    Abstract: A high volume high pressure common rail pump for a fuel system includes pairs of pump head assemblies in phase with each other but oriented in opposition to one another about a rotating cam shaft. Pump pistons in the pump head assemblies simultaneously undergo pumping strokes via a shared two lobe cam of the rotating cam shaft. The pump may include two pairs of pump head assemblies, and each head assembly may include two pump pistons. The cam shaft includes two cams sufficiently out of phase with one another that the cam shaft always has a positive torque even when the cam lobes are symmetrical. In addition, because the pumping is done simultaneously on opposite sides of the cam shaft, the forces on the cam shaft are balanced and its support bearings experience less wear and tear.

    Abstract translation: 用于燃料系统的高容量高压共轨泵包括相互相位但相对于旋转的凸轮轴彼此相对定向的成对的泵头组件。 泵头组件中的泵活塞同时通过旋转凸轮轴的共享的两个凸角凸轮进行泵送冲程。 泵可以包括两对泵头组件，并且每个头组件可以包括两个泵活塞。 凸轮轴包括彼此完全不相位的两个凸轮，即使当凸轮凸角对称时，凸轮轴总是具有正转矩。 另外，由于在凸轮轴的相对侧同时进行泵送，所以凸轮轴上的力是平衡的，并且其支撑轴承经历较少的磨损。

    Abstract: This invention provides a reciprocating pump system having means for determining the cylinder head pressure of at least one cylinder of each pump in the system. A control circuit continually determines the average cylinder head pressure, estimates the pump bearing life that has been consumed and the remaining pump bearing life from the pressure head information. The control circuit also controls the operation of the pumps as a function of cylinder head pressure. A temperature sensor coupled to the pump system provides temperature of the pump oil. The control circuit controls the operation of the pump as function of the pump oil temperature. The pump speed is decrease when the pump oil temperature exceeds a predetermined value. A vibration sensor coupled to the pump provides vibration level to the control circuit, which controls the pump operation in response thereto.

    Abstract: An apparatus is provided for monitoring a rotor mounted for rotation by bearings within a stationary housing of an apparatus, such as a sealless pump. In a first embodiment, the monitoring apparatus includes at least one magnet mounted on the circumference of the rotor and a plurality of hall effect devices which sense magnetic flux density as the rotor rotates to generate signals representative of radial and axial bearing wear as well as signals representative of the direction of rotation of the rotor. In a further embodiment, the monitoring apparatus includes magnetic material mounted in one or more locations around the rotor or entirely around the rotor and a plurality of hall effect devices and associated magnets mounted within the stationary housing and surrounding the rotor. The monitoring apparatus further includes a monitor for monitoring the amount of electrical power driving the pump as well as a monitor for monitoring the temperature of a containment shell which encloses the rotor within the sealless pump.

    Abstract: A pump shut-down system is disclosed for preventing damage to the pump from bearing failure. That system has a metal bar located within a preset clearance distance from a traveling element of the pump (such as a piston rod), a voltage source in electrical contact with the metal bar, an automatic shut-down relay in electrical contact with the voltage source, and an electrical ground on the pump in electrical contact with the voltage source. The metal bar, voltage source, automatic shut-down relay, and electrical ground all form an electrical circuit. That circuit is open when the metal bar is not in physical contact with the traveling element, and is closed whenever the metal bar is in physical contact with the traveling element. Whenever the circuit is closed, the automatic shut-down relay shuts down the pump.
