Description
Technical field
The utility model relates to a kind of air structure of voltage regulation applied to water-cooling system and using its water-cooling system, belong to
In water-cooling system technical field.
Background technique
In closed circulation water-cooling system, if water circulating pump inlet generates negative pressure, it may occur that the phenomenon that medium gasifies,
The heat transfer effect of water system is influenced, will lead to the impeller failure of water pump under serious conditions, therefore, main circulation pump inlet is kept to deposit
It is one of the necessary condition for guaranteeing water system reliability service in reasonable positive pressure.General water-cooling system using nitrogen stabilization pressure,
3 kinds of voltage regulation ways such as high water tank pressure stabilizing or capsule-type expansion drum pressure stabilizing.
Wherein, high water tank by hydraulic pressure that the difference in height of water level in water tank and other extreme higher positions of water system generates come
A stable positive pressure value is provided to main circulation pump entrance.It is influenced by building height, the main circulation pump entrance pressure stabilizing value provided
Adjustable extent is less than normal, and main circulation pump inlet pressure is lower.Furthermore scene also need design high water tank two water pipe branches and its
Component, therefore increase design and field erected workload.
Nitrogen stabilization pressure is then the nitrogen cylinder that high pure nitrogen is full of by one, gives a suitable pressure value in expansion drum,
Expansion drum export pipeline accesses main circulation pump entrance pipe, thus reach the loine pressure of stable water system main circulation pump entrance
Purpose avoids main circulation pump entrance from generating negative pressure, to guarantee that this water system is reliably run.The pressure that nitrogen stabilization pressure provides
It is higher, it is relatively high to the air-tightness requirement of pipeline, and system has certain consumption to nitrogen, nitrogen can be consumed gradually, be needed
Nitrogen cylinder is regularly replaced, increases the workload of repair and maintenance, and nitrogen cylinder belongs to pressure vessel, transport limitation is more.
Capsule-type expansion drum is by gas (usually nitrogen or air) and system moisture using 1 capsule shape air bag at two
Partial hermetically sealed container.Expansion drum is used to absorb the medium of expanded by heating, realizes the dynamic equilibrium of system pressure.Expansion drum peace
It is attached in the pressure medium system more slightly higher than its gas chamber precharge of gas pressure, understands some working media by interface and enter gas
It is intracapsular, until reaching new pressure balance.Conversely, pressure medium is lower than gas chamber gas pressure in system when system pressure reduces,
Working media in air bag can be extruded, and added in system, increased system pressure, until system working medium pressure and gas
Room gas pressure is equal.Expansion drum voltage regulation way has its limitation to system media swell increment, and expansion drum pressure stabilizing may also go out
The problems such as existing gas leakage, needs to configure corresponding pump-up device in engineering, needs periodically to be safeguarded.
Therefore, studying a kind of has that long service life, installation maintenance are simple, land occupation size is small, successive projects put into operation
The structure of voltage regulation of the small water-cooling system of maintenance workload is of great significance.
