Automatic bagging machine for mineral powder

"Easy installation" is the characteristic of ball presses, but the humanized design of different brands of ball presses is still uneven. Many international famous brands provide humanized procts, but also have a set of instant and effective installation, debugging, troubleshooting solutions. Here, the common precautions and effective methods of troubleshooting in practical engineering are briefly put forward. Only the correct installation and proper maintenance can make the ball press play its e brilliance
installation of the ball press
before installing the ball press, the pipelines should be laid in strict accordance with the electrical specifications, and the strong current and weak current signal lines should be isolated and laid to avoid interference. In outdoor open environment, independent external lightning protection measures should be taken. The ball machine itself should also be well grounded to prevent the accumulation of static electricity on the ball machine. During installation, the power line, communication line and video line should be correctly connected, and the requirements of installation instructions should be carefully referred to when connecting to confirm the communication mode and corresponding pin definition. Generally, the equipment should be installed in the later stage of construction to avoid a large amount of st intrusion into the ball machine at the construction site, which directly affects its use effect and service life
in addition, the following precautions should be paid extra attention
note 1: power supply
in order to ensure the normal operation of the ball press, the power supply should not be lower than the nominal value of the ball press input voltage. When the nominal value is 24 VAC, the voltage fluctuation should not exceed ± 25% The common working voltage of ball machine is 24 vac. At present, there are 220 VAC ball machines on the market. In essence, the transformer is built into the ball cover to supply power to the ball machine after voltage transformation. The separation of strong current and weak current should be emphasized in wiring to avoid the interference of strong current to weak current. The internal space of the ball machine is limited, and the built-in transformer makes the strong and weak current coexist, thus affecting the weak current signal. In addition, the built-in transformer will increase the heat dissipation burden, thus increasing the possibility of burning out the built-in circuit. According to the different site environment, you can choose local 220 VAC to 24 VAC, or remote transformer, centralized power supply mode. When centralized power supply, the loss of electric energy caused by transmission line should be fully considered. Select the equipment with larger output power and increase the output voltage appropriately to carry the line voltage drop, such as 28VAC output to power the remote ball machine
is there enough power for the ball press? It can pass the multimeter test. The method is to use the multimeter to measure the voltage of the power line at one end of the ball machine when the load (ball machine) is on, and observe whether the voltage is within the allowable range of the ball machine. In particular, it should be noted that the power consumed by the outdoor ball machine is quite different when the heater is started or stopped. When supplying power to the outdoor ball machine, the maximum power required by the ball machine in the worst environment must be considered. When the fluctuation of mains voltage exceeds the range of + 5% ～ - 10%, AC voltage stabilizing device shall be set. UPS can be installed to provide uninterrupted power supply
note 2: grounding
the grounding of ball press is mainly divided into shell grounding and internal electrical grounding. The shell grounding is mainly used to prevent the accumulation of static electricity, electric leakage, etc. the outdoor ball machine should also be equipped with external lightning protection measures. Generally speaking, the shell of outdoor ball machine installed on the vertical pole support has naturally formed grounding protection because it is screwed on the metal support, so special treatment is not needed. The data line and video line inside the ball machine have been grounded. Connect the GND end inside the ball machine with the ground wire to ensure the effective grounding of the equipment
note 3: the ground loop circuit
even if the equipment is effectively grounded, there are differences in the zero potential of different positions between the ball machine and the central equipment, and the power load is unbalanced, which will still cause the ground potential difference. The potential difference generates current through the closed circuit formed by coaxial cable, which causes interference and affects the normal transmission of video signal. It is usually shown as the clutter in the horizontal direction in the middle of the image. The most effective way to solve the problem of ground loop is to add ground loop isolator in video transmission. At present, most of the video signals of indoor / outdoor ball loader are still transmitted by coaxial cable, and some ball loaders are far away from the central equipment, so it is easy to form ground loop. If optical transceiver is used for signal transmission, the influence of ground loop can be avoided effectively
note 4: Waterproof
the installation of outdoor ball press must be waterproof. For the suspended installation, there is a gap between the ball machine and the bracket. In case of rain and snow, water will penetrate into the interior along the gap, causing harm. Therefore, waterproof and sealing measures should be taken ring the installation to prevent rainwater from entering the ball machine from the screw interface. The selection of installation support is also very important, and the original support is recommended. The original support fully considered the waterproof problem, such as the inclination design to make the ball machine spin end slightly higher. Even if there is water in the support, it will only flow back into the column, not into the ball machine. Therefore, if the user makes the bracket by himself, the waterproof factor should be fully considered. Why are there water droplets in the stent? Generally speaking, the temperature is higher in the daytime, and the water vapor in the vertical pole enters the support. When the temperature drops at night, the water vapor will condense into water droplets and condense along the support wall. When the support is not inclined or tilted in the opposite direction, water droplets will flow into the ball machine along the wall, causing harm. In order to rece the water vapor entering into the support, the joint between the support and the vertical pole can be sealed with rubber paste or silica gel
note 5: heat dissipation
the heat dissipation problem of the ball press must also be considered. There is no outdoor model for some brands of ball machines on the market, so they can not be directly used outdoors, so they must be equipped with outdoor shield and other accessories. PELCO outdoor ball machine standard includes sunshade, heater, double cooling fan and other elements, so that it can adapt to outdoor harsh or extreme temperature difference environment
equipment debugging
after the installation of each ball press, the indivial debugging should be carried out first, which can rece the burden of the whole system debugging. The ball machine of PELCO provides RJ45 interface for unit debugging. Through RJ45 interface, the ball machine can be connected with the debugging kit to debug the output image, pan tilt rotation and lens stretching of the ball machine. You can also enter the ball machine menu for further initial settings

"GEC environmental protection coin" is suspected of pyramid selling, which is deceptive

"GEC environmental protection coin" trading mode has been widely spread, which takes "ecological environment protection", "zero investment", "zero risk" and "high income" as labels, and draws people into the partnership to pull down the development capital chain. Instry experts pointed out that the environmental protection coin can basically be classified as a circle. The appearance of disk circle is virtual currency, and the core is capital disk. The former's income comes from the later's capital. This model is not only suspected of ICO in disguise, but also suspected of MLM

extended information:

"GEC environmental protection coin" is obviously in line with the nature of pyramid scheme

one is to solicit customers with extremely high returns and declare that they only go up but not down, which has great attraction to investors

the second is to build the head MLM framework, build the membership mode, and realize the viral sales of GEC
