With the claw type dry screw vacuum pump vacuum pump differ _

although dry screw vacuum pump and claw type vacuum pump is a vacuum pump, but due to different working principle, structural differences may occur. In order to get the lowest possible pressure, two pumps can be divided into four levels, but the claw separated by pump level and the level, while the screw water pump by the intersection of screw is separated by level. Difference between the two phases.

a, dry screw vacuum pump and the difference of claw type vacuum pump using the

1, the dry screw vacuum pump gas channel, the shortest transfer between the gas position is constant at all levels, this is good for fast discharge pump external gas, thereby reducing the gas changes and to reduce the condensate promote the discharge of solid particles in the pump. Due to the separation step, long gas channel and bend, and gas condensation easily, thus easy to block the channels.

2。 Screw vacuum pump body and rotor is a single and easy to operate. Claw type vacuum pump the pedal is almost impossible for surface treatment, and in the assembly process is also easy to damage the corrosion coating on the surface of the rotor.

two, dry screw vacuum pump and the difference of claw type vacuum pump reliability

1. Due to pedal, so cannot to integrate the rotor and the pump shaft, and rotor is installed on the shaft. For ease of installation and removal, cooperate with not too tight, so after the scroll button and loosen the operation, the rotation of the rotor is easy to occur. Dry screw vacuum pump shaft and rotor integral casting and fully integrated, no assembly problem.

2, claw type vacuum water pump has a big gap, such as the gap between the rotor and rotor, the space between the rotor and the pump body, the clearance between the rotor and the end cover and partition, each gap is independent. As long as any gap problems and pump will not work properly. Screw vacuum pump only in exhaust gaps between the client and the rotor to determine performance. The clearance between the rotor and rotor is interlinked, and high operating reliability.

3, dry screw vacuum pump and claw type vacuum water pump maintenance difference

1, remove the

claw type vacuum pump disassembly difficulty: because of using multilevel structure, all the disassembly process shall be broken down into multiple stages. The rotor disassembly is a real problem, every time remove the accuracy will be reduced in different degrees. Even the simple cleaning must be disassembled and reassembled.

dry screw vacuum pump is easy to remove, remove screw pump only need to unload the back cover bearing and take out the rotor from the front, it is very simple. If it is clean and remove, only after the cleaning will be put back into the pump rotor, without any adjustments.

2。 Install

claw type vacuum pump assembly very difficult: installing a claw pump, 4 rotor 8 clearance should be controlled rotor end face, and the clearance between the rotor and rotor is 8 rotor. If the clearance adjustment is not good, it must be redo. If you want to install the rotor shaft, it must also meet the rotor, it is easy to damage the parts. Screw pump is easy to assemble: dry screw vacuum pump assembly, just put the exhaust end clearance between the control to the screw clearance and the clearance between the exhaust wall.
