Problems solved by technology
[0003] In the existing high-pressure small pump set unit shaft distribution device, the main body of the distribution shaft installed inside generally needs to be inspected regularly. The outer casing of the group unit shaft distribution device is mostly fixed by bolts, and there is only one layer of sealing mechanism. After repeated disassembly and assembly, the sealing performance may be poor. When it is used later, oil leakage may occur, which will damage the device. For Insufficiency of the prior art, the present invention discloses a high-pressure small pump set unit shaft flow distribution device to solve the above problems

The invention discloses a unit shaft flow distribution device of a high-pressure small pump set, and relates to the field of high-pressure small pumps. The high-pressure small pump set unit shaft flow distribution device comprises a first pump body shell, a second pump body shell, a secondary sealing assembly and a flow distribution shaft body, the secondary sealing assembly comprises a secondary sealing insertion pipe head, and the secondary sealing insertion pipe head is fixedly connected to the side wall of a second butt joint sealing plate. When the high-pressure small pump set unit shaft flow distribution device is used, the flow distribution shaft main body is conveniently installed in the first pump body shell and the second pump body shell, the first pump body shell and the second pump body shell are convenient to disassemble and assemble, the internal flow distribution shaft main body can be conveniently and regularly checked, and the working efficiency is improved. And after the first pump body shell and the second pump body shell are installed and fixed, secondary sealing is formed at the connector between the first pump body shell and the second pump body shell, the oil leakage phenomenon is not prone to occurring, and therefore it is guaranteed that the device is stable and not prone to damage.
Description
technical field [0001] The invention relates to the technical field of high-pressure small pumps, in particular to a unit shaft flow distribution device of a high-pressure small pump set. Background technique [0002] As a key component of the auxiliary system of the ship, the electro-hydraulic remote control valve mainly drives the pump unit to rotate through the micro motor to realize two-way hydraulic power output to control the working state of the electro-hydraulic remote control valve, and can quickly and accurately grasp the fluid flow and flow rate of the system pipeline and flow and other motion states. [0003] In the existing high-pressure small pump set unit shaft flow distribution device, the main body of the distribution shaft installed inside generally needs to be inspected regularly. The outer casing of the group unit shaft distribution device is mostly fixed by bolts, and there is only one layer of sealing mechanism. After repeated disassembly and assembly,...
