Electric pump is to provide hydraulic fluid pressure of a hydraulic components, is a pump. Its function is to convert the mechanical energy of power machines (such as electric motors and internal combustion engines) into liquid pressure energy. The output flow can be adjusted according to the needs called variable pump, the flow can not be adjusted called quantitative pump. Hydraulic system commonly used pump gear pump, vane pump and plunger pump 3 kinds. Gear pump: smaller, simple structure, less stringent requirements on the cleanliness of oil, the cheaper prices; but the pump shaft by the unbalanced force, serious wear and tear, leakage larger. Vane pump: divided into double-acting vane pump and electric single-action electric pump hydraulic pump. This pump flow uniform, smooth operation, low noise, work pressure and volumetric efficiency than the gear pump, the structure is more complex than the gear pump. Piston pump: high volumetric efficiency, small leakage, can work under high pressure, mostly for high-power hydraulic system; but the structure is complex, high requirements of materials and processing precision, the price is expensive, the oil cleanliness requirements. Generally in the gear pump and vane pump can not meet the requirements of the plunger pump. There are some other forms of hydraulic pumps, such as screw pumps, but not as good as the above three kinds of universal. In the past, the products of our country all depend on imports, but with the increasing demand for such products in our country, our domestic products can also meet the production needs. We have a great advantage in terms of price, meanwhile, Performance, we also have the same advantage. So what are the advantages and disadvantages of electric hydraulic pump? Output flow can be adjusted according to the needs of the variable pump, called the quantitative pump can not be adjusted. Hydraulic system commonly used pump gear pump, vane pump and plunger pump 3 kinds. Through the analysis of the above three kinds of pumps, we can further understand that the advantages and disadvantages of the electro-hydraulic pump in different models and types may not be the same, but because of these differences, users can make the product purchase more Many options, such a variety of significance for the production. As many industries in our country increasingly demand such products, they are urgently needed to improve and innovate.
Mixing
and blending
operation is one of the most widely used unit operations
in chemical process. Mixer machine is broadly
used in pharmaceutical, food, health products, plastics, building materials,
light and pesticides industries.
Description
Theoretically we call the process of
putting any state of materials together as mixing. But traditionally we call
the humidification process of solid
materials as mixing and the blending process of solid, liquid or gaseous materials as stirring.
Application
Mixing
and blending
operation is one of the most widely used unit operations
in chemical process. Mixer machine is broadly
used in pharmaceutical, food, health products, plastics, building materials,
light and pesticides industries.
Principle
It
is required that all involved materials should be evenly distributed in the mixer machine. The mixing speed of all kinds of
materials depends on the proportion physical state and identity of the materials to
be mixed, the kinds of mixing machine being used and the duration of the mixing operation.
In
this mixer machine, solid particulars with
good mobility achieve their mixing by the rotation of the container itself. And
for those with poor mobility, it often requires mixing mechanics with
mechanical turning, pressing and rolling actions.
The
convective diffusion and eddy diffusion caused by mixing reduce the diffusion
distance and therefore shortens the time of molecule diffusion. If the
viscosity of the liquid to be mixed is high, it would take a long mixing time.
