Description
Technical field
The utility model relates to the engine installation of filling car pump oil, especially relates to a kind of pump oil engine installation of hybrid fuel filling car.
Background technology
At present, load at the same time in the filling car of two kinds of fuel, the power of its oil pumping device is through power takeoff is taken from automobile power except that a kind of fuel, and the pump oil power of another kind of fuel is broadly divided into following three kinds: 1. unidirectional flow pump is installed as power, is used the automotive battery power supply; 2. unidirectional flow pump is installed as power, is used supporting generator powered; 3. without engine installation, only lean on the gravity oil feed of fuel.Above-mentioned mode all has problems, the unidirectional flow pump that uses the automotive battery power supply is during as power, because of homemade unidirectional flow pump performance still unstable, reliability can't ensure that if use the import unidirectional flow pump, it costs an arm and a leg, the all bad assurance of the source of goods and maintenance and repair parts, because the unidirectional flow pump power consumption is serious, also increase the loss of automotive battery in addition, influenced the life-span of automotive battery; Except having above-mentioned identical problem, also need to allot in addition the motor power supply, then the quality of generator performance will directly affect the overall performance of filling car.Simultaneously, use generator powered when refueling, according to safety requirements, it is far away electrical generator must to be moved away from 15～20 meters of filling cars, therefore uses the utmost point and inconvenient; If not working power device can only refuel by gravity flow, it is slow not only to add speed oil, and also can't connect the use filtering installation in filling conduit, and the gas filed quality is not guaranteed.
Summary of the invention
The purpose of this utility model overcomes above-mentioned the deficiencies in the prior art exactly, and a kind of pump oil engine installation of hybrid fuel filling car is provided, and this device is not only easy to use, and stable performance, the global reliability height, and cost of price is low, and refueling operation safety also is convenient to maintenance.
The purpose of this utility model realizes by following technical proposals, the pump oil engine installation of hybrid fuel filling car of the present utility model includes Hydraulic Pump, HM Hydraulic Motor, Pneumatic reversal valve, by pass valve, flow regulating valve, hydraulic reservoir, the oil return oil filter, oil inlet oil filter and hydraulic tubing, wherein by two HM Hydraulic Motor, two Pneumatic reversal valves and corresponding hydraulic tubings and and Hydraulic Pump, hydraulic reservoir, the oil return oil filter, oil inlet oil filters etc. are formed two shunt circuits, described Pneumatic reversal valve one end is communicated in Hydraulic Pump by hydraulic tubing through check valve, and Hydraulic Pump is communicated with fuel tank by hydraulic tubing through the oil inlet oil filter, and the other end of Pneumatic reversal valve is communicated in fuel tank by the oil inlet and oil return oil filter on pipeline and the pipeline; On the pipeline of gas control commutation connection fuel tank, also be provided with a by pass valve; On the pipeline of Pneumatic reversal valve, also be provided with a compression indicator in addition through being communicated in Hydraulic Pump; On the pipeline of Pneumatic reversal valve connection HM Hydraulic Motor, be provided with flow regulating valve.
The function of above-mentioned each member is as follows, and HM Hydraulic Motor is the output control mechanism of hydraulic power, provides power to fuel charger; Pneumatic reversal valve is a hydraulic control component, and it is used for realizing that by gas circuit control point fuel refuels and hybrid fuel gas filed conversion simultaneously; Being used for pump is the input mechanism of hydraulic power, and being used for by power takeoff is hydraulic power with the automobile current generator power conversion; By pass valve is to be used for automatic guidance modulated pressure system pressure inside; Flow regulating valve is used for the pressure in governor motor loop; Hydraulic reservoir is used to deposit the hydraulic oil that hydraulic efficiency pressure system is used; Hydraulic tubing is used to be communicated with each member.
The principle of work of the pump oil engine installation of hybrid fuel filling car of the present utility model is formed hydraulic efficiency pressure system by two shunt circuits, Hydraulic Pump is directly driven by power takeoff, by two Pneumatic reversal valves, control two HM Hydraulic Motor respectively, and then control the work of two oil pumps.Two HM Hydraulic Motor can work independently, and also can work simultaneously.Described flow regulating valve adopts lead sealing, must not arbitrarily adjust.The hydraulic oil trade mark is the HVN32 low temperature hydraulic oil.In two loops, all be provided with the motor that is used to test the speed in addition, drive speed gage, be used to show the rotating speed of oil pump, work being no more than under the situation of its maximum speed of revolution to guarantee oil pump, can select for use the GM5-16 HM Hydraulic Motor to drive oil pump, discharge capacity is 16ml/r, and maximum speed of revolution is 1500r/min, and required flow is 1500 * 1610-3=24L/min.Two HM Hydraulic Motor series connection are used, and its system works pressure is 16Mpa.
The utility model has the advantages that this device is not only easy to use, and stable performance, the global reliability height, cost of price is low, and refueling operation safety also is convenient to maintenance.
