1, the ultimate pressure of the vacuum pump
The unit of pump's extreme pressure is PA. This means that the pump is equipped with a standard test cover at the entrance and operates according to the specified conditions, and it tends to a relatively stable low pressure without introducing the normal operation of the gas.
2. Pumping speed of vacuum pump
Pump pumping rate unit is M3/S or L/S. It means that the pump is equipped with a standard test cover, and when working according to the specified conditions, the flow rate of gas flowing from the test cover is measured at the specified position of the test cover. Pressure ratio. Referred to as pumping speed.
3, vacuum pump suction
Vacuum pump suction unit is PA M3/S or PA L/S. It refers to the gas flow at the pump inlet.
4, the starting pressure of the vacuum pump
The starting pressure unit of the vacuum pump is PA, which refers to the pressure when the pump starts without damage and has suction action.
5, the pump pressure
The pre-pressure unit of a vacuum pump is PA, which refers to the outlet pressure of a vacuum pump whose exhaust pressure is lower than one atmosphere.
6, the vacuum pump before the pressure
The vacuum pump port front-end pressure unit is PA, which means that it exceeds the previous-stage pressure that can damage the pump.
7. Large working pressure of vacuum pump
The large working pressure unit of a vacuum pump is PA, which refers to the inlet pressure corresponding to a large pumping volume. At this pressure, the pump can work continuously without deterioration or damage.
8, compression ratio
Compression ratio refers to the ratio of the outlet pressure of a pump to a given gas to the inlet pressure.
9, Ho's coefficient
The ratio of the actual pumping speed above the area of ​​the pumping pumping passage to the theoretical pumping speed calculated by molecular effusion.
10, speed factor
The ratio of the actual pumping speed of the pump to the theoretical pumping speed calculated by molecular effusion at the pump inlet.
11, return flow rate
The unit of return flow rate of the pump is G/CM2.S. It refers to the mass flow rate of the pump flow per unit area of ​​the pump inlet when the pump is operating in accordance with the specified conditions.
12, water vapor allowance
The allowable amount of water vapor is KG/H, which refers to the mass flow of water vapor that can be pumped out by the gas ballast pump under continuous operating conditions under normal environmental conditions.
13, large allow water vapor inlet pressure
The inlet pressure unit for large allowable water vapor is PA. It refers to the high inlet pressure of water vapor that can be pumped out by the gas ballast pump under continuous ambient conditions.

High-pressure Desorption Electrolysis


This series of equipment is oriented to the gold-loaded carbon in the gold cyanide carbon slurry process for gold desorption and electrolysis, and the gold adsorbed on the gold-loaded carbon is produced in the form of high-grade gold mud.

This series of equipment has 3 patented technologies and 5 proprietary technologies. Sodium cyanide is not used in the desorption liquid, which reduces the lean carbon grade below 100g/t. The key technology of this equipment is to ensure the balance of metal content, avoid the phenomenon of equipment "accumulation" and "floating gold", and ensure the stable and stable technical indicators of the equipment. The cost is low, and the content of technological advancement has been broadcast on the Spark Science and Technology column of CCTV in 2000. The technology passed the technical appraisal in 2003 and won the second prize of Science and Technology of the China Gold Association. The overall technical level is domestically leading. In 2006, it was designated as an energy-saving technology for gold production by the National Development and Reform Commission. In 2007, it was designated as an industry standard equipment by the National Development and Reform Commission. The equipment has obtained 3 Chinese patents, the patent numbers are: 01241537.5 01241538.5 200620029209.1
