Modern 4g cat gps tracking is very different in principle and structure, how to select 4g cat gps tracking reasonably according to the specific measurement purpose, measurement object and measurement environment, is the first problem to be solved when conducting a certain amount of measurement. When the 4g cat gps tracking is determined, the corresponding measurement method and measurement equipment can be determined. The success or failure of the measurement results largely depends on whether the selection of 4g cat gps tracking is reasonable.

1. Frequency response characteristics:

The frequency response characteristic of 4g cat gps tracking determines the frequency range to be measured, and the measurement conditions must be maintained within the allowed frequency range. In fact, the response of the sensor always has a fixed delay, and it is hoped that the delay time is as short as possible. The frequency response of the sensor is high, and the frequency range of the measurable signal is wide, while the inertia of the mechanical system is large due to the influence of the structural characteristics, and the frequency of the measurable signal is low because of the sensor with low frequency. In dynamic measurement, the response characteristics should be based on the characteristics of the signal (steady state, transient, random, etc.) to avoid excessive error.

2, linear range:

The linear range of 4g cat gps tracking refers to the range where the output is proportional to the input. In theory, within this range, the sensitivity remains constant. The wider the linear range of the sensor, the larger its range, and can ensure a certain measurement accuracy. When selecting a sensor, when the type of sensor is determined, it is first necessary to see whether its range meets the requirements.

3, according to the measurement object and measurement environment to determine the type of sensor:

To carry out a specific measurement work, we must first consider what principle 4g cat gps tracking is used, which needs to be determined after analyzing many factors. Because, even if the measurement of the same physical quantity, there are a variety of principles of the sensor is available, which principle of the sensor is more suitable, you need to consider the following specific problems according to the characteristics of the measurement and the use of the sensor conditions: the size of the range; The sensor volume requirements of the measured position; Whether the measurement mode is contact or non-contact; Signal extraction method, wired or non-contact measurement; The source of the sensor, domestic or imported, whether the price can be borne, or self-developed.

4, the choice of sensitivity:

In general, in the linear range of 4g cat gps tracking, you want the sensitivity of the sensor to be as high as possible. Because only when the sensitivity is high, the value of the output signal corresponding to the measured change is relatively large, which is conducive to signal processing. However, it should be noted that the sensitivity of the sensor is high, and external noise unrelated to the measurement is easy to mix, and will also be amplified by the amplification system, affecting the measurement accuracy. Therefore, it is required that the sensor itself should have a high signal-to-noise ratio to reduce the factory interference signal introduced from the outside world.

5, accuracy:

Accuracy is an important performance pointer of 4g cat gps tracking, and it is an important link related to the measurement accuracy of the whole measurement system. The higher the accuracy of the sensor, the more expensive its price, therefore, the accuracy of the sensor as long as it meets the accuracy requirements of the entire measurement system, it is not necessary to choose too high. In this way, a cheaper and simpler sensor can be selected from many sensors that meet the same measurement purpose.

6. Stability:

The ability of 4g cat gps tracking to remain unchanged in performance over a period of time is called stability. In addition to the structure of the sensor itself, the main factor affecting the long-term stability of the sensor is the use environment of the sensor. Before selecting a sensor, the environment for its use should be investigated, and the appropriate sensor should be selected according to the specific use environment, or appropriate measures should be taken to reduce the environmental impact. The stability of the sensor has quantitative indicators, and after exceeding the use period, it should be re-calibrated before use to determine whether the performance of the sensor has changed.

application of central dust collector has the characteristics of high cleaning effect and is generally valued. Over the decades, the application of central dust collector has developed rapidly, with more and more applications, and the size and category specifications are also compared. The dust collector generally adopts a round bag, which is divided into two forms according to the direction of dust bearing air flow: side inlet air, down inlet air, two forms. This dust collector is usually composed of the upper box, the middle box, the ash hopper, the frame and the pulse blowing device. When the dust bearing gas enters the ash hopper from the lower part of the box, the dust collector can be used to collect dust. Due to the sudden expansion of the air flow area and the decrease of the flow rate, a part of the air flow with coarse particles and dense dust particles settle down in the ash bucket under the action of gravity. After the dust particles with fine particle size and small density enter the filter bag room, the dust is deposited on the surface of the filter bag through the inertial collision on the surface of the filter bag, screening and other comprehensive effects, and the purified gas enters the clean gas chamber and is removed by the exhaust pipe through the fan.

