Abstract
The utility model relates to a manual oil transfer pump, comprising an oil-in pipe joint, an oil-out pipe joint and a pump body in the middle, wherein the pump body is an elastic sac-shaped compressible pump body and an oil-in one-way valve and an oil-out one-way valve are respectively arranged on the oil-in pipe and the oil-out pipe. The oil transfer process is realized by cooperating with the elastic compressible pump body, the oil-in pipe with the oil-out pipe and pressing the elastic pump body. The manual oil transfer pump has features of simple structure, relative light material, convenient use and relative high efficiency.
Description
Technical field
The utility model relates to a kind of oil transfer pump, relates in particular to a kind of hand and loses oil pump.
Background technique
In oil-fired system, the effect that hand is lost oil pump is very important, when change fuel oil fitering element, clean the fuel oil fuel tank, all will be after the maintenance of Injection Pump specialty at first to the oil-way system emptying, ato unit smoothly then, the main effect of hand oil pump is with the fuel path system evacuation at this moment; When automobile when changing fuel filter, oil-fired system is in the oil starvation state, automobile can't start, just needing to use hand to lose oil pump this moment will be full of whole oil-fired system in the fuel from fuel tank.Traditional hand is lost oil pump and is adopted Structural Hardware, Heavy Weight, and the structure heaviness needs to use outer being fastened on the vehicle frame, is not easy to use.
Summary of the invention
The purpose of this utility model provides a kind of light-weighted hand and loses oil pump, loses oil pump structure bulky complex, inconvenient problem with use to solve traditional hand.
For achieving the above object, the utility model adopts following technological scheme: a kind of hand is lost oil pump, this oil transfer pump comprises inlet connector, flowline connection to subsea and the middle pump housing thereof, but the described pump housing is the resilient bladder breathing pump housing, and its oil inlet pipe and oil outlet tube place correspondence respectively are provided with in line check valve and fuel-displaced one-way valve.
Described in line check valve and fuel-displaced one-way valve are ball valve.
But the described pump housing is the thermoplastic elastic breathing pump housing.
The conducting direction of described in line check valve and fuel-displaced one-way valve all is to fuel-displaced direction by oil-feed.
Hand of the present utility model loses that oil pump adopts the resiliency compressible pump housing and into and out of the cooperation of oily one-way valve, by press the compression elasticity pump housing, and realization oil transportation process, it is simple in structure, and material is lighter, and is easy to use and efficient is higher.
Description of drawings
Fig. 1 is the structural representation that the utility model hand is lost oil pump embodiment.
Embodiment
Below in conjunction with specific embodiment the utility model is described further.
Be illustrated in figure 1 as the utility model hand and lose the structural representation of the specific embodiment of oil pump, this oil transfer pump comprise oil inlet pipe 1, oil outlet tube 7 and between the pump housing 4, the pump housing 4 is the resiliency compressible pump housing, the oil inlet pipe 1 of the pump housing and oil outlet tube 7 places correspondence respectively are provided with in line check valve 2 and fuel-displaced one-way valve 6, in line check valve 2 and fuel-displaced one-way valve 6 are installed by corresponding oil-feed valve seat 3 and delivery valve seat 5 respectively, and in line check valve 2 and oil-feed valve seat 3 and fuel-displaced one-way valve 6 and delivery valve seat 5 complement each other to form sealing respectively.
The material of the pump housing 4 adopts thermoplastic elastomer (TPE), has oil resistant, continuous pressing function; The material of oil inlet pipe 1, oil outlet tube 7 and corresponding oil-feed valve seat 3 and delivery valve seat 5 all adopts nylon, in line check valve 2 and fuel-displaced one-way valve 6 adopt oil-resistant rubber material, entire product does not contain any metallic material, more traditional product weight reduces more than 80%, and this product can proper functioning between-40 ℃ to 120 ℃.
Working principle of the present utility model and working procedure are as follows: push the pump housing 4 air in the chamber is discharged, unclamp the pump housing 4, form vacuum in the chamber, fuel oil is opened in line check valve 2 by oil inlet pipe 1 from transport pipe, enter in the pump housing chamber, at this moment be full of fuel oil in the pump housing chamber, this process is the oil-feed process; Push the pump housing 4 once more, fuel oil is opened fuel-displaced one-way valve 6 in the chamber, enters in the transport pipe by oil outlet tube 7, and this process is fuel-displaced process.After fuel oil is full of the pump housing, pushes at every turn and all will realize oil-feed process and fuel-displaced process.Oil-feed valve seat 3 and delivery valve seat 5 are used for fixing ball in line check valve 2 and fuel-displaced one-way valve 6 respectively, and limit its displacement, reach good pump oil effect with it.In fuel-displaced process, in line check valve 2 cooperates the formation sealing with oil-feed valve seat 3, and fuel oil can not flow out from oil inlet pipe 1.In the oil-feed process, fuel-displaced one-way valve 6 cooperates the formation sealing with delivery valve seat 5, and fuel oil can not be inhaled in the pump housing 4 from oil outlet tube.
Hand of the present utility model loses that oil pump adopts the resiliency compressible pump housing and into and out of the cooperation of oily one-way valve, by press the compression elasticity pump housing, and realization oil transportation process, it is simple in structure, and material is lighter, and is easy to use and efficient is higher.
In line check valve of the present utility model and fuel-displaced one-way valve all adopt ball valve, also can adopt cone valve or umbrella valve, and this conversion belongs to those skilled in the art's common technology means, drops within the protection domain of the present utility model.
The pump housing adopts thermoplastic elastomer (TPE) TEEE, but the pump housing is the elliposoidal resilient bladder breathing pump housing, and its minor axis dimension is controlled at 30-60mm, and major axis dimension is controlled at 40-80mm, and wall thickness is controlled at 1mm to 1.5mm.This hand is lost can be between-40 ℃ to the 120 ℃ long-time proper functioning of oil pump.Can in diesel oil and brake wet goods medium, work for a long time.
Claims (4)
1. a hand is lost oil pump, it is characterized in that: this oil transfer pump comprises inlet connector, flowline connection to subsea and the middle pump housing thereof, but the described pump housing is the resilient bladder breathing pump housing, and its oil inlet pipe and oil outlet tube place correspondence respectively are provided with in line check valve and fuel-displaced one-way valve.
