The
life of a self priming trash pump unit depends on how it is used properly. If
it is used in accordance with the skill of use, it will directly increase its
life time. below
First
of all, it is clear that the diesel fuel pump unit's consumables include air
filter, oil filter and diesel filter. It is necessary to extend the service
life of the diesel pump unit during use. It is necessary to strengthen the
maintenance of the three filters of the air filter, the oil filter and the
diesel filter to fully exert their functions. The air filter should not be
installed, reverse-mounted or misplaced with each sealing gasket and rubber
connecting pipe during installation, and ensure the tightness of each pressing.
Use the paper dust cup air filter. For every 50-100 hours of work, remove the
dust once. Use a soft brush to brush off the surface dust. If the working time
exceeds 500 hours or it is damaged, it should be replaced in time. Use oil bath
air filter, clean the filter element and replace the oil in every 100-200 hours
of operation. If the filter element is broken, it needs to be replaced
immediately, and pay attention to the addition of oil according to the
regulations.
If
the oil filter is not in time for maintenance in the engine driven trash pump,
the filter element is clogged, the oil pressure is increased, the safety valve
is opened, and the lubricating oil directly flows into the main oil passage,
which will aggravate the wear of the lubricating surface and affect the service
life of the wet prime pump. Therefore, the oil filter should be cleaned once
every 180-200 hours of operation and found to be damaged. It should be replaced
immediately to prevent impurities from entering the lubrication surface. The self
priming sewage pump should be used in seasons. The crankcase and each
lubricating surface should also be cleaned. The method is to mix the oil,
kerosene and diesel oil for washing oil. After the oil is released, it can be
washed with detergent oil. Then, the diesel pump unit runs at low speed for 3-5
minutes. , then drain the washing oil and add new oil.
For
each fuel filter in the fuel supply system, every 100-200 hours of operation,
the debris should be removed once, and the fuel tank and each oil pipeline
should be thoroughly cleaned. When cleaning the filter element and seal, it should
be especially careful to find damage and need to be replaced in time. During
the seasonal transition, the parts of the entire fuel supply system should be
cleaned. The diesel used should meet the seasonal requirements and require 48
hours of precipitation purification.
Note:
The three filters of air cleaner, oil filter and fuel filter are consumables.
When used for more than 500 hours, they must be replaced with new ones. In this
way, the service life of the diesel pump unit can be better extended. The pump
on the 6 inch trash pump should extend the life, and the first is to avoid
empty pumps. The second operation is to avoid rust and corrosion of the
impeller and the seal ring, and damage the seal gap. Third, it is necessary to
avoid the horizontal centrifugal pump pumping more than the suction stroke. Do
not put the fourth packing too tight, and have enough cooling water to flow out
of the shaft.
