Product Description
JZJX type rotary vane Roots vacuum pump unit is composed of ZJ Roots pump as the main pump and rotary vane pump as the fore pump in series. The Roots rotary vane vacuum unit uses a rotary vane pump as the backing pump, which overcomes the shortcoming of the low pumping rate under a certain pressure when the rotary vane pump is used, and at the same time retains the Roots pump to work quickly and have a large pumping rate. The advantages. Because of the compact structure, large pumping speed and small footprint, the unit can replace multiple mechanical vacuum pumps, so the Roots pump-rotary vane pump unit is widely used in vacuum smelting, power capacitors, transformer vacuum heat treatment, and vacuum coating equipment. In the pre-pumping, electric vacuum semiconductor and other industries, it is used to extract the gas in the airtight container with low oxygen content, non-explosive, non-corrosive to metal, no chemical reaction with pump oil and no particle dust..Product Photos:Vacuum unit system diagram:

Product Application:
It is widely used in the vacuuming process in the production, installation and maintenance of many electric power equipments, like electric power transformer, capacitor etc., and is also used in the technical process of industrial production, such as vacuum drying, vacuum distillation, vacuum wielding, vacuum coating etc.
It is not suitable for the vacuum process for air and gases containing too much powder, water and oxygen as well as explosive, corrosive, poisonous and chemical substances.
Product Features:
1.The machine adopts special Roots pump and vacuum pump, so the vacuum pumping speed and pressure, are obviously better than any other devices.
2.Working vacuum range and maximum vacuum degree are superior to other products.
3.It is installed with special vacuum gauge for accurate indication.
4.It adopts automatic vacuum relay for automatic control.
5.Stable and reliable operation, low noise, and easy to move.
Instructions for use:
1. Preparations before starting
1. Open the cooling water inlet valve and check whether the cooling water is smooth.
2. Fill the lubricating oil in the cavity of the extended shaft seal and the oil cup, add the lubricating oil in the gear box and the bearing box to the height of 2/3 ~ 3/4 of the diameter of the oil window, and use No. 1 vacuum oil for the lubricating oil.
3. Corresponding measures must be taken when using under the following conditions:
a: When there is dust or particles in the inhaled gas, a dust collector or filter should be installed in front of the inhalation port;
b: If the inhaled gas is corrosive, neutralization measures must be taken;
c: When the suction gas contains water vapor, and the selected backing pump is an oil-sealed mechanical pump, the backing pump should be equipped with a gas ballast device. When there is too much water vapor, a condenser must be installed. Water jet vacuum pump unit
2. Starting procedure:
1. Start the foreline pump.
2. Open the valve on the pre-pumping bypass pipeline of the foreline pump and the valve on the intake pipeline of the Roots vacuum pump.
3. When the pressure in the system reaches the allowable inlet pressure of the Roots vacuum pump, close the valve on the bypass pipeline. Restart the Roots vacuum pump; if the bypass pipeline and valve are not installed, the Roots vacuum pump can be started only after the pressure in the system reaches the allowable inlet pressure of the Roots vacuum pump; if an automatic control device is used, the starting process can be automated .
4. According to the actual situation of the vacuum system, if it is a small sealed system, the roots vacuum pump can be started immediately after starting the fore pump; if it is a larger vacuum system, although the roots vacuum pump with bypass valve has overload protection capacity, but considering the economy, the Roots vacuum pump should be started after the backing pump is pumped to a certain pressure.
3. Attention points in the operation of vacuum unit:
1. The Roots vacuum pump must be used in strict accordance with the technical specifications during operation. Under normal circumstances, the inlet pressure of the Roots vacuum pump is below 133×102Pa, and its maximum inlet pressure should not exceed its allowable maximum inlet pressure. If it exceeds, although ZJP Roots vacuum pump with bypass valve can automatically protect, but this protection is only the overload protection of the motor. Pumps can also fail due to overheating if operated for extended periods of time above the maximum allowable inlet pressure. Water ring roots vacuum pump unit
2. Pay attention to the motor load and the temperature rise of various parts of the pump at any time. Under normal circumstances, the maximum temperature rise of the pump is not allowed to exceed 40°C, and the maximum temperature is not allowed to exceed 80°C.
3. There should be no irregular abnormal vibration during operation.
4. If it is found that the motor is overloaded, the temperature rise is too high, the sound is abnormal, the vibration is too large, etc., it should be stopped immediately to check the cause and eliminate the fault in time.
4. Shutdown procedure of vacuum unit:
1. Close the gas ballast valve of the foreline oil-sealed mechanical pump (if the gas ballast valve is open when the foreline pump is in use).
2. Close the intake valve of the Roots vacuum pump.
3. Stop the pump step by step: stop the roots vacuum pump first, then stop the fore pump, and it is strictly forbidden to make a wrong stop sequence.
4. When stopping the foreline pump, the air inlet of the foreline pump should be bleed immediately.
5. Close the cooling water inlet valve.
6. If you need to stop using the pump for a long time, or to prevent the pump body from freezing and cracking in winter, you must drain all the cooling water in the pump.
