Analysis of the circuit diagram of the two compressors' phase failure protection

Analysis of the circuit diagram of the two compressors' phase failure <br><br> Air compressor phase failure <br><br> circuit In the figure, KP is the electrical contact pressure gauge Ai is the CD4073 AND gate circuit, Az is the ~D4025 NOR gate circuit, and A3 is the CD4071 OR gate circuit. The 7806 three-terminal fixed integrated voltage regulator is used as the control circuit for the DC working power supply. When the AC power fails, the relay KA is released and the motor stops.

Judgment and repair method of refrigeration compressor jam

First use the AC current gear of the multimeter, clamp the N-terminal lead of the outdoor unit with the clamp head, measure the outdoor unit current, when the compressor is powered on, the measured current is about 65A, which is much larger than the starting current, indicating that the compressor may be stuck Can not start.<br></br>

Enterprise Guide-Purchase Air Compressor Pre-test

1. The feasibility of power saving transformation of air compressor The energy consumption of air compressors during use is obvious to all. The Zhongtian high-pressure fan power saver developed by okmarts.com based on the principle of frequency conversion can save electricity for all motor-driven air compressors. The overall power saving effect is remarkable, with a power saving rate of 20-50%.

Air compressor installation rules

1.Installation The selection of the installation site is most ignored by the staff. Often after the compressor is purchased, it is randomly located and used immediately after piping. There is no prior planning at all. Little did they know that such a sloppy result would cause future compressor failure and maintenance difficulties and poor compressed air quality.

How to realize the variable flow regulation of the circulating water pump in the heating system

After heating metering and charging, the radiators are equipped with temperature control valves. Due to the regulating effect of the temperature control valve, the heating system changes from constant flow (that is, quality adjustment) operation to variabŒﰨ2䀀湠疌
