Abstract
The invention provides a piston groove modifying technology, and modified pistons can run for a long time and old pistons can be repeatedly used. The technology comprises the following steps: reprocessing an original piston with irregularly deformed piston groove due to long-term usage and circularly amplifying the piston groove in a neck direction so that the irregular part of the piston groove is processed to be regular; and then, processing a suitable piston ring according to the detailed modifying size. The invention decreases the production cost, prolongs the service life, further improves the sealing performance, improves the compression power and accordingly reduces the electricity consumption, and the like.
Description
Affiliated technical field
The invention belongs to field of machining and machinebuilding technology, a kind of specifically piston groove transformation technology.
Background technology
Compressor is the capital equipment in the Ammonia Production, the heart that is known as synthetic ammonia, compressor piston is because the piston groove wearing and tearing are very fast, for improving compression efficiency, have to the piston of serious wear is changed, and the piston that changes can only be worked as waste product and sold, because the price of piston is higher, caused serious fund waste to enterprise, made production cost high.
Summary of the invention
The invention provides a kind of piston groove transformation technology, improved piston can move for a long time, and waste and old piston is reused.
The object of the present invention is achieved like this: will originally cause the piston of piston groove irregular deformation to be processed again because of long-term the use, piston groove is carried out neck to expansion along hoop, irregular portion on the piston groove is divided through processing change rule, then according to the suitable piston ring of concrete transformation dimensioned.
The invention has the beneficial effects as follows: reduced production cost, improved service life, sealing property further improves, and has improved compression horsepower, the corresponding power consumption etc. that reduced.
Be described further below in conjunction with embodiment
One section piston of compressor is owing to use for a long time, and the piston groove abrasion deformation causes piston ring often to rupture, and is steady production, has to renew piston.After old piston was changed, we went to bed piston and transform, and changed groove width into 16 centimetres by 14 centimetres, and piston ring also carries out corresponding transformation.Be applied on the compressor after having transformed.Through the operation of some months, with transform before the piston ratio, improved piston, be sealing property should service life all will than before transforming.
Claims (1)
1, a kind of piston groove transformation technology, it is characterized in that, cause the piston of piston groove irregular deformation to be processed again original because of using for a long time, piston groove is carried out neck to expansion along hoop, irregular portion on the piston groove is divided through processing change rule, then according to the suitable piston ring of concrete transformation dimensioned.
