The correction of the automatic shaft and bushing of the gear pump is corrected because of the self-component of the gear pump and the radial thrust generated when the forced gear is engaged; the shaft and the bushing hole are simply eccentrically grounded; the clearance is increased. Therefore, the oil is in operation. It will leak due to the increase of the gap; the oil supply is reduced. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
After the automatic shaft and bushing are worn, the shaft can be repaired by the neck or the bushing method. When the journal wear is fine; only the old bushing is pressed out and replaced with a new bushing; the shaft can usually be repaired; The gap can be recovered within the agreed range. The shaft and bushings are worn very badly; when the co-space is added a lot; not only the bushing is replaced; the shaft is also chromed or oscillating to increase the diameter; then grinding To the normative scale; to cooperate with the needs of rehabilitation journals and bushings.
After the inner cavity and gear teeth of the gear pump casing are worn out, the inner cavity and gear teeth of the pump casing are worn out; the pump oil quantity is greatly affected. When the shaft and the bushing or the shaft hole are severely worn; the tooth top and the pump casing are in operation. The inner cavity surface may have a touch that should not be present. And because the oil outlet cavity is higher than the pressure in the oil inlet cavity; under the effect of the pressure difference; the tooth tip and the oil inlet cavity of the pump casing are more touching; therefore, the inner cavity of the pump casing is There is more wear here; the gap between the inner cavity and the tooth tip is increased. Therefore, the pressure difference between the oil inlet and the oil discharge chamber is reduced; the scraping oil and the oil pressure effect are reduced; the oil supply pressure is reduced; the pump oil is formed. The amount of reduction. The wear of the inner cavity of the pump casing is usually corrected by the cavity setting method.
Secondly; because the teeth are worn in the direction of the tooth thickness; the meshing gap of the main and forced gears is increased. The wear characteristic is that the one-side wear is heavier; therefore, the gear can be turned over 180 degrees.
There is a certain gap between the gear end face of the gear pump and the correcting gear end face after the pump cover is worn and the inner surface of the pump cover; the end face clearance. The wear of the gear end face in the operation and the touch surface of the inner surface of the pump cover will cause the end face clearance. Increase; when the limit is exceeded; there will be a significant effect on the amount of pump oil.
When the gear end face is worn; the end surface can be flattened; the gear oil pump housing differentiation surface is re-ground together; to ensure that the pump end face clearance is within the required range.
