Description

Lubrication oil filling system monitoring method

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

The general lubrication oil filling system comprises a oil filling machine, an oil inlet pipe, a distributor and a plurality of oil discharge pipes, and the lubricating oil from the oiling machine can be injected into the distributor through the oil inlet pipe, and the distributor continuously or intermittently lubricates the oil filling device. The oil is split by equal or unequal amount of output.

In order to monitor whether the system is operating normally, the conventional lubrication oil filling system detects whether the dispenser has an action within a predetermined period of time. If no action is detected within the predetermined time period, it is determined that the system has an abnormal condition such as clogging or insufficient oil filling. As for whether the oil filling of the system is insufficient or excessive, it is impossible to know. If you want to know the above information, a flow meter is added to the system to detect the flow of lubricating oil into the oil pipe or the oil pipe. However, the cost of the flow meter is high, especially thick oil such as butter. Its dedicated flow meter is more expensive. Therefore, how to accurately monitor the oil filling amount of the system and grasp the condition of the lubricating oil filling system at any time without costly is a technical problem to be solved by practitioners in the field.

It is an object of the present invention to provide a lubrication oil filling system monitoring method that can accurately monitor whether the oil filling amount of the system is within a preset range without costly.

In order to achieve the above object, the lubricating oiling system monitoring method of the present invention comprises the following steps: (A) setting a fueling period, an intermittent period, an upper limit of the number of oilings of the dispenser, and a lower limit of the number of oiling times of the dispenser; B) after the start of the oiling period, the microprocessor starts an oil pump, The lubricating oil is injected into a distributor through an oil inlet pipe, and the distributor then separately distributes the lubricating oil to a plurality of oil discharge pipes for oil injection, and simultaneously detects the actual oil filling times of the distributor; (C) is compared by the microprocessor. The microprocessor controls an alarm if the actual dispenser oil filling time is greater than the upper limit of the oil filling number of the dispenser before the end of the oiling period, or the actual oil filling number of the dispenser is less than the lower limit of the oil filling frequency of the dispenser at the end of the oil filling period Sending an alarm while controlling the oil pump to stop; at the end of the oiling period, the actual dispenser oiling time is between the lower limit of the oil filling number of the dispenser and the upper limit of the oil filling frequency of the dispenser, then performing step (D); and (D) At the end of the oiling period and at the beginning of the intermittent period, the microprocessor controls the oil pump to stop until the end of the intermittent period, returning to step (B). Thereby, the lubrication oil filling system monitoring method can accurately monitor whether the oil filling amount of the system is within a preset range, and does not need to be expensive, that is, the end machine is prevented from being wasted due to excessive oiling or insufficient oiling to increase the risk of damage.

The display screen 17 is electrically connected to the microprocessor 14 , and an alarm device (not shown) is electrically connected to the microprocessor 14 . And an oil outlet 15 connects 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 the distributor 20 via the oil outlet 15 and the oil inlet pipe 16, and the microprocessor 14 can control the alarm to emit an alarm such as sound, light or vibration. The microprocessor 14 is electrically connected to the sensor 50 and can receive the signal of the sensor 50. The microprocessor 14 can control the display screen 17 to display related information.

Referring to Figures 1 and 2, the dispenser 20 is a progressive distributor having an oil inlet 23 connected to the oil inlet pipe 16, a first distribution unit 30 and the oil inlet port. 23 is interconnected, and a second distribution unit 40 is in communication with the first distribution unit 30. The first distribution unit 30 has a chamber 35, a piston 32 is located in the chamber 35, and a detecting rod 39 is connected thereto. The piston 32 and the two oil outlets 36, 38 are in communication with the chamber 35. The two oil outlets 36, 38 are respectively connected to the two oil outlet pipes 26, wherein the detecting rod 39 moves up and down with the piston 32. Moving and the end thereof abuts the sensor 50, the second dispensing unit 40 is substantially identical in structure to the first dispenser 30, except that the second dispensing unit 40 does not have the detecting stick 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 connected to the two oil outlet tubes 26, respectively. When the oil pump 13 is started, the lubricating oil is injected into the distributor 20 through the oil inlet 23, and the oil pressure pushes the pistons of the first and second distribution units 30, 40 up and down to make the lubricating oil pass through the respective oil outlets 36. , 38, 46, 48 output, and through the four oil outlet pipe 26 to provide lubrication, and at the same time, the detecting rod 39 moves up and down together with the piston 32, whereby the distributor 20 can separately divert the lubricating oil Output.

