Gravity flow type oil spout mouth detector

Abstract

The invention relates to an artesian ejector detector, which comprises: correcting connector, sealing ring, pressure meter, oil cup cover, oil cup, red copper pad, pressure meter connector, oil cup base, fixing nut, steel ball, sealing pad, valve base, plug muffle, piston, positioning screw, machine base, spring, baffle ring, piston support disc, lever, pin, base, screw, and handle, wherein the oil cup base is connected to the oil cup to be arranged at the upper end of oil inlet; the through hole of oil cup base is Phi 4-20mm. Since the oil cup is at the upper end of oil inlet, it uses artesian method, and it enlarges the oil inlet, the piston will contain oil always, to lubricant the piston and plug muffle, without dead clamp, to improve the reliability and 300% of producing efficiency. The invention can improve the detecting quality and the service life.

Description

1. Technical field: [0001] The self-flowing fuel injector detector relates to the technical field of fuel injector detection, in particular to the technical field of fuel injector detectors, and is applied to the detection of various fuel injectors. 2. Background technology: [0002] At present, the detectors used to detect fuel injectors in the domestic and foreign markets all adopt the adsorption type. In this structure, the oil storage tank is generally located on the lower side of the oil inlet hole, and the hydraulic pressure of the oil storage tank is connected through the oil pipe. The oil chamber sucks the hydraulic oil into the chamber in one direction in a state similar to a vacuum, and then squeezes out the oil nozzle in one direction with the piston force. After reaching a certain pressure, the fuel injection nozzle is tested. The qualified fuel injection nozzle is used in various For mechanical or internal combustion engines, due to the adsorption method, there ...

Problems solved by technology

[0002] At present, the detectors used to detect fuel injectors in the domestic and foreign markets all adopt the adsorption type. In this structure, the oil storage tank is generally located on the lower side of the oil inlet hole, and the hydraulic pressure of the oil storage tank is connected through the oil pipe. The oil chamber sucks the hydraulic oil into the chamber in one direction in a state similar to a vacuum, and then squeezes out the oil nozzle in one direction with the piston force. After reaching a certain pressure, the fuel injection nozzle is tested. The qualified fuel injection nozzle is used in various For mechanical or internal combustion engines, due to the adsorption method, there is a common problem that the oil circuit is easily blocked, and the hydraulic oil cannot be adsorbed. The hydraulic oil cannot reach the chamber in a vacuum state and work normally. Small, slow oil inlet speed, relatively low work efficiency, and because the hydraulic oil cannot enter the chamber, the piston is squeezed without oil, which may easily cause the piston to be strained. After a long time, the piston will be killed and the detector will be damaged.
