SU983317A1 - Reversive guided-vane pump - Google Patents

Description

  The invention relates to pump engineering, namely to volumetric displacement pumps.

Known reverse gate valve containing; housing with a suction and discharge cavity / stator with a suction channel communicated with the suction cavity of the housing, a rotor with distribution channels placed in the stator with the formation of working chambers and having a groove on its end surface for fixing element rigidly connected to the stator , the disk interacting with the rotor face, opposite to the stator, and the spring-loaded gate 1.

The disadvantage of the known pump is that the installation of a spring-loaded gate on the rotor increases the size of the latter, which reduces the size of the working chambers and reduces. specific pump performance.

The aim of the invention is to increase the specific performance of the pump, as well as improving processability.

This goal is achieved by the fact that a spring-loaded gate is installed in the stator, the distribution channels

the rotor is made in the form of two curvilinear grooves on its opposite end surfaces, and a through groove made on its cylindrical surface, and the disk is provided with a hole arranged to alternately communicate one of the oriental grooves and the through groove with the injection

10 of the housing cavity, with another curvilinear groove communicating with the suction hole of the stator.

In this case, the gate can be made non cylindrical.

Figure 1 shows the pump, longitudinal section i in figure 2 - section AA in figure 1, with the rotation of the eccentric shaft in a clockwise direction; on fig.Z - section BB in figure 1, with the rotation of the eccentric shaft clockwise; figure 4 - section aa in figure 1, while rotating the eccentric shaft counterclockwise, figure 5 - section bb in figure 1 with

2 rotation of the eccentric shaft counterclockwise. .

The reversible vane pump includes a housing 1 with a suction cavity 2 and a discharge cavity 3, an instrument 4 with a suction channel 5 communicating with the suction cavity 2 housing 1, a rotor b placed in the stator 4 to form working chambers 7 and 8 and having a groove 9 on its end surface 10 interacting with the stator 4 for the fixing element 11, rigidly connected with the stator 4, a disk 12 interacting with the end surface 13 of the rotor b opposite to the stator 4, fixed from rotation relative to the stator 4 by the pin 14, gate 15. located in the blind hole 16 of the stator 4 and pressed against the cylindrical surface 17 of the rotor 6 by the spring 18. The rotor b has a curved groove 19 on the end surface 10, communicated alternately with one of the working chambers. 7 or Hang by the suction channel 5 of the stator 4, - a curved groove 20 on the end surface 13 and a through groove 21. on the cylindrical surface 17. The disk 12 has a hole 22, arranged to alternately communicate curved groove 20 on the end surface 13 of the rotor b and a through groove 21 on its cylindrical surface 17c - the pressure cavity 3 of the housing 1. The rotor b is rotatably mounted on an eccentric shaft 23 equipped with a discharge hole 24.

The pump works as follows.

When rotating the eccentric shaft 23 on. clockwise (fit.2 and 3J the rotor b, held from turning by the fixing element 11, makes a planetary movement inside the stator 4. At the same time, the working fluid from the suction cavity 2 of the housing 1 through the suction channel 5 of the stator 4, curvilinear groove 19 on the front surface 10 the rotor 6 enters the working chamber 7, and from the working chamber 8 is displaced through a curved groove 20 on the end surface 13 of the rotor b, the hole 22 of the disk 12, the pressure cavity 3 of the housing 1 and the hole 24 of the eccentric shaft 23 into the discharge line (not shown). a) V By rotating eccentric shaft 23 anticlockwise (Figures 4 and 5) the working liquid from the suction of .losti 2 of the body 1 through the suction channel 5 .statora 4, the curved groove 19 on the end face 10

rotor b enters

working chamber 8, and from the working chamber

Thanks to the placement

The gate on the volume of the working stator increases the output time, which increases the pump flow rate.
