Main features of the product

1 Exclusive use of balanced pressure technology, the vacuum pumping efficiency is increased by 50% (optional).

Adopt the world-class brand Roots vacuum pump - EDWARDS (UK), Edwards Roots vacuum pump exclusively uses hydraulic clutch transmission technology, with balanced pressure technology, to ensure that the roots vacuum pump can start synchronously with the first-stage vacuum pump without causing motor overload , the pumping efficiency is increased by 50%.

2 High vacuum.

Two-stage or three-stage vacuum pump is used (two-stage vacuum pump is used for pumping capacity of 4,000 cubic meters and below, and three-stage vacuum pump is used for more than 4,000 cubic meters), and the ultimate vacuum can reach below 0.1Pa.

3 Highly stable and reliable.

Optional Atlas (Germany Laybold, British Edwards Edwards is a brand of Atlas) vacuum pump, Roots vacuum pump.

4 Unique environmental protection and energy saving technology.

When the vacuum degree of the container reaches the customer's set value, the vacuum pump above the second stage stops running, and the first stage vacuum pump runs to maintain the running vacuum, thereby realizing energy saving.

5 With liquid level protection.

The oil and gas separator is equipped with a liquid level sensor. When the PLC detects the liquid level, the vacuum unit stops running and sends an alarm message to prevent the vacuum pump oil from being polluted.

6 With power protection.

When the PLC detects that the power supply is out of phase, wrong phase or the voltage is too high or too low, the equipment enters the protection state and sends out an alarm message to prevent the vacuum from being damaged due to the reverse rotation of the motor.

7 Equipped with motor overload protection.

When the PLC detects that the motor current exceeds the set value, the device enters the protection state and sends out an alarm message to prevent the motor from being damaged.

8 Simple operation mode.

Using PLC intelligent control, the equipment starts and stops with one key, without manual intervention.
