PRODUCT details
airend
Twin-screw high-efficiency airend● Newly developed for industrial vacuum applications. Reliable, efficient and low noise. ● Screw technology is more efficient than other technologies (rotary vane, water ring, etc.).
Motor
Specialized permanent magnet motor ● Using high coercive force and high temperature resistant permanent magnets to ensure 150℃ without demagnetization. ● Built-in PTC temperature protection to prevent demagnetization caused by high temperature due to failure.
Specialized inverter
Specialized inverter
● Synchronous, easy frequency control, good dynamic response performance, can quickly respond to a wide range of adjustment and accurately regulate the vacuum degree. ● VSD regulation start. Smooth start. Reduce the impact on the grid.
Imported filters
Imported filters
● American imported filter. ● Equipped with pre-filter design. High dust capacity. 99% filtration efficiency @5micro. Fully guarantee the safe operation of the airend.
Lube oil cooling system

Lube oil cooling system

● Uses dedicated synthetic lubricant with a life expectancy of 8,000 hours.

● Lubricant cools the airend, which is then cooled by the cooler

Instrumentation and electronic control system

Instrumentation and electronic control system

● Using instrumentation and electrical control.

● Indication of exhaust temperature, oil/air separator tank pressure,system vacuum level.


Specialized inlet valve for vaccum application
Specialized inlet valve for vaccum application
● Ultra-low throttling loss. Contributing to the overall efficiency of the vacuum pump. ● Automatic adjustment of the valve  opening according to the load capacity to automatically maintain the system vacuum within the set range.
Oil/air separator tank

Oil/air separator tank

● Using similar design like air compressor. The oil content of exhaust air is less than 3PPM.

● Tangential air inlet design with baffle plate in the inner skirt to achieve cyclone separation and impact separation effect.

No-loss direct drive

No-loss direct drive

● Using motor direct drive. Rotor speed and motor speed consistent.

● The main motor is connected to the airend with a "C" flange to make the motor and the airend a rigid body and keep the axis in alignment.




ENERGY SAVING COMPARISON


Rotary vane pump solutions

SCR permanent magnet VSD oil-injected screw vacuum pump

Equipment situation 15 x Rotary vane pumps 4 x SCR1300VSPM
Pumping speed 300m³/H *8=2400m³/H 1300m³/H*2=2600m³/H

Total power of vacuum pump

7.5kw * 15=112.5kw 22kw*4=88kw
Deep freezer 15kw * 4=60kw Not required
Energy saving situation

Fixed speed rotary vane vacuum pump.Full load after running.

VSD screw vacuum pump. Frequency range of 12%~100%. Operation can achieve 25%~50% energy saving effect.

1 year operating power

(112.5kw+60kw)*24h*350days =1.45 million kWh

88kw*24h*350 days*70%=520,000 kWh

1 year power saving

/

VSD screw vacuum pump can save 930,000 kWh/year

1 year savings on electricity / 930,000 kWh * 0.7 = 650,000 RMB/year
Management The number of equipment is too many, and the maintenance workload of rotary vane pump is large. It takes up a lot of labor. The equipment runs stably and requires only regular maintenance, saving a lot of labor.
Service life / Screw vacuum pump equipment is stable and has a service life of 15~20 years.
