Description
Technical field
The utility model belongs to mechanical engineering field, relates in particular to a kind of cleaning device that is used for hydraulic drive pipeline system.
Background technology
Hydraulic drive is a kind of kind of drive that adopts liquid to transmit energy and control as working media, and it carries out work by the hydraulic oil circulating transfer energy that is enclosed in the pipeline.Because it has " volume is little; in light weight ", " can be in given range automatic stepless regulate hauling speed " reposefully, " can realize the conversion of operating mechanism's rotation and straight reciprocating motion " and plurality of advantages such as " it are little wear and tear; long service life ", has obtained application widely at industrial equipment with in installing more conveniently.Say that in a sense the height of hydraulic transmission technical merit has become one of important symbol of weighing a national industrial development level height.
Because flow in the hydraulic system pipeline and pressure can change at random in real work, thereby produce hydraulic shock in various degree, this impact shake is fallen impurity such as oxide skin on the pipeline inner wall, welding slag, make it to sneak in the hydraulic oil, make hydraulic system contaminated, can have a strong impact on the operate as normal of Hydraulic Elements and hydraulic system.
According to statistics, in hydraulic system, about 80% fault is that systemic contamination causes., just need the pipeline of hydraulic system effectively be cleaned, to guarantee the operate as normal of hydraulic system for this reason.Hydraulic system pipeline cleaning way commonly used at present is to use the oil strain cleaning equipment, and hydraulic system pipeline is connected with the oil strain cleaning equipment, utilizes the wash oil of cleaning equipment to circulate in pipeline, takes away impurity.Because the pressure of this oil strain cleaning equipment is low, flow is bigger, and function singleness only can be removed the impurity that is suspended in system's hydraulic oil, be difficult for the obstinate dirt (as oxide skin and so on) attached to pipeline inner wall is effectively cleaned, so cleaning performance is undesirable.
In addition, the dedicated hydraulic system pipeline cleaning equipment that more domestic units develop voluntarily, be by high velocity liquid stream the dirt impurity that adheres on Hydraulic Elements and the pipeline inner wall to be washed, removes, its cleaning performance is to rely on flow velocity (generally requiring flow velocity greater than the 10 meter per seconds) size of cleaning fluid to guarantee.Therefore, this detergent line equipment need provide the wash oil that flow is big, pressure is high, and for the system of 20～30 millimeters of pipe diameters, required motor power reaches 100～200kW, has so both made the cleaning equipment heaviness, has increased energy consumption again greatly; In addition, will be aided with the tube wall that manually constantly knocks hydraulic system pipeline in cleaning process, whole cleaning process generally will continue 1～2 round the clock.In a word, the cleaning efficiency of this hydraulic system pipeline cleaning equipment is poor, and scavenging period is long, and labour intensity is big, and power consumption is big and versatility is poor.
The day for announcing is on November 15th, 2000, and notification number is to disclose a kind of " Water-hammer type hydraulic system pipeline cleaning equipment " in the Chinese utility model patent of CN2405671Y, and it mainly contains return filter, fuel tank, the oil suction filter, motor, stop valve, duplex gear pump, check valve, reversal valve, valve piece, laser detector, overflow valve constitutes.During real work, hand-operated direction valve in the cleaning equipment opens/closes flushing channel with certain frequency, in the hand-operated direction valve opening-closing process, produce " water hammer " phenomenon, the hydraulic shock that utilizes " water hammer " phenomenon to produce is used for improving cleaning performance, make scavenging period shorten to 2～3 hours round the clock from original 1～2, not only reduce operating personnel's working strength, also increased substantially cleaning performance and labor productivity.
In cleaning practice, find,, need provide different cleaning flows, and for the pipeline of different length, then need " water hammer " frequency of providing different, could guarantee cleaning performance and operating efficiency for the pipeline of different-diameter.
For the caliber that adapts to pipeline in the different hydraulic systems better and/or the variation of length, guarantee cleaning performance, improve cleaning efficient, be necessary said apparatus is further improved.
