Dynamic balances and makes modifications

Motion balances and makes modifications [repair summary]
The centrifuge (decanter) is required and performs it with other rotary machines as needed. We turn a turbine blade on a device called a balancer and measure quantity of imbalance and take it and regulate a class of the balance to a need level by scraping off the imbalance quantity mainly.

We introduced a new dynamic balance machine several years ago.

■ Measurement unit
Measurement unit With a measurement unit for balancing machines which adopted a digital control technology,we realize highly precise fishing alignment by simple operation.
With our balance machine
A greatest dimension: φ 1800
Full length: 4,500mm
Gross weight: we can revise the work to 1 kg – 3,000 kg.

Welding of hardening agent ,thermal spray repair

Welding of hardening agent , spray repair [repair summary]
A purpose of the welding of hardening agent is that the formation (repair) does welding metal superior in wear resistance by welding in the required part of the abrasion of various industrial equipment-resistant.
An economic reason of the quantity of abrasion,basically the worn parts need exchange or repair it is the present conditions that repair it by welding when there is few it, and often re-use.
We heat materials to use for coating and melt, and the spray is a surface treatment technology to blow the surface of the material to intend for, and to form the coating layer (= film).

Parts measurement

Parts measurement [repair summary]
The parts which measured a 10μ mm unit using the metering equipment such as a micrometer and the cylinder gauge in a fit department of an axis and the hole, If it came off from a permission level, will repair or produce parts. we submit the dimensions measurement result to a customer with a report.

Examination for PT

Examination for PT [repair summary]
Inspection to confirm the yes or no of a minute crack (crack) that the parts appearance does not show by the naked eye. We perform it using the special solvent which a color remains only for a crack.
We carry out inspection with the gears of the axis and reduction gear of the centrifuge.

Getting out core adjustment, confirmation

Getting out core adjustment, confirmation [repair summary]
When a core is out of order according to the main body outer diameter, in the case of a particularly high-speed rotary machine (centrifuge), we can be connected for vibration and the machine damage during machine driving.
We perform getting out core adjustment so that a core touch becomes less than 50μ mm in us.

Various designs, production

When we suggest the maintenance method of damage parts, we explain it after having made a drawing. The production reaches not to mention the repair of maker parts in us, too.
Therefore it is early and can sometimes offer a better product cheaply than we purchase replacement parts from the maker.
The making reaches in specialized subcontractor and us every parts.

3 Shipment from site to our workshop
Please make an arrangement to ship the machine by yourself.
In domestic transportation and customs clearance will be handle in our company.
We carry out a machine from designation places

4 Resolution check
We disintegrate and wash a machine and check the abrasion degree of each part, the damage situation. we appoint a cause of the malfunction (we perform the appearance cleaning before resolution as needed).

5 Examination of all seeds
Examination for fit part.
→Specifically, look at parts measurement, an examination for PT.

8 Damage parts repair and production
We perform the repair of damaged parts and produce new parts. On the occasion of work, we make a detailed drawing in an office and can go ahead while confirming it one by one.

9 Welding/thermal Spray repair
In the case of the maintenance of the centrifugal machine, perform it as needed. After removing a defect part, and having repaired it in hard material, then finaly polish up the worn part by manual labor.
