排污泵选型注意事项
排污泵选型注意事项
Selection of pollutant discharge pump
流量:排污泵的流量应按排水秒流量选定(计量单位:L/s);当有排水量调节时,可按排水最大小时流量选定(计量单位:m³/h)。
Flow: the discharge of the sewage pump should be selected by the discharge of the drain second. When the displacement is adjusted, it can be selected by the maximum flow rate of water discharge (metering units: m cubed/h).
扬程:排污泵的扬程按照提升高度,计算管道损失后确定。 如需要输送的介质是一些含有一定固体介质(如泥沙)的混合液体,这个问题使得排污泵在电机承载能力、轴承布置、泵体密封等方面的要求比一般的水泵要高,一般来说要选择自吸排污泵或潜水排污泵。在选型和订货时,一定要了解清楚你所选择排污泵的密封性和承载能力是否合适。
Lift: the head of the sewage pump is determined after the loss of the pipe. For conveying medium are some certain solid medium, such as the sediment content of mixed liquid, the question makes sewage pump in the motor bearing capacity, bearing arrangement, meet the requirements of the pump body seal to be higher than the average pump, generally choose self-priming sewage pump or diving sewage pump. When selecting and ordering, it is important to know whether the sealing and carrying capacity of the sewage pump is suitable.
在建筑物内使用的排污泵,有潜水排污泵、液下排水泵、立式污水泵和卧式污水泵等。而立式排污泵和卧式排污泵要求设置隔震基础,要占用一定的场地空间,故在建筑中较少使用。
The discharge pump that is used in the building, the discharge pump, the drainage pump, the vertical sewage pump and the horizontal sewage pump. And the vertical discharge pump and the horizontal discharge pump require the setting of the vibration isolation foundation, which should take up the space of the space, so it is less used in the building.
在建筑物内,场地较小,排水量不大的话,可优先选用潜水排污泵和液下排污泵。其中液下排污泵一般可以在比较重要场所使用,它的整体结构紧凑、体积小、噪声小、移动方便,安装简单。节能效果显著,检修方便,无需建泵房,潜入水中即可,大大减少工程造价。
In the building, the site is small, the displacement of water is small, and the discharge pump and the discharge pump are preferred. The liquid discharge pump can be used in more important places, its overall structure is compact, small volume, small noise, easy to move and easy to install. The energy saving effect is remarkable, the maintenance is convenient, no need to build the pump room, can dive into the water, greatly reduce the project cost.
公共建筑设施内应按照每个排水集水池为单元,设置一台备用水泵,平时宜交互运行,以减少泵的长时间负荷运作,提高使用寿命。
Public facilities should be set according to each drainage pool as a unit, set up a backup pumps, at ordinary times should be interactive operation, to reduce the long time load operation of the pump, improve the service life.
当抽取带有较大介质的污废水时,不同集水池内的潜水排污泵出水管不应合并排出【滤到潜水排污泵提升含有大块杂物时】,潜水排污泵最宜带有粉碎装置。当提升含较多纤维物污水时,可采用带切割装置或者大通道潜水排污泵。
When extracting polluted wastewater with large medium, different collecting basin in the diving sewage pump outlet pipe should not be combined discharge the filter to the diving sewage pump ascending contain large debris 】, diving sewage pump most appropriate with a crushing device. When raising more fiber, use a cutting device or a large channel diving pump.
