At present, with the continuous development of technology, modern electroplating equipment has become an indispensable part of the development of modern electroplating enterprises.
If electroplating enterprises want to produce and process electroplating products on a large scale and in large quantities in a short time, they cannot do without modern electroplating equipment.
In order to ensure the normal operation of electroplating equipment, it is necessary to carry out timely and effective repair and maintenance of electroplating equipment.
I, Repair and maintenance of electroplating equipment
After putting into production for 1 month, the mounting screws in the rack should be retightened.
To ensure that the rack is kept clean for a long time, the sliding doors, pedestrian walkway railings and stainless steel column surfaces in the rack should be cleaned every 4 months.
The reducer shall be checked every 700~800h to check whether it produces abnormal noise, and the tightness of the reducer base shall be checked and adjusted.
In order to avoid damage to the shaft, bearing and housing, it is forbidden to use a hammer to knock when installing the pulley, coupling and gear.
The brake mechanism shall be inspected and debugged every 7000~8000h. The contact condition of the power line in the junction box should be checked every 7000~8000h. Once the connector is loose, it should be fastened in time.
For the wire insulation layer, once there is aging and melting phenomenon, the power line should be updated in time, so as to effectively improve the insulation of the power line. For bearings and bearing seats, check their lubrication and tightness every 7000~8000h.
For lifting guide wheel, check and adjust its clamping clearance every 600~700h, and consider whether to replace the guide wheel according to the actual situation every 10000h.
For the traverse guide wheel, its installation clearance shall be checked and adjusted every 700~800h. For the secondary traverse driving wheel and driven wheel, its positioning and fastening status shall be checked every 700~800h. Once there is looseness and displacement, it shall be fastened and aligned in time.
For the sling splint, its tightness shall be checked every 10000h, the bolts shall be fastened, and the sling shall be replaced every 20000h according to the actual situation.
The relative position of the inductor and the sensing piece shall be checked and corrected every 7000~8000h. For the two-tooth gear rack, the synchronization of its engagement shall be checked and adjusted every 2000h.
For the reducer, its operation status shall be checked every 600~700h, and the tightness of the reducer base shall be checked and adjusted every 1000h.
For the brake mechanism, its braking performance shall be checked and adjusted every 7000~8000h. The contact condition of the power line in the junction box should be checked every 7000~8000h. Once the connector is loose, it should be fastened in time.
For the wire insulation layer, once there is aging and melting phenomenon, the power line should be updated in time, so as to effectively improve the insulation of the power line. For the supporting roller bearing, grease it once every 5000h and replace the bearing with serious wear.
For the mounting bolts of the vibration motor, the wear of the vibration rubber should be checked once every 1000h, and the vibration rubber with serious wear should be replaced.
4.Circulating filtration system
For the pump motor power line, the contact condition of its connector should be checked every 1000h. Once there is looseness, it should be fastened in time. In order to ensure the safe insulation and good contact of the line, the aging wire should be replaced.
For the filter element of the filter, it should be replaced every 10 days to ensure the flow of the filter. In order to prevent the float in the flowmeter from crashing rapidly and causing the glass tube to break, the ball valve in front of the flowmeter should be opened and closed slowly. At the same time, the readings in the filter pressure gauge should be checked once a day.
Generally speaking, the pressure gauge will not be damaged, unless the diaphragm in the pressure gauge seat has aging, cracking, perforation and other phenomena, resulting in the direct inflow of liquid medicine in the pressure gauge, which will corrode and damage the Bourdon copper pipe in the pressure gauge.
In this case, the pressure gauge and diaphragm need to be replaced. If the pressure gauge reading of the filter is low, the following aspects should be checked: whether the power connector of the pump motor has phase loss and poor contact; Whether the pressure gauge fails; Whether the pump outlet pipe is blocked; Check whether there is air inflow between the pressure gauge and the diaphragm in the pressure gauge seat. If so, remove the pressure gauge, add water to the diaphragm chamber until it is full, and then install the pressure gauge.
If the pressure gauge reading of the filter is on the high side, the following aspects should be checked, that is, whether the filter element has serious scaling; Whether the crystal blocks the orifice of the spray nozzle in the tank; Whether the pressure gauge fails; Check whether the pump outlet pipe is blocked.
Other components, including exhaust system, heater, hanger and dagger, cooling coil, slot, anode, low pressure blower, etc. The repair and maintenance of these components should also be strengthened.
II, Maintenance before long-term shutdown
If the electroplating equipment is to be shut down for a long time, the following maintenance measures should be taken: to ensure that the machine is in a dry environment, the water on the ground should be cleaned;
To prevent aging, wrap all motors with cling paper; Inject lubricating grease into all bearings; Inject lubricating grease into all rubber wheel bearings in the crane; Wrap all fuel injection parts in the crane with plastic wrap; Clean the liquid medicine in all pipelines; Clean all heaters and cooling coils.
III, Inspection of electroplating equipment before restarting after long-term shutdown
After a long-term shutdown and before restarting the machine, remove all the wrapping paper from the equipment parts during the shutdown;
Check the contact of the terminals in all motor junction boxes. If the wires are aging, replace them;
For the reducer, check the lubrication condition in the reducer, and check whether the reducer will produce noise during the test run of the motor; Check the lubrication of all bearings and rubber wheel bearings.
Consider whether to inject lubricating grease according to the actual situation; The oil injection parts in the rack shall be inspected. Once the paint of some parts falls off and ages, they shall be repaired by spraying.
Check the fastening of all fasteners in the rack. In order to keep the machine in a clean state, the surface of all stainless steel parts, sliding doors, etc. should be cleaned; For the tank, check whether there is water leakage. If there is water leakage, repair it; All pipelines shall be inspected. In case of water leakage, the leaking pipe fittings shall be repaired and replaced.
For the brake motor, the brake performance shall be comprehensively checked, and the reliability and sensitivity of the instruments and meters in the pipeline shall be checked.
