Five, embodiment:
The sludge pump technology with regard to its structure and performance, mainly is divided into three parts: pumping system, hydraulic system and electrical system.
Pumping system of the present invention adopts double dynamical, drives the hydraulic-pressure pump group respectively, makes pumping work more powerful, and system is more reliable.Electrical system adopts the PLC programmable control system, has prolonged time between failures.Hydraulic system is provided with main oil pump pressure cut off and safety valve double security device.Effectively raise the reliability of complete machine.The present invention is an example with MPS330 type sludge pump.
With reference to the accompanying drawings 1,2,3,4, the power plant and the pumping system of sludge pump of the present invention are relatively independent, and the two large divisions adopts hydraulic pipe line to connect.The power plant of forming sludge pump by underframe 1, preceding cover frame 2, diesel fuel tanks 3, side door 4, hydraulic oil container 5 and diesel engine 6 by mechanical coupling.The pumping system of forming sludge pump by pumping underframe 7, conveyor piston 8, distribution oil cylinder 9, hopper 10, master cylinder 11, washing chamber 12 and conveying cylinder 13 by mechanical coupling.Power plant provide hydraulic energy and the operation by electric system control pumping system to pumping system.Power plant are done toward complex line by the master cylinder 11 of hydraulic system and electric system control pumping system and are pushed and draw back motion, the conveyor piston 8-that master cylinder 11 drives mechanical connection rises and pushes and draw back, make the high viscosity mud of the pbz polymer solid particle in the hopper 10 be inhaled into and carry cylinder 13, simultaneously opposite side is carried the high viscosity mud in the cylinder to be transported to discharge port by S pipe distributing valve.Distribute oil cylinder 9 to drive S pipe distributing valve and the action of master cylinder 11 synchronous coordinations by mechanical connection.Do action and so forth, the high viscosity mud in the hopper 10 is transported to discharge port continuously.Between washing chamber 12 and hopper 10, guaranteed intensity and firm with the pull bar connection.Hopper 10 adopts the streamline design, has improved the suction of carrying cylinder 13.The present invention designs for " fetching earth in the inland sea " encloses extra large operation, and pumping system and power system are taked the split design, is convenient to arrangement in the maintenance of equipment and the cabin.
With reference to the accompanying drawings 5, (arrow points is the mobile direction of hydraulic oil), the present invention adopts two motors to drive two cover oil pump groups respectively, two main oil pumps interflow amount reaches 870 liters/minute, opens ball valve 20 at the oil pump oil outlet to installing respectively between the valve group, and the oil pump group can singly be overlapped use, also can collaborate to use, when cover power plant break down, only need close this table oil pump group to the unlatching ball valve between the valve group, another set of power plant still can work independently.Both satisfy the demand of high pressure, big discharge capacity, improved pumping system master's reliability again.While is the actual conditions of quantity delivered as required, and decision uses a cover or two cover power to come work, has played energy-conservation effect.
With reference to the accompanying drawings 6, design of Hydraulic System of the present invention is an open type double loop hydraulic system, reduces the reversing impact of hydraulic system.
Two main oil pumps 16, theoretical output flow reach 870 liters/minute, and the hydraulic oil of so big flow inevitably produces bigger hydraulic shock when electro-hydraulic reversing valve 15 commutations, influence the working life of main oil pump 16, electro-hydraulic reversing valve 15 and Sealing.Technology that the present invention has designed a kind of " commutation emission reduction ", when the piston rod of master cylinder 11 will be withdrawn into the oil cylinder bottom, commutation inductor 14 detects the position signal of master cylinder 11 piston rods, be transferred to PLC programmable controller 21, PLC programmable controller 21 reduces the output current of proportional electromagnetic valve 17, proportional electromagnetic valve 17 is under the effect of right-hand member spring force, spool is moved to left, spool is in right position, proportional electromagnetic valve 17 two ends oil circuit conductings, main oil pump 16 outlet pressure oil eject through the piston rod of proportional electromagnetic valve 17 with piston cylinder 19, cause swash plate 18 angles of inclination to reduce, (because the angular dimension that swash plate tilts, directly the output of decision oil pump flow is how much), the purpose that output flow reduces when reaching electro-hydraulic reversing valve 15 commutations makes the surge pressure of oil return reduce to 1.8MPa by original 3MPa.Described PLC programmable controller is the commercially available prod, the 6ES7214-1AD21-0XB0 type PLC programmable controller that adopts Siemens to produce.The present invention is not described further.Main oil pump 16, proportional electromagnetic valve 17, swash plate 18 and piston cylinder 19 are formed the oil pump groups, adopt the A11VLO190LRDU2 model oil pump group of German BOSCH-REXROTH company.Main oil system system employing double pump of the present invention interflow, big flow is exported, and has guaranteed the commutation number of times of long stroke master cylinder 11, has satisfied the requirement that high pressure, big discharge capacity are exported.The big capacity accumulator of oscillation system utilization makes 9 swings of distribution oil cylinder strong to distributing oil cylinder 9 fuel feeding, guarantees super large, the commutation of overweight S valve rapidly, reliably.
If the initial of main oil pump 16 beginning emission reduction certainly will influence the output flow of main oil pump 16 too early, lower efficiency, as the time after reaching the effect that reduces impact peak value late.In order accurately to determine the time, when the present invention's design will be withdrawn into the oil cylinder bottom at master cylinder 11 piston rods, detect the position signal of master cylinder 11 piston rods by commutation inductor 14, after detecting signal, signal is transferred to PLC programmable controller 21, PLC programmable controller 21 output orders, reduce the output of control ratio solenoid valve 17 electric currents, thereby reduce the output flow of main oil pump 16, after treating that electro-hydraulic reversing valve 15 commutations finish, main oil pump 16 output hydraulic oil are through transposition back electro-hydraulic reversing valve 15, the piston rod of withdrawal master cylinder 11 bottoms is released, commutation inductor 14 detects the position signal of master cylinder 11 piston rods once more, is transferred to PLC programmable controller 21 again, PLC programmable controller 21 output orders, scaling up solenoid valve 17 electric currents output at once, the output flow of main oil pump 16 is to maximum.When load test, determined the movement velocity of master cylinder 11 piston rods, finally measured zero-time.
Electrical system of the present invention adopts the PLC programmable control system. Hybrid power system of the present invention, two main oil pump output dress Put with the single-power system of prior art, single oil pump device and compare, intelligent degree is higher, works alone between the element, no Interfere with each other; Twin diesel has kept rotating speed consistent.
Product of the present invention has showed the advantage energy-conservation, efficient, intelligent, that labor strength is low in running job, at big model That encloses encloses the seawater profit, and sludge is carried in the operation, and it will be promoted and use widely.
