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).
