Description
One, affiliated field:
The utility model belongs to the hydraulic technique field, but a kind of crushing roll energy-conserving hydraulic device of pressure regulation particularly.
Two, background technology:
In hydraulic means or system's running, as in hydraulic pressure clamping and tensioning apparatus or system, after the execution oil cylinder is finished clamping, the demand of hydraulic oil has not needed substantially, as long as keep the amount of leakage of each parts, keep certain pressure to get final product, and the increase of the energy consumption that the pumping plant running brings, the wearing and tearing of hydraulic unit cause the shortening of component life.Because long-term operation brings the variations in temperature of oil, the instability of bringing to pressure and need often to adjust.Therefore, in present hydraulic means or system's running, particularly in vegetable oil pressing machine hydraulic pressure clamping and Hydranlic tensioner or system, after the execution oil cylinder is finished clamping, hydraulic oil has not needed substantially, as long as keep the amount of leakage of each parts, keep certain pressure, this device or system are under dead-tight state in other words, motor pump almost seldom running every day, general running every day is no more than one minute, in this case, how to realize that pressure regulates, how to control the motor pump running and stop, keeping remaining some hydraulic oils in the plunger cylinder and the fixed and decompression not of pressure in holdout device or system weighing apparatus, is the problem that presses for solution to satisfy that different oil plants require the adjusting of pressure.
Three, summary of the invention:
The purpose of this utility model is, situation to the pin prior art, design provides a kind of and can control the running of motor pump and stop, the motor pump discontinuous running, can not produce the pressure reduction that oily temperature height causes, thereby reduce fault rate, the service life of improving associated components, safe and reliable, but and the crushing roll energy-conserving hydraulic device of inspection and pressure regulation easy to adjust.
The utility model is realized by following manner: but a kind of crushing roll energy-conserving hydraulic device of pressure regulation, comprise the stop valve 12 that is provided with on the pipeline between motor pump 10 and the check valve 9 that is communicated with it and hydraulic jack 11 and check valve 9 and the hydraulic jack 11, it is characterized in that: on check valve 9 between motor pump 10 and the hydraulic jack 11 and stop valve 12 pipelines, the plunger type accumulator is set, as shown in Figure 1.
Said plunger type accumulator is made up of oil cylinder 1 and plunger 2, connecting rod 3, lever 4, magnetite 7 and dry-reed relay 6, adjustable heavy stone roller 5 and overflow valve 8, wherein, the front end of lever 4 and centre are hinged with connecting rod 3 and oil cylinder 1 respectively, the rear end of lever 4 is connected adjustable heavy stone roller 5 and magnetite 7 and dry-reed relay 6 respectively with the rear portion, as shown in Figure 1.
Adjustable heavy stone roller 5 in the said plunger type accumulator and lever 4 adopts and is threaded, and reaches the pressure regulation purpose thereby move forward and backward by the adjustable heavy stone roller 5 of the adjustable heavy stone roller 5 of rotation (centre bore of adjustable heavy stone roller 5 is a screw connection structure) realization, as shown in Figure 1.
Operation principle of the present utility model and process are: design adopts lever heavily to cut or polish jade with an emery wheel adjustable plunger type accumulator structure, with reed switch relay 6 control plunger type accumulators, motor pump 10 shuts down when plunger 2 rises to high point, when plunger 2 drops to certain altitude, motor pump 10 starts, when plunger 2 running lofty perch rear motor oil pumps 10 stop.Rotating adjustable heavy stone roller 5 (centre bore of adjustable heavy stone roller 5 is a screw structural) realizes that adjustable heavy stone roller 5 moves forward and backward and reaches the pressure regulation purpose, increase or reduce the pressure of plunger 2, thereby realize the pressure adjusting, satisfy of the adjusting requirement of different oil plants to pressure, plunger 2 moves up and down the magnetite 7 on the band lever 4, thereby control dry-reed relay 6 opens and closes, and the running of control motor pump 10 and stopping to keep remaining some hydraulic oils in the oil cylinder 1 of plunger 2 and keep the fixed and decompression not of pressure weighing apparatus in the system.This system is under the dead-tight state of system, motor pump almost seldom running every day, general running every day is no more than one minute, so this plunger type accumulator structure reduces the pumping plant energy consumption greatly, normally tradition is moved 1/1440 of pumping plant energy consumption continuously, does not improve the build-up of pressure reduction because discontinuous running can not produce the oil temperature, thereby significantly reduces the former rate of system, and the service life of improving associated components, can be widely used in similar continuous clamping control hydraulic means or the system.
