Introduction to the principle of electric screw machine

One. The electrical control system of the microcomputer controller electric screw air compressor is the key system of the electric screw compressor. Its main function is to reduce the voltage and reduce the starting current when the three-phase asynchronous motor (capacity is greater than 10KW) is started, so as not to generate excessive power in the power supply line. Voltage drop to reduce the impact on the grid.

Talking about the advantages of compressor enthalpy increasing technology

Talking about the advantages of compressor enthalpy increasing technology The air-jet enthalpy-increasing compressor adopts two-stage throttling intermediate air-jet technology, and uses a flash evaporator to separate gas and liquid to achieve an enthalpy-increasing effect. This compressor jet enthalpy increasing technology has many advantages, as follows:

What happens if the air compressor uses three filters and one oil for an extended period of time

The "three filters and one oil" of the air compressor have a specified service life, which is generally replaced after 2000 hours of use. If you continue to use it beyond the service life, it will bring a lot of harm to the normal operation of the air compressor

How to deal with the faulty host refrigerant system of the compressor

How to deal with the faulty host refrigerant system of the compressor How to deal with a main engine refrigerant system where the compressor has burnt out or failed is a more serious and technically demanding problem than the production of a new main engine. However, it is often neglected by most of the technicians, and even the wrong concept is replaced if they think that it is broken anyway! It causes some disputes that the compressor quality is poor or others use it improperly.

Adjustment of main machine clearance of twin screw compressor

I repaired a main engine with locked rotor in the early stage. It is an EP200 model produced by Ingersoll Rand in 1997. Before I repaired it, Ingersoll Rand itself could not repair it. Because the main engine was severely deformed and the rotor and cavity Severe body adhesion.
