The type of mud pump is varied and its application range is very wide. Many buyers face various kinds of pumps in the market when they buy mud pumps. They often don't know how to make decisions. Below, as a professional oil drilling mud pump manufacturer, we have talked about the basic and specific methods of mud pump selection.
According to the basis of pump selection, according to the technological process and water supply and drainage requirements, it should be considered from five aspects: liquid delivery volume, device head, liquid property, pipeline layout and operation conditions.
1.Flow is one of the important performance data of the pump, which is directly related to the production capacity and transport capacity of the whole device. If the design institute process design can calculate the pump normal, minimum, maximum three kinds of flow. When the pump is selected, the maximum flow is based on the normal flow. When there is no maximum flow, it is usually advisable to use 1.1 times the normal flow as the maximum flow.
2.The lift required by the device system is another important performance data of the pump selection. Generally, the selection of the lift is to be selected with a magnification of 5% - 10%.
3.Liquid properties, including the name of the liquid medium, physical properties, chemical properties and other physical properties of a temperature C density D, the viscosity u, medium diameter of solid particles and gas content, which involves the system's head type, effective cavitation margin calculation and the right pump: chemical properties, mainly refers to the chemical corrosion liquid medium and toxic, pumps are selected materials and use is a major basis seal.
4.Pipeline layout conditions of equipment system refers to send high fluid delivery fluid delivery fluid from toward the suction side such as the minimum level, the highest level from the side, some data and specifications and the length of pipe, pipe materials, specifications, quantity, check for line comb head calculation and NPSH.
5.There are many contents of operation conditions, such as liquid operation, T saturated steam force P, suction side pressure PS (absolute), discharge side container pressure PZ, altitude and ambient temperature operation. Is the gap continuous or continuous, and the location of the pump is fixed or removable.
