Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0036] like Figure 1-Figure 2 As shown, the double-cylinder eccentric rotary pump consists of middle surface seal 1, rear seal 2, rotor 3, rotor sealing strip 4, internal gear 5, fixed gear 6, crankshaft 7, end cover 8, front seal 9, end cover 10, cylinder Body 11; the double-cylinder eccentric rotary pump has two working chambers, a working cylinder body 11 is clamped between the front seal 9 and the middle face seal 1, and the back seal 2 and the middle face seal 1, and the three are fixed with bolts. Cavities are provided inside the cylinders 11, and rotors 3 are respectively arranged in the cavities. The sides of the rotors 3 and the cavities respectively form working chambers, and the outer end faces of the two cylinders 11 are provided with two inlets and two outlets. , the rotors 3 of the two cylinders are set on the two eccentric parts of the ...

Abstract

The invention discloses a double-cylinder eccentric rotary pump. The double-cylinder eccentric rotary pump comprises a first cylinder body and a second cylinder body. The first cylinder body and the second cylinder body are each internally provided with a cavity. The outer end surface of the first cylinder body and the outer end surface of the second cylinder body are each provided with inlets and outlets. The cavity of the first cylinder body and the cavity of the second cylinder body are internally provided with a first rotor and a second rotor correspondingly. Working cavities are formed between the side surface of the first rotor and the cavity of the first cylinder body as well as between the side surface of the second rotor and the cavity of the second cylinder body correspondingly. The first rotor and the second rotor are installed on a first eccentric part and a second eccentric part of the same crankshaft in a sleeving mode correspondingly so that the working cavities can be increased or decreased and the inlets can communicate with the outlets. The first rotor is in clearance fit with the crankshaft, and the second rotor is in clearance fit with the crankshaft. Fixed gears are fixed to the first cylinder body and the second cylinder body. Teeth or gear rings matched with the fixed gears are arranged in the middle of the first rotor and the middle of the second rotor. The double-cylinder eccentric rotary pump is high in efficiency, user-friendly, convenient to transport, easy to maintain and capable of achieving real-time monitoring and stepless speed adjusting.

Description

technical field [0001] The invention relates to a double-cylinder eccentric rotary water pump and a slurry pump device with an eccentric rotary cylinder as the core component, adjustable flow rate and pump volume, and operable to move. Background technique [0002] At present, pump products on the market include reciprocating pumps, rotary pumps and other main products. Reciprocating pumps rely on pistons, plungers or diaphragms to reciprocate in the pump cylinder to make the working volume in the cylinder alternately increase and decrease to deliver liquid or pressurize it. The flow and pressure of reciprocating pumps have large pulsations, especially single-acting pumps, due to the acceleration of piston movement and the discontinuity of liquid discharge, the pulsations are even greater. It is usually necessary to set up an air chamber on the discharge line (and sometimes on the suction line) to make the flow more uniform. At the same time, the reciprocating pump also ha...
