Pumps pump thick mud pump G-type single screw pump paste pump

Product Name: stainless steel screw a screw pump Overview screw is the use of screw rotation to suction fluid. Screw screw in the middle for the initiative, motivated by the original rotation, both sides of the screw is driven screw with the active screw for reverse rotation. Lord, driven screw thread are double thread. Due to the close intermeshing with each screw and screw and liner tube wall, between the suction port and the discharge outlet of the pump, it will be divided into one or more of the sealed space. With the rotation and intermeshing screws, which are sealed space in the suction side of the pump evolving, the suction chamber in which liquid is sealed, and from the suction chamber along the screw axis continuously push to move the discharge end, it will be closed in the space continuous discharge of liquid, like the case of a nut rotation in the thread that is constantly moving forward, which is the basic principle of the screw pump. As can be seen from the above works, screw pump has the following advantages: 1, a wide range of pressure and flow. A pressure of about 3.4-340 kgf / cm 2, the flow rate of up to 18600cm3 / min; 2, liquid transport type and a wide viscosity range; 3, because of the lower inertia force rotating member within the pump, it is possible to use a high speed ; 4, inhalation good performance, with self-absorption capacity; 5, a uniform continuous flow, vibration, low noise; 6, compared with other rotary pumps, gas and dirt to enter the less sensitive; 7, solid structure, installation maintenance easy. Screw disadvantage is that the higher the screw machining and assembly requirements; pump performance liquid viscosity sensitive. Second, the working principle of the screw pump screw pump belongs to push displacement pump, the main components of the rotor and the stator, the rotor is within a large lead large teeth and a smaller spiral through high screw (rotor) is mated to the stator headed screw line and collar, so that between the rotor and the stator to form a space to store media, when the rotor is operating within the stator, the media in the axial direction from the suction side to the discharge motion. Third, the characteristics of a screw pump, the stator and rotor of the contact wire spiral seal chamber and the discharge chamber income completely separate the pump having a barrier effect of the valve; 2, enabling liquid, gas, multiphase solid; 3, When the volume of fluid flow within the pump does not change, and no Swiss pulsating flow agitation; 4, the volume of the cavity formed by the stator elasticity can effectively reduce abrasion when conveying a medium containing solid particles; 5, referred to the input 50000Mpa · s having a viscosity of up to solid content up to 50%; 6, flow and speed is proportional to, the amount can be achieved by means of the governor automatically adjust the pump can reverse transport. Screw has the following advantages: 1, compared to screw and centrifugal flow without having to install valves are stable linear flow; 2, and piston compared to screw self-priming ability, strong suction height; 3, and diaphragm Compared to screw pump can transport a variety of mixed gas containing impurities and solid particles or fibers of the media, but also transport a variety of corrosive substances; 4, and a gear compared to screw pumps can transport high-viscosity material; 5 column piston pumps, diaphragm pumps and gear pump is different, screw can be used for pharmaceutical filling and measurement.
