Liquid ring vacuum pump manufacturer

In addition to the original B-A ultra-high vacuum gauge, the full-pressure side of the ultra-high vacuum system has developed many extremely high vacuum gauges, such as cold cathode magnetic control gauges, suppression gauges and bend gauges. But for many research work, it is not enough to rely solely on full pressure data.

For example, adsorption, condensation, desorption processes, etc. in vacuum systems involve the interaction of the surface of the vessel with the material inside the system and residual gas molecules. At this point, obtaining data on the gas composition and partial pressure in the system is more telling than the full pressure data. Gas analysis and partial pressure measurement under vacuum conditions are usually performed by a dynamic mass spectrometer. If the solid medium is contained in the medium to be transported, a filter should be added to the pump inlet: if it contains ferromagnetic particles, a magnetic filter is required. The ambient temperature of the water ring vacuum pump should be less than 40 °C during use, and the motor temperature rise should not exceed 75 °C. After 1000 hours of normal operation of the magnetic pump, the wear of the bearing and the end moving ring should be dismantled, and the wearing parts that are not suitable for reuse should be replaced. The conveying liquid is a medium that is easy to precipitate and crystallize. After use, it should be cleaned in time. liquid.water-ring-vacuum-pump-and-compressor-for-vacuum-packing

The vacuum pump must be kept clean at all times. No other objects should be placed on the vacuum pump. Do not block the passage around the vacuum pump for maintenance and operation. Always pay attention to the tightness of the V-belt and adjust it. Always pay attention to whether there is air leakage at each pipe joint and pre-vacuum inside the box. Whether it has dropped, otherwise it should be repaired in time; always pay attention to whether the cooling water is unblocked; every time you drive, you should start 4-6 times intermittently, within 2s each time to overcome the large torque at startup.liquid-ring-vacuum-pump-for-Glass-Reactors

liquid ring vacuum pump Selection

As a device, the liquid ring vacuum pump is also the basis of engineering operation, so whether it works normally will directly affect the progress of the operation, so the choice of equipment is very important. In addition to its own quality, its model also needs to be considered, for everyone to better. The selection of the following, Xiaobian for everyone to put forward a little advice - on the selection of equipment:

1. Flow rate is one of the important performance data of the pump selection, which is directly related to the production capacity and conveying capacity of the entire device. For example, the normal, minimum and maximum flow rates of the pump can be calculated in the design of the design institute. When the pump is selected, the normal flow rate is based on the maximum flow rate. When there is no maximum flow rate, 1.1 times the normal flow rate can be taken as the maximum flow rate.

2. The head required for the liquid ring vacuum pump system is another important performance data of the pump selection. Generally, the head should be selected by amplifying the 5% to 10% balance.

3, liquid properties, including liquid media name, physical properties, chemical properties and other properties, physical properties are temperature c density d, viscosity u, solid particle diameter and gas content in the medium, etc., which involves the lift of the system, effective gas Calculation of the amount of eclipse and the type of suitable pump: chemical properties, mainly refers to the chemical corrosiveness and toxicity of the liquid medium, is an important basis for the selection of the pump material and the type of shaft seal.

4. The pipeline layout conditions of the equipment system refer to the data of the liquid feeding height, the liquid feeding direction, the suction side, the lowest liquid level, the highest liquid level on the discharge side, and other data and pipe specifications and their lengths, materials, pipe fittings specifications and quantities. Etc., in order to carry out the calculation of the combing process and the checking of the NPSH.Rotary-vane-vacuum-pump-in-oil-plant

5. There are many operating conditions, such as liquid operation T saturated steam force P, suction side pressure PS (absolute), discharge side container pressure PZ, altitude, ambient temperature operation is gap or continuous, pump position is fixed Still removable.

That is to say, the selection of the liquid ring vacuum pump should be considered according to the liquid delivery amount, the device head, the liquid property, the pipeline arrangement and the operating and operating conditions, so that the appropriate model can be selected, which not only improves the progress of the project, but also the device itself. Protection can extend its service life, and it is hoped that relevant workers can make the right selection.Rotary-vane-vacuum-pump-in-coal-processing

Water ring vacuum pump in paper mill

The water ring vacuum pump uses water as a medium to complete energy conversion. Water is both a working fluid and a sealing fluid. During the working process of the water ring pump, the work generates heat, which causes the working water temperature to rise, and a part of the water and gas are discharged together.vacuum-system-for-the-paper-industry

Therefore, it is necessary to continuously supply water to the pump to cool and replenish the water consumed in the pump, to maintain the formation of a normal working water ring, and to meet the working requirements of the pump. Since it is necessary to continuously replenish water, it is also permissible to bring some water from the pumped gas. In fact, the water ring vacuum pump is also widely used to pump water containing water.Roots_Vacuum_Pump

