GW model is the latest developed a new screw, relative to the other series, the whole body made of stainless steel die-casting, a higher degree of hygiene, easy cleaning without dead ends, and more energy-saving and environmental protection, was adopted b
GW-type screw pump
A, GW series single screw pump Product Overview:
GW-type screw pump rotary displacement pump is engaging an internal main part is to work with the eccentric screw (rotor) and fixed bushing (the stator), due to the special geometry of the stator and rotor respectively formed several separate sealed container chamber, the operation of the rotor, the respective seal cavity a uniform continuous medium from the suction side to the delivery end of the extrusion, the internal flow rate is low, the volume remains the same, pressure stability, and thus does not produce vortex agitation. It can be used to transport neutral or corrosive liquids, clean or abrasive liquids, gases, or easy to produce a liquid containing bubble liquid, high or low viscosity, including liquids containing fibrous and solid matter. Long-term continuous work to maintain steady flow, with good self-absorption capacity.
 
Two, GW-type single screw pump features:
1, variable delivery; displacement proportional to the speed, or the speed motor via transmission means to achieve displacement control.
2, self-absorption ability, not water, check valves, etc., directly pumped liquid.
3, can deliver a high concentration, high viscosity and water content of solid particles in a liquid, the weight ratio of the highest concentrations of up to 40%.
4, low-flow but also to maintain a high discharge pressure, discharge pressure has nothing to do with speed.
5, transmission fluid stability, no over-current, pulsating and stirring phenomenon no anti-coagulant structure of liquid. Transport stable non-foaming, especially for shear sensitive media.
6, the pump can be reversed; the liquid flow by the pump to change the direction of rotation for the pipeline need backwashing occasions.
7, mixed with air suction side does not affect the pumping for gas liquid.
8, simple structure, easy disassembly and maintenance.
 
Three, GW-type single screw pump is widely used:
1, the food industry: transport meat, potato salad, miso paste type body, concentrated fruit juice, jam, vegetable products.
2, the brewing industry: transport all kinds of residues lees, yeast, fermented and cast ingredients.
3, the sugar industry: syrup, saturated slag, waste residue concentrated, crystallized sugar paste; milk, cheese.
4, the textile industry: transportation synthetic fluid, viscose liquid, dyes, inks, nylon powder-liquid.
5, the paper industry: pulp slurry transportation, talc slurry, polishing resin paste.
6, the oil industry: transport a variety of oil, oil products, refinery sludge, industrial waste water.
7, the chemical industry: all kinds of latex, suspensions, ointments, shampoos, paints, pigments.
8, construction: conveying mortar, plaster, asphalt, tar, sand slurry, paint.
9, the mining industry: transportation oxide and wastewater, mine drainage, liquid, scum.
10, a special form of a single-screw pump: forced feeding screw with rectangular hopper with an auger on the link for gravity but can not contain a liquid medium, similar to when transporting liquid slag, can also be installed stirring rods to prevent precipitation. When high concentrations of slag liquid, add crushed can squeeze big funnel, to prevent clogging. The pump can be equipped with various types of drives, with the most suitable for three-phase gear motor.
 
Four, GW-type single screw drives available in the form of:
1, the motor directly connected: Common motor directly connected to the pump through a coupling
2, stepless Manual: Manually stepless speed motor, connected via a pump coupling
3, gear type: motor + gear reducer, the pump is connected through a coupling
4, inverter motor: ordinary frequency motor or inverter motor + gear reducer, the pump is connected through a coupling

         2, if necessary, optional manual speed motors or gear motors.
         3, the table is based on the parameters of the medium water 20 ℃, the viscosity is measured 1mm2 / time.
         4, when the transmission of high viscosity materials or abrasive material particles, suggested the use of gear motors at low speed.
         5, before starting the pump body into the amount of detergent or soap and other lubricating fluid, and then move the tube clamp plate after a few turns before starting, non-air operation.
