. Handling Precautions

1. Operating Fluid and

Temperature Range

1) Operating uid

Values shown in this catalog are based upon using

mineral oil based anti-wear hydraulic uid. To

ensure optimal performance use of mineral oil

based anti-wear hydraulic uid is recommended.

2) Viscosity and temperature range

To minimize both oil and seal deterioration, a

maximum operating temperature of 60

should

be considered. Please note that the regulator

may become slow to respond when operating

at low temperatures (below 20

) in extreme

cold environments. At such low temperature it

is strongly suggested that a warm up cycle is

introduced until an operating temperature of 20

is achieved.

2. Filtration and Contamination

Control

1) Filtration of working oil

The most important means to prevent premature

damage to the pump and associated equipment

and to extend its working life, is to ensure that

hydraulic uid contamination control of the system

is working effectively.

This begins by ensuring that at the time of

installation that all piping, tanks etc. are rigorously

cleaned in a sanitary way. Flushing should be

provided using an off line ltration system

and after ushing the lter elements should be

replaced.

A full ow return line lter of 10 micron nominal

should be utilised to prevent contaminant ingress

from the external environment, a 5 to 10 micron

lter with the tank's breather is also recommended.

2) Suggested acceptable contamination

level

The relationship between contamination level and

pump life is very difcult to predict as it depends

on the type and nature of the contaminant present

in the system. Sand or Silica in particular, due to

its abnrasive nature, does signicantly reduce the

expected life of a pump. Based on the precondition

that there is no signicant presence of Silica type

substances then a minimum Cleanliness level of

-/18/15 ISO 4406 or SAE AS 4059E Table 1 Class 9

(NAS 1638 Class 9).

5

3. Drive Shaft Coupling

Alignment between the prime mover and the pump shaft should be within 0.05 mm TIR*. In case the pump is

directly coupled to the engine ywheel, use a exible coupling.

*TIR = Total Indicator Reading

4. Oil Filling and Air Bleeding

1) Pump case lling

Be sure to ll the pump casing with oil through the drain port, lling only the suction line with oil is totally

in-sufcient. The pump contains bearings and high-speed sliding parts including pistons with shoes and a

spherical bush that need to be continuously lubricated. Part seizure or total premature failure will occur

very quickly if this procedure is not rIgidly followed.

2) Air bleeding

Run the pump unloaded for a period to ensure that all residual air within the system is released.

3) Long term out of usage

It is undesirable to leave the pump out of use for a long period e.g. a year or more. In such a situation it is

recommended that the pump is run for a short period on a more frequent basis even if it is just unloaded.

With regard to a pump held in storage then rotating the shaft on a frequent basis is sufcient. If the pump is

left out for more than the suggested time it will require a service inspection.

5. Drain Piping

1) Installation of drain line

It is the preferred option to mount the pump with the case drain piping initially rising above the pump

before continuing to the tank. Do not connect the drain line to the inlet line.

The uppermost drain port should be used and the drain piping must be larger in size than the drain port

to minimise pressure in the pump case. The pump case pressure must not exceed 0.1 MPa as shown in the

illustration below. (Peak pressure must never exceed 0.4 MPa.)

Cautions

A) Inlet and drain pipes must be immersed by

200 mm minimum from the lowest level under

operating conditions.

B) Height from the oil level to the centre of the

shaft must be within 1 meter maximum.

C) The oil in the pump case must be relled when

the pump has not been operated for one month

or longer.

. Handling Precautions

Fluid level

Must be higher than

2) Size of drain hose or drain pipe

The internal bore size of the drain hose or drain pipe must be larger than that of the drain port. Arrange the

drain line as short as possible.

7. Shaft Loading and Bearing Life

Although K3VLS pumps are equipped with bearings that can accept some external thrust and radial forces,

application of such loads will affect bearing life. Depending on the load magnitude , the load position, and

the load orientation, bearing life may be signicantly reduced.

Load Sensing and Pressure

Cut-off

(Ordering Code [9]: L0 / L1)

This regulator has function of ow and pressure

control (i.e. load sensing control and pressure cut-

off control.)

