Pump parts
A pump is a machine for conveying or pressurizing a fluid. It transfers the mechanical energy or other external energy of the prime mover to the liquid, so that the liquid energy increases. Pump parts chinaare mainly used to transport water, oil, acid and alkali liquid, emulsion, suspended emulsion and liquid metal and other liquids, also can transport liquid, gas mixture and liquid containing suspended solids.
From the performance range of the pump, the flow of the giant pump per hour can reach hundreds of thousands of cubic meters above, and the flow of the micro pump per hour is in the tens of milliliters below; The pressure of the pump can be up to 19.61Mpa(200kgf/cm2) from normal pressure. The temperature of the liquid to be transported can be as low as -200 ℃ or as high as 800 ℃. Pumps transport a wide range of liquid, such as water (clean water, sewage, etc.), oil, acid and alkali, suspension, and liquid metal.
Types of Valve Parts China
For liquids, environment types and operating systems are different, so there are a variety of valve types in China, each type can meet specific needs for different occasions. Some valves can be throttled, some valves are corrosion resistant and are specially designed for specific liquids, some valves are suitable for high pressure environments, and some can stop the flow of liquids. Buyers need to choose specific valves according to different needs and commercial uses, and each product has its own advantages and disadvantages.
It is important to understand these differences and how they affect the application or operation of the valve. The methods of controlling flow can be very different. Generally speaking, there are four: Move or rotate a disc, and slide a flat, cylindrical, or spherical surface, also can control the flow according moving a flexible material into the flow passage.controlling flow has a characteristic that makes it the best choice for a given application of function. ways to control flow through the valve.
Industries of Pump Parts
In agricultural production, pump is the main drainage and irrigation machinery. Pump parts in china are in great demand. Our country rural area original broad, every year rural area needs a large number of pumps, generally speaking, agricultural pumps accounted for more than half of the total output of the pump.
In the shipbuilding industry, there are generally more than 100 pumps used on each ocean liner, and the types are various.
Others such as urban water supply and drainage, steam locomotive water, lubrication and cooling machine tools, the textile industry in the transfer of bleaching and dye, pulp in the paper industry, as well as the food industry in the transfer of milk and sugar food, all need a large number of pumps.
Valve Parts
The device that controls the flow of water in the pipeline by changing the cross section of the pipeline is called valve. Valve partschinahas many kinds, such as bottom valve, gate valve, reverse valve and flap valve.
Valve Parts details
1）The bottom valve
Also calls as one-way valve, artificial water filling to prevent leakage and use, used to prevent leakage when filling water manually.
2）Gate valves
Installed on the outlet pipe, for closing valve (low pump) start, close valve stop, adjust the flow of accessories. Single valve should be selected according to the diameter of the water pipe, valve type, performance, specifications, working pressure and other correct choice.
3）Reverse valve
Installed on the water pipe, so as to prevent accidents when stop out of the water in the pool and outlet pipe back a one-way valve.
4) Flap valve
Installed in the outlet pipe outlet, in order to prevent the water in the pool to the outlet pipe backflow of a one-way valve, generally a complete set of water pump plant supply.
