Installation and maintenance of rice brick food packaging machinery control relay

Installation and maintenance of rice brick food packaging machinery control relay; For vacuum packaging machine control relay, the important thing is reliable operation and accurate action, which not only depends on the performance of the product itself, but also whether the product is correctly selected and reasonable maintenance has a great relationship, in the packaging machine control relay installation, adjustment and operation should pay attention to the following problems.

1. Installation and maintenance of rice brick food packaging machinery control relay; Inspection before installation of relay for packaging machinery

(1) rice brick food packaging machinery control relay installation and maintenance; According to the technical requirements of the control circuit and equipment, carefully check the nameplate data of the relay of the vacuum packaging machine, such as the rated voltage, rated current, setting value and delay parameters of the coil to meet the requirements.

(2) rice brick food packaging machinery control relay installation and maintenance; Check whether the moving part of the relay of the vacuum packing machine is flexible and reliable, and whether the cover and shell are damaged or missing

(3) rice brick food packaging machinery control relay installation and maintenance; Remove dirt from parts surface. For example, remove anti-rust oil from the core surface of intermediate relay to ensure the reliability of operation.

2. Installation and maintenance of rice brick food packaging machinery control relay; Inspection of installation and wiring

(1) rice brick food packaging machinery control relay installation and maintenance; When installing wiring, check whether the wiring is correct, whether the wire is suitable, and whether all the mounting screws and wiring screws are tightened.

(2) rice brick food packaging machinery control relay installation and maintenance; To control the electromagnetic relay, should be in contact not charged situation, will attract the coil charged for several times, whether relay operation is reliable, the more strict control project, also must carry on the power calibration, conditional or when necessary, but also for loop tracking check, look to whether can meet the application requirements, otherwise the check and adjust to each element.

(3) rice brick food packaging machinery control relay installation and maintenance; For the protection of the vacuum packaging machine relay, such as over-current relay, under-voltage relay, etc., should check again whether the setting value is in line with the requirements, to be confirmed or adjusted accurately before the operation, to ensure the reliable protection of the circuit and equipment.

(4) rice brick food packaging machinery control relay installation and maintenance; Installation, should not be used with the installation of nuts, in order to facilitate the replacement.

3. Installation and maintenance of rice brick food packaging machinery control relay; Operation and maintenance

(1) rice brick food packaging machinery control relay installation and maintenance; Keep the relay of the automatic vacuum packing machine clean, avoid the accumulation of dirt, reduce the insulation level and cause the flashover.

(2) rice brick food packaging machinery control relay installation and maintenance; Monitor the working condition of packing machinery relay frequently. If abnormal phenomenon is found, the cause should be found out.

(3) rice brick food packaging machinery control relay installation and maintenance; It is necessary to pay attention to the change of environmental conditions. If the rapid change of temperature, the change of air humidity, the change of impact and vibration conditions and the invasion of harmful gas or dust do not meet the requirements of the operating conditions of the relay, reliable protective measures should be taken to ensure the reliability of the relay.

(4) electromagnetic relay setting value adjustment should be carried out in the coil operating temperature, to prevent the cold

State and thermal state affect the action value.

(5) regularly check whether the wiring parts of the relay are loose, damaged or corroded, and whether the moving part is stuck. If so, repair or replace it in time.

6 should keep contact clean and reliable contact. When the contact is worn to 1/3 thickness, replacement should be considered. If the contact is found to wear too fast, consider the use of flower circuit; If have more serious burn loss, burr wait for a phenomenon, usable small file file repair, with carbon tetrachloride or alcohol wipe surface, avoid by all means burnish with sandpaper. After the shock repair, please pay attention to adjusting the shock opening distance, overpass, contact pressure and reaction force.
