Abstract
The utility model relates to an unloading warehouse-sweeping pump of a self-controlled groove tanker, which comprises a conveying pump and a front-mounted controller. The front-mounted controller comprises a tank body; the top of the tank body is provided with an exhaust valve; the inside of the tank body is provided with a liquid level sensor; the tank body is provided with a medium outlet; and the suction opening of the conveying pump is connected with the medium outlet of the front-mounted controlled in an air tightness way. The conveying pump and the front-mounted controller operate under the protection of the liquid level sensor, thereby preventing the equipment damage due to the regular exhaustion of other pumps, and even the serious defects causing major fire accidents. The utility model prolongs the operational life of the equipment, and reduces the maintenance times.
Description
Technical field
The utility model relates to a kind of unloading sweeping store pump for self-control tank car.
Background technique
Groove tank car de-ballast pump is one of capital equipment of liquid medium groove tank car unloading conveying, is widely used in industry departments such as oil, chemical industry, electric power, metallurgy, environmental protection, sewage treatment, food, pharmacy, synthetic fiber, mining, papermaking, building.In the spron tank car unloading at present there be the technological measure of extensive use:
Self-priming pump: its working principle is after utilizing the air wrapped folder that will suck in the inner cyclic process of medium under the effect of pump that prestores in the pump chamber in the pump chamber to discharge, the ability proper functioning, and its shortcoming is that period of exhaust is long, efficient is low.Medium unloading is inflammable, have very big disaster hidden-trouble during the medium of explosive easy vaporization.
Displacement pump: displacement pump comprises plunger reciprocating pump, diaphragm pump, Roots pump, screw pump and gear pump etc.So operational efficiency is low low, easy to wear working life greatly because of its friction system.
Centrifugal pump: use centrifugal pump spron jar to need the vacuum pump subsidy, in the unloaded operation,,, need repeated multiple times to use vacuum pump that gas is discharged the centrifugal pump work of restarting again so pump can't continuous operation because of the vaporization of medium attraction process.
The common defects that above-mentioned technological measure exists also has: 1, must someone guard the Control work process in the equipment operation, will cause aneroid idle running damage equipment as careless slightly, as unloading is that therefore inflammable, explosive medium also can lead to fire accident; 2, medium unloading back is residual bigger, and consequent economic loss is very big.
Summary of the invention
The purpose of this utility model provides a kind of advanced technology, and is stable, the unloading sweeping store pump for self-control tank car of unloading medium noresidue.
The technological scheme that adopts is:
Unloading sweeping store pump for self-control tank car, comprise transfer pump and preposition controller, described preposition controller comprises tank body, the top of tank body is provided with outlet valve, at least be provided with a liquid level sensor in the tank body, offer media outlet on the tank body, carry pump intake to be connected with the media outlet tightness of preposition controller.
The medium inlet of above-mentioned preposition controller is arranged on the top of tank body, and place, medium inlet tightness is connected to suction pipe.
The medium inlet of above-mentioned preposition controller is arranged on the bottom of tank body, and the place, medium inlet is connected with suction pipe.
Working principle:
1, following inhalation type (unloading of groove tank car lower exit valve):
A) suction pipe that tightness is connected unloading sweeping store pump for self-control tank car suction port place is tightly connected to groove tank car unloading valve place, opens valve.
B) connect unloading sweeping store pump for self-control tank car automatic control box power supply, be arranged on the automatic vent opening of valves on preposition controller top this moment, medium enters preposition controller and carries pump chamber at atmospheric pressure effect lower edge connecting tube in the groove tank car.
C) enter medium liquid level in the preposition controller when rising to the liquid level sensor start-up point that is arranged in the fore-lying device automatic control pressure vent close, transfer pump starts operation and medium is delivered to the output pipe network that is tightly connected with the transfer pump outlet.
D) medium that exists in the groove tank car pumps the back air and enters preposition controller along suction pipe, and transfer pump stopped when the medium liquid level dropped to the liquid level sensor halt in the preposition controller, and unloaded operation finishes.
2, go up inhalation type (unloading of groove tank car top jar mouth):
A) at the bottom of the suction pipe (oil filling riser) that tightness is connected unloading sweeping store pump for self-control tank car suction port place vertically is inserted to jar by groove tank deck mouth.
B) the preposition controller spout of unloading sweeping store pump for self-control tank car is outwarded winding, after preposition controller and conveying pump chamber were filled with, (fill with when using equipment first, need not later on to annotate again) screwed the spout tightness again.
C) connect unloading sweeping store pump for self-control tank car automatic control box power supply, start the transfer pump operation.Preposition controller memory medium is sent to output pipe network by delivery outlet under the transfer pump effect, produce vacuum in the preposition controller this moment, and medium enters preposition controller at atmospheric pressure effect lower edge suction pipe in the groove tank car.
D) medium that exists in the groove tank car pumps the back air and enters preposition controller along suction pipe, and transfer pump stopped when the medium liquid level dropped to the liquid level sensor halt in the preposition controller, and unloaded operation finishes.
Advantage of the present utility model:
A) omnidistance of work need be pressed total start button to end-of-job and be need not manual operation again.
B) operating accuracy is accurate, and autostop was transferred the medium noresidue when medium was inhaled sky, the fund that saves material (relying on gas-liquid delivery device and advanced liquid level sensor control).
C) equipment running process does not have powerful mechanical compress, does not have disaster hidden-trouble during therefore inflammable in suction, explosive medium.
The operation under liquid level sensor protection of transfer pump and preposition controller has overcome the operation of often finding time of other pump causes device damage, even causes the major defect of fire disaster accident.Prolong the equipment operation life-span, reduced maintenance frequency.
