Description
Technical field
The utility model relates to a kind of torque converter, is specifically related to a kind of cleaning for torque converter, purification plant.
Background technique
Improve gradually to the environmental requirement of engineering machinery domestic and international market particularly EU market, particularly comparatively strict to reliability, noise, emission control.Torque converter is because its impact is little, gear shift is steady, easy to operate being widely adopted in all kinds of engineering machinery, and this speed changer is mainly made up of several parts such as torque-converters, fluid clutch, oil feed pump, main control valve, casing, torque-converters housings.
It is that pollution due to transmission oil product causes fault greatly that the torque converter using on fork truck at present has, so will clean it before it dispatches from the factory, test.But the controlling method adopting at present is conventionally for being to clean each component before assembling, and do not clean after assembling, directly carry out delivery-inspection test, qualified can dispatching from the factory.This kind of mode has following several respects defect:
1. component do not clean up, and the pollutant producing in assembling process of the test also cannot effectively be removed;
2. after having tested, the transmission oil in speed changer cannot drain, and torque-converters inside is the remaining transmission oil being polluted in a large number still, directly brings entrucking operation into, causes car load transmission system turbidity test to decline;
3. dispatch from the factory property test platform after using after a while, need thoroughly to clean fuel tank, change test oil product, the oil product of changing is as waste oil disposal.This causes operator's daily maintenance amount of labour large, and oil product is discarded and caused environmental pollution, and experimentation cost is risen.
Model utility content
The utility model, in order to solve the problems of the technologies described above, provides a kind of cleaning for torque converter, purification plant, torque converter is thoroughly cleaned, and clear gusoline reclaims, thereby reduces its fault, improves the turbidity test of car load transmission system.
The technical solution of the utility model is: a kind of cleaning for torque converter, purification plant, comprise torque converter and filler tank, the oiler of described torque converter by gear pump be connected with filler tank, oil outlet is connected with transfer fuel tank by front oil pump; Described transfer fuel tank is connected with the filler opening of purification plant, and the oil outlet of described purification plant is connected with transfer fuel tank, filler tank respectively; Between the oil outlet of described purification plant and transfer fuel tank, be provided with the first solenoid valve, between the oil outlet of purification plant and filler tank 9, be provided with the second solenoid valve; In described transfer fuel tank, be provided with liquid level relay.
Further, described the first solenoid valve is connected with described liquid level relay with after the second solenoid valve parallel connection; Opened and closed by setting requirement by these two solenoid valves of liquid level relay control; Described the first solenoid valve is normally closed solenoid valve, and the second solenoid valve is normally open solenoid valve.

In the utility model, the first solenoid valve is connected with liquid level relay with after the second solenoid valve parallel connection again, and wherein the first solenoid valve is normally closed solenoid valve, and the second solenoid valve is normally open solenoid valve.In the time that in transfer fuel tank, transmission oil reaches setting height, liquid level relay switches on power, and the second solenoid closure is started working, and the first solenoid valve disconnection is not worked; In the time that in transfer fuel tank, transmission oil is lower than setting height, liquid level relay deenergization, the first solenoid closure is started working, and the second solenoid valve disconnection is not worked.
Torque converter adopts quantitative oil filling device to inject appropriate transmission oil before delivery test, and the test such as conventional load, zero load of dispatching from the factory.After delivery test completes, keep torque converter to remain in operation, starting oil product displacement cleans: first start forward and backward oil pump, by gear pump, by clean transmission oil, by the first one-way valve, the oiler from filler tank from torque converter injects in torque converter constantly; Opening conduits valve, is evacuated to the contaminated transmission oil in fluid power in transfer fuel tank by its oil outlet by front oil pump simultaneously.In fluid power, the cyclic permutation number of times of transmission oil reaches the cycle-index of regulation or after cycle time, can stop forward and backward operation of oil pump.
In the time that liquid level relay in transfer fuel tank detects that transmission oil oil level in transfer fuel tank is lower than setting height, start the first solenoid valve, close the second solenoid valve, in transfer fuel tank, transmission oil carries out circularly purifying by purification plant, and has ensured the circularly purifying of transmission oil.In the time that the oil level of liquid level relay detection transfer fuel tank in transfer fuel tank reaches setting height, switch on power, through certain hour time delay, start the second solenoid valve, close the first solenoid valve, the transmission oil after purification plant purifies in transfer fuel tank is injected to filler tank and recycle.Until the oil level of transfer fuel tank while being down to low level, being restarted the first solenoid valve, closed the second solenoid valve, continue to carry out oil purification work.
In the time that this device has fault to overhaul, pipeline valve and manually operated valve are closed, torque converter is isolated, can overhaul the oil circuit at its rear portion, and the oiler of fluid power is connected and circulates with oil outlet.
So the utlity model has following beneficial effect:
1, the utility model is by replacing cleaning to the transmission oil in torque converter, effectively remove the each component of torque converter and before assembling, thoroughly do not cleaned up the pollution bringing, also removed the pollution that torque converter produces in assembling process of the test simultaneously; Thereby it is up to standard and cause speed changer initial failure, vehicle to maintain first problem in advance thoroughly to have solved after torque converter delivery test turbidity test; Avoid the inner remaining contaminated oil product of torque-converters to affect car load transmission system turbidity test.
2, transmission oil displacement is automatically carried out and without manual intervention, has been improved operation convenience;
3, this device, according to the situation that is rinsed torque converter, can be set transmission oil slow rinse flow and washing time, may extend in other speed transmission test devices, and popularization degree is high.
The contaminated oil of 4, torque converter being carried out to extract in cyclic permutation cleaning process is passed through, after the purification plant filtration, purifications such as high pressure oil filter, to form free of contamination test oil, and automatic cycle is to filler tank.Fluid recycles in whole process of the test, has saved test oil cost, and produces without discarded oil product, has reduced environmental pollution.In addition, also save the work of daily cleaning fuel tank, reduced labor intensity.
