Definitions

  • the present invention relates to a flange mounted drain and/or vent tube associated with the inlet to or the outlet from a fluid pumping device and to a method of attaching the flange mounted drain and/or vent tube to the casing of the fluid pumping device which provides simplification in the manufacturing process while substantially reducing the costs of manufacture, testing, inspection, and maintenance of the fluid pumping device.
  • Fluid pumping devices utilized in petroleum and chemical applications require the use of a multi-part drain and/or vent tube assembly operatively connected to the inlet to and/or outlet from of the fluid pumping device.
  • the attachment of a drain and/or vent tube to a fluid pumping device used in petroleum and chemical applications is currently and has been done in the past by employing a series of weldments to operatively secure and connect the multi-part drain and/or vent tube assembly to the inlet or outlet of the cast fluid pumping device. Because such fluid pumping devices are used in petroleum and chemical applications, the American Petroleum Institute (API) has issued and requires stringent testing, inspection, and maintenance of each weldment.
  • API American Petroleum Institute
  • the present invention is disclosed to solve the aforementioned problems associated with the assembly of drain and/or venting of fluid assist or pumping devices.
  • the significant disadvantages of the prior art pumping devices are overcome by eliminating the process of utilizing weldments in securing a multi-part drain and/or vent tube to the inlet or outlet of the pumping device.
  • the process of the present invention is accomplished by drilling or fabricating a tubular drain/vent conduit within the cast fluid housing to communicate between the inlet or outlet of the pumping device and the outer surface of the cast fluid housing.
  • the outer surface of the cast fluid housing, surrounding the outer tubular opening of the tubular drain/vent conduit is substantially vertical to permit the mounting of a flanged drain and/or vent adaptor member to the cast fluid housing coaxially with the tubular drain/vent member conduit.
  • the outer surface facing of the cast fluid housing, surrounding the tubular opening of the drain/vent is substantially planar to permit the mounting of the flanged adapter member to the cast fluid housing.
  • the flange adapter member is secured to the cast fluid housing utilizing a plurality of bolt members engaging threaded openings in the fluid housing.
  • the flanged adapter member includes a bore extending therethrough and a machined projection portion structurally arranged to sealingly engage a recessed shoulder portion surrounding the opening to the tubular drain/vent member in the cast fluid housing. Additionally, the projecting cast fluid housing surrounding the opening to the drilled tubular drain/vent member includes a recessed shoulder portion which is designed to recess the machined projection portion of the flange adapter member when the flange member is mounted to the fluid housing to provide a seal therebetween.
  • FIG. 1 is a perspective view of a drain and/or vent assembly connection to a cast fluid housing of a prior art petroleum and chemical pumping device;
  • FIG. 2 is a cross-sectional view taken through the cast fluid housing taken along line 2 - 2 through the drain and/or vent assembly connection in FIG. 1 ;
  • FIG. 3 is a perspective view of the attachment of a machined flange adapter member to the drain and/or vent conduit within the suction base of a petroleum and chemical pumping device in accordance with the present invention
  • FIG. 4 is a cross-sectional view taken along line 4 - 4 in FIG. 3 ;
  • FIG. 5 is a perspective view of the machined flange adapter member in accordance with the present invention.
  • FIG. 6 is an enlarged view of FIG. 4 illustrating the engagement and attachment of the machined flange adapter member to the cast fluid housing of a pumping device to axially engage and seal the drain/vent tube member in accordance with the present invention.
  • FIGS. 1 and 2 there is illustrated in FIGS. 1 and 2 the attachment of a multi-part drain and/or vent tube assembly 12 to the inlet or outlet 13 of a fluid pumping device 10 having a cast fluid housing 11 , mounted on housing supports 11 b , in accordance with the prior art. As shown in FIG.
  • the prior art drain/vent tube assembly 12 is comprised of several parts including an engaging portion 12 a , an elbow portion 12 b , and an elongated portion 12 c extending through an opening 14 in the cast fluid housing sidewall 15
  • the several parts of the drain/vent tube assembly 12 are connected and secured together by weldments 16 , which include weldment 16 a which integrally secures engaging portion 12 a of the multi-part tube assembly 12 to the inlet or outlet 13 of the cast fluid housing 11 , weldment 16 b which integrally secures the elbow portion 12 b of the tube assembly 12 to the engaging portion 12 a of the assembly, and weldment 16 c which integrally secures the elongated portion 12 c of the tube assembly 12 to the elbow portion 12 b of the assembly.
  • drain/vent tube assemblies 12 it is the practice of the prior art drain/vent tube assemblies 12 to extend the elongated portion 12 c of the drain/vent tube member or assembly 12 outwardly through an opening 14 in the cast fluid housing 11 of the pumping device 10 .
  • weldments 16 d are required to secure a support gusset 14 a for the drain/vent tube member 12 extending through the opening 14 in cast fluid housing 11 to prevent fracture of the drain/vent tube assembly from the pumping device.
  • the fluid pumping device 10 is designed for usage in petroleum and chemical pumping applications. Accordingly, the American Petroleum Institute (API) has mandated stringent testing and inspections of each weldment associated with the fluid pumping device by requiring radiography and liquid penetrant examinations of each weldment. However, such tests and examinations are costly and very time consuming. Thus, by reducing the number of weldments and thereby eliminating the difficulties and accessibility to the various weldments associated with the pumping device, substantial savings of labor and labor costs involved in such tests and examinations result in substantial cost savings in the manufacture and maintenance of the fluid pumping devices of the present invention.
  • API American Petroleum Institute
  • the fluid pumping device in accordance with the present invention, has a longer operating life because of the fluid pumping device's resistance to breakage and leakage. It has been determined that the labor and costs saved by the present invention in eliminating the need for weldments can result in a 7-10 percent cost advantage savings for fluid pumping devices made in accordance with the present invention.
  • the present invention contemplates and discloses a simplified assembly and structure for communicating a drain/vent tube member 12 with the inlet or outlet 13 of a fluid pumping device 10 .
