Party A: Product Description (Industrial Gas Pumps)
Industrial gas pumps are mainly used for air separation products: filling of liquid oxygen, liquid nitrogen, liquid argon, liquid carbon dioxide, air supply systems, the units are mainly single row, double row and three-row reciprocating pumps. Refer to each parameter table for specific parameters.
Its flow is 300~5000L/H and its maximum exit pressure is 35.0mpa.An electromagnetic adjustable speed motor or a fixed rotating speed motor or a variable frequency and variable speed motor or an explosion proof motor or an explosion proof variable frequency motor can be equipped as per actual requirements.
Instructions for installing units:
a.The pump inlet shall be close to the storage tank to the greatest extent.
b.From the pump to the storage tank, the liquid inlet and air return pipeline shall be kept upward sloping to make the air inside the pipeline return to the storage tank, Reverse U-shaped” elbows are prohibited in the liquid inlet pipeline, and U-shaped” elbows are prohibited in the air return pipeline.
c.Ball valves or brake valves shall be used for the liquid inlet pipeline and the air return pipeline. Stop valves shall not be used. Elbows shall be reduced to reduce pipeline resistance.
d.Thermal insulation shall be performed for the liquid inlet pipelines and facilitate operation, a liquid outlet/air outlet pressure interlocking device with automatic control can be equipped.
e.After the reciprocating pump is operated for 600hours,the motor direction can be changed to make the transmission case rotate in a reversed direction so as to enhance the service life of the transmission case.
Party B: Product parameters (Carbon Dioxide Pump Series)
1.Scope of application
a.Such pumps are mainly used for liquid carbon dioxide.
b.Filling of carbon dioxide liquid cylinders.
c.Air supply, air distribution systems.
2.Main technical parameters
b.Maximum exit pressure:10.0mpa
A.JB/T 9076 Specifications for reciprocating cryogenic liquid pumps
B.GB/T 9234 Power Reciprocating Pumps
a.Stationary motor/electromagnetic speed regulation/frequency control
b.Safety valve/cryogenic stop valve
c.Back temperature interlocking device
d.Air outer temperature interlocking device
e.Liquid outer pressure interlocking device
a.The precooling is fast, which makes it not easy to form dry ice inside the pump.
b.The simple pump head module design facilitates maintenance.
c.The pump has the design of new type gland packing and ultra-long service life.
d.Maintenance is convenient, it merely takes two hours to perform a routine maintenance.
e.The pump can be continuously operated for 24 hours.
