Marine variable-frequency constant-pressure water supply system

Abstract

The invention belongs to water supply systems and discloses a marine variable-frequency constant-pressure water supply system which comprises a water supply device, a variable-frequency control cabinet module, a water storing barrel and a user terminal. A water inlet of the water supply device is connected with a water outlet of the water storage barrel through a water pipe while a water outlet of the same is sequentially provided with a pressure transmitter, a pressure controller and a first pressure meter along a water supply direction and connected with a water inlet of the user terminal, and the pressure transmitter and the pressure controller are in signal connection with the variable-frequency control cabinet module which is electrically connected with the water supply device. The marine variable-frequency constant-pressure water supply system has the advantages of accuracy in pressure adjustment, constant pressure, low noise, high efficiency and high reliability and is of important significance in water supply of ship equipment.

Description

technical field [0001] The invention belongs to a water supply system, in particular to a marine frequency conversion constant pressure water supply system. Background technique [0002] The pressure water tank is a kind of water supply equipment commonly used in ships. It supplies water to various water places by maintaining a certain pressure in the pressure water tank. The pressure water tank is equipped with high and low pressure controllers, which can automatically turn on and off the water pump. The pressure in the cabinet is kept within a certain pressure range. In actual use, the pressure water tank has the following three major disadvantages: 1. Due to the increase of the user's water demand, the cylinder of the pressure water tank is generally large in volume and heavy in weight. The contradiction is particularly prominent; 2. The general water supply pump has a large current and high energy consumption at the moment of starting. Frequent starting of the water p...

Problems solved by technology

In actual use, the pressure water tank has the following three major disadvantages: 1. Due to the increase of the user's water demand, the cylinder of the pressure water tank is generally large in volume and heavy in weight. The contradiction is particularly prominent; 2. Generally, the instantaneous current of the water supply pump is large and the energy consumption is high

Frequent starting of the water pump will cause great damage to the motor and poor reliability; 3. The water supply pressure of the pressure water tank is within a certain range, the pressure fluctuates greatly, and the constant pressure cannot be maintained during the water use period, which cannot meet the needs of special water use places.

[0003] The existing technology has been used for many years without any technical improvement. Many users of pressure water tanks have put forward the demand for improvement. Therefore, it is necessary to study and find out the solution to the problem, and make corresponding improvements to meet the needs of users.
