Description

Technical Field

[0001] This utility model relates to the field of plunger pump technology, and in particular to a plunger lubrication device for a reciprocating plunger pump. Background Technology

[0002] In industrial production, reciprocating piston pumps are widely used in many fields such as oil extraction, chemical material transportation, and high-pressure water supply for power systems. The piston, as the core moving component of the piston pump, undergoes high-frequency reciprocating linear motion inside the pump body. During this process, friction between the piston and the pump body is unavoidable. Improper lubrication can easily lead to wear, overheating, and even jamming, severely affecting the operational stability, service life, and efficiency of the piston pump.

[0003] Existing plunger lubrication technologies have many drawbacks. Traditional manual lubrication methods not only require a lot of manpower, but also make it difficult to accurately control the lubrication interval, making them unsuitable for complex and changing working conditions. They are also prone to causing excessive wear of the plunger due to untimely lubrication. Utility Model Content

[0004] To address the above problems, this utility model provides a reciprocating plunger pump plunger lubrication device.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] A reciprocating plunger pump plunger lubrication device includes a lubricating oil storage and replenishment module, a flow control module, a lubricating oil distribution module, a working condition monitoring module, and a remote monitoring module. The lubricating oil storage and replenishment module consists of a lubricating oil tank made of high-strength, corrosion-resistant material to meet the lubrication requirements of long-term continuous operation. The top of the lubricating oil storage and replenishment module has a well-sealed oil inlet for convenient periodic lubrication replenishment. A filter screen is also installed at the oil inlet to effectively filter out impurities and prevent them from entering the lubricating oil tank and contaminating it. An oil outlet pipe is located at the bottom of the lubricating oil tank, connecting it to the flow control module. A level sensor is installed inside the lubricating oil tank to monitor the lubricating oil level in real time and transmit the signal to the control module. When the level falls below a preset minimum level, the level sensor triggers an alarm to remind the operator to replenish the lubricating oil in time, ensuring the continuous and stable operation of the lubrication device.

[0007] Preferably, the flow control module is equipped with an intelligent flow control valve, which integrates a flow regulation mechanism and a control chip. The flow regulation mechanism is an electric regulating valve, which can precisely adjust the valve opening according to the instructions issued by the control chip, thereby achieving precise control of the lubricating oil flow. The control chip has data processing capabilities, receives real-time data such as the working pressure, temperature, and piston movement frequency of the plunger pump from the working condition monitoring module, and analyzes and processes this data according to the internally preset lubrication strategy and algorithm.

[0008] Preferably, when the working condition monitoring module reports an increase in the working pressure of the plunger pump, it indicates an increase in the friction between the plunger and the pump body. At this time, the control chip automatically increases the opening of the flow control valve to increase the supply of lubricating oil and ensure good lubrication. When the working pressure decreases, the control chip correspondingly reduces the valve opening to avoid wasting lubricating oil.

[0009] Preferably, the lubricating oil distribution module includes a distributor, the inlet of which is closely connected to the outlet of the flow control valve in the flow control module through a pipeline. The distributor is designed with multiple independent and finely machined diversion channels inside, and its outlet end is provided with multiple oil outlets, the number of which corresponds one-to-one with the number of plungers in the plunger pump.

[0010] Preferably, each of the oil outlets is connected to the corresponding plunger lubrication point through an independent lubrication pipe. The distributor can evenly distribute the lubricating oil from the flow control module to each lubrication pipe in a precise ratio, ensuring that each plunger can obtain an appropriate and stable supply of lubricating oil, thus avoiding the problem of insufficient lubrication of some plungers due to uneven distribution of lubricating oil, which would aggravate wear.

[0011] Preferably, the operating condition monitoring module consists of a pressure sensor, a temperature sensor, and a displacement sensor. The pressure sensor is installed inside the pump body of the plunger pump near the plunger's movement area to monitor the hydraulic pressure changes inside the pump body in real time. The temperature sensor is installed at the contact point between the plunger and the pump body to accurately measure the real-time temperature of the plunger during operation. The displacement sensor is installed on the plunger's drive mechanism to monitor the displacement changes of the plunger and calculate the plunger's movement frequency. The sensors convert the collected pressure, temperature, and displacement data into electrical signals and transmit them in real time to the control chip of the flow control module and the remote monitoring module through signal transmission lines.

