Description

Technical Field

[0001] The utility model relates to the field of mechanical equipment lubrication, in particular to a blockage detection device for a lubrication system and a lubrication system. Background Art

[0002] In the operation and maintenance of mechanical equipment, correct and efficient lubrication not only ensures the smooth operation of mechanical parts such as bearings and gears, but also significantly extends the service life of the equipment. Lubricants reduce direct contact between metal surfaces by forming a protective film, thereby reducing friction and wear and improving operating efficiency. In addition, lubrication also helps with heat dissipation, corrosion prevention, cleaning and sealing. It helps mechanical parts maintain a suitable operating temperature and prevents the accumulation of dust and other impurities. However, improper or insufficient lubrication will lead to increased friction, which in turn causes temperature rise, component wear and even equipment failure.

[0003] Traditional lubrication methods, such as manually applying grease or using a lubricating pinion, are simple to operate, but lack efficiency and uniformity in lubrication. These methods often cannot adapt to rapidly changing operating conditions and are highly dependent on the operator's skills. With the development of industrial automation, the use of electric lubrication pumps is becoming increasingly popular. Electric lubrication pumps are used to automate lubrication to improve lubrication efficiency and consistency. They are responsible for automatically delivering lubricating oil to key parts of the machinery. The plunger pair in the electric lubrication pump is responsible for driving the flow of lubricating oil, while the relief valve controls and maintains the pressure level in the system, ensuring that the lubricating oil is delivered at the appropriate pressure.

[0004] Although the automated lubrication system improves the operating efficiency of the equipment and reduces the need for manual intervention, there is still a risk of blockage in some components, especially the plunger pair or the overflow valve. This blockage is usually difficult to observe from the outside. Once it occurs, it not only affects the lubrication effect, but may also cause equipment failure and increase maintenance costs. For this reason, a blockage detection device for the lubrication system is urgently needed. Utility Model Content

DETAILED DESCRIPTION

[0027] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0028] In the prior art, manual or automated methods are usually used to distribute lubricants to ensure that industrial machinery and equipment such as bearings and gears are properly lubricated to reduce wear and extend service life. In these traditional systems, electric lubrication pumps are widely used to automatically deliver lubricants. These pumps usually rely on basic mechanical components, such as plunger pairs, to control and maintain the flow and pressure of the lubricant. Although this setting is effective to a certain extent, it has limitations in real-time monitoring and blockage prevention. For example, when a lubrication system is blocked, traditional systems often have difficulty detecting and responding in a timely manner, which may lead to insufficient or interrupted lubricant supply, thereby affecting the performance and life of mechanical equipment. In addition, most existing technologies lack efficient remote monitoring. In complex industrial environments, it is very important to quickly respond to and maintain faults.

[0029] Existing technologies have some problems with lubrication system blockage detection. For example, traditional lubrication systems often lack real-time and accurate blockage detection capabilities, which may lead to insufficient or excessive lubrication, thus affecting the operating efficiency and life of mechanical equipment. In addition, even if some systems have basic monitoring functions, they are still limited in response speed and fault diagnosis. These limitations are particularly evident in industrial applications that require fast responses. In terms of remote monitoring and control, existing technologies are usually unable to provide timely feedback.

[0030] In response to these problems, a blockage detection device for the lubrication system is proposed. The blockage detection device can monitor the status of the lubrication system in real time and accurately, and quickly respond to potential blockages. Through the pressure sensing mechanism, combined with a sensitive normally closed contact switch and a multi-function alarm module (including optical and sound alarms), it is ensured that the alarm can be quickly activated when there are signs of blockage, and maintenance personnel are notified in time. In addition, a remote communication module is set up to provide remote monitoring and control capabilities, ensuring equipment safety and operating efficiency regardless of the environment.

