The power system adopts the international advanced precision casting turbo fan (air pump), wide pressure and dual frequency, high reliability, low noise, long life, and can work continuously for 24 hours.
Made of aviation aluminum, professional lathe, precise and solid, good heat dissipation, fireproof and corrosion-resistant. 100% pure copper coil, using international high-purity cathode copper; surface phosphating shot blasting, electrostatic spray paint, uniform color, no paint peeling, scratch resistance.
Cartridge filter, high filtration fineness
The filter system adopts cartridge filter, imported polyester fiber substrate, PTFE coating treatment, and the filtration accuracy of dust with an equivalent diameter above 0.3 microns is over 99%. For different working conditions, higher filtration accuracy and anti-corrosion Electrostatic, oil-proof and waterproof, high temperature resistant and other materials.
Pulse back blowing dust removal, the effect is remarkable
The dust removal method of the filter cartridge of the dust removal system adopts the pulse solenoid valve connected to the spiral nozzle pulse back blowing, the working pressure is 0.4-0.6MPa, and it can be used after connecting to the air source. ,
The pneumatic pulse blowback system consists of a cylinder, an electromagnetic pulse valve, a PLC controller, and compressed air. One end of the pulse valve is connected to the compressed air storage cylinder, and the other end is connected to the injection pipe. An exhaust valve is installed on the valve cover, and the exhaust valve is controlled by a pulse controller.
When there is no signal from the pulse controller, the pulse solenoid valve starts to work, and the dust removal is completed in about 0.1~0.3S for each injection, and it is the high-pressure air ejected at this moment that has a good dust removal effect. The air enters the filter cartridge at a high flow rate, causing the filter cartridge to expand rapidly, causing a shock vibration, which shakes off the dust attached to the filter cartridge, and the fine dust adsorbed on the surface of the filter material is shaken off into the dust hopper under the action of the airflow The pulse solenoid valve is automatically controlled by the pulse controller, and the pulse width and time interval can be adjusted freely, so that the cleaning efficiency is higher and more thorough, so as to protect the service life of the filter cartridge. The electromagnetic pulse valve adopts a double-diaphragm structure, which is sensitive in control and high in efficiency, and can be sprayed continuously for 1 million times or more than three years
Intelligent control system, convenient and energy-saving
The frequency conversion control system is designed with PLC, frequency converter, touch screen and pressure sensor, which can realize multiple automation functions. The motor adopts frequency conversion to start, which reduces the high current pressure of the power grid and has a long service life.
The principle of constant pressure control can be used to install a wind pressure sensor at the inlet of the pipeline, and carry out constant pressure control within a certain range according to the detected wind pressure data. A sensor can be installed at the fast connection of each vacuum port. When the sensor signal is detected, the host starts to run, and when all the signals disappear, the host automatically shuts down. According to the number of detected vacuum inlets, the frequency converter automatically adjusts the frequency to achieve the best parameter matching and dual effects of energy saving and environmental protection.
The pressure tank is designed and manufactured with 304 stainless steel pressure vessel
The pressure-bearing parts of the main body of the main engine are made of 304 stainless steel, and are designed and constructed according to the pressure vessel to ensure airtightness and airtightness. Beautiful appearance, strong acid and alkali corrosion resistance, high cleanliness, can be used in food, pharmaceutical and chemical industries. The whole machine adopts a semi-closed structure, which is convenient for the heat dissipation of the motor and the maintenance of the equipment. It is convenient to use and cost-effective.
Pressure rod unloading structure, practical and convenient
The stainless steel dust collection bucket adopts the pressure rod discharge structure. When the dust needs to be cleaned after the dust is full, you only need to lift the pressure rod up, and the dust collection bucket will naturally fall to the ground. Drag the dust collection bucket with casters to dump the dust, and the dust is completed Finally, just depress the pressure lever, which is convenient, quick and practical.
