Abstract

The utility model relates to a rotor of a roller type rotor pump, which is a key component of a roller pump. The utility model can be used for chemical industry, food industry, medicinal industry, petroleum industry, liquefying gas industry, etc., and is especially suitable for conveying a medium with high corrosiveness and high viscosity. The utility model is formed by that a rotor with a roller groove, and a shaft are integrated into one unit, and the roller is matched with the roller groove. A liquid inlet groove is arranged on the rotor, the liquid inlet groove is arranged at a front position of roller movement, and the liquid inlet groove is communicated with the roller groove. Because of the existence of the liquid inlet groove, the roller is appressed with the inner wall of a pump body to move under the action of medium pressure and centrifugal force by, the output pressure and the flow rate of a pump is increased, and the stabile operation can be realized.

Description

The rotor of roller type rotor pump

The utility model relates to a kind of critical component of roller type rotor pump, particularly can be widely used in the industries such as chemical industry, food, medicine, oil, liquid gas, especially be suitable for the rotor that the roller type rotor pump of highly corrosive, high viscosity medium conveying is arranged to various.

The CN87209851 patent also provides a kind of roller pump, but because of its flow, the big or small unstable use that influences of pressure.

The purpose of this utility model is to provide a kind of rotor of roller type rotor pump, with pump housing cooperating, can improve the delivery pressure and the flow of pump, and can smooth working.

The utility model is achieved in that the rotor of roller type rotor pump is linked into an integrated entity by rotor that has roller slot and axle, and roller cooperate with roller slot form, have lead channel on the described rotor, lead channel and communicates with roller slot on the anterior position of roller motion.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

Identical cylindrical in roller (1), (1) ', (1) " be length and rotor (2), (2) '.

Solid or the hollow cylinder that roller (1) is made into by metal or engineering plastics, roller (1) ' inner core be the metal cartridge of band dovetail annular groove, peripherally be shaped, and there is blind hole at two ends by the engineering plastics coating and injection moulding.

Roller (1) " to make by engineering plastics, the centre is a cavity, the two ends drive fit is silently foraminate in the middle of being made by engineering plastics, fills with lubricating grease in the cavity.Roller (1) " the automatic trace of lubricating grease overflows outside the aperture in when work chamber, reaches self oiling roller (1) " purpose at two ends.

Rotor (2) links into an integrated entity as shown in Figure 1, 2, 3 rotor (2) with axle (3) by key (4) ' make integral body as shown in Figure 5 with axle.

Rotor (2), (2) ' radially be evenly equipped with more than 3 and 3 opening slot be roller slot (5), (5) ' as Fig. 3, shown in Figure 56 roller slots are arranged.And respectively with 6 rollers (1), (1) ', (1) " the identical and loose fit of length, roller can be in roller slot (5), (5) ' in freely rotate and moving along trough roller.Have an arc notch up to roller slot (5), (5) in rotor (2), (2) on the neutral position on the front openings trough rim of the sense of rotation ' be roller slot (5), (5) ' limit ' the bottom be lead channel (6).

Rotor (2) go up the center of roller slot (5) and rotor (2) center on same straight line as Fig. 1, Fig. 2, shown in Figure 3.

The center of rotor (2) ' go up roller slot (5) ' lags behind rotor (2) ' center β=1～30 is ° as shown in Figure 5.

Roller (1) is placed in the roller slot (5) on the rotor (2), will puts into rotor with the rotor (2) of roller (1) again, in the pump housing of pump, connect, be assembled into the roller type rotor pump as shown in Figure 8.Connect with the mains, rotor (2) rotates from the liquid entering hole (8) of the pump housing and enters medium, because of roller slot (5) has lead channel (6) in operation the place ahead, make the bottom of the medium in the place ahead by lead channel (6) introducing roller (1), make roller (1) under pressure medium and action of centrifugal force, be close to the inwall motion of the pump housing all the time, thereby realize suction, row's work of pump.When roller (1) runs near the liquid outlet (9) of the pump housing, introduce the effect of pressure medium by lead channel (6), roller (1) backside pressure is raise, avoid roller (1) to be broken away from the pump chamber inwall by liquid outlet (9) pressure effect.

The utility model is compared with prior art: because of at epitrochanterian roller slot place, towards the rotor rotation direction Front openings one side has increased lead channel, makes so the interior roller of roller slot be close to all the time the inwall motion of the pump housing, Thereby increased substantially output pressure and the flow of pump, and the energy steady operation, be specially adapted to various height and glue The conveying of degree, high-corrosion medium.
