Description
Technical Field
The invention relates to an improved design of a 493 engine cooling water pump, in particular to a 493 engine flow guide type cooling water pump.
Background
The impeller of the existing 493 engine cooling water pump is an impeller formed by punching a steel plate, and the impeller is limited by a punching process and has the following problems:
1. the punched impeller is formed by turning the blades, the radial plate is defective, the impeller is generally fully opened, the flow channel in the impeller is communicated with the volute chamber, and hydraulic losses such as water leakage, backflow, vortex and the like are easily caused.
2. The shaft shoulder of the punch forming impeller is generally provided with steps, is not smooth and is easy to generate hydraulic loss such as impact and the like.
Disclosure of Invention
The invention aims to solve the problems of low working efficiency and poor reliability of the existing 493 engine cooling water pump, and provides a 493 engine flow guide type cooling water pump. The specific scheme of the invention is as follows: the utility model provides a 493 engine water conservancy diversion type cooling water pump, it has the pump case, is equipped with bearing position, water seal position, round platform body, spiral runner, mounting hole, water leakage groove and seal groove on the pump case respectively, installs the hub connection bearing in the bearing position department of pump case, installs the transmission ring flange on the left axle journal of hub connection bearing, and the water seal is installed in the right axle journal middle part of hub connection bearing and the water seal position department of pump case, installs the impeller on the right axle journal, the impeller be precision casting water conservancy diversion type semi-open impeller, characterized by: the impeller be equipped with the shaft shoulder, the radials of umbrella face shape, be equipped with the antecurvature blade of eight equipartitions on the radials, be equipped with the hole of loudspeaker shape in the radials, be equipped with two balanced holes of axis symmetry on the radials.
The invention has the beneficial effects that:
compared with the existing 493 engine cooling water pump, the precisely cast flow-guiding semi-open type impeller provided by the invention is provided with the smooth umbrella surface radial plate and the smooth cone for flow guiding, so that the problems of water flow blockage, large backflow vortex vibration, poor connection rigidity, low working efficiency and the like caused by punch forming impeller radial plate defects and step shaft shoulders are solved, and the problems of low working efficiency, unstable performance, poor connection reliability and the like of the existing water pump are well solved.
