(3) a pressure switch. Rely on pressure changes of the air compressor to control intake valve solenoid pull-in control intake valves open and close Germany Burg air compressor, and further controls the motor. Can be set to a maximum pressure value Berg air compressor Qingdao to achieve this pressure Berg air compressor inlet valve closed, and sends a signal the motor stop delay, while another set minimum pressure value, down The pressure of the intake valve is turned on or restart the motor. Decrease in efficiency can be imagined, not to mention in its life cycle to be repeated several times frustrating. It can not be the main reason widely recognized by customers. There are more than three single-screw compressor fatal weakness. Sullair air compressor parts of these three vulnerabilities can not achieve a breakthrough to also talk about efficiency? Talk about energy conservation? Talk about life? Talk about the world? Because the compressor collision is certain to happen and therefore it is necessary to select the gear pair abrasion. And do not be like the twin-screw compressor choose the same stiffness as the strength of steel materials. Resistant soft touch material. This allows a single screw lost twin screw vice same powers as the main screw and gear. But only to take "round single-car, car insurance handsome homes' design methodology! Extend the service life of the gear in order to achieve the effect of pay. Only try to ease friction, touch.
