FPU Pre-Charging Unit

1.Model code

1、Code ：FPU（Pre-Charging Unit ）
2、Pressure gauges (MPa)，25（standard）10、40、60；
3、Hose (meter) =1.5m (standard)
4、Connection to bottle (G0 China, can omitted)

5、Suitcase (can Omit) K1（Charging Unit）

2.General

FPU type pre-charging tools used for bladder, piston and diaphragm type accumulator charging nitrogen pressure test and adjustment. When using, please will pneumatic tool of the air head spin in the accumulator valve, and through the air hose and nitrogen cylinder connection. If only testing or drop nitrogen pressure, air hose don't connect. Through the counterclockwise rotation core shaft open accumulator valve order to adjust pressure.

3.Structure

A complete set of pre-charging tool FPU by the following several parts: the body (bottom with a spin nut D), handle A, check valve C, pressure relief valve B, pressure gauge, air hose, all kinds of inflatable joint (A1 ~ A4 joint).

4.Operation Guide

The body of the M28 x 1.5 internal thread is used for diaphragm type accumulators inflatable. For bag type or piston accumulator aeration, as long as in the body can be connected conversion joint.

Will air joint twist to the accumulator valve, and at the same time ensure that pressure relief valve is closed, counterclockwise rotation core shaft Allen screw to open valve.

Carefully opened pressure relief valve, nitrogen into the air.

5.matters needing attention

Note: it is strictly prohibited to will oxygen or air filling the accumulator, it will lead to an explosion.

In each test or adjust accumulator inflation pressure before, please will accumulator and system disconnection and liquid emptying.

Air, nitrogen gas bottle of pressure must be high enough, in order to meet the requirements of the aeration, otherwise, need to have nitrogen charging equipment.

Need to comply with the corresponding safety regulations, must use more than 99.2% purity nitrogen.

Applications include conventional hydraulic systems, machine tools, engineering machinery and other fields. Our company has a group of experienced high-level engineers with doctoral and master's degrees in hydraulic, mechanical manufacturing, automation, and polymer materials, and has strong new product research and development capabilities. The company has a wide range of production and operation in the field of mechanical and hydraulic technology.

The accumulator products produced by Bukoma Company have a good ranking in the same industry in China. The enterprise has obtained ASME certificate. Later, we have successively obtained PED certificate, DNV certificate, CRN registration, ISO9001 certificate, pressure vessel manufacturing license and pressure vessel design license issued by General Administration of Quality Supervision, Inspection and Quarantine. The accumulator produced by our company can adapt to the use needs of different industries, and can be designed and manufactured in a positive way, and the products are exported and sold all over the world.