Here, explain the application of central dust collector main control device installation knowledge:

First, the compressor is connected, and then the soft connection is connected to the gas storage tank of the single application of central dust collector.

The bolts of the manufacturer's products should be tightened to avoid air leakage of the equipment. When installing the filter cartridge, the corresponding installation should be stable and there is no shaking.

Third, before installing the main control device of the application of central dust collector, all the corresponding checks should be carried out. Only all parts can be installed if there is no problem. If one part is damaged, it must be repaired before installation.

When lifting the application of central dust collector, do not touch the equipment and parts accordingly. The irrigation hole should not be larger than the equipment.

application of central dust collector Compressed air is used in the pulse jet cleaning process, and the compressed air is itself saturated air with 100% relative humidity. Because its pressure is greater than atmospheric pressure, the dew point converted to atmospheric pressure is lower than the ambient dew point, and there is a tendency to break away from condensation. When the compressed air temperature is not much different from the flue gas temperature inside the dust collector, condensation is generally not produced. However, in winter, when the winter temperature in the north of China is usually ten or dozens of degrees below zero, the compressed air sprayed by the pulse and the flue gas temperature inside the dust collector is too large, and the temperature also drops sharply when the compressed air is sprayed into the filter bag instantaneously, usually a white mist spray of condensed water mist, the temperature within the corresponding distance below the nozzle is low, forming a low temperature area. Since the compressed air in the nozzle is saturated air, the temperature drop after the gas ejection will lead to the precipitation of water in the area and cause condensation. At this time, the condensation is mainly concentrated on the surface of the blown filter bag, and the dust adhering to the surface of the filter bag is bonded by absorbing the moisture precipitated by condensation, and then blocking the porosity of the dust filter bag, resulting in the dust collector can not work normally.

Only by doing a good job of daily maintenance, mid-speed wire cutting machine supply will improve its service life and bring more results. So how to do the maintenance of equipment? The first is the individual systems of the equipment, a series of systems need to be checked in accordance with the normal operation of the program. If in the process of detection, there is an abnormal operation, then the equipment should be stopped. And in the later period of time technicians to repair, to ensure the normal use of equipment.

The above is a daily inspection to check whether the operation of each equipment is normal. Next is the weekly inspection, most of which is focused on the parts. Because after a period of time, on the machine tool, more or less there will be some iron filings left after processing, then you need staff to clean up these residues well to ensure the normal work of the machine tool. The second is the monthly inspection, mainly for the power supply and air desiccant. Choose a good place to ensure that the operator and the machine can work in the best environment. If the power supply is abnormal, then the staff needs to adjust in time to avoid some unnecessary things and add trouble. As for the air dryer, it is necessary for the worker to clean it after a period of time, and then use it in installation.

In the quarterly inspection is still based on the bed, because the higher the precision of the mid-speed wire cutting machine supply, then the level of the machine tool can meet the relevant requirements, and the product can be used after the most. So if it is not in the scope of the provisions, then it should be checked in time, when necessary, please professional maintenance technicians to come to repair. There is also the appropriate replacement of new oil on the spindle, cleaning is also necessary. Finally, it is for several different important systems of the machine tool, the corresponding detailed inspection. For these major systems, if there is a problem, it will greatly affect the production efficiency. At this time, the cleaning should be cleaned, the oil should be changed. Or check with a professional mechanic, so that problems can be solved in the best time.
