Background technique
ZB-1 type lubricant pump test-bed is in order to detect the performance parameter of engine lubrication system component, this test stand can complete the adjustment of the pressure of motor oil Pump For Machine on seven kinds of model tractors such as Dongfanghong-75, car pusher-55 and automobile, flow measurement and related valves, the adjustment of the machine oil passing capacity of oil filter, sealing and related valves, the verification of fuel level indicator.
In recent years, along with the development of internal-combustion engine technology, the application of high-performance, high power engine is more and more extensive, also higher to the requirement of engine lubrication system; Dynamical element oil pump as lubrication system not only wants reliable operation, and it is also increasing to pressure, traffic requirement, former test stand exposes following problem: one be test oil pump peak rate of flow be 55l min, can not meet the test of oil pump performance, limit the using scope of test stand; Two is adopt method of using a sand filter for marking the hours to coordinate to be communicated with glass tube measuring flow, and detect by an unaided eye, error is comparatively large, in addition, will control hourglass and open and close valve in oil pump capacity test process simultaneously, and operating process is complicated; Three is each test process, and all the machine oil in lower fuel tank will be extracted in top tank, fluid is not recycle oil, and for ensureing that test is carried out smoothly, lower fuel tank just needs to add a large amount of fluid, causes unnecessary waste.
Summary of the invention
The purpose of this utility model there is provided a kind of lubricant pump test-bed hydraulic pressure installation, solve that existing ZB-1 type lubricant pump test-bed can not meet the test of oil pump performance, measuring flow detects by an unaided eye, error is comparatively large, operating process is complicated and the problem of test process waste oil.
In order to achieve the above object, the utility model by the following technical solutions, a kind of lubricant pump test-bed hydraulic pressure installation, comprise fuel tank, oil pump, throttle valve, connect dish, modulating valve, two-bit triplet solenoid valve, pressure gauge, flowmeter, pressure gauge, safety valve, tachometer and motor, wherein, a two-bit triplet solenoid directional control valve is connected in modulating valve outlet port, the an outlet directly logical fuel tank of two-bit triplet solenoid directional control valve, another outlet connects flowmeter, flowmeter the other end connected tank, connects the indirect pressure gauge of dish and modulating valve.
A kind of lubricant pump test-bed hydraulic pressure installation, wherein not measurement of discharge time, two-bit triplet solenoid valve is when deenergization, and fluid directly flows back to fuel tank through two-bit triplet solenoid valve; When needing measurement of discharge, connect two-bit triplet power of electromagnetic valve, its electromagnet YA promotes the commutation of two-bit triplet valve core of the electromagnetic valve, and fluid is by flowmeter oil sump tank again after two-bit triplet solenoid valve, and flow then can read from flowmeter.
The beneficial effects of the utility model are: by improving, only need control two-bit triplet solenoid valve power on/off, button press gets final product measurement of discharge, make control simple, reliable; Meanwhile, flow can directly read from flowmeter, and measuring accuracy reaches national C level (± 2 .5 %) standard; Eliminate the hourglass on former test stand, top tank, glass tube and open and close valve, make system simplification; In addition, system makes full use of circulation fluid, makes test closer to real work situation; Test stand after improvement can not only complete the test to old model tractor, vehicle lubricating system element function, but also can complete the big-power tractor engine lubrication system element function test that the combine-harvesters such as Dongfanghong-1002 high and medium power tractor such as grade and E512, E514 and the Production and Construction Corps of Xinjiang introduced in recent years.
