單螺桿泵的工作原理特點(diǎn)及用途
The working principle of single-screw pump characteristics and uses of
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(gè)通常用彈性材料制造的具有雙關(guān)螺旋的定子，當(dāng)轉(zhuǎn)子在定于型腔內(nèi)繞定子的軸線作行星回轉(zhuǎn)時(shí)，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。
Single-screw pump is a kind of eccentric rotation within the gear volume pumps, pump the main components: a single-head screw of the rotor and an elastic material is usually manufactured with a pun spiral stator, when the rotor cavity around the scheduled planetary rotation axis for the stator when the stator formed between the closed switch on the wrist produce displacement along the rotor spiral; so will be a continuous medium, the average rate, the volume and the constant pressure from the suction sent out the end, based on this pieces of properties, single-screw pump is particularly suitable for the work of the following conditions.
輸送高粘度介質(zhì)：根據(jù)泵的大小不同可以輸送粘度從37000-200000厘泊的介質(zhì)。
Transport high viscosity medium: According to the pumps of different sizes and can transfer from 37000-200000 cps viscosity of the medium.
含有顆�；蚶w維的介質(zhì)：顆粒直徑可以這30mm（不超過轉(zhuǎn)子偏心距）。纖維長可以350mm（相當(dāng)0.4位轉(zhuǎn)子的螺距）。其含量一般可達(dá)介質(zhì)窖的40%，若介質(zhì)中的固體物為細(xì)微之粉沫狀時(shí)，高含量可達(dá)60%或更高也能輸送。要求輸送壓力穩(wěn)定，介質(zhì)固有結(jié)構(gòu)不愛破壞時(shí)，選用單螺桿泵輸送為理想。
Containing particles or fiber media: the particle diameter can be 30mm (not to exceed rotor eccentricity). Fiber length can be 350mm (rather 0.4 rotor pitch). Its content usually ranging from 40% of medium pits, if the medium solids of the powder for subtle shape, the highest content of up to 60% or higher can also transfer. Requires delivery of the pressure stability, and media do not like to destroy the existing structure, the selection of a single screw conveyor is ideal. |
