Description

Lubricating oil injection system monitoring method

The invention relates to a lubricating oil injection system, in particular to a monitoring method of a lubricating oil injection system.

The general lubricating oil injection system includes an oil injection machine, an oil inlet pipe, a distributor and a plurality of oil outlet pipes. The lubricating oil produced by the oil injection machine can be injected into the distributor through the oil inlet pipe. The distributor continuously or intermittently lubricates the oil The oil is divided and output in equal or different amounts.

In order to monitor the normal operation of the system, the traditional lubricating oil injection system detects whether the distributor has moved within a predetermined period of time. If no movement is detected within the predetermined period of time, the system is judged to be clogged or insufficiently filled with oil. As for whether the system's oil injection volume is insufficient or excessive, it is impossible to know. If you want to know the above information, there is currently a flow meter installed in the system to detect the flow of lubricating oil into the oil pipe or out of the oil pipe. However, the cost of the flow meter is high, especially thicker lubricating oil such as butter. Its dedicated flowmeter is even more expensive. Therefore, how to more accurately monitor the oil injection amount of the system, and to keep track of the status of the lubricating oil injection system at any time, without costly expenses, has become a technical problem to be solved by practitioners in the field.

The purpose of the present invention is to provide a monitoring method for a lubricating oil injection system, which can accurately monitor whether the oil injection amount of the system is within a preset range without costly expenses.

In order to achieve the above object, the monitoring method of the lubricating oil injection system of the present invention includes the following steps: (A) setting an oil injection period, an intermittent period, an upper limit of oil injection frequency and a lower limit of oil injection frequency in a microprocessor; (B) After the start of the oil filling period, the microprocessor starts an oil pump to inject lubricating oil into a distributor through an oil inlet pipe. The distributor then shunts the lubricating oil to most of the oil outlet pipes for oil injection, and detects the actual number of oil injections; (C) by the microprocessor, if the actual number of oil injections is greater than the upper limit of the number of oil injections before the end of the oil injection period, or the actual number of oil injections is less than the lower limit of the number of oil injections at the end of the oil injection period, the microprocessor Control an alarm to issue an alarm and simultaneously control the oil pump to stop; at the end of the oil injection period, the actual number of oil injections is between the lower limit of the oil injection frequency and the upper limit of the oil injection frequency, then proceed to steps (D); and (D) at When the oil injection period ends and the intermittent period starts, the microprocessor controls the oil pump to stop until the end of the intermittent period, and returns to step (B). Thereby, the monitoring method of the lubricating oil injection system can accurately monitor whether the oil injection amount of the system is within the preset range, and does not need to costly, that is, to avoid the waste of the terminal machine due to excessive oil injection or insufficient oil injection to increase the risk of damage.

The technical content and features of the present invention will be described in detail below through a preferred embodiment and drawings. Since the monitoring method of the lubricating oil injection system of the present invention can be applied to different lubricating oil injection systems, the lubrication applied by the present invention will be described first. For the structure of the oil injection system, please refer to the first figure, which is a lubricating oil injection system provided by a preferred embodiment of the present invention. The lubricating oil injection system 1 includes an electric oil injection machine 10, a distributor 20, an oil inlet pipe 16, a The sensor 50 and the four oil pipes 26.

The electric oiling machine 10 has an oil cup 12 for storing lubricating oil, a microprocessor 14, an oil pump 13 is located between the oil cup 12 and the microprocessor 14 and is electrically connected to the microprocessor 14, a The display screen 17 is electrically connected to the microprocessor 14, an alarm (not shown) is electrically connected to the microprocessor 14, and an oil outlet 15 communicates the oil cup 12 and the oil inlet pipe 16. Thereby, when the microprocessor 14 controls the oil pump 13 to start, the oil pump 13 draws the lubricating oil in the oil cup 12 to be delivered to the distributor 20 through the oil outlet 15 and the oil inlet pipe 16, and the microprocessor 14. The siren can be controlled to emit sound, light or vibration alarms. The microprocessor 14 is electrically connected to the sensor 50 and can receive signals from the sensor 50. The microprocessor 14 can control the display screen 17 to display related messages.

Next, referring to FIGS. 1 and 2, the distributor 20 is a progressive distributor, the distributor 20 has an oil inlet 23 connected to the oil inlet pipe 16, a first distribution unit 30 and the oil inlet 23 communicates with each other, and a second distribution unit 40 communicates with the first distribution unit 30, the first distribution unit 30 has a chamber 35, a piston 32 is located in the chamber 35, a detection rod 39 is connected to the The piston 32 and the two oil outlets 36 and 38 communicate with the chamber 35. The two oil outlets 36 and 38 are respectively connected to the two oil outlet pipes 26. The detection rod 39 will move up and down as the piston 32 moves Move and its end abuts the sensor 50, the structure of the second distribution unit 40 and the first distributor 30 is substantially the same, the difference is that the second distribution unit 40 does not have the detection rod 39, the second The unit 40 includes a chamber 45, a piston (not shown), and two oil outlets 46, 48 communicating with the chamber 45. The two oil outlets 46, 48 are respectively connected to the two oil outlet pipes 26. When the oil pump 13 is started, lubricating oil is injected into the distributor 20 through the oil inlet 23, and the oil pressure will push the pistons of the first and second distribution units 30, 40 to move up and down, causing the lubricating oil to pass through the oil outlet 36. , 38, 46, 48 output, and delivered to the place where lubrication is needed through the four oil pipes 26, at the same time, the detection rod 39 moves up and down together with the piston 32, by which the distributor 20 can divide the lubricating oil successively Output.

