The invention relates to an improved design of a 493 engine cooling water pump, in particular to a high-efficiency 493 engine cooling water pump. The high-efficiency 493 engine cooling water pump is provided with a pump shell, a shaft bearing is arranged at the bearing position of the pump shell, and a transmission flange plate, a water seal and an impeller are arranged on the shaft bearing. The high-efficiency 493 engine cooling water pump is characterized in that a guide cone is installed at a water inlet of the impeller, a stud is arranged at the large end of the guide cone and is installedin a threaded hole in the end face of the shaft neck at the right end of the shaft bearing, the small end of the guide cone is extended to be installed at the water inlet of the impeller, no gap exists in a connecting web plate of a blade, an annular back plate is installed, the outer diameter of the annular back plate is equal to the outer diameter of the impeller, an inner hole is arranged in the middle of the annular back plate, and the diameter of the inner hole is equal to that of the water inlet of the impeller. The problems of large noise and low working efficiency of an existing cooling water pump of an internal combustion engine are solved. The design is mainly used for improving an existing 493 engine cooling water pump.
Description
technical field [0001] The invention relates to an improved design of a 493 engine cooling water pump, which is a high-efficiency 493 engine cooling water pump. Background technique [0002] The water intake method of the existing 493 engine cooling water pump is that water directly enters the impeller from the body. At this time, the water seal is set in the high-pressure area on the other side of the impeller water inlet. At present, most of the 493 engine cooling water pump impellers are made of steel stamping. Type impeller; the existing problems of the 493 engine cooling water pump in the prior art are: 1. The water directly entering the impeller from the body directly impacts the end face of the shaft-connected bearing and the joint of the impeller, resulting in vortex bands, cavitation, and the noise of the cooling water pump 2. Due to the inherent characteristics of the open impeller processed by steel plate stamping, the gap at the turning point of the blade makes t...
