Product Description
IntroductionG Single Screw Pump
GERNERAL
The series G of Single Screw Pump is a rotating mesh and positive displacement pump. The main working parts are the Eccentric Screw ( Rotor ) and the Bush fixed ( Stator ).
With the special geometry of these two parts, dividing the cavity into two independent sealed chambers. Fluids flow to the direction of axis with low flowrate, and the volume and pressure remain stability, so it will not have swirl and stir inside.
OUTPUT PRESSURE 1.2MPa for each class of pump
HEAD 120M for water
SUCTION PRESSURE 120Bar
TEMPERATURE MAX . 80ºC, It can reach to 150ºC for special request.
FLUIDS For transporting high viscosity, hard suspended partilcles and fiber with its varity of flexible materials.And the flowrate is proportional to the speed.
ELECTRIC MOTOR COUPLING It's direct and you can use motor speed, wedge shaped belt and transmission case etc. to shift gear.
FEATURE Fewer accessories, compact structure and facilitate maintenance. The rotor and stator are easily damaged parts. But don't worry, it's easy disassembly for its simple structure.
Application
Single Screw Pump of series G is a kind of Gerneral Pump. Its speed can be switched freely and its output rated pressure can be increased by its level. The pumps can be widely used in many different areas.
Especially to be emphasised in the application in plant s of:
Environmental protection:
oil-water separator,plate and frame filter press for conveying industrial sewage, domestic sewage and sludge and filth which contain solide particles and short fibers
The shipping industry:
the bottom of ship cleaning, plants for conveying oil-water, oil-residue and oily sewage.
The petroleum industry:
oil delivery
In recent yeas, it pumped mixture of oil and water, coal field gas and water from the kilometres' deep undergroud successfully so that greatly reduced the cost. Then you can use the screw pump to pour polymer into layer to increase the efficiency of the exploitation of oil fields by the late time.
The medical and daily health product industry:
plants for conveying dope, oil water emulsion and salve cosmetics.
The canned food industry:
plants for conveying viscous starch, edible oil, honey, syrup, fruit puree, cream, minced fillet and minced meat and their residues.
Brewing industry:
plants for conveying viscous liquid fermentation, thick lees, residue of food product, all kinds of syrup and paste and mucus which contain blocky solid matter.
The construction industry:
plants for conveying cement mortar, lime mortar, coating material and other pasty material.
The mining industry:
plants for discharging groundwater and sewage which contain solid particle to the surface.
The chemical industry:
transport all kinds of suspension, grease, colloid and adhesive
The printing & paper industry:
plants for conveying high viscosity painting ink, PVC high molecular plastic paste of wall paper, paper pulp and short fiber stuff.
NOTES
- Make sure the running direction before starting the press. Do not operate it without any fluid in sake of protecting the stator. Do not start the pump immediately when it just installed or stop it for several days. Please pour some engine oil into the casing first and use pipe wrench to running some laps before you start the press. Please wash the pump by water or solvent after conveying fluids with high viscosity , solid particles and corrosive. Please clean out liquid loading in winter in order to avoid frost cracking. Please add lubricating oil regularly into the bearing house during the operation. If you find some leakage at the shaft end, please deal with it in time and change the oil seal. Please stop the pump immediately if you find something unusual happened during the operation, check it up to trouble shooting.
Common faults and trouble shooting
| Common faults | Causes | Trouble shooting |
| Can not start-up | - new pump and stators are over tight low pressure and electric current over high viscosity of fluid
| - use specific tools to start-up by manual check it up and adjust dilute the fluid
|
| Fluid can not be out of the pump | - wrong running direction something wrong in suction pipe over high viscosity of fluid something wrong with the stator, rotor or driving parts blocking inside the pump
| - adjust the running direction leak check and open the import and export of the valve dilute the fluid check and replacement clean out and replacement
|
| Low flowrate | - leak pipeline
B valves are not all opened or partial blockage
C low speed
D rotor or stator abrasion | A check and repair the pipeline
B open all the valves and unclog
C adjust the speed
D replace the abrasion parts |
| Low pressure | A rotor or stator abrasion | A replace the rotor or the stator |
| Motor overheated | A fault of motor device
B over-high out pressure, motor device overloaded
C the stator burnout or paste to the rotor | A check the motor device, pressure, electric current and storage battery
B check the head of delivery, open the exit valve and unclog
C replace the abrasion parts |
| A sharp decline of flowrate and pressure | A sudden blockage and leekage at pipeline
B stator abrasion badly
C sudden change of the viscosity of fluid
D sudden decline of pressure | Refer to the trouble shooting upon |
| A large number of leak at the shaft seal | A wadding abrasion
B mechanical seal mutilation | A compress or replace the wadding
B restoration or replacement |
