Phosphating pretreatment washing machine instructions

Preparation before starting up

First, adjust the liquid level of each pool before starting each shift, so that it is between the upper and lower water level lines (30-80mm from the side of the water tank), and at the same time adjust the chemical concentration of the solution, and close the heating (steam) switch. To start the preheating of the pool liquid (mainly: 1, 2, degreasing tank, phosphating tank, etc.) that needs to be heated. And optimistic about the temperature control instrument temperature, the general temperature 1/2 / pool is set at 50-80 ° C, 7 phosphating pool is set at 30 ° C. The temperature of the drying zone is closed between 100 and 180 °C. Note: After the temperature is reached, the product can be put into production.

Second, turn on the high-pressure fan of the air curtain one by one and adjust the height of the air curtain so that the height of the air curtain is 30mm-50mm higher than the height of the cleaned workpiece, and feel the wind force of the air curtain is normal, otherwise check the fan and so on. component. The optimal distance from the air curtain outlet to the workpiece is 30mm, so it is required that the workpiece to be cleaned cannot be mixed with high and low. The same workpiece should be cleaned in batches, and the optimum height of the air curtain of each batch should be adjusted in time to prevent the string. The best condition for liquid and cleaning and drying. (If the scratch card is not covered by the warranty, the operator is responsible for compensation) (Note: The air curtain adjustment work is completed before production!)

3. Go to work (off work) to turn on the water pump one by one, and open the relevant spray cleaning observation door to confirm whether the nozzle is blocked or not, and clean or replace the spare parts in time. (It is best to work after work, but must check every shift)

Boot method

1. After the water temperature and the drying tunnel have reached the set temperature, the water level, and the height of the air curtain, adjust the speed of the mesh belt first, and then turn on the pump power supply, fan power supply, cooling area power supply, etc. Into the workpiece production, put the workpiece should be as full as possible according to a certain rule, the concave surface facing down (can not be stacked), and try to leave 50mm sides on both sides of the mesh belt, which is conducive to cleaning. Timely discovery of the quality of the cleaning of the workpiece. The cleaning speed of the washing machine should be as reasonable as possible (not too fast, otherwise it will not be cleaned), and the concentration of the liquid medicine should be adjusted at least twice a day. Adjust the tap water supply in the last washing area to keep the washing area clean.

Equipment maintenance

1. Every 10 days, refueling the rotating sprocket, chain, tensioning guide rail, bridge gear box, bridge sprocket box, etc., every 30 workpieces, the bridge system, the wind curtain chain (gear), the air curtain screw Wait for the oil. Always look at the voltmeter, ammeter, thermometer and other data on the electric control cabinet is normal. It is best to do the recording work by the time zone to ensure that the equipment is running normally at high quality. Generally, 100 working days are required to clean the boom and nozzle.

Second, every day after work, you must leave a full-time person to pump the phosphating solution of the phosphating working pool to the phosphating sedimentation tank, and clean and clean the phosphating working pool and phosphating pipeline equipment (open the pump cleaning), and install it as it is. In the next procedure, the bath is adjusted at a reasonable water level. Every day, the full-time staff will confirm whether the nozzle is blocked or not, and clean or replace the spare parts in time. Clean and clean the filter basket in each zone and install it back in place.

Third, the cleaning machine has problems in time to contact the manufacturer's after-sales service in time for timely solution, so that the equipment is in good condition.
