Abstract

The invention discloses a flow controllable two-screw pump which comprises a pump body, wherein the pump body comprises an overflowing chamber, a gear transmission chamber and a gear reduction chamber, wherein the overflowing chamber is arranged at the left side of the gear transmission chamber; the gear reduction chamber is arranged at the right side of the gear transmission chamber, and is connected with a driving device; the pump body is internally provided with a transmission screw; the transmission screw comprises a driving transmission screw part and a driven transmission screw part; a liquid inlet and a liquid outlet are formed in the overflowing chamber; the liquid inlet is positioned at the lower end of the overflowing chamber, and is connected with a liquid inlet cavity; the liquid outlet is positioned at the upper end of the overflowing chamber, and is connected with a liquid outlet cavity; and the liquid outlet cavity is internally provided with a flow control device. The flow controllable two-screw pump is simple in structure, novel in design, high in pertinency, high in automation degree, low in noise, high in adjustability and precise in flow control, and is scientific and convenient, and the fluid transportation problem of a pipeline is solved well. The flow controllable two-screw pump can transport most liquid such as water and oil, and is wide in application range, high in control precision, and high in adjustability.

Description

technical field [0001] The invention relates to a twin-screw pump with controllable flow. Background technique [0002] Progressive cavity pumps are so-called positive displacement pumps in which the rotating extruder has a shape similar to the spindle thread. Progressive cavity pumps consist of two or more opposing rotors and a casing that surrounds the rotors. These rotors are provided with a regular, thread-like texture and engage in a gear-like interlaced manner. These rotors are also referred to as spindles and have at least one first shaft section and a textured section with a threaded helical texture. The hollow space formed by the three structural elements (pump housing, first spindle and second spindle) forms the delivery chamber for the delivery medium. When the spindle rotates, the conveying chamber moves out in the machine direction and conveys the medium from the suction side to the pressure side within the pump housing. This type of pumping is especially su...
