Single screw pump
structure:
The single-headed male screw rotor rotates eccentrically within a special double-headed female screw stator (the stator is soft), swings back and forth along the pump centerline, and remains engaged with the stator.
Features:
1, can transport liquid containing solid particles
2, almost any viscosity of the fluid, especially for high viscosity and non-Newtonian fluid
3, the working temperature is limited by the stator material
Performance parameters:
Flow up to 150m3 / h, pressure up to 20MPa
Application:
For molasses, pulp, starch paste, chocolate pulp, paint, tar, paraffin, grease, mud, clay, clay and so on.
Twin screw pump structure:
There are two the same size of the screw shaft, a drive shaft, a driven shaft, through the gear drive to achieve synchronous rotation.
Features:
1, Screw and pump body, as well as between the screw to maintain 0.05 ~ 0.15mm gap, wear small, long life
2, stuffing box only by the suction pressure less leakage
3, compared with the three screw pump, the impurity is not sensitive
Performance parameters:
The pressure is generally about 1.4MPa, viscous liquid maximum of 7 MPa, the viscosity of the liquid up to 3 MPa, the flow is generally 6 ~ 600m3 / h, the maximum 1600 m3 / h
Liquid viscosity can not exceed 1500mm2 / s
Application:
For lubricating oil, grease, crude oil, asphalt, fuel oil and other high viscosity oil.
Three screw pump
Structure: It consists of an active screw rod and two driven screw rods engaged with it.
Features:
1, the active screw directly driven driven screw, without gear, the structure is simple
2, the pump itself as a screw bearing, no need to install radial bearings
3, the screw does not withstand the bending load, can be made very long, so high pressure can be obtained
4, should not be transported with more than 600μm solid impurities in the liquid
5, high-speed operation, is a small high-flow pump, high volumetric efficiency
6, stuffing box connected only with suction pressure, less leakage
Performance parameters:
Pressure up to 70 MPa, flow up to 2000m3 / h. Suitable viscosity of 5 ~ 250 mm2 / s medium.
Application:
Suitable for transporting lubricating oil, heavy oil, light oil and crude oil. Can also be used for glycerol and viscose and other highly viscous liquid delivery.
The PDC cutters (polycrystalline diamond compact) are made of diamond powder and tungsten carbide substrate sintered under ultra-high pressure and high temperature conditions. It not only has the high hardness, high wear resistance and thermal conductivity of diamond, but also has the strength and impact toughness of tungsten carbide. PDC cutter is an ideal material for manufacturing drilling bits and other wear-resistant tools. Widely used in oil drilling, water well drilling geological exploration, coal drilling and mining PDC drill bits and machining tools and other industries. We can supply PDC cutters for coal mining and geological with 0804, 0808, 1004, 1008, 1304, 1308, PDC cutters for oil exploration PDC Bit size with 1308, 1313, 1613, 1616, 1913 etc. Except for PDC drill bit cutter PDC cutters, we also supply PDC cutter with step shank, they are design for saw balde and use for stone cutting application, we can supply step chain saw PDC cutters with 0808, 1308, 1313 and customized sizes. All these we mentioned is 100% new PDC cutters, we also supply scrap PDC cutters and used PDC cutters, welcome to contact us if you want to know the PDC cutter price or need our help.
