Cross in the oil that exhaust pipe is fallen directly into oil pump, make in this way in fuel tank oil it is impacted, impurity by oil pump inspiration, meeting and cause
Machinery it is stuck and shuts down or burn motor or even fire, cause the damage of oil pump.
Utility model content
The purpose of the utility model is to overcome current oil pump in use, the impurity in air can pass through row
Enter in oil pump at gas port, pollution oil, cause machinery is stuck shut down, make the problem of oil pump service life reduction, and provide one
It kind can prevent the oil pump filter device that sand and dust are fallen into, which installs a strainer and dust-proof additional by the exhaust ports of oil pump
Cover, can effectively filter the granular substances such as the sand and dust in air, impurity is prevented to be mixed into oil, ensure that product exists
During use will not because impurity is mixed into grease and caused by machinery it is stuck and shuts down, avoid oil pump and shut down and unexpectedly send out
It is raw, improve the service life of oil pump.
The utility model is realized in this way：It is a kind of to prevent the oil pump filter device that sand and dust are fallen into, including oil pump sheet
Body, the exhaust ports of the oil pump body are provided with pedestal, and pedestal lower part is embedded in exhaust outlet, and being provided in the pedestal makes sky
The channel that air-flow leads to is provided with strainer in channel, dust cover is provided with above the strainer, is uniformly provided on dust cover logical
Hole.
Preferably, the reserved opening connected with channel is provided on the side wall of the pedestal, strainer is installed on bottom by reserved opening
On seat.
Preferably, the edge of the strainer is provided with the baffle of semicircular, and the baffle is equal with the height of reserved opening.
Preferably, the upper surface of the baffle is provided with arc groove, is contacted in the reserved opening with baffle upper surface
Position is provided with arc convex, and the baffle is installed in by arc groove, arc convex at reserved opening.
Preferably, external screw thread is provided on the lateral wall on the pedestal top, the dust cover madial wall is provided with interior spiral shell
Line, dust cover are installed on by screw thread on pedestal.
Preferably, the lower end of the pedestal is set with rubber layer, and pedestal is embedded in by rubber layer in exhaust outlet.
Preferably, the dust cover is horn-like in upper end is small, lower end is big.
The utility model has the following advantages that：The oil pump filter device that can prevent sand and dust from falling into of the utility model leads to
The exhaust ports for crossing oil pump install a strainer and dust cover additional, the granular substances such as the sand and dust in air can be carried out effectively
Filtering, impurity is prevented to be mixed into oil, ensure product in use will not because impurity is mixed into grease and caused by machinery
It is stuck and shut down, it avoids oil pump and shuts down the unexpected service life for occurring, improving oil pump.
