Abstract
The utility model discloses a speed governor for a fan and a pump, composed of a change pole motor 1 and a change pole motor 2, a speed governor for an epicyclic gear 3, a brake 4 and a brake 8. When the speed regulation of a fan and a pump is increased, at least six available system running efficiency can be obtained via controlling the number of the pole pairs of the change pole motors 1 and 2, the switching of the brakes 4 and 8 and the synthesis of inputted rotational speed through the speed governor for an epicyclic gear 3; the system running efficiency is distributed uniformly, and outputs rotational speed in the same direction; the rank difference of the rotational speed is limited within the range of ten per cent of the maximum rotational speed of a fan or a pump; the system running efficiency realizes the control for the speed regulation of the fan and the pump.
Description
The utility model relates to the arrangements for speed regulation of a kind of blower fan and pump.
Known, in order to improve the running efficiency of system of blower fan and pump, can carry out speed regulating control to it according to manufacturing technique requirent.The current device that blower fan and pump are carried out speed regulating control has: (one) pole-changing control, it is the number of pole-pairs P that changes the asynchronous motor winding, makes the synchronous speed n of asynchronous motor
0=60f/p changes, and reaches the speed governing purpose.The motor of employing change pole motor or periodic replacement different rotating speeds is realized pole-changing control in the production.The Rate of load condensate height of motor when its advantage is speed governing operation, the power factor height, the efficient height, and reliable, easy care; Shortcoming be only be applicable to two, the differential big speed governing occasion of third gear.(2) hydraulic coupler-speed regulation, it is by the liquid transfer moment of torsion, the quantity that changes liquid realizes the speed governing purpose.Its advantage is a good speed adjustment features, can realize stepless speed regulation, and it is easy, simple to operate to start; Shortcoming is to belong to energy-dissipating type slip speed governing, and speed efficiency is not high.
The purpose of this utility model is the arrangements for speed regulation that propose a kind of blower fan and pump, solves blower fan and pump not high problem of efficient when speed governing operation.
The utility model is mainly by two change pole motors, and a planetary transmission and two breaks are formed.Two change pole motors connect with coupling with planetary transmission and two input shafts, break is installed on coupling, can move simultaneously by two change pole motors according to need of work, also can be by a change pole motor isolated operation, another change pole motor is lived with the break braking.When break was all opened, planetary transmission synthesized two rotating speeds of input, exports a new rotating speed; When an arrester close, planetary transmission carries out gearing down to the rotating speed of input, exports a new rotating speed.The number of pole-pairs by controlling two change pole motors and the folding of two breaks, can on the output shaft of planetary transmission, obtain at least 8 rotating speeds, realized blower fan and pump are carried out the purpose of speed regulating control, its speed efficiency height of change pole motor pole-changing logarithm speed governing, the power factor height, therefore the planetary transmission transmission efficiency has improved blower fan and the running efficiency of system of pump when speed governing operation up to more than 97%.
The utility model has the advantages that: (1) this device has adopted high change pole motor of speed efficiency and the high planetary transmission of transmission efficiency, so this device speed efficiency height.(2) system is simple, and is reliable, and maintenance is few.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Accompanying drawing 1 is a device schematic representation of the present utility model
Know by accompanying drawing, change pole motor 1 connects with the central gear 9 of planetary transmission 3 by coupling 5, change pole motor 2 is by coupling 6, cone gear 13 through the pair of orthogonal engagement connects with the internal gear 10 of planetary transmission 3, and the planet carrier 11 of planetary transmission 3 links by coupling 7 and blower fan or pump 12.On coupling 5, settle break 4, on coupling 6, settled break 8.When isolated operation of change pole motor, another change pole motor that does not move is lived with the break braking, and the central gear 9 or internal gear 10 brakings that also are about to planetary transmission 3 are lived.Like this, the rotating speed of importing through 3 pairs of arbitrary change pole motors of planetary transmission carries out gearing down, obtains 4 new same rotating speeds outputs that turn on the planet carrier 11 of planetary transmission 3 at least.When two change pole motors moved simultaneously, break 4 and 8 was all opened.Like this, the rotating speed of importing through 3 pairs of two pole-changing motors of planetary transmission synthesizes, and can obtain 4 new same rotating speeds outputs that turn on the planet carrier 11 of planetary transmission 3 again at least.By controlling the number of pole-pairs of two change pole motors 1 and 2, break 4 and 8 folding.Can obtain at least 8 new same rotating speed outputs that turn to through these arrangements for speed regulation.In like manner, these arrangements for speed regulation also can obtain at least 8 onesize reverse speed outputs when two change pole motors 1 and 2 inverted runnings.By the number of pole-pairs of two change pole motors 1 and 2 and the parameters of planetary transmission 3 are designed, can obtain at least 6 available same rotating speeds that turn to, make it to be evenly distributed and 10 scopes of the differential maximum speed that is limited to blower fan or pump of rotating speed in.Through these arrangements for speed regulation blower fan and pump are carried out speed regulating control, though be step speed regulation, it is enough to satisfy the speed governing requirement of production technology to blower fan and pump, the running efficiency of system when having improved simultaneously blower fan and pump speed governing.
