SYSTEM DETAILS

Wash Cabinet

Design of the machine consists of a cabinet that houses the Washer’s turntable and spray system. The cabinet is mounted on top of the wash tank, and this cabinet/tank weldment forms the main structure of the machine.

The cabinet is fabricated from 12 gauge 304 stainless steel sheets and structural reinforcing members using all-welded construction to provide a water-tight, first-rate appearance. The interior of the cabinet includes a sloped pan bottom used to direct sprayed wash solution through a removable stainless steel chip tray before return to the wash tank.

Access by the machine operator to the “work area” inside the cabinet is gained by opening a hinged door on the front of the machine. The bottom of this 12-gauge 304 stainless steel door includes a small trough that directs collected wash solution back to the cabinet to prevent liquid from getting on the floor while the door is open. The door also includes a manually-operated latch and a safety limit switch that disables the pumps if the door is opened during a cleaning cycle.

Turntable

The turntable weldment is fabricated from 304 stainless steel and is supported by tapered roller bearings that are mounted within a stainless steel spindle and hub assembly. The center of the turntable bolts to the top of the spindle/hub assembly and includes a metal deck suitable for placing basket of parts to be cleaned.

The turntable is friction driven by a 1/4 HP 90 Volt DC gearmotor located outside of the cabinet on the back of the machine. A horizontally-mounted rubber wheel mounted to the gearbox output shaft extends into the cabinet and drives the turntable on its perimeter. During the automatic washing sequence, the turntable rotates at approximately 3 RPM while the machine runs through its timed cleaning cycle.

Wash Tank

The solution tank of the Washer has a capacity of approximately 100 gallons and is fabricated from stainless steel and structural reinforcing members using all-welded construction. The tank is located beneath the wash cabinet, and along with the cabinet forms the main structure of the machine. Floor pads on the underside of the tank allow the entire machine to be picked up and moved via forklift, and the tank is approximately 9″ wider than the cabinet along back of the machine providing open tank area for mounting the top-pull-out wash pump. The tank also includes a sloped bottom that runs to a sump area, and a 1-1/2″ drain fitting.

Spray System

The wash pump is a Gusher brand vertical, end-suction, centrifugal unit with cast iron housing and impeller, complete with a 5 HP, 3450 RPM motor. The pump is capable of delivering solution to the spray system at a rate of up to 80 GPM @ 45 PSI.

The Washer’s spray system consists of a stainless steel header pipe assembly that has tapped holes to accept Spraying Systems brand “V-Jet” spray nozzles made of stainless steel. The headers are arranged to provide top, bottom, and side spray within the wash cabinet.

Rinse System

The rinse tank has a capacity of 50 gallons and is fabricated from 12 gauge 304 stainless steel and structural reinforcing members using all-welded construction. The free-standing tank is located alongside the machine (next to the wash tank), and sprayed rinse solution drains from the wash cabinet back to the rinse tank through the air-operated drain diverter located within the wash cabinet. Floor pads on the underside of the rinse tank allow the unit to be picked up and moved via fork lift during installation. The tank includes removable stainless steel covers for tank access along with stainless steel brackets for mounting the top-pull-out rinse pump.

The rinse pump is a Gusher brand vertical, end-suction, centrifugal unit with cast iron housing and impeller, complete with a 2 HP, 3450 RPM motor. The pump is capable of delivering solution to the spray system at a rate of up to 40 GPM @ 28 PSI.

The rinse spray system is similar to the wash spray system, with one set of stainless steel header pipes arranged to provide top, bottom and side spray within the cabinet.

RCW Electrical

Electrical Controls

Electrical controls are housed in a Hoffman (or Saginaw) brand NEMA 12 enclosure mounted on the side of the wash cabinet (as room permits, otherwise enclosure is free standing). Components within the enclosure are finger-safe and are Allen-Bradley brand unless noted otherwise. Components include a main disconnect switch, Littelfuse fuse holders and branch circuit fuses, terminal strips, a
G.E. (or equal) transformer to provide a 115 Volt control circuit, master control relay, Minarik 90 Volt DC motor controller (for the turntable drive), heating system contactor, and an IEC-style motor circuit protector with thermal overload and short circuit protection.

An equipment power on pushbutton, an emergency stop pushbutton are provided on the front door of the main electrical enclosure, along with the reservoir heating system’s Watlow digital temperature controller. Machine start/stop controls are provided on the side of the enclosure facing the front of the machine. Buttons and lights are Allen-Bradley brand.

The machine is wired per NEC (NFPA 70) and NFPA 79 electrical standards, ready for connection to your electrical service.

Electric Heat

Electric Heat for Wash/Rinse Tank. Consists of (2) Indeeco brand 12 kW screw-plug immersion heaters capable of heating tank contents from 70 to 140 degrees (F) in one hour. The heaters have stainless steel elements and fittings, with cast iron NEMA 4 conduit boxes. One heater is located in the wash compartment and one heater is located in the rinse compartment. The Rinse heater is made from Incoloy to be used with straight water.

A Watlow brand temperature controller mounted on the door of the main electrical enclosure provides digital read-out and control of solution temperature in the wash tank. A stainless steel type-J thermocouple located in the tank provides an input signal to the controller, which switches the heaters on and off to maintain setpoint temperature.

Insulation for Heated Wash Tanks. Consists of a 2″ thickness of fiberglass batting on all exterior tank walls, held in place by a 14 gauge stainless steel jacket. Also includes stainless steel covers for open areas of tank.

Bag Filtration

Bag Filtration System for Wash Station. Consists of a floor-mounted size 4 bag filter housing and a filter bag rated at 50 microns (other ratings are available). The unit is piped between the spray pump and the spray nozzles in the wash station. The housing includes an internal basket for holding one filter bag, and the hinged cover is held in place with three eyebolts. Inlet and outlet pressure gauges are also provided.
