Abstract
The utility model relates to a liquid-level switch, in particular to a non-contact submersible detachable liquid-level switch of a grease lubrication pump. The liquid-level switch comprises a protecting sleeve, an approach switch is arranged in the protecting sleeve, a bottom cover plate is arranged at the bottom of the protecting sleeve, and the protecting sleeve is mounted in a grease tank of a lubrication pump through an opening arranged on a support of the lubrication pump, and disposed under an induction plate of the lubrication pump. The approach switch is fixed through a guide sleeve and a spring. The liquid-level switch is mounted into the support of the lubrication pump integrally, and is simple in structure, convenient to maintain and long in service life. When the induction plate moves into an induction area of the approach switch, the approach switch can sends out induction signals, thereby realizing reliable detection. As the approach switch is fixed through the guide sleeve and the spring and has a function of vibration resistance, the liquid-level switch is particularly suitable for places with severe vibration.
Description
Technical field
The utility model relates to a kind of liquid-level switch, the detachable liquid-level switch of a kind of specifically grease formula lubricating pump noncontact immersion.
Background technology
The liquid-level switch that existing grease formula lubricating pump uses all is the low liquid-level switch of mechanical type, and mechanical type hangs down the liquid-level switch poor reliability, often causes grease to be lower than minimum liquid level and does not report to the police; The low liquid-level switch of mechanical type makes the friction pair dry friction, and moving component is fragile, and useful life is short, the maintenance trouble; In addition,, therefore, must take lubricating pump just apart and can carry out during maintenance, lose time because the low liquid-level switch of mechanical type is that integral body is encased in the oil tank.
Summary of the invention
Technical problem to be solved in the utility model is: at the shortcoming of above prior art existence, the detachable liquid-level switch of a kind of grease formula lubricating pump noncontact immersion is proposed, simple in structure, easy to maintenance, has shatter-proof function, the occasion that special use is bigger with vibrations.
The technical scheme that the utility model solves above technical problem is:
The detachable liquid-level switch of grease formula lubricating pump noncontact immersion; comprise a protective sleeve; be provided with one in the protective sleeve near switch; the protective sleeve bottom is provided with bottom plate; protective sleeve is encased in the lubricating pump oil tank by a perforate that is opened on the lubricating pump pump support, and is positioned at lubricating pump tablet below.
Like this, along with lubricating grease in the oil tank is consumed, its amount is fewer and feweri, and tablet is slowly motion downwards, will send induced signal in tablet arrives near the induction region of switch, realizes low liquid level warning function.
The technical scheme that the utility model further limits is:
The detachable liquid-level switch of aforesaid grease formula lubricating pump noncontact immersion is fixed by a guide pin bushing and spring near switch, and guide pin bushing is located near the switch below, and spring housing contacts on guide pin bushing and with bottom plate.
The detachable liquid-level switch of aforesaid grease formula lubricating pump noncontact immersion, protective sleeve are inverted n shape pipes.
The utility model has the advantages that: the utility model adopts whole by packing in the pump support, and is simple in structure, easy to maintenance, long service life; In the induction zone of tablet motion near switch, will send induced signal near switch, detect reliable; Owing to fix by guide pin bushing and spring, has shatter-proof function, the occasion that special use is bigger with vibrations near switch.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Embodiment one
Present embodiment is the detachable liquid-level switch of a kind of grease formula lubricating pump noncontact immersion; structure as shown in Figure 1; comprise a protective sleeve 6; protective sleeve 6 is inverted n shape pipes; be provided with one in the protective sleeve 6 near switch 7, protective sleeve 6 bottoms are provided with bottom plate 10, fix by a guide pin bushing 8 and spring 9 near switch 6; guide pin bushing 8 is located near switch 6 belows, and spring 9 is enclosed within on the guide pin bushing 8 and with bottom plate 10 and contacts.Protective sleeve 6 is encased in the lubricating pump oil tank 2 by a perforate that is opened on the lubricating pump pump support 5, and is positioned at lubricating pump tablet 3 belows, and tablet 3 can drive by oil sac 4 and move down along guide rod 1.
The assembling process of present embodiment is: will pack in the protection external member 6 near switch 7, and then, guide pin bushing 8 and spring 9 will be encased in the protective sleeve in 6, the perforate from pump support 5 at last is encased in the oil tank 2, tightens up bottom plate 10.
The course of work of present embodiment is: along with lubricating grease in the oil tank 2 is consumed, its amount is fewer and feweri, oil sac 4 can be with tablet 3 slowly to move along guide rod 1 downwards, will send induced signal in tablet 3 arrives near the induction region of switch 7, realizes low liquid level warning function.
The utility model is mainly used in to detect in the grease formula lubricating pump whether grease is lower than predefined low liquid level in the oil tank, sends alarm signal when grease in the oil tank is lower than the minimum liquid level of setting, and lubricating pump is quit work; Perhaps send signal and give, and allow it quit work by the control system of product.The non-immersion liquid-level switch that picks out of the present utility model adopts integral body by packing in the pump support, in the induction zone of tablet motion near switch, will send induced signal near switch, detects reliable.Owing to fix by guide pin bushing and spring, has shatter-proof function, the occasion that special use is bigger with vibrations near switch.
The utility model can also have other execution mode, and the technical scheme that equal replacement of all employings or equivalent transformation form all drops within the claimed scope of the utility model.
