The overall application of vacuum pump unit, through advanced equipment processing, from the basic production capacity to speed up the quality improvement of the unit products, which is very in place for the effective play of the entire product application ability, so we should improve the ability of its advantages in all aspects, strengthen the development of product application reliability, and promote the application ability of various aspects with faster product performance In order to speed up the development process of the unit. It can be used to extract a large amount of condensable steam, especially when the ability of removing condensable steam is not enough, or the solvent used can deteriorate the pump oil and affect the performance, or the vacuum system does not allow oil pollution. If equipped with explosion-proof motor and electrical appliances and comply with the corresponding safety rules, flammable and explosive gases can be removed.

1、 Cause: generally, when using the vacuum pump unit, the valve opening is large and the vacuum degree is high, resulting in water or a large amount of water vapor being pumped into the buffer tank, so as to enter the water.

2、 Solution: open the outlet valve at the bottom of buffer tank of vacuum pump unit to drain water. Generally, a small part of water should be left in the buffer tank of vacuum pump unit

As the bottom sealing test of the buffer tank. The knowledge of vacuum pump unit I believe you have some understanding, to have a better use of it, for its water filling method should understand.

1. Manual water filling method: for small pumping stations with inlet pipe diameter less than 300 mm, a bottom valve is usually set at the inlet of the inlet pipe. Generally, manual water filling method is adopted, that is, water is filled from the special water filling vent on the upper part of the vacuum pump unit shell (or an inverted common bottle with the bottle bottom removed). For small pumping stations with inlet pipe diameter less than 300 mm, a bottom valve is usually set at the inlet of the inlet pipe, and water can be filled into the pump from the outlet pipe orifice of the vacuum pump unit (the pump station with short outlet pipeline). Because there is no need to buy other water filling equipment, this method is more common in small pumping stations in rural areas.
