摘要： An earth boring bit has a bit body with at least one bearing pin. A cone is rotatably mounted on the bearing pin. A seal assembly is located between the cone and the bearing pin, the seal assembly having at least one flexible seal member. A flexible pressure compensating diaphragm is mounted in the body. The diaphragm has one side adapted to be exposed to borehole fluids and another side in contact with lubricant contained in bearing spaces between the cone and the bearing pin. The flexible seal member and the diaphragm are formed of a fluorinated elastomer. The elastomer is either a perfluoroelastomer (FFKM) or a fluoroelastomer (FKM).

摘要： A drill bit for drilling a wellbore, the drill bit having a body and at least one bearing. A rotary cone is rotatably attached to the bit body at the bearing. A lubricant reservoir is located in an inner portion of the bit body and is in fluid communication with the bearing. A communication port leads from the inner portion of the bit body to the exterior of the bit body. A fiber reinforced elastomeric pressure compensator diaphragm separates lubricant in the lubricant reservoir from the communication port.

摘要： A metal face seal for an earth boring drill bit where the drill bit has a bit body, at least one bit leg, a bearing pin on each bit leg, and a cone rotatably mounted on each bearing pin. The metal face seal is located in the cavity formed between the interior surface of the cone and the bearing pin. The metal face seal consists of a rigid seal ring having a forward surface that engages a rotating seal surface of the cone. An energizer ring biases the rigid seal ring toward the rotating seal surface. A secondary seal engages the bearing pin surface, the energizer ring, and the rigid seal ring. The secondary seal ring has a protuberance on its forward side for filling void spaces between the energizer ring, the rigid seal ring, and the secondary seal ring.

摘要： An assembly controls the liquid level in a vessel in which a submersible pump is disposed. The assembly has a switch housing and a float housing, arranged proximate to each other. A switch in the switch housing selectively energizes a motor associated with the pump. When a float disposed in the float housing moves in response to a change in the liquid level of the vessel, the movement is coupled to the switch by a pair of magnets arranged in attractive relationship to each other. One of the magnets is in the switch housing and the other is in the float housing. The magnets interact by providing force fields that acts through a wall that separates the switch housing and the float housing. A lever on which the switch housing magnet is positioned tilts the magnets away from alignment as they approach each other, reducing the increase in attractive force therebetween.

摘要： A method of non-destructively identifying and characterizing defects in a rotary drill component is provided. The method includes providing a drill component and an ultrasonic test system including a phased array ultrasonic transducer (PAUT). The method also includes acoustically coupling the PAUT to a surface location, transmitting focused ultrasonic acoustic waves at the location into the PAUT and recording a reflected acoustic response corresponding to a portion of a predetermined volume of a microstructure of the component associated with the location on the surface. The method also includes storing the response and moving one of the transducer or the component to a plurality of unique locations representative of the predetermined microstructure and repeating these steps. The method also includes processing the responses and providing an output signal to an output device configured to provide an output indicative of differences in the output signal within the predetermined volume of the microstructure.

摘要： An earth boring bit has thrust faces with one of the thrust faces being at least partially tilted relative to the other. The bit has a cone rotatably mounted to a bearing pin of the bit body. The thrust faces are in the cone and on an end of the bearing pin. One of the thrust faces is completely flat and perpendicular to the axis of the bearing pin. The other thrust face has a tilted portion that is at a skewed angle relative to the axis. The tilted portion creates converging and diverging zones between the thrust faces.

摘要： An earth boring bit has rotating cones with two lubricant passages to increase bearing capacity and cause lubricant circulation. A lubricant reservoir in the body supplies lubricant to passages between the cone and bearing pin. A pressure compensator equalizes lubricant pressure to the exterior of the bit. A first passage leads from the reservoir to the upper side of the bearing pin. A second passage leads from the reservoir to the bearing pin at a point from 185 degrees to 225 degrees as seen from an inner end of the bearing pin. This point is located in a diverging region 51d of an annular clearance surrounding the bearing pin.
