Usually pump regular maintenance to avoid small defects into a big flaw, an important measure of the small problems beco me big problems,
is to create conditions in order to extend the unit life, improve the equipment in good condition, energy conservation. Regular
maintenance is divided into localized maintenance, overhauls and expand sexual overhaul three. Pump products of Shanghai the Hutai Valve
Manufacturing Co., Ltd. covers: chemical pumps, fire pumps, diaphragm pumps, sewage pumps.
First, the localized maintenance
The general arrangements for running clearance or winter maintenance of a planned manner. Local maintenance of the project.
1) adjust the pump to adjust the Copper Sleeve with oil check processing.
2) centrifugal pump guide bearing inspection. Rubber bearing wear, leakage volume, journal wear To check, record, process. The
majority of the oil guide bearing Pap alloy steel bearing, soft and easy to wear, such as poor sealing effect, stop the oil basin water,
sediment precipitation, run-time wear of bearings, journal. Especially not spraying or set package of stainless steel, carbon steel
crankshaft, and to understand their corrosion, wear, should be regularly checked.
3) thermometer, meter, relay protection devices, inspection, testing.
4) the upper and lower guide bearing tank spaces and turbine oil sample for testing.
5) bearing clearance and check the tile surface. According to the temperature of the thermometer in the run-time, with the
purpose to check the bearing clearance and axial plane.
6) the braking part of the check processing.
7) unit fasteners, such as anchor bolts, shaft key, the positioning pin is loose.
8) oil cooler visual inspection and by the water test to see whether the leakage.
9) check the impeller blades and impeller shell and sediment of the cavitation wear, and measured to record its extent.
10) measuring the clearance of the blade and impeller casing.
Second, the unit overhaul
A planned overhaul of the recovery unit.
Damage to the unit first, accident damage, the probability of occurrence is very small. Normal damage, friction and wear, such
as running, cavitation damage, sediment abrasion, the probability of occurrence is very small. Normal damage, friction and wear, such as
running, cavitation damage, sediment abrasion, all kinds of interference caused by vibration, exchange the role of stress and corrosion,
electrical insulation aging.
Third, expanding sexual overhaul
When the pumping station due to the basis of uneven subsidence caused by the unit axis offset, change vertical concentricity; or
parts of serious wear and tear, damage, leading to a serious decline in unit performance and the technical and economic indicators to be
the disintegration of the whole, repeat the repair, replacement , adjusting and part of the transformation.
