Description

Technical Field

[0001] The present application relates to the technical field of oil injectors, and in particular to a lubrication system for a piston reciprocating compressor. Background Art

[0002] In the early traditional plunger lubricator system, one oil pump corresponded to one lubrication oil injection point. The drive structure of the lubricator and the reliability of the oil pump determined the performance of the lubricator and also directly affected the reliability of the continuous operation of the unit.

[0003] However, common lubricators cannot automatically adjust the oil injection amount. When the temperature changes greatly between morning and evening, the actual oil injection amount varies greatly due to the large change in lubricating oil viscosity, requiring manual regular inspection and adjustment, which not only increases the workload, but also makes it difficult to accurately control the oil injection amount. Secondly, due to the large temperature difference between morning and evening, the oil injection amount varies significantly. In order to ensure operation, the oil injection amount is generally adjusted to a larger position, consuming a large amount of lubricating oil. Utility Model Content

[0007] Through the above scheme, through the design of the eccentric disk, adjustment frame, threaded rod, adjustment block, eccentric column and eccentric roller, precise control of the stroke of each piston rod is achieved, and the oil output of each oil outlet pipe can be adjusted individually. This design makes it possible to automatically adjust the oil injection amount according to actual needs and changes in the working environment, without the need for manual regular inspection and adjustment, which greatly reduces the workload and improves the control accuracy of the oil injection amount. Therefore, it can well adapt to the changes in lubricating oil viscosity caused by temperature changes in the morning and evening. Whether in high temperature or low temperature environment, the system can maintain a stable oil injection amount, avoiding fluctuations in oil injection amount caused by changes in lubricating oil viscosity, thereby ensuring stable operation of the equipment, avoiding unnecessary waste, and achieving the purpose of energy saving and consumption reduction.

[0008] Furthermore, a motor is installed on one side of each eccentric disk, and the output end of each motor is fixedly connected to a threaded rod adjacent thereto, and the upper surface of the oil tank is fixedly connected to a refueling port.

[0009] Through the above solution, by providing the fuel filling port, it is convenient for the user to add oil to the fuel tank.

[0011] Through the above solution, by setting the oil drain port, it is convenient for the user to drain the oil.

[0012] Furthermore, a temperature transmitter is installed on the front of the oil tank.

[0013] Through the above scheme and the above settings, the temperature of the oil inside the oil tank can be monitored in real time, and the temperature signal can be converted into an electrical signal output, which is convenient for the user to monitor and adjust the oil temperature to ensure that the oil is in the optimal operating temperature range.

[0014] Furthermore, a bimetallic thermometer is installed on the front of the oil tank.

[0015] Through the above scheme and the above settings, the approximate temperature of the oil inside the oil tank can be directly read, providing the user with intuitive oil temperature information, which is convenient for quickly judging the oil temperature status.

[0037] A piston reciprocating compressor lubrication system in this embodiment realizes precise control of the stroke of each piston rod 10 through the design of an eccentric plate 3, an adjusting frame 4, a threaded rod 5, an adjusting block 6, an eccentric column 7 and an eccentric roller 8, and can thereby individually adjust the oil output of each oil outlet pipe 13. This design enables automatic adjustment of the oil injection amount according to actual needs and changes in the working environment, without the need for manual periodic inspection and adjustment, greatly reducing the workload and improving the control accuracy of the oil injection amount.

Whether in a high temperature or low temperature environment, the system can maintain a stable oil injection amount, avoiding fluctuations in the oil injection amount caused by changes in the viscosity of the lubricating oil, thereby ensuring the stable operation of the equipment, avoiding unnecessary waste, and achieving the purpose of energy saving and consumption reduction.

[0038] The working principle of the above embodiment is as follows: first, the motor 22 is started, and the power shaft 2 is driven to rotate through the coupling. The rotation of the power shaft 2 causes the multiple eccentric disks 3 fixedly connected to its outer surface to rotate accordingly. One side of each eccentric disk 3 is fixedly connected to an adjusting frame 4, and the adjusting frame 4 is internally connected to a threaded rod 5 for rotation. The threaded rod 5 is driven to rotate by the motor 24 installed on one side of the eccentric disk 3. As the threaded rod 5 rotates, the adjusting block 6 threadedly connected to it slides inside the adjusting frame 4. The sliding of the adjusting block 6 drives the movement of the eccentric column 7 fixedly connected to one side thereof, thereby changing the circumferential motion diameter of the eccentric roller 8. Since the eccentric roller 8 contacts the arc-shaped contact frame 11 at the bottom end of the piston rod 10 inside the pump housing 9, the movement of the eccentric roller 8 drives the reciprocating motion of the piston rod 10, and the reciprocating motion of the piston rod 10 The oil inside the pump housing 9 is sucked in and discharged through the oil outlet pipe 13. The top of each pump housing 9 is fixedly connected with an oil outlet pipe 13 and an oil inlet pipe 14. The oil inlet pipe 14 draws oil from the oil tank 1, and the oil outlet pipe 13 transports the oil out. In order to ensure the one-way flow of the oil, a one-way valve 15 is installed at one end of the oil outlet pipe 13 and the oil inlet pipe 14. At the same time, the temperature and liquid level of the oil inside the oil tank 1 are monitored in real time by the temperature transmitter 18, bimetallic thermometer 19, liquid level transmitter 20 and liquid level meter 21 installed on the front of the oil tank 1. These sensors convert the monitored signals into electrical signal outputs and transmit them to the control host 23. The control host 23 accurately controls the start and stop, speed, etc. of the motor 22 according to the preset parameters and logic, thereby realizing automatic control and regulation of the entire lubrication system.
