How to repair the big cover and the small cover in the double-acting vacuum pump? In the double-acting vacuum pump, the cooperation between the small cover and the blade is that the cone coordinates with each other and has relative motion. In the working process, the pump is most vulnerable to chlorine and sulfuric acid erosion, but also vulnerable to unclean gas, liquid solid glumes or impurities wear. After such wear and tear on the conical surface, uneven convex and concave defects will occur, which can be repaired by the following methods: If the cover is not seriously damaged, the rust on the surface can be wiped off with No. 3 abrasive cloth, then coated with a thin layer of red red, the impeller is matched with it, and the impeller is rotated several times by hand, then the conical surface can be observed. The polished part of the small cover shows that it is a higher part and can be filed flat with a file. The red-red mark on the conical surface of impeller is al

Summary: If the rotary vane vacuum pump is not properly operated, it will often fail. For example, the vacuum degree of the rotary vane vacuum pump decreases, oil injection, smoke, oil leakage at the oil seal, noise and so on, and the phenomenon of oil emulsification of the vacuum pump in the pump. In case of such a situation, first of all, do not panic, and after the shutdown, according to the fault one by one elimination. Here are some troubleshooting methods. Smoke and fuel injection of rotary vane vacuum pump: Smoke or fuel injection from exhaust port of rotary vane vacuum pump in operation. 1. Smoking, if the pump has just started to operate smoking phenomenon, belongs to normal, if smoking for a long time is abnormal. Solution: Smoke shows that the pump intake, including pipelines, valves, containers are repaired. After leak detection, the smoking will end. Vortex Flowmeter 2. Fuel injection indicates that there are a lot of leaks outside the intake, even the i

On the basis of increasing the level of product manufacturing, the workshop of water ring vacuum pump also strengthens the management of workshop environmental hygiene. Because of the large number of orders and the complexity of products, the management of workshop environment has not been strengthened in the short-term production process, which makes the whole clean workshop deviate from the quality management mode. With the emergence of this problem, workshop leaders also made timely adjustments to speed up the arrangement and management of workshop operators, and to strengthen the thorough cleaning of all dead corners. After a week of intensive work, all aspects of the water ring vacuum pump workshop fully reflect the high-quality image of the workshop, from the use and management of equipment to the ground cleanliness, highlighting the importance of the work, but also to provide users with a more solid sense of trust, only the environment has been improved, product q

If you want to use this product better, you must have a comprehensive understanding of it. Water ring vacuum pumps are the same. Now let's understand the whole process of natural ventilation of sewage ring vacuum pumps. Water ring vacuum pump discharges gas outward, which reduces the standard air pressure in the room and makes the indoor air quality thinner. It generates an air pressure zone. The gas is compensated for the standard air pressure difference and injected into the room. In the practical application of the workshop, it is centralized installed on one side of the industrial workshop, and the air inlet is located on the other side of the industrial workshop. During the whole process, the aluminium alloy doors and windows close to the water ring vacuum pump are closed, forcing the gas to be compensated by the aluminium alloy doors and windows on the side of the air intake into the production workshop, and the gas is queued up and disciplined and injected int

High frequency discharge is the form of discharge caused by the presence of high frequency alternating electric field between two electrodes. When the alternating voltage is applied at both ends of the discharge tube, the electrons and positive ions in the gas will produce additional resonance under the action of alternating electric field. Because the mass of positive ions is much larger than that of electrons, the resonance amplitude is very small. When the frequency is low and the amplitude of the resonance is much larger than the distance between the two poles, the electrons go through the whole process of collapse, discharge and extinction in each half cycle. At this time, the discharge situation is the same as that of DC. When the frequency is high and the amplitude of the resonance is far less than the distance between the two poles, the ionization ability of the electrons will be greatly enhanced due to the continuous back and forth motion of the electrons.

