Description
Technical field
The present invention relates to diesel engine speed regulator technical field, specifically a kind of diesel engine speed regulator Speed sensing device.
Background technology
At present, for ensureing the stable operation of diesel engine, the injection pump of diesel engine is equipped with speed regulator, speed regulator is one
Plant self-checking device, the fuel delivery of injection pump can be automatically increased or decreased according to the change of diesel load, thus realizing different negative
In the case of lotus, the confession of oil mass rises and adjusts it is ensured that the stabilization of speed of electromotor changes in the range of very little.Function pressed by speed regulator
Point have two speed governor, all-speed regulator, constant speed governer and comprehensive speed regulator, divide by revolution speed sensing have pneumatic governor,
The centrifugal and vacuum governor such as mechanical speed governor, hydraulic speed governor and mechanical-pneumatic, mechanical-hydraulic.
Mechanical speed governor is relatively broad with the application of mechanical centrifugal formula, and its structure is generally as shown in figure 1, it includes diesel engine
Camshaft 1, connector 2, push rod 3, centrifugation fly block 5, back-moving spring 7 and fuel-flow control lever 6, and it is according to spring force and centrifugation
Power balances each other and carries out speed governing, and during work, cam shaft for diesel engine 1 passes through connector 2 and drives the winged block 4 of centrifugation to rotate, and centrifugation flies block 5
Because the effect of centrifugal force is turned out for axle with being centrifuged winged block pin 4, it is centrifuged after rotating speed reaches certain speed and flies the another of block 5
By push rod 3 jack-up, compression reseting spring 7, back-moving spring 7 drives fuel-flow control lever 6 for one end, so that Fuel Delivery for Diesel Engines is reduced,
Reduce rotating speed, conversely, when diesel engine speed low to certain rotating speed when, centrifugation fly block 5 centrifugal force diminish, back-moving spring 7 resilience, drive
Dynamic fuel-flow control bar 6, increases oil mass supply, improves rotating speed, speed regulator is exactly so to automatically adjust according to speed conditions, makes diesel oil
Machine is in one section of stable rotary regimes.In FIG, generally by connector 2, push rod 3, centrifugation flies block 5, and back-moving spring 7 forms
Mechanism assembly be referred to as Speed sensing device, the Speed sensing device of this structure also has a following defect:
When the 1st, working, centrifugation flies block 5 and rotates around the winged block pin 4 of centrifugation, easily causes Speed sensing device to vibrate, centrifugation flies
The abrasion aggravation of block pin, affects the speed regulator life-span；
2nd, the foreign body such as oils and fatss, grinding enters centrifugation and flies, near block pin 4 and the winged block 5 of centrifugation, to be easily caused centrifugation and fly block 5
Can not normally be opened and closed, or centrifugation flies block 5 and is opened and closed inconsistent, leads to speed governing ineffective, or even lost efficacy.
Content of the invention
The technical problem to be solved is: provides a kind of speed governing to be quick on the draw, vibration abrasion is little, long service life
Diesel engine speed regulator Speed sensing device.
The technical solution adopted in the present invention is: provides a kind of diesel engine speed regulator Speed sensing device, including camshaft
And back-moving spring, described camshaft is socketed with the seal cavity of circular platform type, described seal cavity is built with mobile equilibrium
Medium, is provided with connecting key between seal cavity and camshaft, seal cavity and connecting key are slidably connected, the side wall of seal cavity and
At an acute angle, described back-moving spring is socketed on camshaft its center axis, one end of back-moving spring and the small end of seal cavity
Offset.
After above structure, diesel engine speed regulator Speed sensing device of the present invention due in seal cavity built with flowing
Balance media, seal cavity and connecting key are slidably connected, and camshaft drives seal cavity to rotate by connecting key, in seal cavity
The centrifugal action that is subject to of mobile equilibrium medium on the wall of side because the side wall of seal cavity and central axis are at an acute angle, from
Mental and physical efforts resolve into component forward, and when rotating speed reaches certain degree, this centrifugation component promotes seal cavity to move forward,
Pressed home spring, reduces oil mass by the regulation of fuel-flow control bar, reaches the purpose reducing speed, conversely, after speed declines,
Centrifugation component has reduced, and back-moving spring resets, and increases oil mass by the regulation of fuel-flow control bar, reaches the mesh gathering way
, mobile equilibrium media flow performance of the present invention is good, and dynamic balancing is rapid, and single unit system is quick on the draw, and solves vibration greatly, abrasion
Serious problem, increases substantially service life.
Preferably, described mobile equilibrium medium is water, hydrargyrum or sand, can effective reduces cost.
Preferably, the acute angle that the side wall of described seal cavity becomes with central axis is 350~650, it is preferred embodiment.
Preferably, the side wall of described seal cavity is provided with gusset, described gusset is extended to by the big end of seal cavity
Small end, gusset can play the effect of flow-disturbing, accelerates the self-balancing of mobile equilibrium medium.
