Abstract
The utility model relates to a pump piston, in particular to a pump piston using for cleaning machine, and is characterized in that: the surface is a nitrided layer of 0.05 - 0.15mm thick, and the connection site of a cylindrical form 1 and a top end 2 is a circular arc 3. The utility model has the advantages of prolonging the service life of the seal ring, as well as abrasion resistant and corrosion control, and producing the process, saving the alloy steel, promoting the product quality and work efficiency and reducing the cost.
Description
Technical field
The utility model relates to a kind of water piston, particularly the washing machine water piston.
Background technique
Now washing machine is the right angle with the cylindrical of water piston and jointing place, top, piston seal ring easy to wear in push-and-pull work like this, and it is big to make it the component loss.In order to improve the wear-resistant hardness of outer surface, after the piston moulding, slot again hardfacing alloy steel car circle, polishing again, the many but also waste material of operation not only, inefficiency, cost height.
Summary of the invention
The purpose of this utility model is to overcome the prior art deficiency and designs a kind of new washing machine water pump piston.
The purpose of this utility model is to finish by following design proposal, and washing machine water pump piston face is the nitride layer of 0.05～0.15mm, cylindrical 1 with 2 jointing places, top be circular arc 3.
Advantage of the present utility model:
The utility model is owing to cylindrical and jointing place, top are circular arc prolongation seal ring working life, and there is the nitride layer of 0.05～0.15mm on the surface, not only can reach wear-resistant but also anti-corrosion.

Specific embodiments
In conjunction with the accompanying drawings the utility model embodiment is elaborated:
Accompanying drawing 1 washing machine water pump is made into circular arc 3 with piston cylindrical 1 and 2 jointing places, top, prolongs seal ring working life; The surface is to handle the nitride layer that forms 0.05～0.15mm through bath nitriding, not only can reach wear-resistant but also anti-corrosion, and technique process reduces, and saves alloyed steel, increases work efficiency, and reduces cost.Piston connects cylinder pin hole and utilizes advanced technologies to process, and the deviation of its vertical concentricity reaches-0.01mm-0mm, and when its technology was moved piston in piston sleeve, frictional force was little, thereby had improved the working life of product.
Claims (1)
