英國GRIMM格林進口凸輪轉子泵概述：

          進口凸輪轉子泵又稱膠體泵、凸輪泵、三葉泵、萬用輸送泵等，轉子泵屬于容積泵，輸送流量可以較精確的控制也可方便地制成變量泵。此泵的轉速很低，一般在200rpm至600rpm之間，被輸送的物料被平穩(wěn)地輸出而其成份不會受到破壞。可用于輸送粘度很高的物質也可以方便地制成輸出壓力較高的品種。根據客戶管道連接方式的需要，可做成上進下出型轉子泵，根據客戶安裝方式及生產的需要，可做成移動型轉子泵，根據客戶調節(jié)轉速及流量的需要，可做成變頻調速型轉子泵。
          轉子泵依靠兩同步反向轉動的轉子(齒數為2—4)在旋轉過程中于進口處產生吸力(真空度)，從而吸入所要輸送的物料。兩轉子將轉子室分隔成幾個小空間，并按a→b→c→d的次序運轉。運轉至位置a時，只有一室中充滿介質；到位置b時，B室中封閉了部分介質；到位置C時，A室中也封閉了介質；到位置d時，A室B室與二室相通，介質即被輸送至出料口。如此循環(huán)往復，介質(物料)即被源源不斷輸送出去。
          轉子泵采用聯(lián)軸整體組裝，使體積變小（長度可以減短100-250mm），減少占地面積，結構緊湊，外包不銹鋼，鏡面拋光，外形美觀，檔次高，避免原來涂膏刷漆的脫落。性能優(yōu)化：采用聯(lián)軸整體組裝，減少彈性聯(lián)軸器功率消耗，噪音及磨損更換而提高工作效率，得到了zui高的效率，zui小的內部滑動和更長的使用壽命。
不同形狀的轉子具有不同的效果，具體分為以下幾大類：
一葉轉子：適用于輸送含有大顆粒物料的介質，對大顆粒物料的破碎率較低，但其脈動大，壓力低，容積量小，很少使用。
二葉轉子：適用于輸送含有中小顆粒物料的介質，對中小顆粒物料的破碎率相對較低，略有脈動，容積量小于三葉轉子。
三葉轉子：通用的轉子類型，容積量大于其他類型的轉子，各種性能指標優(yōu)于一葉，二葉轉子，但其在輸送物料的過程中對顆粒物料有一定的破碎率。
傳動的選擇：
1、電機＋定整比減速器：這樣的傳動方式簡單，轉子的轉速恒定，也就是決定了流量的不可調性。
2、電機＋機械摩擦式無級變速器：這種變速器的變速靠手動調節(jié)來實現，其特點是安全可靠，扭距大，流量無極可調，缺點是非自動調節(jié)，較麻煩，調速在運轉過程中進行，不得在停機狀態(tài)下調速，其使用維護參照制造商的使用說明書。
3、變頻電機＋變頻器：這種方式可實現轉速的自動調節(jié)，亦即實現了流量的無級調速。其優(yōu)點是自動化程度高，低速扭距較大，缺點是變頻器的價格較高，其使用維護參照制造商的使用說明書。

UK GRIMM Inlet cam rotor pump summary:

         imported cam rotor pump, also known as colloid pumps, cam pumps, three leaf pumps, pumps and so on, the rotor pump is a displacement pump, the flow can be more accurate control, but also can be easily made variable pump. The speed of the pump is very low, generally between 200rpm to 600rpm, the transported material is smoothly output, and its components will not be damaged. The utility model can be used for conveying materials with high viscosity, and can also conveniently produce varieties with higher output pressure. According to the needs of customers pipe connection, can make progress under the rotor pump, according to the needs of customers installation and production, can be made into a mobile type rotor pump, according to the needs of customers and the speed of flow regulation, can be made into a variable speed rotary pump.

        The rotor pump relies on two simultaneous, reverse rotating rotors (2 to 4 teeth) to generate suction (vacuum) at the inlet during the rotation so as to absorb the material to be conveyed. The two rotor divides the rotor chamber into a few small spaces and runs in the order of a, B, D, C. To the position of a running, only one room filled with medium; to position B, B encloses part of the medium; to the position of C, A in the room also closed to the media; the position of D, A room B chamber and the two chamber, the medium is transported to the discharge port. In this way, the medium (material) is transported continuously.

        The rotor pump adopts the whole shaft assembly, so that smaller size (the length can be shortened 100-250mm), to reduce the area, compact structure, coated with stainless steel, mirror polished, beautiful appearance, high grade, avoid dropping original paste paint. Performance Optimization: the overall assembly of the axle reduces the power consumption, noise and wear and tear of the elastic couplings, improves efficiency, achieves the highest efficiency, minimum internal sliding and longer service life.

Rotors of different shapes have different effects, and are divided into the following categories:

Blade rotor: suitable for conveying medium containing large particles of material, the crushing rate of large particles of material is low, but its large fluctuations, low pressure, small volume, rarely used.

Two blade rotor: suitable for conveying medium and small particles of materials, the crushing rate of small and medium-sized materials is relatively low, slightly pulsating, less volume than the trefoil rotor.

Three blade rotor: General rotor type, the volume is greater than other types of rotor, various performance indicators better than a blade, two blade rotor, but in the process of conveying materials, the particle material has a certain rate of fragmentation.

Transmission options:

1.Motor + fixed ratio reducer: this way of transmission is simple, the rotor speed constant, that is to determine the flow of non adjustability.

2.Motor + mechanical friction CVT: the transmission speed by manual adjustment to achieve, it is safe and reliable, large torque, flow rate is adjustable, drawback of non automatic adjustment, more trouble, control in the process of operation, not in the shutdown state governor, referring to the use of maintenance the manufacturer's instructions.

3.Frequency conversion motor + frequency converter: this method can realize the automatic adjustment of speed, that is to realize the stepless speed regulation of flow. The utility model has the advantages of high degree of automation, low speed large torque converter, disadvantage is the higher prices, the use of maintenance according to the manufacturer's instructions.
