Problems solved by technology

The existing hydraulic control system is realized by mechanically limiting the operating handle of the main control valve group of the anchor winch. This method actually reduces the opening degree of the main control valve spool, causing the main control valve to throttle increase, the system tends to heat up

Embodiment 1

[0019] This embodiment provides a hydraulic control system for anchor windlass with double pressure compensation, its structure is as follows figure 1 As shown, it includes damping plug 1, first adjustable throttle valve 2, pressure compensation valve 3, three-position four-way manual proportional directional valve 4, shuttle valve 5, second adjustable throttle valve 6, relief valve 7 , Double one-way valve group 8, balance valve 9, first pressure compensation pilot valve 10, second pressure compensation pilot valve 11 and two-position three-way manual proportional reversing valve 12. The hydraulic control system also includes a system oil inlet P connected to the system oil source. The system oil inlet P is divided into three routes, the first route is connected to the pressure measuring port MP, and the second route is connected to the first working oil port of the damping plug 1. A is connected, and the third line is connected to the oil inlet A of the pressure compensation...

Abstract

The invention relates to a hydraulic control system with dual-pressure compensation of anchor and mooring equipment. The hydraulic control system comprises a damping plug, wherein the damping plug isprovided with an oil inlet and a working oil hole which communicates with a system oil source; a four-way oil path is integrated in the working oil hole, wherein a first path is connected with a firstadjustable type throttle valve, a second path is connected with a first pressure compensation pilot valve, a third path is connected with a two-position three-way manual proportional reversing valve,and a fourth path is connected with a pressure measuring hole; the first pressure compensation pilot valve communicates with a shuttle valve; the two-position three-way manual proportional reversingvalve is connected with a second pressure compensation pilot valve; the second pressure compensation pilot valve communicates with a shuttle valve; and a pressure compensation valve communicates withthe system oil source. The hydraulic control system has the advantages that normal operation of anchor and mooring equipment can be met, and two different speeds are provided for an anchor gear working condition and a winch working condition of the anchor and mooring equipment, and are quickly switched, so that a throttling and heating phenomenon as a result of a small valve element opening degreeof a master control valve in an existing mechanical limiting way is effectively eliminated.

Description

technical field [0001] The invention relates to an improvement of a hydraulic control system, in particular to a hydraulic control system of an anchor winch with double pressure compensation. Background technique [0002] With the continuous development of the shipbuilding industry, the market has higher and higher requirements for the control of hydraulic anchor winches. The existing anchor winch hydraulic control system needs to control the anchor windlass working condition and the winch working condition, that is, the hydraulic control system needs to meet the requirements of two speed working conditions. The existing hydraulic control system is realized by mechanically limiting the operating handle of the main control valve group of the anchor winch. This method actually reduces the opening degree of the main control valve spool, causing the main control valve to throttle Increased, the system tends to heat up. Contents of the invention [0003] The purpose of the pr...
