Abstract
A machine pump sealing structure comprises a stationary ring, a moving ring, a spring, a spring seat and a shaft sleeve, and is characterized in that the stationary ring, the moving ring, the spring and the spring seat are sequentially sleeved on the shaft sleeve. The shaft sleeve is provided with a step abutting against the spring seat. The parameters of the spring are as follows: the length is 15 mm+/-1.5 mm, the wire diameter is 3 mm+/-0.5 mm, two circles to three circles, and the compression amount is 9 mm+/- 1 mm. Compared with the prior art, the machine pump sealing structure greatly reduces material leakage and mechanical seal burning on the premise of guaranteeing the sealing.
Description
Technical field
The utility model belongs to pump shaft sealing structure field, specifically is a kind of pump sealing configuration.
Background technique
Mechanical end face seal is that you obtain sealing and axial rotating sealing device by elastic element to pretension and compressing of pressure medium and elastic element pressure quiet, rotating ring end-face friction pair with this.The seal point of mechanical seal mainly is the sealing between rotating ring end face and the stationary ring end face.In the prior art, some chemical industry transfer pumps, being in operation is to seal material by mechanical seal.But along with use, material and burning machine envelope phenomenon appear leaking in pump.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the utility model proposes a kind of new pump sealing configuration, concrete technological scheme is as follows:
A kind of pump sealing configuration comprises stationary ring, rotating ring, spring, spring seat and axle sleeve; Described stationary ring, rotating ring, spring and spring seat are sleeved on the axle sleeve successively; Axle sleeve is provided with step, and step props up spring seat; The parameter that it is characterized in that described spring is: length 15mm ± 1.5mm, and line footpath 3mm ± 0.5mm, two circles～three circles, decrement is 9mm ± 1mm.
The preferred parameter of described spring is: length 15mm, and line footpath 3mm, three circles, decrement is 9mm.
Compared with prior art, the utility model leaks material and burning machine envelope phenomenon and significantly reduces under the prerequisite that guarantees sealing.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an assembling explosive view of the present utility model.
Among the figure, 1, axle sleeve, 2, spring seat, 3, rotating ring, 4, stationary ring, 5, spring, 6, processing place of axle sleeve step.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment:
A kind of pump sealing configuration comprises stationary ring, rotating ring, spring, spring seat and axle sleeve; Described stationary ring, rotating ring, spring and spring seat are sleeved on the axle sleeve successively; Axle sleeve is provided with step, and step props up spring seat.
In this example, the parameter of described spring is: length 15mm, and line footpath 3mm, three circles, decrement is 9mm.
The utility model is that the axle sleeve stepped portions of standard piece is processed, tried out the spring that shortens simultaneously, adjusts the sealing compensation position repeatedly, changes the decrement of spring.The processing of axle sleeve step makes it further to shorten 5mm, and total compression distance is increased, and partly makes original spring 3 circles into 3 circles and increases decrement.
Claims (2)
1. a pump sealing configuration comprises stationary ring, rotating ring, spring, spring seat and axle sleeve, it is characterized in that described stationary ring, rotating ring, spring and spring seat are sleeved on the axle sleeve successively; Axle sleeve is provided with step, and step props up spring seat;
The parameter that it is characterized in that described spring is: length 15mm ± 1.5mm, and line footpath 3mm ± 0.5mm, two circles～three circles, decrement is 9mm ± 1mm.
2. pump sealing configuration according to claim 1 is characterized in that the preferred parameter of described spring is: length 15mm, and line footpath 3mm, three circles, decrement is 9mm.