[0031] In order to make the above-mentioned purposes, features and advantages of the embodiments of the utility model more obvious and easy to understand, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0032] The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0033] like Figures 1 to 3As shown, the utility model provides a blockage detection device for a lubrication system, which is intended to monitor the state of the lubrication system in real time to prevent and identify potential blockage problems. The blockage detection device includes a relief valve 10, a pressure sensing mechanism 20 and a remote communication module 30. And the lubricating oil flows through the relief valve 10 through the lubricating pipeline 102. The lubricating oil flows through the lubricating pipeline 102 and is responsible for transporting the lubricating oil from the storage area to the key parts of the mechanical equipment. The relief valve 10 is provided with a valve body 101, the lubricating pipeline 102 runs through the valve body 101, and a through hole connected to the lubricating pipeline 102 is provided on the side wall of the valve body 101. The relief valve 10 not only controls the flow of the lubricating oil, but also maintains the pressure balance in the lubricating system. The relief valve 10 is provided with a valve body 101, and the lubricating pipeline 102 runs through the entire valve body 101. This design allows the lubricating oil to pass through the valve body 101 smoothly, and also enables the valve body 101 to exert necessary control on the flow of the lubricating oil. On the side wall of the valve body 101, there is a through hole connected to the lubricating pipeline 102, and the through hole can be one or more. The sensing input end of the pressure sensing mechanism 20 is set at the through hole, and the through hole is directly connected to the lubricating pipeline 102, allowing the pressure of the lubricating oil to be transmitted to the pressure sensing mechanism 20. This enables the pressure sensing mechanism 20 to directly sense the pressure change of the lubricating oil flowing through the lubricating pipeline 102. The sensing output end is connected to the trigger module 50, and is connected to the alarm module 40 through the trigger module 50. Once an abnormal pressure is detected (usually a pressure increase or decrease caused by a blockage), the sensing mechanism will activate the trigger module 50 connected thereto. This trigger module 50 then transmits a signal to the alarm module 40 to alert the operator or maintenance personnel.

[0034] Further, the alarm module 40 includes an optical alarm and an audible alarm, both of which are electrically connected to the controller 60. A dual warning mechanism is provided by the optical alarm and the audible alarm to ensure that any potential problems can be noticed in time. Both the optical alarm and the audible alarm are directly electrically connected to the controller 60, ensuring that a quick response can be made when an abnormality is detected. The optical alarm preferably uses a warning light 401. In design, these warning lights 401 usually choose eye-catching colors, such as red or orange, to ensure that they can be clearly seen even in low light or at a long distance. When a blockage or other abnormal situation is detected, the controller 60 triggers these warning lights 401 to issue a visual alarm. Even in a noisy industrial environment, it can also remind the staff in time. At the same time, the audible alarm usually uses a buzzer 402. The buzzer 402 can emit a high-decibel alarm sound, which ensures that the warning information can be conveyed in time when the visual signal is ignored or not seen. When the buzzer 402 is activated, a continuous or intermittent sound signal is emitted to increase awareness of the emergency. This design, which combines optical and audible alarms, increases the effectiveness of safety alarms and ensures that any important safety information will not be missed even in complex or noisy working environments.

[0035] The remote communication module 30, the trigger module 50 and the alarm module 40 are all electrically connected to the controller 60. This means that once a blockage is detected, not only will the local alarm be activated, but the remote communication module 30 can also send the blockage information to a remote monitoring center or mobile device to ensure timely response and processing. Preferably, a wireless transmitter is used. In this way, the entire blockage detection device improves the reliability of the lubrication system, reduces the risk of equipment failure, and improves the overall equipment maintenance efficiency.

[0036] On this basis, a cavity is provided on the valve body 101, and the lubricating pipeline 102 is connected to the cavity through a through hole. In this blockage detection device, a cavity directly connected to the lubricating pipeline 102 is set inside the valve body 101. The connection point is a through hole on the side wall of the valve body 101. The sensing input end of the pressure sensing mechanism 20 is set in the cavity, and the sensing output end is connected to the trigger module 50 by penetrating the side wall of the valve body 101. That is, the sensing input end of the pressure sensing mechanism 20 is located in this cavity. The function of this sensing input end is to monitor the pressure change of the lubricating pipeline 102 as an indicator of the operating status of the lubrication system. When the sensing input end detects any abnormal pressure change, it will transmit this signal to the sensing output end. The sensing output end is a bridge for communication with the outside world. It penetrates the side wall of the valve body 101 and is connected to a trigger module 50. This trigger module 50 is the next link in the reaction chain. It is responsible for receiving signals from the sensing mechanism and activating the alarm module 40 or issuing other types of responses based on these signals. This not only improves the sensitivity of detecting blockage, but also improves the reaction speed. By creating such a cavity inside the valve body 101 and connecting it to the lubrication pipeline 102 through a through hole, the blockage detection device can monitor the status of the entire lubrication system more directly and accurately, thereby ensuring the efficient and safe operation of the equipment.

