Abstract
The utility model relates to a novel diaphragm pump oil cylinder, in particular to a structural improvement of the diaphragm pump oil cylinder. The diaphragm pump oil cylinder is low in cost and simple in structure. The diaphragm pump oil cylinder comprises an oil cylinder body, a guide rod is arranged in the oil cylinder, and a magnet ring is arranged on the guide rod. The diaphragm pump oil cylinder is characterized in that the oil cylinder body is provided with a signal generating device corresponding to the magnet ring, the signal generating device comprises a shell arranged on the oil cylinder body, and two magnetic sensors are sequentially arranged in the shell in the direction of the guide rod.
Description
Technical field
The utility model relates to a kind of improvement of diaphragm pump cylinder structure.
Background technique
Oil cylinder is positioned at three cylinder single-acting membrane pump fluid ends, mainly parts such as cavity, guide rod supports cover, signal occurrence device and pistons, is consisted of.Signal occurrence device in oil cylinder determines whether to carry out repairing or oil extraction by detecting barrier film guide rod position.This device be determine oil cylinder general structure and membrane pump fluid end can safety, the key factor of stable operation, the traditional oils cylinder structure adopts two signal occurrence device (being repairing telltale, oil extraction telltale), this kind of structure oil cylinder signals collecting amount is more, is unfavorable for that the stable operation of equipment and manufacturing cost are higher.
Summary of the invention
The utility model is exactly for the problems referred to above, and diaphragm pump oil cylinder a kind of with low cost, simple in structure is provided.
For reaching above-mentioned purpose of the present utility model, the utility model adopts following technological scheme, the utility model comprises oil cylinder, be provided with guide rod in oil cylinder, be provided with magnet ring on guide rod, it is characterized in that: be provided with signal occurrence device corresponding to magnet ring on oil cylinder, described signal occurrence device comprises the housing be arranged on oil cylinder, in housing, along the guide rod direction, sets gradually two magnetic-type sensors.
The beneficial effects of the utility model: 1, simplify cylinder structure, be easy to processing.
2, the utility model has saved a signal occurrence device, and in the mono signal generating means, two magnetic-type sensors are controlled benefit, oil extraction, have shortened oil cylinder length, thereby has reduced the manufacturing cost of oil cylinder.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model signal occurrence device.
In accompanying drawing 1 be guide rod, 2 for oil cylinder, 3 for magnet ring, 4 for signal occurrence device, 5 at the bottom of box, 6 for the magnetic-type sensor, 7 for housing, 8 for gland, 9 be helmet.
Embodiment
The utility model comprises oil cylinder 2, be provided with guide rod 1 in oil cylinder 2, be provided with magnet ring 3 on guide rod 1, it is characterized in that: on oil cylinder 2, corresponding to magnet ring 3, be provided with signal occurrence device 4, described signal occurrence device 4 comprises the housing 7 be arranged on oil cylinder 2, and housing 7 is interior sets gradually two magnetic-type sensors 6 along guide rod 1 direction.
The housing 7 of described signal occurrence device 4 comprises at the bottom of box 5 and gland 8, and described two magnetic-type sensors 6 are arranged at the bottom of box in 5.
Described gland 8 tops are provided with helmet 9.
Described magnetic-type sensor 6 can be purchased by market.
Below in conjunction with accompanying drawing, one-off process of the present invention is described: when the guide rod 1 in oil cylinder 2 moves, magnet ring 3 on guide rod 1 moves thereupon, while along with magnet ring 3, moving closer to first magnetic-type sensor 6, signal occurrence device 4 sends testing signal based on first magnetic-type sensor 6, do not carry out repairing, oil extraction action, only detected; Along with magnet ring 3 continues motion, while moving closer to second magnetic-type sensor 6, when second magnetic-type sensor 6 receives the magnetic line of force that magnet ring 3 sends and arrive the magnetism intensity of a certain setting, signal occurrence device 4 sends the repairing signal based on second magnetic-type sensor 6, carries out repairing.
If, when first magnetic-type sensor 6 can't accept testing signal, carry out the oil extraction action.
Completed the work of two signal occurrence device 4 by a signal occurrence device 4, simplify the structure, shortened oil cylinder 2 sizes, reduced cost of production.
Be understandable that, above about specific descriptions of the present utility model, only for being described, the utility model not is limited to the described technological scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as meet, all within protection domain of the present utility model.