Screw vacuum pump is widely used in life for its advantages of wide pumping speed range, simple and compact structure, no friction of the components of the pump chamber, long life, low energy consumption and no oil pollution. Moreover, electricity is the power source of the screw vacuum pump, and the way of obtaining electricity can also be different. The influence of different power supply modes on the equipment is different. It's also different. 1. Screw vacuum pump because the extraction medium is "water or liquid", is characterized by a larger proportion, and micro vacuum pump, micro air pump and other working medium is "gas", a lighter proportion. Therefore, the working current of screw vacuum pump is generally larger than that of the latter, about 1 to 10 amperes, while the latter's working current is generally not large, ranging from several hundred milliamperes to several amperes. 2. Batteries. Battery is the general term of battery. B

Oil-free dry mechanical vacuum pumps (hereinafter referred to as dry mechanical pumps) refer to mechanical vacuum pumps that can start pumping from atmospheric pressure and directly discharge the pumped gas into the atmosphere. There is no oil or other working medium in the pump chamber, and the limit pressure of the pump is the same or close to that of oil-sealed mechanical vacuum pumps. At present, most mechanical vacuum pumps used in vacuum industry use oil, water or other polymers as working media of pumps, which play many roles such as cooling, sealing, lubrication and so on. With the development of science and technology and the expansion of vacuum application field, an overview of the original mechanical vacuum pump and its composition of oil-free dry mechanical vacuum pump There are two urgent problems to be solved in the gas system. One is that the working medium of the pump pollutes the pumped container, which in many cases affects the quality and quantity of t

Cavitation often occurs in the use of screw vacuum pump, which is a high noise and destructive phenomenon often occurring in hydraulic machinery. The occurrence of this phenomenon will not only break the vacuum pump, but also cause impeller perforation to cause serious damage to the equipment. The mechanism of cavitation is due to the action of liquid dynamics. When the local pressure of moving liquid drops to the vaporization pressure at this temperature, the liquid begins to vaporize and forms bubbles. The bubbles are filled with liquid vapor and a small amount of gas dissolved in the liquid. When the bubbles reach the region where the static pressure exceeds the critical pressure along with the moving liquid, the steam in the bubbles suddenly condenses and the bubbles burst. Because the pressure in the bubbles is always below or near the critical value, and the pressure of the outside liquid is relatively large, when the bubbles burst, the surrounding liquid rushes to

Corrosion-resistant vacuum pump is composed of pump as the main pump and rotary vane pump as the front pump in series. In order to make better use of it, we should understand its water filling method. The following edition will give you a detailed introduction: 1. Artificial filling method: For small pumping stations whose diameter of intake pipe is less than 300 mm, there is usually a bottom valve at the inlet of intake pipe. Generally, artificial filling method is adopted, that is, the water is filled by a filling funnel (or an inverted ordinary bottle without the bottom of the bottle) from the special filling vent on the upper part of the corrosion-resistant vacuum pump shell. For small pumping stations with inlet pipe diameter less than 300 mm, a bottom valve is usually installed at the inlet of the inlet pipe, and water can also be filled into the pump from the outlet of the corrosion-resistant vacuum pump (the pumping station with shorter outlet pipe). Because ther

With the whole level of dry vacuum pump, we should accelerate the ability of product production, enhance the performance of its strength in all aspects, increase investment in product development, actively learn advanced skills in all aspects, enhance the ability of self-development, and then show the function of dry pump. Dry vacuum pump is the trend of future career development. Although it is not used much now, besides the high price, there are also users who do not know the dry vacuum pump well and can not see the future economic benefits brought to enterprises. Here, how to optimize the selection of dry vacuum pump is emphasized. For these different types of dry vacuum pumps, we all hope to reduce their physical scale. But this is opposite to the pumping rate of the vacuum pump, because the pumping rate of the vacuum pump is proportional to the volume of the vacuum pump, small physical scale means small volume. Of course, there is also an important factor affecting

Everyone knows that stainless steel vacuum pump is a kind of equipment which obtains vacuum by mechanical, physical, chemical or physical chemical methods. It is used for vacuum extraction at the start of the unit. Normally, it is used to extract the unconsolidated gas in the condenser. Every summer, the temperature of the motor will exceed the limit, while the motor will be high for a long time. Temperature operation will cause insulation aging and shorten its service life. The reason why the temperature of stainless steel vacuum pump motor is too high is introduced below. 1. Stainless steel vacuum pump fan speed is low, wind pressure, air volume is small. 2. The number of fan blades is small and the amount of air generated is small. 3. Stainless steel vacuum pump motor has high power, high working current and high calorific value. Fourth, the motor has dust and oil pollution, which reduces the heat dissipation capacity. Fifth, the bus voltage of the stainless steel vac
