Pulsation dampener is a kind of pressure vessel used to eliminate liquid pressure fluctuation or flow pulsation in the pipeline. It can stabilize fluid pressure and flow, eliminate pipeline vibration, protect downstream instruments and equipment, and increase pump volume efficiency. Two main principles of pulsation dampener 1. Gasbag type: the use the contraction and expansion…

If the whole drilling operation process is compared to human life activities, then the drilling pump, like the human heart, is the source of continuous circulation of drilling fluid from the surface to the bottom of the well, and then from the bottom to the surface. The drilling pump sucks the drilling fluid in the…

Although the quality of small tapered roller bearings are good, the rolling bearing is a precision component, and its use should be carried out carefully. No matter how high-performance bearings are used, if they are not used properly, the expected high performance will not be obtained. The following points should be paid attention to when…

Precision tapered roller bearings mainly include two aspects, one is the dimensional accuracy, the other is the rotational accuracy. The former is required after the bearing is installed. The rotation accuracy is defined as the range of the tolerance of the swing, including the radial and axial swing of the inner and outer rings, the…

The non-metal wear-resistant mud pump is developed by our company according to the users’ construction situation and the performance characteristics of the PN seriesmud pump wear plate in use. The flow passage parts are made of modern non-metallic wear-resistant materials, which have strong wear resistance and cavitation erosion resistance. It is especially suitable for pumping…

The mud pump pony rod is a long and thin rod of pumping well. It is connected to a polished rod on the top and a pump at the bottom to transfer power. The length of a mud pump pony rod is 7.6 or 8 meters. The material is usually high carbon steel, and the surface…
