SINGLE LINE SYSTEM
Characteristic of Single line system
All supply lines (pump - distribution valve - bearing) consist of a single piping line.
2 If even one of the lubrication points is blocked, the distributor valve piston will not operate and themain pipe pressure will rise, signaling an abnormality, thus ensuring that all points are lubricated.
3 By selecting the distribution valve piston, the required amount of lubricant for each point is set atthe planning stage.

MONITORING ITEMS
It is diﬃcult to check the operation of distribution valves scattered over a wide area without fail. In addition,
distribution valves may be installed in high or hazardous locations. Monitoring items enable the operating
status of distribution valves to be checked quickly and accurately.

Wireless monitoring system for Dual-line distribution valves

Wiring costs can be reduced by using wireless technology to monitor the status of distribution valves.
Troubles caused by poor lubrication can be avoided by monitoring the entire system via PC or PLC.

System Overview

The status of the indicator
rod is periodically transmitted
to the receiver.

PatentedNo. 7144815
No. 7144816

Sensor detects the movement ofthe indicator rod.

Received status
information ismonitored on aPC or PLC.

Line-of-sightdistance approx.
500 meter

Basic features of the system●It uses 920 MHz band speciﬁed low-power (LPWA) radios. The communication distance is approximately 500 meter in a line-of-sight environment. (Our experimental values)●The transmitter is battery-powered and requires no wiring. One battery (Lithium thionyl chloride AA battery 3.6V) provides about 3 years of continuous use.
(Conditions: when monitoring is carried out every 3 hours) *The signal conditions vary greatly depending on the installation environment. Please contact us for priorveriﬁcation of radio wave conditions.

Oil Air System
Oil air system provides a continuous supply of a small amount of oil along acontinuous compressed air ﬂow in the tube. Our original distribution valve
precisely supplies a small amount of oil, which is mixed with the air ﬂow by amixing valve. The oil spirals continuously along the tube wall and reaches thebearing. Due to the sealing eﬀect of the compressed air, the bearings areprotected against debris and, what is more, do not contaminate the surrounding
environment and atmosphere like grease or oil mist.

System conﬁguration

Characteristic

Oil-air systems can be broadly divided into dual-line and single-line systems.
The system consists of an oil unit, control panel, mixing valves, distributor andmulti-connectors for hose detachment.
Proposals can be made according to oil-air monitoring and the size of theinstallation.

1 Sealing eﬀect extends bearing life.

2 Reduces oil consumption and the costs

compared to oil mist.

The oil ﬂows through the pipe
in a liquid state and does not
generate a mist.

3 Reliable distribution valves ensure that theright amount of oil is delivered precisely.

4 The equipment surroundings are kept

clean as there is no mist dispersal.

5 Due to fewer restrictions on pipework installation,

oil air can be supplied even where there are pipe rises.

Oil bearing

Grease Bearing

By oil-air system, the condition of the bearings is easier to see and themaintenance is much easier.

Chain lubrication (KIP series)
Injection pump systems are the ideal lubrication solution forsmall to large conveyor chains. The system injects the rightamount of oil at the right time and in the right quantity at thespeciﬁed point by activating the pump while sensing the timingwith a proximity sensor.

System Conﬁguration

Characteristic

1 The non-contact system has no eﬀect on the chain.

2 The right amount of spray prevents oil ﬂow misting and reduces

contamination of the surrounding environment. In addition,
the pinpoint spray minimizes oil adhesion to the productson the conveyor.

3 Various control options can be selected, including manual

start/stop and automatic start/stop.

High-precision Oil Flow with ﬂow control function (KOF series)
Conventional feed-oﬀ lubricators
had diﬃculties in adjusting theﬂow rate, and only skilled
operators can do it properly,
resulting in problems such as
oil shortages, over-supply anduneven lubrication.

Main characteristics
・Equipped with a rod for cleaning the glass tube.

・Easy ﬂow rate adjustment even during operation.

・Flow rate can be adjusted by the measuring cone
and the height of ﬂoat in the glass tube, and isvery accurate and reliable.

Even under the harshest conditions
in paper and pulp mills, the oil ﬂow
can be adjusted easily, reliably andquickly by anyone thanks to aunique mechanism.
The oil ﬂow can be unitized asshown in the picture to allow
installation in tight spaces on theside of the machine.

・The diﬀerent sizes of 10A and 15A can beincorporated in the same body・Flow abnormalities can be identiﬁed at a glance.
Models with a contact switch to signal ﬂow
abnormalities are also available.
・High performance is guaranteed even in hightemperature and harsh environment such as
paper and pulp mills.
Also it is applied for reduction gears.

※Size of oil ﬂow unitization depends on thenumber of points and the presence orabsence of an abnormality detection
assembly box, so please contact us formore information.

Dedicated catalogues are available for each product; please contact our branches or distributors for more details.
