Abstract
The utility model relates to a filter with a buzzer, which is arranged in a hydraulic system. The hydraulic system often has faults because the filter can not be replaced or cleaned in time at real work. The utility model provides the filter with the buzzer for sending the sound in time when impurities in a filter core are increased so as to promote work stuff to replace or clean the filter core. The filter consists of a top cover, a case, a bottom cover, the filter core, a support plate, a piston, a spring, the buzzer, a normally open contact, a filter core cavity, an outer cavity, a bottom cavity, an oil inlet and an oil outlet. The utility model is characterized in that the lower end of a piston rod is in contact with the normally open contact. When the impurities in the filter core are increased, the pressure of hydraulic oil in the filter core cavity is increased, the increased pressure makes the piston of the bottom surface of the filter core cavity move downwards, the normally open contact is closed through the piston rod, and a power supply of the buzzer is switched on to give the sound.
Description
Technical field:
The utility model relates to the filter of band buzzer in a kind of Hydraulic Power Transmission System.
Background technology:
Filter all is installed in the Hydraulic Power Transmission System, is used to guarantee cleaning and system's operate as normal of hydraulic oil, but in actual motion, often the cycle is changed, cleans filter core in accordance with regulations, and impurity increases in the hydraulic system to making, and causes fault to take place frequently.
Summary of the invention:
The utility model provides a kind of filter with buzzer.It is made up of top cover, housing, bottom, filter core, supporting plate, piston, piston rod, spring, buzzer, normally opened contact, filter core chamber, exocoel, chamber, the end, oil-in, oil-out, it is characterized in that, piston-rod lower end contacts with normally opened contact.The hydraulic oil of certain pressure enters into the filter core chamber from the filter oil-in.Behind filter element filtering, enter exocoel, again by oil-out input hydraulic pressure system.When impurity in the filter core and dirt increased, the filter core intraluminal fluid pressed the pressure of oil to raise.This elevated pressure makes the piston end surface in the supporting plate of bottom surface, filter core chamber stressed.After piston was stressed, against the force of the spring moved downward, and made the normally opened contact closure that contacts with piston-rod lower end, connected to be installed at the bottom of the filter electric power loop of buzzer in the chamber, and buzzer then sends sound, and the prompting staff in time changes or the cleaning filter core.After filter core was changed and cleaned, the filter core intraluminal fluid pressed oil pressure to recover normal, and piston sets back under spring force.
Because filter core is in time changed, cleaned to the cycle in accordance with regulations, the interior hydraulic oil of hydraulic system can often keep clean, take place thereby reduce fault.
Description of drawings:
Accompanying drawing is the utility model cross-sectional view.
The specific embodiment:
As shown in drawings, supporting plate (5) is installed in the housing (13) with interference fits.Piston (9) is contained in the piston cylinder (16) at supporting plate (5) middle part.Piston (9) and piston rod (17) are made one, and spring (11) is enclosed within on the piston rod (17), and guide cover (15) is connected with piston cylinder (16).Filter core (3) upper end is connected movingly with top cover (2).The lower end is pressed on the supporting plate (5), and top cover (2) is connected with housing (13).There is oil-in (1) upper end, filter core chamber (14), and there is piston (9) bottom surface, lower end, is exocoel (4) between filter core (3) outside and housing (13) inwall, and (12) are oil-out.Buzzer (6), normally opened contact (10) are contained in the following chamber, the end (19) of supporting plate (5).Piston rod (17) lower end contacts with normally opened contact (10).Bottom (18) is connected with housing (13) lower end.Behind power line (7) the serial connection buzzer (6), be connected with normally opened contact (10).Power line (8) is connected with normally opened contact (10).