[0012] Preferably, the remote monitoring module includes a data receiving and processing unit, a display interface, and a control command sending unit. The data receiving and processing unit establishes a connection with the sensors of the operating condition monitoring module and the control chip of the flow control module through wireless communication technology, and receives various data information from them in real time. After processing, the received data is presented on the display interface in the form of intuitive charts, numbers, etc., including key parameters such as the real-time working pressure and temperature of the plunger pump, the plunger movement frequency, the lubricating oil flow rate, and the lubricating oil tank level. The operator can understand the operating status of the lubrication device and the plunger pump at any time through the display interface. At the same time, the remote monitoring module also has a control command sending function. When the operator finds that certain parameters are abnormal or needs to make specific settings to the lubrication device, he / she can send the corresponding control command to the control chip of the flow control module through the control command sending unit to achieve the purpose of remotely controlling the lubrication device.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In the lubricating oil storage and replenishment module, the oil tank, made of high-strength, corrosion-resistant material, can stably store lubricating oil for extended periods in harsh industrial environments. The filter screen at the oil inlet effectively filters impurities, ensuring the purity of the lubricating oil. A level sensor and alarm device work in tandem to promptly remind users to replenish lubricating oil, preventing plunger wear or equipment malfunction due to insufficient lubricating oil and ensuring the continuous and stable operation of the lubrication system.

[0015] 2. The intelligent flow control valve within the flow control module, leveraging the fast response and high precision of electric regulating valves, accurately adjusts the valve opening based on operating condition monitoring data received by the control chip and preset lubrication strategies. It increases the lubricating oil supply when the working pressure increases and decreases the supply when the pressure decreases, achieving precise and efficient utilization of lubricating oil, reducing wear, and avoiding waste.

[0016] 3. The lubricating oil distribution module features a sophisticated distributor design with multiple fine-tuning channels and corresponding oil outlets, ensuring precise and even distribution of lubricating oil to each plunger lubrication point. This effectively prevents insufficient lubrication and accelerated wear in some plungers due to uneven lubrication distribution, significantly improving the stability and reliability of the plunger pump operation.

[0023] Reference Figure 1-2 A reciprocating plunger pump plunger lubrication device, comprising:

[0024] Lubricating oil storage and replenishment module 1

[0025] The lubricating oil storage and replenishment module 1 mainly consists of a lubricating oil tank. Considering the complexity of the industrial environment and the requirements of long-term continuous operation, the lubricating oil tank is made of high-strength, corrosion-resistant material. This material not only effectively resists the erosion of various corrosive media, extending the service life of the oil tank, but also ensures a reliable supply of lubricating oil to the plunger pump under harsh operating conditions.

[0026] The lubricating oil tank features a well-sealed filling port on top, greatly facilitating regular lubrication replenishment by staff. A filter screen is installed at the filling port, and its role is crucial. During routine refueling, impurities from the external environment, such as dust and particles, can easily enter the oil tank along with the lubricating oil. The filter screen effectively filters out these impurities, preventing them from entering the lubricating oil tank and contaminating it, thus ensuring the purity of the lubricating oil and providing a fundamental guarantee for stable lubrication of the plunger pump.

[0027] An oil outlet pipe is located at the bottom of the lubricating oil tank. This pipe serves as the channel for the lubricating oil to flow to subsequent modules and connects to the flow control module. Inside the lubricating oil tank, a level sensor is installed. This sensor acts as a faithful "guardian," monitoring the lubricating oil level in real time. It converts the level signal into an electrical signal and transmits it to the control module. When the level falls below a preset minimum value, the level sensor quickly triggers an alarm device. The alarm device can use various methods, such as audible and visual alarms, to remind personnel to replenish the lubricating oil in time. This design ensures the continuous and stable operation of the lubrication system, preventing plunger wear or even equipment failure due to insufficient lubricating oil.

[0028] Flow control module 2

[0029] Flow control module 2 plays a core regulatory role in the entire lubrication system. This module contains an intelligent flow control valve, which boasts a sophisticated internal structure and powerful functionality. The intelligent flow control valve integrates a flow regulation mechanism and a control chip. The flow regulation mechanism employs an electric regulating valve, characterized by its fast response and high adjustment accuracy. It can precisely adjust the valve opening according to the instructions issued by the control chip, thereby achieving accurate control of the lubricating oil flow.

[0030] As the "brain" of the intelligent flow control valve, the control chip possesses powerful data processing capabilities. It receives real-time data from the operating condition monitoring module, including the plunger pump's working pressure, temperature, and plunger movement frequency. Internally, the control chip has a pre-set, scientifically sound lubrication strategy and algorithm. Upon receiving operating condition data, the control chip performs in-depth analysis and processing based on these pre-set strategies and algorithms.

