Abstract
An electric hydraulic driving thruster consists of a motor which is arranged at one end of the thruster, a fuel pump impeller which rotates coaxially with the motor and a plug which is positioned in the same cylinder with the fuel pump impeller. A disk-shaped fuel valve and a fuel valve seat are arranged between the fuel pump impeller and the plug; the other end of the motor is equipped with a coaxial fan. The fuel pump impeller is sealed with the rotor room of the motor with ceramic seal. The electric hydraulic driving thruster relating to the utility model has 10 to 120 seconds fall delay or 1 to 3 second rising delay; and the rising and reducing range of the temperature of the fuel is less than 20 centigrade; therefore, the utility model is applicable in the belt conveyer and other devices of long-term conveyance and suitable in the working temperature environment of 50 centigrade.
Description
The utility model relates to a kind of electro hydraulicthruster, and it is by the fuel pump impeller of the motor that is arranged on pusher one end and motor coaxle rotation, and and the plunger that is configured in the same clutch release slave cylinder of fuel pump impeller form.Belong to pusher technology in the operation field.
Electro hydraulicthruster is the driving element of break, is the component part that the belt transport heavy is wanted and since belt comveyer long-term between the continuous operation characteristics, cause matching used electro hydraulicthruster temperature rise too high.Rubber seal is very easily aging in the pusher, makes whole pusher reduce more remarkable working life.In addition, in machine works such as belt comveyer, require the lifting of pusher that delay function should be arranged in addition.
The purpose of this utility model promptly is the above-mentioned deficiency at prior art, and provides a kind of in long time continuous working that the pusher temperature rise is low, the complete machine long service life, and rising or falling the electro hydraulicthruster that possesses delay function in the work.
Above-mentioned purpose of the present utility model realizes by following technical measures.
At fuel pump impeller by motor that is arranged on pusher one end and motor coaxle rotation, and and fuel pump impeller be configured in the electro hydraulicthruster that the plunger in the same clutch release slave cylinder forms, one dish type fuel tap and fuel tap seat are set between fuel pump impeller and plunger, dispose coaxial fan at the other end of motor.
The power hydraulic pressure of employing the utility model technology pushes away advises device, because dish type fuel tap and fuel tap seat are set between fuel pump impeller and plunger, when fuel pump impeller rotates, the oil pressure that increases promotes the dish type fuel tap, rise rapidly, cause the variation of oil flow channel, change oily flow, reach the effect that the time-delay rising promotes plunger.Otherwise, when adopting between different fuel tap seats and the impeller configuration of oily discharge orifice road, when the fuel pump impeller stall, because partly oily discharge orifice road is stopped up by the dish type fuel tap, originally promote the oil of plunger, slowly flow back to, play the decline time-lag action through other oil duct (dividing oilhole stream).Fan with the coaxial rotation of rotor, the heat radiation refrigeration is played in work temperature rise to motor, this not only keeps good insulation performance favourable to the motor of long-time continuous operation, main is the reduction of electric machine temperature rise, brought the reduction of oil temperature in the operating cylinder, each of having exempted pusher be the disadvantage that lost efficacy of the premature aging of O-ring seal, rubber cushion etc. partly.And if the fuel pump impeller between centers of the coaxial rotation of rotor sealing adopts the ceramic seal body to carry out plane sealing, then can make motor ventilating fan not have leakage of oil, oil impregnate, and it is sticking dead by oil that fan can not take place, and makes fan lose due effect because of rotor chamber.
Electro hydraulicthruster provided by the utility model, can be by being arranged on fuel pump impeller and work dish type fuel tap and the oil flow channel that changes mutually of fuel tap seat between plunger, can obtain to have the 10-120 time-delay that descends second, the perhaps rising of 1-3 second time-delay, the temperature rise of oil reduces by 20 ℃, is fit to the electro hydraulicthruster product of 50 ℃ of ambient temperature work.
Accompanying drawing is the structural representation of electro hydraulicthruster provided by the utility model.Wherein Fig. 1 is the electro hydraulicthruster that possesses the decline delay function, and Fig. 2 is fuel tap, fuel tap seat and the adjacent motor that possesses the electro hydraulicthruster of rising delay function, and the work plunger is sectional view partly.Below in conjunction with accompanying drawing,, further narrate technical characteristics of the present utility model by preferred example.
Embodiment one
Electro hydraulicthruster, by the motor that is arranged on pusher one end (2), with the fuel pump impeller (4) of motor coaxle rotation, and and the plunger (8) that is configured in the same clutch release slave cylinder of fuel pump impeller form.One dish type fuel tap (5) and fuel tap seat (7) are set between fuel pump impeller (4) and the plunger.Fuel tap seat (7) is except having the oil-through hole road, also dispose the guiding trepanning (10) of the guide pillar (11) of dish type fuel tap, have in the middle of the dish type fuel tap (5) and slide guide pillar (11), the clutch release slave cylinder inner wall arrangement has when dish type fuel tap (5) falls after rise and the annulus (12) of its outer driving fit.Bottom arranged coaxial at motor (2) has fan (1), and shaft sealing takes ceramic seal spare (3) to carry out plane sealing between fuel pump impeller (4) and rotor chamber.In the fuel tap seat part of clutch release slave cylinder, configuration oil separator (6) provides dish type fuel tap (5) to fall and inwall annulus (12) driving fit way to cycle oil.Have speed governing on the oil separator (6) and revolve post (9), be used to adjust oil separator oil opening size, control oil speed reaches the purpose of adjusting the decline delay time.
Embodiment two
Present embodiment is a kind of rising time-delay electro hydraulicthruster.The part-structure schematic representation, as shown in Figure 2.
Among this embodiment, guide pillar (13) in the middle of being provided with in the fuel tap seat (7), and the middle hole of sliding that has guide pillar (13) of dish type fuel tap (5).Fuel tap seat (7) is except partly disposing the oil circuit through hole over against fuel tap, and the part that is hidden by fuel tap at the end also is provided with oily circulation flow path.This fuel tap and fuel tap stand structure, make when fuel pump impeller rotation, oil pressure rising, after fuel tap (5) is lifted and hides fuel tap seat (7) top oil circuit through hole, oil rises through the oil circuit through hole that is not being hidden and promotes plunger, because fuel tap seat partly oil circuit hole is hidden by fuel tap, oil stream slowly reaches the time-delay purpose that rises.
