Treatment of water leakage of water ring vacuum pump

Treatment of water leakage of water ring vacuum pump

Although the operation of water ring vacuum pump itself is not complicated, it can't help but sometimes the pump will be damaged due to improper use, which will cause some problems, such as water leakage of the equipment. I believe that many friends have met it, which will directly affect the production efficiency of the equipment, so what are the causes? What should be done? Let's take a look:

1. Water leakage caused by cracks in pump housing

If the shell cracks and leaks water, you can wipe the cracks clean, and then use adhesive to mend. In case of emergency, cement and egg white can be mixed to form a paste and applied to the crack, which can be used after several minutes of solidification.

2. Water leakage of water ring vacuum pump in operation

If the equipment under operation is found to be leaking water, do not stop it immediately, but keep it at a lower stable speed, and then add water to the cooling system and drain water (Note: when the water filler cap is opened again, a cover should be placed above it, in order to prevent scalding by the water vapor). Make the engine cool down, drive slowly, drive to the nearby concealed place and then drain Except.

3. Water leakage due to shell rupture

In case of water leakage due to breaking of equipment shell or damage of pump internal parts, relevant parts can be replaced according to the actual situation to eliminate the fault.

Through the description of water leakage of the above-mentioned water ring vacuum pump, we can take appropriate measures to solve the problem, so as to avoid affecting the operation of the equipment to a greater extent. In addition, in case of emergency, if the water leakage is not very serious, we can lay a piece of abrasive cloth on the glass plate or flat plate, and then grind the sealing plane flat, or we can also turn the bakelite water seal over and use it again Solve problems in time.

How to make vacuum pump absorb water automatically?

Automatic water absorption, first of all, there must be suction, that is, power to help the water absorption tool realize this process. For the vacuum pump, you can also use the following methods to achieve this process.

1. When the vacuum pump stores water, it can be placed nearby, and the bottom of the barrel is slightly higher than the water outlet of the pump; or when the water outlet pool is built on the side close to the pump room, the bottom of the pool is slightly lowered to form a water storage pool. Connect the barrel (or pool) and the water filling hole of the pump body with a water pipe. Before shutdown, use the water from the water outlet pipe to fill the bucket for standby. When the next start-up, the bucket can flow and fill water automatically. This method is easy to use.

2. The muffler of the small engine is unloaded by the method of engine exhaust, vacuum and water filling, and a special exhaust water diversion device is installed. The exhaust gas discharged during the operation of the engine is used to extract the air, so that the vacuum pump can produce a certain degree of vacuum. During operation, start the engine first, then press down the handle of the exhaust water diversion device, close the exhaust gas outlet, and exhaust the exhaust gas from the engine through the exhaust gas jet nozzle. Due to the high speed and low pressure of the exhaust gas jet, the exhaust gas will be sucked out.

3. A cylindrical water tank is installed in front of the vacuum pump by the water tank diversion method in front of the pump. The top of the tank is a hemispherical protrusion. A section of suction pipe is installed in the middle of the tank. The pipe orifice is lower than the height of the cylinder body. The lower outlet of the tank body is connected with the suction pipe of the vacuum pump. Before the water tank is used for the first time, fill the water tank with water from the water filling port, and then close the water filling port.

How to change the speed of vacuum pump

Now the vacuum pump factory will introduce the method of changing the speed of vacuum pump, hoping to help you.

1. Change the frequency of power supply, i.e. use frequency converter. The advantage of frequency converter is that it can provide a closed-loop control for vacuum pump, but it is easy to cause torque loss under large load.

2. Change the transmission ratio of the gearbox. It is a very economical way to change the transmission ratio of the gearbox of the vacuum pump, but it can only provide a single uncontrollable speed. Vacuum pump has different design, they have their own characteristics and advantages and disadvantages. For a long time, the use cost of vacuum pump is an important factor that affects people's choice of vacuum pump. After research and development, it has great advantages in stability and maintenance cost in the future.

