Description
Technical field
The utility model is a kind of multicolumn plug barrier film high-pressure service pump, it is a kind of plunger membrance pump that can autobalance plunger internal pressure oil, belong to the high-pressure service pump field, be applicable to that especially high-pressure delivery contains the plunger membrance pump in fields such as the medium of the flowing medium of solid particle (slurry), high-pressure delivery active sulfur body medium, high-pressure delivery thickness, high-pressure delivery seawater, high pressure painting coating.
Technical background
In production procedure such as producing, chemical industry, medicine, food, desalination of sea water, sewage treatment, purified water often need the various flowing mediums of high-pressure delivery.High-pressure service pump that can the high-pressure delivery flowing medium has plunger pump, membrane pump with pneumatic drive, plunger membrance pump etc.
Plunger pump since when using medium contact with plunger, plunger bushing, plunger and plunger jacket wall are corroded easily and are worn and torn, the gap increase causes pressure release or contamination of raw material.At present, take material to improve and heat treatment improvement and technologies such as surface spraying alloy or engineering ceramics to plunger and plunger bushing, wear resistance increases, but complex process, cost improves, and wear resistance is still undesirable.
The membrane pump with pneumatic drive delivery pressure is limited.
The plunger membrance pump is because barrier film is separated medium and pressure oil (reaching plunger, plunger bushing) fully, and plunger and plunger bushing can not corroded and wear and tear, and performance is more stable than plunger pump.Should first-selected plunger membrance pump when high-pressure delivery contains solid dielectric and Korrosionsmedium.
Existing plunger membrance pump is backward in technique, bulky, and the operation noise is big, the frequent seepage of pressure oil.Its subject matter is pressure oil leakage, barrier film fragmentation and exhaust inconvenience.One, when high-pressure work, the pressure height in the pressure oil cavity, the pressure oil that has trace oozes out from the gap of plunger and plunger bushing, will influence delivery pressure after to a certain degree, and often make barrier film stretch breakage to plunger one layback.If the pressure oil cavity internal memory of two plunger membrance pumps has gases such as air, (can not adherence pressure) just can't work.So must be before the work with the gas emptying in the pressure oil cavity.For solving this two problems, present plunger membrance pump is in the pressure oil cavity upper shed device and parts such as adding lubricating cup, pressure oil replenishment system, Decompression valves (pressure release when pressure oil is additional too much), outlet valve to be installed, so, the very complexity that pump structure is become, make the pump can only low-speed running, have to adopt big plunger in order to reach certain flow, just increased the volume and weight of pump again; The unit failure of setting up at the pressure oil cavity of high pressure takes place frequently on the one hand, has increased the probability that pressure oil leaks; On the one hand, barrier film is damaged because the pressure oil that the work of pressure oil replenishment system inaccuracy causes is very few or too much through regular meeting.
