Problems solved by technology

Its defects are as follows: 1. When the plunger pump is working, it will first use part of its own power to transport oil to its own pump for lubrication, which increases the load power of the motor. The corresponding position is equipped with a supply oil tank and corresponding oil pipelines, which increases the amount of product processing and assembly, and prolongs the production cycle; 2. Each hydraulic steering gear needs to be equipped with two upper-mounted AC hydraulic workstations and one supply oil tank , not only the weight of the product is greatly increased, the cost of the product is significantly increased, but also the total area of ​​the installation space on the ship is significantly larger

Abstract

The invention relates to the field of hydraulic systems, and particularly relates to an underneath type double-pump alternating current hydraulic working station for a hydraulic steering engine. The underneath type double-pump alternating current hydraulic working station mainly comprises an engine seat, an oil tank, a special steering engine valve set, a first motor pump set, a second motor pump set, a first oil suction opening and a second oil suction opening, wherein the first motor pump set and the second motor pump set are arranged on the engine seat below the oil tank; the first motor pump set is connected with the oil tank through the first oil suction opening; the second motor pump set is connected with the oil tank through the second oil suction opening; and the special steering engine valve set is connected with the first motor pump set and the second motor pump set respectively. According to the embodiment of the invention, the alternating current hydraulic working station has a relatively compact structure, so that only one oil tank is needed, and the conventional complementation oil tank is eliminated; and therefore, the steel materials are saved by 45 percent, and the cost of a product is saved greatly.

Description

technical field [0001] The invention belongs to the field of hydraulic systems, and in particular relates to a double-pump type AC hydraulic workstation with a hydraulic steering gear under it. Background technique [0002] The motor and plunger pump in the hydraulic workstation of the original hydraulic steering gear are placed on the uppermost part of the fuel tank, which is the upper horizontal type, and a hydraulic workstation is equipped with a group of motor pumps, which are combined with the fuel tank. Its defects are as follows: 1. When the plunger pump is working, it will first use part of its own power to transport oil to its own pump for lubrication, which increases the load power of the motor. The corresponding position is equipped with a supply oil tank and corresponding oil pipelines, which increases the amount of product processing and assembly, and prolongs the production cycle; 2. Each hydraulic steering gear needs to be equipped with two upper-mounted AC ...
