Boshan Roots vacuum unit, Roots water ring vacuum unit, official Acer Pump (certified merchants)

Reasonable choice based on metallurgical gas pump: vacuum metallurgical equipment, in the cold oven pre-pumping and air source heat state smelting generally are: ① is pumped air space (with pumped volume related) jzjs Roots vacuum unit, ② Process gas released during (including generation and gas introduced with time, ju degree, pressure and production technology related), ③ exposed surface in a vacuum outgassing (with material type, surface area, time, temperature and pressure, etc. related), ④ leakage into and gas permeation (leakage rate of system components, equipment, dynamic and static sealing member is related to the quality of welding and structural materials), ⑤ material vapor pressure caused by the volatile gases (with temperature and pressure related). To ensure the needs of metallurgical processes, design of the vacuum system is required for the gas flow extraction of all the above, to choose the right variety of vacuum components - pumps and valves, according to the arrangement of the pumping process reasonable solutions to achieve pumping pumped gas space, to overcome deflation and leak Roots vacuum unit selection, the vacuum chamber has always been able to maintain the desired vacuum. Roots vacuum pumps in the medical application of vacuum freeze-drying the frozen vacuum is a better way to present the material dehydration, which can be freeze-dried substance Roots vacuum unit, previously frozen, then at low temperature and pressure conditions in which substance sublimation of water to achieve the purpose of dehydration. Sublimation of water vapor condensation method adopted to collect. After this material after vacuum freeze dry operation, it becomes a matter of dehydration. After substances, enzymatic action of vacuum freeze-drying weak after the original chemical, physical performance is essentially the same, the dried material was porous structure, volume is essentially the same, easy recovery. Especially it is good that substances vacuum freeze-drying, can be stored for years without deterioration. The condenser is used to condense water vapor sublimation equipment, its work overflow of up to -45 ℃ ~ -60 ℃, the cold source is provided by two 2F6.3 type of freon refrigeration unit. Vacuum dryer unit consists of two 2X-5 rotary vane vacuum pump and a mechanical ZL-8 Roots type mechanical booster pump components. Vacuum unit through the vacuum line and vacuum valves, etc. are connected with the oven, condenser, constitutes a sealed vacuum systems. Vacuum unit equipped with a vacuum gauge electrical contacts, according to a pre-selected vacuum degree position, automatic control Roots pump start. Vacuum line between the oven and the condenser is equipped with a vacuum valve, you can always switch according to requirements. Bottom of the condenser tube equipped with a branch road leads to the hot air, the butterfly valve 50 partitions, the role of this valve and the branch pipe for condenser defrost drying purposes, Roots pump vacuum manifold above, alone When using a mechanical vacuum pump passage fitted with a solenoid valve, when the Roots pump starts, this width is automatically turned off. Vacuum line, equipped with electrical tape bleed valve, when the pump is stopped automatically turn off the vacuum line double Roots water ring vacuum unit, while the air into the pump, vacuum pump oil to avoid the action due to the negative pressure into the vacuum line. Equipped with a vacuum pump connected between the corrugated hose line, in order to prevent vibration transmitted to its operation member. Boshan Roots vacuum unit, Roots water ring vacuum unit, official Acer Pump (certified merchants) are provided by Acer Pump Co., Ltd. Zibo Shi. Boshan Roots vacuum unit, Roots water ring vacuum unit, official Acer Pump (certified merchants) Zibo Shi Wang Pump Co.
