Frequently Asked Questions (FAQ): PGH Series

This FAQ covers general questions about the PGH series, which are commonly known as high-purity hydrogen generators used primarily in laboratory settings like Gas Chromatography (GC).

Q1: What is a PGH Series Hydrogen Generator?

A PGH series instrument is an electrically powered generator that produces high-purity hydrogen gas through the electrolysis of water. It typically consists of an electrolysis cell, a power supply, pressure control systems, and drying/purification modules to ensure gas quality.

Q2: What are the key technical specifications for a typical PGH unit (e.g., PGH-300)?

While specifications can vary by model, a common reference point is the PGH-300 model:

• Output Purity: ≥ 99.999% (relative oxygen content)

• Output Flow Rate: 0 - 300 ml/min (or as per specific model)

• Output Pressure: 0.4 MPa (approximately 58 psi). Custom pressures can often be requested.

• Power Supply: 220V, 50Hz

• Max Power: 150W

• Operating Environment: Temperature 0-40°C, relative humidity <85%, free from excessive dust and corrosive gases.

3. What type of hydraulic oil is suitable for PGH Rexroth Gear Pumps?

It is recommended to use hydraulic oil that meets ISO VG 46 or ISO VG 68 specifications. The oil should have good anti-wear and anti-oxidation properties, and the oil temperature during operation should be controlled between -10°C and 80°C to avoid affecting pump performance.

4. How often should maintenance be performed on PGH Rexroth Gear Pumps?

For general industrial applications, routine inspection (checking oil level, temperature, and leakage) should be conducted monthly; oil change and filter replacement are recommended every 6 months or after 2000 hours of operation; a comprehensive disassembly and inspection of the pump should be carried out every 2-3 years.
