Jet Cleaner TANKO-JM
3.2.3 Function of the JM800
The item numbers shown in brackets refer to Figure 7.5-3: Internal construction of the JM800-G13.
The cleaning fluid enters at the connection cover (01) and flows through the holes of the flow-in disk (14) into the inside of the device in order to cause turbulent movement underneath the flow-in disk in the liquid around the rotor shaft (15). The liquid flows downwards on the outside of the rotor shaft (15) and hits the rotor impeller (16). The rotor shaft is set into rotation via the impeller. The liquid then flows through the side bores in the rotor shaft (15) into the shaft-axle connection (19) and is distributed through the bores in the axle (20) for nozzle carriers (22). From there, the fluid passes through the nozzle openings (11) and back out again. Any leakages from the cleaning device are used for the device’s self -cleaning. The rotation of the rotor shaft (15) causes an orbital rotation of the nozzle carrier around the rotor shaft. A simultaneous rotational movement of the nozzle carrier around the axle of the nozzle carrier is triggered by the gearing of the bevel gears (18; 21). The different number of teeth in the bevel gear wheels causes an offset in the nozzle position with each revolution and thus the initiation of a 360° spray angle.
JM800 cleaning times:
The speed of the cleaning head varies depending on the volume flow rate which is determined in particular by the number of nozzles, the size of the bores in the nozzles and by the pressure of the cleaning agent. – If the entry pressure is 5 - 13 bar (73 - 189 psi), the speed of the cleaning head is 5 - 20 rpm. Fluctuations of 10 – 15% are to be expected due to the design. – A complete cleaning cycle is completed after 45 revolutions. At a speed of 5 rpm, 9 minutes are required for a complete cleaning cycle. – In order to determine the cycle time, divide the number 45 by the number of revolutions of the cleaning head per minute.
3.3 Technical Data
The estimated safe service life of the device is 10 years with single-shift operation and the use of drinking water. Prerequisite for this: the device must be maintained properly at the intervals specified in the section 7.4 Maintenance , and the wear parts must be replaced regularly.
Aggressive agents can reduce the service life of the device.
