Abstract

The invention relates to the field of fire fighting equipment manufacturing, in particular to a submersible fire fighting pump joint using a new wear-resistant material. The main structure of the submersible fire fighting pump joint using the new wear-resistant material comprises a hemispherical joint body; a connecting hole is formed in an arc surface of the body so that the body can be connectedwith a water inlet pipe of a fire fighting pump; a plurality of water inlets are formed in the arc surface of the body; each water inlet is connected with an isolating pipe; each isolating pipe consists of an elastic soft section and an isolating ball body; according to the submersible fire fighting pump joint designed by the scheme, water bottom sludge sucked into the water inlets can be effectively reduced; meanwhile, the diameter of a water inlet strip on each isolating ball body is small, so that impurities in a water source can be filtered; and moreover, the new wear-resistant material is used, so that the wear to the body caused by the impurities in water is avoided, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of fire-fighting equipment manufacturing, in particular to a joint for a submersible fire-fighting pump using a new wear-resistant material. Background technique [0002] The fire pump has the characteristics of full sealing, no leakage, and corrosion resistance. It is widely used in environmental protection, water treatment, fire protection and other departments. The use of fire pumps needs to be considered comprehensively according to the process flow, water supply and drainage requirements. focus of attention. [0003] CN202418001U provides a fire pump provided with rollers, including a fire pump base and rollers. There are four rollers on the front and rear sides of the bottom of the fire pump base. Compared with the prior art, the utility model adds eight universal wheels coated with fireproof materials on the bottom of the fire pump base, so that the fire pump is more convenient to use in the fire scene with h...
