DHLV-Z series
The low-pressure permanent magnet dual-frequency two-stage compression screw air compressor boasts a specially designed secondary compression system and a low-pressure dedicated host.
It is equipped with an IE5-level permanent magnet synchronous motor for peak efficiency. The compressor features a low-pressure oil and gas separation system, ensuring minimal oil content.
Additionally, it comes with a silent centrifugal fan configuration, a dual-frequency design for the host fan, an enhanced cooler side suction top row design, a cold and hot partition system, and a user-friendly touchscreen microcomputer controller for real-time monitoring of operational status.
Product Features
■ Permanent magnet motor, save your electricity costs, IP54, B-level temperature rise is suitable for harsh environments such as large dust and high temperature;
■ Multiple noise reduction design, calculated according to noise theory, with special flame-retardant muffler cotton inside to reduce unit noise and provide a quieter environment
■ Special low-pressure cooler with high efficiency and low noise centrifugal fan, large cooling air flow, low noise, faster cooling effect, convenient cleaning and maintenance;
■ Low-pressure special cyclone inner and outer oil sub-barrel design, improve the initial separation efficiency, with special low-pressure oil sub-core, low pressure loss, better separation effect, lower air oil content, long service life;
■ Auxiliary oil supply system is added to the unit below 3bar to 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
■ Place electrical components and oil separation and filtration modules that are easily damaged by high temperature in the cold room, which improves the service life of the unit.
1. The unique design of the intermediate coolant spray curtain reduces the temperature of the air, and the compression process is close to the most energy-saving isothermal compression. In principle, the two-stage compression saves 5%~8% of energy than the single-stage compression;
2.Two-stage compression, small compression ratio, less leakage, bearing load is small, bearing life is greatly improved;
3.Adopt the design idea of "big rotor, big bearing, low speed", reduce noise and vibration, increase the life and stability of the main engine;
4.The rotor tooth surface is processed by grinding machine to create a high-precision rotor, which is the first guarantee of high efficiency and stability of the main machine;
5.The use of new asymmetric rotor tooth type, high-precision coordinate measuring machine comprehensive measurement, excellent quality.
1.Screw compressor special intake valve, the unit is easy to start, with automatic adjustment function, low flow rate, low pressure loss, reduce energy consumption, low intake noise;
2. Reliable minimum pressure maintenance valve, low pressure loss, accurate control, super fast return seat, to ensure that the user does not return the gas;
3.Temperature control valve (part) : mixed-flow temperature control valve: The unit is configured with mixed-flow temperature control valve to ensure that the unit is more convenient to start in a low temperature environment, and ensure the oil supply of the unit at any time; By controlling the oil supply temperature of the main engine, the unit is guaranteed to be in the best performance state.
1. Large color LCD touch screen, with good man-machine interface, touch screen with anti-miscontact and sleep function;
2. Customized vector inverter, perfectly matched with the motor, low frequency and high torque:
3. Fully monitor the parameters of the machine, including voltage detection, three-phase imbalance detection, over pressure, over temperature, etc., without special care;
4. Configure the internet of things, you can view the unit running status on the mobile phone;
5. Independent air duct design, suitable for various working conditions.
1.Adopt centrifugal fan, new separate flow cooling fan design, with special cooler, cooling effect is better, more energy saving;
2.Compared with axial fans, centrifugal fans have higher wind pressure and lower noise;
3.Frequency conversion fan control, constant oil temperature, prolong the service life of lubricating oil;
4.Due to high wind pressure, the cooler and filter are less likely to be blocked.
1.IP54 protection grade, more stable and reliable than IP23 in harsh environments;
2. Low temperature rise design, higher efficiency, extend the service life of the motor;
3. Use ceramic plated bearings to completely eliminate the influence of shaft current on bearings;
4.Made of rare earth permanent magnet material, the torque is large when starting and running, and the current is small when starting and running;
5.Reasonable magnetic field design, magnetic density distribution, energy-saving motor operating frequency range is wider, low running noise;
6. 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, which is conducive to protecting the mechanical equipment, reducing equipment maintenance and improving the reliability of the equipment.
1.The coupling is a torsional elastic coupling with fail-safe function. It can effectively damp and reduce the vibration and shock generated during operation.
2.The elastomer is only subject to pressure and can withstand greater load, and the drum teeth of the elastomer can avoid stress concentration.
1.The filtration area of the air filter exceeds 150% of the normal need, the inlet pressure loss is low, and the energy efficiency is good;
2.The oil filter is made of imported glass fiber material, and the rated capacity of the oil filter is ≥1.3 times the circulating oil volume, with high filtration accuracy and good durability;
3.Imported glass fiber oil core, good filtering effect, low pressure loss of oil core;
4.Three filter position design is reasonable, easy maintenance, reduce downtime.
