Yesterday, a number of WeChat account operators reported to reporters that at noon yesterday, more than 12:00 and more than 13:00, multiple login WeChat public number back-end Web version, there is a "page does not exist" words. The rumor has been that due to a large number of articles in public articles, the fault was caused by the WeChat server's background crash.
"More than two in the afternoon, the WeChat public number back to normal." The editor Xiao Zhang, who runs the public account of a large newspaper company, told reporters that unlike the network dropped, yesterday's more than an hour of continuous login is not on the WeChat public account. It may be a server crash. The reporter also saw many public account operators in a number of WeChat groups, saying that the public number was inexplicably backstage.
With regard to the failure of the public number, it is generally feared that the amount of brush reading and the amount of praise affect the WeChat ecology. The Tencent side denied it, saying it was due to server upgrades that caused some of the public numbers to fail to get onto the backstage.
It is understood that on the evening of July 24th, the WeChat grayscale test public account reading frequency display and like-like function, this function has been reflected in some WeChat public accounts. Although the WeChat public account reading frequency display and like function are still in the test period, they have detonated time bombs in the areas of self-media and public numbers with marketing functions, and have also fostered merchants operating WeChat promotion and marketing titles to run concurrent WeChat brushes. Powder, forwarding business.
In this regard, Chen Lei, general manager of the cloud platform division of Tencent, said that Tencent has responded to these cheating methods with corresponding technical measures. He said that one of the anti-brushing techniques is a check code, which is used to counteract the behavior of the check code and brushing fake data.
Micro motors Based on Dc Motor, micro motor belongs to the small size of dc motor,micro motor rotor, back cover, chassis, rotor winding is mainly copper, back cover most of the use of plastic material, motor shell use galvanized steel plate, the micro motor can be ROHS test.
A micro motor is any of a class of rotary electrical machines that converts direct current electrical energy into mechanical energy. The most common types rely on the forces produced by magnetic fields. Nearly all types of micro motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current flow in part of the motor.
Micro motor is mainly used in: outdoor lamps, electronic toys, model aircraft, intelligent bin, breeze machine, etc
Method of use: the best stable in horizontal plane, installed on the Micro motor output shaft parts, cannot use a hammer to knock, knock prone to press into the micro motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
Micro motor should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a micro motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
Micro motor should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
The longevity of micro motor is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.
â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
