Causes and treatment of inaccurate delay of time relay in food machinery plant

1. Cause and treatment of inaccurate delay of time relay in food machinery factory; Air damped time relay for vacuum packing machine

(1) food machinery plant time relay delay inaccurate reasons and treatment; When the air chamber is disassembled and reassembled, it is not operated according to the regulations, resulting in loose air chamber seal, resulting in air leakage and inaccurate delay, or even no delay in serious cases. Do not disassemble the air chamber during maintenance of air damped time relay of packaging machinery and equipment. Operate according to the specified technical requirements during assembly to ensure airtight air chamber.

(2) food machinery plant time relay delay inaccurate reasons and treatment; The air chamber is not clean, dust or particles into the air passage, so that the airway obstruction, delay time. The relay of the packing machine should be removed, the air chamber should be disassembled in a clean air environment to remove dust and particles, and then reassembled.

(3) food machinery plant time relay delay inaccurate reasons and treatment; When installing or replacing the packaging mechanical time relay, the installation direction is wrong, resulting in the change of working state of the air chamber, making the delay inaccurate. Therefore, the relay cannot be inverted or installed horizontally.

(4) vacuum packaging machine air damping type time relay; The use time is long, the air humidity changes, make the air chamber rubber film deterioration, aging, hardness change, resulting in delay is not accurate, should be timely replaced rubber film.

2. Cause and treatment of inaccurate delay of time relay in food machinery factory; Automatic vacuum packing machine transistor type time relay

(1) food machinery plant time relay delay inaccurate reasons and treatment; Adjust the delay time of the adjustable potentiometer used for a long time, so that the potentiometer inner wear or dust into the vacuum packaging machine delay time is not accurate, can use a small amount of gasoline along the potentiometer handle drip, and rotate the handle, or to wear serious potentiometer timely replacement.

(2) food machinery plant time relay delay inaccurate reasons and treatment; Transistor damage, aging, resulting in delay circuit parameters change, delay time is not accurate, or even no delay. The relay of vacuum packing machine should be removed for maintenance or replacement.

(3) food machinery plant time relay delay inaccurate reasons and treatment; Transistor time relay due to vibration, components solder loose, socket off. Careful inspection or rewelding should be carried out.

(4) food machinery plant time relay delay inaccurate reasons and treatment; Check whether the appearance of components is abnormal. Do not replace or weld the shell at will to avoid damaging components and expanding the fault surface. When replacing or replacing, use transistor time relays of the same model, the same voltage and similar delay range.

(5) cause and treatment of inaccurate delay of time relay in food machinery factory; General transistor time relay is the use of capacitance charge and discharge characteristics to delay. Capacitance change value, change the charge and discharge time, so that the delay is not allowed, should replace the appropriate capacitance.

3. Cause and treatment of inaccurate delay of time relay in food machinery factory; Vacuum packing machine electromagnetic time relay

Cause and treatment of inaccurate delay of time relay in food machinery factory; For full automatic packaging machine, electromagnetic time relay delay is not accurate, most of the non-magnetic gasket wear serious, should be promptly replaced with a new non-magnetic gasket.

4. Cause and treatment of inaccurate delay of time relay in food machinery factory; Clock type time relay

Cause and treatment of inaccurate delay of time relay in food machinery factory; Clock type time relay delay is not accurate, most of the fault for the clock mechanism, should be timely repair clock mechanism.
