FAQ

What are the meanings of the vacuum pump, the front pump and the main pump?

The main pump can be understood as a booster pump, used to improve the vacuum mechanical pump with pumping quantity. As the roots pump, diffusion pumps, molecular pump. These can not use (too much pressure) so the need for mechanical pump drainage, the vacuum chamber is pumped into the rough vacuum, then the main pump starts to work.

Does the reservoir water heater press the booster pump (high marks)?

In addition, the water storage electric water heater has a safety valve is O.7MPa, before buying a booster pump, you can check the water inlet valve spring weakness, see the effect of water, barely even, then use it, do not buy.

What is the main difference between SK water ring vacuum pump and 2BV water ring vacuum pump?

The unified corrosion resistant design of bronze impeller improves the corrosion resistance of the pump, and the stainless steel material is more suitable for more severe applications;

The difference between diaphragm pumps, vacuum pumps and centrifugal pumps

The diaphragm works by changing the size of the diaphragm. When the cup is covered with an eraser and the edge is airtight, then pressing the rubber or pulling the rubber outward will make the pressure in the cup increase or decrease. Use this principle, in the pressure of an hour from a hole suction medium, when the pressure is large, from another hole extrusion medium, so as to achieve the purpose of conveying.

What is the name of the day pump and ground pump? Specific introduction

Day pumpDay pump is called "day pump", the main reason is that it can deliver concrete to a certain height, make up for other concrete pump transportation shortage. Compared with other concrete pumps, the pump has its own boom, and the concrete can be transported without the use of artificial cloth. It is very convenient for use. At present, China's longest boom pump is 101 meters, which means that 101 meters under the floor can be completed with the help of day pump concrete delivery. In addition, the pump is equipped with a chassis, so compared with the ground pump, it can walk independently, moving very convenient, you can quickly move from one site to another location.

What are the starting and stopping procedures for centrifugal pumps?

Before using the centrifugal pump, the operation instructions of the centrifugal pump shall be read carefully and the specific operation procedures shall be understood so as to make proper use of the centrifugal pump products. The first step is the operation of centrifugal pump inlet valve of centrifugal pump centrifugal pump for all open cavity filled with liquid, close the outlet valve, start the motor, the motor speed is normal, can gradually open the outlet valve, to adjust to the desired condition. Pay attention to self suction centrifugal pump starts to open the exhaust valve, outlet valve should be opened quickly in the normal operation of the motor, to prevent air inlet pipe off caused by cavitation phenomenon produces centrifugal pump, centrifugal pump vibration phenomenon leads to noise of the smoke is not on the water.

What is the cause of the damage of pump bearings?

First of all, know your pump model, and what is the bad bearing, in order to accurately judge for you. Because in addition to some common reasons, the structure of different pumps, bearing damage caused by the reasons are different. Otherwise it is fraught with itching shoes.

Variable flow pumps are variable pumps

Variable input speed, the pump out of the flow is variable, it can not be said that it is variable pump.In a word。 A variable pump is a variable displacement pump.
