C. engine oil filter cleaner import and the pipeline that single chamber air pulsing diaphragm pump is connected to fluid storage tank; Single chamber air pulsing diaphragm pump is connected to I. C. engine oil filter cleaner inlet ductwork fine filtrator, pressure gauge and rapid pipe joint.Return liquid system comprises that single chamber air pulsing diaphragm pump is connected to the pipeline of I. C. engine oil drain pan oil drainage hole and the pipeline that single chamber air pulsing diaphragm pump is connected to fluid storage tank; Single chamber air pulsing diaphragm pump is connected on the pipeline of I. C. engine oil drain pan oil drainage hole coarse-grain filtering device and rapid pipe joint; The pipeline that single chamber air pulsing diaphragm pump is connected to fluid storage tank has fine filtrator.
The utlity model has following advantage:
1. because washing unit is the pneumatic pump that adopts a kind of single cell structure, therefore simply be easy to do, use and keep in repair extremely conveniently, and performance is good, and cost is low.
2. because washing unit adopts two single chamber air pulsing diaphragm pumps, make feed liquor and return liquid system and fluid storage tank can form two independently pipe-line systems, also can form the circulatory system, therefore simple, convenient, need not to select valve, leakage point is few, and fault is handled easily.
3. because equipment is simple, easily operation, so the cleaning method of this device fast saves time, rationally effectively.
Structure of the present utility model, characteristics and advantage thereof can be described in more detail by following examples with reference to accompanying drawing.
Accompanying drawing 1 is the structural representation of most preferred embodiment of the present utility model.
Accompanying drawing 2 is structural representations of a kind of single chamber air pulsing diaphragm pump.
As shown in Figure 1, single chamber air pulsing diaphragm pump 2 is positioned at the feed liquor system of device, and single chamber air pulsing diaphragm pump 11 is positioned at the return liquid system of device.The feed liquor system comprises: fluid storage tank 1 and fluid storage tank outlet 19 are to the connecting pipeline of the inlet 20 of single chamber air pulsing diaphragm pump 2; The outlet 21 of single chamber air pulsing diaphragm pump 2 is to the connecting pipeline of I. C. engine oil filter cleaner inlet 8.In order to guarantee that the cleaning solution that enters internal-combustion engine avoids sneaking into impurity, also is equipped with a 3m oil strainer 4 on this pipeline; For pipeline is carried out pressure protect, also adorned a pressure gauge with electric contact 5 in the pipeline, when pressure surpassed specified value, control valve 3 was cut off in electrical signal immediate feedback meeting, and pneumatic pump 2 is quit work.The feed liquor pipeline is connected with the pipeline of internal-combustion engine inlet, adopts a rapid pipe joint 6.Return liquid system comprises the connecting pipeline of I. C. engine oil drain pan oil drainage hole 9 to the inlet 22 of single chamber air pulsing diaphragm pump 11, and rapid pipe joint 6 is housed on this pipeline; For the liquid impurity after preventing to clean enters pneumatic pump, coarse-grain filtering device 10 has been installed before going into pump, return liquid system also comprises the connecting pipeline of the outlet 23 of single chamber air pulsing diaphragm pump 11 to the inlet 24 of fluid storage tank 1,3m fine filtrator 13 also is housed on this pipeline, has guaranteed to get back to the filter quality of the cleaning solution of fluid storage tank 1.
