1、冷冻水泵

1. Frozen water pump

在冷冻水环路中驱动水进行循环流动的装置。空调房间内的末端需要冷水机组提供的冷水,但是冷冻水由于阻力的限制不会自然流动,这就需要水泵驱动冷冻水进行循环以达到换热的目的。

A device that drives water to circulate in a frozen water loop. The end of the air-conditioned room needs the cold water provided by the chiller, but the chilled water will not flow naturally due to the limitation of the resistance. This requires the pump to drive the chilled water to circulate to achieve the purpose of heat transfer.

2、冷却水泵

2. Cooling water pump

在冷却水环路中驱动水进行循环流动的装置。我们知道,冷却水在进入冷水机组后带走制冷剂一部分热量,而后流向冷却塔将这部分热量释放掉。冷却水泵就是负责驱动冷却水在机组与冷却塔这个闭合环路中进行循环。

A device that drives water to circulate in a cooling water loop. We know that the cooling water takes away a part of the heat from the refrigerant after entering the chiller, and then flows to the cooling tower to release this part of the heat. The cooling water pump is responsible for driving cooling water to circulate in the closed loop of the unit and the cooling tower.

3、补水泵

3, water replenishment pump

空调补水所用装置,负责将处理后的软化水打入系统中。外形同上水泵。

The equipment used for the water supply of the air conditioner is responsible for the softening of the treated water into the system. The shape of the same water pump.

常用的水泵有卧式离心泵和立式离心泵,它们都可以用在冷冻水系统,冷却水系统和补水系统中。对于机房面积大的地方可以用卧式离心泵,对于机房面积较小的地方可以考虑使用立式离心泵。

Commonly used pumps are horizontal centrifugal pumps and vertical centrifugal pumps, which can be used in frozen water systems, cooling water systems and water replenishment systems. The horizontal centrifugal pump can be used for the large area of the machine room, and the vertical centrifugal pump can be considered for the small area of the machine room.

水泵并联运行时,流量有所衰减;当并联台数超过3台时,衰减尤为厉害。建议:

When the pump runs in parallel, the flow rate is attenuated; when the number of parallel lines exceeds 3, the attenuation is particularly severe. Suggestion:

1、选用多台水泵时,要考虑流量的衰减,一般附加5%~10%的余量。

1. When a number of pumps are selected, the attenuation of the flow is considered, and the allowance for 5% to 10% is generally added.

2、水泵并联不宜超过3台,即进行制冷主机选择时也不宜超过三台。

2. It is not suitable for more than 3 pumps in parallel, that is, it is not suitable for more than three units to choose the main engine.

3、大中型工程应分别设置冷,热水循环泵。

3. Cold and hot water circulation pumps should be set up for large and medium-sized projects.

以上就是小编为您讲解的有关知识,我们拥有严谨的工作态度,熟练的工作技能,将确保任务准确、高效的完成。

The above is the knowledge that Xiao Bian tells you. We have strict working attitude and skilled working skills. We will ensure that tasks are done accurately and efficiently.
