APG technique is similar with thermoplastic injection machine. First mix resin, hardener, silicon powder and pigment by mixing plant(under vacuum), once the material finish mixing, give air pressure (2-3.5KG) to the mixing pots, so the material will be injected into mould, meanwhile, the air will release from mould when mould full filled material, material will be cured because mould is hot. The injection nozzle must continue inject material when curing.

JZJW series roots-oil-free reciprocating vacuum system comprising a roots vacuum pump as the main pump, and a WLW vertical oil-free reciprocating vacuum pump as the backing pump, the two pumps is parallel connected. These system remain the advantage of large pumping speed, which belongs to ZJP series vacuum pumps, and at the same time avoid the disadvantage of low pumping speed when it comes to high ultimate vacuum, which belongs to WLW series vacuum pumps. Thus JZJW series system is widely used in the processes of vacuum distillation, vacuum evaporation and vacuum dehydration & crystallization for chemical industry;freeze-drying for food industry; vacuum drying for pharmaceutical etc. JZJW series are fit to be used to collect gases like pentadiene,benzene, methylbenzene etc,which are anti-compressed,anti-concretion in high vacuum system. All this due to that the WLW series vacuum pumps adopted the oil-free and self-lubricating materials, then it can obtain spotless vacuum. JZJW series system are the new production developed by company and National Scientific and Reach Unit. As the ideal production to protect environment,energy-saving,small occupying of area, water-saving, low noise is the system’s main characters. 1. High ultimate vacuum, long range of vacuum 2. Large pumping speed under higher vacuum 3.Lower shaft power, small consumption 4. Without second-time water pollution, the pollution is limited in small area
Each JZJ2B series roots-liquid ring vacuum system comprising a ZJP series roots vacuum pump as main pump, a SKA(2BV/2BE1) series liquid ring vacuum pump as backing pump and other valve&measure apparatus with pips to consist the unit. The units are applied to exhausting normal gases and gases with water, organic solvents or a little dust. Compared with normal mechanical vacuum pumps, the units resist oil, steam and dust. Compared with normal water ring vacuum pumps, they have high vacuums and high exhaust speeds under high vacuum, which make the unit more fit for drying dehydration and vacuum degassing in textile, food, chemical and industry fields. Comparing with common liquid ring vacuum pump,the capacity to remain high pumping speed under high or ultimate vacuum degree becomes its main advantage. Except for normal gas suction, this system can also pump special gas with small amount of vapor or dust. Additionally, this system is free from oil pollution, as well as vapor and dust. Since the 2BV type of liquid ring pump has been adopted as its fore pump, the JZJ2B series system is more efficient than JZJ2S series (which 2SK type of liquid ring pump has been adopted). And it is compact-designed with no air leakage and high protection level. Besides,our 2BV type is more anti corrosive than 2SK type, because all 2BV impeller are albronze material. Another note, the fore pump can be designed as a closed circulation system so to reduce the environment pollution greatly. JZJ2B series system has become an ideal choice for vacuum drying or dehydration process, and vacuum degassing process in the field of light textile, food industry, chemistry, pharmacy, etc.
Working theory¡êo Its force is obtained from the power, through the rotor shaft, the eccentric vane rotating in and out of the tank, sealing air, to form the negative pressure, and use the balance of atmospheric pressure and tank pressure to inhale the liquid. 501¡¨¢284¡¨¢310¡ê¡§mm¡ê©
