Abstract
The utility model discloses an oil immersion prevention device for an electronic speed regulation actuator of an engine. The oil immersion prevention device includes: an oil draining joint, an oil returning joint, and an oil guiding pipe. The oil immersion prevention device is characterized in that: a threaded through hole 1 is disposed at the lower part of an end cover of a center body of a high pressure oil pump, and a threaded through hole 2 is disposed on a diesel engine body at the lower part of the electronic speed regulation actuator; the oil draining joint is connected to the through hole 1, the oil returning joint is connected to the through hole 2, and the oil draining joint is connected with the oil returning joint by the oil guiding pipe, wherein pipe joints are adopted for the oil draining joint and the oil returning joint, and a copper pipe, a rubber pipe, a nylon pipe or a steel pipe is adopted for the oil guiding pipe; and thus oil accumulated in the center body of the high pressure oil pump is guided back to an oil bottom shell, oil accumulation in the center body of the high pressure oil pump is prevented, the speed regulation performance is prevented from hydraulic resistance influence formed by oil accumulation in the electronic speed regulation actuator, and engine speed regulation ineffectiveness caused by oil immersion of the electronic speed regulation actuator is avoided.
Description
Technical field
The utility model relates to anti-machine oil infuser device, is specifically related to the anti-machine oil infuser device of a kind of Motronic control maps speed regulating actuator.
Background technique
Dao Yici 226B series electronic speed governing diesel generating set is mainly used in power generation operation such as oil-gas drilling operation, shipping industry, industrial and mining enterprise, automotive industry, internal combustion power plant, residential quarter power supply.This type unit has adopted and has inspired confidence in the speed regulating control that wound ESG1000 series or ESG2000 series electronic speed regulator carry out motor.
Because the Dao Yici motor is the draining pipeline that communicates of the intermediate inner chamber setting between high pressure oil pump and electromagnetic speed-adjusting final controlling element and the external world not, intermediate is an independently confined space.After throttle tooth bar guide sleeve, cam of injection pump shafting oil leak sealing machine oil entered intermediate, the machine oil that gathers will be trapped in the intermediate housing.And, when the machine oil liquid level is higher than final controlling element tooth bar attachment hole position or the end face seal of final controlling element electromagnet when tight, a large amount of machine oil enters in the annular space of final controlling element internal electromagnetic coil and armature, unrestricted motion to armature forms flowed friction, cause electronic speed regulation final controlling element control malfunctioning, catastrophe failure such as diesel engine hypervelocity driving after engine misses, the unloaded loads when causing low engine speed tourist bus, application of load.And the maintenance man carries out the whole series with expensive electronic governing system to change, and brings enormous economic loss to the user; If do not solve the pocketed oil problem of high pressure oil pump intermediate inner accumulated machine oil, still damage easily even replace with new speed regulating actuator.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of Motronic control maps speed regulating actuator to prevent the machine oil infuser device.
The technological scheme of the utility model patent is: a kind of Motronic control maps speed regulating actuator is prevented the machine oil infuser device, comprise draining joint, back leakage connection and drainage tube, be characterized in: in high pressure oil pump intermediate end cap bottom threaded through hole one is set, at the diesel-engine body that is positioned at electronic speed regulation final controlling element bottom threaded through hole two is set, described draining joint inserts in this through hole one; Described back leakage connection inserts in this through hole two, and described drainage tube connects draining joint and back leakage connection, and wherein, described draining joint and described back leakage connection adopt pipe joint, and described drainage tube adopts copper pipe, rubber pipe, nylon tube or steel pipe; Thus, machine oil drainage oil return drain pan with high pressure oil pump intermediate inner accumulated, prevent that the high pressure oil pump intermediate from gathering machine oil, prevent that electronic speed regulation final controlling element inside from influencing the diesel engine speed regulation performance because gathering the flowed friction that forms behind the lubricant oil, stops the malfunctioning fault of engine governed speed that causes after the electronic speed regulation final controlling element is soaked by machine oil.
The beneficial effect of the anti-machine oil infuser device of a kind of Motronic control maps speed regulating actuator described in the utility model is: the utility model adopts the mode of drainage, prevent that the high pressure oil pump intermediate from gathering machine oil, stop the malfunctioning fault of engine governed speed that causes after electronic actuators is soaked by machine oil; Simultaneously, after the leakage of oil of high pressure oil pump camshaft seal, because drainage tube Oil Guide draining is arranged, need not change rubber framework grease seal, can reduce maintenance cost, improve the motor safety in utilization; The utility model cost is low, and is easy for installation, can be widely used in other motor of Dao Yici motor or similar mounting type.
Description of drawings
Fig. 1 is the structural representation of the anti-machine oil infuser device of a kind of Motronic control maps speed regulating actuator.
Embodiment
Referring to Fig. 1, shown in: a kind of Motronic control maps speed regulating actuator is prevented the machine oil infuser device, is made of draining joint 5, back leakage connection 7 and drainage tube 6; During installation, drill through hole one at the minimum point place, bottom of high pressure oil pump intermediate end casing 3, and make internal thread with the screw tap strand; Drill through hole two at the diesel-engine body 8 that is positioned at electronic speed regulation final controlling element bottom, note avoiding cylinder block cylinder sleeve water channel position and body gusset position, make internal thread with the screw tap strand; Pipe joint respectively adds one of copper washer respectively as draining joint 5 and back leakage connection 7 to get two of pipe joints, and wherein a pipe joint screws in the internal thread of through hole one, and the another pipe joint screws in the internal thread of through hole two, and pipe joint screws up with a wrench; Drainage tube 6 with copper, steel, rubber or nylon material connects draining joint 5 and back leakage connection 7 again, thus the lubricant oil that accumulates in the high pressure oil pump intermediate 2 is drained into diesel engine oil pan 9, prevent that effectively high pressure oil pump intermediate 2 from gathering machine oil, prevent that electronic speed regulation final controlling element 4 inside from influencing the diesel engine speed regulation performance because gathering the flowed friction that forms behind the lubricant oil, stops the malfunctioning fault of engine governed speed that causes after the electronic speed regulation final controlling element is soaked by machine oil.
After the installation, start the diesel engine running in.Pull down the peep hole plug screw on high pressure oil pump intermediate 2 tops in the operation process, insert the liquid level height of checking up Engine oil in the high pressure oil pump intermediate 2 with thin wire from peep hole, answer the inorganic oil accumulation phenomena; Surpass 10cm if gather the machine oil liquid level height, the camshaft seal leakage of oil that then proves high pressure oil pump 1 is too serious or the oil return caliber is too small, should strengthen the internal diameter of drainage tube 6 and draining joint 5, back leakage connection 7 or the camshaft seal of replacing high pressure oil pump 1, guarantee that the high pressure oil pump intermediate does not gather lubricant oil.
