Many customers often have some misunderstandings when purchasing and selecting laboratory vacuum pumps. Today we will discuss one of the common mistakes. Many customers often ask when purchasing a laboratory vacuum pump: Do you have a pump with a high power, I have to pump faster; if you have a pump with low power, our voice is smaller. In fact, the power is not directly related to the actual pumping effect. Pumps with low power do not necessarily mean that the noise will be small. So what is the connection between the power and some parameters? How do customers who need a fast pumping speed choose a pump that suits them? What parameters should customers pay attention to with low noise?
First of all, let's talk about the pumping speed of the laboratory vacuum pump. In fact, the most direct parameters that reflect the pumping effect of a pump in actual use are two items, namely vacuum degree and pumping speed. The degree of vacuum represents the maximum achievable pressure, and the pumping speed represents the length of time the pump is pumping. If the customer needs a pump that requires better suction, then a product with a higher vacuum and pumping speed should be purchased. Power only affects these two parameters indirectly. For example, the T242 laboratory vacuum oil pump can achieve a maximum vacuum of 0.05 torr, but the probability is only 250W. It can be said that the power consumption is less (power saving) and the vacuum is also very high, in addition to the general equipment, even It can be used together with equipments with high vacuum requirements, such as vacuum distillation and centrifugal concentration.
Secondly, the noise of the laboratory vacuum pump is actually related to the structural principle and detail design of the vacuum pump. A pump with a high power will have a relatively high level of noise, which is also a factor that indirectly affects noise. It is not an absolute cause. For example, the R410 laboratory vacuum pump has a vacuum of 0.097 MPa, but the noise is only 50 decibels. The customer does not feel particularly noisy when using it. This is because the design of the internal piston structure of the machine and the installation of the muffler components help the noise value. Reduced.
