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
One, technical field:
Gravity flow type oil spout mouth detector of the present invention, what relate to is fuel injection nozzle detection technique field, particularly the technical field of oil spout mouth detector is applied to the detection of various fuel injection nozzles.
Two, background technology:
At present, be used for the detecting device that detects fuel injection nozzle on the domestic and international market, all adopt absorption type, this frame mode, generally speaking, storage tank is located at the downside of oil supply hole, is being similar under the vacuum state the unidirectional intake chamber of hydraulic oil with chamber by the hydraulic oil of oil pipe with storage tank, extrude with piston force is unidirectional again, after reaching certain pressure fuel injection nozzle is detected, detect qualified fuel injection nozzle and be applied to all kinds of machineries or internal combustion engine, owing to adopt the method for absorption type, it is blocked easily that ubiquity oil circuit, can't adsorb hydraulic oil, hydraulic oil can't arrive the chamber under the similar vacuum state, carries out operate as normal, have again, because absorption affinity is little, oil-feed speed is slow, and work efficiency is relatively low, again because hydraulic oil can't enter chamber, piston does not have the oil extruding, causes piston to be pulled easily, and the time one is of a specified duration, piston is killed, and damages detecting device.
Three, summary of the invention:
The objective of the invention is to overcome above-mentioned defective, design a kind of lubricating cup and be located at the oil supply hole upper end, hydraulic oil enters chamber in the mode of gravity flow, again by the unidirectional gravity flow type oil spout mouth detector of extruding of piston force.Its technology is achieved in that the structure that comprises checking joint, O-ring seal, tensimeter, oil cup cap, lubricating cup, copper washer, pressure tapping, oil cup seat, locknut, steel ball, packing washer, valve seat, plunger bushing, piston, dog screw, support, spring, back-up ring, piston pallet, lever, pin, base, screw, handle, it is characterized in that: the lubricating cup that oil cup seat connects is located at the oil supply hole upper end, the oil cup seat through hole is Φ 4-20mm, square or rectangular base is provided with the screw of fixed handle, and oil cup cap and lubricating cup are by being threaded.The positive effect of implementing after this technology is: at first overcome above-mentioned defective, because lubricating cup is located at the oil supply hole upper end and adopts the gravity flow oil-feed, and enlarged oil supply hole, can not stop up oil circuit, the phenomenon of oil can not appear not having like this in piston, thereby lubricated piston, plunger bushing and not killed, guaranteed the reliability of using, shorten running time and dynamics, improved production efficiency 300%, prolonged the serviceable life of detecting device, improved the detection quality of fuel injection nozzle, thereby improved the complete machine quality of using the machinery, particularly diesel engine of fuel injection nozzle indirectly, Promoting International Competition Ability.
