How to determine the size of the vacuum diversion tank before the centrifugal pump inlet

You can install a sensor package on your vacuum pump specifically designed to collect and process data to monitor the operating status of your vacuum pump anytime, anywhere. The Busch Vacuum Pump** Monitoring Device (OTTO) can reduce your production costs and downtime while keeping a complete picture of your production. Take your production to the next level with round-the-clock Internet of Things (IoT) remote condition monitoring to optimize your processes.

Vacuum water diversion tank.

Working principle Before use, the vacuum tank must be filled with water, when the water in the tank is sucked out by the water pump, negative pressure (vacuum) is generated in the tank or through the vacuum pump.

Forced to generate negative pressure due to atmospheric pressure.

the role of the cistern.

The water inside enters the vacuum tank through the suction pipe, and the water supply is continuously supplied through the water pump or the centrifugal water pump is started.

Features and scope of use.

The vacuum water diversion tank is used in the down-suction (water low pump high) water pump without self-priming function, and the kg series vacuum water diversion tank has a unique structure and vacuum degree.

high, thus ensuring the high working efficiency of the pump.

The best alternative to vacuum diversion pumps. The volume can be determined by the following formula: l+h) s or v 7(l+h) s

In the formula, l the sum of the vertical height of the suction pipe (the vertical height of the suction pipe is not more than 6 meters) and the horizontal length;

h Vacuum diversion tank height;

s Suction pipe cross-sectional area;

v Total volume of vacuum water diversion tank.

How to use: 1.Connect the suction pipe, vacuum tank, and water pump according to the diagram.

2.Loosen the copper above the tank or connect the vacuum pump here, and open the blind plate of the flange flange above the tank to add clean water to the tank. When there is a steady flow of water out of the copper, tighten the flange blind plate and tighten the copper.

3.After confirming that there is no leakage, the pump can be started and put into normal use.

Vacuum water diversion tank. What came from.

Hello, it is a pleasure to serve you and give you the following answer: the weight of the vacuum pump water mainly depends on the weight of the water and the weight of the vacuum pump. 1. Question:

Due to the large amount of heavy residue of water, when the vacuum pump draws water, the water pressure will be excessive and damaged. 2. Solution: (1) Reduce the weight of water

The weight of the water is reduced by changing the flow rate of the water. (2) Improve the strength of the vacuum pump: improve the strength of the vacuum pump by replacing the vacuum pump, so as to improve the efficiency of the vacuum pump to divert water.

3. Practice steps: (1) Reduce the weight of water: First, determine the flow rate of water, and then adjust the water flow rate appropriately according to the actual situation to reduce the weight of water.

1) The function of the vacuum pump: The function of the vacuum pump is to attract air with a vacuum, so that the water can be led from the low place to the high place to realize the transportation of water. (2) Weight of water:

The weight of the water depends on the flow of the water, the greater the flow, the greater the weight of the water.

Vacuum water tank, vacuum water tank selection.

The choice of the volume size of the vacuum diversion tank should consider the amount of bottom oil and the pumping speed of the vacuum pump. Taking a 50t light fuel tanker as an example, if the bottom oil height is 50mm, the bottom oil volume of each tanker is about 250L; If the bottom oil height is l00mm, the bottom oil volume can reach about 6807L.

When there are many tankers and the oil collection task is tight, if the volume of the vacuum diversion tank is too small, the number of venting times is frequent, which affects the speed of pumping the bottom oil. When receiving oil from oil tankers or oil barges, due to the large oil tank area, the number of bottom oil should be larger.

Vacuum diversion tanks, such as those of the LOM3.

The volume of the vacuum diversion tank should also be adapted to the vacuum pump used. Otherwise, the volume of the vacuum tank is large and the exhaust volume of the vacuum pump is small, and the time for pumping the vacuum water tank to the required vacuum degree is too long, which affects the oil recovery speed.
