From the pump performance range, giant pump flow up to hundreds of thousands of cubic meters per hour or more, while the micro-pump flow rate is less than dozens of milliliters per hour; pump pressure from the normal pressure up to 19.61Mpa (200kgf / cm2) above; the temperature of the liquid being transported as low as -200 degrees Celsius, the highest up to 800 degrees Celsius. Pumps deliver a wide variety of fluids, such as delivering water (clean water, sewage, etc.), fluids, acids and alkalis, suspensions, and liquid metals.
In the production of the chemical and oil sectors, raw materials, semi-finished products and finished products are mostly liquids, whereas the conversion of raw materials into semi-finished and finished products requires complicated processes that pump to deliver liquids and provide chemical reactions with pressure flow In addition, in many devices also use the pump to adjust the temperature.
In agricultural production, pumps are the main irrigation and drainage machinery. A vast rural areas in our country, every year in rural areas require a large number of pumps, agricultural pumps in general account for more than half of total pump output.
Pumps are also the most widely used equipment in the mining and metallurgical industries. The mine needs to be drained by a pump. In the process of beneficiation, smelting and rolling, the pump is required to supply water first and so on.
In the power sector, the nuclear power station needs a nuclear main pump, a secondary pump, a tertiary pump, and a thermal power plant which require a large number of boiler feed pumps, condensate pumps, circulating pumps and ash pumps.
In the national defense building, the regulation of aircraft flaps, tail rudders and landing gear, the rotation of warships and tank turrets, the ups and downs of submarines, etc. require the use of pumps. High pressure and radioactive liquid, some also require the pump without any leakage.
In the shipbuilding industry, the number of pumps used on each ocean going wheel is generally more than 100 and its type is also varied. Others, such as urban water supply and drainage, steam locomotive water, lubrication and cooling in machine tools, transporting drifts and dyes in the textile industry, transporting pulp in the paper industry, and transporting milk and sugar foods in the food industry, require large quantities Pump.
In any case, pumps, pumps, running pumps, tanks, submarines, or drilling, mining, trains, ships, or everyday life are needed everywhere. This is the case, so the pump as a general machinery, it is a kind of mechanical industry in the product.

PVC Edge Banding For Office

The main function of the edge banding is to seal the cross-section of the board, so as to avoid the damage of the board and the adverse factors (mainly moisture) in the process of use and prevent the formaldehyde inside the board from volatilizing, and at the same time achieve the effect of beautiful decoration.

The product has the following main features: smooth surface, no blistering, no ribbing, moderate gloss, smooth surface and back surface, uniform thickness, uniform width, reasonable hardness, high elasticity, good quality, strong wear resistance, trimmed and sealed The color of the side and the side is close to the surface color, not whitish, good gloss, and the overall color of the finished furniture is coordinated.

The role of edge banding:
First, the edge banding has the function of blocking harmful gases such as formaldehyde
Good edge banding or multi-sided edge banding can reduce the amount of formaldehyde emission per unit time (ie, slow down the emission rate). It is worth noting that edge banding will not reduce the formaldehyde content of the board, but this has the advantage of edge banding. It can reduce the formaldehyde emission per unit time of unenvironmentally-friendly sheets to a level that is acceptable to humans and does not affect health.
Second, the role of beautifying furniture
Good edge banding has the effect of beautifying office furniture, but if it is to be beautiful, the requirements for edge banding will be higher. Not only must the edge banding and the end surface of the board be firmly and smoothly combined, but also that the edge banding must be combined with other The joints of the surfaces should not have defects such as bottoming, chipping, and large gaps, and the transition should be natural, smooth and smooth.
Third, extend the service life of office furniture
The precise edge sealing design of the board can prevent water or other liquids from entering the board, avoiding the expansion, deformation and breeding of bacteria on the desktop, thereby prolonging the service life of the office furniture, and the office furniture after the edge sealing treatment is also more expensive in terms of cleaning easy.
Fourth, avoid sharp edges and corners from hurting people's bodies
The general edge banding will use the dull edge banding design to smooth the corners of the table, thereby reducing the damage to the body by the sharp corners
