Description
Technical field
The present invention relates to a kind of cooling system, this cooling system comprises pumping unit, filter element, cooling and control unit and the measuring cell that adopts integration mode to connect.
Background technique
Adopt in the power-transmission system work systems such as (for example gearboxes of automobile) of hydraulic oil as lubricant medium in the hydraulic system (for example mill type cylinder of hoist) of utilizing the pressure energy or other, its medium that adopts is hydraulic oil normally.Hydraulic oil be exactly utilize fluid pressure can the hydraulic medium that uses of work system, in work system, play effects such as energy transfer, system are lubricated, anticorrosion, antirust, cooling.For hydraulic oil, at first should satisfy work system under operating temperature with start-up temperature under to the requirement of fluid viscosity, because the hydraulic pressure oil viscosity changes directly relevant with hydraulic operation, transmission efficiency and transmitting accuracy, also requires the viscosity temperature characteristic of hydraulic pressure oil viscosity and the demand that shear stability should be satisfied system.
Yet, in above-mentioned work system, temperature rising along with environment in the work system, the temperature of hydraulic oil also increases, and the rising of hydraulic fluid temperature not only causes weakening of its function that system is cooled off, and the hydraulic pressure oil viscosity decreases, and its function such as lubricated to system also should have significantly mutually and weakens.In fact, all there is such problem in the work system of every employing hydraulic oil as lubricated and cooling medium.For preventing above-mentioned hydraulic oil heat up the hydraulic oil cooling that causes and the reduction of lubricating function, method commonly used in the prior art is at specific work system, and the mode of employing " extracorporal circulatory system " is cooled off the hydraulic oil in the work system.The mode of so-called " extracorporal circulatory system ", promptly as shown in Figure 1, at the outside interim independently cooler 5 that connects of work system, and the suction pump 3 that drives by motor 4 of temporarily arranging in pairs or groups, cooler and suction pump all place on the carriage 6 temporarily, this suction pump adopts connection flexible pipe 1 to be connected with cooler, be used for from work system 2 suction hydraulic oil to cooler, hydraulic oil aspirates out via suction pump from work system, the cooler of flowing through obtains cooling, the pressure difference that produces when cooled hydraulic oil aspirates via pump again is back in the work system, has recovered the cooling of hydraulic oil and lubricated normal function thus.
Yet, adopt the above-mentioned type of cooling to have problems.At first, such type of cooling can't satisfy the monitoring of the temperature and pressure in the whole cooling system and demand for control.Because the cooling power of cooling system can not realize that 100% accurately mates with the particular job system, therefore need monitor the temperature of the hydraulic oil in the cooling system, when if the temperature of hydraulic oil wherein has been lower than its certain lower limit of bringing into play cooling and the required normal temperature range of lubricated function in work system, need suitably to regulate cooling system, its cooling power is reduced, otherwise influence hydraulic oil on the one hand cooling and lubricating functions normally are provided in work system, also causing the waste of cooling power on the other hand, in fact also is the energy and even cost waste.Simultaneously, because the power of suction pump also can not be realized 100% accurate rational Match with specific cooler, even the power of suction pump is a bit larger tham the proper functioning capacity of cooler, also can cause the pressure in the cooler to increase gradually along with the growth of cooler operating time, in time handle if fail, can cause final pressure to surpass the ability to bear of cooler, and cause cooler to be damaged.And when the power of suction pump during less than the proper functioning capacity of cooler, the working efficiency of cooler certainly will be affected, and since the relatively large volume of the big working efficiency decision of cooler do not utilized fully, thereby cause the waste of working space.
Secondly, also there is the problem of more time selection of needs and the different parts of coupling in the settling mode that above-mentioned prior art provides.When selecting cooling unit for specific work system, select temporarily and mate suitable suction pump, cooler and relevant connection instrument (as flexible pipe, flange, hose coupling and hard pipe joint etc.) according to the prior art needs, this need expend more time and efforts, and even so also exists final relevant device of selecting and parts to exist not match more greatly and have a strong impact on the problem of using effect.
Summary of the invention

Embodiment
Fig. 2 is the schematic representation of cooling system of the present invention.Wherein, motor M in the pumping unit 1 drives the outlet suction hydraulic oil of suction pump P from work system 9, motor M can be current known any Wechselstrommotor, and suction pump P can be a kind of in centrifugal pump, pneumatic pump, axial-flow pump, mixed flow pump or the volute pump.
Can adopt common flexible pipe to connect between pumping unit 1 and the work system 9.
Via the hydraulic oil of the pumping unit 1 suction filter element 2 of at first flowing through.Filter element can adopt current known net formula hydraulic oil filter or stacked hydraulic oil filter as filter element, and preferably has a plugged filter indicator, the effect of filter be will be via pump P suction and the part physical particles contamination precipitation in the hydraulic oil that comes in filter, with the pipeline in the anti-plugging cooling system, and the pure degree that further assurance is back to the hydraulic oil of work system 9 meets cooling and lubrication needs.The effect of plugged filter indicator A is that when the impurity level that retains because of filtration in the filter acquired a certain degree, alert was cleaned filter, to guarantee follow-up filtering effect.Between the cooling and control unit 3 of filter element 2 and pumping unit 1 and back, between cooling and control unit 3 and the measuring cell, all adopt between measuring cell and the work system 9 current known mechanical connection manner (such as the awl rib-loop is connected, flange connects or the plain bolt connection) be tightly connected.
Further flow through cooling and control unit 3 of the hydraulic oil that filters through filter cools off.Cooling and control unit can adopt current known water-cooled cooler or air type cooler as cooling element, cooling and control unit integrate cooler and distributor exactly, reserve the measuring equipment connection interface on cooling and the control unit and are used to connect instrumentations such as thermometer, pressure meter.The pipeline of the cooler that hydraulic oil is flowed through has the water or the air of preferred reverse flow outward, because water or air are as cooling medium, it is compared with hydraulic oil to be cooled has the bigger temperature difference, therefore the heat of hydraulic oil is passed in the cooling medium via its pipeline of flowing through, and therefore its temperature is minimized in the process of cooler of flowing through..
Preferably, filter element 2 built-in bypass valve, when causing hydraulic oil not flow through filter when the filter obstruction, filter bypass valve is opened, make hydraulic oil walk around filter element and flow directly into cooler, to prevent owing to plugged filter causes cooling system hydraulic oil loop termination, finally cause the temperature rise of working equipment oil, influence proper functioning.
For realizing that the hydraulic oil flow of flow through cooling and control unit 3 is through measuring cell B to the temperature of the hydraulic oil that is about to be back to work system 9 and the pressure control of cooling system.Preferably, measuring cell B comprises thermometer 7, is used to measure the temperature through the hydraulic oil of supercooling and control system.Thermometer can be current known gas thermometer, resistance thermometer, thermoelectric thermometer, radiation thermometer or flash ranging thermometer.
