    摘要： At least one of the scroll members is composed of a metallic insert having substantial the same configuration of the scroll member, i.e. an end plate and spiral wraps fixed to and extended from the end plate. The metallic insert has anchor holes and connecting holes for bonding the plastic coating layer on to the metallic insert. The anchor holes also serve as gas escaping passages during injection molding process. The mold has multiple poring gates to minimize the pressure gradients across the spiral wraps during the injection molding process. The metallic insert has also tubers sticking out from the tip of its spiral wraps. The tubers are firmly held by the mold in the injection molding process to prevent movement of the spiral wraps under the pressure from the injected plastic flow. The metallic inserts can be fully or partially coated by the plastic compound such that there is no metallic to metallic contact between the scroll members during operations.

    摘要翻译： 涡旋构件中的至少一个由具有与涡旋构件具有相同构造的金属插入件构成，即端板和固定到端板并从端板延伸的螺旋形涡卷。 金属插件具有用于将塑料涂层粘合到金属插入件上的锚定孔和连接孔。 在注射成型过程中，锚孔也用作气体逸出通道。 该模具具有多个穿孔门，以在注射成型过程中最大程度地减小跨越螺旋卷的压力梯度。 金属插入物还具有从其螺旋形包装的尖端伸出的块茎。 块茎在注射成型过程中被模具牢固地固定，以防止螺旋缠绕物在压力下从注入的塑性流动中移动。 金属插入物可以被塑料化合物完全或部分地涂覆，使得在操作期间在涡旋构件之间没有金属与金属的接触。

    摘要： The invention relates to a pump housing (2) comprising a dual-wall casing (3) which enables a first fluid (4) to flow at least partially around a compression chamber (5) for compressing a second fluid (6), said compression being performed with at least two elongated rotors (7, 8). The dual-wall casing (3) comprises: (i) a first wall (10) which defines the volume of the compression chamber (5), and (ii) a second wall (11) which extends around the first wall (10) at a distance (12) from same such as to enable the first fluid (4) to flow therethrough. The pump housing (2) consists of two subassemblies (13, 14), namely a first subassembly (13) and a second subassembly (14), which are assembled along a sealing surface (15) that is essentially orthogonal to the longitudinal axes (70, 80) of the rotors (7, 8). Both the first subassembly (13) and the second subassembly (14) are characterised in that they consist of a rigid element (16) which is moulded from a first thermally-conductive material and which comprise two opposing faces, namely a first face (18) and a second face (19). According to the invention, the above-mentioned first wall (10), which is moulded with the rigid element (16), is disposed beyond the first face (18) such as to extend essentially orthogonally thereto, while the second wall (11) is also disposed beyond the first face (18) such as to extend essentially orthogonally thereto, but in parallel to a fourth face (21) of the first wall (10) without being joined to same. In addition, cut-outs (23) are recessed into the first face (18) such that each cut-out forms at least one housing for a first member (9) that is used to guide the rotation of one of the opposing ends (71, 72, 81, 82) of one of the rotors (7, 8).

    摘要： Disclosed is a liquid ring pump with one or several stages, each of which comprises a working chamber, an impeller that is eccentrically mounted therein, flat control disks that axially delimit the working chamber on both sides, and ducts or chambers that are located adjacent to the control disks and deliver and discharge the transport gas to and from the working chamber. The inventive liquid ring pump is characterized in that the control disks are embodied in the same manner with identical suction ports and pressure ports while ports that are not needed are covered on the side facing away from the impeller.
