When the diesel trash pump
suddenly sheds water during use, it is not easy to reinstall. Open the outlet
pressure gauge and the inlet vacuum pump, and after opening the appropriate pressure,
slowly open the gate valve and check the load of the pump set.
Try to control the flow and
head of the trailer mounted pump, and use it within the range indicated on the
sign to ensure the energy saving effect of the diesel pump at the efficiency
point. During the operation of the pump, attention should be paid to changes in
flow and head at all times. The installation of the diesel engine pump is also
very particular. On the side with the dust cover, it is also necessary to
install it toward the side of the impeller. The grease is filled during
installation and must not be forgotten. After the diesel engine water pump has
been running for 24 hours, a grease gun is used to inject the grease into the
bearing.
It is not allowed to use a
gate valve on the input diesel engine irrigation pump to regulate the flow in
order to avoid cavitation. The pump should not be operated continuously below
the rated flow. If it is necessary to operate under this condition, a separate
water injector should be added and the flow rate should be above the above
value. Always check the loose ground of the diesel dewatering pump, whether the temperature of the pump casing is
consistent with the inlet temperature, and regularly check the vibration of the
pump. In the process of using the diesel water pump, there will be water
leakage. The specific reason is that there are many kinds. It can be divided
into two different situations, a large number of leaks are unlikely to occur,
and a small amount of leaks can be discharged through the leaking nozzle. It is
normal to have a small amount of leakage at the beginning of the run, so don't
be surprised.
When the conveying medium
is transferred to the heat of the pump cover and the bearing of the diesel
water pump, the surface of the pump cover and the bearing seat is dissipated,
so that the temperature of the bearing seat is matched with the temperature of
the shaft. Therefore, when selecting the installation position of the diesel
water pump, do not have any heat storage. When designing the flow rate of a
diesel engine pump, it is necessary to consider the specific use environment,
regardless of whether the flow rate is designed to be large or small. The
design of the diesel pump body and the construction of the impeller are
inseparable. There are many different forms in terms of the design of the
individual pump body.
Diesel pumps are flat, inflated,
spiral, and so on. The impellers of engine driven water pump have different distances of clearance, and there
are single-stage and multi-stage distinctions, which are closed and open. The
larger the gap, the faster the flow of water will pass. Of course, the premise
is that the horsepower of the engine must be matched to the selection of the
impeller. The use of diesel water pumps is very extensive and is used in many
places where water needs to be pumped, especially where it is necessary to
remove sewage.
