1DKT-700CA high-power air filling pump with inflation explosion-proof boxCore functions and technical features

PLC automation control

Using industrial grade PLC as the control core, it supports a "one click" operation mode and can monitor inflation pressure, flow rate, temperature and other parameters in real time through a human-machine interface (HMI). PLC logic can achieve automatic start stop, pressure regulation, fault alarm, and safety interlock (such as opening the door to cut off the inflation circuit), ensuring safe operation.

High pressure air filling capacity

Taking DKT-330CA as an example, its gas filling capacity reaches330L/minCoverage of work pressure232bar/300bar/330bar(Customizable), suitable for fields with strict air quality requirements such as firefighting, diving, aerospace, etc., in compliance with the Chinese national standard GB/T 31975-2015 and the international EN12021 breathing air standard.

Explosion proof and safety design

Equipped with a double-layer explosion-proof inflation box, the inner layer uses 5mm steel plate to separate the gas cylinder placement area, and the outer layer is 10mm steel plate. The pressure relief hole design can guide the airflow to be discharged when the gas cylinder bursts, avoiding personal injury. In addition, functions such as door opening interlock, door closing self-locking, and venting muffler further enhance operational safety.

Efficient purification and cooling system

Adopting a two-stage air filtration system to remove impurities and moisture, the air-cooled design ensures long-term stability, and the noise level meets the ISO3746 standard, making it suitable for scenarios with high environmental requirements.

2、 Application scenarios

Emergency rescue and firefighting

To provide high-pressure breathing air for firefighters' air respirators, diving gas cylinders, etc., such as in the procurement project of fire protection facilities in the chemical park of Mianzhu Emergency Management Bureau, PLC controlled inflation pumps are used to ensure the reliable operation of rescue equipmentChina Government Procurement Network.

Industrial and specialty gas filling

Suitable for high-pressure gas filling in fields such as petroleum and petrochemical, aerospace, etc., such as providing compressed air that meets standards for pressure vessels and testing equipment.

Vehicle and Mobile Operations

Some models support gasoline engine drive and can be flexibly deployed in outdoor or mobile work scenarios to meet temporary inflation needs.

3、 The key role of PLC control system

Precise pressure control

Real time adjustment of inflation speed through PID algorithm to avoid pressure fluctuations causing damage to gas cylinders, especially suitable for safe filling of high-pressure containers such as carbon fiber cylinders.

Data monitoring and recording

PLC can integrate sensor data such as pressure, temperature, and filtration status, and display or upload it to the cloud through HMI for remote monitoring and preventive maintenance. For example, IoT PLC technology can support device status warning and energy consumption optimization.

Safety Interlocking and Protection

Built in multiple safety logics, such as prohibiting door opening during inflation and automatic shutdown when pressure exceeds the limit, comply with industrial safety standards (such as ATEX explosion-proof certification).
