  Fault Detection and Self - stop Device of Water Jet Loom

  Water jet looms with multiple fault detection and self-stop device to ensure the normal work of the loom. Its main role is as follows:

  (1) left and right side of the twist from the stop: installed on both sides of the loom twisted side of the axis. When the twist yarn is broken, Water Jet Loom the yarn guide hook relies on the spring force to cause the process contact action to issue the parking command. Usually using brush-type technology contacts or non-contact switches, such as reed switches, photoelectric switches, proximity switches and so on.

  (2) warp ultra-tension from the stop: Water Jet Loom installed in the loom on the left side of the rear, controlled by the loose arm. When the warp tension is too large, issue a stop command. Usually used micro limit switch.

  (3) waste silk cheese decisive stop: installed in the right side of the loom, controlled by the guide hook. When the waste silk twisted cheese yarn is broken, the guide hook action issued a parking command. Usually use the guide hook hook technology contacts.

  (4) waste silk from the stop: installed in the loom on the right front, by the lever control, when the waste wire is broken, the lever action, Water Jet Loom connected to the relevant contact, issued a parking command. Usually using a Hall switch or a process contact.

  (5) fixed length from the stop: installed in the loom length table inside, when the fabric reaches a predetermined length, Water Jet Loom issued a parking or drop instructions. If you use the mechanical length of the table, then use the micro switch to send the message; use the electronic meter long table, the direct message.

  (6) Other self-stop: In addition to the above fault detection, most of the water jet loom also has the following fault detection (not part of the process from the stop).

  ① the main motor and air pump motor internal temperature switch (motor overheating protection), when the motor overheating, automatic parking.

  ② brake internal temperature switch (electromagnetic brake overheating protection).
