Description
Technical field
The utility model relates to the pump technical field, is a kind of rotary piston pump specifically.
Background technique
Existing rotary piston pump, as conical ring plate or sinusoidal wave ring plate rotating piston pump, the rotating cam of one of its core component is not considered the dynamic balancing of himself, pump is when running up, rotating cam impacts very big to another core component baffle assembly, noise is big, and makes pump housing heating.There is structural imperfection in existing baffle assembly, and not only noise is big, has also limited the pressure and the flow of pump.In addition, existing mechanical seal closure radiating effect is poor, and cover temperature height has a strong impact on the stream time of pump.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of simple in structure, cost is low, efficient is high, noise is little, suction capacity is strong, the rotary piston pump of long service life.
The technological scheme that its technical problem that solves the utility model adopts is: rotary piston pump is made up of pump shaft 1, mechanical seal 2, bearing 3, the pump housing 4, rotating cam 5, central diaphragm 6, baffle assembly 7, cartridge housing 8, end cap 9, mechanical seal cover 10 and radiating fin 17.Rotating cam 5 has two, and the side of each cam all has the compensating groove 18 that several degree of depth do not wait, and makes rotating cam 5 self reach dynamic balancing when rotated, two rotating cams 5 assemble in opposite directions, 180 ° of convex surface mutual dislocation are fixed on the pump shaft 1, form spin friction with the pump housing 4 endoporus.Central diaphragm 6 is positioned in the middle of two rotating cams 5, has the wedge shape hollow cavity on it, forms left and right sides work chamber jointly with the convex-concave waveform curved surface of rotating cam 5.Central diaphragm 6 tops have the opening slot that parallels to the axis, and baffle assembly 7 is housed in the groove.Mechanical seal 2 and mechanical seal cover 10 are contained in pump shaft 1 power end.Baffle assembly 7 is made up of baffle plate body 11, slide block 12, spring 13, pivot pin 14, guide pin bushing 15 and guide pillar 16.Baffle plate body 11 is fixed in the chute of central diaphragm 6, and the oil suction and the oil extraction work of pump are finished in slide block 12 to-and-fro motion under the effect of spring 13 and rotating cam 5 arc shaped surfaces.Each slide block 12 is rolling friction with rotating cam 5 arc shaped surfaces, is equipped with pivot pin 14 in the middle of each spring 13, when slide block 12 to-and-fro motion, spring 13 is play the guiding role, and prevents the spring clamping stagnation and fractures.Mechanical seal cover 10 is provided with radiating fin 17, in time distributes the heat that mechanical seal 2 produces, and avoids the pump housing overheated.
The beneficial effects of the utility model are: simple in structure, reliable performance, cost is low, efficient is high, noise is little, and suction capacity is strong, long service life, but forward is carried and also can oppositely be carried.
