High Frequency Welding Machine Maintenance work is nessery

Posted by davisonmachinery on January 9th, 2017

High Frequency Welding Machine Maintenance work also includes the maintenance of spare parts on the equipment, such as backup tubes and equipment should be used on a regular basis for the rotation tube to prevent long-term storage to reduce the vacuum tube.

1, Each class maintenance

(1) take over the water cooling equipment to check the flow of water pipes have abnormal phenomenon. Use evaporative cooling tube equipment, to check the water level of distilled water tank is qualified.

(2) check the tube glass tube and core column cooling air volume and other ventilation cooling facilities are normal.

(3) equipment at work, should always check the indicators of each instrument, every hour record. Equipment repair or replacement of components, should be detailed records in the duty book.

(4) before the shift to wipe the equipment outside the dust, clean the room health.

2, weekly maintenance

(1) Check the contacts of the AC contactor for ablation, wiring loosening.

(2) measuring the insulation resistance of cooling water. Water-cooled tube anode to ground resistance should be greater than 300K Europe

(3) the tube and the filament tube of the cooling water pipes are mostly rubber tube, easy to aging, to double-check. For the aging of the rubber tube is about to break, to be updated.

(4) on the chassis to do a clean dust, wipe the high-pressure porcelain insulators and pillars of dust, pay attention to the fan inlet on the dust filter cleaning. To prevent air into the blocked, the amount of wind to reduce.

3, monthly maintenance

(1) Check the contacts and connections of the intermediate and overcurrent relays. Clear the scale on the anode (also according to the water quality of cooling water, to determine the maintenance cycle)

(2) of the cold water flow for the flow to determine the flow meter can be detected. No flow meter can be cooled out of the water into the container, the time for one minute, the scale of the container is the weight of water, available flow kg / min, that is liter / min. And compared to the previous record, if a significant reduction should be to find a reason to solve in a timely manner.

(3) Check the plug-in fuse box fuse loosening, oxidation, erosion and other phenomena.

(4) Check the air switch and knife switch contacts.

(5) check the protective measures, such as over-voltage, over-current, door switch, inadequate cooling, the temperature is too high protection device is effective. If there are problems to be repaired in time.

(6) a backup tube unit, the backup tube and equipment can be used on the rotation of the rotation time can also be removed and the anode scale at the same time.

4, six months of maintenance

(1) Check the low-voltage electrical control circuit insulation is qualified.

(2) with megger detection high voltage rectifier transformers, high voltage cables, high voltage silicon reactor and other high-voltage devices, insulation resistance, the value should meet the requirements.

(3) Check the tube water tube inner tube roundness and positioning of the height of the protrusions, to prevent the partial tube anode caused partial overheating. And check the water jacket and the inlet pipe fittings whether the fouling, anti-corrosion electrode is normal and so on.

(4) Check the overcurrent relay setting current value.

(5) at work, the higher the temperature of the connecting conductor, such as filament lead, welding transformer primary coil soft connection line, if found to have bad contact oxidation should be added processing.

(6) of the motor, pump, with electrical and other facilities maintenance.

(7) on the shelter, such as the top of the cabinet, cable trench, etc. for a thorough cleaning

The above refers to the general situation, the plant equipment and the use of different conditions, maintenance of content and the cycle according to the specific circumstances of the increase or decrease.
