Cementing equipment usually refers to the joint operation of multiple special equipments required to complete cementing. There is a major need for a grey car (for transporting dry cement), a tanker (for storing and transporting clean water), a cementing truck (for injecting cement slurry into the well), technical casing and production casing. In the cementing operation, it is sometimes necessary to increase the pressure fan truck (to provide compressed air to the down ash car to increase the down ash speed of the next ash car) and the water supply car (to provide cement water to the cement truck) according to the actual situation. Wells and rail cars (for joint operation of multiple cementing trucks) and spare cars (mainly cementing trucks to prevent malfunction of equipment during operation, resulting in stoppage of operations), sometimes depending on equipment capacity Special equipment used for mixing pulp, such as a pulper (skid) or a multiple-mixer. From the above, it can be seen that there are many types of equipment requirements for cementing operations. However, the work of injecting cement slurry into the well is entirely dependent on the cement truck. Cementing cement truck is a cementing device automatically controlled by computer. It is a high-performance automatic mixing grouting set integrating mechanical system, automatic control system and hydraulic system. The monitoring of cement density and saturation can be completed, and the automatic recording and preservation of construction parameters can be achieved. It provides great convenience for construction. Cementing trucks, just like other commonly used mechanical vehicles, can complete related operations with just one person. Cementing cement trucks are composed of two types of automobile chassis, diesel engines, gearboxes, three-cylinder piston pumps, gear pumps, water tanks, and high and low pressure manifolds. Cementing truck cementing process is usually completed as follows, the lower ash funnel and the mixer connected and fixed, and connect the appropriate pipeline. The next gray car injects ash into the lower ash funnel, filling the lower ash funnel with dry cement. The mixer is usually located in the lower part of the lower ash funnel and this process is accomplished by gravity. And then like the next back to the funnel into a certain pressure of water. When the flow rate of clear water is accelerated, the clear water will drive the dry cement forward. And through the flow of clear water and the action of pipelines, fresh water and dry cement are quickly mixed. The high-speed movement of water forms a spiral of cement in the pipeline and in the course of continuous movement, all kinds of large pieces of cement are broken evenly. The mixed water and dry cement form a cement slurry and are transported to the mixing tank. After the pressure is transferred to the well. The slurry mixing process of ordinary cementing trucks is very simple, and is completely realized by the gear pump system installed in the vehicle. The mixing effect and the ability to treat dry cement are also determined mainly by the capacity of the gear pump. But the biggest problem is the inability to control mud density and the ability to handle dry cement. Cementing vehicles have a wide range of uses in life, and cementing operations also involve many fields at the same time. Especially in the construction of bridges and houses, it is extremely urgent to produce more efficient cementing vehicles and improve their ability to handle cement or other materials.
Lifting Slings/Lifting Sling/ Lifting Belt /Lifting Strap are usually made of either polyester or nylon materials.
There are two kinds of slings which are widely-used.They are flat Webbing Sling and Round Sling .
Flat webbing sling has loops on both ends,and its length ranges from 1 meter to even 50 meters.
Round sling is like a circle,it does not have any loop.
Both webbing sling and round sling has strong strength,or we call it lifting capacity,normally ranges from 1Ton to 15Ton.
And there are 4:1,5:1,6:1,7:1 even 8:1 safety factors.The higher the safety factor is,the stronger the sling is.
