1 –Introduction
Parts washers machines are an integral part of modern production processes. Using water-based
chemical solvents that act on cleaned surface under pressure, greasy debris are released and washed
out. To increase the effect of this process, the wash liquid is heated to an optimum temperature.
2 –Description
ADS 800 parts washers machine (hereinafter referred to as the "machine") is used for technical
washing of components, parts or machine units (hereinafter referred to as "parts"). Washing is
performed from two opposite directions by hot wash liquid sprayed on cleaned items, placed in a
rotating wash basket, from the top and bottom.
The oil film from the wash liquid can be collected using additional machine equipment, so-called oil
skimmer.
A uniform system of designation is used in illustrations and the subsequent description of the structural
layout of individual parts and nodes of the machine:

2.1 Standard machine version
2.1.1 Lid and working group
The machine housing is divided into two standard parts; see Figure 1. They consist of a
movable lid (pos. 1-2) and a fixed working group (pos. 1-1). Both parts are made of stainless
steel (ČSN 17 240).
The working space is located inside the lid and working group.
The working group is divided by removable grids, refer to Figure 1 (pos. 1-71, 1-72). Above the
grids there is a working space in which the technological processes of washing of parts take
place. Under the grids there is a wash liquid tank with a filter, refer to Section 2.1.2.
The lid is suspended on two hinges, see Fig. 3 (position 3-1) allowing its complete closure. Both
of the hinges are secured with locking rings against being pulled out of the eyelets (pos. 3-92.1).
The operator controls the opening and closing of the lid manually. The lid is secured against
spontaneous opening by means of a lock, so-called front closure lever; see in Fig. 1 (pos. 101).
A handle is screwed to the lid to facilitate its handling (pos. 1-102). Damping gas struts are
installed between the lid and the working group to alleviate the weight of the lid, see in Fig. 2, 4
(pos. 2-102). The strut hinges are anchored to the pins welded to the wall of the working group
and of the lid.
Sealing between the working group and the lid is achieved using a flexible lid seal put over the
peripheral edge of the working group; see in Fig. 5 (pos. 3a-62).
2.1.2 Oil skimmer
When parts containing residual oil are washed, a floating oil film forms on the wash liquid
surface. It is removed mechanically using additional machine equipment, so called oil skimmer,
see in Fig. 2a. The unit consists of an oil skimming belt (position 2a-101) suspended vertically
on a drive roller (pos. 2a-7) driven by an electrical motor. A balance roller is suspended on the
lower end of the belt (pos. 2a-5). Droplets of oil are carried by the belt in between teflon blades
(pos. 2a-6). When wiped off the belt, the droplets flow through a trough into a pipe with screw
fitting (pos. 2a-4), into which an oil discharge valve is screwed (pos. 2a-51).
Torque from the transmission (pos. 2a-41, M1) is transmitted on the drive roller using a shaft
(pos. 2a-2) mounted in a bearing housing (pos. 2a-1). The drive shaft is inserted in the bushing
in the transmission and secured against shifting by a screw with a washer (pos. 2a-93.1 and 2a-
93.2). On the other side, it is secured by a locking ring (pos. 2a-91.1) inserted in the groove in
the shaft. The shaft passes through a shaft sealing ring (pos. 4e-61) preventing liquid
penetration into the inner parts of the bushing. The end of the shaft is provided with the drive
roller (pos. 2a-7).
The left side wall of the working group contains a cut-out to which the oil skimmer unit (pos. 2a-
3) is fixed by means of screws and nuts (pos. 2a-94.1÷2a-94.3). It is sealed by a rubber seal
(pos. 2a-62) to prevent leaking of wash liquid from the work space of the working group. The
flange with the transmission (pos. 2a-1) is mounted on the inside using four screws with
washers (pos. 2a-95.1 ÷ 2a-95.3).
The internal section of the oil skimmer unit is covered (pos. 2a-71).
2.1.3 Basket and its drive
Washing of parts proper takes place after they are inserted in the washing basket, see in Fig.
2b, 2c (pos. 2b-5). The basket is formed by a wire structure with a reinforced bottom. The centre
of the basket is formed by a tube slid on the so-called bearing pivot, see in Figure 2c (pos. 2c-
1). The upper part of the pivot passes through a plastic and metal washer (pos. 2c-91.1 and 92-
1): A cotter pin (pos. 2c-93.1) is inserted in a hole in the pivot and secured, holding the basket
on the housing.
The bearing pivot is inserted in the tube connected to the support by welding, see in Fig. 2c
(pos. 2c-1). A lid with the central tube pin is welded from the top. Attached to the tube are axial

