The advantages of Vacuum heat treatment
As briefly discussed in Principal Applications for Steam, both positive pressure steam and vacuum steam can be used in heating processes. The following article will discuss the properties of vacuum steam and its advantages over heating with hot water. The higher the pressure, the higher the temperature of saturated steam.
What is a Vacuum Pump : Types, Advantages,and Disadvantages
Vacuum Hot Water Boiler Advantage 1. Safe and reliable: Vaccum hot water boiler adopt phase change working principle. its medium circulation system pressure below the atmospheric pressure, internal absolute pressure is 0.02 ~ 0.08 MPa, so that it can't explode. 2.
Vacuum pumps are used to improve the efficiency of steam heating systems in many ways. The most important consideration is the rapid and efficient removal of air. Air actually acts as an insulation. It inhibits the flow of steam and reduces its heat transfer capabilities.
During cold weather when the boiler is always on, air removal is not much of a concern so the vacuum pump's job now is pressure reduction; allowing the system to operate with the lowest possible steam pressure. Let's say for example the system is operating @ 7 PSI steam pressure and there is no vacuum on the return lines.
Some of the advantages of a vacuum furnace A vacuum furnace is a type of furnace that can heat materials, typically metals, to very high temperatures and carry out processes such as brazing, sintering and heat treatment with high consistency and low contamination. In a vacuum furnace the product in the furnace is surrounded by a vacuum.
Vacuum heat treatment can achieve almost all heat treatment process, such as quenching, annealing, tempering, carburizing, nitriding, nitriding. For the quenching process, it can realize gas quenching, oil quenching, nitrification quenching, water quenching, etc. Compared with the traditional heat treatment, it has the following advantages: 1.
