Enhanced fluid filtration methods, systems, and techniques are disclosed that can leverage the function of a supplemental pump in combination with the existing components of a machine, such as the main pump of an electrically-powered machine with an engine. In various embodiments, a supplemental filter apparatus may be operatively associated with the supplemental pump to provide filtration of fluid flowing through the machine. A control module may be operatively associated with the supplemental pump and/or various components of the machine. The control module may be programmed to activate or deactivate the supplemental pump, a valve, or take other actions in association with detecting the existence of one or more filter triggering conditions.

A multiphase flow mixed delivery device employing reciprocating driving performed by a liquid in two chambers comprises a left container (1), a right container (2), a power pump (3), a data acquisition and control system (4), a solenoid valve group, a check valve group, an inlet manifold (5), and an outlet manifold (6). A vacuum suction chamber and a compression discharging chamber alternately formed by the two containers serve as a suction chamber and a discharging chamber of a multiphase mixed flow delivery pump. After gas in a liquid-gas mixture is separated in the container, the gas is compressed by a liquid, and is discharged out of the container. The power pump constantly operates in a pure liquid working condition, thereby eliminating the issue in which a liquid with a high gas content affects the power pump. The invention requires only an ordinary water pump to achieve mixed delivery of a multiphase flow, and the ordinary water pump can even serve as a vacuum pump and a compressor for pure gas and operate continuously. Also disclosed is a multiphase flow mixed delivery method using the multiphase flow mixed delivery device employing reciprocating driving performed by a liquid in two chambers.

In one embodiment, a pipeline system includes a pipe fitting to be secured to a pipe segment including tubing that defines a pipe bore and a fluid conduit implemented in a tubing annulus of the tubing, in which the pipe fitting includes a fitting grab notch implemented on an outer surface of the pipe fitting, and a supplemental containment wall assembly to be deployed at the pipe fitting. The supplemental containment wall assembly includes a containment wall shell to be secured circumferentially around the pipe fitting to define a fitting annulus that is sealed at least between the outer surface of the pipe fitting and an inner surface of the containment wall shell to facilitate providing multi-wall containment in the pipeline system and a shell grab tab implemented on the inner surface of the containment wall shell, in which the shell grab tab matingly interlocks with the fitting grab notch on the outer surface of the pipe fitting to facilitate securing the containment wall shell to the pipe fitting.
