An Overview
The series of submersible three-screw pumps is a lubricating oil delivery product with small size, low noise, low efficiency, high life and long life specially developed for lubrication equipment according to market demand. It is produced according to B/ design. It consists of a driving screw and two driven screws that are meshed with each other and fixed in a bushing. The screw profile is composed of a double-headed cycloid and arc tooth shape. The screw pair and bushing are installed in the pump body. When the driving screw rotates under the driving of the prime mover, the main and driven screws form a sealed cavity under a certain meshing spiral surface length. The driven screw is pushed by the conveyed liquid medium to rotate due to the pressure difference on both sides of the spiral surface. At this time, the conveyed liquid enters the pump. The suction port enters the sealing chamber evenly and continuously along the axial direction, and smoothly and without agitation reaches the discharge chamber from the pump suction chamber, thereby achieving the function of transporting liquid media.
2. Structural Features
It has strong self-priming ability and can transport liquid media that is lubricating and does not contain solid particles.
Compact structure and high mechanical efficiency.
Low noise, low vibration, stable performance, easy use and maintenance, and long life.
Designed with a special oil storage device, it can avoid the trouble of refueling during the second startup.
It has a variety of connection structure forms to facilitate design and selection.
For pump outlet diameters (inclusive) and below, the inlet and outlet connections adopt cylindrical pipe threads, and above, flange connections are used.

Pump set materials and materials usage description:
According to the physics of the transmission medium Depending on the chemical properties, pump materials have different material combinations. The following parts and materials list is for reference:
List of three-screw pump application industries
In heating equipment, fuel system, burner system, boiler heating system, thermal power generation The factory is used for fuel injection, diesel, fuel supply and transfer pumps, loading pumps, unloading pumps, and backfill pumps.
In the metallurgical and steel plant industry, it is used as a lubrication pump in the lubrication system, as an oil supply pump in the hydraulic system, as a combustion pump in the combustion system, and as a transport backflow pump in the oil depot.
In mechanical machine lubrication, gear transmission lubrication, large oil film bearing oil supply circulation cooling system, we make liquid supply pumps, oil supply pumps, booster oil pumps, circulation pumps, lubricating oil pumps and remote control motor pumps, and three-screw oil pump devices.
It is used as a hydraulic pump in the hydraulic transmission device in the hydraulic elevator industry, and as a delivery pump for resin, pigment, latex, ink, paint, glycerin and paraffin in the chemical industry.
In the petroleum refinery refining industry, it is used to transport crude oil, heavy oil residue, asphalt tar emulsion, and is used in the refining process of high-temperature viscous products, such as asphalt vacuum tower bottom oil and residual fuel loading, transportation and liquid supply pumps.
In the engine room of oil tankers, cargo ships, merchant ships and many combat ships, in crude oil pipeline services at ports and terminals, and in the collection, pressurization and loading of barges and ships, it is used to deliver pressurized fuel injection and main engine lubrication pumps and main engine lubrication oil pumps. Three-screw pumps are also widely used in lubricating oil pumps and marine hydraulic device pumps, marine hydraulic pumps, anchor machines, hydraulic winch drive pumps, etc.
In shipyards/machine building plants, such as separators, superchargers, engines, etc., oil delivery systems, fuel treatment systems, etc. Lubrication Oil systems are also widely used in lubrication and hydraulic systems in propulsion systems.

It is also widely used in industrial fields such as oil fields and offshore platforms to transport crude oil, latex, etc.
In the food industry, it is used in oil factories, wineries and food factories to transport edible oil and animal oil. , vegetable oil, alcohol, honey, sugar juice, toothpaste, milk, cream, chocolate
In the building materials industry, it is used as ignition oil pump and heavy oil fuel pump in the kiln of the glass factory, ceramic factory, refractory material factory, cement factory
Four performance characteristics
