VACUUM-PRESSURE PUMP 16 PARTS

YT-0673

Product description

The vacuum pump is a многофункциональный device used for diagnostics of systems in cars and technology, the operation of which is based on pressure or underpressure.

It is equipped with accessories that can be used in almost any engine or system.

диапазон измерения: -1-0 бар.

Purpose / Application

With the help of the pump, you can carry out diagnostics, включая of the following systems and arrangements:

Computerized engine control devices:

- барометрический датчик давления (BARO)

- ПВХ системы

- exhaust Gas recirculation (EGR)

- thick film Pressure sensors (MAP)

Ignition control devices:

- Vacuum ignition advance

- delay valve: SDV, RCV

Тормозная система:

- классический brakes

- ABS brakes

- Air brakes

- Brake cables

- Brake servo

other systems:

- Air conditioning

- круиз-контроль

- fuel tank and fuel system

- vacuum door closing system

Usage method

Diagnostics of the exhaust Gas recirculation (EGR) system

The EGR valve is an example of a vacuum actuated valve.

In the absence of vacuum, The valve is closed and the exhaust gases not come out of the valve.

когда вакуум применяется к клапану, он открывает возможность выдыхания газа.

Diagnostics of thick film Pressure sensors (MAP)

• Assemble the pump and водохранилища system as in the case of bleeding the brake calipers, then connect to the vacuum connection of the sensor.

• Press The Pump lever until The needle shows -0.5 bar. Останови насос и следи за указателем, он должен быть статическим. Если указатель движется, датчик карты дефективен.

• During operation, MAP sensor посылает сигналы обратной связи на компьютер управления.

the signal frequency is between 85 Hz and 160 Hz depending on the Vacuum level.

чтобы измерить частоту, а счетчик частоты необходим, он должен быть подключен в соответствии с инструкциями датчика и счетчика.

Bleeding the brake calipers.

• Make sure that the brake Expansion tank is filled with fluid to the nominal volume.

• Carry out the bleeding in the following sequence:

- главный цилиндр, if equipped with a bleed valve

- the brake calipers in sequence from the one ближе to the master cylinder to the furthest one

• Connect the short hose to the connection on The underside of the pump's Tank cover.

• Close the Pump reservoir with the lid.

• Connect long hoses to the cover connections. Соедините конец одного из длинных шлангов к насосу, а другой конец-к кровоточащему клапану (calipers) тормозного суппорта. Use an adapter if necessary.

• Press The Pump lever 10-15 times to create a vacuum in the Pump reservoir.

• Open the air vent valve 1/4-1/2 turn so that the Pump reservoir is about 5 cm full with fluid. Плотно вентилируемый клапан.

• Disconnect The Pump hose from the bleed valve, The clamp bleeding процедура is complete.

• Before repeating the bleeding процедуру in the next caliper, empty the pump водохранилища from the brake fluid and top up the brake fluid level in the brake system to the nominal level.
