The impact and role of manual gas valves

The minimum frequency Gas Grill Valve is the minimum operating frequency that people needed when using the drive on its setting. Its main role is to: meet the technical requirements; protection of the motor; ensure that operators can accurately determine whether the electric pump.
Once the inverter set the minimum frequency value at runtime will not accept less than the minimum frequency value below any frequency requirements (except for the minimum frequency value reset), and closed-loop control circuit, the signal is interrupted when the instrument when the drive is running at the minimum frequency. From mains detection, the detected signal is sent to the new regulator, the regulator output signal is then applied to the inverter. FCCU 301 into the furnace back on this proposal refinery pump into use.
Wind off Manual Gas Valves and wind effects normally open Manual Gas Valves, instrument signals big, the operating frequency of the inverter is high, small instrument signal, the frequency inverter is running low, the instrument signal interruption, the operating frequency of the inverter frequency, compared with the minimum value. Therefore, the new closed-loop control system is put into use after the inverter formed off Manual Gas Valves must be noted that the effects of wind and wind original control system open Manual Gas Valves caused by the different signals, and to solve them.
The impact of wind wind off gas patio heater valve off Manual Gas Valves is the role of the larger instrument signal, the smaller the Manual Gas Valves opening, the signal is interrupted, the Manual Gas Valves is fully open. Taking into account the role of the inverter, the signal must be sent to the meter drive all the way to reverse processing, and must be set according to the technical requirements of the minimum frequency value. In this way, large signal, the pump speed is small, small signal, the pump speed is large, there is no signal, the pump will run at the minimum frequency value corresponds to the rotational speed to meet process requirements.
