Abstract
The invention discloses a flame retardant oil filter. A protection filter is installed on the basis of a traditional filtering device, oil passing through a fine filter is filtered again, and the use cost is reduced by sacrificing the low-cost protection filter to realize the prolongation of the service life of the high-cost fine filter. Two ends of an oil pump are connected with an overpressure protection non-return valve in parallel, and an internal circulation of the oil is formed in the oil pump when the pressure of the oil in the pipeline of the filtering device to protect the filtering device; and when the pressure of the oil in the pipeline further rises, and the filtering device is protected through the control of the oil output flow of the oil pump by a pressure controller or the closure of the oil pump. A heater is installed in the protection filter, so oil having a large viscosity can be heated to reduce the viscosity of the oil and improve the filtering efficiency of the oil. Compared with oil filters in the prior art, the flame retardant oil filter has the substantial advantages of low use cost, high safety and high oil filtering efficiency.
Description
Technical field
This invention relates to a kind of filter, particularly a kind of fire resistant oil oil filter.
Background technology
Various fluid producing, deposit, have unavoidably in transportation and the course of work solid impurity and sneak into fluid and cause the pollution of fluid, therefore fluid must filter before use.But current existing oil filtering device only has inlet filter to oil pump then to pass through fine filter, filters out impurities.The filter core of the fine filter of this class oil filtering device easily stops up, and causes the pipeline oil hydraulic coupling of filter constantly to raise and cannot work until cause filter to damage.Inlet filter can only filter solid particle polluter larger in fluid, and remaining impurity filters by fine filter, therefore in use procedure, needs frequently to change fine filter filter core, because fine filter filter core cost compare is high, causes the use cost of filter higher.The ratio of viscosities of some fluid is higher, causes the efficiency of fluid by filter element lower and cause oil liquid pressure in pipeline to raise.
Summary of the invention
1, need the technical problem of solution
The object of this invention is to provide the fire resistant oil oil filter that a kind of filter efficiency is high, use cost is low, safe and reliable.
2, technical scheme
A kind of fire resistant oil oil filter, comprises the inlet filter, oil pump and the fine filter that are serially connected in successively in working connection, is provided with protection filter between described oil pump and fine filter.Described protection filter can filter out a part by the slightly bigger solid impurity of volume of inlet filter, again filtering and can filter out solid impurity tiny in fluid by fine filter.By the method for this increase protection filter, can greatly extend the service life of fine filter filter core, and the cost ratio fine filter filter core low price of protection filter element many, therefore can greatly reduce the use cost of filter.
Oil pressure when filter core stops up in oil filter oil circuit constantly raises; in order to prevent, because stopping up, filter core cause filter to damage; oil-in at described oil pump oil-in, described protection filter oil-in and fine filter is respectively equipped with Pressure gauge; for observing the pressure of oil filter oil circuit each several part fluid, when the Pressure gauge numerical value of protection filter oil-in reaches certain value, explanation has needed to change protection filter core.
In order to prevent Pressure gauge fault or operating personnel, do not splash the manometric too high damage equipment of oil liquid pressure that causes, the check valve of an overpressure protection in parallel at described oil pump two ends.When filter core stops up; oil liquid pressure between oil pump and protection filter in pipeline is elevated to the force value of setting; one-way valve opens part fluid returns to the input of oil pump, and the interior circulation of forming section fluid in oil pump, to protect whole filter to avoid because hypertonia is damaged original paper.
Between described protection filter and oil pump, be provided with the pressure controller of control oil pump.When the filter core of filter further stops up; the pressure of the interior circulation fluid by oil pump still continues to raise; when force value reaches the numerical value that pressure controller sets, pressure controller protects whole filter to avoid because the too high damage original paper of oil liquid pressure by the method that reduces the flow of oil pump output fluid or cut out oil pump.
In order to reduce oil viscosity, improve the filter efficiency of protection filter, by being also equipped with for heating fluid to reduce the heater of oil viscosity between described protection filter and oil pump.
In order further to reduce use cost, inlet filter is wire netting capable of washing.
Operation principle of the present invention: a kind of fire resistant oil oil filter; on basis by the filter traditional, increase a set of protection filter; for the method for again filtering by the fluid of fine filter, extend the service life of fine filter, to sacrifice the method for protecting cheaply filter to exchange the prolongation in service life of expensive fine filter for, reduce use cost.The check valve of overpressure protection in parallel at oil pump two ends, forms the interior circulation of fluid in oil pump with protection filter when oil liquid pressure raises in filter pipeline; When oil liquid pressure in pipeline further raises, the flow by pressure controller control oil pump output fluid or close the method protection filter of oil pump; By above duplicate protection, greatly improved the reliability of filter.Mounting heater between protection filter and oil pump, the method for passing through to heat for the larger fluid of viscosity reduces the filter efficiency of oil viscosity raising fluid.
3, beneficial effect
Compared with prior art, its remarkable advantage is: 1, use cost is low in the present invention; 2, safe; 3, fluid filter efficiency is high.
Accompanying drawing explanation
Fig. 1 is control principle drawing of the present invention
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in the figure, a kind of fire resistant oil oil filter, comprises the inlet filter 1, oil pump 2, protection filter 4 and the fine filter 3 that are serially connected in successively in working connection.Described inlet filter 1 is wire netting capable of washing, stops solid particle larger in unpurified oil to enter oil pump 2.The fluid that enters fine filter 3 is further filtered by protection filter 4, reduce the burden of fine filter 3.In order to reduce oil viscosity, improve the filter efficiency of protection filter 4, by the heater 5 for heating fluid is installed between described protection filter 4 and oil pump 2.Oil pressure when filter core stops up in oil filter oil circuit constantly raises; in order to prevent, because stopping up, filter core cause filter to damage; oil-in at described oil pump 2 oil-ins, described protection filter 4 oil-ins and fine filter 3 is respectively equipped with Pressure gauge 8; for observing the pressure of oil filter oil circuit each several part fluid, when the Pressure gauge numerical value of protection filter 4 oil-ins reaches certain value, explanation has needed to change protection filter core.For what prevent that Pressure gauge 8 faults or operating personnel from not splashing Pressure gauge 8, cause the too high damage equipment of oil liquid pressure, at the check valve 6 of a described oil pump 2 two ends overpressure protection in parallel; And between described protection filter 4 and oil pump 2, be provided with the pressure controller 7 of control oil pump 2; By dual-pressure protection, guarantee that filter is safe and reliable.
