Starting from now, in order to enhance communication among users, a 【Daily Question】 campaign has been launched on the Mechanical Equipment Technology forum. We hope everyone will participate actively to progress and improve together! ! ! Rewards: 3 points for active participation, 10-15 points for correct answers. This question is valid for two days only; no scoring will be given after that period. The diagram below shows a siphon tank. Many of those who replied last week got it wrong – please explain the brief working process of a siphon tank. Answer: The high-temperature, high-pressure vapor discharged by the compressor is condensed into a liquid in the condenser. It first enters the siphon tank; when the liquid level in this tank reaches the overflow port, it flows into the liquid storage tank from where it is supplied to the evaporator. The liquid below the overflow port in the siphon tank flows, driven by gravity, to the compressor’s oil cooler. There, it absorbs heat from the lubricating oil and turns back into a gas, which then returns to the siphon tank through the return port. The liquid carried by the gas is separated within the siphon tank, and the dry gas, along with the compressor’s exhaust gas, enters the evaporation-type condenser where it is condensed. The condensed liquid then enters the next cycle. https://attach01.hcbbs.com/forum/201711/24/094501awc00m0y8rssc5ke.jpg https://attach01.hcbbs.com/forum/201711/24/094502zbycfffyt9fr9ydb.png ================================ High-quality promotions: Mechanical equipment——York screw compressors: maintenance procedures https://bbs.hcbbs.com/thread-1806833-1-1.html Mechanical equipment——Upgrading York Quinton control centers https://bbs.hcbbs.com/thread-1804837-1-1.html Mechanical equipment——Overhaul of GEA Grasso screw compressors https://bbs.hcbbs.com/thread-1800467-1-1.html Mechanical equipment——Disassembly and maintenance of British HOWDEN screw compressors https://bbs.hcbbs.com/thread-1832529-1-1.html Mechanical equipment——Disassembly and maintenance of Japanese MYCOM screw compressors https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1786445
A thermosyphon refrigeration cycle is equipped with a syphon (i.e., an auxiliary liquid reservoir). The condensed liquid from the condenser flows into the siphon and then splits into two paths; the main portion flows from the siphon’s overflow port into the liquid storage tank, from where it is supplied to the evaporator ； The other portion is supplied by gravity from the bottom of the siphon to the horizontal shell-and-tube oil cooler, where the oil is cooled; the high-pressure steam generated as a result of evaporation then returns to the siphon. The gas, after separation from the liquid, enters the condenser under the siphonic effect created by the compressor’s exhaust gas, thus continuing the cycle.
The purpose of installing a siphon tank is to use the condensed liquid to cool the refrigeration oil. The working principle is that the condensed liquid first enters the siphon tank, from where it is connected to the compressor oil cooler through pipes at the bottom of the tank; after absorbing heat, it is discharged into the condenser. Any excess condensed liquid is then led out from the middle of the siphon tank and sent to the liquid storage tank.
The working principle is that the liquid that has condensed first enters the siphon tank; through the pipes at the bottom of this tank, it is connected to the compressor oil cooler. After absorbing heat, it is then sent to the condenser. The excess liquid that has condensed is drawn out from the middle of the siphon tank and sent to the liquid storage tank.
