地下车库出入口使用无震动防滑坡道的优点

供热系统压力较高时,采用水箱不能保证系统所需的压力,此时,应当采用补给水泵定压方式。这种定压方式在苏联热水供热系统中被普遍应用。补给水泵定压有连续补水定压和连续补水定压两种方式。 此环亚ag平台定压方式的安装由补给水箱,补给水泵,压力调理器等组成。当系统运转正常时,经过压力调理器调理使补给水泵连续补水并使之与系统的走漏量相顺应,从而维持系统压力的稳定。当循环水泵停运时,能够关闭压力调理器前的截止阀。补给水泵仍连续补水以维持系统所需的静压。
When the pressure of heating system is high, the water tank can not guarantee the pressure required by the system. At this time, the way of constant pressure of supply pump should be adopted. This constant pressure method is widely used in the heating system of hot water stove in the Soviet Union. There are two ways of constant pressure of supply pump: continuous water supply and constant pressure of continuous water supply. The installation of the constant pressure mode of the biomass hot blast stove consists of a supply water tank, a supply water pump, a pressure regulator, etc. When the system is in normal operation, the pressure regulator is used to make the supply pump continuously replenish water and make it conform to the leakage of the system, so as to maintain the stability of the system pressure. When the circulating pump is out of operation, the shutoff valve in front of the pressure regulator can be closed. The replenishment pump continues to replenish water to maintain the static pressure required by the system. 这种定压方式无需收缩水箱,因此设备费用低廉,此外,补给水泵又补水又定压,水泵功率不大,运转费用也很小。因而,这种方式在我国热水供热系统中应用相当普遍。
This constant pressure method does not need to shrink the water tank, so the cost of equipment is low. In addition, the supply pump is also constant pressure, the pump power is not large, and the operation cost is small. Therefore, this method is widely used in China's hot water heating system.

养殖专用厂家表示为避免此时缺水汽化,系统中采用了压力上水辅助型安装,当循环水泵运转时,由于上水辅助安装,循环水不会倒灌到压力上升系统中去。当忽然停电而使循环水泵,补给水泵停运时,压力上水系统立刻投入运转,止回阀被自动翻开,压力水将流经热水并从集气罐排出,从而防止了炉室余热惹起锅水汽化。
The great defect of this constant pressure method is that if the power system is suddenly cut off, the supply pump will lose its constant pressure function. In order to avoid the water shortage and vaporization of the hot blast stove at this time, the manufacturer of the special boiler for aquaculture said that the auxiliary installation of pressure water was adopted in the system. When the circulating water pump was running, the circulating water would not be poured back into the pressure rising system because of the auxiliary installation of the water supply. When the circulating water pump and the supply water pump are shut down due to a sudden power failure, the pressure water supply system is put into operation immediately, the check valve is automatically opened, and the pressure water will flow through the hot air stove and be discharged from the gas collecting tank, thus preventing the boiler water vaporization caused by the residual heat of the furnace chamber.

与此同时的操作是应该关闭供,回热水管总阀,使得热源和热网隔绝开来。环亚ag平台补给水泵连续补水定压由电接点压力表控制来完成,循环水泵入口压力能够维持在一定范围内,当压力低于这个范围时,电接点压力表动作并接通补给水泵电动机电路,补给水泵运转,补水,热水循环泵入口压力升高并超越一定范围时,热水热风炉的压力表就是切断补给水泵电源,是补给水泵停运。
At the same time, the operation is to close the main valve of the supply and return water pipe so as to isolate the heat source from the heat network. When the pressure is lower than this range, the electric contact pressure gauge acts and connects the motor circuit of the supply water pump. When the supply water pump runs, the supply water pump runs, the supply water is supplied, and the inlet pressure of the hot water circulating pump rises and exceeds a certain range, the hot water hot air stove's inlet pressure can be controlled by the electric contact pressure gauge. Pressure gauge is to cut off the supply pump power supply, is the supply pump shutdown.

如此往复动作,补给水泵连续补水,并维持系统压力在一定范围内动摇,这样系统定压方式,由于连续补水,就比连续补水俭省电能,但是其调理和定压质量比连续补水方式要差,还有压力动摇大,压力表触点动作频繁易于损坏等缺陷。
Such reciprocating action, the supply pump continuously replenish water, and maintain the system pressure to shake in a certain range, so that the system constant pressure mode, because of continuous replenishment of water, is more economical than continuous replenishment of electricity, but its conditioning and pressure quality is worse than continuous replenishment mode, there are pressure fluctuation, pressure gauge contact action frequent and easy to damage and other defects.
