Application of VEICHI AC80C in oilfield pumping unit

The beam pumping unit, commonly known as "kowtow machine", is the main equipment in oil pumping industry, of which the number reaches more than 100 thousand units. The total installed capacity of motor is 35 million kW, and the annual power consumption is over ten billion degrees. The power consumption of pumping unit is about 40% of the total power consumption in oilfields, and thus the efficiency is very low.

Applications of VEICHI AC200L series frequency inverters on wire drawing machine

The wire drawing machine is important equipment for metal wire production and mainly for drawing the metal wire into various specifications of the filament. It means that the electrical control of wire drawing machine demands high standards. The frequency Inverter is the main part of the electrical control system, particularly the precision of tension control directly affects the quality and output of the product. VEICHI AC200L series wire drawing machine special frequency inverter by its outsta

Brand-new ap100 series dedicated and integrated air compressors have been surprisingly launched

For the current requirement that high-speed synchronous motor output usually exceeds 300Hz, AP100-K has a vector control algorithm up to 600Hz by using industry-leading vague PI control algorithm that could make sure fast regulation, no overshoot and fast response.

Solution of motor self-tuning fault

Fault Name:Motor self-tuning fault.Fault Symptom: AC200T frequency inverter reports E.TEL during the static self-tuning.

Solution of the over-voltage fault happens during constant speed

Fault Name:Over-voltage fault happens during constant speed.Fault Symptom:AC200T-T3-22G frequency inverter is used for unwinding and E.oU3 would be reported when running for a period of time.

Solution of the motor driven by AC100-K shakes during operation

Fault Name:The motor driven by AC100-K shakes during operation.Fault Symptom:The motor driven by AC100-K shakes when the gas consumption on the site is small.

Solution of err2 fault (output phase failure) is reported during frequency inverter’s operation

Fault Name:Err2 fault (output phase failure) is reported during frequency inverter’s operation.Fault explanation:Err2 is the fault reported by the frequency inverter when the output current is not balanced.

Solution of OC1 fault occurs during the frequency inverter’s operation

Fault Name:OC1 fault occurs during the frequency inverter’s operation.Fault explanation: The OC fault is a sudden change in current detection during frequency inverter operation. In order to prevent it from being damaged by an excessive current, the frequency inverter internally collects the current signal and protects itself. Specifically, OC1 (over-current fault during acceleration), OC2 (over-current fault during deceleration) and OC3 (over-current fault at constant speed) are assorted accord