[0037] The further pressure sensing mechanism 20 includes a push rod 202 and a sensing piston 201, the combined operation of which provides an efficient way to detect and transmit pressure changes in the lubrication system. One end of the push rod 202 is connected to the sensing piston 201, and the other end penetrates the side wall of the valve body 101 and is connected to the trigger module 50. The other end surface of the sensing piston 201 is arranged in contact with the through hole, so that the sensing piston 201 can directly sense the pressure changes at the through hole. When the lubricating oil passes through the lubricating pipeline 102 and the through hole, any pressure changes will be immediately transmitted to the sensing piston 201. In order to ensure flexibility and accurate response, the sensing piston 201 is slidably connected to the side wall of the cavity, and this connection method ensures that the sensing piston 201 can move freely when receiving pressure changes. The push rod 202 can convert pressure sensing into a detectable signal. One end of it is fixedly connected to the sensing piston 201, and the other end penetrates the side wall of the valve body 101 and is connected to the external trigger module 50. When the sensing piston 201 senses the pressure change and moves, this movement is transmitted to the trigger module 50 through the push rod 202, and the trigger module 50 then activates the corresponding response mechanism, such as starting the alarm module 40 or sending a signal to the controller 60. A compression spring 203 is sleeved on the push rod 202, one end of the spring 203 is in contact with the sensing piston 201, and the other end is connected to the inner wall of the cavity. In order to ensure the smooth operation of the push rod 202 and the sensing piston 201, a compression spring 203 is also provided. This spring 203 is sleeved on the push rod 202, one end is in contact with the sensing piston 201, and the other end is connected to the inner wall of the cavity. This arrangement allows the sensing piston 201 to be kept stable when there is no pressure change, while providing the necessary elastic force when a pressure change occurs.

[0038] Preferably, the trigger module 50 uses a normally closed contact switch 501, and the mechanical contact of the normally closed contact switch 501 is connected to the push rod 202. The basic working principle of the normally closed contact switch 501 is that when there is no external force, the switch is in a closed state and the circuit connection is completed. This design ensures that it is always ready in the default state. The mechanical contact of this normally closed contact switch 501 is directly connected to the push rod 202 in the pressure sensing mechanism 20. The push rod 202 is a key component for detecting pressure changes in the lubrication system. When the pressure in the lubrication system changes abnormally (usually due to blockage), the sensing piston 201 and the push rod 202 will move accordingly. This movement will cause the mechanical contact of the normally closed contact switch 501 connected to the push rod 202 to be pushed, thereby causing a change in the switch state. When the normally closed contact switch 501 is opened due to the action of the push rod 202, the previously closed circuit will be disconnected, and this state change will be immediately recognized. The disconnected circuit triggers the next level of response, such as activating the alarm module 40 or notifying the controller 60. This design not only provides a simple and effective detection mechanism, but also greatly improves the reliability and response speed of the system due to its direct and physical nature.

