The design concept of EVP Rotary Screw vacuum pump allows customers to operate the design principle with one button. EVP vacuum pumps are not only sturdy and durable, but also can easily achieve the best performance in the working pressure section required by the customer.
Performance and structural characteristics of products
Screw pump head
EVP independently developed and produced the main engine with imported bearings, innovative bearing arrangement and fixed radial bearing and thrust bearing, which has increased the service life compared with the standard arrangement. The bearing load time is shortened in the same proportion, so as to maximize the engine life. The bearing adapts to the changing load and provides high flexibility and efficiency. Matching IP54 motor with full enclosure can ensure continuous operation in dust and humidity environment, with excellent reliability.
Screw Pump Rotor
It adopts the most advanced screw processing technology in the world, KAPP120 Rotor Grinder, with high precision, reliable performance and low energy consumption. Permanent magnet variable frequency drive technology and integrated integrated design motor, the efficiency of EVP+ permanent magnet variable frequency is greatly improved, thus achieving energy saving of about 40-50%, and reducing life cycle costs. The super oil and gas separation performance can better improve the quality of exhaust gas emission and reduce the impact on the environment. At the same time, it can also avoid the fuel injection that often occurs in conventional oil pumps.
Integrated installation
The whole machine is composed of host, motor, electric control, lubrication system, muffler system, frame, instrument, valve, etc. All functional components are integrated on an integral base, which can be installed and moved as a whole. The production and assembly of the equipment are completed in the factory, and the on-site installation workload is small. You only need to complete the connection of the interface pipe and the external electrical connection.
Intelligent Control System
The EVP rotary screw vacuum pump is equipped with the latest operation control system. The host uses the control screen as a man-machine interface to realize man-machine dialogue. The Chinese/English operation display system is simple and intuitive.
Automatic control, provide all-round maintenance information of rotary screw vacuum pump, realize maintenance reminder, can print pressure curve, can record historical alarm, and facilitate users to analyze the actual parameters of the process system. And provide monitoring signals to the host computer. No special guards are required, which reduces labor costs and improves operational efficiency.
PLC Automatic control, simple operation, vacuum pressure display, temperature display, operation record, automatic alarm!
Overall design of cold chamber and hot chamber
The internal structure of Screw vacuum pump is divided into cold chamber and hot chamber, so that the motor, control part and air inlet are in the cold chamber, so as to ensure that the motor and controller are in a relatively low temperature.
Good working environment, and the air intake can absorb fresh cooling air as far as possible, so as to ensure high efficiency (when the suction temperature increases by 5 ℃, the efficiency decreases by 2%); Integrated Variable Frequency Converter Drive:
1.Electrical cabinet with fully integrated frequency converter and control panel: no additional engineering and installation required
2.Specially selected driving parts: accurate parameter setting
3.Achieve maximum efficiency
4.When the gas demand can not reach the maximum value, there is no need to vent
5.Optimization of component selection
6.Reduce installation cost
