Product Description

Single-stage multi-rotary vane series vacuum pump

 

Product Description

             The XD single-stage multi-rotary vane series vacuum pump developed by our company adopts foreign advanced technology, high-tech materials and advanced technology. It has compact structure, beautiful appearance, high vacuum degree, wide application range, long service life, easy maintenance, can be vacuumed and compressed air. It is mainly used for large, medium and small feces suction, pollution suction special vehicles and industrial and mining enterprises and schools.
 

structure

XD single-stage multi-rotary vane series vacuum pump is mainly composed of pump body, rotor, front and rear end cover, rotary plate, bearing, coupling and other parts, the rotor center is placed in the center of the pump body.


Working principle

 

When the eccentric rotor rotates, the rotating disc slides close to the inner wall of the pump under the action of centrifugal force,
the volume of the suction studio gradually increases,
and the pumped gas is sucked into it until the rotating disc is turned to the end of the suction,
and the inhaled gas is isolated.
The rotor continues to rotate, the isolated gas is gradually compressed, the pressure is increased,
and when the pressure exceeds the pressure of the exhaust port,
the gas is discharged from the pump.
This cycle is repeated to remove the air from the container to form a vacuum.


Installation and debugging

1. Install the pump on the inside of the automobile girder with a suitable shelf and Angle iron.
The position of the pump, high and low, left and right, front and back,
is determined by the shaft line of the force takeer drive shaft,
and is as close to the force takeer and the girder as possible without interfering with the components of the automobile girder.
The connection inclination Angle between the pump shaft and the drive shaft of the force extractor shall not be greater than 7 ° C.

2. The suction pipe system is strictly prohibited from leaking,
otherwise the vacuum degree will be affected,
and the exhaust pipe should not leak to avoid vacuum discharge,
pollution of the environment and waste of energy.

3. The installation position of the oil and gas separator should be higher than the oil inlet joint of the vacuum pump.
Cold ground pressure or cold season to change the antifreeze lubricating oil to ensure that the oil circuit is smooth,
the first use of 50 hours to replace the new lubricating oil, and regular cleaning.

4, because this pump is oil-sealed pump,
normal operation must keep enough N32 mechanical oil, northeast,
northwest winter cold season should use 32 refrigerated oil, oil seal gap and lubrication,
but the oil in the pump will also be taken out of the pump when the exhaust,
so it must be installed outside the exhaust port oil separator,
oil recovery and pump recycling, gas discharged into the atmosphere.
Make the pump run smoothly to achieve the purpose of no pollution and energy saving.

 

5.Vacuum pumps with pumping rate greater than 100l/s
are prone to oil injection after 5 minutes of working time due to high pumping speed,
which is a normal phenomenon.

 

 

Maintenance

1.should often check the amount of oil, oil quality is normal,
if it has been emulsified must be replaced with new oil.

2. The water separated from the water gas separator is stored in it,
and it should be discharged regularly, otherwise it will affect the exhaust.

 

Fault and solution

When the pump failure affects the use, you can refer to the following solutions or consult the manufacturer to solve:
 

breakdown	reason	solution
Insufficient vacuum pump	1. The oil inlet pipeline is blocked or leaky 2. Air leakage in the intake pipe 3, the triangle belt is too loose, the pump speed is not enough 4, spinning disc wear or damage 5, skeleton oil seal wear 6, measuring instrument distortion, indicating error 7, four-way valve seals wear, gas channeling	1. Sort out the oil supply pipeline 2. Tighten the intake pipe 3, adjust the belt tightness 4. Replace the damaged rotary sheet 5. Replace the skeleton oil seal 6. Replace the measuring instrument 7. Replace the damaged seals
Excessive pump temperature	1. The oil inlet hole is blocked or the gas supply is insufficient 2, there are foreign bodies into the pump 3, bearing damage	1. The oil inlet hole is blocked or the gas supply is insufficient 2, there are foreign bodies into the pump 3, bearing damage
Pump outlet injection	1. Too much gas 2, continuous working time produces high temperature	1. Drain oil to oil level 2, shut down cooling, high-power pump a small amount of oil injection is normal
Starting difficulty	1. There is corrosion in the pump cavity 2. The spinning disc has been damaged 3, motor or line fault 4. The air outlet is closed or blocked	1, clean pump cavity rust 2. Replace the rotary sheet 3, check or replace the motor or line 4. Open the air outlet or clean up foreign bodies in the air outlet
Abnormal operation and noise	1. The triangle belt is too loose 2. The screw is loose 3. Foreign matter enters the pump cavity 4, spinning disc break	1. Adjust the position of the pulley 2. Tighten the screws 3, clean the pump chamber 4. Replace the spinning disc
