Abstract
The present invention provides a method for modifying an oiled air pump into an oil-free air pump. The method adopts a novel pump body whose bore radial dimension is enlarged, a rotor whose diameter is enlarged and a wide and thick slide piece whose dimension is enlarged. Thereby, the air pressure generated by an air pump under the condition of no oil reaches the air pressure generated by an oiled air pump. The profit brought by an oil-free air pump is obtained, and simultaneously the present invention solves the problem that a new oil-free air pump has to be bought for replacing the oiled air pump so as to cause various waste.
Description
Technical field
The present invention relates to a kind of method that will have the oil gas pump to be adapted as no oil gas pump in the printing industry.
Background technique
At present, the air pump of using in the printing industry mainly is divided into two kinds of oil gas pump and no oil gas pumps.Have the oil gas pump in production practices, to have following problem:
1, complex structure causes having the parts of the low needs maintenance of oil gas pump reliability many, and engineering time is long, the maintenance technique complexity.There is the oil gas pump to comprise motor, motor connected element, radiation fan, the pump housing, rotor, slide plate, oil-way system, filtering gas bag, regulate parts such as gas bag, oil pump body assembly.
2, oil spout, leakage of oil.Owing to comprise oil-way system, fluid oil ceaselessly flows in system under the oil pump body rotor drives simultaneously, and all can there be poorly sealed phenomenon in various degree in the long-time running of process of the component joint, many places of system, and therefore, oil spout, leakage of oil become universal phenomenon.
3, the pressurized gas of Chan Shenging are unclean.Be discharged into the operation area after the filtration of the high-pressure oil gas mixture that in the oil gas pump pump housing is arranged, produces through chimney filter and filter screen.Chimney filter and filter screen itself just can not leach the fluid in the oil gas mixture fully, through behind the long-play, the filtering effect of chimney filter and filter screen can further reduce, directly be discharged into the operation area through the gas that still contains the part greasy dirt after filtering, quality to printing has a negative impact, simultaneously, air is polluted.
According to the oil gas pump is arranged, no oil gas pump has following advantage:
1, simple in structure, thereby make that the low parts of maintenance that need of no oil gas pump reliability are few, engineering time is short, and maintenance technique is simple, and user oneself can keep in repair.
2, there are not oil spout, oil leakage phenomenon.Owing to there is not oil to flow into the rotation that participates in producing air pressure in the pump housing, there is not oil-way system simultaneously yet, therefore there is not the phenomenon of oil spout, leakage of oil yet.
3, Pai Fang pressurized gas do not contain greasy dirt.Same owing in whole no oil gas pump produces the process of pressurized gas, do not have oil directly to sneak into, therefore do not have the pressurized gas that the oil gas pump gives off and more clean, very low to the pollution of environment.
As fully visible, according to the oil gas pump is arranged, no oil gas pump has simpler structure, thereby, make that the maintenance cost of no oil gas pump is cheaper, there is not the speciality that the oil gas pump does not have oil spout, oil leakage phenomenon simultaneously, make it aspect environmental protection, have more superiority.Just because of there are not many advantages that the oil gas pump has, therefore used widely.
But,, can only buy new no oil gas pump if want to use no oil gas pump for numerous users that bought the oil gas pump.This needs the user to pay the waste that the new no oil gas pump of the original purchase of high one-tenth causes fund on the one hand; On the other hand, the parts of the most operational excellences of oil gas pump were arranged originally,, can only discard, caused the waste of assets as motor, fan casing, base etc.
Summary of the invention
The invention provides a kind of method that will have the oil gas pump to be adapted as no oil gas pump, thereby change the problem of the various wastes that the oil gas pump causes obtaining to have overcome when no oil gas pump brings interests the new no oil gas pump of necessary purchase.
The present invention includes following steps:
A, dismounting have the pump housing, end cover, off-load ring, little slide plate, slide plate, rotor, end cap, bearing, waveform circle, one-level chimney filter, secondary chimney filter, one-level filter screen, secondary filter screen and the oil pump body assembly on the oil gas pump;
B, replace original pump housing with the new pump housing, the new pump housing is the interior thorax with increased diameter size according to the characteristics of original pump housing;
C, replace original rotor with new rotor, new rotor is that root diameter increases according to the characteristics of original rotor, and epitrochanterian depth of groove increases, recess width increases the 3.5-4.5 millimeter;
D, replace original slide plate with new slide plate, new slide plate is that wide increase, thickness increase according to the characteristics of original slide plate.
The scope that the inner thorax diameter size increases among the step B of the present invention is the 15-18 millimeter.
The scope that new root diameter increases among the step C of the present invention is the 9-23 millimeter, and the scope that epitrochanterian depth of groove increases is the 7-10 millimeter, and the scope that recess width increases is the 3.5-4.5 millimeter.
The scope that new slide plate width increases among the step D of the present invention is that the scope that 7-10 millimeter, thickness increase is the 3.5-4.5 millimeter.
The present invention also need original have to change the outfit on the oil gas pump possess the end cap of bigger aperture axis.
The present invention also need have a ball bearing that changes the outfit on the oil gas pump original.
The present invention also need original have install shelves lid on the oil gas pump additional.
Technique effect: oil gas pump pump housing rotor is arranged when rotating, because fluid has viscosity, slide plate can drive fluid and rotate in the pump housing.In rotation process, arbitrary slide plate is clogged by fluid away from the gap between the thorax wall in the outer end of rotor shaft and the pump housing, and the air between any two slide plates can not revealed, thereby the unit time produces highpressure from a large amount of gases of pump housing output in limited space.And do not have the oil gas pump because in rotation process, arbitrary slide plate is away from having the gap between the thorax wall in the outer end of rotor shaft and the pump housing, air between any two slide plates all can be revealed, thereby the no oil gas pump that under equal operating condition, has same rotor size, the gas flow of unit time from pump housing output is less than the gas flow that the output of oil gas pump is arranged, thereby the air pressure of output also will be lower than the oil gas pump is arranged.
For the air pressure that makes the no oil gas pump output after the repacking reaches the air pressure that has oil pump to produce, the present invention adopts and adds the imperial palace bore to the new pump housing of size, the rotor of diameter increase and the slide plate that wide, thick size increases, and makes the air pressure that air pump produces under no oily situation reach the air pressure that has oil pump to produce.
Slide plate on the no oil gas pump pump housing internal rotor is to be made by graphite, in rotation process, slide plate contacts with thorax in the pump housing, the fine powder that comes off is filled out and has been matched the small recess in interior thorax surface, through running after a while, interior thorax surface becomes smooth, to the frictional force minimizing of slide plate, plays lubricated effect.
The present invention adopts the method for the ball bearing that changes the outfit, make air pump axially do not need installation shaft to fixed component, simplified the structure of air pump.
The user that enforcement of the present invention can make the oil gas pump does part and changes and can obtain a no oil gas pump on original basis that the oil gas pump arranged, avoided the waste of fund and equipment.
