Relying on the rotational motion of the cam, the rotor is driven to rotate inside the pump body. The chamber between the rotor and the pump body changes periodically as the rotor rotates, thus sucking in and discharging the emulsion explosive matrix.
Pump Body: Usually made of high-strength and corrosion-resistant materials such as cast steel and stainless steel to ensure the tightness and durability of the pump body. It can withstand the high viscosity of the emulsion explosive matrix and the pressure during the transportation process.
Cam: It is the core component of the pump, generally made of steel with high hardness, having good wear resistance and strength. The shape and size design of the cam directly affect the transportation performance and flow characteristics of the pump.
Rotor: Cooperates with the cam and rotates inside the pump body. The rotor has various structural forms, commonly including gear type, screw type, etc. Its surface is usually specially treated to reduce friction with the pump body and the matrix.
Sealing Device: High-performance sealing materials such as fluororubber and polytetrafluoroethylene are used to prevent the leakage of the emulsion explosive matrix and ensure the safety and stability of the transportation process. The sealing device usually includes parts such as shaft seals and pump cover seals.
Drive Device: Generally composed of a motor, a reducer, etc., it provides power for the rotation of the cam and the rotor. The power and speed of the drive device are selected according to the transportation flow rate and pressure requirements of the pump. Technologies such as variable frequency speed regulation can be adopted to achieve precise control of the transportation volume.
Smooth Transportation: The cooperation between the cam and the rotor enables the matrix to flow continuously and stably without pulses or vibrations during the transportation process. This helps to avoid problems such as sedimentation, stratification, or bubble bursting of the emulsion explosive matrix during transportation, ensuring the stable performance of the explosive.
Strong Self - priming Ability: It can quickly suck in the emulsion explosive matrix during startup without the need for additional vacuum - pumping equipment, improving the startup efficiency and reliability of the equipment. It is suitable for different installation heights and transportation distances.
Wide Adaptability: It can adapt to the characteristics of the emulsion explosive matrix with high viscosity and high solid content. It has a good transportation effect on emulsion explosive matrices produced by different formulas and processes. At the same time, it can also adapt to a certain extent to the changes in the viscosity and flow rate of the matrix during the transportation process.
Easy Maintenance: The structure is relatively simple, and the disassembly and installation of components are relatively convenient, facilitating daily inspection, repair, and maintenance. This reduces the equipment downtime and improves production efficiency.
It is mainly applied in the production process of emulsion explosives, including transporting the emulsion explosive matrix prepared in the emulsifier to subsequent equipment such as sensitizing equipment, storage tanks, or charging machines. In the on - site mixed loading of emulsion explosives operations, it is also used to transport the matrix in the storage tank to the mixed loading vehicle or blast holes, etc.
