空心轉(zhuǎn)子優(yōu)勢：

Advantages of hollow rotor:

1.空心轉(zhuǎn)子重量減輕后，與常規(guī)轉(zhuǎn)子的軸向扭力減弱，啟動扭矩降低，減速電機選型偏小，客戶使用成本大大降低，達到環(huán)保節(jié)能效果。

1. After the weight of the hollow rotor decreases, the axial

torsion of conventional rotor will recede, break-out torque will lower, gear

motor type will be relatively small, as well as customer's use cost will

greatly lower with effect of environmental protection and energy saving

obtained.

2.因摩擦力與重量有密切關(guān)聯(lián)，因此與同等實心轉(zhuǎn)子對比，重量減輕后，泵在運行過程中轉(zhuǎn)子摩擦力減弱，使用壽命同比增大。

2. Because the force of friction is closely related to

weight, the force of friction of the rotor lowers and service life increases on

a year-on-year basis in the operation process of the pump after the weight1

decreases in comparison to the equivalent solid rotor.

3.泵在快速啟動和高速運轉(zhuǎn)過程中的震動明顯減小。

3. Pump vibration iously decreases in the process of quick

start and high-speed operation.

4.設(shè)備運行過程中，噪音分唄大幅度降低，不會有噪音污染。

4. In the operation process of the equipment, noise decibel

is greatly lowered without noise pollution.

單螺桿泵的工作原理、特點及選用方法   ●泵的工作原理    單螺桿泵是一種內(nèi)嚙合偏心回轉(zhuǎn)的容積泵，泵的主要構(gòu)件：一根單頭螺旋的轉(zhuǎn)子和一個通常用彈性材料制造的具有雙關(guān)螺旋的定子，當轉(zhuǎn)子在定于型腔內(nèi)繞定子的軸線作行星回轉(zhuǎn)時，轉(zhuǎn)定子之間形成的密閉腕就沿轉(zhuǎn)子螺線產(chǎn)生位移；因此就將介質(zhì)連續(xù)地，均速地、而且容積恒定地從吸入口送到壓出端，基于這件特性，單螺桿泵特別適合于下列工況的工作。



單螺桿泵的選型要點1.單螺桿泵的壓力確定： 單螺桿泵輸出壓力是根據(jù)襯套級數(shù)即襯套的導程數(shù)來確定： 1級：工作壓力為0.6 MPa； 2級：工作壓力為1.2 MPa； 4級：工作壓力為2.4 MPa； 由于輸送介質(zhì)情況不同，3qgb螺桿泵對于含有嚴重磨損性的介質(zhì)，請參照表一選擇襯套級數(shù)。表一：根據(jù)介質(zhì)的磨損性選擇襯套級數(shù) 磨損性 一級 二級
