Description
Technical field
The utility model relates to a kind of appurtenances of reciprocating hydraulic diaphragm pump, especially reciprocating hydraulic diaphragm pump differential pressure type oil mass automatic controller.
Background technique
Big-and-middle-sized reciprocating hydraulic diaphragm pump is big because of feed flow, and reciprocal time is generally slower, makes piston displacement bigger.Be volume and the diaphragm diameter that reduces fluid cylinder, all be designed to large deflection " dish " diaphragm of rubber structure.The distortion of the elastomer diaphragm that diaphragm pump is used is relevant with the difference force on acting on diaphragm: the pressure reduction that diaphragm pump hydraulic pressure cavity and media cavity exist is incomplete same in running, when diaphragm does not contact forward and backward chamber confinement plate, the pressure of both sides chamber is basic (balance) that equates in theory, but in fact as long as barrier film is also in motion, just certainly exist active force (also claiming difference force) on the diaphragm, this power comprises the power that makes motion of membrane and the power of diaphragm deflection.And diaphragm is different at the deformation force of the neutral position and the position of keeping to the side, and amount of deformation (relevant with diaphragm diameter and thickness) is big more, and deformation force (relevant with barrier film hardness or tensile strength) is also big more; When the fed sheet of a media temperature was higher than normal temperature, temperature was high more, and the deformation force of same amount of deformation is more little; The big more suffered external force of fluctuating acceleration (relevant with reciprocal time and running length) (motion difference force) of diaphragm motion is big more.Therefore have only diaphragm to mediate and when not moving the pressure of both sides chamber just definitely equate (no difference force), diaphragm just is in state of equilibrium.
Because oil level is higher, under the oil pressure effect, elastomer diaphragm distortion is bigger when hydraulic pressure cavity is refueled, and is prone to refuel excessive phenomenon, causes pump to be in operation the hydraulic pressure cavity oil pressure to occur too high, causes the early damage of diaphragm; In the special process flow process, the fed sheet of a media temperature is higher, and more yielding tenesmus after the film diaphragm is heated produces compressive strain or wearing and tearing with forward and backward casing wall applying back, also can cause the early damage of barrier film; The hydraulic oil of chamber can be located the leakage of hydraulic oil or the hydraulic oil quantity not sufficient that discharging excessively produces because of piston, bleed valve, safety valve etc. in running, cause noise, the excessive and underfed of vibration, needs in good time repairing.Therefore the control of the normal oil mass of hydraulic diaphragm pump hydraulic pressure cavity is to guarantee that pump normally moves, improves one of key measure of membrane life.
And in the prior art, fail finely to utilize that the pressure reduction of hydraulic pressure cavity and media cavity changes in good time repairing or oil extraction in the suction process, realize effective control of hydraulic pressure cavity oil mass, to guarantee the normal operation of pump.
Summary of the invention
The pressure reduction of hydraulic pressure cavity and media cavity does not change the device that comes repairing or oil extraction, the deficiency that can not effectively control the hydraulic pressure cavity oil mass to the utility model in the suction process at utilizing in the prior art, and a kind of reciprocating hydraulic diaphragm pump differential pressure type oil mass automatic controller is provided.
The technical solution of the utility model: reciprocating hydraulic diaphragm pump differential pressure type oil mass automatic controller, comprise the fluid cylinder head, the fluid cylinder head is provided with media cavity and hydraulic pressure cavity, it is characterized in that: media cavity pressure head is set on media cavity, hydraulic pressure cavity pressure head, fluid infusion mouth and oil drain out are set on hydraulic pressure cavity; Media cavity pressure head and hydraulic pressure cavity pressure head are electrically connected with differential pressure transmitter, and detected pressure signal is input in the differential pressure transmitter, and differential pressure transmitter is electrically connected with the processing regulator; The output terminal of handling regulator is electrically connected with Fill valve, the draining valve on the oil extraction pipeline on the repairing pipeline respectively; One end of repairing pipeline is connected with oil storage tank, is connected with the fluid infusion mouth through one-way valve; The oil extraction pipeline is connected with oil drain out, on the oil extraction pipeline one-way valve is set;
Further be characterised in that: on repairing pipeline and/or oil extraction pipeline, manual modulation valve is set.
Reciprocating hydraulic diaphragm pump differential pressure type oil mass automatic controller of the present utility model has following characteristics:
1, can utilize the pressure reduction of hydraulic pressure cavity and media cavity in the suction process to change fast, repairing or oil extraction in hydraulic pressure cavity in time, avoid refueling excessive, the too high caused diaphragm early damage phenomenon of hydraulic pressure cavity oil pressure; Avoid the hydraulic oil quantity not sufficient, cause the phenomenon of noise, the excessive and underfed of vibration, make diaphragm pump operate steadily, improve membrane life.
2, simple in structure, easy to operate.
