Description

Power saving method of lubricating oil injection system

The present invention relates to a lubricating oil injection system, and in particular, to a method for saving electricity of a lubricating oil injection system.

The general lubricating oil injection system includes an oil injection machine, an oil delivery pipe, a distributor, and a plurality of oil outlet pipes. The lubricating oil emitted by the oil injection machine can be injected into the distributor through the oil delivery pipe. When the oil pressure in the oil delivery pipe or the distributor reaches a predetermined After pressure, the oil injection machine stops oil injection, and the distributor can divert the internally accumulated lubricating oil through the oil outlet pipes to the place where lubrication is needed.

Because the traditional oil injection system cannot judge whether the oil pressure in the oil pipeline has reached the predetermined pressure and the time point when the predetermined pressure is reached, the user must set the operation time of the oil injection machine according to experience or by using trial and error methods. When the oil injection machine operates When the time is sufficient, the oil pressure can reach the predetermined pressure, so that the distributor can operate normally. In order to correctly set the operating time of the oil injection machine, when the oil injection system is first operated, a special person must be sent to the site to observe it. After the system operation is stable, the proper length of the oil injection machine operation time (or oil injection period) can be grasped. It takes time and effort. Without human cooperation, a long oil injection period is often set to ensure that the oil pressure has reached a predetermined pressure. However, this method may cause the oil injection time to be set too long, although the oil pressure in the pipeline has reached the required pressure, the oil injection machine continues to operate, not only wasting electricity, excessive use of the parts will also increase the probability of damage, and the oil pipeline is in a long time. High-pressure conditions tend to shorten the service life.

Even if the originally set oiling period is appropriate, after a long period of operation, the operating time of the oiling machine to reach the predetermined oil pressure may change. Therefore, how to properly set the operation of the oiling machine Time, to avoid the oil injection system being in a high voltage state for a long time, to achieve power saving effects and reduce the probability of damage, that has become a technical problem to be solved by practitioners in this field.

The purpose of the present invention is to provide a power saving method for a lubricating oil injection system, which can prevent the oil injection system from being in a high voltage state for a long time, achieve a power saving effect, and extend the service life.

In order to achieve the above object, the present invention provides a power saving method for a lubricating oil injection system, including the following steps: (A) setting a fueling period on a microprocessor; (B) starting the microprocessor when the fueling period starts An oil pump that injects lubricating oil into a volumetric distributor through an oil inlet pipe, and simultaneously measures the oil pressure in the oil inlet pipe; (C) If the oil pressure gradually increases during the oil injection period and reaches a preset pressure value , The microprocessor controls the oil pump to stop, and the lubricating oil stored in the volumetric distributor is output through most of the oil outlet pipes by a spring; if the oil pressure does not reach the preset pressure value during the oil injection period, The oil pump continues to operate until the end of the oiling period, the microprocessor controls the oil pump to stop. Therefore, the power saving method of the oil injection system can prevent the oil injection equipment from being in a high voltage state for a long time, achieve the power saving effect, and extend the service life of the equipment.

FIG. 1 is a schematic diagram of a lubricating oil injection system used in a preferred embodiment of the present invention.

The technical content and features of the present invention will be described in detail through a preferred embodiment in conjunction with the drawings. Since the power saving method of the lubricating oil injection system of the present invention can be applied to different lubricating oil injection systems, the application of the present invention will be described first. The structure of the lubricating oil injection system, please refer to FIG. 1 first, which is a lubricating oil injection system 1 used in a preferred embodiment of the present invention. The lubricating oil injection system 1 includes an electric injection Oil engine 10, a filter 20, a diverter joint 60, a first distributor 30, a second distributor 40, a pressure detector 50, two oil pipelines 16, 26, and two oil inlet pipes 36, 46.

The electric oiler 10 has an oil tank 12 for storing lubricating oil, a microprocessor 14 is disposed on the oil tank 12, an oil pump (not shown) is located in the oil tank 12 and is electrically connected with the microprocessor 14, An alarm (not shown) is provided on the oil tank 12 and is electrically connected to the microprocessor 14, and an oil outlet 15 is connected to the oil pump, and the oil outlet 15 is connected to one end of the oil pipeline 16. The microprocessor 14 is electrically connected to the pressure detector 50. The microprocessor 14 can receive the signal of the pressure detector 50 and control the operation of the oil pump and the alarm, whereby the microprocessor 14 When the oil pump is controlled to start, the oil pump can draw the lubricating oil in the oil tank 12 and output it to the oil pipeline 16 through the oil outlet 15, and the microprocessor 14 can control the alarm to emit sound, light or vibration alarms.

The filter 20 is disposed between the oil transfer pipe 16 and the oil transfer pipe 26 to filter the lubricating oil passing therethrough.

The diverter joint 60 is a three-way joint, and diverts the lubricating oil from the oil transfer pipe 26 to the two oil inlet pipes 36 and 46.

The first distributor 30 is a volumetric distributor. The first distributor 30 includes an oil inlet 33 connected to one end of the oil inlet pipe 36 and five interconnecting distribution units 32. The distribution units 32 communicate with each other. Each of the distribution units 32 includes a receiving chamber (not shown), a reciprocating piston (not shown) is located in the receiving chamber, and an oil outlet 35 communicates with the receiving chamber. Port 35 is connected to an oil outlet pipe 38. When the oil pump is started, lubricating oil is injected into the first distributor 30 through the oil inlet 33. The oil pressure forces each piston of the distribution unit 32 to move backward. When the oil pressure reaches a When the pressure value is preset, a predetermined volume of lubricating oil is stored in the storage chamber of each of the distribution units 32. When the oil pump stops operating and the oil pressure drops, The piston of each distribution unit 32 is moved back to its original position by a spring (not shown), and the lubricant of the preset capacity can be transported outwards through the oil outlet 35 and the oil outlet pipe 38 to each of the required lubrication. Place.

