General Overhaul as а Base for Stable Operation of Equipment

One of the conditions for the efficient operation at any enterprise is the availability of a well-functioning mechanism for performing repair works. The lower share of expenses for the equipment maintenance and repair in the cost of production ensures the higher manufacturing efficiency. The preventive maintenance (PM) system is the best way to prevent irrational production losses and to reduce the overhaul costs.

The PM system is a set of various works, aimed to technical maintenance and equipment repair, performed according to prearranged plan. In terms of maintenance content, complexity and frequency, scheduled repairs are divided into current, average and general overhaul, where the last one is the most expensive and time-consuming process.

Due to the availability of organizational practice and financial arrangement all planned works were performed efficiently under normal operating conditions. Main overhaul results by sectors are presented below.

Molding department. All inserts and other FBO spare parts have been replaced. It will ensure precision of the machine during blend molding and, accordingly, reduce the quantity of defective products. In addition, the such kind of works were performed, which with minimal financial investment are very costly in terms of time and human resources. Thus, Chief Power Engineer and Instrumentation Automation Engineer conducted a revision of all electrical sensors, performed modernization of molding machine in order to increase its reliability by installing a special supplementary unit. The achievement of casting conveyor highest efficiency became possible as well due to overhaul performance at DPL.
