The XBC series of diesel fire pump sets is designed in accordance with GB6245-2006 "Performance requirements and test methods for fire pumps" and NEPA20 "Centrifugal fire pump installation." It is specifically developed to meet the needs of fire protection systems in environments where electric power may not be available during emergencies. These units are composed of a normal-pressure water tank, diesel fire pump, and pressure proportional mixer, making them ideal for use in oil depots, chemical plants, ports, and airports. The system ensures that when a fire occurs, the automatic control cabinet detects the signal and activates the diesel fire pump. This provides continuous water supply and foam generation through the pressure proportional mixer, enhancing firefighting efficiency. The performance range of the XBC series includes flow rates from 10 to 800 L/S and pressures ranging between 0.2 to 2.2 MPa, with rotation speeds of 1500, 1800, or 2400 r/min. Key features include three start functions (manual, automatic, and emergency), automatic operation based on pressure signals, and a comprehensive monitoring and warning system. The diesel engine is directly coupled with the pump, ensuring compactness and reliability. Additionally, the unit supports adjustable flow and pressure through mechanical or electronic speed regulators. The pressure proportional mixer is built to last, using corrosion-resistant materials and high-quality valves. The normal-pressure water tank is made of hot-rolled steel, with a maximum pressure resistance of 1.6 MPa. It also includes a diaphragm to separate water and foam effectively, minimizing waste. Technical parameters cover various models, each with specific flow rates, head, rotation speeds, and pump types. The equipment is suitable for diverse applications, providing reliable and efficient fire suppression solutions. With its advanced design and robust construction, the XBC series is an essential component in modern fire safety systems.
Pressure vessel steel plate covers a range of steel grades that are designed for use in pressure vessel, boilers, heat exchangers and any other vessel that contains a gas or liquid at high pressures.
Familiar examples include gas cylinders for cooking and for welding, oxygen cylinders for diving and many of the large metallic tanks that you see in an oil refinery or chemical plant.
There is a huge range of different chemicals and liquid that that stored and processed under pressure. These range from relatively benign substances such as milk and palm oil to crude oil and natural gas and their distillates to highly lethal acids and chemicals such as methylc. So of these processes need the gas or liquid to be very hot, whilst others contain it at very low temperatures. As a result there is a wide variety of different pressure vessel steel grades that meet the different use cases.
In general these can be divided into three groups. There is a group of carbon steel pressure vessel grades. These are standard steels and can cope with many applications where there is low corrosion and low heat. As heat and corrosion have more effect on the steel plates chromium, molybdenum and nickel are added to provide additional resistance.
