The invention discloses an impeller of a fire-fighting hydraulic system. The impeller comprises an upper cover plate, an impeller shell, a rotating shaft, a wheel disc, blades and a lower cover plate;the upper cover plate and the lower cover plate are fixedly connected with the impeller shell through bolts, a plurality of openings are formed in the side surface of the impeller shell, the rotatingshaft and the wheel disc are integrally formed, the rotating shaft is located in the center of the wheel disc and comprises a solid region and a hollow region, the solid region is away from the central axis of the rotating shaft, connecting openings are formed in the portions, at the two ends of the hollow region, of the rotating shaft, each blade comprises an upper blade and a lower blade, one end of each upper blade and one end of each lower blade are welded into the solid region, and through openings are formed in the other end of each upper blade and the other end of each lower blade. According to the impeller of the fire-fighting hydraulic system, by improving the inner structure of the impeller, a traditional single-blade type impeller is changed into the double-layer impeller, theblades are appropriately changed, the work efficiency is accelerated, and the structure is stable.
Description
technical field [0001] The invention relates to the field of impellers, in particular to an impeller of a fire hydraulic system. Background technique [0002] The function of the hydraulic system is to increase the force by changing the pressure. A complete hydraulic system consists of five parts, namely power components, actuators, control components, auxiliary components (accessories) and hydraulic oil. The hydraulic system can be divided into two categories : Hydraulic transmission system and hydraulic control system. The main function of the hydraulic transmission system is to transmit power and motion, and the hydraulic control system must make the output of the hydraulic system meet specific performance requirements (especially dynamic performance). The hydraulic system generally refers to the hydraulic transmission system, and the fire hydraulic system is An important example in the hydraulic system. [0003] The impeller not only refers to the disc equipped with mo...
