2BV Water Ring Vacuum Pump Model

Before using, we should first determine the type of 2BV water ring vacuum pump to determine whether it is the product we need. Different models of the corresponding use of equipment will also have a certain difference, choose the right model can help use. If the model is incorrect, it will not work properly.

1. According to the technological parameters of the device, the physical and chemical properties of the conveying medium and the structural characteristics of our products and the suitable working position, we can decide which series of pumps to choose.

2. Then determine the rated flow rate of 2BV water ring vacuum pump.

3. Determine its rated lift.

4. Then the rated motor of 2BV water ring vacuum pump is determined.

5. Looking at the type spectrum of the selected series of pumps, which type of frame should the flow rate and head fall into, we can preliminarily determine the selected type. Usually, under different rotational speeds, one type may be selected.

6. Check the performance curve of the preliminary selected model and check whether the NPSHr of the pump meets the requirement of NPSHa of the device.

7. Check the performance curve to verify whether the rated working point of the selected model falls in the effective working area of the pump. Comparing the efficiency, speed (lower speed, longer service life) and price of the pump comprehensively, the model of 2BV water ring vacuum pump is determined.

Roots Vacuum Pump Advantages and Characteristics

Roots vacuum pump has the advantages of fast start-up, low power consumption, low operation and maintenance cost, fast pumping speed and high efficiency. It is insensitive to a small amount of water vapor and dust in pumping gas, and has a high pumping rate. It can quickly remove water vapor and dust within the pressure range of 100-1 Pa. Suddenly released gases. The pressure range is just between the oil seal mechanical vacuum pump and the diffusion pump. Therefore, Roots vacuum pump is often connected in series between diffusion pump and oil seal mechanical vacuum pump to improve the pumping capacity within the range of intermediate pressure. At this time also known as mechanical booster pump.

Roots vacuum pump runs smoothly with low noise, low vibration and high vacuum limit. Because the transmission part of the pump adopts reliable clearance elimination structure, the pump can work under high pressure difference for a long time. It can start quickly and reach the limit vacuum in a short time. Because there are no sliding parts in Roots vacuum pump chamber, no lubricating oil is needed to avoid the pollution of oil vapor to the system. Roots vacuum pump is safe and reliable, ZJH, ZJP Roots vacuum pump series itself with safety valve, play an automatic protection role. Roots vacuum pump has compact structure and small floor area. Left, right and lower exhaust ports can be selected to facilitate user installation.

Roots vacuum pump is widely used in vacuum metallurgy of chemical, food and pharmaceutical industries, such as smelting, degassing, rolling, vacuum distillation, vacuum concentration, vacuum drying, etc.

Vacuum Pump Brief Introduction

With the wide application of vacuum technology in various fields, such as industrial production, national defense, military industry and scientific research, a variety of vacuum acquisition equipment, also known as vacuum pumps, have emerged in industry.

Generally, it can be defined as a device that produces, improves and maintains a vacuum state in a closed space connected by tones in an appropriate way. With the rapid development of vacuum technology application, the working principle, shape and application environment of vacuum acquisition equipment have been developed in a variety of ways. For example, the pumping speed range of pumps has risen from zero to hundreds of thousands or millions of liters per second.

According to different working principles, vacuum pumps can be divided into two types: gas delivery pumps and gas trapping pumps. Among them, the gas pump includes: liquid ring vacuum pump (water ring vacuum pump), reciprocating vacuum pump, rotary vane vacuum pump, fixed vane vacuum pump, slide valve vacuum pump, cycloid vacuum pump, dry vacuum pump, Roots vacuum pump, molecular vacuum pump, traction molecular pump, compound vacuum pump, water jet vacuum pump, gas jet pump. Jet pump, steam jet pump, diffusion pump, etc. Gas trapping pumps mainly include: adsorption pumps and low temperature pumps.

Water Ring Vacuum Pump Unit Understanding

The characteristic of water ring vacuum pump unit is to realize suction, compression and exhaust by changing the volume of pump chamber, so it belongs to variable volume vacuum pump. So what are its characteristics and performance? Let's take a look together with Xiaobian. After all, if you want to use the unit well, you must first understand its performance characteristics.

1. The structure is simple, the manufacturing accuracy is not high, and it is easy to process.

2. Inhalation uniformity, stable and reliable operation, simple operation and convenient maintenance.

3. The compressed gas in the water ring vacuum pump unit is basically isothermal, that is, the temperature change of the compressed gas is very small.

4. Because there is no metal friction surface in the pump chamber, there is no need to lubricate the pump, and the wear is very small. The sealing between the rotating part and the fixing part can be accomplished directly by the water seal.

5. Compact structure, high speed pump, generally can be directly connected with the motor, without the need for deceleration device. Therefore, with a small structure size, we can get a large amount of exhaust gas and occupy a small area.

Operation Technology of Vacuum Pump Unit

There are various types of vacuum pump units, each of which has its own functional characteristics, but most of the units have the same operation technology, mainly divided into two types: intermittent and continuous. So in order to make you better understand the operation process of the unit, the following is a detailed introduction by Xiaobian for you, let's take a look at it.

1. Intermittent operation process: This operation process relies on manual up-down or back-and-forth swing of the cover, which determines that the size of the vacuum chamber should not be too large. Only when the vacuum cap is closed, the vacuum pump unit will operate, while the other time units will not work. The advantage of this operation mode is to reduce power consumption and noise, but this requires that the quality of the unit must be too hard. If the quality of the unit is not up to standard, the vacuum pumping will be very slow and the vacuum effect is not good for a long time to use. Therefore, customers should not blindly look at the price and ignore its quality when purchasing the vacuum pump unit.

2. Continuous operation process: the cylinder controls the automatic swing cap, and the cylinder provides pressure to the vacuum cap through the vacuum pump unit, so the unit has been in operation, but because the use requirements are strengthened on the board and the whole machine skeleton, the size of the unit is larger than the unit.

Therefore, when using the vacuum pump unit, we can choose more suitable operation technology according to the operation requirements of the unit and the actual conditions of field use, so as to better play the functional effect of the unit, so as to make the operation of the unit more stable and long-term.

2H Slide Valve Vacuum Pump

From the use point of view, 2H sliding valve vacuum pump is suitable for pumping air and other general gases. When using air ballast, it can also suck a small amount of condensable gases (such as water vapor). Additional devices should be installed when pumping gases with excessive oxygen, explosive, corrosive to ferrous metals and chemical reaction to vacuum oil. The pump can be used alone or as a front-stage pump of high vacuum pumps such as diffusion pump, oil booster pump and Roots pump. Compared with rotary vane vacuum pump, 2H sliding valve vacuum pump is more durable and has long service life. The pump is widely used in vacuum coating, vacuum heat treatment, vacuum sintering, molecular distillation and aviation simulation test.

From the product characteristics, 2H sliding valve vacuum pump is optimized weight, less vibration and low noise; bearing seal chamber is supplied separately from pump chamber to avoid premature damage of bearing and seal caused by impurities entering bearing chamber; according to user requirements, auxiliary oil tank can be attached to achieve the function of cooling vacuum oil to separate impurities; Except for the old H-150, the motors are all above the pump, compact in structure and occupy less space.
