Replacement timing of consumable parts of the spinner high-pressure pump
When the spinner high-pressure pump is used for a long time, the cap seal, U-
packing and wear ring of the pump become worn and causes a degradation of
pressurization effect.
In this case, it is necessary to replace the cap seal, U-packing and wear ring as
the consumable parts.
To know the standard replacement timing, calculate the hours and days of use
as follows.
[Standard replacement timing (hours)]
Obtain the standard replacement timing after use in hours, h, using the
following expression (5.1.1).

h: Hours of use (h)
p: Discharge pressure of the pump (MPa)
If the hours of spinner cleaning reaches h, replace the cap seal, U-packing and
wear ring.
[Standard replacement timing (days)]
If the cleaning time for one workpiece is constant, you can obtain the standard
replacement timing after use in days, d, using the following expression (5.1.2).

n: Number of workpieces cleaned a day (pcs)
If the number of days of the machine operation accompanied with spinner
cleaning reaches d, replace the cap seal, U-packing and wear ring.

Operation flow
If the pressure does not rise even when the pressure pump works properly, the
parts inside the pump may be worn.
The procedure for replacing the consumable parts of the spinner high-pressure
pump consists of the following steps.
5-1-1 Removing the machine outer cover
5-1-2 Disconnecting piping of the spinner high-pressure pump
5-1-3 Replacing the consumable parts of the spinner high-pressure pump
5-1-4 Completion of replacing the consumable parts
of the spinner high-pressure pump
Before replacement
Have on hand the following item for replacing the consumable parts of the
spinner high-pressure pump.
3mm Allen wrench
5mm Allen wrench
