混流泵型號說明A鹽山混流泵型號說明150HW-8

正是這個原因，所以軸流泵的出水管上并不安裝閘閥。兩種水泵的效率與流量間的關系，其變化規律也不相同。離心泵的效率在流量變化時，其變化較小。也就是說，流量在較大的范圍內改變時，仍能保持較高的效率。由于離心泵高效率范圍較寬，因此水泵在運行中可以調節流量的揚程。但軸流泵則相反，流量稍有改變，效率變化較大。因此水泵在運行中不宜調節流量和揚程。水泵轉速改變時，流量與揚程、功率、效率的關系。水泵的管路及附件水泵為了完成抽水工作，不僅必須配備動務機，而且還要配備管路及其附件。管路的種類規格較多，附件也較多。以離心泵抽水站與套的管路及其附件為例，有底閥、濾閥、進水管、彎管、真空表、壓力表、出水管、逆止閥、閘閥及相應的連接法蘭、墊片、螺釘、螺母等。

二.結構和作用

混流泵型號說明A鹽山混流泵型號說明150HW-8

The materials for the Water Guide pipe, the pump body and the pump cover are cast iron. There are infiltrating grooves on the inner surface of the rubber guide bearing near the wheel, and the guide bearing is mounted directly in the housing of the pump body, which can be replaced on site after wear. The rolling bearings contained in the pump cover are two single-row phase ball bearings. The main factory producing guanting is Fujian Youxi guanting factory. (Ix) Manual pumping of labor-driven piston pumps, diaphragm pumps and screw pumps and other water extraction tools, collectively referred to as manual pumps. Manual pumps are divided into shallow well dynamic pumps and deep wells manual pumps. The flow rate of shallow well piston pump is 0.34~4.214 cubic meter/time, adapt to the suction process 2~7 meters. The flow rate of the deep well piston pump is 0.056~0.601 cubic meters/When the head is 15~40 m. The flow rate of the diaphragm pump is 0.8~6.01 cubic meters/when the flow rate of the screw pump is 0.056~0.671 cubic meter/time. (10) The pump shell of the pump is generally cast iron, it is easy to crack under the action of mechanical force or thermal stress.1.HW pump mainly has pump cover, impeller, pump body, pump shaft, bushing, and bearing body and other major components. The pump cover is connected with the pump body and the inlet pipe respectively. 2. There should be an appropriate gap between the pump cover plane and the impeller plane. The gap is too small will produce friction, the gap is too large, will lead to the pump body pressure water a large number of reflux, is the pump efficiency reduction. The suitable gap used in practice is 0.3-0.7mm, and the gap can be adjusted by adding and subtracting the thickness of the paper pad.

3. The shaft is applied to protect the pump shaft and should be replaced in time after wear.

1. Screw holes at the upper end of the pump body, used for filling water diversion or connecting vacuum pump pumping gas to divert water. 

2. In order to expand the scope of application of the pump to meet the different needs of users, can cut the outer diameter of the impeller or exchange different performance of the impeller.
