5.FAQ
·What is the delivery time?

- Q:What is the dry running protector of screw pump? What's the principle and function? Thank you
- When the temperature reaches a certain value, the signal is transmitted to the electric control box through a dry running protector, and the electric control box is used to stop the screw pump so as to protect the screw pump.
- Q:Is the flow meter in front of the pump or after the pump?
- Agree upstairs. Pump should be straight before the paragraph, 15 times the nominal length of the caliber.
- Q:How can I buy a pump?
- 2, must meet the characteristics of the media requirementsFor the delivery of flammable, explosive, toxic or valuable medium pump, requiring reliable sealing shaft or the use of non leakage pump, such as magnetic drive pumps (without shaft seal, using isolated magnetic indirect drive).For the transmission of corrosive medium pumps, convection components are required to use corrosion-resistant materials, such as fluorine plastic corrosion resistant pump.For conveying pumps containing solid particles, wear resistance materials shall be adopted in convection parts, and clean liquid shall be used for shaft seal when necessary.
- Q:Why should the pump be closed when the centrifugal pump is started?
- Therefore to close the outlet valve, the pump during starting output water, the minimum pump power, when the pump reaches the rated speed, slowly open the outlet valve, gradually increase the flow of water, the motor current is gradually increased to the rated current.
- Q:What is pump suction work?
- In the ventilation process, pump suction is formed. The ventilation process is the whole process from opening to closing of the exhaust port. Pump Qigong refers to the cylinder gas on the piston in the forced exhaust stroke and suction stroke done by the work
- Q:The function of centrifugal pump
- 4, bearings are set on the pump shaft supporting the pump shaft components, there are two kinds of rolling bearings and sliding bearings. Rolling bearings use butter as a lubricant, refueling should be appropriate, generally 2/3 ~ 3/4 of the volume is too much, will heat, too little, there is noise and fever! The plain bearings are made of transparent oil as a lubricant and fill up to the oil level. Too much oil will leak out along the pump shaft and float *, too little, the bearings will overheat and burn out, causing accidents! In the pump running process, bearing temperature is highest in 85 degrees, generally run at about 60 degrees, if higher, will find the reason (whether there is impurities, whether the oil is black, whether water) and timely processing!
- Q:Centrifugal pump flow, why can be adjusted through the outlet valve? Can the flow of the reciprocating pump be adjusted in the same way?. Why
- Centrifugal pump, and is a very common method of centrifugal pump, flow with the head (or pressure) increases, off a small valve resistance increases, the pump head should be increased, then the flow decreased, whereas open valve flow increase
- Q:What is double hydraulic pump?
- [double hydraulic pump] the same drive shaft drives the rotation of two pumps, which are connected together and driven by an electric motor. The suction port of the pump is common, and the oil pressure port is separated from each other. Pump output of two shares of flow can be used alone, can also be used in parallel. This pump, a pump can play the function of two pumps. For example, there are two pumps on the loader, a pump acting as the work, a pump acting as the steering, and the double linked pump can replace the functions of the two pumps. It works by coupling the two pumps at the same time.
- Q:Operating procedures for measuring pumps
- First, preparation and inspection before starting1. Check to make sure that the drain line is equipped with a safety valve with the correct set pressure.2. Check the screws for the liquid end parts.
- Q:What kind of motor does the hydraulic pump need?
- The motor should be determined according to the work environment, such as 220V.12V.24V.72V or 380V, and then the power.Calculation of actual oil pump power:
