Abstract
The utility model relates to a liquid unloading linkage device and belongs to the technical field of liquid delivery. The utility model adopts a technical scheme that the liquid unloading linkage device comprises a buffer tank (1), a liquid level sensor (2), a liquid level controller (3), a delivery pump (7), a delivery pump power supply operator (5) and a linkage regulation valve (4), wherein the buffer tank is arranged in front of an inlet of the delivery pump and is provided with the liquid level sensor; the linkage control valve is arranged at an outlet of the delivery pump; the liquid level sensor is connected with the liquid level controller; and the liquid level controller is respectively connected with the linkage control valve and the delivery pump power supply operator. The liquid unloading linkage device has the positive effect that in the liquid unloading process, in particular to at the liquid unloading later stage, when the liquid supply is not enough, the linkage regulation valve at the outlet of the pump can be automatically closed, so that the occurrence of evacuation phenomenon is avoided, the delivery pump is protected, and the liquid loss and the risk are reduced; and the design is reasonable, the delivery pump can be effectively protected, the maintenance expense is reduced, the unloading work of a plurality of liquid tank cars can be simultaneously performed, and meanwhile, the personnel allocation is reduced.
Description
Technical field
The utility model relates to a kind of liquid linkage of unloading, and is used to the automatic adjusting control of the process of unloading, and can protect the discharge pump of unloading, and belongs to liquid conveying technology field.
Background technology
At present, the liquid manual operation Control Flow that adopt of unloading more, it is untimely and cause vaccuum phenomenon operation to occur through regular meeting, very big to the damage of pump, and unloads many cars simultaneously, and many people's operations must be arranged, and has caused the waste on the manpower.Though the buffer action of surge tank is arranged,, operates untimely if flow control is bad; Still vaccuum phenomenon can often appear; Cause the parts damages of discharge pump, cause the leakage of liquid, cause the waste of course of conveying material; Particularly when inflammable, explosive, poisonous liquid is unloaded, also formed the unsafe factor in the course of conveying.And present anti-evacuator; Described in patent No. 200510083953.X, adopt the water-level detecting probe, utilize the electric action of water to detect the submersible pump working water level; And operating circuit is set; Thereby the switchgear of control submersible pump, but the method is not suitable for the process of unloading of flammable and combustible liquids, and the method is because the frequent unlatching of discharge pump also is the infringement to pump.
The utility model content
The utility model purpose provides a kind of liquid linkage of unloading; Simple in structure, safe and practical, easy to operate; Saving personnel configuration, maintenance cost are low, can guarantee in the process of unloading import amount of liquid hour, avoid vaccuum phenomenon occurring because of liquid runs out of; Cause damage, solve the problems referred to above that exist in the background technology pump.
The technical scheme of the utility model is: a kind of liquid linkage of unloading; Comprise surge tank, liquid level sensor, fluid level controller, discharge pump, discharge pump power operation device and interlock control valve are provided with surge tank before the discharge pump import; Surge tank is provided with liquid level sensor; The discharge pump outlet is provided with the interlock control valve, and liquid level sensor is connected with fluid level controller, and fluid level controller links to each other with discharge pump power operation device with the interlock variable valve respectively.
On surge tank, also be provided with visor, be convenient to observe; Carry delivery side of pump that the manual adjustments valve also is set.
When liquid is unloaded operation when carrying out, discharge pump outlet manual adjustments valve standard-sized sheet is by the liquid level of surge tank liquid level sensor monitoring buffering pot liquid; Pass to fluid level controller; Valve opening degree is reconciled in interlock by the outlet of fluid level controller control discharge pump, keeps normally and unloads, when arriving minimum liquid level; The generation of vaccuum phenomenon is avoided in the termination of pumping of control discharge pump power operation device.
When automatic control system goes wrong, also can operate through surge tank visor and centrifugal pump outlet manual adjustments valve.
The utility model adopts fluid level controller to regulate discharge pump outlet interlock and reconciles valve opening, to guarantee the discharge pump even running, prevents to find time; And close to an end when unloading, when liquid level dropped to minimum liquid level, fluid level controller control was from the termination of pumping of discharge pump power operation device; Guarantee the continuous operation of discharge pump; Thereby effectively avoid the appearance of vaccuum phenomenon, play the effect of protection centrifugal pump, the stable of process that guarantee to unload carries out.
The good effect of the utility model is: in later stage especially in the operating process of unloading, when liquid occurring when under-supply, can turn down the pump discharge interlock automatically and reconcile valve; Guarantee the continuous operation of pump; Avoid the generation of vaccuum phenomenon, the protection discharge pump reduces loss of material and danger.The utility model is simple in structure, reasonable in design, can effectively protect discharge pump, reduces maintenance cost, can carry out the discharging work minimizing personnel configuration simultaneously of many tank cars simultaneously.
Description of drawings
Accompanying drawing 1 is the utility model embodiment synoptic diagram;
Among the figure: surge tank 1, liquid level sensor 2, fluid level controller 3, interlock control valve 4, discharge pump power operation device 5, visor 6, discharge pump 7, manual adjustments valve 8, liquid inlet opening 9, vent port 10.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further through embodiment.
A kind of liquid linkage of unloading; Comprise surge tank 1, liquid level sensor 2, fluid level controller 3, discharge pump 7, discharge pump power operation device 5 and interlock control valve 4 are provided with surge tank before the discharge pump import; Surge tank is provided with liquid level sensor; The discharge pump outlet is provided with the interlock control valve, and liquid level sensor is connected with fluid level controller, and fluid level controller links to each other with discharge pump power operation device with the interlock variable valve respectively.On surge tank, also be provided with visor 6, liquid inlet opening 9, vent port 10, carry delivery side of pump that manual adjustments valve 8 also is set.
The course of work: the liquid level of liquid level sensor 2 monitoring surge tanks 1; Pass to fluid level controller 3 then, the aperture that fluid level controller 3 is regulated interlock control valve 4 automatically according to liquid level, thus the assurance process of unloading is carried out stably; If the liquid level of surge tank 1 is reduced to below the minimum liquid level that is provided with; Then control 5 terminations of pumping of discharge pump power operation devices, thereby effectively prevent the pump depletion phenomenon, the protection discharge pump by fluid level controller 3.
