Background
In oil and gas field development, a fracturing technology is widely used for yield increasing construction, wherein the most main equipment in the fracturing construction is a fracturing pump, the fracturing pump comprises a power end and a hydraulic end, the power end converts diesel engine or motor energy into kinetic energy and transmits the kinetic energy to the hydraulic end through a plunger, and a main component of the hydraulic end is a valve box; when the fracturing pump valve box is in the normal working process of the fracturing pump, the abrasion of the fracturing pump valve box is quick, the fracturing pump valve box can be frequently assembled and disassembled for replacement, in the reinstallation process of the fracturing pump valve box, the accurate positioning and the quick installation of the fracturing pump valve box relative to a frame not only determine the important criterion of whether the whole fracturing pump can work normally, but also the abnormal abrasion of the valve box and a plunger packing can be effectively avoided by the accurate installation of the valve box. So the fracturing pump valve box adjusting and supporting device not only provides accurate and reliable installation positions for the fracturing pump valve box, but also has convenient adjustment and is very favorable for quick replacement of the wearing fracturing pump valve box.
At present, most of the traditional fracturing pumps adopt stud bolts to directly connect a valve box with a rack, and the valve box is directly hung at one end of the stud bolts, so that in the working process of the fracturing pump, the whole valve box and all the weight of internal parts of the valve box are difficult to effectively support only by the stud bolts, and the stud bolts are often bent, deformed and even broken. Secondly, in normal working process of the fracturing pump, along with vibration of the fracturing pump, the valve box also generates larger vibration, if the valve box is not firmly installed, abnormal abrasion of plunger packing and small connecting rod packing of the valve box is caused if the installation position of the valve box relative to the frame is changed, ablation of a cross head and a slideway of the fracturing pump is also caused when the valve box is severe, and the whole fracturing pump is directly caused to be incapable of working. Third, because the fracturing pump valve box needs to bear fracturing sand-carrying fluid high pressure and high flow rate flushing in the working process, after the normal service life of the valve box (usually hundreds of hours), the worn fracturing pump valve box needs to be replaced, in the replacement process, the repositioning and the installation of the valve box are important technical indexes of the maintenance quality of the fracturing pump, and the rapid and efficient replacement of the fracturing pump valve box can directly affect the integral use of the fracturing pump.
