    1. STEAM SEAL OF A PLUNGER PUMP containing a hydraulic unit and a hydraulic unit head with suction and discharge valves installed in it, and which plunger self-centering the slug sleeve, so as to simplify its manufacture and to accommodate it, to simplify its manufacture and to accommodate it, to simplify its manufacture and to accommodate it, and to make it easy to install and place it, and to make it easier to create and place them, to simplify its manufacture and to accommodate them and to accommodate them and to make them easier to install and accommodate them. in operation, it is provided with a pressure ring, which is installed with an axial clearance in the end bore of the pump bushing, which is made in the pump casing, between the end surface of the sealing sleeve and the head of the hydraulic unit, while externally The surface of the pressure ring is made under the groove in which the seal is installed. 2. The slit seal according to claim 1, characterized in that, in order to compensate for large angular displacements, the outer surface of the pressure ring is made spherical.

    专利说明:

    The invention relates to a sealing technique and can be used in plunger pumps. A slit seal of the primary pump plunger is known, including a hydraulic unit and a hydraulic unit head with suction and pressure valves installed therein, a female plunger covering the self-centering sealing sleeve 1J. A disadvantage of the known devices is that it is difficult to manufacture and cannot be used when the pump contains several plungers, since the distance between the individual sealing sleeves can change under the effect of temperature. The aim of the invention is to simplify manufacture and increase reliability of operation. The goal is achieved by the fact that a slit seal of a plunger pump containing a hydraulic unit and a hydraulic unit head With suction and discharge valves installed in it, covering the plunger self-centering sealing sleeve, is equipped with an pressure ring, which is installed with an axial clearance in the end cage that is filled in the pump body the face of the sealing sleeve and the head of the hydraulic block facing the head of the hydro block, while the outer surface of the pressure ring is screwed The seal in which the seal is installed. In this case, the outer surface of the pressure ring is spherical. In FIG. 1 shows a part of the pump, an axial section; in fig. 2 - cut ring, cut; in fig. 3 - variant of the sealing sleeve. Elastically deforming the sealing sleeve 1, the inner diameter of which is larger than the outer diameter of the plunger 2, with its end face located on the suction side A, contacts the pump casing 3, and the other end surface, which is directed to the pressure side B, contacts the pressure member ring 4. The pressure ring 4 is installed in an end groove 5 with an axial clearance 6 in the pump casing. The internal diameter d of the pressure ring 4 is larger than the internal diameter d of the sealing sleeve 1. For mobility sealing sleeve 1 pressure ring 4 is made with a spherical outer surface. On the outer surface of the pressure ring 4 there is a groove 7 in which a seal 8 is installed. The seal 8 installed in the groove 7 is a high-pressure seal. During the injection stroke, the pressure ring 4 is tightly pressed by the pressure medium to the sealing plug 1, which ensures a reliable seal between the pressure side B and the suction side A. In addition, the seal simultaneously presses tightly into the recess 7 and presses against the pump body 3. a low-pressure seal 9 is installed in the pump casing 3. A part of the pump casing 3 with which the end surface of the sealing sleeve 1 contacts, and. the plunger 2 forms a cavity 10 connected by channel 11 to the suction side A. BjjarOflare such an implementation, the liquid that appears in the gap between the plunger 2 and the sealing sleeve 1 and passes into said cavity is diverted back through the channel 11 to the suction side, Eliminate working fluid leaks. Technical and economic: the effectiveness of the invention is to simplify manufacture and increase the reliability of the plunger pump.
