The Design of screw-type suction port at the air intake side can help the compression chamber of dental compressor machine fully inhale. Because the screw-type dental air compressor has no intake and exhaust valve groups, and the intake air of dental compressor machine is only regulated by the opening and closing of a regulating valve. When the rotor rotates, the cogging space of the main and auxiliary rotors is larger when it is transferred to the opening of the inlet end wall of the oilless air compressor. At this time, the cogging space of the rotor is communicated with the free air of the air inlet. Since all the air in the tooth groove is exhausted during the air exhaustion, the tooth groove is in a vacuum state at the end of the exhaust. When it turns to the air inlet, the outside air is sucked in and flows into the tooth groove of the main and auxiliary rotors along the axial direction. When the air fills the entire tooth groove, the end face of the intake side of the rotor turns away from the air inlet of the casing, and the air between the tooth grooves is closed.
At the end of the suction of the main and auxiliary rotors, the tooth peaks of the main and auxiliary rotors of the dentist dental medical compressor are closed with the casing. At this time, the air is closed in the tooth groove and no longer flows out, that is, the sealing process. The two rotors continue to rotate, their tooth peaks and tooth grooves match at the suction end, and the matching surface gradually moves to the discharge end.
During the conveying process, the meshing surface gradually moves to the exhaust end, that is, the gap between the meshing surface and the exhaust port gradually decreases, the gas in the tooth groove is gradually compressed, and the pressure increases, that is, the compression process of the wholesale oilless air compressor. At the same time of compression, the lubricating oil is also injected into the compression chamber and mixed with the chamber air due to the action of the pressure difference.
First of all, you have to judge what model your dental oil-free air compressor is. Is it a piston, screw or scroll oilless air compressor? If it can't be started, it means that it can't be started or there is no shutdown prompt. You can also concult your dental product manufacturer to make it clear.
When encountering this kind of problem, the first thing you have to check is the voltage and current of the oilless compressor. After confirming that there is no problem with both of them, we will consider whether the machine itself has a problem. If it is confirmed that it is indeed the problem of the machine after careful inspection, what we need to check at this time is the circuit, and the controller and the host must be considered. Basically, after the above steps, the problem that the oil-free air compressor cannot be started can be solved.
When an oil-free air compressor works intermittently, there is often insufficient air supply: this failure is usually caused by insufficient current and voltage connected to the oil-free air compressor. There is a buzzing sound when it starts up. This is because the low voltage makes the oil-free air compressor head work when the voltage is less than 200V. This problem will also cause the oil-free air compressor head to start frequently, causing the temperature to rise, triggering the circuit protection device and causing shut down, and when the temperature drops, the oilless compressor will restart again.
For users who often have this problem, our suggestion is to replace the current at work or install an automatic voltage stabilizer to solve it.
