LG vertical screw

A, LG vertical screw pump Product Overview: LG vertical screw pump, also known as concentrated belong rotor displacement pump, LG vertical screw for the vertical screw, mainly to solve the medium conveying high viscosity base performance specially adapted High viscosity media. LG vertical screw can be required to design and manufacture in line with user needs was the length of the user. LG vertical screw is to rely on the screw and meshing with each other to produce the volume change of the bush in the suction chamber and the discharge chamber to deliver liquid. It is a closed internal meshing single screw, the main working parts made with a double spiral cavity liner (stator) and the single-head auger screw cavity meshing with the stator (rotor) component. When the input shaft universal joint drive by the rotor rotating around the center of the stator for the planet, the stator - rotor deputy to form a sealed chamber continuously engage these sealed chamber volume unchanged for uniform axial movement of the transport medium from the suction side through the stator - delivered to the rotor deputy press out the end, the suction chamber sealed medium flows through the stator without being agitated and destruction. Double threaded bushing having an inner surface, the arbitrary cross section of a long circle, ends with a radius R (equal screw section radius) of the semicircle, the middle is the length of the straight section 4e. Bush arbitrary cross section are the same length round, but at an angle to each other staggered. After loading the screw bush is formed between the inner surface of the liner of the screw threaded surface of one enclosed chamber, but also arbitrary cross section is divided into upper and lower two crescent-shaped studio. When the screw is rotated, the first volume of a studio near the suction chamber increases, a negative pressure, under the action of the pressure of the liquid is sucked into the studio. With continued rotation of the screw, the working chamber volume continues to increase to the maximum after the studio closed, and the liquid in the axial direction toward the pressure out of room. At the same time two studios alternately up and down cyclically suction and discharge liquid, so that the liquid is continuously axially from the suction chamber to the pressure of the chamber. Two, LG vertical screw pump characteristics: LG vertical screw special working shaped cavity can transport medium, hard, soft solid particles and long fiber containing suspension (or solids are polygonal sharp, high wear particles) and The filament or entrained gas medium (liquid, solid, and Gas). 1, the solid particle size models pump "rotor" eccentricity (e) related. 2, the concentration by volume solids concentration, up to 40% (e.g. up to 70% powdered particles). 3, fiber length and pump models "rotor" lead-related, allowing the longest fiber media with a viscosity of up to 1,000,000 mpa.s (cp) material can be effectively conveyed. The vertical pump thick with self-attracting features: a liquid medium can attract up through the pipe from a height of up to 6-8.5 meters. Pump speed and flow rate is linear relationship between the pump speed can be set depending on traffic. Vertical screw can also be variable speed or variable speed to meet user requirements for various properties, flow accuracy (± 1%), can be used as a metering pump for laboratory, pharmaceutical, and other ingredients. Pressure (head) generate and "Stator" screw lead (T) related to a lead (T) output pressure of 0.6 Mpa (6 0 米 head) pressure level, two and a lead of two pump pressure 1.2Mpa a (1 2 0 m lift). LG vertical screw pump according to any one of the conditions necessary models can be manufactured, vertical, oblique-mounted, removable small vehicle type and other types of screw. Another member of the screw less, the structure is not complicated, demolition, easy maintenance, even first time users can easily grasp short periods. The single screw due to "certain child" is an elastic body and "rotor" is made of metal, so the pump can not be a state in the absence of medium dry running and pump damage hydraulic components. Three, LG vertical screw pump performance parameters: diameter range: 25-150mm flow range: 0-55m3 / h Head range: 0-120m
