1. The selection of large and medium-sized air compressor equipment should be consistent with the production process of the enterprise
Air compressor equipment is inseparably related to future production and manufacturing, and it is a fundamental requirement to be consistent with its own production process. Insist on seeking truth from facts is the quality required by equipment workers. At this stage, there are various types of equipment in the sales market, and each type of equipment has its special use of indoor space and market share. Some are good at completion, some are good at saving costs, some are good at improving work efficiency, some are good at technological innovation, and some are good at low equipment failure rate. In order to save costs for high-efficiency equipment, the key to low failure rate of excellent equipment is to make full use of its advantages under the current standards of the enterprise, and the company’s own processing technology, management capabilities, service facilities, technical energy, and professional skills of maintenance staff. Consistent.
If some companies advocate import substitution in equipment upgrades, choose some large-size equipment, and seek to improve productivity, the result is that the equipment becomes larger, but the efficiency is not satisfactory. The reason is that the import substitution of the equipment is an automatic control. For example, some shortcomings in the processing technology cannot be dealt with, and only the import substitution of a certain kind of equipment is discussed independently, which usually leads to the situation of the big car and the increase in the comprehensive cost.
The situation of the "big lar car" is very extensive, and it is caused by two reasons:
First, in the model selection process, the air compressors selected by the project staff usually exceed the greater requirements of the drive load.
Second, the load used by the air compressor is originally changed, and the size of the air compressor must be selected to consider the larger load. In fact, the larger load only interrupts, and the load at other times is much smaller.
Everyone looks at the results and main manifestations:
The gas usage of most processing plants is always changing. When the usage decreases, the gas working pressure just begins to rise, but on the contrary it decreases. This situation also confirms two things:
First, the volume of the gas compressor must exceed the amount used. The bottom pressure setting of the pressure controller must consider the working pressure value required by the processing plant. Second, the bottom pressure setting of the pressure controller must consider the working pressure value required by the processing plant.
