2.均勻并且薄的橡膠層在設(shè)備運行過程中抗變形能力好，因而等壁厚定子螺桿泵單級承受的壓力高，在相同工況運行下，可以減少泵的級別和定轉(zhuǎn)子之前過盈的配合量，同時運轉(zhuǎn)扭矩和系統(tǒng)于常規(guī)泵型，從而提高泵的使用性能。

2. Uniform and thin rubber layer is with good anti-deforming

capability in the operation process of the equipment, so screw pump of the

stator with equal wall thickness bears high pressure based on1 single stage

which can reduce pump level and previous excess suitable quantity of stator and

rotor in case of operation under the same operating condition and operating

torque and system efficiency are higher than those of conventional pump to

improve pump usability.

3.等壁厚定子橡膠溶脹、溫脹均勻，能較好的保證泵的型線，泵的密封性能好，使用運轉(zhuǎn)時具有良好的力學(xué)性能，有利于長時間持續(xù)泵的，從而延長泵的使用周期。

3. Rubber of stator with equal wall thickness is with even

swelling and thermal expansion which can well ensure molded lines of the pump.

The pump is with good sealing property as well as good mechanical property at

the moment of use and operation, making for continuous high efficiency of the

pump for a long time to prolong service cycle of the pump.

液下污水泵葉輪采用多種形式，主要是旋流：大大提高了污垢的通過能力，能有效地通過泵徑5倍的纖維材料，直徑約為50%的固體顆粒;流道類型：其抗繞、無堵塞性能較好，在幾種無堵塞葉輪中，泵，耐磨性好。螺旋離心：該葉輪無堵塞，適用于含有顆粒和纖維材料的液體，對運輸材料的破壞性較小。開或半開：葉輪磨損間隙增大，導(dǎo)致泵性能下降。

a.結(jié)構(gòu)簡單,使用可靠,維護方便。

　　b.電機功率、水泵揚程及排水量的范圍寬

　　c.電機耐水,不用擔(dān)心水進入電機內(nèi)部損壞繞組和絕緣結(jié)構(gòu)。即使在不正常的情況下,電機內(nèi)部的水滲漏到井內(nèi),也不會污染水質(zhì);不會傷害人備的健康和農(nóng)作物,應(yīng)用不受限制。

　　干式和充油式潛水電機,對水密封的要求高。一旦水密封出故障,水進入電機內(nèi)部,繞組絕緣就會遭到破壞,電機不能使用。充油式電機內(nèi)的油滲漏到井內(nèi),會污染水質(zhì),人畜就不能飲用,也不可用來澆灌農(nóng)作物,使用受到一定的限制。
