Pressure compressor tank How Much is a compressed air tank inspection required storage devices, there is a certain degree of risk, improper use can pose a security risk if and life hazards. In order to ensure the safe use of the gas tank, and the state more than 25 liters of compressed air container was pressure vessel equipment must be reported before installing air compressor price, after installing the security department of labor needed to be put into use before inspection, and the need inspected once a year. Gas tank before using the unit in a pressure vessel in use, should be "pressure vessel registration rules" requirement, the safety supervision agencies or departments authorized by the registration desk. Pressure vessel using the unit, should be in the process of rules and procedures in the post, clearly the pressure vessel requirements for safe operation, the contents of which should at least include: 1. tank operating process indicators (including the maximum working pressure, maximum or minimum working temperature); 2. tank positions operation of law (including opening and parking procedures and precautions); 3. The tank should focus on checking the operation of the project and the site of Qin Wei air compressor, running anomalies that may occur and measures to prevent, control and disposal procedures emergencies. Cottle Cottle compressor works single-stage compression screw compressor are parallel to each other by a pair of yin and yang rotor teeth together (or screw) rotates in the cylinder, the air between the rotor slots constantly produce periodic volume change, air is transported along the rotor axis from the suction side to the output side, to achieve screw air compressor intake, compression and exhaust the whole process. Air compressor inlet and outlet are on opposite sides of the housing, the female rotor groove and the teeth of the male rotor is driven to rotate the main motor. 2. Compressor Lubricant 2.1 2.2 rotary vane compressor reciprocating compressor reciprocating compressor provides a lot of outflow pressure capacities ranging from 1bar g to 1000bar g. Reciprocating compressor cylinder lubrication oil, crankcase parts, coils, pistons, valves and loading lever. Crankcase components include crosshead bearing, cross joint, crosshead guide and crank pin. Recent refrigeration applications indicate operating viscosity of less than 10 cSt the ISO15 lubricants can provide suitable lubrication. However, relying on the molecular weight and gas flow pressure compressor operating Cottle, processing and hydrocarbon gas reciprocating compressors classic use is ISO68-680 products. 2.3 a screw compressor, a centrifugal compressor through the high-speed rotation of the impeller compressor, the prime mover to transfer energy to the gas, the gas pressure and speed, the speed of the gas compressor in the fixation element can be converted to pressure energy. Mainly used to compress and transport gas. Working principle of the centrifugal compressor is a rear gas into the impeller of a centrifugal compressor, under the action of the impeller blades, while high speed rotation along with the impeller, while under the action of centrifugal force of rotation of the impeller outlet flow, and by the diffuser of the impeller effect, the pressure and kinetic energy are improved, the gas enters the diffuser, the kinetic energy is further converted into pressure energy, and then the gas through the corners, a reflux condenser into the lower-stage impeller is further compressed, so that the gas pressure to the desired process requirements.
