Definitions

  • This invention relates to pumps of the multiplex type. More particularly, but not by way of limitation, this invention relates to a triplex pump of the type in which the pump fluid is precompressed prior to discharge.
  • the present invention contemplates an improved hydraulically powered pump employing an improved control system whichconstantly monitors the operation of the pump during each phase of the pumping cycle to immediately correct any variations from optimum operating conditions.
  • An object of the invention is to provide an improved triplex pump having a precompression function.
  • FIG. 1 is a side elevational view partially broken away of a triplex pump according to the present invention.
  • each cam actuator 58 is operable, in connection with a precompression and stroke control valve or back position valve BP, to provide a signal that its associated piston rod assembly 42 has reached its back position.
  • the precompression and stroke control valves BP are also mounted on the pump 20 at that back position on a transverse valve mounting bar, indicated at 60.
  • the common conduit 61 connecting rod ends of the power cylinders 40 is in fluid circuit with a conventional accumulator 62 and with a source of power fluid through a normally closed fill valve, FV.
  • the conduit 61 and the rod ends of the power cylinders 40 are also in fluid circuit with a power fluid reservoir, remote from the pump 20, through a normally closed dump valve DV.
  • a rod end relief valve 64 provides selective communication between the rod ends of the power cylinders 40 and the remote power fluid reservoir in the event the power fluid pressure at the rod ends of the power cylinders exceeds a predetermined pressure.
  • control valve assemblies CV, the precompression valves PR, the fill valve FV and the dump valve DV which direct the power fluid, preferably water, are, in the illustrated embodiment, monitored by a separate control fluid circuit.
  • the control fluid circuit preferably utilizes a different fluid such as oil, air or a combination thereof. It will, however, be apparent that controls other than a control fluid circuit (e.g., an electrical sensing arrangement) may be utilized to monitor the power circuit. In the illustrated embodiment it will be assumed that oil will be employed as the control fluid.
  • a tandem wheel semi-trailer 66 provides the common frame for supporting these elements.
  • the mounting on the semi-trailer 66 is designed to permit the fluid end cylinders 24, the spacer frame assembly 51, and the power end cylinders 40 to move longitudinally relative to the semi-trailer for a limited distance, during reciprocation of the piston rod assemblies 42, so as to relieve any stresses on those members.
  • each control valve assembly includes a housing 90 having a longitudinal bore 92 extending therethrough.
  • An inlet bore 94 and an exhaust bore 95 are formed in the housing 90 and communicate between the longitudinal bore 92 and the upper surface 96 of the housing 90.
  • Counterbores 97 and 98 are formed respectively in the bores 94 and 95 forming respective annular shoulders 100 and 102 therein.
  • Annular inlet and exhaust chambers 104 and 106 are formed respectively in the counterbores 97 and 98.
  • a precompression passageway 107 is formed in the housing 90 and communicates between the inlet bore 94 and the front side 108 of the housing 90.
  • a cylindrically shaped inlet seat mount 114 is positioned within the counterbore 97 abutting the annular shoulder 100.
  • a substantially identical exhaust seat mount 116 is positioned within the counterbore 98 abutting the annular shoulder 102.
  • a substantially cylindrically shaped slotted inlet spacer 118 is positioned within the counterbore 97 abutting the upper end face of the inlet seat mount 114.
  • An annular inlet valve seat 120 is securely mounted between the inlet seat mount 114 and the slotted inlet spacer 118.
  • a substantially cylindrical slotted exhaust spacer 122 is positioned within the counterbore 98 and abuts the upper surface of the exhaust seat mount 116.
  • An annular exhaust valve seat 124 is secured between the slotted exhaust spacer 122 and the exhuast seat mount 116.
  • Each of the identical inlet and exhaust cylinder assemblies 126 and 128 includes a lower bearing and seal member 138 extending into the respective counterbores 97 and 98, a cylinder 140 extending upwardly from the lower bearing and seal member 138, an upper bearing and seal member 142 extending upwardly from the cylinder 140 and a cover 144 extending upwardly from the upper bearing and seal member 142 and capping the respective inlet and exhaust cylinder assemblies 126 and 128.
  • the elements of the inlet and exhaust assemblies 126 and 128 are secured together by means of suitable annular V retainer couplings 146.
  • These flanges 160 function as pistons and define, together with an upper and lower cylindrical surfaces 152 and 154 of the valve members I and E and the upper and lower bearing and seal members 142 and 138 and their annular seals 156 and 158 located at opposite ends of each of the cylinders 140, upper and lower control fluid chambers A and B.
  • Pressurization of the upper control ports l-A and E-A causes control fluid to enter the upper control chambers A of the inlet cylinder assembly 126 and the exhaust cylinder assembly 128.
  • the valve members 1 and E are thus caused to move to their lower or closed positions, as illustrated by the valve member E in FIG. 5.
  • pressurization of the lower control ports [-8 and E-B moves the valve members I and E to their upper or open positions, as indicated by the valve member l in FIG. 5, the actuation of control fluid in the lower chamber B upon the pistons 160.
