Product Introduction:
Rated pressure exhausting and water charging device is one of the main equipment of air conditioning water system, which is suitable for the central air conditioning cold and hot water medium system of all kinds of ships sailing on the sea. It provides cold and hot water medium for central air conditioning system, and automatically constant pressure, exhaust and water refill for water system.
Model Description:
"C" : Marine
"DY" : automatic exhaust constant pressure water refill device
"2.0" : form, 1.5 is single cold type, 2.0 is hot and cold type.
Main components:
It is composed of cold/heat medium circulating water pump, vacuum exhaust device, water filling device, pressure expansion tank, plate heat exchanger, two-way flow control valve, pressure gauge, cut-off valve, filter, pipe and electrical control box and other equipment, all assembled on a common base.
Product features:
Marine automatic exhaust constant pressure water refill device has the functions of constant pressure, exhaust and water refill. Working principle of constant pressure, hydrating function: is the use of the expansiveness of the gas, the volume of water increases when the system temperature, system pressure, then there will be a part of the water into the bladder type constant pressure tank capsule, capsule expansion will be compressed gas tank, the pressure and the pressure of the tank until the system balance. When the volume of water in the system decreases and the system pressure decreases, the gas in the tank expands and the water pressure in the bag returns to the system. If the amount of water still cannot meet the requirements of the system, the automatic water refill device starts to fill water.
Exhaust function works: in the system including the water through the vent pipe of the gas into the vacuum in the vacuum injection pipe jet exhaust (full sealed special stainless steel tanks), is placed in the vacuum injection tube atomization nozzle, will enter the vacuum injection pipe liquid atomization (full contact with the vacuum is conducive to gas water separation); When the liquid level in the vacuum injection pipe rises to the set induction position, the equipment will start the suction pump on the supplementary pressure pipe to pump the water in the vacuum injection pipe into the system rapidly. Due to the difference in the flow rate between the exhaust pipe and the backwater pipe, the liquid level in the vacuum injection pipe will decrease rapidly. At the same time, vacuum is generated in the vacuum injection tube (the gauge connected to the vacuum tube will display pressure close to -1bar); At this time, the gas-rich water injected into the vacuum injection pipe precipitates a large amount of gas due to the pressure difference (almost all of it precipitates in the vacuum environment) and accumulates in the upper part of the vacuum injection pipe. When the liquid level drops to the position of the liquid level sensor (LSL), the pump stops working. System still keep the water in the vacuum injection pipe water injection, the upper side by side out of the gas into the vacuum injection pipe, the vacuum jet pipe in the water again, accumulate in the upper part of the vacuum injection pipe gas through the installation at the top of the one-way valve, water pump to start again, this time will deal with good water added by the water pump system, complete for the exhaust of water; Over and over again.
Product advantages:
Marine automatic exhaust constant pressure water refill device integrates the function components of constant pressure, exhaust and water refill into one body. It has the advantages of energy saving and emission reduction, convenient and simple operation, compact structure, stable performance, low energy consumption, low noise, shock resistance and swing resistance, convenient maintenance and so on. Air conditioning units are designed, manufactured and delivered according to classification society specifications (such as "CCS", "ABS", "NK", "DNV", etc.), and can be customized according to the actual needs of customers.
