  • DC Electric Heater Control Cabinet DJZ-03

    DC Electric Heater Control Cabinet DJZ-03

    DJZ-03 Control Cabinet of DC Electric Heater is designed and manufactured for heating control for big bolts of steam turbines. For big bolts over 56mm in diameter, the securing moment required is too big to achieve under ambient condition. As such, in order to secure the big bolts, the bolts are secured to a certain moment under ambient condition at first, then they are to be lengthened through heating, and the corresponding nuts are to be turned in a certain arc length, the bolts finally are to be secured to certain tightness.
  • MM2XP 2-pole 24VDC Digital Power Intermediate Relay

    MM2XP 2-pole 24VDC Digital Power Intermediate Relay

    MM2XP Intermediate relays are usually used to transmit signals and control multiple circuits at the same time. They can also be used to directly control small capacity motors or other electrical actuators. The structure and working principle of intermediate relay are basically the same as that of AC contactor. The main difference between intermediate relay and AC contactor is that there are more contacts and small contact capacity. When selecting the intermediate relay, the voltage level and the number of contacts are mainly considered.
    In fact, the intermediate relay is also a voltage relay. The difference from the ordinary voltage relay is that the intermediate relay has many contacts, and the current allowed to flow through the contacts is large, which can disconnect and connect the circuit with large current.
  • GJCF-15 APH Gap Control system Signal Transmitter

    GJCF-15 APH Gap Control system Signal Transmitter

    GJCF-15 APH Gap Control system Signal Transmitter and the Gap Sensor Probe GJCT-15-E are used together to process the signal measured by the probe, and after a comprehensive judgment, an execution command is issued to start the power circuit, so that the sealed sector plate rises, falls or Emergency lift to the upper limit position. It is suitable for detecting the displacement of the air preheater rotor in motion under high temperature and harsh environment.

    GJCF-15 APH Gap Control system Signal Transmitter is used in the seal clearance control system of air preheater. The key problem of the system is the measurement of preheater deformation. The difficulty is that the deformed preheater rotor is moving, and the temperature in the air preheater is close to 400 ℃, and there are a lot of coal ash and corrosive gas in it. In such a harsh environment, it is very difficult to detect the displacement of moving objects.
