An experimental device for simulating seawater pressure energy operation equipment

Abstract

The invention belongs to the field of marine ships and discloses an experimental device for simulating seawater pressure energy operation equipment. The device includes a gear pump, a variable motor and a quantitative pump. The gear pump sucks oil from the oil tank and gives pressure to simulate high-pressure seawater entering the variable motor; the variable motor uses the oil pressure difference between the inlet and outlet to drive the quantitative pump to simulate the pressure of seawater. Seawater pressure is used to drive the load; the quantitative pump sucks oil from the oil tank, so that the oil circulates in the quantitative pump and the oil tank, thereby simulating the load; the overflow valve adjusts the pressure between the gear pump and the variable motor, simulating seawater pressure at different depths ; The proportional pressure valve adjusts the pressure between the outlet of the variable motor and the oil tank, which is used to simulate the pressure change in the pressure-resistant cavity. Through the present invention, the seawater pressure can be used for real simulation to drive operation equipment, and the control of seawater pressure, simulated load, pressure-resistant cavity pressure and variable motor speed can be realized, and the structure is simple and easy to manufacture.

Description

technical field [0001] The invention belongs to the field of marine ships, and more specifically relates to an experimental device for simulating seawater pressure energy operation equipment. Background technique [0002] Today, most countries that are close to the ocean are accelerating the pace of developing marine resources, and more and more deep-sea operation equipment has been successfully developed and put into use. In terms of power supply mode, deep-sea operation equipment is divided into two types: umbilical cord power supply and large-capacity battery power supply. One is the umbilical cord power supply method. Generally, the deep-sea operation equipment is powered by cables from the deployment ship on the water surface. This method can ensure operation. The equipment has sufficient power and is easy to control from the deployment ship, but the cost is high, the equipment is complicated, and the requirements for the deployment ship are high. At the same time, ther...

In terms of power supply mode, deep-sea operation equipment is divided into two types: umbilical cord power supply and large-capacity battery power supply. One is the umbilical cord power supply method. Generally, the deep-sea operation equipment is powered by cables from the deployment ship on the water surface. This method can ensure operation. The equipment has sufficient power and is easy to control from the deployment ship, but the cost is high, the equipment is complicated, and the requirements for the deployment ship are high. At the same time, there is also the problem of umbilical cable winding. Another way to use large-capacity batteries to power the operating equipment is to operate The equipment has its own battery pack, which frees itself from the shackles of cables and expands the range of activities. However, there are the following problems: First, the silver-zinc batteries commonly used in deep seas will precipitate some flammable gases, such as hydrogen, when the amount of gas evolution reaches a certain level. Explosion may occur when the battery pack is under water; the heat generated by the underwater lithium battery pack is very difficult to control, especially for high-power lithium batteries. Especially in the working environment of deep sea and high voltage, the resistance of the battery pack power supply to seawater leakage is very low. When the seawater seepage occurs in the battery pack, the consequences are more serious
