fracturing proppant Coefficient of thermal expansion

Advantages of ceramic ball bearings 15.
High temperature
Coefficient of thermal expansion of the ceramic balls, in a high temperature environment because of the temperature does not cause expansion of the ball bearing, thereby greatly enhancing the use of the temperature of the bearing, 
oil fracturing proppantplain bearing temperature of 160 degrees, the ceramic balls can reach 220 degrees Celsius. MA 13-967-37-76-90
High speed
Ceramic balls with oil-free self-lubricating properties, low coefficient of friction ceramic balls, ceramic ball bearings therefore has a high speed, according to statistics with ceramic ball bearings are generally bearing speed 1.5 times more speed.
Ceramic ball can not add any oil, grease means that even kill, acid fracturing bearing still able to operate, thus avoiding the occurrence of fat to get rid of because of premature bearing damage caused by the phenomenon of ordinary bearing. According to our testing and feedback from some of our customers use ceramic ball bearing service life is 2-3 times more common after bearing.
Insulation
Finally and most importantly, insulation, ceramic ball bearings, the bearing can make the insulation between the inner and outer rings, since the ceramic ball insulator between the inner and outer rings of the bearing with ceramic balls, the insulation effect can be achieved. This allows the bearings can be used in a conductive environment. rolling bearing by the rings, rolling elements, retainer, composed grease, seals, when rolling hydraulic fracturing benefits ceramic material, which is defined as the rolling bearing ceramic ball bearings.

fracturing proppant This high degree of standardization bearing

ceramic ball bearings
In the development and application of engineering ceramic products, ceramic ball bearings are a 
typical example of engineering ceramics are widely used in the industrial field, and are highly 
valued in many countries. In the high-speed precision bearings, 
oil fracturing proppant the most widely used hybrid ceramic ball bearings, rolling elements that use hot Si3N4 ceramic ball bearing ring remains rims. This high degree of standardization bearing, structural alterations of the machine is small, easy maintenance, especially suitable for high-speed operation of acid fracturing occasions. Its high-speed spindle assembly, a high-speed, high stiffness, high power, long life and other advantages. A bearing arrangement: inner and outer ring bearing steel / stainless steel + ceramic ball + PA66 / stainless steel retainer +2 RS/ZZ2 high temperature grease, 3 ceramic ball bearings and plain bearings hydraulic fracturing benefits compared advantages:

fracturing proppant Produced by cutting or grinding action

Drilling
Drilling (drilling) is a mechanical device, a cylindrical bore is drilled in the formation of a predetermined depth engineering. By rock crushing manner and the type of tools 
oil fracturing proppant can be divided into Dayton drilling and rotary drilling.
1 Introduction
In geology, the use of underground drilling equipment to drill a smaller diameter, the depth of the larger cylindrical hole, known as drilling. Drilling diameter and depth of sizes, depending on the use of drilling and mineral burial depth. Drilling for oil, gas and groundwater drilling diameters are larger. The main functions are: ① get underground kind of information, that is to take the core, mine heart, debris, liquid sample, such as gaseous samples from the well. ② as geophysical logging channels, access to a variety of rock layers geophysical field data. ③ as an proppant conductivity artificial aquifer hydrogeological observation channel dynamics. ④ used for exploration, mining, developers groundwater, oil and gas, and geothermal drilling.
Drilling usually use is divided into geological survey or exploration drilling, hydrogeological drilling, wells or engineering geology drilling, geothermal drilling, oil drilling, coal drilling, ore field drilling, drilling and other construction ground.
Dayton Drill
Dayton drill, also known as impact drill. Dayton drill with a rope to the bottom, by a power-driven walking beam mechanism, so that one end of the beam moves up and down, and drive up and down the rope and drill generate impact, the rock crushing. Leighton diamond drilling speed is slow, inefficient and unable to meet the increasing depth and drilling requires complex formation, gradually being replaced by rotary drilling. But it has a simple equipment, low cost and no pollution oil, etc., can be used for some low shallow wells, wells dropout.
Rotary drill
Produced by cutting or grinding action of hydraulic fracturing benefitsthe rotating drill bit broken rock. Is the most common methods of drilling. Beaton diamond drill fast, and easy to handle well collapse, blowouts and other complex situations. Press the power transfer mode, rotating the drill can be divided into rotary drilling and downhole drilling two types: rotary drilling device at the wellhead turntable rig, wheel well and the central part of the hole, the drill string side of the square hole through the kelly , then under kelly drill string and drill bit, drill string and drill bit driven when powered turntable rotates together, broken rock. Downhole drilling using downhole drill motor driven drill crushing rock, while drilling the drill string does not rotate, wear, life is short, especially suitable for directional well. Downhole drilling turbo drill, screw drill and electric drilling.
Drilling is the use of downhole drill turbodrill, rotary screw drill and impact drill by drilling fluids driven approach. Characterized footage quickly, WOB small, high pressure pump. Suitable for drilling directional wells or special hard bottom hole section.
Rotary drilling equipment by function into the system, improve the system, mud circulation system. Power and transmission and control systems.
