3GR three screw

Three screw including 3G Universal , 3gr three screw , 36X6A-W21, 3GC marine -type and special -type , three screw pump is a positive displacement pump rotor , as driven screw on the active engagement of the screw and spiral grooves and their mutual and bushes with three- hole surface to form between the inlet of the pump seal chamber several class action , these dynamic seal chamber will keep the liquid from the pump inlet to pump outlet axial movement , and to progressively boost the body fluids , thereby forming a continuous, smooth , axial movement of the pressure of the liquid .
The infusion of three screw body for a variety of solid particles, non-corrosive oil and oil-like liquid lubrication , 3gr three screw , 36X6A-W21 viscosity of the fluid is 1.2-100E (3.0-760cst), high can also be transported through the viscosity of the liquid viscosity after heating .
Flow range 0.2-590m / h, maximum working pressure of 100bar, the maximum temperature of 150 ℃
A structure is simple : with a variety of structural forms , generally low flow 0.2-6.5m / h, three screw pump 3gr , 36X6A-W21 's pump and bushings into one ( collectively pump ) to the end face seal mechanical seal.
Moderate traffic over a separate pump liner is secured to the pump body parts , high flow pump more than double suction structure made of horizontal installation , seal sealing two mechanical seals and packing , depending on the transmission medium .
Marine pumps are installed in the form of both horizontal and vertical , the original motivation for the AC and DC marine motors.
2 . Long life: three screw initiative screw driven by a motor , Lord, from no mechanical contact between the rods , and the output from the pressure of the liquid driven around the axis of rotation from the fierce , Lord, from between the rods , screws and bushings are Individually layer of protection between the film and thus minimal mechanical friction pump life called semi-permanent .
3 . The fluid in the pump body axially uniform linear motion , so the pressure pulsation , flow stability , low noise, small part due to the rotation inertia , the starting torque and low vibration .
4 . With high suction capacity .
5. To ensure the pump , 3gr three screw , secure, medium flow over Lo defended 36X6A-W21 motor pump and piping system are with safety valve when the pressure exceeds the set pressure of the safety valve . High pressure oil will flow back to the pump inlet .
