Concrete condition understands the concrete meaning of the term.
As Figure 1-3, a kind of oil transfer pump, including power pump A and manual pump B；The power pump A is provided with oil inlet 1
With oil-out 2, the power pump A inside is provided with oil sucting cavity 3 and oil-discharging cavity 4, and the oil inlet 1 connects oil sucting cavity 3, described fuel-displaced
Mouth 2 connects oil-discharging cavities 4；The manual pump includes piston bore 5, the piston component 6 being slidedly assemblied in piston bore 5 and fixed
Base 7 in the bottom of piston bore 5, the piston component 6 includes handle 61, piston rod 62 and the piston 63 being sequentially connected, institute
The shank of handle 61 is stated outside manual pump B, the manual pump is connected to power pump A side, the base by base 7
Offered on 7 in the valve chamber 71 of two connection piston bore 5 inner chambers, two valve chambers 71 and be respectively fitted with line check valve 72 with going out
Oily check valve 73, the in line check valve 72 is connected with oil sucting cavity 3, and the oil outlet one-way valve 73 is connected with oil-discharging cavity 4.
The oil transfer pump that above-mentioned embodiment is provided, its manual pump B operation principle is as follows：First pull manual pump B handle
61, handle 61 drives piston rod 62 and piston 63, and opposing pistons cylinder barrel 5 is moved upwards together, now, piston 63 and piston bore 5
Vacuum is formed on bottom, and fuel oil under vacuum, is inhaled into from power pump A oil inlet 1, flows through oil sucting cavity 3, in line check valve
72 enter in piston bores 5, then push handle 61 again, and handle 61 drives piston rod 62 and piston 63 opposing pistons cylinder barrel together
5 move downward, and the fuel oil in piston bore 5 then in the presence of extruding, flows out from oil outlet one-way valve 73, flow through oil-discharging cavity 4, go out
Hydraulic fluid port 2 enters in injection pump, so pushes away, draws repeatedly, and manual pump B completes pump oil.
Explanation especially set out is needed, under normal circumstances, can directly use power pump A defeated for the injection pump of engine
Fuel oil is sent, but manual pump B can be first enabled before engine is started when running into following several situations, determination engine oil spout is waited
Pump can normal work can start engine, the power pump A is started normal work：
1st, air is entered inside oil transfer pump, the unimpeded of oil transfer pump pipeline road is influenceed, oil suction, oil extraction difficulty or oil transportation is caused not
Foot, and manual pump B can exclude air during fuel oil is conveyed, and recover the unimpeded of pipeline；
2nd, the engine long time is not used by, and pipeline road inwall is dried, and the fuel oil Castor Oil pipeline road of manual pump B conveyings
Inwall；
3rd, in the case that temperature is relatively low, the solidifying degree of the fuel oil remained in pipeline road is higher, mobility is poor, and manual pump B is defeated
The fuel oil sent can wash away pipeline inner wall when being flowed in pipeline road, gradually reduce the solidifying degree of trapped fuel, until two kinds of combustions
Oil can synchronously flow；
4th, manual pump B provides the fuel feeding environment of safety before power pump A works for engine, can make power pump A performance of feeding oil
Reach most preferably, make the start-up course of engine more smooth.
It follows that the oil transfer pump of present embodiment offer is simple in construction, simple operation, can possess above-mentioned a variety of functions,
Compared with prior art, security is higher, performance more preferably.
Further, it is the oil transfer pump more compact structure that present embodiment is provided, profile is more compact, when designing and producing,
As shown in figure 1, manual pump B can be made to be parallel to each other with power pump A, and the manual pump B is located at the side of power pump A oil inlets 1.
Further, as shown in figures 1 and 3, the power pump A includes the pump housing 8 and pump cover 9, the pump housing 8 and pump cover 9
On offer oil sucting cavity 3 and oil-discharging cavity 4（The oil sucting cavity 3 of the pump housing 8 is not drawn into oil-discharging cavity 4）, the pump cover 9 and base 7 are consolidated
Offer suction passage 91 and oil drain passage 92 on fixed connection, pump cover 9, the entrance of the suction passage 91 by oil sucting cavity 3,
Outlet is connected with line check valve 72, and the entrance of the oil drain passage 92 is connected with oil outlet one-way valve 73, exported positioned at oil-discharging cavity 4
It is interior.
Above-mentioned needs propose explanation, because manual pump B is parallel to each other with power pump A, and manual pump B is located at power pump
The side of A oil inlets 1, then relative to the oil-discharging cavity 4 on power pump A pump covers 9, oil sucting cavity 3 and goes out closer to manual pump B base 7
In processing easier design principle, the entrance of suction passage 91 should keep a determining deviation with oil sucting cavity 3（As shown in figure 3, oil suction
The entrance of passage 91 is in the top of oil sucting cavity 3）, and the outlet of suction passage 91 is then directly connected with line check valve 72（Oil suction
The outlet of passage 91 is in the side of pump cover 9）, so, drilled since the side of pump cover 9, under being not required to get into oil sucting cavity 3 just
Side, this shortens the depth of drilling, reduces the difficulty of drilling, and is conducive to manual pump B oil suctions（Shorten the stroke of oil suction）.
Further, as shown in Fig. 2 to strengthen the fastness connected between base 7 and piston bore 5, the base 7
Vertical section is in " convex " font, and the raised top of the base 7 is interference fitted with piston bore 5；And manual pump B is installed for convenience
On power pump A, the manual pump B is with power pump A using being threadedly coupled, and the bottom of base 7 symmetrically offers two screw threads
Bolt is equipped with hole 75, screwed hole 75；The top of the base 7 offers the groove 74 connected with the inner chamber of piston bore 5, two
Individual valve chamber 71 is symmetrically distributed in the lower section of groove 74, and two valve chambers 71 are connected with groove 74, therefore, fuel oil in manual pump B
Flow path be successively：In line check valve 72, groove 74, oil outlet one-way valve 73.
Preferably, the junction of the base 7 and pump cover 9 is provided with sealing gasket 10, and the sealing gasket 10 is used to prevent
Fuel leakage.
Preferably, fluid sealant 11 is provided between the barrel of the base 7 and piston bore 5, the fluid sealant 11 is used
