Abstract
The invention discloses a control system of a vehicle hydraulic power air conditioner, which belongs to vehicle air conditioners. The system comprises a compressor, a hydraulic pump, a hydraulic motor and a plug-in logical valve, wherein the hydraulic pump of a vehicle is connected with the hydraulic motor through the plug-in logical valve, so that the compressor works through the hydraulic motor which is driven by utilizing the high-pressure oil discharged from the hydraulic pump to realize refrigeration. The invention has the advantages that the plug-in logical valve is in a conical valve core structure, can improve the anti-clamping capability, has self cleaning capability and avoids the heating of a hydraulic system due to overlarge system pressure loss. The control system has simple structure, saves the cost of an air-conditioning system, and effectively improves the reliability of using the air-conditioning system.
Description
Technical field
The present invention relates to a kind of car air-conditioner, specifically is a kind of control system of vehicle hydraulic power air conditioner.By the plug-in logical valve Hydraulic Pump of vehicle and HM Hydraulic Motor are linked, make compressor operating, realize refrigeration thereby the high pressure oil that utilizes Hydraulic Pump to discharge drives HM Hydraulic Motor.
Background technology
Its hydraulic part of control system of vehicle hydraulic power air conditioner is connected in the oil return circuit of main frame at present, generally adopts the plug-in guiding valve to connect.Owing to produce wearing and tearing in each hydraulic unit long-term work process, cause card valve phenomenon; The flowrate variation amplitude causes the system pressure loss too big more greatly, makes the hydraulic efficiency pressure system heating.
Summary of the invention
The objective of the invention is to provide a kind of control system of vehicle hydraulic power air conditioner.It is simple to have structure design, and possesses higher reliability of service.
The present invention realizes with following technical scheme: a kind of control system of vehicle hydraulic power air conditioner, the Hydraulic Pump of vehicle makes by plug-in logical valve and HM Hydraulic Motor and links, the high pressure oil that utilizes Hydraulic Pump to discharge drives HM Hydraulic Motor and makes compressor operating, realizes refrigeration.The oil discharge outlet of the P1 termination Hydraulic Pump of plug-in logical valve, the oil inlet of P2 termination HM Hydraulic Motor, the return opening of T2 termination HM Hydraulic Motor, T1 termination oil return line.2. adopt the plug-in logical valve to control a/c system, its spool is the conical valve cored structure, can improve spool anti-sticking ability and has from clean-up capability.
By the plug-in logical valve Hydraulic Pump of vehicle and HM Hydraulic Motor are linked, make compressor operating, realize refrigeration thereby the high pressure oil that utilizes Hydraulic Pump to discharge drives HM Hydraulic Motor.Owing to adopted the plug-in logical valve to control a/c system, plug-in logical valve spool is the conical valve cored structure, can improve spool anti-sticking ability and has from clean-up capability.Simultaneously, its through-current capability is more much bigger than common guiding valve, avoids causing the system pressure loss too big, makes the hydraulic efficiency pressure system heating.
The invention has the beneficial effects as follows, simple in structure, save the a/c system cost, and effectively improved the reliability that uses a/c system.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Accompanying drawing is a vehicle hydraulic power air-conditioner control system schematic diagram.
Among the figure: 1. Hydraulic Pump, 2. plug-in logical valve, 3. air-conditioning motor, 4. compressor.
The specific embodiment
As shown in drawings, adopt plug-in logical valve 2 that the Hydraulic Pump 1 of vehicle and HM Hydraulic Motor 3 are linked, the oil discharge outlet of the P1 termination Hydraulic Pump 1 of plug-in logical valve 2, the oil inlet of P2 termination HM Hydraulic Motor 3, the return opening of T2 termination HM Hydraulic Motor 3, T1 termination oil return line.By plug-in logical valve 2 Hydraulic Pump 1 of vehicle is linked with HM Hydraulic Motor 3, thereby realized that the high pressure oil that utilizes Hydraulic Pump 1 to discharge drives HM Hydraulic Motor 3 and makes compressor 4 work, realize refrigeration.Why adopting the plug-in logical valve, is because plug-in logical valve spool is the conical valve cored structure, can improve spool anti-sticking ability and has from clean-up capability.Simultaneously, its through-current capability is more much bigger than common guiding valve, avoids causing the system pressure loss too big, makes the hydraulic efficiency pressure system heating.
