Future development of self-priming centrifugal pump

The strong self-priming pump is a water pump with a new structure. The negative pressure self-priming and self-priming water can reach a height of 8.5 meters and high pressure. It can work under a wide range of flow and head range. Jet self-priming device used by strong self-priming pump. The jet self-priming performance module is adopted, and various types of pumps are flexibly and flexibly configured. After start-up, the built-in control module works to quickly raise the low-level liquid to fill the pump cavity and deliver it.

Cavitation of self-priming pump

Features of strong self-priming pump:

1. When the strong self-priming pump is started, there is no need to backfill, no vacuum pump, and no bottom valve, the pump itself can automatically suck and suck liquid.

2. The self-priming height can reach 9m, which breaks through the limitation of the pump "allowable suction height".

3. The self-priming time is short, from 6.3m3 / h ~ 600 m3 / h, the self-priming time is only 6 ~ 50 seconds.

4. The suction device keeps the liquid level to the impeller always in a near vacuum state, which improves the efficiency of the pump.

Strong self-priming pump 5. During the operation of the pump, even if the phenomenon of "water loss" occurs, the air can be automatically pumped through the suction device to achieve the effect of self-recovery at any time.

Simple description of strong self-priming pump

1. The strong self-priming pump has a compact structure. This series of self-priming pumps have a horizontal structure. The pump is integrated, beautiful in appearance, and occupies less area. Compared with ordinary self-priming pumps, the floor space is reduced by 30%. If the IP54 outdoor motor is used, no pump room is required and it can be used outdoors.

2. The strong self-priming pump can be divided into three types: split type, direct connection type and easy-to-disassemble type. It is divided into two series of clean water type and sewage type according to the type. The characteristics of small, good self-priming performance, strong sewage capacity, energy saving, easy use and maintenance, are domestic * in the series of self-priming pumps. Various technical performance indicators are at home, reaching the level, and have a broad application market and development prospects.

Strong self-priming pump can meet the requirements of the process with suspended particles, corrosive liquid and slurry with a certain viscosity, is a single-stage single-suction cantilever centrifugal pump. Strong self-priming pump is a new product developed by technology. It is suitable for the transportation of liquids containing solid particles, oily sewage and various liquids that are not easy to produce foam. It can achieve "one-time drainage and self-priming for life". Depending on the transmission medium, stainless steel, reinforced polypropylene, carbon steel, cast iron, etc. can be used. Kinds of materials. Strong self-priming pumps are widely used in electronics, electric power, chemical industry, metallurgy, medicine, food, electroplating, environmental protection, fire protection, government, water purification, textile printing and dyeing, mining and beneficiation industries.

Cavitation of self-priming pump

The cavitation of the self-priming pump is caused by the vaporization of water. The so-called vaporization is the process of converting water from a liquid state to a vapor state. The vaporization of water has a certain relationship with temperature and pressure. Under a certain pressure, the water will begin to vaporize when the temperature rises to a certain value; if at a certain temperature, when the pressure decreases to a certain value, the water will also vaporize. This pressure is called the vaporization pressure of water at that temperature. If the pressure in a local area is equal to or lower than the vaporization pressure corresponding to the water temperature during the flow process, the water vaporizes there. After vaporization occurs, many small bubbles of steam and gas will form. When the bubble flows from the low-pressure area to the high-pressure area along with the water flow, the bubble bursts under the effect of high pressure, and the high-pressure water flows to the space occupied by these original bubbles at an extremely high speed, forming an impact force. The metal surface is fatigued due to water hammer pressure and is severely damaged. Therefore, we call the entire process of vapor bubble formation, development and rupture so that the material is destroyed, called cavitation.
