The method can iron out the defects in the prior art that an electronic element is liable to be aged, is low in working reliability and is difficult to maintain, so as to achieve the advantages that the electronic element is not liable to be aged, is high in working reliability and is easy to maintain.
Description
Technical field
The present invention relates to cement processing technique field, particularly, relate to a kind of method shortening Bag Making Machine fault time.
Background technology
Dragging direct current machine is that DC controller controls, and because DC controller ran more than 19 years, electronic component serious aging on controller, functional reliability significantly declines.We are according to the logging of electrical service and producers, and it is as follows to carry out statistics the downtime caused various fault:
Table 1: bag drags direct current machine fault statistics table
According to upper table, cause bag to drag direct current machine fault and carried out classifying summing up, see the following form:
Table 2: bag drags direct current machine fault inductive statistics table
| Classification | Fault time | Percentage | Cumulative percentage |
| Control system causes fault time | 24.5 | 61.6％ | 61.6％ |
| The fault time that misoperation causes | 8.2 | 20.6％ | 83.2％ |
| The fault time of release-locking device | 3.8 | 9.6％ | 91.8％ |
| Other fault times | 3.3 | 8.2％ | 100％ |
From causing bag to drag direct current machine failure factor, want to shorten fault time, the fault time that must cause from control system starts with.
Realizing in process of the present invention, inventor finds at least to exist in prior art electronic component easily aging, the defect such as functional reliability is low and maintenance difficulties is large.
Summary of the invention
The object of the invention is to, for the problems referred to above, propose a kind of method shortening Bag Making Machine fault time, to realize electronic component not easily aging, functional reliability is high and maintenance difficulties is little advantage.

(1) the control structure of optimal controller;
(2) increase heat abstractor to motor, the working method of motor is revised as paired working method in turn.
Further, step (1) in, the control structure of the controller after optimization, comprises the power supply, frequency converter and the motor that connect successively, and the speed regulator, start button and the control switch that are connected with frequency converter respectively.
Further, described frequency converter, specifically comprises Delta VFD Series Frequency Converter.
Further, described motor, specifically comprises as squirrel-cage motor Y160L-4.
Further, described speed regulator, specifically comprises 0-5 kilo-ohm of potentiometer.
The method of shortening Bag Making Machine fault time of various embodiments of the present invention, owing to comprising: the (1) control structure of optimal controller; (2) increase heat abstractor to motor, the working method of motor is revised as paired working method in turn; Thus easily aging, functional reliability is low and maintenance difficulties the is large defect of electronic component in prior art can be overcome, to realize electronic component not easily aging, functional reliability is high and maintenance difficulties is little advantage.
Other features and advantages of the present invention will be set forth in the following description, and, partly become apparent from specification, or understand by implementing the present invention.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Accompanying drawing explanation
Accompanying drawing is used to provide a further understanding of the present invention, and forms a part for specification, together with embodiments of the present invention for explaining the present invention, is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is that the present invention shortens improved Electric Machine Control figure in the method for Bag Making Machine fault time.
By reference to the accompanying drawings, in the embodiment of the present invention, Reference numeral is as follows:
1-speed regulator (0-5 kilo-ohm of potentiometer); 2-start-stop button; 3-control switch.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
Through investigation, in conjunction with the equipment control requirement of company, we by be determined direct current machine fault time reduce to 2 hours/month.
According to the embodiment of the present invention, as shown in Figure 1, a kind of method shortening Bag Making Machine fault time is provided.
Target is proved:
1, packaging company on average monthly produces 2,500,000, sack, because bag cutting machine is nucleus equipment, has heating system, once shut down, heating system also will stop, and sack also can scrap 20-30, causes the very large proportion of goods damageds.And along with machine stop times time more useless sack more.Whole production line bag wear rate reaches 2%, amounts to 50,000 sacks, how to shorten fault time and become the most important thing.
2, domestic advanced bag cutting machine has achieved high production efficiency, seldom has disorderly closedown.
3, tackle key problems the panelists Dou Shi department backbone of production, and have extremely abundant modification Experience.
In technical scheme of the present invention, for the defect that prior art exists, game as follows:
Such as, based on above-mentioned countermeasure, be specifically implemented as follows:
Implement one: according to control overflow and the technological requirement of original system, select and order frequency converter.
In May, panelists, according to the actual conditions of my company frequency converter used, have selected the frequency converter of Delta VFD series from the aspect such as reliability and cost performance.The features such as it is cheap, volume is little, perfect in shape and function.
Delta VFD Series Frequency Converter specific performance and parameter as follows:
This Series Frequency Converter has the control of tape speed sensor vector, speed-sensorless control, dynamic torque vector control, V/f control and various control.Overload tolerance specification 200%-3 second/150%-1 divides, and is applicable to the purposes such as fan and pump.Adopt long-life parts (designed life is 12 years, comprises main circuit capacitor, electrolytic capacitor, cooling fan)
Implement two: according to control principle drawing and Fig. 1, docked with frequency converter by former control circuit.In FIG, improved Electric Machine Control structure, comprise the power supply, frequency converter (as Delta VFD Series Frequency Converter) and the motor that connect successively (as squirrel-cage motor Y160L-4,15 kilowatts, 30.3A, 1450R/MIN), and the speed regulator be connected with frequency converter respectively (i.e. speed regulator 1 can be 0-5 kilo-ohm of potentiometer), start button (as start button 2) and control switch (as control switch 3).
