High-viscosity fluid pumping equipment controlled by four-way ball valve

Abstract

The invention relates to the technical field of the fluid transportation, in particular to high-viscosity fluid pumping equipment controlled by a four-way ball valve. The equipment is provided with two tank bodies, and an air jet pump and the four-way ball valve are arranged between the tank bodies; a material inlet and a material outlet are respectively provided with a three-way ball valve; compressed air is alternatively fed into the tank bodies to realize switching between positive pressure and negative pressure; the work of discharging materials and sucking materials can be continuously carried out. According to the high-viscosity fluid pumping equipment controlled by the four-way ball valve, which is disclosed by the invention, moving components and materials are prevented from being contacted, easily-abraded elements are omitted, maintenance cost is low, and driving components, such as a motor, are omitted, no damage is caused by no load or overload, and complex high-viscosity fluid can be pumped.

AI Technical Summary

Problems solved by technology

[0002] The original pumping equipment for high-viscosity fluids is mainly vane or volumetric pumps such as mud pumps, mortar pumps, slurry pumps, diaphragm pumps, plunger pumps, and screw pumps. These pumps have some defects in practical applications. make its application limited

[0003] Slurry pumps, mortar pumps and slurry pumps are vane-type centrifugal pumps. When pumping highly viscous materials and the liquid level is low, the material will not flow in time due to poor material fluidity, which will cause the equipment to suck air and cause no-load work. In severe cases Can damage the pump and motor

When pumping materials containing impurities such as plastic bags, cloth or large-grained solids, the blades will be difficult to rotate or stop due to winding and blocking the cavity, resulting in overloading of the equipment, and in severe cases, overloading and damage to the motor. The principle also determines that it cannot pump pure granular and low water content materials

[0004] Diaphragm pumps, plunger pumps and screw pumps are all positive displacement pumps. During work, there will be moving parts in contact with materials, causing wear and tear, and the repair and maintenance costs are high.

Moreover, due to the sealing form of the one-way valve used in the diaphragm pump and the plunger pump, the sealing of the one-way valve will fail when pumping granular fluid, resulting in the failure of the equipment to work, and the working principle of the screw pump determines that it cannot pump large particles. fluid
