摘要： A reciprocating piston pump may include a pump chamber, a piston seal, a monolithic partially fluorinated polymer piston with a fluid engaging end, a seating end, and a longitudinal outer piston surface extending between the fluid engaging end and the seating end. The reciprocating piston pump may further include a drive assembly coupled to the seating end of the monolithic partially fluorinated polymer piston. The drive assembly operates to reciprocate the monolithic partially fluorinated polymer piston within the pump chamber between full aspirate and full dispense positions. The piston seal forms an interface between the longitudinal outer piston surface of the piston and the pump chamber. The monolithic partially fluorinated polymer piston and the drive assembly are configured such that the piston seal interfaces with the longitudinal outer piston surface over a full stroke length of the drive assembly between the full aspirate and full dispense positions.

摘要： Various assemblies that can be used in a mud pump with a plunger-style piston to reduce seal failures, to offer control in variability of the circumference of the piston to thereby control fluid pressure, and to provide visibility into seal condition during operation. In one embodiment, a sleeve that can vary the overall effective circumference of the piston enables fluid pressure control. In some embodiments, seal failure within a pump can be monitored via a drain port that would receive drilling fluid leaking past a seal during operation of the pump. A discharge valve can be provided between an inlet and an outlet of the mud pump to reduce the load on pump components during start-up. Additional systems, devices, and methods are also disclosed.

摘要： A high-pressure fluid pump is operable to pressurize a fluid and includes a hollow stud including a first end, a second end, and a cylindrical space extending between the first end and the second end and a housing fixedly coupled to the first end of the hollow stud. A high pressure cylinder is disposed within the cylindrical space of the hollow stud. The high pressure cylinder includes a bore that extends from a first end to a second end of the high pressure cylinder. A seal head is engaged with the first end of the high pressure cylinder to define a seal therebetween and an end cap is coupled to the second end of the hollow stud and the seal head. The end cap is operable to apply a compressive force to the seal head to compress the seal head against the cylinder and to apply a tensile load to the hollow stud. A plunger is movable within the bore to pressurize the fluid in a space defined by the piston, the seal head, and the high pressure cylinder.
