Abstract
The utility model discloses a diesel engine oil pressure automatic stop device checker, comprising a pressure vessel tank, an air in pipe, an exhaust pipe, a needle gate valve, an oil pipe and a pressure meter; wherein, the pressure vessel tank is a high pressure sealed container, the needle gate valve is arranged on the air in pipe and the exhaust pipe, which are communicated with the pressure vessel tank, the pressure vessel tank is filled with engine oil, a bottom of the oil pipe is inserted into the engine oil in the pressure vessel tank and the pressure meter is positioned at an oil pipe outlet. The utility model can confirm the protected lowest engine oil pressure of the diesel engine oil pressure automatic stop device through the compression and decompression. The utility model solves the difficult problem of incapable of on site verification due to the long-life performance of the diesel engine oil pressure automatic stop device, so as to ensure the normal operation of the diesel engine.
Description
Technical field
The utility model relates to a kind of diesel engine oil and forces down the automatic stop device calibrator.
Background technique
The effect of low fuel pressure automatic stop device is when engine oil pressure is lower than minimum authorized pressure, stops diesel engine work automatically, causes a serious accident because of insufficient lubrication to prevent diesel engine.Diesel engine in use, because oil sump pasta low (lack machine oil), machine oil are rotten, oil pump fault, machine oil pipeline blockage or leakage etc. can cause that all engine oil pressure is low, for the Z12V190 diesel engine, when engine oil pressure was lower than 350kpa, guiding valve moved down under the spring force effect, rotating shaft is being driven clockwise direction and is being rotated, shift fork is swung left, and stirs tooth bar and be moved to the left until the fuel cut-off position, and diesel engine just quits work automatically.When diesel engine used at the scene, the normal operation of low fuel pressure automatic stop device can't be judged, can only be confirmed quality by rule of thumb, has said nothing of the problem of verification.Stuck or the protection faults such as operating pressure is inaccurate of guiding valve often appear; then can't under the low situation of engine oil pressure, stop; diesel engine can be worked under the state of insufficient lubrication and be caused the parts depreciation aggravation; the motive position temperature is raise; bearing shell scaling loss etc.; cause diesel engine to be scrapped when serious, lead to major accident.
Summary of the invention
The purpose of this utility model is that a kind of diesel engine oil of design forces down the automatic stop device calibrator, it comprises pressure volume pot, air inlet-outlet pipe, pin type gate valve, oil pipe, pressure gauge, pressure volume pot are the container of high pressure sealing, and the pin type gate valve is installed on air inlet-outlet pipe, air inlet-outlet pipe and pressure volume pot UNICOM, machine oil is housed in pressure volume pot, and in the machine oil in the oil pipe bottom insertion pressure volume pot, the oil pipe outlet port is equipped with pressure gauge.The utility model utilizes the pressure release of suppressing of gas to determine that diesel engine oil forces down the minimum engine oil pressure of automatic stop device protection.The utility model has solved that diesel engine oil forces down long-term use of automatic stop device and an on-the-spot difficult problem that can't verification, has guaranteed the normal operation of diesel engine.
Description of drawings
Fig. 1 is a structure principle chart of the present utility model, 1 one pressure volume pots, 2 one air inlet-outlet pipes, 3 one pin type gate valves, 4 one pressure gauges, 5 one oil pipes, 6 one machine oil among the figure.
Embodiment
With reference to accompanying drawing 1, a kind of low fuel pressure automatic stop device calibrator, it comprises pressure volume pot 1, air inlet-outlet pipe 2, pin type gate valve 3, oil pipe 5, pressure gauge 4, pressure volume pot 1 is equipped with pin type gate valve 3 for the container of high pressure sealing on air inlet-outlet pipe 2, air inlet-outlet pipe 2 and pressure volume pot 1 UNICOM, machine oil 6 is housed in pressure volume pot, and in the machine oil 6 in the bottom insertion pressure volume pot 1 of oil pipe 5, oil pipe 5 outlet ports are equipped with pressure gauge 4, oil pipe 5 ends are equipped with a rapid pipe joint, and this rapid pipe joint is connected with the filler opening of low fuel pressure automatic stop device; Its working principle is to utilize pressurized air to pass through air inlet-outlet pipe 2 and pin type gate valve 3 to pressure volume pot 1 inner inflatable; machine oil 6 is compressed generation pressure and enters oil pipe 5; the elastic force that overcomes spring until the guiding valve of low fuel pressure automatic stop device moves up and drives rotating shaft and rotate in place; stop air feed then; close pin type gate valve 3 and keep a period of time; check for leaks; pull down compressed air inlet pipe and open pin type gate valve 3 a little; slowly pressure release; when pressure drops to a certain degree; when the oil pressure in the low fuel pressure automatic stop device reduces; when guiding valve is slightly larger than the power of oil pressure jack-up at the pressure of spring; sliding valve movement, rotating shaft rotate the action of drive shift fork and work, and the engine oil pressure of this moment is exactly the minimum engine oil pressure of its protection of automatic stop device.
Claims (2)
