About Dead Weight type Oil Water Constant Pressure System

Dead Weight type Oil Water Constant Pressure System

This device is used to maintain cell pressure constant for a long duration and the system can be used in place of convensional constant pressure system using mercury posts where certain minimum heights are required. Problems like deairiation of pump, leakage of mercury etc. are eleminated in this system. This unit is smaller in volume and can be used in mobile laboratory also. This can maintain pressure in the cell upto 20 kg/cm.sq. Pressure is maintained constant in the system by a balancing calibrated weights on a spindle against a column of oil, operating under constant feedback.

Salient Features Construction

The system consists of an oil pump continuosly driven by an eletric motor during the test period. The internal components are housed in a strong compact housing. The piston on which weights are kept rotates with minimum friction. A transparent Oil Water vessel is provided on transmit pressure to the cell. A hand pump provided facilitates priming and to maintain constant pressure during power failure.

Complete Accessories and Low Maintenance

Supplied with a comprehensive accessories kitincluding a filling bottle, spanner, and spare partsthe system simplifies both setup and routine maintenance. Its construction and design allow for easy cleaning, reducing downtime and ensuring ongoing laboratory efficiency.

FAQs of Dead Weight type Oil Water Constant Pressure System:

Q: How does the Dead Weight Type Oil Water Pressure System operate without external power?

A: This system functions through manual operation; users apply the included stainless steel weights to the pressure cylinder, generating precise pressure readings without the need for electricity or external power. The anti-vibration feet enhance stability during measurements.

Q: What is the recommended cleaning and maintenance process for this equipment?

A: Routine maintenance involves wiping down surfaces with a clean, dry cloth and ensuring the pressure cylinder and piston are free from debris. The included spanner and spares kit facilitate minor adjustments and part replacements, keeping the unit in optimal condition.

Q: When should I consider calibrating my laboratory pressure equipment with a dead weight tester like this?

A: Calibration using the dead weight system is recommended before critical experiments, periodically following your laboratory schedule, and after any incident that may affect gauge accuracy. This ensures ongoing precision in pressure measurements.

Q: Where can this dead weight pressure system be effectively utilized?

A: Its robust, manual design and wide measurement range make it ideal for laboratory environments, calibration facilities, and educational institutions where high accuracy and no dependence on electric power are required.

Q: What are the benefits of using oil or water as the pressure media in this system?

A: Both oil and water offer stability and compatibility with a variety of laboratory instruments. Choosing between them allows flexibility based on your testing needs and the nature of the devices being calibrated.

Q: How does the anti-vibration base improve the calibration process?

A: The anti-vibration feet minimize external movements or shocks, ensuring that weight application and pressure readings remain steady and accurate throughout the procedure.
