Description
Technical field
The present invention relates to a kind of sliding vane pump, particularly a kind of oil-leading stripping pump.
Background technique
China Patent No. is 200510062213.8, notice of authorization day is in the patent documentation on February 20th, 2008, disclosed a kind of double-action connectless sliding vane pump, this sliding vane pump comprises motor, coupling, pump housing assembly, pump housing assembly comprises the stifle that connects successively, pump cover, pump closure, the pump housing, stator, slide plate, rotor, pump shaft, saturating lid, roller assembly, the axle of motor is connected by coupling with pump shaft, slide plate places in the radial groove of rotor slidably, roller assembly is installed at the slide plate two ends, pump closure is equipped with in the pump cover inboard, the roller assembly frame is on the pump closure internal surface, the pump closure internal surface has the molded lines identical with the cross section of described stator interior, and molded lines comprises that two sections are waited the little circular arc of radius, two sections are waited the radius orthodrome, four sections transition curves.This sliding vane pump is owing to utilize the roller assembly that is installed on the pump closure to control the movement locus of slide plate; guaranteeing that the slide plate top does not have directly with stator inner surface contacts; eliminate slide plate and wearing and tearing between the stator and heating in the common sliding vane pump, improved the efficient and the reliability of sliding vane pump.
Yet, above-mentioned double-action connectless sliding vane pump is because pump closure internal surface molded lines is identical with the stator inner surface molded lines, pump closure and stator inner surface have eight molded lines, promptly two are waited radius orthodrome curve, article two, wait the little circular curve of radius, article four, there are eight transition points between the transition curve, rotor is under the high-speed driving of motor, the roller assembly of slide plate both sides is in through eight transition points, advance at stator, the overcurrent region area of outlet correspondence is too little, cause rate of flow of fluid too fast, especially stator import overcurrent zone, rate of flow of fluid is too fast, cause mercury vapour erosion decreased performance, under the oil and gas multiphase flow operating mode, vapour lock and cavitation phenomenons very easily take place in pump, so that can't carry out sweeping operation meeting appearance exciting in various degree and come to nothing, and have so just directly destroyed the micro-gap of setting up by accessory size control between slide plate top and the stator inner surface, cause cavitation performance to descend, pump can not carry out normal oil and gas multiphase flow.
In addition, place slidably in the radial groove of rotor owing to slide plate in the above-mentioned double-action connectless sliding vane pump, both sides pump closure and slide plate two ends and two ends of rotor are tightly assembled, form the friction pair of sealing, drawing oil, under the sweeping working condition, in the gas-liquid, hydrocarbon content and height, friction pair can not get lubricated fully and heat radiation in the long-time running process, can cause " burning dish ", it is pump closure one side, the slide plate both ends of the surface, produce high temperature and adhesion between the two ends of rotor face, especially the friction pair of pump closure one side and slide plate both ends of the surface can destroy fully, cause the slide plate can not be effective, normally do being free to slide in the rotor radial groove, temperature sharply raises in the pump thereby make, and this has not only had a strong impact on the gas-liquid delivery function of pump; Can make pump simultaneously owing to kill, destroy inner body, cause motor to burn out.
Summary of the invention
The objective of the invention is to solve the deficiency of above-mentioned sliding vane pump, and a kind of anti-cavitation performance and anti-vapour lock ability height be provided, operation efficiently, oil-leading stripping pump stably.
Purpose of the present invention is achieved through the following technical solutions: a kind of oil-leading stripping pump, comprise motor, coupling, pump housing assembly, pump housing assembly comprises the pump cover that connects successively, pump closure, the pump housing, stator, slide plate, rotor, pump shaft, roller assembly, the axle of motor is connected by coupling with pump shaft, slide plate places in the radial groove of rotor slippingly, roller assembly is installed in the two ends of slide plate, pump closure is arranged on the inboard of pump cover, be provided with spacing cavity volume in the pump closure, the interior perimeter surface of this spacing cavity volume is the multistage line face of rounding off, roller assembly is set in the spacing cavity volume of pump closure and rolls with the interior perimeter surface of spacing cavity volume and cooperates, it is characterized in that: described inner surface of stator for the corresponding multistage line of the interior perimeter surface face of spacing cavity volume, be connected with concave face between the adjacent multistage line face, be provided with suction port or exhaust port at the concave face place.
Further, described multistage line face includes into two great circle cambered surfaces and two little arc surfaces that become the axle center symmetry of axle center symmetry, link to each other by concave face between the adjacent large and small arc surface in the multistage line face of described stator inner surface, in each adjacent concave face, one concave face place is provided with suction port, and another concave face place is provided with exhaust port.