Wide application of vacuum unit

Wide application of vacuum unit

When the vacuum unit is used, it can be used to pump not only the general gas, but also the gas containing moisture, organic solvent or a small amount of dust. Compared with the general mechanical vacuum pump, it is not afraid of oil pollution, water gas and dust. Compared with the general water ring vacuum pump, it has the characteristics of high vacuum degree and high pumping speed under high vacuum degree.

Vacuum unit is widely used in chemical, electronic, mechanical, pharmaceutical, food sublimation drying, high altitude simulation test and other vacuum systems. Because the 2BV series water ring pump with high efficiency and energy saving is used as the front stage pump, jzj2b series vacuum unit has the advantages of high efficiency, compact structure, no leakage (2BV pump is designed as mechanical seal, different from the packing seal of 2SK Series), corrosion resistance (2BV uses aluminum bronze impeller), and high protection level compared with jzj2s series.

When the working fluid in the front pump of the vacuum unit is changed to oil, the limiting vacuum degree of the roots vacuum unit can be effectively improved (see the parameter table). The roots oil ring unit is a closed-circuit circulating system, which can reduce pollution and save water. Roots oil ring vacuum unit is widely used in vacuum impregnation, vacuum drying, vacuum degassing and other processes.

The working liquid of the pre-stage pump can also be organic solvent (methanol, ethanol, xylene, aniline, acetone and other organic solvents with low viscosity can be used) or other liquids. The pre-stage pump can be used as a closed-circuit circulation system, which greatly reduces the environmental pollution and greatly improves the recovery of organic solvent. The limiting vacuum is determined by the saturated vapor pressure of the working fluid.

Water ring pump is more advantageous than other vacuum pumps in vacuum unit, because it can pump out a large number of condensable steam, especially when the ability of removing condensable steam is not enough, or the solvent used can make the pump oil deteriorate and affect the performance, or the vacuum system does not allow oil pollution. In the selection of vacuum units, it is generally required that the limiting vacuum degree of the vacuum units should be half to more than one order of magnitude higher than the working vacuum degree in order to meet the use requirements, that is, the working pressure should be ≥ the limiting pressure × (5-10).

Working pressure of vacuum pump

In the process of using the vacuum pump, its working strength should meet the requirements of the limit vacuum and working pressure of the vacuum equipment. For example, vacuum coating requires a vacuum degree of 1 × 10-5mmhg, and the vacuum degree of the selected vacuum pump shall be at least 5 × 10-6mmhg. Generally, the vacuum degree of the pump is half to one order of magnitude higher than that of the vacuum equipment.

The correct choice of the working point of the vacuum pump, each pump has a certain range of working pressure, such as: diffusion pump is 10-3 ~ 10-7mmhg, in such a wide range of pressure, the pumping speed of the pump changes with the pressure, the stable working pressure range is 5 × 10-4 ~ 5 × 10-6mmhg. Therefore, the working point of the pump should be selected within this range, and it cannot be allowed to work for a long time under 10-8mmhg.

Under its working pressure, the vacuum pump should be able to discharge all the gas produced in the process of vacuum equipment. Combine the vacuum pump correctly. Because of the selective pumping of vacuum pump, sometimes selecting one pump can not meet the pumping requirements. Several pumps need to be combined to supplement each other to meet the pumping requirements. For example, the titanium sublimation pump has a very high pumping speed for hydrogen, but it can't pump helium, while the three pole sputtering ion pump (or the two pole asymmetrical cathode sputtering ion pump) has a certain pumping speed for argon, and the combination of the two will make the vacuum device get a better vacuum degree. In addition, some vacuum pumps can't work under atmospheric pressure and need pre vacuum; some vacuum pumps need pre stage pumps because the outlet pressure is lower than atmospheric pressure, so they need to be combined for use.

Requirements of vacuum equipment for oil pollution. If the equipment is strictly oil-free, various oil pumps should be selected, such as: water ring pump, molecular sieve adsorption pump, sputtering ion pump, low temperature pump, etc. If the requirements are not strict, oil pump can be selected, and some anti oil pollution measures, such as cold trap, baffle, oil trap, etc., can also meet the requirements of clean vacuum.
