A coating apparatus for coating a perimeter surface of a pipeline. A frame selectively mounts a sprayer on the pipeline. The sprayer can spray fluid along a flow path in a spraying mode and preparation mode. In the preparation mode, a fluid diverter moves into the flow path to divert the fluid delivered from the sprayer away from the pipeline. In the spraying mode, the fluid diverter moves out of the flow path to permit the sprayer to coat the perimeter surface of the pipeline with a curable liquid. A vacuum system can draw a vacuum through the diverter to remove the fluid the sprayer sprays in the preparation mode. The flow path can be located in a spray shroud. The diverter can fluidly couple the vacuum system to the shroud interior in the spraying mode to remove overspray.

A paint spraying machine for applying plural component coating materials with a component A and a component B, the machine having separate hoppers for each component in which the components A and B are held respectively, a pump operable to separately pressurize the components to independently selected pressures for each component, where the pump includes a separate pump lower for each component, a mix manifold configured to receive the components separately from the pump and mix the components to a selected, fixed mix ratio, manually operated controls adjustable to control flow of the components through the machine, and a spray line including a spray gun operable to spray the mixed and pressurized components. The fixed mix ratio is determined by the volumetric displacement of the pump lowers selected. The components remain separate until combined together in the mix manifold forming the coating.

A fluid delivery system includes a conduit. The conduit is configured to deliver a fluid. The conduit further includes a first electrically conductive element configured to deliver electricity through a length of the conduit. The fluid delivery system further includes master hub disposed on a fluid delivery device. The fluid delivery system also includes at least one slave hub disposed on the conduit and communicatively coupled to the master hub.

A localized product injection system includes a composite boom tube having a carrier fluid passage within a tube body, and at least one injection product passage within the tube body isolated from the carrier fluid passage. A plurality of port stations are provided at locations along the tube body. Each of the port stations includes a carrier fluid outlet port and at least one injection product outlet port. A localized injection interface is coupled at a port station. The injection interface includes a carrier fluid input coupled with the carrier fluid outlet port, and at least one injection product input coupled with the at least one injection product outlet port. The injection interface includes at least one throttling element in communication with the at least one injection product input, a mixing chamber, and an injection port configured for localized coupling and injection to a product dispenser.

A plural component system includes a first pump configured to pump a first constituent material to an applicator and a second pump configured to pump a second constituent material to the applicator. A controller is operatively connected to the first pump and the second pump to control operation of the first pump and the second pump to pump the first and second constituent materials to the applicator at a desired ratio.

A water outlet mechanism for adjusting a mixed ratio of a functional liquid comprises a water operated pump driven by water power, a functional liquid storage chamber, a water outlet channel, a water inlet channel, and a flow rate adjustment mechanism. A liquid inlet of the water operated pump is in communication with the functional liquid storage chamber, a liquid outlet of the water operated pump is in communication with the water outlet channel or the water inlet channel, and the flow rate adjustment mechanism is configured to adjust a water flow rate of the water in the water inlet channel for driving the water operated pump so as to change a suction frequency of the water operated pump.

A admixing system for fire extinguishing systems for producing an extinguishing agent-extinguishing agent additive mixture (premix) by mixing an extinguishing agent additive with an extinguishing agent. The admixing system has a motor that can be driven by a flow of extinguishing agent, an admixing pump connected to the motor for pumping the extinguishing agent additive, an admixing line, and an extinguishing agent additive line, from which the extinguishing agent additive is mixed with the extinguishing agent in the admixing line. The admixing system has a branching line, from which a part of the flow of extinguishing agent can be branched off if the load in the fire extinguishing system only requires a small flow of extinguishing agent. In this manner, the flow of extinguishing agent flowing through the motor is artificially increased so that the motor runs in a higher rotational speed range in which a reliable operation of the motor is ensured (a so-called start-up flow reduction). The admixing system has a motor rotational speed measuring device and a controller, said controller being designed to completely or partly open and/or close the branching valve on the basis of the motor rotational speed measured by the motor rotational speed measuring device.

An assembly for delivery of mixed chemical for use in a vehicle wash system includes a chemical delivery device for dispensing chemical having a piston with a one-way valve and a pneumatic drive mechanism; and a fluid delivery manifold configured to deliver motive fluid for mixing with the dispensed chemical having an integrated valve with a valve plunger therein configured to be pneumatically actuated. During a dispensing operation, chemical and fluid are dispensed and mixed at a mixing site of the assembly. During a resetting stroke of the chemical delivery device, the drive shaft and the piston are pneumatically retracted away from the outlet to a retracted position, and the one-way valve is in an open state and permits passage of chemical through the one-way valve for dispensing from the chemical chamber in a subsequent dispensing operation.
