Stainless steel screw pump

Product Overview <br /> Single-screw pumps have been widely used in developed countries. Most foreign countries call single-screw pumps "Mono pumps" "MONOPUMPS", and Germany calls "eccentric rotor pumps." Due to its excellent performance, the scope of domestic application has also expanded rapidly in recent years. Its biggest features are strong adaptability to the medium, stable flow, low pressure pulsation, and self-priming energy, which cannot be replaced by any other pump type. At present, our unit's products have been self-contained and the pressure is 0.4∽1.2MPa, which can meet the different needs of customers for single screw pumps.

Features
Single screw pump is a new type of pump that works according to the principle of reciprocating meshing volumetric type. The transmission can be directly driven by a coupling, or it can be transmitted by a low-speed motor V-belt, transmission, stepless transmission and other devices. The flow rate is 0.8-150m3 / h, and the pressure is 0.4-1.2MPa.

Product use <br /> Environmental protection 'Industrial sewage, domestic sewage, sludge turbid water containing solid particles and short fibers, especially used in oil-water separator plate and frame filter press equipment.
Shipbuilding industry: wheel bottom cleaning, oil and water, oil residue, oil sewage and other ring transportation.
Petroleum industry: transporting crude oil, mixtures of crude oil and water, coalfield gas and water, pouring polymers into the formation, etc.
Medicine, daily chemical: all kinds of viscous pulp, emulsion, various ointment cosmetics, food canning industry: all kinds of viscous starch, strong distiller's grains, grain residues, all kinds of sauces, pulps, solids, slurry construction industry: Cement mortar, lime slurry, coatings, paste spraying mining industry: solid particles in the mine, groundwater, sludge hydrochemical industry: various suspensions, greases, various colloidal pulps, various adhesive printing, papermaking : High-viscosity inks, PVC polymer plastic pastes for wallpaper and pulps of various concentrations, short-fiber pulp industrial boilers, power plants: Performance parameters when coal water slurry is transported at a fixed speed

Explanation:
1. The above performance parameters are the test data during the normal temperature water test;
2. For different media and different speeds, the performance parameters will change. The flow value is inversely proportional to the concentration and viscosity, and is proportional to the speed.
3. The user must choose the type of pump according to the use requirements, the condition of the conveying medium, and the selection principle, or negotiate with the company's technical department to determine the type of pump.
4. For the coal-water slurry pump's transmission mode is gear speed matching electromagnetic speed regulating motor or mechanical stepless variable speed motor, the flow rate is steplessly adjustable as the speed changes.
