Abstract:
A parts washer is disclosed. The parts washer includes a housing that has a washbasin or wash chamber defining an inner cavity and chargeable with a volume of fluid. A spray tube is rotatably positioned within the housing and has an axis of rotation. The spray tube is configured to define a volume of rotation as it rotates about its axis of rotation. A support structure configured to support parts to be washed is positioned within the housing and is substantially within the volume of rotation of the spray tube. The parts washer further includes a pump connected to the spray tube. The pump delivers fluid under pressure to the spray tube. The spray tube includes a plurality of outlets configured to direct fluid toward parts to be washed on the support structure and at least one outlet configured to direct fluid in a direction to cause fluid-propelled rotation of the spray tube about its axis of rotation. The parts washer may further include a heater, a first thermostat for measuring the temperature of fluid in the parts washer and automatically disengaging the heater if the temperature of the fluid exceeds a defined maximum temperature, and a second thermostat for controlling the heater to maintain the temperature of fluid in the parts washer between defined upper and lower temperatures. Furthermore, the parts washer may include a pressure switch for disengaging the pump and/or the heater if pressure from fluid in the parts washer is less than a defined minimum pressure, and an auxiliary spray tube that is adjustably mounted on the spray tube and includes a second plurality of outlets.
