Description

Fork truck oil suction pipe assembly

Technical field:

The utility model relates to a kind of fork truck oil suction pipe assembly.

Background technology:

Fork truck is in work, need be that medium moves with hydraulic oil, just need suck out hydraulic oil this time in fuel tank, enter into work in the oil cylinder, present oil suction pipe assembly with the hydraulic oil sucking-off, following weak point is arranged: 1) volume is big because this assembly integrated pipelines such as a plurality of oil return pipes and oil suction pipe, make overall volume very big, be unfavorable for installing; 2) existing assembly filtering accuracy is lower, and influence enters the quality of the hydraulic oil of oil cylinder.

The utility model content:

The purpose of this utility model is at the deficiencies in the prior art part, and a kind of fork truck oil suction pipe assembly is provided, its volume is little, filtering accuracy is high, the pipe bent place not recessed flat, do not have crack, a transition nature.

Technology solution of the present utility model is as follows:

Fork truck oil suction pipe assembly comprises tank cover, and oil suction pipe, first oil return pipe, second oil return pipe are installed on the described tank cover, has a diameter to be on the described tank cover

Through hole, be welded with a threaded line pipe on this through hole; Also have a diameter to be on the described tank cover

Circular hole, be welded with a permeability cell on this circular hole.

Described fork truck oil suction pipe assembly is welded with an adapter plate in the sucking hole of described oil suction pipe, this adapter plate is provided with a bolt; Be welded with an oil filter element shell on the outer circumference surface of sucking hole, this oil filter element shell is built-in with filter screen.

Described fork truck oil suction pipe assembly, described first oil return pipe is No. 20 solid drawn tubes, and the fuel-displaced mouth of pipe of this oil return pipe is 30 ° of beveled mouth.

The filtering accuracy that described fork truck oil suction pipe assembly, described oil filter element shell are built-in with filter screen be 120 orders/time.

Described fork truck oil suction pipe assembly, described second oil return pipe is

No. 20 solid drawn tubes, and the fuel-displaced mouth of pipe of this oil return pipe is 30 ° of beveled mouth.

The utility model beneficial effect is:

1) fork truck oil suction pipe assembly of the present utility model is compared with existing oil suction pipe assembly, pipelines such as oil suction pipe, oil return pipe and freeing pipe all are fixed on the tank cover, the convenience of ten minutes in the time of installation, and also volume is little, the volume ratio like product has dwindled about 10%, and being convenient to very installed.

2) the utility model is at the curve of each pipe, transition steadily, do not have recessed flat place, help the smooth flow of hydraulic oil, can not make because of the conversion of pipeline have the phenomenon of turbulent flow to produce.

3) the fuel-displaced mouth of pipe of the utility model oil return pipe is 30 ° of beveled mouth, make the area of the fuel-displaced mouth of pipe increase by one times, its flow velocity has reduced the generation of bubble when helping reducing oil return greatly under equal flow, reduce the back pressure of oil return line when more helping oil return, reduce cal val.

4) filtering net in the utility model is 120 orders, filtering accuracy height, the cleaning that can guarantee to enter in-oil cylinder hydraulic oil.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is described further:

Fig. 1 is a main diagrammatic sketch of the present utility model;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the birds-eye view of Fig. 1.

The specific embodiment:

The following stated is preferred embodiment of the present utility model only, is not that scope of the present utility model is limited.

Embodiment, see accompanying drawing 1～3: fork truck oil suction pipe assembly, comprise tank cover 1, oil suction pipe 2, first oil return pipe 3, second oil return pipe 4 are installed on the described tank cover, there is a diameter to be on the described tank cover 1

Through hole 101, be welded with a threaded line pipe 5 on this through hole; Also have a diameter to be on the described tank cover 1

Circular hole 102, be welded with a permeability cell 6 on this circular hole.

Be welded with an adapter plate 7 in the sucking hole of described oil suction pipe 2, this adapter plate is provided with a bolt 8; Be welded with an oil filter element shell 9 on the outer circumference surface of sucking hole, this oil filter element shell is built-in with filter screen 10.

Described first oil return pipe 3 is

No. 20 solid drawn tubes, and the fuel-displaced mouth of pipe of this oil return pipe is 30 ° of beveled mouth.

The filtering accuracy that described oil filter element shell 9 is built-in with filter screen 10 be 120 orders/time.

Described second oil return pipe 4 is

No. 20 solid drawn tubes, and the fuel-displaced mouth of pipe of this oil return pipe is 30 ° of beveled mouth.
