Description
Technical field:
The utility model relates to oil pressure actuated and carries slurry pressurized equipment field, relates in particular to oil pressure ceramic plunger slurry pump pressure compensator.
Background technique:
At present, the YB plunger pump is divided into quantitatively and two kinds of forms of variable, metering pump is driven by the quantitative oil pump fuel feeding, variable displacement pump is driven by two quantitative oil pump classification fuel feeding, no matter but which kind of adopts for oil form, all be difficult to adapt to the variation of bearing power, now take pressure filter as load as example, pressure filter is a kind of dewatering by extruding equipment, the general YB plunger pump of using is for the slurry pressurization, and slurry flow is larger when initial, and the YB plunger pump is in normal working, but because the saturated accumulation with expecting matter of the volume of pressure filter, the delivery side of pump increased pressure, required flow also reduces gradually simultaneously, and the input power of YB plunger pump does not change, so just cause very large power loss, and most of energy that loses all will be discharged by the fluid valve from hydraulic system, thereby can cause system's heating, and oil temperature raises, not only can affect the YB plunger pump life-span, also can quit work when serious.
The model utility content:
The purpose of this utility model provides oil pressure ceramic plunger slurry pump pressure compensator, and it can make YB delivery side of pump power equal the output power of oil pump, has reduced significantly energy consumption, has improved efficient, has prolonged the working life of YB plunger pump.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it is comprised of oil pump 1, variable piston 2, PC valve 3, remote pressure regulating valve 4, one-way valve 5, hydraulicchange-over valve 6, rotary valve 7, oil cylinder 8, ceramic plunger 9, the mud pump housing 10, fluid valve 11; Oil pump 1 is connected with fluid valve with variable piston 2, PC valve 3, remote pressure regulating valve 4, one-way valve 5 respectively and is connected, variable piston 2 is connected with PC valve 3, PC valve 3 is connected with remote pressure regulating valve 4, one-way valve 5 is connected with the oil inlet end that rotary valve 7 is connected with hydraulicchange-over valve respectively, and the oil inlet end of hydraulicchange-over valve 6 and oil outlet end connect respectively a group oil cylinder 8, two oil cylinders 8 are connected with two ceramic plungers 9 respectively, and two ceramic plungers 9 are separately positioned in two mud pump housings 10.
Working principle of the present utility model: take supporting pressure filter as example, oil pump 1 output peak rate of flow, when the required flow of pressure filter reduces, oil pump outlet pressure P
PIncrease, when pressure is higher than remote pressure regulating valve 4 set pressure P
SThe time, remote pressure regulating valve is opened, at pressure oil P
PEffect under, PC valve 3 moves to left, the left chamber of pressure oil entering variable piston is reduced the oil pump output flow, straight ending when zero worked as P
PLess than P
SThe time, remote pressure regulating valve 4 is closed, under spring-force driven dual, PC valve 3 cores move to right, and oil is rushed down by PC valve 3 in the left chamber of variable oil cylinder, and the oil pump output flow increases, this flow matches type oil hydraulic circuit, can realize the stepless variable of YB ceramic plunger slurry pump, it can adapt to the linear change of load flow, and its bearing power and oil pump output power are complementary.
The utility model can make YB delivery side of pump power equal the output power of oil pump, has reduced significantly energy consumption, has improved efficient, has prolonged the working life of YB plunger pump.