P a g e 14 | 61
and radial bearings (pos. 2c-2 a 2c-3), both of which are inserted in the tube centre of the
basket.
The transmission of torque from the transmission, see in Fig. 2b (pos. 2b-41, M2), on the pinion
gear is ensured by a shaft (pos. 2b-2) mounted in the bearing bushing (pos. 2b-1). The drive
shaft is inserted in the bushing in the transmission and secured against displacement by a
screw with a washer (pos. 2b-93.1 and 2b-93.2). On the other side, it is secured by a locking
ring (pos. 2b-91.1) inserted in the groove in the shaft. The shaft passes through a shaft sealing
ring (pos. 2b-61) preventing liquid penetration into the inner parts of the bushing. A pinion gear
is set on the end of the shaft (pos. 2b-3).
The body of the bearing bushing is attached to the left side wall of the working group by screws
with washers (pos. 2b-94.1÷ 2b-94.3). It is provided with a rubber seal preventing leaks of liquid
from the working space of the working group (pos. 2b-62). A transmission with an electric motor
(pos. 2b-92.1 and 2b-92.2) is attached to the bushing from the outer side.
2.1.4 Washing system
The wash liquid flows in two circuits, see in Fig. 3, 3a:
- Suction circuit consists of a removable filter (pos. 3a-3), which prevents dirt from entering the
pump, a closing valve (pos. 3a-511), a quick coupling (pos. 3a-101) and a pump (pos. 3a-M1).
The pump is attached to a bracket in the rear section of the working group.
The suction duct is sealed by a rubber collar at the inlet of the filter (pos. 3a-61). The filter
itself can be easily dismounted after sliding out of its holders.
- Discharge circuit consists of an outlet from the pump, a discharge duct and spraying nozzles.
After passing through the pump (pos. 3a-41), it enters the washing space in the force of a
discharge hose (pos. 3-). Here, the liquid is divided into two flows. One part of the liquid flows
into the lower spraying nozzle (pos. 3a-1) and the other part of the liquid passes through the
central ... into the upper spraying nozzle (pos. 3a2). To facilitate cleaning, both ends of the
duct are provided with a removable plug (3a-91.1).
- Accessories of the washing system
A drain valve (pos. 4-51) is used for draining of washing liquid out of the machine, see in Fig.
4. A safety plug (pos. 4-102) is screwed into the drain valve to prevent accidental leaks of
wash liquid due to insufficient closing of the valve.
A level gauge is mounted to the left side wall of the working group (pos. 3a-4) to check the
level of liquid.
2.1.5 Electrical system
It consists of an electrical switchboard cabinet, control and power elements, electrical motors,
heater, electric sensors, protective devices, and cable distribution systems. The use of
electronic modules allowed high comfort of machine operators with minimum requirements for
operation.
- The electrical switchboard, see in Fig. 1 and 4 (pos. 4-1), consists of a stainless steel cabinet
with an openable door secured by two locks (pos. 4-103) protecting the machine operator from
accidental contact with live electrical circuits. A seal (pos. 4-61) is inserted between the door
and the cabinet to protect the internal parts of the cabinet against water ingress. There is a
main switch on its front side.
- There are electrical control and indication parts, lucidly arranged with function legends
installed in its upper side; see in Fig. 8.
- The wash liquid heating and the washing are fully automated. Technological processes of the
machine are controlled depending on the setting of the control unit actuators. Operating
personnel is informed on an ongoing process by means of indicator lights and data displayed
on the control unit display, described in Section 5.1.
- Wash liquid heating is ensured by an electric submersible heater, see in Fig. 4 (position T1).

P a g e 15 | 61
- Next to the heating element, an electrical box is attached to the wall of the working group, see
Fig. 2 (pos. 2-101), and in it a pipe with a liquid temperature sensor (pos. RT1) passes through
the wall of the working group, which maintains the temperature of the wash liquid at the set
value. Together with the sensor, a thermal fuse probe (pos. ST1) is located in the sump. It is
part of the safety circuits of the machine. If the regulation fails, the liquid temperature starts to
rise dangerously. When 95 °C is exceeded, the thermal fuse is breached, interrupting the
power supply to the heating element, and further heating of the liquid is stopped. When the
temperature drops, the thermal fuse remains open and must be manually reset once the fault
is corrected.
- The minimum level sensor, see in Fig. 2 (pos. HS1), is part of the safety circuits of the
machine. When the liquid level drops below the safe limit, the so-called level relay interrupts
the washing process or prevents its starting.
- A safety switch of the lid, see in Fig. 2 (pos. SQ1) is installed between the lid and the working
group in order to enhance safety of operating personnel during the technological processes of
washing. When it switches off, the safety circuit terminates the cycle in process, and when the
lid is open, the switch blocks accidental starting of the machine.
- Cable distribution systems are placed in cable troughs and electrical boxes to minimise the risk
of their mechanical damage. The mains supply includes a power cable terminated with a five-
pole mains plug, see in Fig. 4 (pos. 4-101), suitable for use in industrial plants. The mains
parameters must comply with the requirements of Section 3.
- With regard to the working environment of the machine, an additional earthing and bonding
protection against electric shock is provided. There is a screw for connection to an earth cable
on the machine housing near the electric switchboard, see in Fig. 4 (pos. 4-91.1 and 4-91.2).
