The power end lubrication system provides lubrication for the triplex pump crankshaft and the quintuplex pump crossheads. The power end lubrication system is driven by a hydraulic pump that is mounted on the auxiliary drive for the transmission. The power end lubrication system is active when the deck engine is operating. A
The fluid end lubrication system provides lubrication for the packing for the quintuplex pump. The lubrication system is an air-over-the-top-of-oil type. The system is driven by air pressure. The lubrication reservoir is an ASME coded carbon steel pressure vessel that is registered with the National Board. The lubrication reservoir has a
The lubrication system includes the following components:
- Solenoid valve
- Pressure regulator
- Flow divider valve
- Flow control valve
- Check valves
- Relief valve
- Liquid filled pressure gauge
- Polyurethane catch tank
The polyurethane catch tank has a drain valve on the bottom of the tank. The lube system is off when the driveline brake is on. The oil drain is located under the quintuplex pump pistons. Oil drains into a polyurethane catch tank that is located between the rear tires on the curb side of the trailer. The polyurethane catch tank should be drained regularly. For information on the proper lubricant to use, see this Operation and Maintenance Manual, "Plate Locations and Film Locations".
The SPF343 Trailer Mounted Pumper is equipped with a suction stabilizer to reduce pulsation in the fluid end and the discharge lines. The stabilizer is installed at the forward end of the suction piping. The stabilizer must be charged and maintained. The internal cartridge must be charged with nitrogen to
The hydraulic starter system consists of a hydraulic starting motor that is driven by a hydraulic pump. The hydraulic pump is driven by the power take-off for the transmission. A solenoid valve is used to direct oil to the hydraulic starting motor when the engine start switch is engaged.
The cooling systems on the SPF343 Trailer Mounted Pumper consist of the following cooling circuits:
- The transmission oil is cooled by a jacket water heat exchanger that is mounted on the right side of the engine. The torque converter pump for the transmission circulates the transmission oil.
- The quintuplex pump power end lubrication circuit is cooled by an air-to-oil heat exchanger that is mounted inside the horizontal radiator.
- The fuel for the deck engine is cooled by a heat exchanger that is mounted inside the horizontal radiator.
- An air-to-oil heat exchanger that is mounted inside the horizontal radiator cools the hydraulic fan drive circuit.
Air-to-Air Aftercooler (ATAAC) - The inlet air is cooled after the inlet air passes through the turbocharger. The inlet air is passed through an aftercooler (heat exchanger) that uses ambient air for cooling. The inlet air that has been cooled advances to the inlet manifold.
Electrical Controls and Gauge Panel
The Universal Remote Control Console (URCC) is used to control the pumping unit. The following functions can be controlled: deck engine, gear selection, throttle control, pump delivery rate, and emergency shutdown.
Store the URCC in the storage box that is located next to the packing lube tank. The legs of the console are stored in a compartment which is located near the fire extinguisher. Visual warning and visual indication lamps are provided for the vital system parameters. This console is portable up to a distance of
The control cable has connectors that plug into the URCC on one end. The other end plugs into the main junction box. The trailer has 24 V battery power for the control system. The batteries are the primary source of power for the control system until the deck engine is running. Once the deck engine is operating, the 75 amp alternator will supply the power for the URCC.
The gauge panel is located next to the main junction box. The gauge panel provides gauge readings of temperature and system pressure. Gauges for the deck transmission and the pump have integral electrical switches. The switches will indicate the temperature to the URCC. The switches will also indicate the pressure conditions to the URCC.
The main junction box is the junction point for the following components: tractor engine, deck engine, deck transmission, pump controls, and sensors.
