Working Principle and Product Performance of Centrifugal Mud Pump
In the water pump industry, there is a centrifugal mud pump. But in fact, from the physical principle, the mud pump itself belongs to a kind of centrifugal pump, and centrifugal mud pump from the industry interpretation, usually refers to: It is a kind of machinery that through the use of centrifugal force (the rotation…
Introduction of Bearing Roller Tapered
Bearing roller tapered mainly bears radial and axial combined load. The bearing capacity depends on the raceway angle of the outer ring. With larger angle comes greater bearing capacity. This kind of bearing belongs to separate type bearing, which can be divided into single-row, double-row and four-row bearing roller tapered according to the number of…
Selection Code for Valves
In the mud pump, the mud pump valve is the control element, and its main function is to isolate the equipment and pipeline system, regulate the flow, prevent backflow, adjust and discharge pressure. The valve can be used to control the flow of air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive…
Why are Still Pulses There with the Pulsation Dampeners Installed
The metering pump will produce pipeline pulse in the process of operation.In order to eliminate the pipeline pulse, it is necessary to install pulsation dampeners to achieve good results. Recently, many friends met a problem that metering pump installed with the pulse damper will still have pipeline pulse generation. DEZHOU RUNDONG PETROLEUM MACHINERY CO., LTD…
Knowledge about Mud Pump Accessories
The mud pump is a reciprocating piston pump, which is composed of many accessories. Today we will look at two of its main components. 1. The mud pump accessory—air chamber. The air chamber of the mud pump is one of the main mud pump accessories in the discharge end, which is installed at the discharge pipe…
Some Problems in Bearing Roller Tapered Device
Bearing roller tapered are generally separable, that is, cone assembly, consisting of the inner ring with roller and cage assembly, can be mounted separately from the cup (outer ring). Bearing roller tapered is widely used in many industries such as automobiles, rolling mills, mining, metallurgy and plastic machinery. The secondary reason of scratches of the bearing…

Working Principles of Drilling Mud Pump
To make it more clear the function of mud pump, let’s learn how drilling mud pump works. Drilling mud pump is an indispensable corollary equipment of drilling machinery in oil field to transfer mud and water to drill pipe so as to cool and wash drill bit and soil. Oil drilling mud pump is a positive…
Common Causes and Solutions of Hydraulic Cylinder Piston Rod Stick-slip Phenomenon
Common causes of the hydraulic cylinder piston rod stick-slip phenomenon: 1. Coaxiality error In the hydraulic cylinder, coaxiality error could result in the unstable running speed of the cylinder. 2. Components manufacturing precision The manufacturing precision in the hydraulic cylinder inside wall and piston rod surface have serious impacts on the stability of the hydraulic…
