Overview
Performance parameter description: 1 The above table is a recommended standard series. Due to the different working conditions in actual production applications, there will be many changes in the suction gas and pressure. Therefore, when selecting, it is necessary to verify and calculate based on the actual pumping process, gas release process, condensation of condensable gases, time variation of suction pressure, etc., or refer to the existing equipment usage for selection. 2. The technical specifications of a single pump are detailed in the parameter tables of each pump. 3. Z-high suction pressure refers to the Z-high pressure at which the main pump can start. If operated for a long time above this pressure, it will cause overload of the main pump. 4. Please specify the extraction medium when placing an order
Product Details
Main features:
Roots screw vacuum unitIt is based onRoots vacuum pumpMain pump,Screw vacuum pumpFor the pumping system of the front-end pump, there is no liquid used as working fluid in the overcurrent section of this unit, and the maximum pressure is not affected by water temperature. It does not cause secondary pollution to the pumped process gas and is easy to recover the discharged gas.
JZJDP seriesRoots screw dry pump vacuum unitis caused byZJ type Roots pumpAs the main pump,DP series screw vacuum pumpAs a component of the front-end pumpDry oil-free vacuum unit.JZJDP series Roots screw dry pumpThe vacuum unit is more efficient than a single unitScrew vacuum pumpMore suitable for working under low pressure.
Due to the use of both the main pump and the front stage pumpDry vacuum pump, thereforeJZJDP series Roots screw dry pump vacuum unitHas the following main characteristics:
*There is no oil in the pump chamber, no pollution to the pumped system, and a clean vacuum can be obtained.
*There is no oil in the pump chamber, making it very easy to recover the solvent.
* Roots pumpAll cavities are treated with nickel plating,screw pumpThe pump chamber is treated with nickel plating or PTFE coating, which can remove water vapor, solvent gases, and various corrosive media.
Due to the absence of waste oil and wastewater discharge during the work process, there is no pollution to the environment.
The requirements for cooling water are relatively low. For pump cooling, ordinary circulating water can meet the requirements, and the cooling water volume is relatively small.
The main pump of the unit adopts the self-developed one by our companyZJ series Roots vacuum pumpOur company has improved the sealing between the pump chamber and the bearing chamberZJ series Roots vacuum pumpPump oil is not easily emulsified in the process of extracting large amounts of water vapor and various solvents.
The front-end pump adopts our company's self-developed technologyDP series screw vacuum pumpStable and reliable operation, due to the use of mechanical seals between the pump chamber and gear chamber,DP series screw vacuum pumpIt can still work stably without nitrogen protection.
Roots screw vacuum unitis caused byRoots pumpConnected in series with the screw pump, it is equipped with pipelines, valves, frames, and electrical control boxes. After the current stage screw pump starts working, it is controlled by a vacuum gauge head and a vacuum relayRoots pumpstart. Due to the fact that the rotating parts of Roots pump and screw pump are non-contact, the unit has the advantages of smooth operation, low noise, small vibration, compact structure, and small footprint. Usage: LuoZ-screw vacuum unitDue to its significant energy-saving effect, high vacuum area has a large pumping volume and high vacuum degree, making it an ideal pumping equipment for industries such as electrical engineering, electronic coating, smelting, heat treatment, drying, distillation, pharmaceuticals, chemical engineering, etc. Especially suitable for the semiconductor industry that requires no oil vapor pollution, as well as for occasions containing a large amount of water vapor and a small amount of dust.
