[Embodiment] As shown in FIG. 4, the battery 5 5 provides a power source 5 5 i to the low voltage detecting circuit 587 and the control circuit 517. The control circuit 57 is a programmable logic IC, and the power source 5 5提供 A low voltage detection circuit 587 provides a power to the control circuit 5 7 i, the control circuit 5 7 output: the start signal to the air pump 5 2, so that its motor starts, and beats the inhalation action, as shown in the figure As shown in the second, the outside air is drawn into the tank 5 i from the air inlet hole 6, and the air in the tank 5 is continuously input into the air outlet 4 through the air duct 5, and the air is continuously discharged. The air hole 4 2 is introduced into the upper airtight chamber 121, so that the air pressure of the upper airtight chamber 121 is increased, and the horizontal displacement of the piston 20 is pushed downward. Due to the design of the air second steam ring 29, 28, the upper airtight chamber 121 is made. The gas in the gas is not shallow and acts on the piston 2〇 with the average air pressure. Therefore, the oil pressure of the top oil pressure tank 32008 is shifted downwards, and the air pressure in the upper airtight chamber 1 2 1 is large enough to control the piston 2 〇 and the oil pack 3 〇 the distance moved downwards 'further to control the grease 9 〇 from the lower exit 1 2 5 Out of the flow and velocity. When the piston 2 移位 is displaced downward to reduce the volume of the oil pocket 3 〇, the space in the lower groove to the 1-2 is also gradually reduced, and the air in the lower chamber 1 2 2 is taken from the vent hole 16 Extrude the body 1 〇 outside. As shown in Fig. 2 and Fig. 6, the grease 9 is an industrial lubricating oil, which is input into the lubricated component 经 via the pipe 95, and the lubricated component 丄〇〇 can be a bearing; the second sensing line 5 7 3 /, 5 7 5 / The detection terminals are connected to the 70 pieces of 1〇Q that are lubricated and the sensing line 5 7 3 ' 5 7 5 / is transmitted through the terminal jacks 6 1、.1, 6 0 2 and the audio sensing line 5 7 3 and the temperature sensing line 5 7 5 are connected, so the sound frequency of the lubricated component 1 is detected by the audio sensor 574, such as the part of the lubricated component 100 (such as a steel ball). When the rupture is damaged, the abnormal sound frequency generated is greatly different from the normal working audio. When the abnormal audio is detected by the audio sensor 574, the abnormal signal is processed through the control circuit 57. And the processed signal is not displayed on the LED screen 64 in words or patterns, and the abnormal signal is also transmitted through the radio wave transmitter 7 (as shown in Figure 5), and is located at the remote wireless The radio wave receiver 7 receives the signal, and the received signal is sent to the computer host 7 6 for processing, and will be The following signal is supplied to 1 buzzer 7 7 response 2 warning light 7 9 flashing red light 3 and computer host 7 6 connected display 7 8 shows the damaged element 1 q 〇 damaged or abnormal text or pattern ° control circuit 5 7 1 does not output voltage signal to the line pump 5 2 11 200809128 'Air pump 5 2 stops working. As shown in Fig. 6, when the operating temperature of the lubricated element i 0 太 is too high, for example, when the bearing is rotated too fast, the temperature thereof is inevitably greatly increased, and the lubricating element 100 does not work smoothly (such as the rotating interface friction force). When it is large, it is possible to raise the temperature of the lubricated element 100, which is measured by the temperature sensor 5 7 2 through the temperature sensing line 5 7 5 and outputs a signal of abnormal temperature. The control circuit 517 is processed, and the processed signal is displayed in text or pattern on the [ED screen 64. Similarly, the text or pattern is also displayed on the remote display 78, and similarly. The buzzer 7 7 response and warning light 7 9 lights up, and the air pump 5 2 stops operating. When the internal passage of the lubricated element 1 is blocked or the pipeline is blocked by the pipe 9 5, the oil pack 30 cannot reproduce the output grease 9 〇, and the oil pack 3 〇 and the piston 2 停 are all parked (as shown in Figure 2). However, the air pump 5 2 is still pumping the outer jade gas into the upper air chamber 1 2 1 , and the air pressure in the upper airtight chamber 1 2 1 will become higher and higher, causing the air pump 5 2 to use its motor. When the working current value increases to a certain value, it is detected by the current detecting circuit 8 8 , and the abnormal signal is output to the control circuit 5 7 1 for processing, and the control circuit 5 7 1 no longer outputs the voltage signal air pump. 5 2, the air pump 5 2 stops working, and the abnormal signal is processed by the control circuit 5 7丄, the KLED screen 64 is displayed in text or pattern, and the radio wave transmitter is transmitted to the far-end radio wave receiver by the radio wave transmitter 70. 7 5 to receive the processing, according to the above principle, the buzzer 7 7 sounds, the warning light γ 9 flashes and the display 7 8 shows the text or pattern blocked by the pipeline 9 5 or the lubricated element 1 2008 12 200809128 passage. When the battery 5 5 is too low, the low voltage of the output is detected by the low voltage detecting circuit 587, and a signal is output to the control circuit for processing. At this time, according to the foregoing principle, the LED screen 6 4 The text or pattern of "Low Power" will be displayed, and the buzzer will sound 7 7 and the warning light 7 9 will flash. The display will show the text or pattern of "low power". The user has to get from the LED screen. 6 4, the warning light 7 9 flashes, the buzzer 7 7 response and the remote display 7 8 shows the gas pressure control device of the case 'what is wrong, and the problem needs to be solved. When the oil bag 3 0 When it is used, the user unscrews the lower thread sleeve 1 5, and the lower thread sleeve 15 is separated from the body 1 ,, so that only a small amount of grease 10 can be taken out, and a new oil pack is replaced. 3 〇, but at this time there is air pressure in the upper airtight chamber 1 2 1 , so the piston 2 〇 can not be pushed up, as shown in Figure 4, the user presses the skateboard with a finger or a tool 2 5 3 , spring 2 6 6 In a contracted state, the valve 25 is raised and opened by a passage 2 5 1, so that the air is discharged from the passage 2 5 , and then live 2 〇 可 can be easily pushed up to facilitate the installation of the new oil package 3 ( (as shown in Figure 1), the button 6 5 can be set by the user temperature sensor 5 7 2 its temperature setting and air The time period of the start of the pump 5 2 is suppressed. The set value can be displayed by the near-end LED screen 64 and the remote display 7 8 . The oil pack 3 〇 has the V-shaped protrusion 3 1 and the recess 3 2 Therefore, the entire oil pack 30 is in a state of being compressible and deformable, so that when the oil pack 30 is pressed down to the bottom dead center by the piston 20, the oil of the oil pack 3 几乎 is almost completely output. 13 200809128 [Simple diagram The first figure is an exploded perspective view of the present invention.
