摘要： A syringe pump for aspirating and dispensing fluids is provided. The syringe pump includes a pump casing having an inlet port and an outlet port, a ceramic piston liner received within the pump casing and a ceramic piston. The liner has an internal bore formed by a cylindrical wall, wherein the cylindrical wall further defines a fluid path between the inlet port and the outlet port of the pump casing. The piston is axially movable within the bore of the piston to urge a flow of fluid between said inlet port and said outlet port via said fluid path.

摘要： An electronic angle adjustment mechanism for a pump and a motor generally includes a base and an actuating motor. The base has an upper portion mounted to a motor, a lower portion mounted to a pump, and a hinge for pivotably moving the upper base portion in relation to the lower base portion. The actuating motor is mounted on an attachment plate that is attached to the upper base portion. The actuating motor is connected to a worm screw that engages an arcuate member attached to the lower portion to pivot about the hinge and change the angle between the upper and lower base portions.

摘要： A lockout system for a metering pump is provided. The lockout system can include a user interface that is used to switch the pump between a locked configuration and an unlocked configuration. In the locked configuration, the operation of the pump cannot be adjusted through the user interface. In the unlocked configuration, the operation of the pump can be adjusted through the user interface. The lockout system can include a passkey notice that provides information regarding how to use the user interface to switch the pump between the locked and unlocked configurations.

摘要： A miniature transportation device is disclosed and includes a gas inlet plate, a resonance plate and a piezoelectric actuator, which are stacked on each other sequentially. The gas inlet plate comprises at least one inlet, at least one convergence channel and a convergence chamber. The convergence channel is in fluid communication with the inlet and the convergence channel. The resonance plate comprises a central aperture. A chamber gap is formed between the resonance plate and the piezoelectric actuator to define a first chamber. When the piezoelectric actuator is enabled, the gas is fed into the miniature gas transportation device through the inlet of the gas inlet plate, converged to the convergence chamber through the convergence channel, transferred through the central aperture of the resonance plate, introduced into the first chamber, and transferred along a transportation direction through a vacant space of the piezoelectric actuator to be discharged continuously.

摘要： A viscous fluid is dispensed precisely using a fluid pump, control valves configured to control both the air inlet and outlet of the fluid pump, an optional adjustable regulator further controlling the air outlet, and a control circuit that opens and closes the control valves. To further increase the precision, additional control valves can be used to control liquid inlet and outlet of the fluid pump.

摘要： A system comprises a variable displacement pump, a metering valve, a bypass line, a pressure regulating valve, a position sensor, and a control system. At least one fuel nozzle can be in fluid communication with the output line downstream of the metering valve, wherein the variable displacement pump is configured to supply fuel to the at least one fuel nozzle. The metering valve can be disposed in the output line for controlling outlet flow from the variable displacement pump. The system can also include an actuator line parallel to the variable displacement pump and connected to the output line to provide actuation pressure from pump output of the variable displacement pump.
