As the working time of any machine continues to lengthen, the skills of gear pump will continue to decline, eventually leading to various problems. Among them, the two most common faults are insufficient pump oil and no pump oil of gear pump. There are many reasons for these two faults, which can be basically classified as component wear, including the wear of driving shaft and bushing, the wear of central hole and shaft pin of driven gear, Caith an cuas istigh de thithíocht caidéil agus fearas, agus an t -aghaidh agus an clúdach caidéil a chaitheamh ag deireadh giaranna . Nuair a dhéanaimid an caidéal giair a dheisiú, ba cheart dúinn a bheith ar an eolas faoi conas damáiste do gach cuid
{1. Caith seafta tiomána agus bushing:
When the driving shaft and bushing of the gear pump are worn, the matching clearance will increase, which will inevitably affect the oil volume of the pump. In this case, the normal fit clearance can be restored by repairing the driving shaft or bushing. If the driving shaft is slightly worn, just press out the old bushing and replace it with a standard bushing, and the fit clearance can be restored to the allowable range. If the driving shaft and bushing are seriously worn and the fit clearance exceeds the standard, not only the bushing shall be replaced, but also the diameter of the driving shaft shall be increased by chromium plating or vibration surfacing, and then ground to the standard size to restore the fit requirements with the bushing.
{2. Deisiúchán ar chaidéal ola bealaithe deisiú sliogáin de chrack bhlaosc:
Is féidir scoilteanna bhlaosc a dheisiú le slat táthú copair nicil 508 . Caithfidh an táthú a bheith daingean agus saor ó phoill aeir, agus ní bheidh an earráid cothrom den dromchla comhpháirteach leis an gclúdach caidéil níos mó ná 0 . 05mm.
{3. Deisiúchán ar chlúdach caidéil:
Deisiúchán an eitleáin oibre: Má chaitear plána oibre an chlúdaigh caidéil beagán, is féidir an rian a chaitheamh a dhíchur trí mheilt láimhe, is é sin, cuir gaineamh beag comhla ar an ardán nó pláta gloine tiubh, agus ansin cuir an clúdach caidéil air le haghaidh meilt go dtí go bhfuil an t -eolas caidéil ag caitheamh an chaidéil oibre agus go bhfuil an t -éadach caidéil ag caitheamh an chaidéil ar an bpumpáil ar an bpumpáil ar an bpumpáil ar an gcaidéal ar an gcaidéal agus go bhfuil an caidéil ag caitheamh an chaidéil ar an bpumpáil ar an gcaidéal agus nuair a bhíonn an t -éadain ag an bpumpáil ar an gcaidéal agus nuair a chaitheann an caidéil oibre an caidéil agus má tá an caidéil á chaitheamh ag an bpumpáil ar dhromchla na caidéil. 0 . 1mm, déanfar é a dheisiú trí chasadh ar dtús agus ansin meilt.
{4. giaranna a chur ar ceal:
The gear wear of gear pump is mainly at the tooth thickness, while the wear of gear end face and tooth top is relatively light. The gear is worn on one side at the tooth thickness, so the gear can be turned 180 degrees for use. When the gear end face is worn, the end face can be ground flat, and the joint surface of the lubricating oil pump housing can be ground at the same time to ensure that the Tá an t -imréiteach idir an aghaidh giaranna agus an clúdach caidéil laistigh den raon caighdeánach .
