6.2
Shut-Down Procedure
During shut-down, follow proper operating and safety procedures for dealing with well control and well service
manifolds valves. This shut-down procedure does not apply to well control, but to the recommended shut-down
of the MSI Hybrid™ Well Service Pump after well control procedures have been followed.
1)
Shift the transmission into neutral, allowing the pump to coast to a stop.
2)
Shut off the plunger lubrication system.
3)
Shut off the centrifugal pump supplying the suction pressure to the MSI Hybrid™ Well Service
Pump.
4)
Close any valves necessary to isolate the pump from well service fluid in the circulation tank.
5)
Leave the prime mover running so that oil to the MSI Hybrid™ Well Service Pump will continue to
circulate and cool down any internal parts that were under heavy load prior to the shut-down.
6)
When oil temperature has stabilized, the lubrication oil pump can be shut-down.
7)
Flush out the fluid end of the pump with water to eliminate any solid or chemical residues left over
from the well service operation.
8)
If the pump will be moved to another well location or back to the well service yard, drain any water
from the lubrication oil reservoir after the oil has returned to ambient temperature.
9)
If the pump is to be idle for more than a day, follow the fluid end preservation procedure in
Section
