進口雙螺桿泵 進口單螺桿泵

德國KAYSEN凱森進口雙螺桿泵概述

進口雙螺桿泵是由主從動軸上相互嚙合的螺旋套和泵體或襯套間形成一個容積恒定的密封腔室，介質(zhì)隨螺桿軸的轉(zhuǎn)動分別被送到泵體中間，兩者匯合在一起，最終送達泵的出口，從而實現(xiàn)泵輸送的目的。

雙螺桿泵有密封式和不密封式兩種類型，按介質(zhì)從一端還是 從兩端進入嚙合空間，雙螺桿又被分為雙吸式和單吸式兩種結(jié)構(gòu)。

雙螺桿泵是外嚙合的螺桿泵，它利用相互嚙合，互不接觸的兩根螺桿來抽送液體。

雙螺桿泵為一種雙吸式非密閉的雙螺桿泵。一端伸出泵外的主動螺桿由原動機驅(qū)動。主動螺桿與從動螺桿具有不同旋向的螺紋。螺桿與泵體緊密貼合。從動螺桿是通過同步齒輪由主動螺桿帶動的。

雙螺桿泵作為一種容積式泵，泵內(nèi)吸入室應(yīng)與排出室嚴(yán)密地隔開。因此，泵體與螺桿外圓表面及螺桿與螺桿間隙應(yīng)盡可能小些。同時螺桿與泵體、螺桿與螺桿間又相互形成密封腔，保證密閉，否則就可能有液體從間隙中倒流回去。

雙螺桿泵可分為內(nèi)置軸承和外置軸承兩種形式。在內(nèi)置軸承的結(jié)構(gòu)型式中軸承由輸送物進行潤滑。外置軸承結(jié)構(gòu)的雙螺桿泵工作腔同軸承是分開的。由于這種泵的結(jié)構(gòu)和螺桿間存在的側(cè)間隙，它可以輸送非潤滑性介質(zhì)。此外，調(diào)整同步齒輪使得螺桿不接觸，同時將輸出扭矩的一半傳給從動螺桿。正如所有螺桿泵一樣，外置軸承式雙螺桿泵也有自吸能力，而且多數(shù)泵輸送元件本身都是雙吸對稱布置，可消除軸向力，也有很大的吸高。
雙螺桿泵系列產(chǎn)品分為單吸雙螺桿泵和雙吸雙螺桿泵兩大類。該系列產(chǎn)品具有特殊的螺桿型線和與之配套的特殊結(jié)構(gòu)，廣泛適用于石油、化工、冶金、鋼鐵、電力、船舶、制藥、食品、建材等各種行業(yè)，其適用介質(zhì)之多、輸送范圍之廣、應(yīng)用工況之復(fù)雜是其它泵類產(chǎn)品無法比擬的。這些特點也使得該系列泵具有潛在的使用發(fā)展前景。

主要特點：
該型泵采用雙吸式結(jié)構(gòu)，螺桿兩端處于同一壓力腔中，軸向力可以自行平衡。兩端軸承采用外裝式，單獨采用潤滑油(脂)潤滑，因而不受輸送介質(zhì)的影響。兩螺桿間用一對同步齒輪驅(qū)動，螺桿齒面間并不接觸，而留有一微小間隙，介質(zhì)中的雜質(zhì)并不能對螺桿齒面產(chǎn)生直接的磨損(除沖刷外)。 除一些小排量泵外(2W.W4.0以下)，一般在泵體上都帶有內(nèi)流式安全閥，當(dāng)排放壓力超過額定值時，有一定的保護作用。 泵體上的進出口方向有兩種，一為水平進，水平出;二為水平進，垂直向上出;用戶可根據(jù)自己需要選擇。

Germany Kaysen imported twin screw pump overview

The twin-screw pump forms a sealed chamber with a constant volume between the spiral sleeve and the pump body or the bushing which are engaged with each other on the main driven shaft, and the medium is respectively sent to the middle of the pump body with the rotation of the screw shaft, and the two are merged together. Finally, it is delivered to the outlet of the pump to achieve the purpose of pump delivery.

The twin-screw pump is available in both sealed and unsealed versions. The two screws enter the meshing space from one end or from both ends. The twin-screw is divided into two types: double suction and single suction.

The twin-screw pump is an externally engaged screw pump that uses two screws that are in mesh with each other and that are not in contact with each other to pump liquid.

The twin screw pump is a double suction non-closed twin screw pump. An active screw that extends out of the pump at one end is driven by the prime mover. The active screw and the driven screw have different directions of rotation. The screw is in close contact with the pump body. The driven screw is driven by the drive screw through the synchronizing gear.

The twin-screw pump is a positive displacement pump, and the suction chamber inside the pump should be closely spaced from the discharge chamber. Therefore, the outer surface of the pump body and the screw and the gap between the screw and the screw should be as small as possible. At the same time, the screw and the pump body, the screw and the screw form a sealed cavity between each other to ensure the sealing, otherwise the liquid may flow back from the gap.

Twin screw pumps can be divided into two types: built-in bearings and external bearings. In the structural version of the built-in bearing, the bearing is lubricated by the conveyed material. The twin-screw pump working chamber of the external bearing structure is separate from the bearing. Due to the structure of the pump and the side gaps between the screws, it can transport non-lubricating media. In addition, adjusting the synchronizing gear causes the screw to not contact and transmits half of the output torque to the driven screw. Like all screw pumps, the externally mounted twin-screw pump also has self-priming capability, and most of the pump delivery elements are themselves in a double-suction symmetrical arrangement that eliminates axial forces and also has a large suction height.

The twin-screw pump series is divided into two categories: single-suction twin-screw pump and double-suction twin-screw pump. This series of products has special screw type lines and special structures matched with them. It is widely used in various industries such as petroleum, chemical, metallurgy, steel, electric power, shipbuilding, pharmaceutical, food, building materials, etc. The wide range and complexity of application conditions are unmatched by other pump products. These characteristics also make this series of pumps have potential development prospects.

main feature:

The pump adopts a double suction structure, and both ends of the screw are in the same pressure chamber, and the axial force can be balanced by itself. The bearings at both ends are externally mounted and lubricated with lubricating oil (fat) alone, so they are not affected by the conveying medium. The two screws are driven by a pair of synchronous gears, and the tooth faces of the screw are not in contact with each other, leaving a slight gap. The impurities in the medium cannot directly wear the tooth surface of the screw (except for flushing). Except for some small displacement pumps (below 2W.W4.0), there are generally internal flow safety valves on the pump body. When the discharge pressure exceeds the rated value, it has a certain protective effect. There are two kinds of inlet and outlet directions on the pump body, one is horizontal and horizontal, and the other is horizontal and vertical. The user can choose according to his own needs.
