Install and use conditions: Units generally horizontal installation. Transmission medium is -10 ~ 85 ℃, the highest viscosity 20000mm2 / s, solid particle content (mass ratio) of up to 40%.

Hao Stars GS-type single-screw pump to use Considerations:
1.GS single-screw pump running pre-boot we must first determine the direction, shall not be reversed.
2.GS-type single-screw pump is strictly prohibited in the absence of media cases, empty running, so as to avoid damage to the stator.
3. The new installation or down a few days later G-type single-screw pump, can not immediately start, should first G-type single-screw pump body into the amount of oil, and then pipe clamp plate start moving only after a few trips.
4. Transport of high viscosity or containing particles and corrosive media, the application of water or solvent to wash, to prevent the obstruction, so as to avoid difficulties in the next start.
5. In winter should be fluid line to prevent the Frost Crack.
6.GS the process of using bearing-type screw pump should be regularly lubricating the box and found that when the shaft there is seepage, a timely processing or exchange seals.
7. In the event of abnormal operation should immediately stop checking reasons, troubleshooting.

Pump Selection
Hao Stars GS-type single-screw pump design speed for the delivery of water or water similar to the non-corrosive liquids when the maximum speed allowed in the actual use of media property and life due to different requirements for use in general should be lower than when the design speed, right high viscosity and containing granular media in general a design speed of 1/2-1/3 more or less, low-speed on pump wear and tear of a favorable, but after use due to wear and tear of the stator flows have declined, this time may be appropriate to improve the speed to compensate for the drop in traffic for regular policy. Transmission medium temperature should be at -10 ℃ ~ 80 ℃ special cases up to 120 ℃.
Hao Stars GS-type single-screw pump for each level (the stator of a lead) and normal pressure 0.3 ~ 0.6Mpa, short (not more than 30 minutes) to allow up to 0.6Mpa, when worn in the same volumetric efficiency of the output pressure should gradually decline.
Hao Stars GS-type single-screw pump to send the maximum absorption of water when the process is 3 meters, the actual use of the proposed no more than 2.5 m when pumping high viscosity media, should be based on positive pressure inhalation.
