Abstract

The invention discloses a double-action plunger-type deicing liquid pump for airplane deicing liquid operation. Two plunger pump cylinders in the same structure are connected into an integral body by a crank connecting link through a piston, the plunger pump cylinders are divided into two regions, and each region is provided with a non-return valve; one power source is used for driving the two plunger pumps to work simultaneously; a liquid feed channel is connected with a liquid feed non-return valve on each plunger pump cylinder; a liquid discharge channel is connected with a liquid discharge non-return valve on each plunger pump cylinder, and the outlet of the liquid discharge channel is provided with an injection gun; and the plunger pump cylinders, liquid feed channels and liquid discharge channels are made of stainless steel. Compared with single-action pumps with the same flow rate, the double integrated pumps can raise the pressure of the injected fluid and increase the injection distance. Compared with centrifugal pumps, the frictional heat of the invention generated in the working process is very low so as not to influence the viscosity of the deicing liquid, and the invention can well maintain the characteristics of the deicing liquid. The invention is mainly used as a special pump for airplane deicing liquid for deicing and anti-icing operations.

Description

Double-action plunger type deicing liquid pump
Technical field
The invention belongs to aircraft maintenance equipment, be specifically related to a kind of aircraft be carried out the deicing operation and the dedicated pump that designs.
Background technique
Along with China's Passenger Traffic increases expansion with civil aviaton's scale, the safety pressure of aircarrier aircraft operation increases thereupon, and especially winter, Civil Aviation Airport aircraft deicing supportability deficiency was influence one of maximum hidden danger that aircraft safety moves.Discover,, as easy as rolling off a logly cause aircraft stall in take-off process to crash if the frost point of the every square centimeter of mm dia that distributes on the fuselage will cause airplane ascensional force to reduce 33%.Therefore aircraft deicing and fuselage pollute becomes the main cause that influences the aircraft security of operation winter.The aircraft deicing problem also is the principal element that causes ice and snow weather whole nation flight large size to incur loss through delay simultaneously.
The main method of aircraft deicing has spraying liquid deicing, hot air deicing, infrared rays heating deicing etc., but owing to back two kinds of methods are used separately, so the deicing cost is higher.Main at present employing spraying liquid deicing both at home and abroad, the liquid of sprinkling is deicing liquid.The main component of deicing liquid is ethylene glycol and derivative or propylene glycol, a spot of in addition corrosion inhibitor, defoamer, antioxidant, fireproofing agent, stabilizer etc.The temperature outbalance of deicing liquid is because have strict requirement to the viscosity of deicing liquid, so the temperature height all influences using effect.The too low deicing liquid of viscosity is the retention time weak point then, does not reach good deicing effect.Generally speaking, deicing liquid configures that its (temperature) viscosity all meets the requirements when the liquid storage cylinder is exported, but when the deicing liquid pump sprays, during traditional centrifugal pump work owing to, cause the viscosity of deicing liquid to reduce because of stirring action produces heat.Therefore can provide a kind of dedicated pump that does not influence the deicing liquid viscosity, reach the effect of desirable deicing, become the essential of deicing operation.
Summary of the invention
In order to address the above problem, the objective of the invention is to replace traditional centrifugal pump with a kind of double-action plunger type deicing liquid pump, guarantee the deicing effect.
Below in conjunction with accompanying drawing theory structure of the present invention is described.The plunger type deicing liquid pump of double pump unification has: crank-connecting rod, piston, plunger pumping cylinder, one-way valve etc. (as figure), its principle is by crank-connecting rod and piston two identical plunger pumping cylinders of structure to be integrated, and again the plunger pumping cylinder is divided into two zones of A, B simultaneously.Adopt a power source that two plunger pumps are worked simultaneously.The feed liquor one-way valve of two pumping cylinders and discharge opeing one-way valve are communicated with feed pathway and apocenosis passage respectively, suck deicing liquid by total feed liquor pipeline, and the deicing liquid of discharge is concentrated and is linked to ejecting gun by output pipe.The twin-tub reciprocating pump has higher working efficiency than single cylinder reciprocating pump, can effectively guarantee the continuity and the pressure requirement of atomizing of liquids.
Characteristics of the present invention and beneficial effect are:The frictional heat that plunger pump produces is in the course of the work compared very little with centrifugal pump, so can the viscosity of deicing liquid not exerted an influence, can well keep the characteristic of deicing liquid.The present invention is mainly used in the deicing to aircraft and runway, anti-icing operation as the airplane deicing dedicated pump.Can increase the deicing liquid flow adjustment range.Compare with single-acting pump under same flow, the pressure of double pump unification can raising atomizing of liquids increases bulk range, can reduce operator's labor intensity, provides the equipment support for better tackling extreme freezing weather.To improving the aircraft and the deicing of runway, anti-icing efficient, reduce airliner delay, eliminate civil aviaton's flight safety hidden danger, the quality of service that promotes China civil aviaton is significant.
Description of drawings
Shown in accompanying drawing be structural principle schematic representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing and instantiation structure of the present invention and working procedure are elaborated.As shown in the figure, two identical plunger pumping cylinders 3 of structure are connected as a single entity by piston 2 by crank-connecting rod 1, feed pathway 4 is connected with feed liquor one-way valve 5 on each plunger pumping cylinder, and apocenosis passage 6 is connected with discharge opeing one-way valve 7 on each plunger pumping cylinder.The outlet of apocenosis passage is provided with ejecting gun 8.The plunger pumping cylinder is divided into A and two districts of B, and each district is provided with an one-way valve.Consider the corrosion of deicing liquid to causing, plunger pumping cylinder 3, feed pathway 4 and apocenosis passage 6 adopt stainless steel material to make.
The working procedure of the plunger type deicing liquid pump of double pump unification is: power source starts, connecting rod drives two cylinder pistons and arrives the right limit position (shown in the dotted line) back to left movement, piston is to left movement: the deicing liquid of A district cylinder body is pushed, feed liquor closed check valve, the discharge opeing one-way valve opens of A district, left and right both sides cylinder body spray deicing liquid to the fluid pipeline at this moment; B district, meanwhile left and right both sides cylinder body produces vacuum, and the feed liquor loine pressure is greater than cylinder interior, and deicing liquid is pushed the feed liquor one-way valve open and sucked deicing liquid, and the liquid discharging valve in this district is closed.Move right behind the piston arrives left side limit position (shown in the dotted line), working principle is identical: the deicing liquid of B district cylinder body is pushed, feed liquor closed check valve, the discharge opeing one-way valve opens of B district, left and right both sides cylinder body spray deicing liquid to the fluid pipeline at this moment; A district, meanwhile left and right both sides cylinder body produces vacuum, and the feed liquor one-way valve is opened, and liquid discharging valve is closed.When discharge opeing one-way valve in two districts was opened, deicing liquid ejected with the ejecting gun of certain pressure through apocenosis passage.Connecting rod drives piston and so carries out linear reciprocating motion, and imbibition, discharge opeing process are carried out continuously, in a work cycle about two cylinder bodies draw discharge deicing liquid each twice, guaranteed the continuity that deicing liquid sprays effectively.
