How contactors achieve control

Since the main purpose of the contactor is to control the motor, the working principle of the contactor controlling the motor is introduced below. When the button is pressed down, the electromagnetic coil in the contactor gets a signal from the button, that is, through the closing action of the normally open contact in the button, the electromagnetic coil passes through the button and the fuse is connected to the power port when the coil is energized. A magnetic field is generated to magnetize the static iron core, which attracts the moving iron core so that it moves towards the static iron core and eventually pulls it together. The moving contact in the contactor contact system is mechanically fixed with the moving iron core. When the moving iron core is attracted downward by the static iron core, the moving contact also moves downwards and closes with the myeloid contact. . such. The motor is switched on via the contactor contact system and the fuse. Start up and start up Once the power supply Lt disappears or decreases significantly, so that the electromagnetic coil is not excited or insufficiently energized, the moving iron core will be released from the static iron core by the reverse force of the release spring because the electromagnetic suction force disappears or is too small. At the same time, the moving contacts that are fixedly installed with the moving iron core are also separated from the static contacts, so that the motor is disconnected from the power supply and the operation is stopped. This is the so-called undervoltage protection.

Concrete Pile Pre-stressed/Tension Machine



Concrete Pile Pre-stressed/Tension Machine:

Tension Machine is a kind of feedthrough pre-tensioing. It is also called spun pile tension jack machine, pole tension machine, prestressed tension machine etc. It is the neccesary equipment to produce Pre-stressed concrete spun pile and prestressed concrete pole products. As the end of the tension rod is connected to the anchor with thread, it can be applied to various forged anchors, chilled iron anchor used for stayed-cable bridge and other similar anchors, as well as pre-tension pulling for pipes. In accordance with actual requirement.


Spun Pile Tension machine

HH Tension Machine's advantages:

1. The large-screen LCD display.

2. Double control mechanism of touch screen and keyboard, high reliability.

3. Directly work after the input of tensioning data, and the oil cylinder will automatically complete the tensioning process to reduce uncertain factor of manual operations and improve the tensile quality.

4. Built-in SD card function, which can save the tensile data to the computer regularly, and check the record at any time.

5. With its own printer, it can print tensile data in working time, avoiding the tedious and unstable manual record and ensuring the traceability of tensegrity data is verified.
