Description

Technical part

The utility model relates to an operating system of the desalination pump.

State of the art

At present, the desalination pump system is designed for two large desalination pumps with a rated capacity of 300 m3/h each, operating at frequency I, and one small desalination pump.

When the plant starts high water replenishment, the large desalination pumps work at frequency I and are unable to regulate the desalination water outlet pressure, which directly reaches the rated pressure, resulting in the desalination water pressure in the bus varying between 0, 35 and 0.65 MPa varies. When the pressure in the brine mother line is high, the small desalination pump will hold the pressure for a long time, which will cause the small desalination pump to leak and damage the discharge valve, check valve and liner of the pipe.

Content of the utility model

The purpose of the utility model is to remedy the deficiencies of the prior art by providing an operating system for the desalination pump.

• Ein Betriebssystem der Entsalzungspumpe mit einem Niederdruckkreislauf und zwei Hochdruckkreisläufen, wobei der eine Niederdruckkreislauf und die beiden Hochdruckkreisläufe parallel geschaltet sind, wobei die Einlassseite mit dem Einlass-Endmischer und die Auslassseite mit dem Auslass- Endmischer verbunden ist;
• wobei der Einlass-Endmischer mit der Einlass-Hauptleitung verbunden ist und der Auslass-Endmischer mit der Auslass-Hauptleitung verbunden ist;
• Die Einlass-Hauptleitung ist mit der Auslass-Hauptleitung durch eine Bypass-Leitung verbunden.

The aforementioned purpose is achieved by the following technical solution:

• An operating system of the desalination pump with a low-pressure circuit and two high-pressure circuits, the one low-pressure circuit and the two high-pressure circuits being connected in parallel, the inlet side being connected to the inlet-end mixer and the outlet side being connected to the outlet-end mixer;
• wherein the inlet end mixer is connected to the inlet header and the outlet end mixer is connected to the outlet header;
• The inlet main line is connected to the outlet main line by a bypass line.

The operating system of the desalination pump, the low-current circuit includes a small desalination pump and two manual control valves, with two of the manual control valves installed in the small desalination pump. Small desalination pump are installed on the inlet and outlet side.

The operating system of the desalination pump, the high-flow circuit includes a large desalination pump and two manual control valves, with two manual control valves installed on the inlet and outlet sides of the large desalination pump, respectively.

Said operating system of the desalination pump, said bypass line is equipped with an electric control valve.

1. 1. Das Gebrauchsmuster ist mit einem Manuellen Regelventil am Ausgang der großen Entsalzungspumpe des High-Flow-Kreislaufs ausgestattet, das den Der Ausgangsdruck und die Durchflussmenge der großen Absalzpumpe können reguliert werden, während der große Kreislauf und der kleine Kreislauf zum Mischen gemeinsam an den Wassermischer angeschlossen sind, so dass ein Teil des Drucks zum Mischen entnommen werden kann und ein zu hoher Ausgangsdruck verhindert wird.
2. 2. Das Gebrauchsmuster ist mit einer Bypass-Leitung ausgestattet, und das elektrische Regelventil an der Bypass-Leitung, zusammen mit dem großen Absalzpumpenausgang Manuelles Regelventil auf der Bypass-Leitung dient dazu, die Öffnung der elektrischen Regelklappe des Bypasses einzustellen, um einen stabilen Druck des entsalzten Wassers zu erreichen und den Druck des entsalzten Wassers zu kontrollieren.

Useful Effects:

1. 1. The utility model is equipped with a manual control valve at the outlet of the large desalination pump of the high-flow circuit, which allows the output pressure and flow rate of the large desalination pump to be regulated, while the large circuit and small circuit together to the water mixer for mixing are connected so that part of the pressure can be removed for mixing and an excessive outlet pressure is avoided.
2. 2. The utility model is equipped with a bypass line, and the electric control valve on the bypass line, together with the large bleed pump outlet Manual control valve on the bypass line is used to adjust the opening of the bypass electric control valve to achieve stable pressure of the desalinated water and to control the pressure of the desalinated water.
