Problems solved by technology

But there is an essential part in all water pumps - the impeller, which provides flow force for the liquid by rotation, so as to realize the delivery of the liquid. However, due to the different environments and purposes of the pump, the fluid delivered by the pump It is not the same as liquids. There are many liquids and fluids that will cause damage to the water pump. Since the guide impellers in the water pump are mostly made of metal materials or rubber materials, the guide impellers are subjected to sand and hard when transporting liquids or fluids. The possibility of friction such as objects is also greatly increased. If the guide vane wheel of the water pump is rubbed, it will be damaged after a period of time. Once the guide vane wheel is damaged, it will directly affect the delivery capacity of the pump.

Embodiment 1

[0023] A water pump guide impeller with high wear resistance and a processing method thereof, comprising the following steps:

[0024] 1. Grind the surface of the cast guide impeller until the surface is smooth and has no burrs;

[0025] 2. Put the polished guide impeller into the high wear-resistant treatment solution for soaking. When soaking, completely immerse the guide impeller in the high wear-resistant treatment solution, and heat up the high wear-resistant soaking solution. When the high wear-resistant soak When the liquid temperature rises to 70-80°C, stop the temperature rise, and then keep the constant temperature for 2-3 hours. When soaking, turn the guide impeller every 0.5 hours. Flip in the state;

[0026] 3. After soaking, take out the guide impeller, hang it in a ventilated place, and let it dry naturally;

[0027] 4. Send the dried guide impeller into the sterilization room for spray sterilization. During spray sterilization, use diluted metalworking fluid ...

Abstract

The invention discloses a water pump guide blade wheel having the high wear-resisting property and a machining method of the water pump guide blade wheel, and relates to the technical field of water pump production fittings and water pump machining. The machining method comprises the following steps that a guide blade wheel is polished, and is soaked in a highly wear-resisting treatment fluid, then the guide blade wheel is aired after the soaking, and the guide blade wheel is subjected to spraying sterilization, secondary soaking and constant temperature treatment. After the guide blade wheel is soaked in the highly wear-resisting treatment fluid, a film can be laminated on the surface of the guide blade wheel and the film can resist collision and scratching of a hard object in a fluid, and prevents such kind of fluid having the friction ability from damaging and destroying the surface of the guide blade wheel, so that the highly wear-resisting property of the guide blade wheel is improved, the guide blade wheel is free from erosion and destruction of various fluids in the long-term use process, normal operation of conveying work of a water pump is ensured accordingly, and the service life of the water pump can be prolonged and the working efficiency of the water pump can be improved advantageously.

Description

Technical field: [0001] The invention relates to the technical field of water pump production accessories and processing thereof, in particular to a water pump impeller with high wear resistance and a processing method thereof. Background technique: [0002] A water pump is a machine used to increase the pressure of a liquid to make it flow. It is a device used to move a liquid or a special fluid medium, that is, a machine that does work on the fluid. Water pumps have different purposes, different conveying liquid media, different flow rates and head ranges. Therefore, of course, their structural forms are also different, and their materials are also different. However, there is an essential part in all water pumps - the vane wheel. The vane wheel provides flow force for the liquid by rotating, so as to realize the delivery of the liquid. However, due to the different environments and purposes of the pump, the fluid delivered by the pump It is not the same as liquids. There...
