Abstract
The utility model discloses an oil liquid filter device, which is added with a set of protective filter based on a traditional filter device, filters oil liquid passing through a fine filter again, and reduces using cost by prolonging service life of the high-cost fine filter by sacrificing the low-cost protective filter. Two ends of an oil pump are in parallel connection with an overpressure protection one-way valve, and when oil liquid pressure in pipelines of the filter device rises, inner circulation of the oil liquid in the oil pump is formed to protect the filter device. When the oil liquid pressure in pipelines further rises, flow of the oil liquid outputted by the oil pump is controlled through a pressure controller or closing of the oil pump, and accordingly the filter device is protected. A heater is arranged in the protective filter, oil liquid with large viscosity is heated to lower the viscosity and further improve filter efficiency of the oil liquid. Compared with the prior art, the oil liquid filter device has the advantages of being 1 low in using cost; 2 high in safety; and 3 high in oil liquid filtering efficiency.
Description
Technical field
This model utility relates to a kind of filtrating equipment, particularly a kind of filtrating equipment that is used for various liquid fluid.
Background technique
Various fluid are being produced, are being deposited, having solid impurity unavoidably in transportation and the working procedure and sneak into the pollution that fluid causes fluid, so fluid must filter before use.But present existing fluid filtrating equipment has only inlet filter to oil pump to pass through secondary filter then, filters out impurities.The filter core easy blocking of the secondary filter of this type fluid filtrating equipment causes continuous rising of pipeline oil liquid pressure of filtrating equipment can't work up to causing filtrating equipment to damage.Inlet filter can only filter solid particle polluter bigger in the fluid, and remaining impurity filters through secondary filter, so needs frequent change secondary filter filter core in the using process, because secondary filter filter core cost is than higher, the user cost that causes filter is than higher.The ratio of viscosities of some fluid is higher, causes the efficient of fluid through filter element lower and cause that oil liquid pressure raises in the pipeline.
Summary of the invention
Goal of the invention: the purpose of the utility model provides a kind of filter efficiency height, low, the safe and reliable fluid filtrating equipment of user cost.
Technological scheme: a kind of fluid filtrating equipment, comprise the inlet filter, oil pump and the secondary filter that are serially connected in successively in the working connection, be provided with the protection filter between said oil pump and the secondary filter.Said protection filter can filter out the volume slightly bigger solid impurity of a part through inlet filter, can filter out solid impurity tiny in the fluid through filtering once more of secondary filter.Can prolong working life of secondary filter filter core greatly through the method for this increase protection filter, and the price of protection filter element than secondary filter filter core low price many, therefore can reduce the user cost of filtrating equipment greatly.
Oil pressure when filter core stops up in the oil filter oil circuit constantly raises; Because stopping up, filter core cause filter to damage in order to prevent; Filler opening at said oil pump filler opening, said protection filter filler opening and secondary filter is respectively equipped with pressure gauge; Be used for observing the pressure of oil filter oil circuit each several part fluid, explanation has needed to change the protection filter core when the pressure gauge numerical value of protection filter filler opening reaches certain value.
Do not splash the manometric too high damage equipment of oil liquid pressure that causes, the one-way valve of an overpressure protection of parallel connection in order to prevent pressure gauge fault or operator at said oil pump two ends.When filter core stops up; Oil liquid pressure between oil pump and the protection filter in the pipeline is elevated to the force value of setting; One-way valve opens part fluid returns the input end of oil pump, forms the interior circulation of part fluid in oil pump, to protect whole filtrating equipment to avoid because overpressure is damaged original paper.
Be provided with the pressure controller of control oil pump between said protection filter and the oil pump.When the filter core of filter further stops up; The pressure of the interior circulation fluid through oil pump still continues to raise; When force value reached the numerical value of pressure controller setting, pressure controller protected whole filtrating equipment to avoid because the too high damage original paper of oil liquid pressure through flow that reduces oil pump output fluid or the method for cutting out oil pump.
In order to reduce the filter efficiency that oil viscosity improves the protection filter, be used to heat fluid to reduce the heater of oil viscosity through between said protection filter and oil pump, also being equipped with.
In order further to reduce user cost, inlet filter is a wire netting capable of washing.
The working principle of the utility model: a kind of fluid filtrating equipment; Through on the basis of traditional filtrating equipment, increasing by a cover protection filter; The method of filtering once more for the fluid through secondary filter prolongs the working life of secondary filter, reduces user cost to sacrifice the method that prolongs in working life of protecting filter to exchange expensive secondary filter for cheaply.The one-way valve of parallel connection overpressure protection at the oil pump two ends forms the interior circulation of fluid in oil pump with the protection filtrating equipment when oil liquid pressure raises in the filtrating equipment pipeline; When oil liquid pressure in the pipeline further raises, perhaps close the method protection filtrating equipment of oil pump through the flow of pressure controller control oil pump output fluid; Improved the reliability of filtrating equipment greatly through above duplicate protection.Between protection filter and oil pump, heater is installed, is reduced the filter efficiency of oil viscosity raising fluid for the bigger fluid of viscosity through the method for heating.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: 1, user cost is low; 2, safe; 3, the fluid filter efficiency is high.
Description of drawings
Fig. 1 is the utility model control principle figure.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in the figure, a kind of fluid filtrating equipment comprises the inlet filter 1, oil pump 2, protection filter 4 and the secondary filter 3 that are serially connected in successively in the working connection.Said inlet filter 1 is a wire netting capable of washing, stops solid particle bigger in the unpurified oil to get into oil pump 2.The fluid that gets into secondary filter 3 is further filtered through protection filter 4, reduce the burden of secondary filter 3.In order to reduce the filter efficiency that oil viscosity improves protection filter 4, through the heater 5 that is used to heat fluid is installed between said protection filter 4 and oil pump 2.Oil pressure when filter core stops up in the oil filter oil circuit constantly raises; Because stopping up, filter core cause filter to damage in order to prevent; Filler opening at said oil pump 2 filler openings, said protection filter 4 filler openings and secondary filter 3 is respectively equipped with pressure gauge 8; Be used for observing the pressure of oil filter oil circuit each several part fluid, explanation has needed to change the protection filter core when the pressure gauge numerical value of protection filter 4 filler openings reaches certain value.Cause the too high damage equipment of oil liquid pressure, the one-way valve 6 of an overpressure protection of parallel connection for what prevent that pressure gauge 8 faults or operator from not splashing pressure gauge 8 at said oil pump 2 two ends; And between said protection filter 4 and oil pump 2, be provided with the pressure controller 7 of control oil pump 2; Guarantee that through the dual-pressure protection filtrating equipment is safe and reliable.
