I think many friends are very interested in the excitation control of water ring vacuum pump, this is really a key and difficult work, next I will introduce some relevant content, you can read it carefully. 1. Open-loop simulation test for…
1, water ring vacuum pump is a crude vacuum pump, by the pump body, impeller, suction and exhaust disc, water in the pump body wall water ring, exhaust port, suction port, auxiliary exhaust valve, etc. About the two-stage pump is 0.133 ~ 0…
In this paper, a new kind of water-based film adhesive, applied in the vacuum aluminum plating pet composite glass paper production process, the printing plant shows that the adhesive has a fast drying speed, extrusion compound process is …
As anyone who knows about the central vacuum pump will know, the reason why the rotary vane vacuum pump has a high vacuum degree is that the clearance between the rotary vane and the rotor is very accurate. If the rotary vane is worn, it w…
As can be seen from the formula S=Q/P1 of the vacuum pump pumping rate, when the vacuum system leakage rate Q is constant, the effective pumping rate S of the mechanical pump is inversely proportional to the vacuum degree P1 of the pre-wat…
Rotary vane vacuum pump is a device that can generate, maintain and improve vacuum in a certain space through various ways. It is mainly used in chemical, food, electronic and other industries and plays a crucial role in promoting the prog…
Notes: 1. The water ring vacuum pump outlet is generally not connected with the valve. If there is, it must be fully opened before starting 2, without water can not start operation, but the amount of water can not be too much. Water ring v…
EVP vacuum pump manufacturers to introduce a water ring vacuum pump working principle is what? Water ring vacuum pump (referred to as water ring pump) is a crude vacuum pump, which can obtain the limit vacuum of 2000~4000Pa, series atmosph…
A, the nozzle The nozzle is an important part that affects the performance of the vacuum pump. There are some problems: the nozzle is installed wrongly, installed crooked, blocked, damaged, corroded and leaked. On the one hand, when instal…
Single-stage rotary vane vacuum pump is also called XD rotary vane vacuum pump. Today xiaobian will give you a detailed introduction to the use and maintenance of single-stage rotary vane vacuum pump, small partners can remember it! XD rot…
How to reduce the vacuum pump energy consumption? When we choose a vacuum pump, we should not only consider its quality and efficiency, but also consider whether the energy consumption is high or not. Generally, we will choose the one that…
