Problems solved by technology

In many cases, fire-fighting facilities need to draw water from natural water sources, especially in coastal or offshore areas. Long-axis pumps are often used as fire pumps. However, the high-salt and high-corrosion nature of seawater often causes extreme damage to the pump body and pump shaft. Severe corrosion limits the application of long shaft pumps in the field of fire protection

Abstract

The invention relates to the field of firefighting equipment manufacturing, in particular to a diesel engine long shaft fire pump adopting a new material resistant to seawater corrosion. The diesel engine long shaft fire pump mainly comprises a fire pump body, a diesel engine and a control cabinet. The fire pump body is a long shaft single-stage centrifugal pump. The diesel engine is connected with the fire pump body through a pump shaft and can drive the fire pump body to work. The diesel engine long shaft fire pump is characterized in that the fire pump body and the diesel engine are arranged side by side, and the pump shaft is divided into several sections. The long shaft fire pump has the beneficial effects of being convenient to start, fast in water output, low in weight and reliablein work. A shell, an outlet pipe and an flow passage component of the fire pump are all made from a new material resistant to seawater corrosion with modified acrylic resin as a carrier, so that the product has a better seawater corrosion resisting effect, and is suitable for working under the seawater corrosion condition for a long time.

Description

technical field [0001] The invention relates to the field of fire-fighting equipment manufacturing, in particular to a diesel engine long-axis fire pump using a new seawater corrosion-resistant material. Background technique [0002] Long shaft pump refers to the collective name of pump products with relatively long pump shafts. my country stipulates that long shaft refers to a series shaft system consisting of a single shaft or multiple shafts that require three or more supporting points. Long-axis pumps are mainly used in various fields such as farmland drainage and irrigation, flood control, drainage, sewage treatment, power stations (coal-fired power plants, nuclear power plants, energy storage power plants, tidal power plants), cooling systems, and fire protection. [0003] CN102400940A discloses a long shaft pump, which includes a plurality of guide bearing parts composed of guide bearing sleeves and guide bearings, and the material of the guide bearings is polyether e...
