How to prevent water ring vacuum pump equipment detonating _

some users in the use of 2 bv will be confronted with exhaust blasting water ring vacuum pump. This phenomenon has a very bad effect to the operation of the equipment, and may even damage the equipment itself. When such problems, therefore, should be timely the related inspection, and take corresponding preventive measures, in order to prevent the problem from happening again. So, how to prevent water ring vacuum pump detonating equipment?

a, washing and buffer

add a wash before equipment and buffer tank can effectively eliminate the residual liquid suction, to have some cooling air mixture. But, in practice, often will appear the following two phenomena: first of all, when the amount of residual liquid in the tank, a small amount of liquid will be drawn into the pump body, and material at high temperature carbonization. Secondly, when large amounts of residual liquid, if not timely eduction, 2 bv water ring vacuum pump is likely to be inhaled liquid and produce washing pump, resulting in large equipment accident. Therefore, workers in the process of production need to have a strong sense of responsibility, and timely discharge of residual liquid, so as to avoid an accident.

prevent 2 bv water, waste gas control ring vacuum pumps noisily, strengthening waste gas control is a very important safety technical measures. The exhaust fumes from vacuum pump is mainly contains a lot of mixed gas of methanol vapor. According to the drunk tank and work habits of physical and chemical properties, in the buffer tank before, first installed a set or several sets of condensing unit ( About - usually use 10 ° C ice salt water) Condensate gas mixture; Second, in total exhaust system of 010, in 141455 also installed a condensing unit to condensing exhaust, to reduce exhaust gas of methanol vapor concentration detonating below the lower limit, and protect the environment. However, in the process of condensation, should be condensed water flow is controlled properly. If the traffic is too small, condensation effect may be very poor. If the traffic is too big, may be due to excessive condensation and pipeline, thus affecting the vacuum effect. Three, filters

in from 2 bv in the process of water ring vacuum water pump suction, a small amount of material and residual liquid is sucked into the pump valve plate, and adhere to some lubricating oil on the valve plate of the water pump. These materials at high temperature for a long time, carbide formation of carbon deposits. Under certain conditions, the mixture of combustible gas is easy to cause explosion, and through the eliminator trachea emissions, outward form a hiss.

in order to eliminate this kind of phenomenon, can be installed on the pump before the trachea filter equipment, to filter dust or residual liquid, and clean filter equipment on a regular basis to ensure good performance. At the same time, should be timely maintenance and clean the pump body. Practice has proved that the work should be performed every three months at a time.

4, trachea to prevent blocking or not smooth

trachea blocked or obstacles may lead to contain a mixture of methanol vapor gas generated in a timely manner. If the accumulated to a certain degree, may be strongly leak, result in detonating even noisily. Some of the reasons for this phenomenon. This could be due to a design flaw, the position of the trachea is relatively low. Water or oil product pipeline. Also may be due to some human factors or natural factors, The outlet valve, for instance) Caused by. Open or not fully open, the rain cover cover will collapse, causing the exhaust poorly. Therefore, in the design of vacuum pump, the design of the headquarters of the trachea and related accessories is also very important.

5, cooling

due to 2 bv water ring vacuum pump piston reciprocating motion continuously in the cylinder, so the temperature of pump body is too high, it provides material carbonization conditions, and cause an accident. In order to avoid this kind of circumstance, ask the operator to open the pump before you start the pump cooling system, and ensure that the system of entry and exit pipe unimpeded. Caused by not cooling water water pump body heat that the main reason of the accident is the operator of the sense of responsibility is weak, in violation of the operating rules and ignore it.

as a result, users in the use of 2 bv water ring vacuum pump before the relevant safety technical measures should be taken, can effectively avoid the detonating equipment. In addition, it is necessary to strengthen the safety of the operating personnel operating consciousness, for example, must be related to inspection before use, and always pay attention to the equipment in use process will appear problem, etc. To help guide the novice must choose professionals, on the one hand, prevent equipment damage, on the other hand to avoid novice due to improper operation and cause of the accident.
