The scope of application
WRJ Outer Lubrication Gear Pump is suitable for conveying non-lubricated, corrosive, hygienic and hygienic fluids that do not require high solids or do not contain the usual viscosity and high viscosities of solid particles, fibers, etc. Medium temperature 160 ℃, viscosity 5-1500cst.
Structural features
The main structural feature of WRJ external lubrication gear pump is that the working wheel and the power transmission wheel of the transmission medium are separated. The working wheel of the transmission medium does not carry the transmission power, and the power transmission gear does not come into contact with the medium to be conveyed. The parts in contact with the medium are all wear-resistant alloy steel. Anti-benzene mechanical seal, no leakage.

Seamless carbon steel pipes are made of steel ingots or solid billets through perforation to make capillaries, which are then hot-rolled, cold-rolled or cold-drawn. The raw material of carbon Steel Pipe is a round tube blank, which is cut by a cutting machine into a billet with a length of about 1 meter, and sent to a furnace for heating through a conveyor belt. The billets are fed into the furnace and heated at about 1200 degrees Celsius. The fuel is hydrogen or acetylene. Furnace temperature control is a critical issue. After the round tube blank is released from the furnace, it is pierced through a pressure punching machine. Generally, the more common punching machine is the conical roller punching machine. This kind of punching machine has high production efficiency, good product quality, large amount of perforation and diameter expansion, and can wear a variety of steel grades. After perforation, the round tube blank is successively cross-rolled, continuously rolled or extruded by three rolls.
