Notice for installation of contactor of automatic packaging machine

1, automatic packaging machine contactor installation notice before installation

(1) automatic packaging machine contactor installation notice; The technical data of the contactor nameplate and coil of the vacuum packing machine (such as rated voltage, current, operating frequency and power duration, etc.) should be checked to see whether they meet the actual requirements for use.

(2) automatic packaging machine contactor installation matters needing attention; Check the appearance of the contactor of the packaging machine, there should be no mechanical damage, apply the hand to push the moving part of the contactor, the product should be flexible, no stuck phenomenon, and should check whether there is no debris into the contactor.

(3) automatic packaging machine contactor installation matters needing attention; On the newly bought or has been put on use for a long time packaging machinery contactor, do a good disassembly inspection, the internal parts of the product should be no defects, and with gasoline wipe off the surface of the iron core anti-rust grease or clean the iron dirt bonded to the surface.

(4) automatic packaging machine contactor installation matters needing attention; Measure the coil resistance, check and adjust the contact head's opening distance, overpass, initial pressure and final pressure, and make the contact move synchronously.

(5) check the insulation resistance of the product.

2, automatic packaging machine contactor installation notes

(1) automatic packaging machine contactor installation notice; Leave proper arc space as required to avoid arc burning adjacent devices.

(2) automatic packaging machine contactor installation matters needing attention; The installation position should be correct. Except for special orders, it should be installed on the vertical surface. Even the direct action contactor should not be installed at will.

(3) automatic packaging machine contactor installation matters needing attention; Installation and wiring, should pay attention to do not make parts lost into the electrical internal. The screws should be fitted with spring washers and plain washers, and the screws should be tightened to prevent loosening.

(4) automatic packaging machine contactor installation matters needing attention; When the contactor is fixed, hole tapping should be done on the power distribution, and nut fixing method should not be adopted.

3, automatic packaging machine contactor installation matters needing attention; Check after installation

(1) automatic packaging machine contactor installation notice; The arc cover of the contactor of the fully automatic packaging machine must be intact and firmly fixed. It is never allowed to operate without or with a damaged arc cover.

(2) automatic packaging machine contactor installation matters needing attention; After checking the wiring is correct, the operating value of the product should be measured several times when the main contact is not live, and it must meet the specified requirements of the product.

(3) automatic packaging machine contactor installation matters needing attention; For the newly replaced vacuum contactor, its vacuum degree should be measured, and its vacuum degree must meet the requirements.

(4) automatic packaging machine contactor installation matters needing attention; After putting into operation, the contactor parts should be checked regularly for dirt, especially the core surface. If there is too much grime on the core surface, it will affect the normal operation of the contactor. If the accumulation of grime in other parts, will also affect the contactor pressure level. Had dirt, usable compressed air or blow off with leather tiger, also usable wool brush goes, but avoid by all means is wiped with wet cloth, lest produce electric shock accident. In addition, the core face avoid oil, it is likely to make armature and core absorption is not firm, so once found oil, should immediately clean with gasoline, and then wipe a thin vaseline, in case the surface rust.

(5) automatic packaging machine contactor installation matters needing attention; In use, the contactor parts should be checked regularly, the movable part should not be stuck, the fastener should not be loose. If there is any damage, it should be repaired in time.

6 automatic packaging machine contactor installation notice; Contact surface should be kept clean, do not allow oil. When metal beads are formed on the contact surface due to arc action, they should be removed in time. However, the contact resistance of oxide film produced on the contact surface of silver and silver-based alloy is very small, so there is no need for trimming, otherwise the contact life will be shortened. When the contact is seriously worn, the overpass should be adjusted in time. When the thickness is only 1/3, contact should be replaced to ensure the reliability of the work.

(7) notes for installation of contactor of automatic packaging machine; For the coil and contact temperature rise, should be regularly checked, if found too high temperature rise, it is necessary to timely identify the cause, appropriate treatment (including replacement for a new or adjusted contact spring). No matter where you check the temperature rise, you should never judge it by the touch of your hand, because this is not accurate.
