The life of a diesel dewatering 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. The first thing to be clear is that
the three types of filters for the engine driven water pump include the air
filter, the oil filter and the diesel filter. The service life of the diesel
pump unit should be extended. In the meantime, 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.
Trailer mounted pump can not be
installed, reverse-mounted or mis-assembled with various sealing gaskets and
rubber connecting pipes during installation, and ensure the tightness of the
embedded parts. The paper dust cup air filter is used for 50-100 hours per
work. To remove the dust once, use a soft brush to brush off the surface dust.
If the working time exceeds 500 hours or 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 water 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 diesel trash 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 diesel dewatering 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 by adding washing oil. Then, the diesel engine irrigation pump 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.
The three filters, air filter,
oil filter and fuel filter, are consumables and must be replaced when used for
more than 500 hours. In this way, the service life of the diesel water pump can
be better extended. The pump on the engine driven trash pump should prolong the
life, and the first is to avoid the empty pump. 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.
