Installation Instructions

 Installation and conditions of use: The unit generally used horizontal installation. Transport medium is -10 ~ 85 ℃, maximum viscosity of 20000mm2 / s, the solid particle content (mass ratio) of up to 40%.
Hao Star GS-type single screw Caution:
1.GS type single screw pump must first be determined before starting the running direction shall not be reversed.
2.GS type single screw pump medium is strictly prohibited in the case of non-air operation, to avoid damage to the stator.
3 a few days after a new installation or downtime G-type single screw pump can not start immediately, should first G-type single screw pump body into the amount of oil, and then pipe clamp plates move a few turns before they start.
4.Conveyor high viscosity or containing particles and corrosive media, the application of water or solvent to wash, to prevent obstruction, so the next start-up difficulties.
5 Winter effusion should be queued to prevent cracking.
6.GS type screw pump during use should be regularly lubricating bearings inside and found that there is seepage shaft, to the timely processing or replace seals.
7 In the event of abnormal operation should immediately stop checking reasons for troubleshooting.

Pump selection

     Hao Star GS-type single screw pump design speed of conveying water or water of similar non-corrosive liquids permitted maximum speed, in practical use due to the nature of the media and life requirements are different, and selection should generally be lower than the design speed of the high viscosity and particle-containing medium, the general design 1/2-1/3 or lower speed, low-speed on pump wear favorable, but the wear after use because the stator flux decline, then may be appropriate to increase the speed, to compensate for the drop in traffic but also for regular policy. Transmission medium temperature should be -10 ℃ ~ 80 ℃ special cases up to 120 ℃.
     Hao Star GS-type single screw pump for each level (the stator of a lead) normal pressure is 0.3 ~ 0.6Mpa, a short time (less than 30 minutes) allowed up to 0.6Mpa, when worn at the same volumetric efficiency when the output pressure to gradually decline.
     Hao Star GS-type single screw pump to send water when maximum suction lift of 3 meters, the actual use is not recommended over 2.5 meters, when pumping high viscosity media should be based on positive pressure inhalation.
