Abstract
An oil pumping prevention safe oil pump comprises a pump body (1), a pump cover (2) and a safe valve (3), wherein the safe valve (3) comprises a safe-valve plunger (31), a safe-valve spring (32) and a safe-valve screw plug (33), the safe-valve plunger (31) and the safe-valve spring (32) are mounted in a safe-valve hole formed by the pump cover (2); and an adjustable valve (4) comprises an adjustable-valve plunger (41), an adjustable-valve spring (42) and an adjustable-valve screw plug (43), the adjustable-valve plunger (41) and the adjustable-valve spring (42) are mounted in an adjustable-valve hole through the adjustable-valve screw plug (43), and an annular groove (411) is formed at the middle part of the adjustable-valve plunger (41). The safe oil pump can avoid the breakage of a pipeline and a filter cleaner caused by excessive oil pressure of a main oil duct of an engine, and also can prevent oil from entering into a combustion chamber by controlling and stabilizing the oil pressure of a circular oil line of the main oil duct of the engine to.
Description
Technical field
The utility model relates to the safe oil pump of the anti-channeling oil of a kind of oil pump of engine lubrication system, particularly a kind of energy-conserving and environment-protective.
Background technique
Have now and the supporting band safety valve oil pump of motor, only be provided with a safety valve on it, safety pressure in order to the controller oil pump, though it can prevent breaking of oil pump and oil duct and filter, but it also has the following disadvantages: in cold, during extraordinary circumstances such as driving, pressure in the engine oil pipeline of vehicle motor will raise, this machine band safety valve oil pump can not guarantee the pressure stability of whole engine oil passage system, when the oil pressure in the main oil gallery circulating oil path is higher, can make machine oil scurry into combustion chambers burn, so both waste machine oil, polluted environment again.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and safe oil pump that a kind of anti-channeling oil is provided, it can avoid engine motor oil main oil gallery oil pressure too high and cause breaking of pipeline and filter cleaner, it can also be controlled and the engine oil pressure of stable engine motor oil main oil gallery circulating oil path is scurried into burning and stopped up to prevent machine oil, and can cut down the consumption of energy, reduce power loss, reduces Oil Consumption, reduces the pollution to environment.
The technical solution of the utility model is: a kind of safe oil pump of anti-channeling oil, and it comprises the pump housing, pump cover, safety valve and modulating valve; Safety valve comprises safety valve plunger, safety valve spring and safety valve plug screw, and safety valve plunger and safety valve spring are installed in the safe valve opening that pump cover leaves by the safety valve plug screw; Modulating valve is located at out between oil pocket and the oil suction chamber, modulating valve can by with cavity that the motor main oil gallery is communicated with in pressure oil control break-make.
The further technological scheme of the utility model is: described modulating valve comprises modulating valve plunger, modulating valve spring and modulating valve plug screw, modulating valve plunger and modulating valve spring are installed in the adjusting valve opening that the pump housing leaves by the modulating valve plug screw, modulating valve plunger middle part is provided with circular groove, and the circular groove of its modulating valve plunger can be linked up out oil pocket and oil suction chamber when modulating valve was opened.
The utility model compared with prior art has following characteristics: the utility model is owing to adopt safety valve and the dual valve arrangement of modulating valve, can be on the basis that guarantees oil pump and pipeline and filter safety, improved the stability of oil pressure in the main oil gallery circulating oil path, prevent the motor accident and produce the buffer protection function that oil pressure is crossed HI high impact, simultaneously, can also reduce machine oil and scurry into combustion chambers burn, reduce environmental pollution because of pressure is high; When motor main oil gallery engine oil pressure is too high, modulating valve will be linked up out oil pocket and oil suction chamber, oil pump excess pressure oil is flowed to oil suction chamber, thereby reduce oil pump oil outlet flow and pressure, and then the engine oil pressure of stable main oil gallery, but also can reduce the power consumpiton of oil pump, improve the working life of Security, reliability and the prolongation motor of haveing suffered lubrication system.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Embodiment is shown in Fig. 1-2: a kind of safe oil pump of anti-channeling oil, and it comprises the pump housing 1, pump cover 2, safety valve 3 and modulating valve 4; Safety valve 3 comprises safety valve plunger 31, safety valve spring 32 and safety valve plug screw 33, safety valve plunger 31 and safety valve spring 32 are installed in the safe valve opening that pump cover 2 left by safety valve plug screw 33, when the oil pressure that goes out oil pocket 51 is elevated to certain pressure, when safety valve 3 is opened, go out oil pocket 51 in part machine oil just let out in the cavity 52 that is connected with oil sump, thereby the overpressure that can prevent out oil pocket 51 causes breaking of oil pump and main oil gallery and filter; Modulating valve 4 comprises modulating valve plunger 41, modulating valve spring 42 and modulating valve plug screw 43, modulating valve plunger 41 and modulating valve spring 42 are installed in the adjusting valve opening that the pump housing 1 left by modulating valve plug screw 43, modulating valve plunger 41 middle parts are provided with circular groove 411, be communicated with the motor main oil gallery with the cavity 54 that the end face 412 of modulating valve plunger 41 adjoins, promotion modulating valve plunger 41 moves its circular groove 411 of back and can link up out oil pocket 51 and oil suction chamber 53 under the effect of the certain pressure oil of the end face 412 of modulating valve plunger 41 in cavity 54.
The working principle of modulating valve 4: when motor main oil gallery engine oil pressure is too high, pressure oil in the cavity 54 that is communicated with the motor main oil gallery will act on the end face 412 of modulating valve 4, promoting modulating valve plunger 41 moves to modulating valve plug screw 43 directions, at this moment the circular groove 411 at modulating valve plunger 41 middle parts can be linked up out oil pocket 51 and oil suction chamber 53, the pressure oil that goes out oil pocket 51 excess pressure of oil pump will flow to oil suction chamber 53, to reduce flow and the pressure that oil pump goes out oil pocket 51 oil outlet machine oil, stablize the engine oil pressure of motor main oil gallery, thereby can prevent to make machine oil scurry into the firing chamber when higher because of the oil pressure in the main oil gallery circulating oil path; The engine oil pressure that modulating valve 4 has been stablized main oil gallery can also reduce the power consumpiton of oil pump, the working life of improving Security, reliability and the prolongation motor of whole lubricating system.
The utility model is not limited to above-mentioned concrete structure, so long as go out between oil pocket 51 and the oil suction chamber 53 modulating valve 4 of design and by with cavity 54 that the motor main oil gallery is communicated with in pressure oil come the oil pump of regulating and controlling valve 4 unlatchings just to drop within the protection domain of the present utility model.
