&#;. The selection principle of mud pump

(1) The mud pump has advantages of high speed, small size, light weight, high efficiency, high fluidity, simple structure, no pulse infusion, stable performance, easy operation and convenient maintenance.

Therefore, in the following exceptions, centrifugal pumps should be used as much as possible: when metering is required, use a metering pump with high lift requirements; when the flow rate is small and there is no suitable small flow high lift centrifugal pump, a reciprocating pump such as cavitation vortex pump can also be used if the requirements are not high.

Select the pump according to high flow, axial and mixed flow. When the viscosity of the medium is greater than 650 to square mm/s, select the rotor pump or the reciprocating pump (gear pump, screw pump). In the case of 75% gas medium, if the flow rate is small and the viscosity is less than 37.4 square mm/s, the vortex pump can be used.

In the case of frequent irrigation pumps or inconvenient guidance, self-priming pumps, self-priming centrifugal pumps, self-priming eddy current pumps, and pneumatic (electric) diaphragm pumps should be used.

(2) Make the model and performance of the selected mud pump meet the requirements of technological parameters such as device flow, lift, pressure, temperature, cavitation flow, and suction range.

(3) The dielectric properties that must be met. For the transportation of flammable, toxic or explosive pump medium, it is necessary to have reliable seals for slurry pumps with no leakage, such as magnetic drive pumps, diaphragm pumps, and canned motor pumps.

For delivery pumps of corrosive media, the convection part requires corrosion-resistant materials, such as stainless steel corrosion pumps AFB, the CQF plastic magnetic drive pumps.

A pump for conveying solid particles containing medium, wear-resistant materials requires a convection section. If necessary, seal and rinse it with the cleaning liquid.

(4) The mechanical design of the mud pump has advantages of high reliability, low noise and small vibration.

(5) Economically, the total cost of equipment, operation, maintenance and management should be considered to be the lowest.

&#;. Selection method for sealing method of the mud pump

During the use of the mud pump, attention should be paid to its sealing technology.

(1) Packing is a common seal. The seal is injected with water in the form of continuous injection water under the pressure in the gasket to prevent the leakage of the mud pump. It is not suitable for the seal of multi-stage shaft seal mud pumps and packing. It has advantages of simple packaging and sealing structure, easy maintenance and low price.

(2) The impeller is sealed by the mud pump. The impeller with the reverse centrifugal generates the acting force to prevent the slurry from leaking out.

When the positive pressure value at the pump inlet is not greater than 10% of the pressure value at the outlet of the mud pump, the first-stage pump of a single-stage pump or a multi-stage pump can be designed with an impeller mechanical shaft seal, which does not dilute the slurry and has a good sealing effect.

Therefore, in the case where dilution is not allowed in the slurry, this method of sealing can be considered.

(3) Mechanical seals of mud pumps generally have relatively high requirements for seals. Especially in some chemical and food fields, not only sealing is required, but it is important not to add additional components to the pump body. The disadvantage is that the mechanical seal of the mud pump is expensive and difficult to maintain.