It should be noted that each time the distributor 20 circulates oil from the oil outlets 36, 38, 46, 48, the detection rod 39 will move up and down once.

The sensor 50 is a micro switch, which is located beside the distributor 20. The sensor 50 is electrically connected to the microprocessor 14 through a three-signal line 56. The sensing rod 39 can touch the sensor when it is extended. The sensor 50 can send a signal to the microprocessor 14. Therefore, the microprocessor 14 can know the number of operation cycles of the distributor 20 through the sensor 50. Since the oil output per cycle of the distributor 20 is fixed, by sensing the operation of the distributor 20 The number of cycles can be converted to obtain the actual oil output.

The monitoring method of the lubricating oil injection system of the present invention includes the following steps: First, in step (A), the user sets an oil injection period, an intermittent period, and an interval in the microprocessor 14 through an input device (not shown) according to his needs. The upper limit of oil injection frequency and the lower limit of oil injection frequency. It should be noted that the oil injection period and the intermittent period constitute a cycle period, for example: the oil injection period is 10 minutes, the intermittent period is 20 minutes, the upper limit of the oil injection frequency is 6 times, and the lower limit of the oil injection frequency is 4 times, Therefore, the entire cycle is 30 minutes.

Then, in step (B), at the beginning of the oil injection period, the microprocessor 14 controls the oil pump 13 to start, and the oil pump 13 injects the lubricating oil in the oil cup 12 into the distributor 20 through the oil inlet pipe 16 , The distributor 20 divides the lubricating oil to the oil outlets 36, 38, 46, 48 one by one, and fills the oil through the four oil outlets 26. At the same time, the sensor 50 continuously detects the piston 32 or the piston 32 of the distributor 20. Detecting the number of actuation times of the stick 39 (as the actual oil injection frequency), and transmitting the information of the actual oil injection frequency to the microprocessor 14, the microprocessor 14 can control the actual oil injection frequency to be displayed on the display screen 17 .

Next, proceed to step (C). The microprocessor 14 compares the actual number of oil injections, the upper limit of the number of oil injections and the lower limit of the number of oil injections. Before the end of the oil injection period, if the actual number of oil injections is less than or equal to the upper limit of the number of oil injections, The microprocessor 14 judges normal, and the oil pump 13 continues to operate; if the actual number of oil injections is greater than the upper limit of the number of oil injections, the microprocessor 14 determines abnormality, the microprocessor 14 controls the alarm to issue an alarm, and controls the amount of oil injected The corresponding code that is exceeded is displayed on the display screen 17 while controlling the oil pump 13 to stop.

At the end of the oil injection period, if the actual number of oil injections is less than the lower limit of the number of oil injections, the microprocessor 14 determines that it is abnormal, the microprocessor 14 controls the alarm to issue an alarm, and controls to display the corresponding code of the oil injection volume is too low On the display screen 17, the oil pump 13 is simultaneously controlled to stop; if the actual number of oil injections is between the lower limit of the number of oil injections and the upper limit of the number of oil injections, the microprocessor 14 determines that it is normal and proceeds to step (D).

Step (D) is when the oil injection period ends and the intermittent period starts, the microprocessor 14 controls the oil pump 13 to stop, and returns to step (B) until the intermittent period ends.

In other words, if the actual number of oil injections exceeds the preset upper limit or lower than the lower limit, the system will issue an alarm and display the code of the abnormal condition, and at the same time stop the oil pump 13, so that the operator can timely grasp the abnormal condition of the oil injection number and handle it immediately, It can avoid the situation of excessive oil filling or insufficient oil filling at the terminal machine, so as to extend the service life of the machine, that is, the method provided by the present invention can accurately monitor whether the oil filling amount of the system is within the preset range, and use the detection distributor The number of operations can be used to estimate the amount of oil, instead of the expensive method of directly detecting the flow rate of the conventional technology, which can save considerable manufacturing costs, thereby achieving the purpose of the present invention.

It should be noted that the structure of the lubricating oil injection system is not the focus of the present invention and can be changed. For example, the sensor 50 can use a non-contact sensor, such as a proximity switch or an infrared detector; The sensor 50 and the microprocessor 14 can transmit signals by wireless communication; or the distributor 20 is an adjustable distributor that distributes the lubricating oil in different amounts; or the lubricating oil injection system can be further based on The actual oil delivery status provides the actual oil injection times or the reference values of the upper and lower limits of the oil injection times and displays them on the display screen 17, that is, regardless of its structure, the lubrication oil injection system monitoring method of the present invention can be applied. The structure of the oil injection system cannot be used to limit the patent scope of the invention.

The above description of the embodiments of the present invention should not be used to limit the patent scope of the present invention. For example, any simple retouching or changes made without departing from the spirit of the present invention should still be covered by the patent application scope of the present invention.
