Automation Division was given the task to automate one of the most complex pieces of equipment in the production line – a block form as algorithm of actions of the operator of block forms reveals a number of serious problems to be solved: operator during the cycle must exhibit ball valves for steam power in the form as instructed. Operator should be every 15 minutes to conduct the whole cycle over again. Actions to manage the block form of uniform, but they require some attention. Against the background of general fatigue that leads to random errors in the management of a block form. Purging, steaming and cooling makes a statement, focusing on the testimony of gauges and clocks. So, first of all, it was necessary to relieve the operator from repetitive work.
If the entire cycle of sintering the foam will meet the automation, the operator can perform other operations on the shop floor, for example, prepare materials or cutting blocks. This implementation would reduce the number of jobs in the shop, which significantly would reduce production costs. Requirements for the functional composition of the device: Having a single control panel throughout the block-form. A controlled valves and gates. A logic automatically controls the valves for steam supply valve position for loading of raw materials, fan control load and the vacuum pump. The presence of the operator panel to alert the operator informed of progress. A logic that implements the automatic start and end of the process.
Its cooling system should be refilled with liquid ethylene glycol on the basis of a low-silicate and recommended by the manufacturer containing additives inhibitors. Cooling system should be completely clean vehicle with a high cleaning ability, and fill with fresh fluid with additives inhibitors at least 1 time in 2 years through 1200 motor-hours. It is important that in this case were also replaced the thermostat. Very useful for chemical analysis of coolant every 500 – 600 Moto-hours. It is equally important to provide a service replacement program, cracked, swollen or worn hoses. Outdoor pollution radiator can bring a lot of problems. It should be clean all the dirt – as nabivshuyusya between the plates of the core, and has accumulated around it. Check to see whether Jammed fins, if necessary, straighten them.
Make sure that all the panels, air ducts are in place. Check for frayed fan belt is not whether he slips on the pulley. When listing seems that the workload is very big, but in reality they do not require much time. Their execution brings many benefits, so the technique works and does not idle in the repair. According to the magazine 'Fixed Assets' 9 / 2002 'The secret of longevity: the withdrawal of the heavy lifting and transport equipment' by O. Zharkov Motor When the oil in a region where know the exact content of sulfur in fuel, or if you definitely know that the sulfur content above 0.5%, you should choose engine oil with higher TVN (base number), that used oil higher operating group of API or the national standard.
