FQW mine pneumatic submersible pump

Introduction of FQW mine pneumatic submersible pump

FQW mine pneumatic the axis of the submersible pump is the basic shaft eccentricity axis section of pump body cavity axis from one eccentricity E, the axis of the eccentricity axis offset section of the basic shaft of eccentricity axis section of the axis of the one from the same eccentricity E, two offset from the value of the flat, as a result, the submersible motor drives the offset a week rotation axis, and the rotor turn only half cycle, that is, the speed of the rotor is half of the submersible motor speed, which is beneficial to extend the piston ring life spans, pump body connection section of discharge decompression chamber cover plate or shell has a shaft hole leakage of fluid water mouth, perhaps shell with mouth water discharge pipe. FQW mine submersible pump rotor submersible pump is a positive displacement pump, has a high power, generally above, has a significant role in electricity saving, energy saving products.

The rotor sleeve and the rotor radial through hole coaxial diameter of the smaller radial hole, radial hole and radial hole made on both sides of the narrow groove connected to the radial hole, constitute the radial flow passage, such a structure, its purpose is to increase the sealing area of the tongue, is conducive to the improvement of volume power and discharge pressure; The pump body cavity is also equipped with a coaxial tongue sheath. The skill plan of FQW mine pneumatic submersible pump is that there are several partitions in the space between the shell of the pump body and the guide plate. The partial pain section of the biased shaft is thrust into the inner sleeve of the rolling bearing and fixed to it. The partial pain section does not wear out, which reduces conflict and heat, and also reduces power consumption.

The tongue sleeve is made of the pump body high pressure area and low pressure area isolation of the tongue; The bias shaft which drives the piston to reciprocate is composed of the base shaft segment and the bias shaft segment, which is directly connected with the extended shaft of the submersible motor. Its partial pain section penetrates into the inner sleeve of the rolling bearing of the piston waist and is fixed to it. The axis of the base axis of the bias shaft has a bias distance E to the axis of the pump body cavity. FQW mine pneumatic submersible pump equipment within the support frame drum, turning the crank and linking to the drum gear, limit and pull the rope, the end of the rise and fall of submersible pump, a brief structure, use of the advantages of convenient, in the fall when the submersible pump will not attack due to fail to handle hurtful situation, can rest halfway through rose submersible pump according to the depth of the water conditioning the depth of the pump, even small カ gas can easily the end of the rise and fall of submersible pump, and motor straight league of rotor eccentricity axis submersible pump, contains suction inlet and outlet of the pump body is installed in the pump cavity and its coaxial rotor and rotor system has at least a row of radial hole, The radial through hole is provided with a piston that can reciprocate by means of the favoritic tissue. The outer circle of the rotor is fixed with a rotor sleeve, the rotor sleeve has a smaller diameter radial hole coaxial with the radial hole of the rotor, both sides of the radial hole are made and the radial hole connected with the narrow slot, constitute the radial flow passage.
