Application of PLC-based E-Drive inverter on bag filter?
Brief introduction: Bag filter is a dry dust filter device. After using the filter media for a period of time, due to the effect of sieving, collision, retention, bag filter diffusion and electrostatic, a layer of dust accumulates on the surface of the filter bag, this layer of dust is called the primary layer, in the process of movement thereafter, the primary layer becomes the main filter layer of the filter media, relying on the role of the primary layer, the filter media with larger mesh can also obtain a higher filtration efficiency. With the accumulation of dust on the surface of the filter media, the efficiency and resistance of the dust collector increase accordingly. When the pressure difference between the two sides of the filter media is large, some fine dust particles that have been attached to the filter media will be squeezed over, so that the efficiency of the dust collector decreases. In addition, the high resistance of the dust collector will make the air volume of the dust removal system drop significantly. Therefore, after the resistance of the dust collector reaches a certain value, it should be cleared in time. When cleaning ash, the initial layer should not be destroyed, so that the efficiency will not drop. Process flow: The soot generated in the electrostatic furnace passes through the duct under the wind pressure of the fan and enters the dust collector. The dust collector is mainly composed of N dust removal chambers. The purification of the flue gas is achieved by sequentially controlling the N dust chamber inlet valve and the back-suction valve off \ break as well as the mechanical shock beating. The purified flue gas is discharged into the atmosphere through the chimney, while the dust is adsorbed by the filter bag and collected in the ash discharge bin, which is discharged to the ash discharge pipe through the control of the discharger, and then the ash is sent to the encryption bin by the fan, or the dust is sent to the encryption bin by manual or mechanical means. Eventually the dust inside the bin is collected manually from the lower end of the encrypted bin with a cloth bag and transported to the treatment plant. High temperature flue gas purification is carried out on site using bag filter. Considering the actual performance of the equipment, the allowable temperature of the filter bag is about 100℃, which is very different from the high temperature flue gas temperature (generally up to 300℃), so the high temperature flue gas must first be cooled down and the cooling process must be monitored in real time. The specific method is: a temperature sensor is installed at the front and rear of the suction pipe to detect the flue gas temperature at the suction port and at the entrance of the bag filter respectively; an electric butterfly valve is installed in the middle of the pipe, when the temperature detected by the two temperature sensors exceeds the set value, the electric butterfly valve opens to mix in a certain...

    Why is the PLC made so flat?
    With the continuous reduction of PLC price and the expansion of user demand, more and more small and medium-sized equipment began to choose PLC for control, the application of PLC in China is growing very rapidly. With the rapid development of China's economy and the continuous improvement of the level of domestic automation, PLC in China in the coming period will still adhere to the momentum of rapid growth. Today's PLC products can be divided into three main schools: the United States, Europe and the mouth of this. With the rapid development of China's PLC, the domestic PLC occupies more and more weight. According to statistics, more than 95% of the failure rate of these PLC products appear in the power supply, relays, communication port these places. So how to reduce the failure rate of these places Gu Mei PLC made these changes Power supply external to eliminate 90% of the failure Prevent air temperature changes, humidity changes under the influence of air, dust, ultraviolet light and other factors to damage the equipment. The most prone to failure is generally in the power supply system and communication network system, the power supply in the continuous work, heat dissipation, voltage and current fluctuations in the impact is inevitable. Communication and network by the possibility of external interference, the external environment is one of the biggest factors causing the failure of communication external equipment. At present, the PLC on the market is basically a power supply built-in, while our products use external power supply to eliminate 90% of the failures. Relays with one of the best brands - Omron Business cost control of PLC, selection are dependent on the I/O, I/O module is an important part of the PLC. the PLC's biggest weak link in the I/O port. the technical advantage of the PLC is its I/O port, in the case of the host system's technical level of the difference between no machine, the I/O module is the key component that reflects the performance of the PLC, so it is also a prominent link in the PLC damage. The relay used by Gumei is Omron, one of the world's top ten brands. Communication port special protection RS-232 interface data transmission rate is low, the transmission distance is limited, and the anti-interference ability is poor. RS-422 adopts full-duplex communication mode with differential transmission, and the anticommon mode interference ability is enhanced. GuMei used the 485 port, 485 port than 232 port voltage resistance is high, not easy to burn out. Through these methods, the failure rate of PLC is greatly reduced, and PLC volume is more compact but better performance, these applications in the customer always also get the customer's approval.

    Application of V-Control PLC and HMI on pipe cutting machine
    Brief introduction Tube cutting machine is a special equipment used to press and cut all kinds of common cardboard, corrugated cardboard, plastic sheet and leather products. It is suitable for printing, packaging and decoration, plastic and other industries. It has the advantages of compact structure, excellent manufacturing, high pressure cutting force, high precision, easy to use, safe and reliable operation, etc. Process requirements Fully automatic mode, using the 3VE's flying shear function, input the length that needs to be cut, and require the error of each cut out tube to be within 5 silk. Program The control system mainly uses the V-Control HMI LEVI-700LK, PLC host using LX3VE-1412MT, servo using position control mode. The brief scheme is as follows: input the length to be cut on the touch screen, set the output, input the number of pulses for one turn of the master and slave axis respectively, and the perimeter of the master and slave axis, etc., click on the parameters to determine, then click on the start, and you can work. Project summary 1, for the sensor position judgment. 2, because the sensor is in front of the nozzle arm, so you need to determine whether it is in the front half or the back half, you need to go through the distance between the sensor and the nozzle arm before rising and falling. 3, the power-on self-test operation, each time the power on should first determine whether the sensor is working properly, the position is right to run.
