Component Introduction


1. Perfect control system
It can automatically adjust the operating frequency according to the set pressure, only providing peak speed when needed in industry, meeting the requirements of different operating conditions, and further reducing energy consumption and maintenance costs. With a microcomputer control system, the operating status and parameters of the vacuum pump can be monitored remotely, and the causes can be analyzed and problems quickly solved based on remote fault warnings and alarms, providing technical support for the long-term reliable operation of the equipment.

2. Permanent magnet synchronous motor power system
The ultra-high-efficiency motor is equipped with precision bearings, low speed, low noise, stepless;
The large adjustment range brings greater energy-saving space.

3. Noise reduction system
In practical applications, the host exhaust will produce strong noise, which has a great impact on people's production and life, so it is urgent to control the noise. A high-efficiency silencer can reduce the noise emitted from the host to a reasonable range for environmental life.

4. Safety protection system
A complete set of safety protection components for the whole machine. When the exhaust temperature of the whole machine is too high, or the vacuum degree of the whole machine exceeds the set value, the solenoid valve in the protection system is opened to prevent damage to the host, and a simple structure is used to ensure the safe use of the host.

5. Heat dissipation system

Heat dissipation system
A safe and stable heat dissipation system controls the oil temperature within a certain range, ensuring that the oil temperature in the entire system is always at an appropriate temperature, so that the system runs more stably.

6. Host system
It adopts a new type of energy-saving screw rotor gear independently developed, which is more energy-saving and reliable. The vacuum-specific sealing structure design gives the pump a longer lifespan and reduces maintenance costs. The food-grade coating solution jointly developed by multiple units can greatly reduce gas loss, prevent rust and corrosion, and improve efficiency at the same time. The dry, oil-free cavity design can operate at a constant high pumping speed, with stable negative pressure unaffected by operating temperature. Replacing negative pressure Roots blower and water ring pump applications, with obvious environmental protection and energy-saving effects.

7. Cooling and lubricating oil system
The oil tank structure combines the oil mist separator and the oil pump motor into one, with a high degree of integration and small space occupied inside the box. In addition to preliminary separation through the oil mist separation core structure in the oil mist separator structure, a breathable cap is also added for a second mechanical separation, making the oil mist separation more thorough, and the oil content in the discharged air is lower, and the impact on the environment is smaller. At the same time, combined with the internal simple oil circuit system, the design of the whole machine is more concise and clear.
