Abstract
The utility model discloses a measuring and testing gun for an injection pump which is an improved measuring and testing device of the injection pump of a diesel engine. The external form of the measuring and testing gun can be in the gun shape, and can be held and operated by one hand. The injection pump dispenses with being disassembled from the diesel engine while in use. A pressure meter is arranged on the casing of the measuring and testing gun, and the opening pressure of the injection pump can be measured. The measuring and testing gun for the injection pump has the advantages of light weight, small size and convenient portability.
Description
The utility model relates to a kind of improved diesel injector detection device.
The oil sprayer detection device that generally adopts both at home and abroad is fixed on the worktable and uses at present.The volume and weight of this oil spout detection device is big, be not suitable for being carried in that diesel engine work is on-the-spot by the maintainer and use.The C251 type oil sprayer detector that nineteen eighty-two Czechoslovakia's motor Ba Er (Motorpal) company produces has adopted both hands to pull the pincerlike structure of handle, and length is 480mm, needs the both hands hand-held during use.
The purpose of this utility model provides a kind of improved diesel injector detection device.It is characterized in that: profile is pistol-shaped, can the single-hand held operation.
Technological points of the present utility model is: oil sprayer detects in the rifle housing plunger coupled parts and delivery valve matching parts is housed.When the hand-held oil sprayer detection of operator rifle, when pulling handle with finger, handle promotes plunger pump oil through roller.High pressure fuel enters diesel injector through outlet valve and high-pressure oil pipe.The pump end pressure can reach more than the 30MPa.The housing outside of oil sprayer detection rifle is equipped with pressure gauge also is housed on oil conservator, the housing, can measure the cracking pressure of oil sprayer.When detection and adjustment injection pressure of injector, will not remove from diesel engine by oil sprayer.Loam cake is housed, so that add fuel oil on the oil conservator.On cover vent valve be housed, unscrew vent valve the gas pressure in the oil conservator is equated with atmospheric pressure.Oil conservator and loam cake can when making with transparent plastic, be convenient to observe the trapped fuel amount in the oil conservator with metal or transparent plastic manufacturing, can in time add during oil starvation.
The utility model compared with prior art; the advantage that is had is: in light weight, volume is little, be easy to carry; easy to use; can operate by single-hand held; when detecting and adjust injection pressure of injector; can not will oil sprayer remove from diesel engine, improved work efficiency, reduced time of shutting down maintenance.
Accompanying drawing is the sectional arrangement drawing of a kind of concrete structure of the present utility model.
Structure and working condition below in conjunction with description of drawings a kind of embodiment of the present utility model.
Oil sprayer detects the housing (1) that rifle comprises that an aluminum alloy is made.Plunger coupled parts (3) and delivery valve matching parts (8) are housed in the housing (1).When the hand-held oil sprayer of operation detects rifle, and when pulling handle (2), be contained in roller (9) the promotion plunger pump oil on the handle with finger.High pressure fuel enters diesel injector through outlet valve (8) and high-pressure oil pipe (10).The pump oil pressure can reach more than the 30MPa.Pump oil rear spring (11) makes plunger return initial position.At this moment fuel oil in oil inlet hole enters plunger coupled parts (3), is equipped with loam cake (6) from oil conservator (4) on the oil conservator (4), opens loam cake oil conservator just capable of washing inside and adds fuel oil.Oil conservator (4) and loam cake (6) are convenient to observe the trapped fuel amount in the oil conservator by the transparent plastic manufacturing, in time add during oil starvation.Vent valve (7) is housed on the loam cake (6), unscrews behind the vent valve the just inner and atmosphere of oil conservator and communicate, can make gas pressure and atmospheric pressure in the oil conservator equal.Pressure gauge (5) also is housed on the housing (1), can measures the cracking pressure of oil sprayer.The maximum boundary dimension that oil sprayer detects rifle is not more than 350mm.
Claims (6)
1, a kind of oil spout detection device that comprises housing [1], handle [2], plunger coupled parts [3], it is characterized in that: profile is pistol-shaped, can the single-hand held operation.
2, device according to claim 1 is characterized in that in housing (1) outside oil conservator (4) being housed.
3, device according to claim 1 is characterized in that being equipped with on the housing (1) pressure gauge (5).
4, device according to claim 2 is characterized in that being equipped with on the oil conservator (4) loam cake (6).
5, device according to claim 4 is characterized in that being equipped with on the loam cake (6) vent valve (7).
6, device according to claim 4 is characterized in that oil conservator (4) and loam cake (6) are by the transparent plastic manufacturing.
