"Q & a series of technical problems of air compressor (six)" refer to: http://www.dg-zhihe.com/cn/newsshow.asp? Id=425

Small make up: the presence of air compressor, unloading problems?

Chi and Technology Master: air compressor loading, unloading control method is theair inlet switch control mode, the air inlet valve is closed to the pressure limit,compressor enters the light load, when the pressure in the lower limit of the inlet valve is opened, the compressor into full load operation. In view of this, the air compressorunder normal working conditions, moving machine parts motor speed will not changewith the change of the pressure, that is to say, the motor is running at the highestspeed rated condition, its opening and closing load depends on the intake valve.

Small make up: air compressor intake valve and exhaust valve problem

Chi and Technology Master: adjust the inlet valve by mechanical means, can not becontinuous adjusted the amount of gas, when the gas consumption constantlychanges, the air pressure can not stop the occurrence greatly shaken. Another gasprecision can not reach the process requirements. Then the frequent adjustment ofthe intake valve, will accelerate the wear of the intake valve, which affect the quality ofair compressor compressed air, increasing the amount of repair and repair costs.Frequent switching valve, leading to deflation valve durability decline, eventually will also affect the normal work of the compressor, bring a loss to production.

Small make up: air compressor unloading process, the pressure regulation is not correct the consumed energy; generally speaking, when the pressure reaches the value Pmax the maximum pressure, the air compressor is mainly through what way tobuck uninstall?

Chi and Technology Master: intake valve closing the motor in the idle state, while separating the compressed air tank venting excess. This approach leads to a lot of compressed air wasted, will cause a great waste of energy. The air inlet valve is closed to motor idling can make air compressor need not work, but the air compressor in an idle state or drive the screw back, so, the energy consumption of air compressorunload probably accounts for the air compressor under full load operation of 15%-20%; in short, the air compressor 15% time in the idle state, makes it hard. Sowith the compressor in the unloading air control method, air compressor motor has a great potential of energy saving.

Small make up: air compressor in the loading and unloading air control modecompared with the air compressor control system, mainly in what place can generate energy waste?

Chi and Technology Master: air compressor in the process of compressed air,compressed air pressure exceeded the minimum pressure value is the energy consumption of Pmin, compressed air pressure reaches Pmin, the original control mode causes pressure will continue to rise until Pmax. Then this process will bereleased to the outside world a lot of energy, a lot of loss leads to energy. When more than that of Pmin gas into the pneumatic components, the pressure after the valveafter decompression, the pressure will be reduced to close to Pmin position. This process also consumes energy.

Small make up: piston type air compressor according to exhaust pressure level can be divided into?

Chi and Technology Master: low pressure air exhaust pressure compressor ≤ 1.0MPa

Medium pressure air compressor discharge pressure < 10MPa 1.0MPa >

High pressure air compressor discharge pressure < 100MPa 10MPa >

Small make up: piston type air compressor is connected to an exhaust magnitude is divided into?

Chi and master the technology: 1m3 / min < small air compressor exhaust volume10m3 / min 

10m3 / min < medium air compressors ≤ 100m3 / min

Large air compressor exhaust > 100m3 / min

Exhaust air compressor suction state that free gas flow.

General provisions: the shaft power, exhaust pressure < 15KW ≤ 1.4MPa for miniature air compressor.

Small make up: piston type air compressor cylinder center line according to therelative position and the ground is divided into?

Chi and Technology Master: vertical air compressor -- cylinder center lineperpendicular to the ground layout.

Angle type air compressor -- cylinder center line forms an angle with the ground (V type, W type, L type).

Horizontal air compressor -- cylinder center line parallel with the ground, the cylinderis arranged in one side of the crankshaft.

The dynamic balance type air compressor -- cylinder center line parallel with the ground, the cylinder are symmetrically arranged on both sides of the crankshaft.

Small make up: piston type air compressor according to the structure characteristics of divided into?

Chi and master the technology:

Single action -- gas compression only in the side of the piston.

Double action -- the gas is compressed on both sides of the piston.

Water-cooled -- refers to the cylinder with the cooling water jacket, water cooling.

Air-cooled cylinder surface -- cast heat sink, air cooling.

Fixed -- air pressure unit fixed on the foundation.

Mobile -- air compressor on the mobile device to move.

Lubricating oil -- refers to the cylinder lubrication oil circulation lubrication, movement mechanism.

Oil free lubrication -- that no lubrication in cylinder, piston and cylinder is running dry,but the transmission mechanism is composed of oil circulation lubrication.

Oilless lubrication -- the cylinder drive mechanism were no oil lubrication.

Small make up: piston type air compressor working principle?

Chi and Technology Master: piston type air compressor is driven by a motor through a coupling directly drive the crankshaft belt pulley, drives the connecting rod and piston rod, the piston reciprocating motion in the compressor cylinder, suction, compression,complete discharge process, there will be no pressure or low pressure gas booster,and output to the pressure storage tank. Among them, piston, piston and the inner wall of the cylinder and cylinder cover working chamber volume variable, the crank and connecting rod driven by reciprocating motion, compressed in the cylinder tocylinder gas.

Small make up: the advantages and disadvantages of piston type air compressor?

Chi and master the technology advantages: piston air compressor has the advantages of simple structure, long service life, and easy to realize large capacityand high voltage output. Disadvantage is the vibration
