Abstract

The invention allows to increase the reliability of the pump in a wide range of temperatures. Case 1 with legs 2 installed on the base plate 3 and secured by means of clamping bars 4. In legs 2, samples are made, and on pressure bars 4 are bevels 7, bars are installed in samples with the possibility of contact with legs 2 from bevels 7 the strips 4 and the samples form with the longitudinal axis 5 an angle α defined by the ratio α = B ₁ + B ₂ / 2L, where B ₁ and B ₂ are the distance between the bevels of the front and rear legs 8 and 9, respectively, located along sides of the longitudinal axis 5 of the pump casing

L is the distance between the bevels of the legs, located on one side of the longitudinal axis 5 of the pump casing. Performing the bevels 7 at an angle ensures the movement of the paws 2 when heated along the plane of the bevels, which makes it possible to reliably fix the position of the axis 5 of the housing and get rid of distortions and jamming of the pump impeller in the housing. 4 il.

The invention relates to units for fixed pump housings.

I The purpose of the invention is to increase the reliability of work in a wide range of temperatures.

FIG. 1 shows a mounting assembly for a pump casing; in fig. 2 - view A on 4 | u. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 is a diagram for calculating the angle a.

The assembly of the pump casing contains the casing 1 with the paws 2 and the base plate 3 interconnected by means of clamping strips 4 attached to the base plate 3, and the distances between the paws 2 located on one side of the longitudinal axis 5 of the casing 1 of the pump are the same , in paws 2 samples 6 are made, and on clamping bars 4, bevels 7, bars 4 are installed in samples 6 with the possibility of contact with paws 2 from bevels 7, and the planes of contact of bars 4 and samples 6 form an angle but; limited by the following relation:

de BI and B2 are the distances between the bevels, respectively, of the front 8 and rear 9 paws 2, located on opposite sides of the longitudinal axis 5 of the Kopriyca pump 1;

L is the distance between the bevels of the legs, located on one side of the longitudinal axis 5 of the hornfield.

The device works with;

When the pump is operated (Fig. 4), heated, the body 1 lengthens along the pa value, and also expands in a direction perpendicular to the axis 5, by an amount b; and 1) 2. Since the paws

2 samples 6, and bevels 7 on the clamping bars, the angle xX will determine the mixing of the paws 2 in the direction of the bevels 7, which will preserve the specified position of the axis 5 of the pump casing and eliminate distortions and zaklikvznie impeller . This will allow to increase the reliability of the four-support pump operation in a wide temperature range.

Claims (1)

Invention Formula The assembly of the pump casing, comprising a casing with legs and a base plate, interconnected by means of pressure plates fixed to the base plate, the distances between the legs located on one side of the longitudinal axis of the pump casing being different, differing in that. in order to increase the reliability of work in the rocky temperature range by ensuring the centering of the body when the latter is performed with four-support, samples were made in the paws, and samples were made on the legs; the slats are bevels, slats are installed in the samples with the possibility of contact with the paws from the slant side, and the planes of contact of the slats and samples form with the angle:-: the axis of the pump casing angle;; determined by the following ratio: „YrctaJB -. + B. “. , where BI and Br are the distances between the bevels, respectively, of the front and rear legs, located on opposite sides of the water supply axis; L is the distance between the bevels: iari, located on one side of the longitudinal axis of the pump casing. 6-6 2 Fig.Z .h
