M type overhead mixing unit
■ China's first, best balanced performance, energy efficient large displacement mother station compressor unit.
■The domestic exclusive implementation of a five-stage compressor type, the minimum inhalation of 0.03MPa, high-efficiency and energy-saving large displacement standard station compressor unit.
■ Four rows of horizontally symmetric balanced compressors, the four rows of cranks are 90° each other, the inertia moment is completely balanced, the unit runs extremely smoothly, and the vibration is extremely small.
■ There is only one cylinder in the compressor. The maintenance of the piston ring, packing and wearing parts does not require disassembly of the cylinder, and the maintenance is extremely convenient.
■ Adopting the energy-saving non-balanced section compressor technology (patent number ZL98 2 29860.9) and the high-pressure packing sealing technology obtained by the national patent technology, the energy saving effect is remarkable compared with the average energy saving of the domestic balanced section compressor by more than 10%. Nissan's 100,000 square mother station saves more than 480,000 kWh of electricity per year (calculated at an inlet pressure of 1.0 MPa).
■ The compressor unit is integrally armored, and the motor directly drives the compressor through the flexible coupling. It is easy to transport and easy to install.
■ Compressor can be equipped with soundproof cover as needed to meet outdoor weather operation; space heater, flammable gas alarm system, maintenance lifting beam, explosion-proof lighting, safety door, adjustable blinds and special elimination channel. Safe, environmentally friendly and easy to maintain.
■ The lubrication system is equipped with a lubricating oil heating system and a pre-lubrication system to automatically control the temperature of the lubricating oil to ensure lubrication of key parts such as the crosshead slide. The piston ring and packing seal assembly adopts imported PTFE oil-free lubricating material, which has good wear resistance and does not cause malignant accidents such as “pull cylinder”.
■ The air valve is an air cushion valve that has won the National Science and Technology Progress Award. The “air cushion effect” generated by the air cushion slows down the impact of the valve plate on the valve seat. The valve plate is made of stainless steel. The valve spring is a special spring steel wire imported from Sweden, which has low noise and long service life.
■ The basal alloy is welded to the crosshead support surface for good wear resistance and low maintenance cost.
■ The cylinder liner is a pre-film cylinder liner with a low coefficient of friction. The cylinder is in close contact with the piston ring and the support ring and has a long service life.
