Abstract
The invention provides a gas pressure control device of a locomotive machinery room and a method, wherein a pressure sensor is arranged in the machinery room; a detected gas pressure signal is transmitted to a controller; machinery room door opening and closing contacts are arranged on a door handle; machinery room door opening and closing signals are transmitted to the controller; the controller controls the action of a gas pressure adjustment and execution mechanism according to the signals; critical values Q1 and Q2 of gas pressure adjustment are set like that Q1 is less than Q2; a real-time gas pressure value P of the machinery room and a machinery room door signal are detected; when P reaches Q2, the gas pressure adjustment and execution mechanism is controlled to open an exhaust port; when P is less than Q1, the exhaust port is closed; when the machinery room door signal is in the 'Opening' state, the gas pressure adjustment and execution mechanism is controlled to open the exhaust port; and after 30 seconds, the exhaust port is closed. The opening of the gas pressure adjustment device can be automatically controlled; and therefore, the machinery room equipment is guaranteed to have good ventilation; the equipment fault rate is decreased; and meanwhile, drivers and conductors open a machinery room door conveniently to enter the machinery room for routing inspection.
Description
Technical field
The invention belongs to the railway locomotive technical field, relate in particular to Pneumatic controller and method between a kind of locomotive machinery.
Background technology
Be to guarantee equipment air-conditioning requirement between railway locomotive machinery, the car body ventilating set in car, for preventing in the car that pressure is excessive between machinery, is provided with the mechanical pressure balancing device in usually between machinery by the outer air draught after-blow of car., because closing naturally, when positive pressure reaches certain numerical value between machinery, exhaust outlet can be backed down to the inside, to reach the purpose of decompression Action of Gravity Field at normal pressure downforce liberation port (exhaust outlet).Because existing machinery air exhausting device depended on pressure release board self gravitation is closed, be subject to the restriction of the factors such as installation site, device unlatching sensitivity, the faults itself rate is higher, and action effect is not good.In the practical application, when blast between machinery increases, if exhaust outlet can not normally be opened or opening angle out of reach decompression requirement, can cause temperature between machinery, hypertonia, cause equipment accelerated weathering between machinery, the driver and conductor is difficult to normally open door between machinery.In addition, if exhaust outlet can not be closed for a long time, then can't set up interior pressure-fired between machinery, can cause interior draft equipment improper ventilation between machinery, dust increases between machinery.
Summary of the invention
Purpose of the present invention overcomes the deficiency of above-mentioned prior art exactly, and Pneumatic controller and method between a kind of safe and reliable locomotive machinery is provided.
The object of the present invention is achieved like this: Pneumatic controller between a kind of locomotive machinery, it is characterized in that being formed by door switch contact, controller and air pressure adjustment actuating unit between pressure sensor, machinery, in pressure sensor is arranged between machinery, institute is surveyed air pressure signal pass to controller, the door switch contact is arranged on the grip handle between machinery, door switch signal between machinery is passed to controller, and controller is according to the action of these signal control air pressure adjustment actuating units.
The control method of Pneumatic controller between a kind of above-mentioned locomotive machinery is characterized in that adopting the following step:
A. set air pressure adjustment critical value Q1＜Q2;
B. detect between machinery in real time gate signal between atmospheric pressure value P and machinery;
C. control air pressure adjustment actuating unit is opened exhausr port when P reaches Q2, to P exhaust close during less than Q1;
D. gate signal is opened exhausr port for " opening " time control air pressure adjustment actuating unit between machinery, closes to 30 seconds rear exhaust port.
In order to realize better purpose of the present invention, set described air pressure adjustment critical value Q1=90Pa, Q2=50Pa.
Adopt the solution of the present invention, but equipment well-ventilated between machinery is guaranteed in the unlatching of automatic control pneumatic control apparatus, reduce equipment failure rate, be convenient to simultaneously the driver and conductor and open between machinery door and enter between machinery and patrol and examine.
