If in the course of use, the machine suddenly malfunctions and does not work properly, everyone does not have to hurry to inspect the various components. Instead, the fault area is searched according to the circuit and working principle, and then eliminated one by one, and not to be confused. Slowly analyze. Everyone can slowly and step by step with the ideas I wrote, I believe that small problems can be found quickly.
According to the circuit and working principle to find the fault area to clear the circuit and equipment being repaired, the structure and working principle of the equipment, is gradual and avoid blind maintenance. When looking for a fault, start with the main circuit to see if the commutator is properly connected. Then check the contact system of the main circuit, replace the components, fuses, and the line itself for faults. Then check the control circuit's line connections, self-locking or interlocking contacts, and solenoids according to the control relationship between the main circuit and the control circuit. Normally, the input and output voltages of the PLC are normal, so as to find the fault location.
Through intuition can not find the fault point, from the control circuit action program to check the fault range, power failure inspection has not found a fault, you can power on the electrical equipment to check the power supply voltage is normal, cut off the circuit before the power check, the controller And the switch is set to zero, and then use a multimeter to check the power supply voltage is normal, there is no lack of phase or serious imbalance. The order of conducting the power check is to check the circuit first. Check the control circuit: check the AC system first and then check the DC system: check the sequence of operation of the control circuit, observe the operation of each component, or disconnect the disconnector and remove all the fuses. And then insert the fuses to be inspected one by one in sequence, close the switch, and observe whether the electrical components require action.
The prerequisite for these steps is to understand the structural principle of BQC anti-explosion integrated electromagnetic starter. When a fault occurs, the operating conditions before and after the fault and the anomalous phenomena occurring after the fault can be understood by looking, asking, touching, smelling, listening, and cutting. , According to the fault phenomenon to determine the location of the fault occurred, with the help of instrumentation, and continuously accumulate experience, we can accurately determine the failure of underground explosion-proof switch, and give rapid discharge failure, quickly put into production.
CPF-D series ClO2 generator is flow
rate control on-site generating system. It can add clo2 aqueous directly to
water pipe with simple, safe, reliable, stable operation. It can adjust the
dosage of clo2 aqueous through receiving 4-20mA signal provided by the flow
rate sensor. The way of clo2 producing: 5NaClO2+4HCl = 4ClO2+5NaCl+2H2O. Technology: Use sodium chlorite and hydrochloric
acid as raw materials, transmission of raw materials through two metering pumps
to the reactor, produce the concentration of more than 95% of high-purity
chlorine dioxide solution added to water for disinfection. It can automatically
adjust the dosage of clo2 solution through flow control and residual chlorine
display system. When lack of raw materials, the liquid level alarm system will
give audible and visible alarm signals and automatically cut off the power
supply of equipment. The entire control system use PLC as the core, on-site
parameters setting through the touch screen and remote control through the computer,
to realize high-performance automated management of Disinfection System. Raw
materials conversion rate is more than 95%.
