The dual plastic horizontal water jet vacuum unit is a large pumping capacity product extended from the single unit, with a maximum pumping capacity of up to 1200m³/h. It can also be used as a backup for workstations. On the basis of maintaining the characteristics of a single unit, the double unit has added an iron support base (made of No. 8 channel steel), enlarged the water tank, and added butterfly valves to meet more needs of users.

Patent number: Zl2008201895343 Zl.4

Whether the crew is good or not, the machine seal is very important.

1. The space is limited and it needs to be used under working conditions that require a large extraction volume. For example, two vacuum pumps can be turned on in the early stage of material reaction to achieve maximum pumping volume, thereby reducing material reaction time, saving energy, and improving product quality and production capacity; In the later stage of material reaction, when there is less gas production, one vacuum pump can be turned off to achieve energy-saving effect.

2. At important workstations, one vacuum pump of the dual unit can be used as a backup pump. In case one pump is damaged and needs repair, the other can be used directly without affecting production.

Use our company's unique patented machine seal. Better heat dissipation effect and longer service life.

The dual unit basically inherits all the advantages of the single unit SPBZ series unit.

The base of the twin unit adopts national standard No. 8 channel steel and has undergone anti-corrosion treatment.

When installing butterfly valves at the inlet of the dual unit pump, there is no need to empty the water tank when repairing or replacing the pump and accessories. If one is damaged, the other can still be used without delaying production.

The water jet vacuum unit is widely used in chemical, pesticide, pharmaceutical and other enterprises due to its simple structure, easy maintenance, and superior anti-corrosion performance. It should be said that the maintenance cost of a water jet vacuum unit is very low under normal use, but you must have encountered the following situation:deviceAlthough it was being used normally and the water temperature was not too high, suddenly the machine seal burned out, the impeller melted, and the pump body or cover also melted. In a short while, one unitPolypropylene centrifugal pumpThat's it, a thousand or even a few thousand yuan is gone. In this situation, you may blame the employees for not taking good care of the equipment, but it is also very likely that they have been wrongly accused.

In excluding the case of dry grinding of the machine seal, a large part of the reason for this situation may be that the liquid in the pump body vaporizes under certain conditions (there will be local vacuum in the pump body) (or the gas content in the pumped liquid is high), blocking the cooling surface of the machine seal, causing local dry grinding of the machine seal under normal use. In just a few seconds, the machine seal will quickly heat up to 300-400 degrees or even higher at a high speed of 2900 revolutions per minute.

If you have encountered such problems during use, we recommend using our water jet vacuum unit produced by our companyAll models of vacuum units currently produced by our companyAll of them use our company's self-developed patented machine seals, which have been tested by multiple customers and have shown better cooling effects. They can effectively solve this problem and greatly avoid situations where the seal cooling is not in place and the equipment is damaged. Protecting users' investments (with unchanged selling price)

Patent sealing principle: 1. The area of contact between the seal and the liquid increases by 3-5 times. 2. The cooling part of the machine seal extends into the center of the pump body, rather than in the corner of the remote pump body. 3. Localized sharp corners disrupt the formation of bubbles.

Here is one of our clients. Due to the transition period between new and old machine seals at that time, we partially used old machine seals on the equipment, which caused the above-mentioned problem. After free replacement of the patented machine seal, the problem was resolved.
