G-type single screw pump

The G-type single screw pump belongs to the rotor type positive displacement pump, which relies on the meshing of the screw and the liner to produce volume changes in the suction and discharge chambers to transport liquids. It is a closed screw pump with internal meshing, mainly composed of a liner (stator) with a double head spiral cavity and a single head spiral screw (rotor) that meshes with it in the stator cavity

The G-type single screw pump belongs to the rotor type positive displacement pump, which relies on the meshing of the screw and the liner to produce volume changes in the suction and discharge chambers to transport liquids. It is a closed screw pump with internal meshing, mainly composed of a liner (stator) with a double head spiral cavity and a single head spiral screw (rotor) that meshes with it in the stator cavity. When the input shaft drives the rotor to rotate around the center of the stator through a universal joint, the stator rotor pair continuously meshes to form a sealing chamber. These sealing chambers move uniformly in axial direction without changing their volume, transporting the conveying medium from the suction end through the stator rotor pair to the press out end. The medium sucked into the sealing chamber flows through the stator without being stirred or damagedThe inner surface of the liner has double threads, with any cross-section being a long circle. The two ends are semicircles with a radius of R (equal to the screw cross-section radius), and the middle is a straight segment with a length of 4e. Any cross-section of the liner is the same elongated circle, but staggered at an angle from each otherAfter the screw is inserted into the liner, closed chambers are formed between the surface of the screw and the inner thread surface of the liner, and any cross-section is also divided into two crescent shaped chambers, upper and lower. When the screw rotates, the volume of a good selling studio near the suction chamber gradually increases, forming a negative pressure, and the liquid is sucked into the studio under the action of the pressure difference. As the screw continues to rotate, the working chamber volume continues to increase, and this chamber is closed, pushing the liquid axially towards the pressure chamber. At the same time, the upper and lower studios alternately cycle in and out of the liquid, so the liquid is continuously pushed axially from the suction chamber towards the pressure chamber

Product features of G-type single screw pump:

Due to its structure and working characteristics, G-type single screw pump has many advantages compared to piston pump, centrifugal pump, blade pump, and gear pump:

1. It can transport media with high solid content;

2. The flow rate is uniform and the pressure is stable, which is more noticeable at low speeds3. The flow rate is directly proportional to the pump speed, thus having good variable adjustability4. One pump is versatile and can transport media with different viscosities5. The installation position of the pump can be tilted arbitrarily6. Suitable for transporting sensitive items and items that are easily damaged by centrifugal force7. Small size, light weight, low noise, simple structure, and convenient maintenance
