receives the data collected by the flow sensor 5 and calculates the flow information on the corresponding main branch pipe. The display unit displays the flow information in real time.

[0031] The inlet regulating valve 3 and the outlet regulating valve 6 are ball valves used to regulate the input and output flow rates in the flow branch pipe, ensuring that the flow rate at the lubrication point is within a suitable range.

[0032] The lower end of the flow branch pipe extends out of the flow control box 1 and is equipped with a quick connector 8. The quick connector 8 connects to a hose, through which lubricant is delivered to the part to be lubricated.

[0033] Miniature flow sensors are highly adaptable to the viscosity of the liquid being measured, and have no special requirements for pressure changes or straight pipe sections before and after the liquid being measured. They can also work and measure even small flow rates and gravity flow.

[0034] The flow control box and flow totalizer box are designed as separate units, which reduces the system's installation size and facilitates centralized observation and unified management. The totalizer performs real-time calculations and processing on the data collected by the miniature flow sensor, and displays the flow information of the corresponding branch on the screen in real time.

[0035] In this embodiment, the bypass regulating valve 7 is a ball valve. The function of the bypass regulating valve is to ensure that the normal lubrication of the equipment is not affected when the components on the main branch pipe, such as the flow sensor 5, are damaged and need to be maintained offline, so as to achieve maintenance without stopping the machine and improve the effective operating rate of the equipment.

[0036] The flow branch pipe is equipped with a three-port connector, which includes a first interface, a second interface, and a third interface. The first interface is connected to the outlet regulating valve 6, the second interface is connected to the bypass regulating valve 7, and the third interface is connected to the quick connector 8.

[0042] The inlet control valve, outlet control valve, and bypass control valve are ball valves, which can be manually controlled by manual ball valves or automatically controlled by electric ball valves.

[0043] In summary, the technical solution of this utility model fully considers the limited installation space inside the equipment and the large number of circuits requiring lubrication. It adopts a split-type flow meter design, with separate flow control boxes and flow totalizer boxes. The flow totalizer box can be installed externally and connected to the flow control box via cables, greatly reducing the system's installation volume and saving space.
