1、 WX type oil-freevacuum pumpsummary:

The WX type vacuum pump is an oil-free vacuum pump and is one of the devices used to obtain vacuum. The ultimate vacuum of WX type oil-free vacuum pump is 6 × 10-2Mpa (the vacuum degree of WX type oil-free rotary vane vacuum pump produced and sold by our company can reach 7.5 × 10-2Mpa). It has the advantages of simple structure, easy operation, convenient maintenance, and no environmental pollution. It is a widely used mechanical vacuum pump. Compared with general oil lubricated vacuum pumps, oil-free vacuum pumps have a wider range of applications, including absorption and transportation of various items, as well as material supply equipment for automatic machinery.

2、 Purpose of WX type oil-free vacuum pump series rotary vane vacuum pump:

Oil free vacuum pumps can be specifically applied to the following tasks:
1. Open and load the vacuum suction column on the automatic packaging line.
2. Vacuum suction of paper on printing machinery.
3. Efficient vacuum filling of various liquids into bottles.
4. Vacuum forming of various plastic products.
5. Airtightness test of object surface in vacuum state.
6. Vacuum suction adhesive for labels of cardboard boxes and bottles.
7. Vacuum suction fixation for photographic plate making.
8. Gas analysis guided by pressure difference under vacuum conditions.
9. Supporting the use of various pharmaceutical machinery automation lines.
10. Vacuum suction cup fixtures used for clamping non-magnetic parts during processing.
11. Leak testing of various containers under vacuum conditions.
12. Application in food processing machinery.
13. Zhongxi Pharmaceutical Factory vacuum distillation drying.
14. Vacuum suction in hospital operating rooms.
15. Gas analysis and physical and chemical experiments in universities, research institutes, and industrial and mining laboratories.
16. The matching use of various medical instruments, etc.

3、 The principle of WX type oil-free vacuum pump:

The working principle of WX type oil-free vacuum pump is the same as that of a general volumetric pump, consisting of main components such as stator, rotor, rotor, cylinder body, and motor. The rotor with rotor blades is eccentrically installed in the fixed cylinder. When the rotor rotates at high speed, the four radial sliding rotor blades in the rotor slot divide the pump chamber into four working chambers. Due to centrifugal force, the rotor blades are tightly attached to the cylinder wall, separating the stator inlet and outlet, and running repeatedly to change the volume. The inhaled gas is discharged from the exhaust port, thus achieving the purpose of pumping.

4、 Characteristics of WX type oil-free vacuum pump:

1. Due to the absence of oil vapor in the WX type oil-free vacuum pump, the working environment and processed products will not be contaminated by oil when in use, making it the most ideal vacuum equipment for use in industries that strictly require oil-free vapor.
2. Compared to vacuum pumps that do not require oil lubrication, oil-free vacuum pumps can greatly reduce regular maintenance and upkeep, without the inconvenience and trouble caused by the lack of vacuum oil for repairs.
3 The WX type oil-free vacuum pump is directly connected to a motor, with a compact structure, light weight, and smaller external dimensions than other types of pumps.
4 The WX type oil-free vacuum pump uses multiple blades for high-speed rotation, avoiding pulse fluctuations in the suction and exhaust processes.
5 The WX type oil-free vacuum pump can operate continuously in open air.

7、 Installation and use of WX type oil-free vacuum pump:

1. It should have sufficient and good ventilation conditions and an ambient temperature below 40 ℃.
2. A clean place without dust and dirt.
3. Liquids such as water and oil will fall onto the pump.
4. Not directly exposed to sunlight.
5. There is sufficient surrounding space to facilitate the inspection, maintenance, and disassembly of the pump.
6. The WX type oil-free vacuum pump must be installed on a flat surface.
7. It is best to install the WX type oil-free vacuum pump on a hard foundation similar to concrete. If conditions permit, the pump can also be securely mounted on a steel or wooden frame.
8. It is necessary to ensure that the WX type oil-free vacuum pump does not vibrate due to an unstable foundation.
9. The connecting pipeline with WX type oil-free vacuum pump should not be too long or smaller than the pump inlet diameter, which will affect the pumping speed. Also, pay attention to checking whether there is any air leakage in the vacuum connecting pipeline.
10. When connecting wires, attention should be paid to the wiring requirements specified on the motor nameplate. Three phase electric pumps should pay attention to the direction of motor rotation, which should be consistent with the direction indicated by the arrow on the pump.
11. After prolonged continuous operation, there will be a significant increase in pump temperature, which is normal and there is no need to worry about the lifespan of the WX oil-free vacuum pump.