[0039] In this blockage detection device for the lubrication system, a hollow screw 204 mechanism is provided to reduce the friction between the push rod 202 and the valve body 101 and to ensure the directional stability of the movement of the push rod 202. The application of the hollow screw 204 improves the efficiency and response speed, and also increases the reliability and durability of the blockage detection device. The hollow screw 204 is sleeved on the push rod 202 and is slidably connected to the push rod 202. Such a design allows the push rod 202 to slide freely inside the hollow screw 204. Since the center of the screw is hollow, it provides a smooth and precise guide channel for the push rod 202, effectively reducing the friction of the contact part of the push rod 202 with the valve body 101 when the push rod 202 moves. This not only protects the push rod 202 from excessive wear, but also ensures that it moves more smoothly and accurately. In addition, the structural setting of the hollow screw 204 helps to stabilize the movement direction of the push rod 202 and avoid any lateral swing or offset that may reduce the detection accuracy. The push rod 202 penetrates the valve body 101 through the hollow screw 204, so that the push rod 202 can maintain a high degree of mobility and stability even under the thickness or complex structure of the valve body 101. At the same time, the spring 203 is connected to the inner wall of the cavity through the hollow screw 204, and one end of the spring 203 is arranged in contact with one end of the hollow screw 204. The spring 203 can be effectively compressed or expanded when a pressure change occurs, providing the necessary elastic force to promote the rapid movement and return of the push rod 202. The hollow screw 204 not only optimizes the movement characteristics of the push rod 202 and reduces the friction during its movement, but also enhances the stability and response speed of the entire pressure sensing mechanism 20. This helps to quickly and accurately detect blockages in the lubrication system.

[0040] In the blockage detection device of the lubrication system, the remote communication module 30 ensures that the fault detection information can be quickly and effectively transmitted to the remote terminal. The remote communication module 30 includes at least any one of a local wireless network communication module, a cellular network communication module and a satellite network communication module, and the output end of the remote communication module 30 is electrically connected to the remote terminal. Among them, the local wireless network communication module is usually based on Wi-Fi technology and is suitable for communication within a factory or facility. It allows the detected blockage information to be quickly transmitted to the mobile device of the local control center or the maintenance team. The cellular network communication module uses a cellular network (such as 3G, 4G or 5G) for remote communication, which is suitable for equipment with a relatively scattered working environment or high mobility. The wide coverage of the cellular network ensures that stable communication can be maintained even in remote areas. And the satellite network communication module, in some remote or offshore operating environments, satellite communication provides an effective means of communication. It can cover areas that are difficult for cellular networks to reach, ensuring that key information can be communicated in a timely manner. Regardless of the communication technology used, the output end of the remote communication module 30 is electrically connected to the remote terminal. This means that once the detection device finds a potential blockage or other abnormal conditions, the relevant data and alarm information can be transmitted in real time to the remote monitoring center, the maintenance engineer's handheld device, or even directly to the management's equipment. This real-time communication capability improves the speed of response, allowing rapid measures to prevent or mitigate failures, significantly reducing the risk of equipment failure and downtime.

[0041] In order to further improve the efficiency and accuracy of the lubrication system blockage detection device, a pressure sensor is also included. The inlet and outlet of the lubricating pipeline 102 are both provided with pressure sensors, and the pressure sensors are electrically connected to the controller 60. In this way, the pressure state of the lubricating oil flowing in the entire system can be monitored in real time. Through this arrangement, any pressure changes that deviate from the normal range can be captured, and these changes are often early indicators of problems, such as pipeline blockage or pump failure. When the pressure sensor detects abnormal pressure (whether too high or too low), this information will be immediately transmitted to the controller 60. The controller 60 analyzes this data to help the staff determine the current operating status of the system. For example, if an abnormal decrease in pressure is detected at the inlet of the lubricating pipeline 102, this may indicate that there is a problem with the plunger pair 72 of the electric lubrication pump 71; if the pressure at the outlet is abnormally increased, it may indicate that the overflow valve 10 or a certain part of the pipeline is blocked. After detecting such a pressure change, it can assist the staff in formulating a corresponding maintenance strategy. For example, it can instruct the maintenance staff to check a specific lubricating oil pipeline section, or adjust the setting of the overflow valve 10. In general, the pressure sensors at the inlet and outlet of the lubrication pipeline 102 improve the efficiency and accuracy of fault diagnosis. Through the data collected by these sensors, the staff can quickly and accurately identify and respond to problems, minimize the impact of equipment failures, and ensure the smooth operation of the entire lubrication system.

