This system was designed after many years of trying to resolve dirt and dust accumulation in confined areas on mobile and stationary equipment, and other types of plant equipment, including equipment of offshore oil and gas platforms, maritime vessels, and others, and more generally any kind of motorized or mechanical equipment with internal areas that accumulate dust and dirt. The areas where dust and dirt accumulation occur would normally only be accessible by removing major components. The initial installation of the wash system may be time consuming, however, may eliminate future risk exposure and manning. The system may be designed to utilize existing pressure washers and air systems. The supply manifold may be constructed from steel, hydraulic lines, pressure wash nozzles and angled fittings. The installer may assess areas of accumulation, directing the nozzles at the general area. Once the system has been installed, mechanical operators may easily attach the device to a pressure source. Quick connect fittings would be installed outside the machine, connecting pressurized water or air to the supply manifold.

The present disclosure discloses a surface cleaner, including a connector, where a rotary valve sleeve is connected to the bottom of the connector, a rotary valve core is connected to the interior of the rotary valve sleeve, a valve body is connected to two ends of the rotary valve core, a rotating valve core is connected to the bottom of the valve body, a water outlet pipe is connected to the bottom of the rotating valve core, and a nozzle is connected to each of two sides of the water outlet pipe. The surface cleaner disclosed in the present disclosure has the advantages of compact structure, stable performance, low cost, long service life, high safety, and wide use range, and is capable of meeting the requirements of a long service life for commercial use and a low price for household use.

The present disclosure relates to the field of power drill accessories; in particular, a plurality of drill-powered tools for use in a variety of home and construction-related applications. Certain aspects of the present disclosure provide for a drill-powered apparatus comprising a hex shank configured to be selectively coupled to a chuck of a power drill; a drive assembly operably engaged with the hex shank, wherein the drive assembly is configured to be rotatably engaged via the hex shank; and at least one functional component operably engaged with the drive assembly, wherein the at least one functional component is configured to perform at least one function in response to rotation of the drive assembly.

An apparatus for simultaneously rolling up and washing hoses. The apparatus has at least one nozzle and one bristle for washing and scrubbing a hose as it is being rolled onto a hose reel. The apparatus can be connected to a standard garden hose or to a water source on a fire truck. The apparatus washes and scrubs a hose of decontaminates as it is being rolled.

Disclosed herein are a priming system, a substrate cleaning module having the priming system, and a method of operating the substrate cleaning module. The priming system includes a diversion valve configured to selectively direct a flow of an agent; a priming nozzle mechanism coupled with the diversion valve; and a separation chamber coupled with the priming nozzle mechanism. The priming nozzle mechanism includes a releasing nozzle configured to release the agent inside the separation chamber, and the separation chamber is configured to process the agent. The method of operating the substrate cleaning module includes operations to redirect an agent from a dispensing nozzle to a releasing nozzle during a time period when the dispensing nozzle stops dispensing the agent. The method further includes operations to continue dispensing the agent by the releasing nozzle during the same time period when the dispensing nozzle stops dispensing the agent.

A plunger pump includes a base and a motor. The base is provided with a first pump body and a second pump body. The flow rate of the first pump body is equal to the flow rate of the second pump body. The first pump body is connected to a first motor. The second pump body is connected to a second motor. The first pump body is equipped with an inlet channel, one end of the inlet channel is equipped with a common inlet port, the second pump body is equipped with an outlet channel, one end of the outlet channel is equipped with a common outlet port, the inlet channel is set on the side far from the first motor, and the outlet channel is set on the side far from the second motor.