To control ow a variable orice is used. (A

variable orice is not included in the pump and

shall be prepared separately.) Pump displacement

is controlled to maintain the differential pressure

across the orice constant. The ow is controlled

to a required ow regardless of pump delivery

pressure. In addition, there is a pressure cut off

function incorporated into the control. The pressure

cut-off function overrides the ow control function.

L0 control: with a bleed off orice

L1 control: without a bleed off orice

Releasing the pressure at port PL results in standby

condition, which provides zero ow at unloading

condition. The unloading pressure is typically

0.1 to 0.2 MPa higher than differential pressure

setting.

2-2 Functional Description of Regulator

Electric Inverse Proportional

Pressure Control

-Voltage:24V, Deutsch Connecter

(Ordering Code [9]: PR2)

This regulator is Electro-hydraulic pressure

control type of regulator. A current is input from

the controller to the solenoid of the regulator,

and the pressure is controlled by the inverse

proportional solenoid valve. Since the regulator

tries maintaining the pressure which is set by the

valve, the pump discharge is controlled according

to the load of the actuator. Thus, the pump supplies

only the amount of hydraulic oil required by the

actuator. Even if the input current to the solenoid

becomes zero at the electric failure of the machine,

the pressure set will be maximum, and the pump

displacement will be also maximum, so it functions

as electric fail-safe.

The pressure of cut-off valve can be set between

28MPa and 10MPa. The control effective range of

the solenoid is decided by the cut-off valve setting.

(e.g. in case the cut-off setting is 20MPa, the

control range is 230mA - 500mA.)

When the "00" option is selected in section 11 of

the model code the K3VLS pump is supplied as a

torque limit ready pump. The pump has a blanking

plate tted instead of the torque limiter. This offers

better exibility to congure the pump as required.

The pump as ordered will function as a load sense

or pressure compensated pump depending on your

selection of ow control in section 9 of the model

code. If the torque limit blanking cover is then

replaced with a torque limit regulator the pump

has the torque limit control functionality. Note that

the torque limit regulator would need to be set.

2-2 Functional Description of Regulator

Pressure Cut-off

(Ordering Code [9]: P0)

This regulator has function of pressure control.

As discharge pressure rises to the cut-off setting,

the pump displacement is reduced to prevent the

discharge pressure from exceeding and keep the

set pressure. It is imperative that a safety relief

valve be installed in the system.

By connecting the Pc port to a remote pressure

control relief valve, variable pump pressure control

can be achieved.

The remote pressure control relief valve is to

be set to 1.5 MPa below to the required system

pressure.

The remote control relief valve is out of scope of

supply.

Torque Limiter

(Ordering Code [11]: A)

L0/L1 control functions as previously noted. In

response to a rise in delivery pressure the swash

plate angle is decreased, restricting the input

torque. This regulator prevents excessive load

against the prime mover.

The torque limiter is comprised of two springs that

oppose the spool force generated by the system

pressure. By turning the adjustment screws, the

appropriate input torque limit can be set.

Torque limiter control setting is shown in the

attached table, and the torque limiter can be

adjusted by the torque value of the table. Refer to

the instruction manual for adjustment.

2-2 Functional Description of Regulator

The electric displacement control enables the

pump displacement to be changed according to the

change of input current to the solenoid. The pump

displacement can be adjusted in proportion to the

input current between the input current of I

1

and I

2

(refer to control curve).

With fail-safe function, at loss of input current in

such case of brakage of electric wires, the pump

displacement becomes maximum automatically.

Even under this condition the load sensing and

pressure cut-off control can be operated.

The fail-safe function is designed only for usage in

short period for emergency. Necessary repair is to

be made in the soonest opportunity.

For the hydraulic circuit refer to page 26.

Note for start up

Due to its structure, the electric displacement control

requires larger input current than I

at start up, then

normal proportional control can be achieved between I

.

Minimum operating pressure

With fail-safe function, in order to ensure safety and

repeatability of control the minimum operating pressure

of 5 MPa is to be secured. This avoids switching the

pump to fail-safe mode unexpectedly.

Input current ramp time requirement

With fail-safe function (Ordering code: E2, E3), ramp time

of 200 msec or larger is to be secured.