The second distributor 40 and the first distributor 30 have substantially the same structure, and the difference lies in the number of distribution units. The second distributor 40 includes an oil inlet 43 connected to one end of the oil inlet pipe 46, and three distribution units 42. Each of the distribution units 42 includes a container (not shown), a piston (not shown), and an oil outlet 45. Each of the oil outlets 45 is connected to an oil outlet pipe 48, and its operation mode is similar to that of the oil outlet pipe 48. The first distributor is the same.

The pressure detector 50 is disposed on the second distributor 40 and can sense the oil pressure in the volume of one of the distribution units 42. When the oil pressure reaches a preset pressure value, the pressure detector 50 sends out A message is sent to the microprocessor 14, which controls the oil pump to stop. It should be noted that the preset pressure value is determined according to the design of the distributor. When the preset pressure value is reached, the piston of the distributor is pushed to the limit, that is, the chamber is filled with lubricating oil. Based on Pascal's principle, the pressure at any point in the closed container is the same, so the oil pressure in the chamber of the second distributor 40 and any of the inlet pipes 36, 46, the oil pipeline 16, 26 and the first distributor 30 The oil pressure is the same, so the pressure detector 50 can also be set at any of the above positions.

The power saving method of the lubricating oil injection system of the present invention includes the following steps: First, in step (A), the user sets a fuel injection period and an intermittent period in the microprocessor 14, and the oil injection period and the intermittent period constitute a cycle. For example: the oil injection period is 3.5 hours, and the intermittent period is 2.5 hours, so the entire cycle is 6 hours; or the oil injection period is from 12 midnight to 12 noon, and the intermittent period is 12 noon to 12 midnight, The entire cycle is one day.

Next, in step (B), when the oil injection period starts, the microprocessor 14 controls the oil pump to start, and the oil pump injects lubricating oil from the oil inlet pipes 36 and 46 to the first distributor 30 and the second Minute In the container of the distributor 40, at the same time, the pressure detector 50 measures the oil pressure in the container of a distribution unit 42 in the second distributor 40 and transmits the information of the oil pressure to the microprocessor 14. .

Then, step (C) is entered. If the information received by the microprocessor 14 during the oil injection period indicates that the oil pressure does not reach the preset pressure value, the oil pump continues to operate. If the information received by the microprocessor 14 indicates that the oil pressure has reached the preset pressure value, the information received by the microprocessor 14 still displays after a predetermined delay period (such as 3 minutes) has passed by the microprocessor 14 If the oil pressure is greater than or equal to the preset pressure value, the microprocessor 14 controls the oil pump to stop. At this time, the oil pressure in the two oil inlet pipes 36 and 46 drops and is stored in the first distributor 30 and the second The lubricating oil in the distributor 40 is output through the oil outlet pipes 38, 48; if the information received by the microprocessor 14 before the end of the delay period shows that the oil pressure is less than the preset pressure value, it means that the oil pressure has not yet reached steadily At the preset pressure value, the oil pump continues to operate. It should be noted that the purpose of setting the delay period is to ensure that the oil pressure is stable and sufficient, and the length of time is set based on experience. If the oil pressure has not reached the preset pressure value at the end of the fueling period, the microprocessor 14 controls the oil pump to stop operation because it has entered the intermittent period. At this time, the first distributor 30 and the second distributor 40 does not output the lubricating oil stored in the container, and the microprocessor 14 can control the alarm to issue an alarm.

During the intermittent period, the oil pump does not operate until the end of the intermittent period and the filling period starts, the microprocessor 14 controls the oil pump to start, and repeats the above steps (B) and (C) cyclically.

With the power saving method of the lubricating oil injection system provided by the present invention, when the oil pressure in the oil pipe or the content chamber of the distributor reaches a preset pressure value, it indicates that the working pressure required by the distributor has been reached, and the microprocessor immediately or slightly Controlling the oil pump later (after the delay period) can prevent the oil injection system from staying in a high oil pressure state for a long time, which can not only save electricity, but also extend the service life of equipment such as oil pipes and distributors, thereby achieving the purpose of cost invention.

In other embodiments, after the delay period, the microprocessor 14 may directly control the oil pump to stop operation without comparing whether the oil pressure is greater than or equal to the preset pressure value. Once the oil pressure reaches the preset pressure value, it will not drop; or the delay period may not be set, that is, when the oil pressure reaches the preset pressure value, the microprocessor 14 immediately controls the oil pump to stop. This can also achieve the purpose of the invention.

Based on the spirit of the present invention, different pressure detectors can be used. For example, an analog pressure detector such as a pressure switch can be used. No signal is output when the measured pressure does not reach the preset pressure value. When the pressure value is set, a signal is output; or a digital pressure detector can be used to measure the pressure and transmit the measured value to the microprocessor 14, and the microprocessor 14 can compare the measurement Value and the preset pressure value to determine whether the oil pressure reaches the preset pressure value.

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 oil injection system 1 may not be provided with the alarm, the filter 20 and the split joint 60, and the number of the distributor and The number of distribution units in each distributor can be changed. The pressure detector 50 and the microprocessor 14 can transmit signals wirelessly, that is, regardless of their structure, the power saving method of the oil injection system of the present invention can be applied. The structure of the oil injection system cannot be used to limit the patent scope of the present invention.

The above is only a description of the embodiments of the present invention, and cannot be used to limit the patent scope of the present invention. For example, any simple structural decoration or change that does not exceed the spirit of the present invention should still be covered by the patent scope of the present invention.
