Water ring vacuum pump is a new generation product developed by our company. It has the characteristics of strong corrosion resistance, high limit vacuum degree and large exhaust capacity. So why does the vacuum drop in summer when the water ring vacuum pump is used? 1. Under working conditions in summer, water ring vacuum pump adopts circulating water to cool working water. High temperature of circulating water will lead to the decrease of suction capacity and efficiency of water ring vacuum pump. Through analysis, the working water of the water ring vacuum pump is cooled by the refrigerated water of the central air conditioner of the power plant 2. Other conditions being unchanged, the lower the working water temperature, the smaller the influence on the vacuum of the water ring vacuum pump, while the higher the working water temperature, the greater the influence on the vacuum 3. For the double back-pressure condenser, due to the low pressure of the condenser corre

Vacuum pump maintenance manufacturers talk about the vacuum pump to reduce friction method text: today, vacuum pump maintenance manufacturers here to introduce the vacuum pump to reduce friction method. The vacuum pump can remove the dry gas in the sealed container of the constant temperature and humidity test chamber. But it is not suitable for removing gases that contain too much oxygen, are corrosive to metals, react chemically with pumped oil, or contain particulate dust. Vacuum pump is one of the most basic vacuum acquisition equipment in vacuum technology. Vacuum pump for small and medium-sized pump. Rotary vane pump has a single stage and two stages. The so-called two-stage, is in the structure of two single-stage pump series. Generally made of two - stage, in order to obtain a higher vacuum degree. The vacuum pump body is equipped with an appropriate amount of water as the working fluid. When the impeller rotates clockwise as shown in the figure, the water is t

Screw vacuum pump in use, sometimes there will be insufficient compression, hangzhou xinanjiang industrial pump to solve the problem of insufficient compression of screw vacuum pump: 1, in the screw vacuum pump, the auxiliary exhaust valve is a special structure, the general use of rubber ball valve, its role is to solve the screw vacuum pump in the process of running the phenomenon of over compression and insufficient compression. The two phenomena can cause excessive power consumption, because there is no direct water ring vacuum pump exhaust valve, and exhaust pressure is always fixed, water ring vacuum pump compression ratio't decided to port of termination of the starting position of the location and vent, the two position fixed, so don't meet the needs of the suction pressure changes 2, in order to solve the problem of screw vacuum pump, generally set rubber ball valve at the bottom of the exhaust port, so that when the screw vacuum pump pump chamber reac

Water ring vacuum pump is generally most of the industry applied to the vacuum pump, recently some customers said the circulating water vacuum pump pressure on the problem, small make up five points, look at the vacuum pump vacuum degree on the problem is where, together to solve. 1. The water temperature is too high ~ the normal circulating working water temperature is about 40 ° c. At this temperature, the efficiency of vacuum pump will not fall too low. 2. Leak. Open the lid and check whether the connecting pipe is broken and leaking, which causes the pressure to go up. If it is, the tube should be replaced, which is generally a 6-port latex tube. 3. Insufficient water intake. First of all, we should touch whether the pump shell is hot or not to see whether there is water flowing out of the water outlet. If the pump shell is hot and there is no water flowing out of the water outlet, we just need to increase the amount of water flowing into the water inlet to make t
