2BE two stage vacuum pump
There are many kinds of vacuum pumps, including single-stage vacuum pump and two stage Vacuum Pump. For example, the two stage Vacuum Pump is divided into 2be, 2BV, DLV, 2SK, Cl and so on. Each has its own advantages and characteristics. Many users are often confused when purchasing, and don’t know what this means. Let’s take the 2be double-stage vacuum pump as an example to introduce the significance it represents.
In short, 2be in the two-stage vacuum pump is a type of expression of vacuum pump, which is used to distinguish it from other products.
The 2be double stage vacuum pump adopts the structure of single stage and single action, which has the advantages of simple structure, convenient maintenance, reliable operation, high efficiency and energy saving, and can adapt to the severe working conditions such as large displacement, load impact fluctuation, etc. The impeller and the pump shaft are equipped with a thermal interference fit, with reliable performance and stable operation. After the impeller is welded, the overall operation is well heat treated, and the blade has good toughness, so that the impact resistance and bending resistance of the blade can be fundamentally guaranteed.
The 2be two-stage vacuum pump is equipped with air-water separator, and there is no exhaust port in many places. The pump cover is equipped with exhaust valve maintenance window. The clearance between impeller and distribution plate is adjusted by gland at both ends of positioning shaft, which is convenient for installation, operation and maintenance.
The model meaning of 2be double stage vacuum pump is actually named by the manufacturer in order to distinguish different kinds of products, which can help users to select the right model of products faster and improve efficiency.
2be two-stage vacuum pump is more and more widely used in daily life. After a period of use, it needs to be cleaned to avoid disassembly and assembly. Here is how to disassemble and assemble.
1, disassembly
Before removal, drain the water in the pump, and remove the separator and connecting pipe. The removal sequence of the pump from the rear end (one end without coupling) is as follows:
(1) remove the bearing housing cover, remove the pressure washer, loosen the bearing housing nut and remove the bearing housing.
(2) remove the bearing frame, loosen the gland nut and remove the gland.
(3) loosen the tension bolt and remove the rear end cover after the pump cover foot bolt is loosened.
(4) remove the pump body.
(5) remove the coupling and flat key, loosen and remove the front pressure bearing cover.
(6) take out the pump shaft and impeller from the front end cover and loosen the front bearing frame.
2. Assembly
Clean all mating surfaces, apply new oil to the bearing after cleaning, and apply new oil to the bearing seat. The assembly sequence is the reverse of disassembly. At this time, the position of the impeller in the pump body should be adjusted for installation.
The above is about the disassembly and installation steps of the 2be two stage Vacuum Pump. I believe you have a preliminary understanding of this. Pay attention to the correct installation sequence of parts in the cleaning process to ensure the normal operation of the product.
