Abstract
The utility model discloses an electric machine combined plunger pump with high pressure and low noise, which is characterized in that the plunger pump is directly installed on the flange of one end of an electric machine, and the plunger pump and the electric machine are mutually connected to form an integral body. Rotor cylinders are arranged in the radial directions of the rotors of the plunger pump, the number of the rotor cylinders is even, and the rotor cylinders are arranged symmetrically. The rotor cylinders are provided with plunger pairs, and inner curve rings are arranged outside the rotors. The electric machine combined plunger pump with high pressure and low noise has skillful design, simple structure and convenient installation. Since the electric machine combined plunger pump with high pressure and low noise is provided with the specific inner curve rings with even functions, the electric machine combined plunger pump with high pressure and low noise not only solves the pulsating problem of output flow amount, reduces noise, but also effectively improves working pressure. The electric machine combined plunger pump with high pressure and low noise is an ideal plunger pump with high pressure and low noise.
Description
The utility model relates to a kind of plunger pump, particularly motor and the pump housing combined type plunger pump of one each other.
Existing plunger pump mostly is swash plate (or inclined shaft) end flow plunger pump and eccentric circle annulate shaft flow plunger pump greatly.This class plunger pump is because due to the self structure, generally exist following shortcoming: one, the pump housing and power plant are the split setting, have brought inconvenience to installation.Two, suffered fluid power imbalance in rotor and thrust plate (or pintle) work, thereby not only its pressure is difficult to improve, and be affected its working life.Three, output flow has pulsation, and noise is higher.
The utility model is intended to overcome the shortcoming of above-mentioned existence, provide a kind of simple in structure, easy for installation, pressure is high, the pulseless high hush motor combination formula plunger pump of output flow.
The purpose of this utility model is achieved like this: at first, the utility model organically is combined as a whole motor and plunger pump, to dwindle its volume, is convenient to install.Rotor cylinder number with plunger pump is designed to the even number symmetric arrangement simultaneously, and corresponding configuration has the introversion wire loop of the even number effect of specific curves pattern.Like this, guaranteed that on the one hand the suffered fluid power of rotor and distributor keeps balance fully, improved the force-bearing situation of plunger pump key components and parts, simplified its structure, reduced the required precision of processing and assembling.On the other hand, the flow pulsating movement free of output when specific curves also makes plunger pump work, and make pump when high low pressure chamber fluid is changed, suitable precompressed and pre-expanding are arranged, thereby reduced the noise of plunger pump widely.
Secondly, the utility model has adopted the hydrostatic support technology in trunk piston set.Trunk piston set is designed to the CONCENTRIC REDUCER structure, can reduce the contact stress of introversion wire loop like this, reduces the PV value of bearing, thus the working pressure and the working life of effectively having improved pump.
Specific embodiments of the present utility model is by providing in the accompanying drawing:
Fig. 1 is that the utility model cuts open and shows structural representation
Fig. 2 is the structural representation of the utility model I shape roller trunk piston set
Fig. 3 is the structural representation of the utility model roller trunk piston set
Fig. 4 is the structural representation of the utility model introversion wire loop
Below with reference to the accompanying drawings embodiment of the present utility model is elaborated:
High hush motor combination formula plunger pump is made up of motor 1 and plunger pump 2 two-part.Plunger pump 2 is directly installed on the end flange of motor 1, and both are one each other.The rotor 5 that plunger pump 2 mainly is made up of rotor 5, pintle 10, trunk piston set 6, introversion wire loop 7 and the pump housing 8 is sleeved on the pintle 10.In order to prevent both the mutual interlocks and the wearing and tearing of reducing friction, on the endoporus of rotor, be provided with DU bearing sleeve 9.At rotor 5 radially, be provided with rotor cylinder, rotor cylinder is the even number symmetric arrangement.The best when the rotor cylinder number is six, eight and ten.The DU bearing sleeve that also is provided with at the inwall of rotor cylinder is to reduce its wearing and tearing.Trunk piston set 6 is installed in the rotor cylinder.Trunk piston set 6 is the I shape roller structure, also can make the roller-type structure.The trunk piston set of I shape roller structure is an integrated type CONCENTRIC REDUCER structure, and the cylindrical structure of its microcephaly also offers piston ring groove 11, and its major part is that a cylinder grinds symmetrical flat filament, and the centre is equipped with the DU bearing 13 of columniform band hydrostatic support.I shape roller 12 places in the bearing 13.The trunk piston set of roller-type structure also is an integrated type CONCENTRIC REDUCER structure, (see Fig. 3 a), the also cylindrical structure of its microcephaly, and also offer piston ring groove 11, its major part is a cylindrical body, and cylindrical body 14 is arranged in the semi-cylindrical band hydrostatic support DU bearing 15 (Fig. 3 b).
In the outside of rotor 5, be provided with introversion wire loop 7, introversion wire loop 7 usefulness glue or pin are fixed in the pump housing 8.Introversion wire loop 7 can be two act on or four effects.The introversion wire loop of two effects is that (Fig. 4 a) for plane structure oval in the cylindrical; The introversion wire loop of four effects is the plane structure (Fig. 4 b) in four directions in the cylindrical.Pintle 10 is positioned the center of the pump housing 8.Offer the flow window that doubles introversion wire loop effect number and turnover oilhole on pintle, wherein half is the low pressure hole, and second half is a pressure hole, and the low pressure oilhole communicates with oil-sucking hole on the pump housing, and the high pressure oilhole communicates with the high pressure output oil port.
During work, motor 1 is made high speed rotating by the rotor 5 that coupling 3, crosshead shoe 4 drive plunger pump on pintle 10, and the trunk piston set 6 in the rotor cylinder that radially is provided with on the rotor is thrown toward and is pressing introversion wire loop 7 under action of centrifugal force.Trunk piston set 6 is with in the rotor high-speed rotation, and the roller on the trunk piston set moves along introversion wire loop upper curve raceway, passes in and out thereby drive plunger, finishes oil suction and presses oil work, has guaranteed that plunger pump continuously works.
The utility model is skillfully constructed, simple in structure, easy for installation owing to designed specific introversion wire loop, not only solved the problem of output flow pulsation with even number effect, reduced noise, and improved working pressure effectively.Product after tested, its rated working pressure can reach 32mpa, efficient reaches more than 90%, is a kind of the desirable of wide popularizing prospect that have, high hush plunger pump.
