Motor can be equipped with: ordinary motor, frequency conversion motor, explosion-proof motor, gear reducer motor, electromagnetic speed control motor, stepless speed control motor

Product principle:
Single screw is a new type of pump that works according to the principle of revolving meshing volumetric type. The main working parts are eccentric screw (rotor) and fixed bushing (stator). Due to the special geometric shapes of the two parts, separate sealed chambers are formed respectively. The medium flows uniformly in the axial direction, the internal flow rate is low, the volume remains unchanged, and the pressure is stable, so turbulence and agitation are not generated. The output pressure of each stage pump is 0.6MPa, the head is 60m (clear water), and the self-priming height is generally 6m. It is suitable for conveying medium temperature below 80°C (up to 150°C for special requirements). Because the stator is made of a variety of elastic materials, this pump has the characteristics of conveying high-viscosity fluids and conveying media containing hard suspended particles or media containing fibers, which are incapable of general pumps, and its flow rate is proportional to the speed. .
The transmission can be directly driven by a coupling, or variable speed by means of a speed-adjusting motor, V-belt, gearbox and other devices.
This kind of pump has few parts, compact structure, small volume, simple maintenance, rotor and stator are the vulnerable parts of the pump, simple structure, easy to assemble and disassemble.

Rotor:
The rotor has high-quality surface characteristics. In order to ensure the quality of the rotor and the corresponding surface quality, production, grinding and coating processes are used. Through the use of various grinding and polishing processes, the surface roughness will be greatly reduced, thus improving the fatigue resistance and corrosion resistance of the rotor, as well as the wear resistance and hardness characteristics of the rotor.

Benefits of surface optimization:
Reduced starting torque and operating torque, improved hydraulic capacity measurement efficiency, smooth operating characteristics, and increased service life

stator:
Only the full cooperation between the rotor and the starter can maintain the working efficiency at a higher level and make the transmission power lower. For this reason, a stable geometry between the two transmission elements is essential. The calibrated magnetic core can avoid the obvious thinning of the starter end.
This will ensure smooth operation throughout the length of the starter.
Generally, Fuquan manufactures stators specifically for each size and pressure level. It is this method of producing stators according to specifications, so that stators with sealing flanges at both ends of the pipeline can be manufactured.

Sealing form:
The safety seal of the rotating shaft is a special challenge. The shaft seal is selected according to the operating conditions and the characteristics of the transmission medium. Customers can choose a suitable shaft seal according to the needs of specific working conditions.
It can be equipped with a continuously variable transmission according to the customer's different media requirements, and the motor speed and output flow can be manually adjusted.


Application areas:

Hygienic single screw is mainly dedicated to conveying viscosity and poor fluidity media, such as: food industry: tomato sauce, mashed potatoes, peanut butter, yogurt, fresh cream, ice cream, cheese block, whey, beer, wort, yeast, juice Drinks, vegetable paste, jam, jelly, etc. Pharmaceutical industry: various types of pill paste, extract, emulsifier, cough syrup, biological products, cod liver oil, royal jelly, etc. Daily chemical industry: shampoo, hand sanitizer, toothpaste, cosmetics, soap, etc.
