Some knowledge points of foam pump


According to its unique overall design, the foam pump can be effectively integrated into the foam in the flotation and other mineral processing fields, so it is called a foam pump, which is actually a centrifugal slurry pump.

Due to the whole process of industrial production, some floating foams may be formed in the whole process of pulp transportation, such as flotation in beneficiation. Foamed plastic will appear in the pulp in the flotation field, so the general submerged slurry pump is not suitable for conveying this kind of foamed plastic pulp in the beneficiation.

The water pump impeller of the foam pump is a double-shell structure, and part of the overcurrent is made of hard nickel, high chromium or plastic materials, and the transmission system is the same as the EVM submerged slurry pump. The feeding box of the silo is constructed of thick steel plate, which can cover the lining according to the different materials to be conveyed, and the inlet and outlet of the pump can be replaced every 45 degrees. When the pump is working, the foam in the slurry can be removed reasonably, and it can still work normally when the feeding is not enough, without all the water pump seal and shaft seal.

The foam pump is suitable for various flotation processing processes, and is an ideal pump for conveying foamed plastic slurry. The delivery volume far exceeds other types of goods. Foam pumps are also suitable for metallurgical industry, mining, coal, chemical plants and other fields to transport strong corrosion and corrosion-resistant slurries containing foam.

To apply the foam pump note:

1. Pay attention to the adjustment of the centrifugal impeller. To ensure the efficient operation of the pump, the clearance between the centrifugal impeller and the flasher must be adjusted immediately.

2. In actual operation, add an appropriate amount of vegetable oil.

3. If the foam pump is not used for a long time, the rolling bearing should be rotated 1/4 turn every week so that the bearing can bear the static load and external vibration evenly.

4. Before stopping the pump, let the pump be cleaned for a period of time as much as possible to clean the slurry passing through the pump, and then turn off the inlet gate valve and the inlet and outlet valves successively.

Before the invention of the foam pump, foamed plastics were usually sprayed out by commercial sprays, that is, foamed plastics were produced by inflating with liquefied petroleum gas, or foamed plastics were produced by using a polyurethane foaming agent. The characteristic of the working pressure foam pump is that the pump casing consists of an air pump and a gas filter. The liquid is completely mixed with the gas in the pump body, the ejection volume is stable, the use is convenient, and it will not be harmed by the customer's operation method, and the foam plastic is of good quality.

Compared with foam plastic spray products, foot massage foam pump has many significant advantages: First, it does not need to add rocket fuel, it is not easy to pollute the environment, it is not easy to inflammable and explosive materials, it does not need stainless steel containers and airtight inflatable equipment, low cost, It can be reused many times; secondly, the liquid secret recipe of foot massage foam pump is mostly oil-based, which is essentially non-volatile organic compounds (VOCs), which is very worthy of marketing and promotion. Third, utensils of various shapes can be applied, including square, triangular, oval, etc. In addition, there is no pressure on the utensils before application, and the selection area of ​​utensil raw materials is relatively wide.
