Description

Technical Field

[0001] This utility model relates to the field of grease monitoring technology, and in particular to a grease monitoring, control and protection device. Background Technology

[0002] Lubricating grease plays a crucial role in the hot rolling process, primarily providing lubrication and protection for hot rolling equipment. In hot rolling mills, on-site grease control is affected by various factors during production. The lack of comprehensive monitoring and protection devices makes it difficult to accurately monitor flow and pressure during grease delivery, and the absence of critical pressure unloading protection makes accidents prone to occur due to flow or pressure overload. Therefore, there is an urgent need to develop a grease monitoring, control, and protection device that can monitor both pressure and flow, provide pressure safety unloading protection, and control flow. This device would improve work efficiency, reduce spare parts wear, achieve effective grease detection, control, and protection, be easy to maintain, save significant energy and costs, and meet the requirements of safe on-site production. This would overcome the shortcomings of current applications and satisfy current needs. Utility Model Content

[0003] The purpose of this invention is to provide a grease monitoring, control and protection device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A grease monitoring, control, and protection device includes a flow meter, a pressure relay, an unloading valve assembly, an inlet flange, an outlet flange, a flow and pressure detector, a tee connector, and a PLC control box. The flow meter and pressure relay are fixedly connected to the upper side of the flow and pressure detector. A tee connector is fixedly connected to the right side of the flow and pressure detector. An inlet flange is fixedly connected to the right end of the tee connector. The inlet flange is connected to a grease delivery pipeline via bolts and nuts. An unloading valve assembly is installed on the tee connector. An outlet flange is fixedly connected to the left side of the flow and pressure detector. The outlet flange is connected to the grease delivery pipeline via bolts and nuts.

[0006] Preferably, the flow meter and pressure relay are electrically connected to the flow and pressure detector, respectively.

[0007] Preferably, the flow meter, pressure relay, and unloading valve assembly are electrically connected to the PLC control box.

[0008] Preferably, the flow pressure detector is made of stainless steel.

[0009] The beneficial effects of this utility model are as follows: Under normal use, the unloading valve group of this grease monitoring and control protection device is in the closed state. The grease delivery pipeline delivers the grease from the inlet flange to the flow and pressure detector. The flow and pressure detector is used to detect the flow rate and pressure, and feeds back the detection data to the flow meter and pressure relay. The flow meter and pressure relay are preset with upper limits for flow rate and pressure. If the flow rate and pressure of the grease are less than the upper limits, the grease passes through the flow and pressure detector and flows back to the grease delivery pipeline from the outlet flange. If the flow rate or pressure of the grease is less than the upper limits, the flow meter or pressure relay sends a signal to the PLC control box. The PLC control box controls the unloading valve group to open for protective unloading, thereby preventing accidents caused by flow or pressure overload in the entire grease system. In summary, this utility model can monitor both pressure and flow, provide pressure safety unloading protection, and control flow, thereby improving work efficiency, reducing spare parts wear, achieving the effect of grease detection, control, and protection, facilitating maintenance, saving a lot of energy and costs, and meeting the needs of on-site safe production.

[0014] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0015] Specific implementation examples are given below.

[0016] See Figures 1-2In this embodiment of the present invention, a grease monitoring, control, and protection device includes a flow meter 1, a pressure relay 2, an unloading valve group 3, an inlet flange 4, an outlet flange 5, a flow and pressure detector 6, a tee connector 7, and a PLC control box 8. The flow meter 1 and the pressure relay 2 are fixedly connected to the upper side of the flow and pressure detector 6, and the flow meter 1 and the pressure relay 2 are electrically connected to the flow and pressure detector 6. The tee connector 7 is fixedly connected to the right side of the flow and pressure detector 6, and the inlet flange 4 is fixedly connected to the right end of the tee connector 7. The inlet flange 4 is connected to a grease delivery pipeline via bolts and nuts, and the grease delivery pipeline delivers grease from the inlet... The flow rate and pressure are fed into the flow and pressure detector 6 at flange 4. The flow and pressure detector 6 is used to detect the flow rate and pressure. The flow and pressure detector 6 feeds back the detection data to the flow meter 1 and the pressure relay 2. The flow meter 1 and the pressure relay 2 are preset with upper limits for flow rate and pressure. The tee joint 7 is equipped with an unloading valve group 3, which is used for unloading protection. During normal operation, the unloading valve group 3 is in the closed state. The left side of the flow and pressure detector 6 is fixedly connected to the outlet flange 5. The outlet flange 5 is connected to the grease delivery pipeline by bolts and nuts. The grease flowing out of the flow and pressure detector 6 flows back into the grease delivery pipeline from the outlet flange 5.

[0017] The flow meter 1, pressure relay 2, and unloading valve group 3 are electrically connected to the PLC control box 8, and the PLC control box 8 controls the signals to enable rapid response.

[0018] The flow and pressure detector 6 is made of 304 stainless steel, which gives it good corrosion resistance.

[0019] Working principle: Under normal use, the unloading valve group 3 of this grease monitoring and control protection device is in the closed state. The grease delivery pipeline delivers grease from the inlet flange 4 to the flow and pressure detector 6. The flow and pressure detector 6 is used to detect the flow rate and pressure, and feeds back the detection data to the flow meter 1 and the pressure relay 2. The upper limit of the flow rate and the upper limit of the pressure are preset in the flow meter 1 and the pressure relay 2. If the flow rate and pressure of the grease are less than the upper limit of the flow rate and the upper limit of the pressure, the grease passes through the flow and pressure detector 6 and flows back to the grease delivery pipeline from the outlet flange 5. If the flow rate or pressure of the grease is less than the upper limit of the flow rate and the upper limit of the pressure, the flow meter 1 or the pressure relay 2 sends a signal to the PLC control box 8. The PLC control box 8 controls the unloading valve group 3 to open for protective unloading, thereby preventing accidents caused by flow or pressure overload in the entire grease system.
