学做肉丸子HT -400™ Pump
The Industry Standard
H alliburton’s HT-400™ Pump is a lightweight,rugged,
versatile unit that was introduced in 1957.Its name denotes Horizontal Triplex and its original rating of 400 horpower.Since its debut,the basic design has been improved and upgraded until it now is rated at 800 hp maximum in some configurations.The pump has performed millions of operating hours in fracturing,acidizing,cementing,and sand and water control work.
Features
The Halliburton twin-pump or flexibility concept is particularly uful when preci pumping ranges and
controls are required.Halliburton exclusively manufactured the HT-400 pump power end,so that practic
ally all parts are interchangeable.The exception is that the power end ca is built in both left- and right-hand configurations.Internal parts,including the proven worm/ring gear ts,are identical,only the ca is different.
Power ends can be fitted with any of the five sizes of fluid ends – 3 3/8”,4”,4 ½”,5”and 6”plungers – each with characteristics suitable for specific applications.Power end components:
•Ca and Drive Gears:Power End cas are
manufactured exclusively by Halliburton in both left- and right-hand models.They are made of high-strength weldments of Halliburton design.They are not interchangeable.•Crankshaft:Heat-treated steel forgings are ud to manufacture crankshafts.All cranks are the same,even for left- and right-hand units.•Connecting Rods:Connecting rods are made from aluminum forgings.The identical rods are internally drilled to provide lubrication to the crosshead pins.•Crossheads:Crosshead bodies are made of heat-treated steel alloy castings.They are fitted with replaceable,high-leaded bronze shoes on both top and bottom.•Lubrication:Standard lf-contained power end
lubrication system is pressurized by an internal crescent gear-type pump driven off the end of the worm gear.Positive pressure lubrication is supplied to the crosshead slides,gear support bearings,cr
ankshaft throws and crosshead pins.•Cooling:Tube-and-shell coolers are optional add-on components,which provide remote cooling capacity.The HT-400 pump can be fitted with radiator-type,air-to-oil or water-to-oil cooling systems as well.
Spacers are special components designed to parate the fluid end from the power end of the HT-400 pump.The interchangeable spacer insures that fluids being pumped do not contaminate the power end and cau premature failures.Each fluid end package is manufactured from three parate chambers – all identical and completely interchangeable.If one chamber of a fluid end should cau trouble,it can be changed quickly and the pump returned to duty.Fluid End components:
•Chambers:The fluid end is constructed from three
parate but identical forged and heat-treated chambers.Fluid ends can be supplied in any of five plunger sizes and each size can be fitted to the standard power end without alteration of either fluid or power end.•Valves and valve ats:Fluid ends are fitted with
replaceable,carburized valves and ats of Halliburton design and manufacture.Most of the valve asmbly parts are interchangeable between suction and discharge ports within a given size and so
me are even interchangeable between sizes.•Lubrication:A parate lubrication system supplies lubricant to the fluid end package.

Testing
速读法Each HT-400 pump undergoes rigorous testing before it is placed in rvice.Fluid end chambers are tested individually to pressures far beyond the anticipated operating pressures and then tested again when they are asmbled into three-chamber fluid ends.A third test is performed after the fluid end is attached to the power end asmbly.Power ends are submitted to equally rigorous
花奶testing in a Halliburton test facility.Pumps are run for over an hour at various speeds and at various pumping pressures before they are installed on a unit.After the unit is completed,each pump is further tested during the unit checkout.