Therefore, when the water ring vacuum pump is working, in addition to water from the pump water supply line, it is also possible to feed some water from the suction port. If the vacuum pump uses a separate shaft seal external water supply line, it is also possible to flow a small amount of water from the shaft seal. This is generally the case with water ring vacuum pumps used in paper mills where water enters the pump from the pump supply line, inlet and shaft seals. The water that enters the pump from different ways does not work well as a supplemental water to meet the pump's working needs. The water that enters the pump for abnormal work will have a negative impact on the performance of the pump.liquid_ring_vacuum_pump

latest rotary vane vacuum pump

The newly developed rotary vane vacuum pump of our company is a vacuum pump equipment with compulsory oil prohibition. It solves the phenomena of oil return and injection before and is recognized by the majority of users. This rotary vane vacuum pump has the following characteristics:

1. Fully sealed structure

The C-type direct-coupled pump is the only rotary vane pump in the world that seals the motor in the oil tank. This structure will completely eliminate the possibility of shaft end leakage, and almost all rotary vane vacuum pumps in China have oil leakage problems.rotary-vane-vacuum-pumps

2. Air ballast valve with air cushion adjustment

Air cushion is an effective means of eliminating pump noise, and the function of adjustable air cushion is taken into account in the structure design of the air ballast valve of the pump. An independent system on the air ballast valve can adjust the air volume of the air cushion. In actual debugging, we obviously feel the importance of this structure for noise reduction.

3. The protection function of the pump is complete.

The pump itself is equipped with an exhaust stop valve, which is controlled by a solenoid valve, and the electric energy required by the solenoid valve is supplied by the generator with the motor. In this way, whether the motor moves or not determines whether the generator generates electricity and whether the solenoid valve operates or not. In addition, the pump also has an overload protection switch. Once the pump is stuck or overloaded, the motor current will rise abnormally. At this time, the protection switch will automatically cut off the power supply. From a usage point of view, this function is very useful.piston-vacuum-pump-structure


4. The pump has a wide range of applications.

Applicable to 50HZ, 60HZ and three-phase 220V, 380V power supply system. One of the reasons for the strong steam drainage capacity of the pump is that it can still maintain a high vacuum in the gas town. The other is that the oil temperature is high, and the oil temperature is above 80 C in normal operation. With such a high oil temperature and an effective gas town, the steam drainage capacity of the pump is greatly improved. In particular, it is worth mentioning that the pump can become a halogen-resistant vacuum pump as long as synthetic oil is selected.liquid-ring-compressor

Liquid ring vacuum pump and liquid ring compressor

The working principle of the liquid ring vacuum pump and the liquid ring compressor is exactly the same. The basic type and structure are also the same, but there are different places. In order to make everyone better distinguish the two products, the following article will explain in detail. There are five differences in the following:rotary-vane-vacuum-pumps

1, the impeller circumferential speed range is different
The peripheral speed of the impeller is mainly determined by the pressure difference between the suction chamber and the compression chamber. Since the suction pressure of the compressor is generally atmospheric pressure, and the discharge pressure of the vacuum pump is generally atmospheric pressure, the pressure difference of the compressor is large, and the required peripheral speed is also large. When the same water ring pump is used as a vacuum pump and when it is used as a compressor, the performance of the vacuum pump is different. When the vacuum pump is used as a compressor, the speed can be increased economically.

2, the optimal compression ratio range is different
The so-called optimal compression ratio, that is, the compression ratio at a higher efficiency. In general, the optimum compression ratio of a vacuum pump is higher than that of a compressor.

3, the shaft power is different
The same size of the water ring pump, the effective power when used as a compressor is larger than the vacuum pump, and the current peripheral speed of the impeller is generally selected according to the requirements of the vacuum pump, so that when used as a compressor, it is operated in an inefficient area. The required shaft power is even greater. Therefore, the power of the compressor is larger than that of the vacuum pump.piston-vacuum-pump-structure

4, the structure of the gas water separator is different
The gas-water separator of the vacuum pump is flat-topped, the overflow pipe is a common water pipe, and the top of the gas-water separator of the compressor is spherical, and the overflow pipe is controlled by a float regulating valve to prevent the water level from being below the overflow pipe. The compressed gas escapes, reducing gas pressure and effective gas volume.

5, the size of the vent hole is different
At the same size, the venting port of the compressor is smaller than that of the vacuum pump.rotary-vane-vacuum-pump-for-vacuum-coating