[0031] For example, when the operating condition monitoring module reports an increase in the plunger pump's working pressure, this typically indicates increased friction between the plunger and the pump body. In this situation, the control chip automatically issues a command to increase the opening of the flow control valve, allowing more lubricating oil to flow to the plunger, increasing the oil supply to ensure good lubrication and reduce wear between the plunger and the pump body. Conversely, when the working pressure decreases, the control chip correspondingly decreases the valve opening to avoid wasting lubricating oil, achieving precise and efficient use of the lubricating oil.

[0032] Lubricating oil distribution module 3

[0033] The core component of the lubricating oil distribution module 3 is the distributor. The distributor's inlet is tightly connected to the outlet of the flow control valve in the flow control module via a pipe, ensuring smooth flow of lubricating oil into the distributor. The distributor's interior features multiple independent and finely machined distribution channels, acting like capillaries to evenly distribute the lubricating oil to various parts. Its outlet end has multiple oil outlets, the number of which corresponds one-to-one with the number of plungers in the plunger pump.

[0034] Each oil outlet is connected to its corresponding plunger lubrication point via an independent lubrication pipe. The distributor can evenly distribute the lubricating oil from the flow control module to each lubrication pipe in a precise ratio. This precise distribution method ensures that each plunger receives an appropriate and stable supply of lubricating oil. In actual operation, uneven lubrication distribution may lead to insufficient lubrication of some plungers, thereby accelerating wear and affecting the overall performance and lifespan of the plunger pump. The lubrication distribution module of this device effectively avoids this problem, greatly improving the operational stability and reliability of the plunger pump.

[0035] Operating condition monitoring module

[0036] The operating condition monitoring module consists of a pressure sensor, a temperature sensor, and a displacement sensor. The pressure sensor is installed inside the plunger pump body near the plunger's movement area. This location allows for the most direct and real-time monitoring of hydraulic pressure changes within the pump body. Fluctuations in the internal pressure of the pump body reflect the stress on the plunger during operation. By monitoring and analyzing the pressure data, the working status between the plunger and the pump body can be understood in a timely manner.

[0037] The temperature sensor is installed at the contact point between the plunger and the pump body, a critical area for heat generation. The temperature sensor accurately measures the real-time temperature of the plunger during operation. Excessively high temperatures may indicate poor lubrication or excessive friction between the plunger and the pump body. By monitoring the temperature data, potential problems can be identified and addressed promptly.

[0038] A displacement sensor is installed on the plunger's drive mechanism. By monitoring changes in the plunger's displacement, the plunger's motion frequency is calculated. The plunger's motion frequency is one of the important parameters for measuring the working state of a plunger pump, and it is closely related to the pump's performance indicators such as flow rate and pressure.

[0039] These sensors convert the collected pressure, temperature, and displacement data into electrical signals, which are then transmitted in real time to the control chip of the flow control module and the remote monitoring module via signal transmission lines. The signal transmission lines use highly shielded, interference-resistant cables to ensure the accuracy and stability of data transmission, unaffected by external electromagnetic interference.

[0040] Remote monitoring module

[0041] The remote monitoring module provides staff with a convenient and efficient means of monitoring and controlling equipment operation. It includes a data receiving and processing unit, a display interface, and a control command sending unit.

[0042] The data receiving and processing unit establishes a connection with the sensors of the operating condition monitoring module and the control chip of the flow control module via wireless communication technology. The wireless communication technology employs advanced communication methods such as 4G, 5G, or Wi-Fi to ensure high-speed and stable data transmission. It receives various data from them in real time, including key parameters such as the real-time operating pressure and temperature of the plunger pump, plunger movement frequency, lubricating oil flow rate, and lubricating oil tank level. After processing, the received data is presented on the display interface in the form of intuitive charts and numbers.

[0043] The display interface uses a high-resolution, high-contrast screen to clearly display various operating parameters of the equipment. Operators can monitor the operating status of the lubrication system and plunger pump at any time through the display interface. For example, by observing the changing trend of the working pressure curve, they can predict whether there are any abnormalities inside the pump; by checking the lubricating oil flow rate, they can determine whether the flow control module is working properly.

[0044] Meanwhile, the remote monitoring module also has a control command sending function. When staff discover abnormal parameters or need to make specific settings to the lubrication device, they can send corresponding control commands to the control chip of the flow control module through the control command sending unit to achieve remote control of the lubrication device. For example, if the temperature in a certain area is found to be too high, the lubricating oil flow rate in that area can be increased through the remote monitoring module to solve the problem in a timely manner, without requiring staff to go to the site in person, greatly improving work efficiency and equipment response speed.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
