Needle roller, also known as needle cylinder. A metal cylinder with steel needles planted on the surface. It is installed in the drafting zone for controlling and carding fibers. It is used on spun silk and wool spinning roving frame, carded wool spinning frame, spun spinning and shaft spinning frame. The main body of the needle roller is a copper cylinder with small holes drilled on the surface and steel needles are planted in the holes. Both ends of the cylinder are equipped with a flange, the surface of which is slightly higher than the needle tip to protect the needle tip from damage. The main parameters of the needle roller are: bottom diameter, outer diameter, needle width, needle height, needle density, needle angle and needle number. In order to adapt to the processing of different types of fibers, the small carding roller on the rotor spinning machine has the saw teeth replaced with needles, also called needle rollers.

Gear pump in the pump body is equipped with a pair of rotary gear, an active, a passive, relying on the two gear meshing with each other, the entire pump cavity divided into two independent parts. A for the inhalation chamber, B for the discharge chamber. When the gear oil pump is in operation, the driving gear drives the driven gear to rotate. When the gear meshes and disengages, a partial vacuum is formed on the suction side (A) and the liquid is sucked in. The sucked fluid fills each tooth valley of the gear to the discharge side (B), and the liquid is forced out when the gear enters into engagement to form a high-pressure liquid which is discharged outside the pump through the pump discharge port.
Gear pump features 1. Compact, easy to use and maintain.
2. Has a good self-absorption, so every time you open the pump without filling the liquid.
3. Gear pump lubrication is delivered by the liquid automatically reached, so do not have to add daily oil lubrication.
Gear pump is widely used in petroleum, chemical, shipbuilding, electric power, grain and oil, food, medical, building materials, metallurgy and national defense research and other industries. Gear pump for conveying solid particles and fibers do not contain, non-corrosive, the temperature is not higher than 150 ℃, the viscosity of 5 ~ 1500cst of lubricating oil or other properties of similar lubricants liquid. Try all kinds of room temperature freezing and freezing in the outdoor installation and process requirements of the insulation process.