It should be noted that the distributor 20 outputs lubricating oil once for each of the oil outlets 36, 38, 46, 48, and the detecting rod 39 moves up and down once.

The sensor 50 is a micro switch that is disposed adjacent to the distributor 20. The sensor 50 is electrically connected to the microprocessor 14 by a three-signal line 56. The sense stick 39 can sense the feeling when it is extended. The sensor 50, the sensor 50 can transmit signals 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 of the distributor 20 is fixed per cycle, That is, the amount of oil per oiling of the distributor 20 is fixed. Therefore, by sensing the number of operating cycles of the distributor 20, the actual amount of oil discharged can be converted.

The lubricating oiling system monitoring method of the present invention comprises the following steps: First, in step (A), the user sets an oiling period, an intermittent time period, and a microprocessor 14 to the microprocessor 14 according to a demand thereof through an input device (not shown). The upper limit of the number of times the dispenser is filled and the lower limit of the number of times the dispenser is filled. It should be noted that the oiling period and the intermittent period constitute a cycle period, for example, the oiling period is 10 minutes, the intermittent period is 20 minutes, the upper limit of the oil filling number of the distributor is 6 times, and the lower limit of the oil filling number of the distributor It is 4 times, so the whole cycle is 30 minutes.

Next, in step (B), at the beginning of the oiling 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 via the oil inlet pipe 16. The distributor 20 successively diverts the lubricating oil to the oil outlets 36, 38, 46, 48, and oils through the four oil outlet pipes 26, while the sensor 50 continuously detects the piston 32 of the distributor 20 or Detecting the number of actuations of the rod 39 (as the actual number of times the dispenser is filled), and transmitting information about the actual number of times the dispenser is filled to the microprocessor 14, the microprocessor 14 controls the number of times the actual dispenser is filled On the display screen 17.

Then, proceeding to step (C), the microprocessor 14 compares the number of times of oiling the actual dispenser, the upper limit of the number of times the dispenser is filled, and the lower limit of the number of times the dispenser is filled, before the end of the oiling period, if the actual dispenser is filled Less than or equal to the upper limit of the number of times of oiling of the dispenser, the microprocessor 14 determines normal, the oil pump 13 continues to operate; if the actual number of oil fillings of the dispenser is greater than the upper limit of the number of oil fillings of the dispenser, the microprocessor 14 determines that the abnormality, the microprocessor The controller 14 controls the alarm to issue an alarm, and controls to display a corresponding code indicating that the amount of oil is exceeded on the display screen 17, while controlling the oil pump 13 to stop.

At the end of the oiling period, if the actual dispenser oil filling number is less than the dispenser oiling frequency lower limit, the microprocessor 14 determines that the abnormality, the microprocessor 14 controls the alarm to issue an alarm, and controls the corresponding oil filling amount to be too low. The code is displayed on the display screen 17 while controlling the oil pump 13 to stop; The actual number of times the dispenser is filled is between the lower limit of the number of times the dispenser is filled and the upper limit of the number of times the dispenser is filled. The microprocessor 14 determines that it is normal and proceeds to step (D).

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

In other words, if the actual dispenser oil filling time 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 stop the oil pump 13 so that the operator can grasp the abnormal condition of the dispenser oil filling time in time. And the immediate treatment can avoid the situation that the end machine has excessive oiling or insufficient oiling to extend the service life of the machine, that is, the method provided by the invention can accurately monitor whether the oil filling amount of the system is within a preset range, and utilizes Detecting the number of times the dispenser is actuated to estimate the amount of oil, instead of the expensive method of directly detecting the flow rate by conventional techniques, can save considerable manufacturing costs, thereby achieving the object of the present invention.

It should be noted that the structure of the lubrication oil filling system may not be changed in the focus of the present invention. For example, the sensor 50 may adopt a non-contact sensor such as a proximity switch or an infrared detector; The sensor 50 and the microprocessor 14 can transmit signals in a wireless communication manner; or the lubrication oil filling system can further provide a reference to the actual number of oil injections of the dispenser or the upper and lower limits of the number of oil injections of the dispenser according to the actual oil delivery condition. The value is displayed on the display screen 17, that is, regardless of its structure, the lubricating oil filling system monitoring method of the present invention can be applied, and the structure of the lubricating oil filling system cannot be used to limit the scope of the patent of the present invention.
