An oil pump can effectively operate for a long time by the aid of the oil sucking filter, and oil can be continuously purified and filtered during circulation by the aid of the three stages of filter elements with different filtering precisions, thereby achieving the effects of online purification and filter. The multistage purifying oil filter adopts the high-flow filter elements, omits various oil tanks and operation valves which are used for sedimentation, is simple in structure, small in volume and low in manufacturing cost, and can realize long-term and stable circulatory filter without frequently replacing the filter elements. Each filter element is provided with a pressure gauge, an exhaust joint and a pressure-measuring hose, thereby bringing convenience for detection and maintenance.
Description
Technical field
The utility model relates to the online in the course of the work circulating filtration of a kind of purification plant of hydraulic oil, particularly hydraulic system and guarantees the multistage purification oil filter of hydraulic system oil liquid turbidity test.
Background technique
The pollution of fluid is the main cause that causes hydraulic system and mechanical failure in the hydraulic system, so hydraulic system must keep the cleaning of its fluid just can reach best working efficiency, practice result shows, filter precision is brought up to 30 microns from 40 microns, machinery and hydraulic element wearing and tearing can reduce 50%, if improve 15 microns again, machinery and hydraulic pressure wearing and tearing can reduce 75%, the turbidity test of hydraulic oil improve one-level, will prolong ten times the working life of hydraulic system primary component.
The patent No. 200420061594.9 " machine oil filtration, purification recycling plant ", though a kind of purification plant that machine oil is filtered and recycles also is provided, but its structure is complicated, need to increase a plurality of fuel tanks, pipeline, oil transfer pump and the valve of same-action not, also need to refilter through post precipitation repeatedly, whole device volume is big, occupies the very big useful space, uses, operates, keeps in repair trouble.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of multistage purification oil filter is provided, utilize the filter of different accuracy, the recirculation after multistage purification filters the change cleaning of contaminated hydraulic oil is used, improved the quality of hydraulic system oil liquid, thereby guarantee hydraulic system and equipment long-term stability, operation, and the working life of having improved equipment reliably.
The technical scheme in the invention for solving the above technical problem is: the multistage purification oil filter, comprise the Oil pump electrical machinery group, fuel tank, multistage filter, described Oil pump electrical machinery group is a low pressure cycloidal gear Oil pump electrical machinery group, described fuel tank is the tank drainback district and the fuel tank oil suction district of hydraulic system, described multistage filter is by the oil suction filter, one, two, three grades of filter cores constitute, one end of described oil suction filter is connected with the tank drainback district, the other end is connected to the inlet port of low pressure cycloidal gear Oil pump electrical machinery group, the oil outlet of low pressure cycloidal gear Oil pump electrical machinery group is connected to the filler opening of one-level filter core, the oil outlet of one-level filter core is connected to the filler opening of secondary filter core, the oil outlet of secondary filter core is connected to the filler opening of three grades of filter cores, and the oil outlet of three grades of filter cores is connected to the oil suction district of fuel tank.
Compared with prior art, advantage of the present utility model is: this purifies in the oil filter and has adopted low pressure cycloidal gear oil pump, the contamination resistance height of itself, suction capacity is strong, be adapted at working in the more abominable fluid environment, and guarantee the permanently effective work of oil pump, again the fluid filter core of three grades of different filter precisioies by the back by the oil suction filter, make fluid constantly constantly purify, filter in the cyclic process, thereby reach the in-line purification filtering effect.This device has adopted the filter core of big flow, and has saved the various fuel tanks and the operated valve of precipitation usefulness, and is simple in structure, volume is little, fabricating cost is low, needn't be frequently when guaranteeing this system works renew cartridge more, can be long-term and stable carry out circulating filtration.For guaranteeing the normal use of filter core, a pressure gauge and exhaust joint, pressure measurement flexible pipe all directly are installed on the filter cylinder of each filter core, on operation panel, all can observe directly the variation of force value, thereby judge the working condition of filter core, be convenient to detection and maintenance, reduced cost of production, simple, convenient.In addition, this purification oil filter can be made fixed or portable, and movable type can be placed this device in the position that can put arbitrarily and be filtered, and uses flexible, convenient, hydraulic system is through this multistage hyperfiltration system filtration, the working life of having improved equipment greatly.
