Abstract
The utility model discloses a hydraulic oil mass distribution system of a hydraulic power air conditioner for machineshop truck, which belongs to an air conditioner for machineshop truck. The system includes a main engine hydraulic pump, a speed control valve, an air conditioner motor, a shaft coupling, an air conditioning compressor, a rotary cushion valve, a rotary motor, a tank and a proportional valve. The oil-inlet of the proportional valve is associated with the mainframe equipped with an air-conditioning system. The oil outlet includes two parts, one is connected with rotary motor by hydraulic lines and the speed control valve, and the other one is connected with an air conditioning motor by the hydraulic lines and the rotary cushion valve. The utility model has advantages of adopting a proportional distribution valve to control the distribution ratio of hydraulic oil from the hydraulic pump, and respectively add the hydraulic oil to the speed control valve and the rotary cushion valve in proportion. The structure of which is simple, economize cost of the air-conditioning system and effectively improve reliability of the air-conditioning system.
Description
Technical field
The utility model relates to the engineering auto air-con, specifically is a kind of hydraulic-oil quantity distribution system for engineering vehicle hydraulic power air-conditioner.
Background technique
Present hydraulic power air conditioner for engineering vehicle system, its hydraulic part is connected in the oil return circuit of main frame, when the main frame recirculating oil quantity increases, air-conditioning system work will produce big system pressure, cause load on host computers excessive, so when using air-conditioning, will certainly influence the main frame rotation, the phenomenon that host work is short of power appears, also can cause problems such as crossing the explosion of ambassador's hydraulic pipe line because of system pressure when serious.
Summary of the invention
The purpose of this utility model provides a kind of hydraulic-oil quantity distribution system for engineering vehicle hydraulic power air-conditioner.To overcome the above-mentioned defective of prior art.Structural design is simple and possess higher operational safety
The utility model is achieved by the following technical solution: a kind of hydraulic-oil quantity distribution system for engineering vehicle hydraulic power air-conditioner, this system comprises the main frame oil hydraulic pump, series flow control valve, the air-conditioning motor, coupling, air condition compressor, rotary buffering valve, rotary motor, fuel tank also comprises the pro rate valve, and the filler opening of pro rate valve links with the oil hydraulic pump that the air-conditioning system main frame is housed, oil outlet divides the two-way parallel connection: leading up to hydraulic pipe line and series flow control valve is connected with rotary motor, and another road is connected with the air-conditioning motor by hydraulic pipe line and rotary buffering valve.
The hydraulic oil of this hydraulic-oil quantity distribution system because of having adopted the control of pro rate valve to come out from oil hydraulic pump, enter air-conditioning series flow control valve and main frame rotation trimmer valve after the passing ratio distributing valve pro rate again, when the hydraulic oil power of guaranteeing to enter the main frame trimmer valve can make main frame revolution motor proper functioning, utilized the power more than needed on the main frame to make air-conditioning work realize refrigeration again.
The utility model has the advantages that: adopt the pro rate valve to control the allocation proportion of the hydraulic oil that from oil hydraulic pump, comes out, and make it send into series flow control valve and rotary buffering valve to hydraulic oil respectively in proportion, structural design is simple, reduced the cost of air conditioner, well improve the operational safety of air-conditioning system, prolonged the working life of air-conditioning system.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model structural representation.
1. oil hydraulic pumps among the figure, 2. pro rate valve, 3. series flow control valve, 4. air-conditioning motor, 5. coupling, 6. air condition compressor, 7. rotary buffering valve, 8. rotary motor, 9. fuel tank.
Embodiment
As shown in drawings, pro rate valve 2 filler openings connect main frame oil hydraulic pump 1, the oil outlet of pro rate valve 2 is divided into two-way in parallel, leading up to hydraulic pipe line and main frame rotary buffering valve 7 is connected with rotary motor 8, another road is connected with air-conditioning motor 4 by hydraulic pipe line and air-conditioning series flow control valve 3, and hydraulic oil flows into main frame oil sump tank 9 after each pipeline is flowed through each parts; Air-conditioning oil hydraulic motor 4 is with connecting by elastic coupling flexible coupling 5 between the air condition compressor 6.
This system works principle is: during air-conditioning work, pro rate valve 2 is shunted flow through the hydraulic oil that comes from the main frame oil hydraulic pump in proportion according to the hydraulic-oil quantity allocation proportion (present embodiment is set 7: 3) of prior setting, and flowing into the rotary buffering valve 7 of main frame, the series flow control valve 3 of air-conditioning system respectively, oil return afterwards is to main frame fuel tank 9.In this process, both guaranteed the normal operation of main frame rotary motor 8, make air condition compressor 6 proper functioning under the driving of air-conditioning oil hydraulic motor 4 realize refrigerating function again.
