Description

a kind of novel mass flow gear pump

Technical field

The present invention relates to a kind of pump, particularly a kind ofly carry various chemical mediator or oil or water or poisonous and harmful or inflammable and explosive liquid, there is a kind of novel mass flow gear pump of large discharge, High Temperature High Pressure, corrosion-resistant, acid resistant alkali.

Background technique

Current gear pump is mostly engaged each other by a pair gear and is carried liquid, feed flow is not very large, the gear pump that general peak rate of flow reaches 82L/M is just pretty good, if under the working condition requirement of large discharge (as 83-220L/M), pressure reduction 15.5bar or outlet pressure about 21bar, flow value does not substantially just reach, just cannot guarantee the effective conveying of pump, or just cannot start at all, significantly limit the application of gear pump under large discharge operating mode like this, can not meet the needs of current productive life.

Existing gear pump is mostly gear oil pump, only carry the liquid of the oils band selflubricating of low-pressure low-temperature (as about 70 DEG C) reluctantly, medium for High Temperature High Pressure and high viscosity (as 5000cP) or pole low viscosity (as 0.3cP) is just difficult to normally delivered, simple and not enough due to current design and processing, and appropriate metal and nonmetallic combined material can not be selected, for the poisonous and harmful dangerous property of volatile perishable easy crystallization and various harsher chemical mediator, substantially cannot correctly effectively carry, its using scope is limited to very much, its service precision, metering level, cycle efficiency, transmission performance, installation and maintenance are all difficult to the requirement meeting current productive life, the wearing and tearing of pump and gear are very severe, maintenance difficulty is large, user cost is high, the efficiency of pump is low, thus pump is very short for working life.

Existing gear pump is pump is connected with motor by major axis coupled mode with easy machenical coupling mostly, by gear by motor the mechanical energy that exports be converted to hydraulic energy, but this easy connection will cause the centering of Pump and Electromotor axle to ensure, thus cause pump shaft and machine to be sealed up and can be subject to unbalanced pressure, cause radial load larger, limit the raising of its pressure, be easy to cause leaking, liquid stream is not steady, pulse larger, noise is large especially, interface or pipeline etc. is made to produce vibrations, equipment is easy to damage, directly have influence on the normal service life of pump, the particularly dangerous medium of the volatile perishable easy crystallization of poisonous and harmful, the destruction to environment will be caused, the waste of resource, more serious meeting causes the injury of personnel, thus can not get extensively effective use.
