Abstract
The utility model relates to a double-cylinder hydraulic diaphragm pump. The double-cylinder hydraulic diaphragm pump can adapt to different occasions, the press and filtration, the slurry transmission, and the spray and drying of various slurry materials, etc. The slurry adopts that hydraulic oil directly agitates one diaphragm and a linking rod is used to pull the other diaphragm to generate the purpose of sucking and pressing the slurry. An inner technology and an outer technology are mutually fed back by the diaphragms and a hydraulic system, a flow rate and pressure are automatically adjusted, and thereby, energy saving, efficiency improving, structure simplifying are achieved. The double-cylinder hydraulic diaphragm pump is the optimum equipment which is provided for transporting various slurry materials by ambient pressure and flow rate change.
Description
The utility model is a kind of by the hydraulic system fuel feeding, directly agitates the mashing pump of barrier film.
Traditional diaphragm pump, generally be machinery, the quantitative slurry supply pump of crank-type, with the pressure filter auxiliary work time, because pressure-filtering process is to pumping pressure, the particularity of traffic demand is (when being exactly the turn on pump press filtration, resistance is little, filtration yield is big, along with the part slurry dewatering, the press filtration resistance increases gradually, filtration yield reduces), a large amount of idle works has been made in the particularity requirement in the time of can not adapting to this press filtration, recently hydraulic diaphragm pump has been done a large amount of development work for this reason, the TCB140 high low pressure diaphragm pump that Jingdezhen Ceramics Machinery Factory produces at present still can not address this problem, and pump structure is complicated.
The utility model then is to solve above-mentioned specific (special) requirements problem, and changes pump structure, selects pressure limiting power variable vane pump for use, as energy conversion, with the change in resistance of press filtration, the permanent power output of hydraulic oil, thereby can reasonablely satisfy the press filtration requirement, reach the energy saving purpose, and simplified structure.
Structural principle of the present utility model is stated with reference to Fig. 1.
Fig. 1 is a configuration state sectional view of the present utility model.
With reference to Fig. 1 structural principle of the present utility model is by two barrier films ［ 7 ］, (7 ') in the twin-tub that is in pump respectively, this two barrier film ［ 7 ］, between (7 ') be with a connecting rod 6) connect; Supply pressure oil (at the beginning by the quantitative blade hydraulic pump fuel feeding of big flow by pressure limiting power variable vane pump in the hydraulic system and the exchange in parallel of quantitative blade hydraulic pump, to the certain pressure pressure limiting variable vane pump fuel feeding that just automaticallyes switch, this pressure limiting power variable vane pump can adapt to the delivery pressure feedback and adjust flow automatically, remain the output of permanent power), enter the commutation main valve (3 ］ and Displacement Feedback selector valve (5) be assigned in pump two cylinders and directly agitate barrier film; When pressure oil enters a cylinder and agitates barrier film (7), then the barrier film in another cylinder 7 ') inhale slurry by connecting rod (6) pulling, simultaneously the hydraulic oil pressure oil sump tank, when barrier film (7 ' ］ when the certain position, touch Displacement Feedback selector valve (5) and make pressure oil commutation earlier, the direction of impelling commutation main valve (3) to change pressure oil flows to another cylinder and agitates barrier film (7 '); Make barrier film (7 ') mud jacking, back and forth agitate barrier film (7), (7 ') formation compression and vacuum to drive one-way valve thus and finish mud jacking, inhale slurry.When changing, extraneous technology, pressure, flow just can reach energy-conservation purpose by automatic adjustment of pressure limiting power variable vane pump that barrier film (7), (7 ') feed back in the hydraulic system.For obtaining reliable and secure operation, the main valve (3) that prevents to commutate is malfunctioning breaks barrier film with pressure oil, and the utility model is equipped with feeler lever protective gear (4) on the commutation main valve.
The utility model is a kind of double-cylinder hydraulic variable diaphragm pump, can be adapted to the press filtration of different occasions, various slurries, defeated slurry and spray drying etc., this pump adopts hydraulic oil directly to agitate a barrier film to spur another barrier film with connecting rod and produces suction, mud jacking purpose, thereby and feed back mutually by barrier film and hydraulic system inside and outside technology, flow, pressure are regulated automatically reach energy-conservation and are raised the efficiency, simplified structure, be the best equipment that ambient pressure, changes in flow rate carry various slurries to be equipped with.
