Product Features
■ Durable and stable air end: two-stage integrated air end, third-generation asymmetric rotor technology; suitable for medium-pressure compression ratio matching, high volumetric efficiency; adopt heavy-duty bearings, and the rotor is well stressed; two-stage rotors are respectively passed gear drive, so that each stage of the rotor has the best linear speed; using a large rotor, low speed design, low noise and low vibration;
■ IE3 motor, save your electricity cost, IP54, B-level temperature rise is suitable for harsh environments such as large dust and high temperature;
■ Coupling connection, more energy saving;
■ Multiple noise reduction design, calculated according to noise theory, with special flame retardant muffler cotton inside, to reduce the noise of the unit and provide a quieter environment for use.
■ Independent air intake, reduce intake resistance, multi-function intake valve group, start without load, motor load is small. Use high-efficiency filters to effectively filter particulates in the air;
■ Centrifugal fan with high-pressure plate-fin cooler has high wind pressure, low noise, independent external suction, exhaust air upward through a specially designed air duct to prevent hot air from returning; plate-fin cooler has high heat exchange efficiency and internal pressure The loss is small, which can make the oil fully exchange heat, no heat zone;
■ The oil and air barrels developed professionally according to medium and high pressure conditions can achieve the best coarse separation effect under various conditions; after the second separation of the customized oil core, the final oil content of the air is not more than 3ppm;
■ The conventional maintenance parts (three filters) adopt openable door panels, the installation position is easy to replace, and the maintenance is more convenient
■ Specially designed main engine oil supply system to stabilize the oil supply pressure and ensure that the unit (especially the bearing) can get sufficient oil supply in the later period of long-term operation, the unit operates more stable and has a longer life.
■ High temperature shutdown protection;
■ Motor overload protection;
■ Overpressure safety decompression system;
■ Optimized shock absorption pad to reduce vibration and noise;
■ Dedicated control system, multi-channel pressure sensor and multi-channel temperature sensor to comprehensively detect the running state of the unit; the user interface is more friendly, the control is more accurate and reliable.
■ The unit is equipped with an Internet of Things system, which can monitor the machine status on the mobile phone.
Medium voltage two stage air end
1. Two-stage integrated design, oil mist spray cooling between stages, improve compression insulation efficiency; reduce the temperature of air, save compression power consumption.
2. Suitable for medium-pressure compression ratio matching, small leakage in the air end, and high volume efficiency.
3. The bearings adopt imported heavy-duty bearings to make the rotor's force better; the two-stage rotors are driven by helical gears respectively, so that each stage of the rotor has the best linear speed.
4. The third generation of asymmetric rotor technology, the tooth surface is processed by the German KAPP rotor grinder to create a high-precision rotor, which is the first guarantee of high efficiency and stability of the air end.
Permanent magnetic synchronous motor
1. IP54 protection level, more stable and reliable than IP23 in harsh environments.
2. Low temperature rising design, the motor temperature rising is less than 60K, the efficiency is higher, and the service life of the motor is extended.
3. Use ceramic plated bearings to completely eliminate the effect of shaft current on bearings.
4. Manufactured with rare earth permanent magnet materials, the torque during starting and running is large, and the current during starting and running is small.
5. Reasonable magnetic field design, magnetic density distribution, wider operating frequency range of energy-saving motors, and low operating noise.
6. Cooperate with the operation of the inverter to realize the soft start of the frequency conversion, avoiding the strong mechanical impact of the machine equipment when the motor is started at full pressure, which is beneficial to protect the machine equipment, reduce equipment maintenance, and improve the reliability of the equipment.
High-quality and efficient coupling
1. The coupling is a torsionally elastic coupling with failure protection function, which can effectively damp and reduce the vibration and shock generated during the operation.
2. The elastic body is only under pressure and can withstand greater loads. The drum-shaped teeth of the elastic body can avoid stress concentration.
Advanced and reliable electronic control system
1. Intelligent control system, with a good human-machine communication interface; high-quality electrical components are selected, and contactors are imported brands.
2. Develop special programs for the characteristics of medium pressure, with multi-channel pressure sensors and multi-channel temperature sensors, comprehensive detection of the running state of the unit, automatic control of the machine state, no need for special care.
3. Emergency stop function, there is a push-type emergency stop switch in a prominent position of the unit, which can be immediately stopped in an emergency.
4. Configure Internet of Things, you can check the running status of the unit on your mobile phone
5. Independent air duct design, applicable to various working conditions.
Silent centrifugal fan
1. The whole series adopts centrifugal fan, which is more efficient and more energy-saving.
2. Compared with axial fans, centrifugal fans have higher air pressure, lower noise and more energy saving.
3. Controlled by frequency conversion fan, the oil temperature is constant and the service life of lubricating oil is greatly extended.
4. Due to the high wind pressure, the cooler and filter are less likely to be blocked.
Three filters
Air filter: The filter area exceeds 150% of the normal need, the inlet pressure loss is low, and the energy efficiency is good;
Oil filter: A full-flow built-in pressure-retaining oil filter suitable for medium-pressure working conditions. The rated processing capacity of the oil filter is ≥ 1.5 times the circulating oil volume. The imported filter material and large excess design are used. The filter has high filtration accuracy and good durability.
Oil content: Adopt folding and winding combined oil sub-core for medium pressure working conditions, wide applicable pressure range, good separation effect, low operating pressure loss; use imported glass fiber material.
Inlet valve
Inlet valve: the medium-pressure special normally-closed disc valve is adopted, which has a check function, stable operation, high control of air volume, a noise reduction design, low cavitation noise and long service life.
Minimum pressure maintenance valve: medium pressure special valve, high pressure resistance, high temperature resistance, accurate opening pressure, stable pressure in the barrel, ultra-fast repositioning, strong sealing, ensuring no return of gas, low pressure loss and high efficiency.
Temperature control valve (part): Mixed-flow 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 all times; by controlling the oil supply temperature of the host to ensure that the unit is in Best performance.
Oil shutoff valve: Medium pressure dedicated normally closed valve, controlled by the head exhaust pressure. When starting, the valve opens quickly to ensure that the compressor is lubricated and warmed up as soon as possible; when stopped, the valve can prevent oil from spraying from the intake side.
