Abstract
A piston hydraulic pump is externally equipped with a hydraulic oil pump, a relief valve, an electromagnetic reversal valve, a travel switch, as well as a pressure gauge. Two linkage hydraulic oil pumps separately drive two hydraulic cylinder pistons to conduct telescopic movements, the outer ends of access one-way valve of the two hydraulic cylinders are separately connected in parallel with the access input tubes, along with the telescopic movements of the hydraulic cylinder pistons, the sizes in the cylinders are continuously changed, thereby uninterruptedly drawing the feed liquid from a feed one-way valve and extruding to a discharging one-way valve to complete the purpose of hydraulic pressure. In accordance with the requirements of media, the correspond sealing materials are allocated, the acidizing fluid, the alkali liquor, the water solution, the drill fluid, the cement slurry, as well as other thick fluid seeped with particles are the applicable media.
Description
The utility model relates to a kind ofly in the pump class can carry acid, alkali and be impregnated with the new pump class of the dense fluid of particle.
At present, the kind of oil hydraulic pump is a lot, but can be applicable to and carry acid, alkali, and the oil hydraulic pump that particularly can carry the dense fluid that is impregnated with particle is but seldom.
The purpose of this utility model provides a kind of piston type hydraulic pumps, and it can not only carry acid, alkali and be impregnated with the dense fluid of particle, and can finish high-pressure delivery.
The purpose of this utility model is to realize like this, on two oil hydraulic cylinders respectively pipeline be connected with feed check valve and discharging one-way valve, be connected on the feed pipe after two feed check valve outer end parallel connections, be connected on the discharge pipe after two discharging one-way valve outer end parallel connections, two hydraulic cylinder pistons are fixedlyed connected with two hydraulic cylinder piston rod screws respectively, two oil hydraulic cylinders are made concentric by pull bar respectively with two hydraulic jack shells and are located corresponding fixedlying connected, two hydraulic jack cavity of resorptions are communicated with by high-pressure oil pipe, two hydraulic jack epicoeles are connected in two outlets of solenoid directional control valve in the working oil path by two high-pressure oil pipes respectively, dispose oil pump in the working oil path, relief valve, the pressure gauge hydraulic element.Therein on the piston rod running orbit of a hydraulic jack, be provided with and stretch spacing and the position limit switch shrinkage limit position, transmit electrical signal by position limit switch and change the fuel feeding direction to solenoid directional control valve, make the piston of hydraulic jack not reciprocating not left alone without helply, on the piston of another hydraulic jack, be provided with a pair of one-way valve group, being opposite direction by two normally closed one-way valves assemblies, unidirectional valve rod all exposes valve seat, when this piston runs to limit position, wherein one-way valve valve rod in the one-way valve group is subjected to really to bump and opens, and this piston is communicated with both sides up and down, and hydraulic oil circulates in combination brake switch and proporting, and finish the self-regulating purpose of oil-filled amount in the cavity of resorption of two hydraulic jacks, and guaranteeing that two hydraulic jacks all stably do this and stretch that and contract in effective travel, that stretches this work of contracting, and drives oil hydraulic cylinder and does stably to inhale to press work.
Owing to adopt such scheme, can control the pressure of feed liquid output easily and intuitively, to connect true mechanism structure simple, easy to use with feed liquid.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is vertical section structure figure of the present utility model.
Fig. 2 is the combination check valve enlarged view among Fig. 1.
