For abnormal fan operating parameters, the oil temperature upper limit alarm, the oil level lower limit alarm and the vibration upper limit alarm signal can be respectively generated, and the corresponding alarm electric contact is actuated to quickly shut down the faulty fan. The alarm value can be preset by the keyboard. The monitor also has a password lock, remote correction of measured values, and connection with the host computer. Three-parameter combination probe In the three-parameter combination probe, the acquisition of the temperature signal is performed by the semiconductor integrated sensor; the vibration signal is completed by the electric vibration speed sensor; the oil level signal is completed by the self-heating thermal resistance sensor. The connection between the monitor and the combined probe and the analysis of the working process. The connection between the monitor and the probe is from the monitor in the control room to the fan on the cooling tower. Since multiple probes are connected in parallel on the four serial busbars, short circuits should be prevented in the connections and wires. This problem is only occurred during installation and commissioning. It has occurred once due to negligible wiring, but it rarely occurs in routine maintenance. Therefore, it is recommended to check the resistance between the wires after wiring. Damage to the individual sensors may also cause false stacking of the bus signal, which increases the measured value of the normal sensor. This phenomenon is called a busy fault. Due to the high manufacturing level and high integration of the three-parameter combination probe, the reliability is good. This type of problem does not occur in long-cycle runs. According to the product requirements, the disassembly and assembly of the probe must be carried out after the power is cut off. Since the application, the probe has been disassembled several times due to other reasons, and since it has been carried out according to regulations, no damage to the system components has occurred. The level measurement of the three-parameter combination probe is achieved using a very small self-heating thermal resistance wire. In the long-term use, the dirt in the lubricating oil adheres to it, and a certain measurement deviation will occur. When the deviation is too large to be corrected by the set calibration value, the inside of the probe should be cleaned as necessary. The method is to remove the probe from the reduction box, repeatedly insert it several times in the cup with clean cleaning gasoline, and slowly lift it up for the last time. After it is fully dried, reinstall it. Since the lubricant itself is relatively clean and the monitor has a function to set the calibration value, the maintenance of such problems is not large. The KR-939B monitor has reliable performance, low cost, good flexibility, and a good user interface, in line with user operating habits. Due to the disk-mounted form, the space is small, which is especially suitable for the transformation of old devices. Luoyang Petrochemical General Plant supplies 8 sets of cooling tower fans, and 3 sets of the system are used. After long-term trials, the effect is good. In the future, 8 fans will be gradually adopted to adopt the system.
Automatic packaging machine is generally divided into semi-automatic packaging machine and automatic packaging machine. Automatic packaging machine is mainly used for automatic packaging of food, medicine, chemical industry and plant seeds. The material can be granule, tablet, liquid, powder, paste, etc. The automatic packaging machine has the functions of automatic measurement, filling, bag making, sealing, cutting, conveying, printing production batch number, increasing easy incision, warning without material, mixing, etc.
It is mainly suitable for packing instant noodles, ice cream, biscuits, Weihua biscuits, egg yolk pie, egg roll, bread, sausage, seaweed, frozen food, medicine, medicine board, infusion bag (bottle), soap, soap, mosquito repellent incense, paper towel, toilet paper, card, adhesive tape, disposable tableware (knife and fork), etc.
The automatic packaging machine is advanced in design, reasonable in structure and reliable in performance. The automatic packaging machine adopts double synchronous belt pulling film, which is controlled by the cylinder for tension, automatic deviation correction, automatic alarm protection function, and the maximum loss reduction. The measuring device is matched, and it integrates bag making, filling, filling, printing and counting. The metering device can be modified according to the material opening and closing mode.
