Preventive maintenance and repair
1 hydraulic oil hydraulic oil is its chemical stability, namely the oxidation stability. Oxidation is the main factor to decide the effective service life of hydraulic oil, oxygen generation wood tar, oil sludge and carbon residue and other insoluble matter pollution of hydraulic system, and increase the wear of the hydraulic units, reduce the gap, plug the holes, eventually led to the hydraulic system failure. Hydraulic oil oxidation rate depends on itself and working conditions and other factors, among which temperature is one of the main factors, so the use of hydraulic oil is suitable, the degree of oxidation and regular inspection of hydraulic oil (from the oil itself color turn deep and judgment), more than a certain number of work hours after active oil is absolutely necessary the.
2 filter cleaning oil filter to clean hydraulic oil, so oil filter should be cleaned once every three months to maintain the oil gas suction pipe flow, at the same time, check whether there is damage to the oil strainer. Usually the filter size shall not be greater than 200.
3 cooler cooler should be washed every two years, or on the basis of their ability to work is not reduced and cleaning, cooler internal blockage or fouling will influence the cooling efficiency, cooling water should choose soft (no minerals) is preferred
Injection molding machine, injection molding machine or injection machine. It is the main forming equipment plastic products, thermoplastic or thermosetting plastics using plastic molding into various shapes. Divided into vertical, horizontal, all electric. The function of heating plastic injection, high voltage is applied to the molten plastic, so that the injection and full of mold cavity
