Abstract
The utility model provides a high-pressure water coupler stepless speed regulating device. One end of a reduction box is connected with a motor connected with a programmable logic controller (PLC), the other end of the reduction box is connected with a lead screw through a coupling, the lead screw is provided with a nut and is fixed below a chute through two supporting seats, and the but is connected with a slide plate which is movably connected with the inside of a slide rail of the chute. A hydraulic cylinder is fixed on the slide plate through a connection seat, a hydraulic cylinder piston rod is connected with a hydrodynamic coupling scoop tube, rotary speed output by the motor is changed by a coupler, and the speed transmitted to a descaling pump can be adjusted according to actual requirements. The slide plate and the chute structure can achieve rapid loading or unloading, the positions of the slide plate and the chute can be fine adjusted through the lead screw and the nut, and the stepping motor is controlled by the PLC, and automatic fine adjustment is achieved. Therefore, the descaling pump can operate in a relatively low-speed and low-pressure state, energy is greatly saved, spare part consumption is reduced, and operation stability of the system is guaranteed.
Description
Technical field
The utility model belongs to the machinery field, relates in particular to the used hydraulic couplers stepless speed-regulating device of a kind of high-pressure water descaling system.
Background technique
High-pressure water descaling system is one of key equipment of steel rolling production-line, and the power consumption of high-pressure water descaling pump is very large, is discontinuous operation system, generally adopts hydraulic couplers as loading or the no-load running of conservation measures control descaling pump.In using at the scene, because the type selecting nargin of descaling pump is greater than on-the-spot actual the use, make actual operating mode depart from declared working condition, therefore the scene generally takes the mode of valve throttle to regulate, and namely increases the method for the drag losses of rising pipe by closing minor valve.The method makes large energy be consumed in the valve loss, and is not only economical not, and causes the vibration abrasion of valve, and descaling pump also moves under high pressure conditions, also can aggravate the damage of relevant device.At present, the high-pressure water descaling system hydraulic couplers mainly is to carry out speed governing by an oil hydraulic cylinder that is connected with the hydraulic couplers scoop tube, oil hydraulic cylinder is connected with PLC, action by the aerial oil hydraulic cylinder of PLC, therefore can only regulate in the larger context, more among a small circle or claim that stepless speed regulation then can't realize.
Summary of the invention
The utility model aims to provide a kind of mechanical transmission and automatically control combination, realizes the dynamic adjustments to high-pressure water descaling Coupler transmission speed, thereby reaches energy-conservation, consumption reduction, the high pressure water Coupler stepless speed-regulating device of stable system operation.
For this reason, the solution taked of the utility model is:
A kind of high pressure water Coupler stepless speed-regulating device comprises oil hydraulic cylinder and PLC, it is characterized in that, is comprised of motor, speed reducer, coupling, slide plate, chute, screw, leading screw and supporting base; Speed reducer one end connects with the motor that is connected PLC, the other end connects the leading screw with screw by coupling, leading screw is fixed on below the chute by two supporting bases, screw is connected on the slide plate, slide plate is movably connected in the slideway of chute, oil hydraulic cylinder is fixed on the slide plate by connecting base, and hydraulic cylinder piston rod is connected with the hydraulic couplers scoop tube.
The beneficial effects of the utility model are:
The utility model mainly is to regulate the speed control principle that internal work oil ring thickness is adjusted output speed by scoop tube according to hydraulic couplers, increase the device with intense adjustment scoop tube hydraulic cylinder travel or position at scoop tube, realization is to the stepless speed regulation of Coupler, thereby make the rotating speed of motor output after the Coupler speed change, the speed that is delivered to descaling pump just can be regulated according to actual needs at any time.Adopt slide plate, chute structure that the oil hydraulic cylinder traveled distance of control Coupler speed governing scoop tube is controlled, can carry out fast load or unload.By the position of leading screw, screw trace adjusting slider chute, by PLC control step motor, realize automatic precision refinement adjusting.
The utility model can make descaling pump move under the state of relative low speed, low pressure, thereby can greatly save the energy, reduces spare parts consumption, guarantees the stable of system.
