Product Description

Product Description

HY(V)-Z Series Medium Voltage Permanent Magnet Variable Frequency Screw Air Compressor

01.Advanced Medium Voltage Dual Stage Mainframe
1. Two-stage integrated design, oil mist spray cooling is used between stages, which reduces the temperature of the air, and the compression process is close to the most energy-saving isothermal compression. In principle, two-stage compression saves 5%-8% of energy compared to single-machine compression ;
2. It is suitable for the compression ratio matching of medium voltage, the leakage in the main engine is small, and the volumetric efficiency is high;
3. The bearing adopts imported heavy-duty bearing, which makes the force of the rotor better; the two-stage rotors are HYiven by helical gears respectively, so that each stage of the rotor has the best linear speed;
4. The third-generation asymmetric rotor technology, the tooth surface is processed by the German KAPP rotor grinder, creating a high-precision rotor, which is the first guarantee for the high efficiency and stability of the host.

02.High efficiency permanent magnet synchronous motor
1. IP54 protection grade, which is more stable and reliable than IP23 in harsh environment;
2. Low temperature rise design, higher efficiency, and extended the service life of the motor;
3. Use ceramic plated bearings to completely eliminate the influence of shaft current on bearings;
4. It is made of rare earth permanent magnet materials, with large torque and small current during startup and operation;
5. With reasonable magnetic field design and magnetic density distribution, the working frequency range of energy-saving motors is wider and the operating noise is low;
6. Cooperating with the operation of the frequency converter, the frequency conversion soft start is realized, which avoids the strong mechanical impact of the machine and equipment when the motor is started at full pressure, and is conducive
to protecting the mechanical equipment, reducing equipment maintenance and improving the reliability of the equipment.

03.Special valve group
1. Intake valve: It adopts a special normally closed butterfly valve for medium voltage, with a non-return function, stable operation, high precision of air volume control, built-in noise reduction design, low cavitation noise and long service life;
2. Minimum pressure maintenance valve: special valve for medium voltage, high pressure resistance, high temperature resistance, accurate opening pressure, ensuring stable pressure in the barrel, ultra-fast return to seat, strong sealing, ensuring no backflow of gas, low pressure loss and high efficiency ;
3. Temperature control valve: The unit is equipped with a mixed-flow temperature control valve to ensure that the unit is more convenient to start in a low temperature environment, and to ensure the oil supply of the unit at any time; by controlling the oil supply temperature of the main engine to ensure that the unit is in the best performance state;
4. Oil cut-off valve: special normally closed valve for medium voltage, controlled by the exhaust pressure of the machine head. When starting up, the valve opens quickly to ensure that the compressor is lubricated and warmed up as soon as possible; when shutting down, the valve prevents oil from being ejected from the intake end.


04.Advanced and reliable electric control system
1. Large-size color LCD touch screen, with good man-machine communication interface, touch screen with anti-mistouch and sleep function;
2. It adopts double frequency conversion system, which is more energy-saving. The frequency converter and the motor are perfectly matched, and the low frequency and high torque can output 180% of the rated torque;
3. According to the characteristics of medium voltage, a special program is developed, with multiple pressure sensors and multiple temperature sensors, which can comprehensively detect the operating status of the unit, and automatically control the machine status without special care;
4. Configure the Internet of Things, you can check the operating status of the unit on the mobile phone;
5. Independent air duct design, suitable for various working conditions.

05.Silent centrifugal fan
1. Adopt centrifugal fan, brand-new separate radial cooling fan design, with special cooler, better cooling effect and more energy saving;
2. Compared with axial flow fans, centrifugal fans have higher wind pressure and lower noise;
3. Using variable frequency fan control, the oil temperature is constant, prolonging the service life of lubricating oil;
4. Due to the high wind pressure, the cooler and the filter are less likely to be blocked.

06.High quality triple filter

1. The filtration area of the air filter exceeds 150% of the normal requirement, the inlet pressure loss is low, and the energy efficiency is good;2. The oil filter adopts a full-flow built-in pressure-bearing oil filter suitable for medium voltage conditions. The rated processing capacity of the oil filter is 1.3 times the circulating oil volume. The imported filter material and the design scheme of large margin are selected, which has high filtration precision and good durability.
3. The oil is divided into special customized oil, which is designed and developed for medium-pressure working conditions, with wide applicable pressure range, good separation effect and low operating pressure loss; imported glass fiber material is selected;
4. The design of the three filter positions is reasonable, the maintenance is convenient, and the downtime is reduced.

07.High quality and efficient coupling
1. The coupling is a torsional elastic coupling with a failure protection function, which can effectively damp and reduce the vibration and impact generated during operation;
2. The elastic body is only under pressure and can bear a larger load, and the drum-shaped teeth of the elastic body can avoid stress concentration.   

Overall energy saving of products

Compared with power frequency air compressor, energy-saving variable frequency air compressor has practical significance.
1. The pressure control of the inverter air compressor is accurate. It can quickly respond to pressure changes, adjust the speed of the permanent magnet motor, control the pressure fluctuation range within 0.1bar, stabilize the pipe network pressure, provide the necessary air volume with the most reasonable power, and reduce excess energy consumption.
2. The variable frequency air compressor adopts the method of variable frequency starting, which eliminates the peak current of the star-delta starting, and starts smoothly. Reduce the starting power, reduce the impact on the grid and equipment, and reduce equipment operating noise.
3. The frequency conversion control is more excellent than the ordinary throttling control. The adjustment range of the flow rate is larger, and with the high-efficiency permanent magnet motor, the energy saving effect is more significant at low percentage flow rate.
4. Most of the cost in the life cycle of the air compressor is generated by the electricity it consumes. The power consumption of the compressor is closely related to the air used on site. The inverter air compressor can not only ensure smooth and guaranteed production, but also save considerable electricity bills and achieve a win-win situation for the enterprise.

Product application scenarios
Mining equipment: used for high-pressure blasting mining, HYiving all kinds of pneumatic machinery.

Baling machine: the air compressor is used in the pneumatic baling machine. After compressing the air, the piston of the cylinder is pressed down to HYive the vibrator to move quickly, so that the overlapping part of the packing belt has a hot-melt effect.

Product case

An oil field borders the Bohai Sea in the East, the central Hebei Plain in the west, Shandong Province in the southeast, and the junction of Tianjin and Tangshan in the north. It spans 25 districts, cities and counties in Tianjin, Yichang and Shandong provinces. The exploration and development construction began in January 1964, with a total exploration and development area of 18716 square meters. The oil headquarters is located in Tianjin Binhai New Area, the key development and opening-up construction area of the national "Eleventh Five Year Plan". It is 190 kilometers away from Beijing, 40 kilometers away from Tianjin Xingang and 70 kilometers away from Tianjin International Airport. It has a superior geographical location, developed sea, land and air transportation and convenient traffic. It is an important part of the Bohai rim economic circle. HY-45z from Huayan company is mainly used for pipeline purging and gas supply.
