We know that the air compressor is an indispensable core component of the powder material transporter . Maintaining the air compressor is an important guarantee for the normal operation of the powder material transporter. Next, Xiaobian led everyone to understand the commonly used air compressors in China and its working principles. The commonly used air compressors for powder and grain material carriers are vane type and swing type. The principle of the vane air compressor is driven by the power output device to deliver pure compressed air with a certain pressure to the powder tank. The cylinder of the air compressor is cylindrical. The cylinder is equipped with a rotor eccentric to the cylinder, and the rotor is opened. A number of radial slots are provided with blades. When the rotor drives the blades to rotate at high speed, the blades are thrown along the radial slots and press against the inner wall of the cylinder under the effect of centrifugal force. Due to the existence of the eccentric distance between the rotor and the cylinder, the volume formed by the vane on the entire circumference and the inner wall of the cylinder is changed, so that the filtered air is sucked into the air inlet and discharged from the air outlet. As the rotor continues to rotate, the compressed air is continuously discharged. The compressed air discharged by the air compressor must be filtered by a water separator before being fed into the tank. The working principle of the swing type air compressor: When the power output device drives the air compressor crankshaft to rotate, the rotor shaft of the air compressor swings back and forth through the connecting rod. Because the rotor is fixedly connected to the rotor shaft, the rotor also performs swinging motion to compress air. When the rotor swings in a counterclockwise manner, the rear of its sector plate is in a low pressure state, and outside air is drawn into the cylinder through a valve on the side of the intake valve. At this time, the valve on the other side of the intake valve is closed; at the same time, the air sucked in the last working cycle in the cylinder is compressed and discharged from the exhaust valve. When the rotor oscillates from one dead center to the other, a working cycle is completed; when the rotor oscillates in the clockwise direction, the intake and exhaust valves perform intake and exhaust operations in opposite directions, and the air compressor is completed again. A working cycle. Since both sides of the rotor sector plate are working volumes, when the rotor is oscillating, both sides of the rotor can be suction-pressed, the crankshaft continues to rotate, and the compressed air is continuously discharged in the cylinder. Every revolution of the crankshaft, the rotor swings twice to complete two working cycles.
DIN2634 flange have two holes, can wear bolt, make the two flange tight even.Between the gasket seal.It is the connection of the two pipes, fittings or equipment, fixed on a flange, a first between the two German standard flange, and flange pad, bolt fastening together, complete the connection.According to the connection parts of flange and flange can be divided into the container.This product is mainly used in oil and gas pipeline engineering, the natural gas pipeline engineering, chemical plants, municipal engineering, sewage treatment, power plant, shipbuilding, pharmaceutical, dairy products, beer, beverage, water conservancy and other industries.DIN2634 flange will not produce corrosion, pitting, corrosion or wear and tear, play an important role and value in use, used in different industries and fields.
Butt welding flange is two large diameter pipe connection device, usually two flange and number of the bolt, its plastic strength is low, after adding suitable amount of carbon becomes hard, plastic lower strength enhanced.Connection it may need to bear very high tensile, compression, torsion and shear strength.Butt welding flange conveniently, manufacture simple, low cost, widely used, but with poor rigidity, therefore shall not be used for supply and demand, flammable, explosive and high vacuum degree requirements of the chemical process piping systems and height, extremely dangerous situations.Sealing surface type plane and surface.Butt welding flange welding electrode consumption is much, can not stand high temperature, high pressure, repeated bending and temperature fluctuations.