[0042] Here, the working process of the blockage detection device is further described. If a certain part in the lubrication system, such as the plunger pair 72 or the relief valve 10, is blocked, this will directly affect the output pressure of the relief valve 10 (i.e., the pressure drops). At this time, when the pressure drops, the sensing piston 201 driven by the spring 203 will move inward. This inward movement affects the push rod 202 connected to the sensing piston 201, causing the position of the push rod 202 to change. Under normal conditions, the normally closed contact switch 501 remains closed due to the position of the push rod 202, ensuring that the circuit is connected. However, when the push rod 202 is disengaged from the normally closed contact switch 501 due to the inward movement of the sensing piston 201, the normally closed contact switch 501 is disconnected, thereby interrupting the connection of the circuit. Once the normally closed contact switch 501 is disconnected, the alarm module 40 is immediately activated. The alarm module 40 includes a warning light 401 and a buzzer 402. The warning light 401 provides a visual warning, while the buzzer 402 sounds an audible alarm, thereby notifying the operator of possible blockage problems in the system. The operator can take immediate measures to avoid mechanical failure or other serious problems caused by insufficient lubrication. It should be noted here that when the motor of the electric lubrication pump 71 is working, the power supply is in the on state, so that the entire system is in a monitoring state. If the motor stops working, the power supply of the blockage detection device will also be disconnected accordingly. Such a design not only saves energy, but also ensures that the alarm will not be erroneously issued in the non-working state. Overall, this workflow not only ensures that the lubrication system can detect and respond to potential blockage problems in a timely manner, but also provides an effective local and remote alarm system to ensure the safe and efficient operation of mechanical equipment in various working environments.

[0043] Furthermore, in actual large-scale industrial manufacturing facilities, there are multiple production lines, each of which is equipped with various heavy machinery and equipment, such as presses, rotating equipment and conveyor belts. These machinery and equipment require continuous and stable lubrication to ensure their efficient and safe operation during continuous operation. In such an environment, the lubrication system plays a key role. In a continuous production environment, the machinery and equipment operate continuously with almost no downtime, which puts forward high efficiency and reliability requirements for the lubrication system. The electric lubrication pump 71 continuously delivers lubricating oil to key components, and the blockage detection device can monitor the pressure condition of the system in real time. Once a part is blocked, such as due to foreign matter entering or lubricating oil pipeline wear, the pressure sensing mechanism 20 will quickly detect abnormal changes in pressure. In the control center of the production line, engineers monitor the lubrication status in real time through a monitoring system connected to the remote communication module 30. When a potential blockage problem is detected, the alarm module 40 is immediately activated, and the remote communication module 30 sends an alarm signal to the control center. Engineers can quickly identify the problem and dispatch maintenance personnel to a specific production line for processing. Through this instant fault detection and rapid response, equipment damage and production downtime that may be caused by lubrication problems are reduced. In industrial environments where production efficiency is critical, this means significant cost savings and productivity gains.

[0044] like Figure 3 As shown, the utility model provides a lubrication system, including an electric lubrication pump 71 and a blockage detection device, wherein the electric lubrication pump 71 is connected to the blockage detection device via a plunger pair 72 .

[0045] Specifically, the electric lubrication pump 71 is responsible for pushing the lubricating oil through the entire system to ensure that the mechanical parts are properly lubricated. The plunger pair 72 in the lubrication pump, through its reciprocating motion, delivers the lubricating oil to various parts of the system at a certain pressure and flow rate. The blockage detection device is used to monitor the operating status of the entire lubrication system in real time, especially paying attention to any possible blockage. Through the connection with the plunger pair 72, the blockage detection device can accurately capture the pressure changes caused by blockage. Once an abnormality is detected, such as a drop in pressure, indicating that there may be a blockage, it will respond immediately. The blockage detection device includes multiple components, such as a relief valve 10, a pressure sensing mechanism 20, a trigger module 50, an alarm module 40, and a remote communication module 30. These components work together to ensure that a timely response can be made when any signs of blockage appear. For example, after the pressure sensing mechanism 20 detects a pressure change, it will trigger the normally closed contact switch 501, thereby activating the warning light 401 and the buzzer 402 to warn the operator. At the same time, the remote communication module 30 ensures that these key information can be quickly transmitted to the remote monitoring center to ensure timely response and maintenance. The lubrication system not only takes into account the lubrication efficiency and maintenance of mechanical parts, but also pays attention to real-time monitoring and fault prevention.
