FAQS about Filling the shearing machine nitrogen accumulator

How to fill a nitrogen bottle in a shearing machine?

Firstly, prepare nitrogen bottle and the nitrogen filling tool. The filling tool is normally shipped with the shearing machine. Step 2: connect the filling tool with the accumulator and the nitrogen bottle Step 3: open the valve on filling tool, then open the valve on the nitrogen bottle slowly

How to fill a nitrogen accumulator?

Here are the steps to fill the accumulator: Before you start the filling process, make sure that your nitrogen refill station is in good working condition. Check the pressure gauge and ensure that the nitrogen supply valve is open. If the nitrogen supply in your refill station is low, refill it to the recommended pressure level.

How to check the nitrogen pressure in a hydraulic accumulator?

Inspect the nitrogen pressure by accumulator nitrogen tool. If the nitrogen pressure is less than 5~6 Mpa, pls fill in. After inspection and the filling, pls follow up the oil filling procedures（5.7） CAUTION: ONLY FILL IN THE NITROGEN INSIDE THE ACCUMULATOR, OTHERS ARE STRICTLY PROHIBITTED 8.4 The maintenance of the hydraulic system...

How do you fill a nitrogen accumulator with a pressure gauge?

Attach the pressure gauge to a different source of nitrogen. Slowly open the valve to allow the pressure gauge to fill with nitrogen. Observe the pressure reading on the gauge and make sure it matches the desired pressure for your accumulator. If the pressure is too low, repeat the filling process until the desired pressure is obtained.

How to fill the oil accumulator?

To filling oil into the accumulator, it needs two persons to work together. Step 1: one person goes to back of the shearing machine. Find the valve with pressure gauge on the bottom of the accumulator. Open the valve. Step 2: one person goes to the front the machine. Find the oil filling button on the control panel.

How do I recheck my nitrogen accumulator pressure?

Here is how you can recheck the pressure: Start by turning off the nitrogen supply to avoid any accidental release. Disconnect the pressure gauge from the accumulator valve. Attach the pressure gauge to a different source of nitrogen. Slowly open the valve to allow the pressure gauge to fill with nitrogen.

The role of cold welding machine energy storage capacitor

The Stored Energy welding power supply – commonly called a Capacative Discharge Welder or CD Welder – extracts energy from the power line over a period of time and stores it in welding capacitors.

FAQS about The role of cold welding machine energy storage capacitor

How does CD welding work?

With CD welding, the main energy is stored in a capacitor arrangement. In application, that energy is discharged through a transformer creating again low voltage – high current power for welding. CD welding does differ from conventional resistance welding in a number of ways(1).

What is capacitor discharge welding?

Capacitive discharge welding, particularly for large-scale systems, is typically done using film-type capacitors. These capacitors store energy along alternating plates separated by a dielectric film. Charge is stored statically along the lengths of the plates. The basic configuration of the film capacitor is provided in Figure 1.

Can electrolytic capacitors be used in large-scale CD welding applications?

In this study, the suitability of electrolytic capacitor arrangements for use in large-scale CD welding applications was investigated. Baseline for the study was a set-up using a 1280-μF main capacitor. The application was a mild steel weld nut with three projections attached to a similar material substrate.

Do electrolytic capacitors yield identical weld performance results?

The results presented here indicate that electrolytic capacitors, configured to provide similar charge voltage and energy storage, can yield identical weld performance results. Process, mechanical strength, and metallographic results are all identical for the two capacitor arrangements.

Does a film capacitor provide a similar voltage tolerance for CD welding?

Performance was evaluated based on current range behavior and metallographic response. Conclusions from this work include: to film capacitors – An array was developed to provide similar voltage tolerance and system capacitance to a standard film variant conventionally used for CD welding.

What is capacitive discharge or CD welding?

Capacitive discharge or CD welding is a variant of resistance welding(1,2). The process differs from the conventional variants largely in the type of power supply used. Conventional systems provide some variant of alternating current to a transformer arrangement.

Micro energy storage machine

Micro-sized energy storage devices (MESDs) are power sources with small sizes, which generally have two different device architectures: (1) stacked architecture based on thin-film electrodes; (2) in-plane architecture based on micro-scale interdigitated electrodes [6].
