INSPECTION , TESTING & MEASUREMENT
Maintenance in the paint shop
The cost in replacing damaged plant , subsequent loss of production and of customers can be substantial .
This is why it is important to have your paint plant serviced & maintained . Premiere Servicing can undertake all your paint plant maintenance including the regular servicing of gas burners , oven data logging , measuring of extraction rates , replacing filters , checks on fan blades / fan belts and LEV testing .
There are however , two other preventative maintenance checks which are really import and are rarely carried out . These being vibration testing and thermal imaging .
Vibration testing of fan and pump motors can determine potential bearing failure , out of balance impellers , motors out of alignment and even loose mountings . Regular testing of motors can highlight a slow but gradual potential for motor and impeller failure . Oven fan impellers are not always held in stock by the manufactures , failure will often result in an oven being out of production for several days .
Thermal imaging can identify this problem and pinpoint areas of concern .
Safety interlocks
When a gas engineer carries out a service on any gas burner he should also check and test all associated safety interlocks that should be fitted to the plant under current IGEM regulations .
Other electrical interlocks found in most paint plant comprise of wiring the burner controls through fan contactors , overloads , and inverters through either current monitoring or associated run signals .
It is quite common to find pressure switches that have failed in the closed position or even linked out by a “ local ” electrician who has no experience in gas burner safety . High limit thermocouples are often , located in the wrong position and therefore not provide any degree of protection against a fire hazard
Heat loss through oven body panels , explosion relief and external ducting on high temperature process plant can be quite significant , especially on the older plants due to insulation degrading with age . This leads to operating inefficiencies , potential damage to motor cables , burner controls and pressure switches . Excess heat creates hot workshops especially in warm summer conditions which become very uncomfortable to work in
It is critically important to make sure that the engineers servicing and maintaining your plant are both experienced and knowledgeable in current process plant regulations .
Premiere servicing has engineers who undertake constant training in all aspects of burner servicing , plant safety , installation and commissioning and the requirements of gas burner safety within the paint shop environment .
