Abstract
The utility model discloses an elastic vacuum rotor pump which is mainly used for pumping and conveying various oil and flammable liquid. An eccentric rotor is arranged in an inner chamber of a pump shell; a blade groove is arranged on the rotor entad; the groove is provided with a spring for propelling blades to cling to the chamber wall of the pump shell in a sliding way; a liquid outlet and a liquid inlet are arranged on the outer wall of the pump shell; one side of the outer wall is provided with a motor shaft connected with the rotor; the other side is provided with a pump cover; the rotor and the blades adopt non-metal material to replace the prior metal material for preparation. The utility model solves the problems that the blades are easy to be blocked when the prior pump pumps the high-viscosity oil and the rotor and the blades rotate and rub to produce sparks when the flammable liquid is conveyed. The utility model has the advantages that the pump chamber forms a vacuum and has good self-absorption performance when the rotor rotates, and no liquid is filled before the operation, and the rotor can have positive and reverse rotation and does not damage the pump, etc.
Description
Technical field
The utility model relates to a kind of elasticity vacuum rotor pump, is mainly used in suction and carries various oil and inflammable liquid.
Background technique
At present, the storehouse is changed in the oil depot oil pumping, the gas station is to automobile fuel filler, factories and miness or open-air construction brigade mechanical work are refueled, and chemical industry unit's inflammable liquid drawing liquid is carried, mostly be to adopt traditional sliding vane centrifugal pump operation, promptly now the main structure of pump is: pump blade is put into blade groove naturally, this groove encloses circle and is arranged off-centre along the cross section disalignment on rotor, blade only throws away by rotor rotation nature during work, with centrifugal action suction oil or inflammable liquid, because blade only slides by knockout press in groove, for the bigger oil of suction viscosity, often stifled card blade and can not working, also have the following disadvantages simultaneously: the one, can only forward rotation, on the contrary then perishable pump; The 2nd, suction capacity is poor, and need add the interior liquid of full pumping before the turn on pump could work; The 3rd, because pump rotor adopts metallic material to make, there is hidden danger in the easy blink that rubs.
Model utility content the purpose of this utility model is exactly for solving above-mentioned deficiency, for people provide a kind of elasticity vacuum rotor pump, it can prevent to aspirate the bigger oil of viscosity effectively and inflammable liquid causes holddown blade, dryness-fire flower, the energy forward and backward, and suction capacity is strong.
The purpose of this utility model realizes by following technical measures:
Comprise pump case, rotor, blade composition, be in the pump case inner chamber, rotor with its axle center off-centre is housed, blade groove is arranged on the rotor, the slidable blade of spring ejection is housed in the groove, and contact is adjacent to pump case chamber wall, and liquid entering hole and liquid outlet are arranged on the pump case outer wall, one side of wall body is equipped with the motor shaft that connects rotor, and opposite side is a pump cover.
Described rotor is a cylindrical body, encloses its circumference and entad has blade groove along cross section circle center line.
Described rotor, blade are that nonmetallic material are made.
Advantage of the present utility model, 1, blade is contained in the rotor upper blade groove, borrows the elastic force of spring to be close to the pump case internal chamber wall, the bigger oil of suction viscosity does not block blade; 2, blade is contained in and adopts entad angle installation in the rotor upper blade groove, and rotor energy forward and backward can not damaged the pump housing; 3, rotor, blade adopt nonmetallic material to make, and have certain elasticity, so good leak tightness, when rotor rotate, pump chamber formed vacuum, and self-priming performance is good, needn't be in pump before working perfusion fluid, can aspirate conveying voluntarily; 4, rotor, blade adopt nonmetallic material, and the rotation friction does not produce spark, carries inflammable, explosive liquid safe reliable.
Description of drawings
