Q: How can the submersible pump level meter be connected?: The company actively introduce international advanced production equipment and production technology, with its strong technical force, perfect equipment conditions and rich manufacturing practice, constantly development and improvement of pump products, according to the needs of users of innovative products, stable performance, excellent quality, many products export part countries and regions

Q: Rotary vacuum pump does not meet the requirements of vacuum, what are the reasons?: (1) the disk, stator or bushing is worn and shall be inspected, trimmed or replaced with a rotary vane vacuum pump.(2) the pump temperature is too high, which not only reduces the viscosity of the oil, increases the saturated vapor pressure, but also may cause cracking of the pump oil. Ventilation, cooling and environmental temperature should be improved. If the exhaust gas temperature is too high, should be cooled before entering the pump, the environment temperature is high, should try to use a better high speed vacuum pump oil or 3# diffusion pump oil. (10) because of the deformation, wear or movement of the parts, the maximum opening height of the check head can be reduced or even unable to be opened, the intake of oil is too little, and the vacuum degree of the rotary vane vacuum pump is reduced, and should be adjusted as shown in the assembly section. Open high, more oil, but open too high, check valve in some places on the stop, it will not automatically drop, lost to prevent oil returns. The commonly used rotary vane vacuum pumps mainly include double stage rotary vane vacuum pump and single-stage rotary vane vacuum pump

Q: What is the minimum continuous flow of a pump?: Quality solutionsMinimum flow of pump, minimum continuous flow of pumpIn order to ensure the proper use of the pump and the normal operation of the pump manufacturer will indicate the minimum pump in the sample of the continuous operation flow, the correct selection or use to warn or instruct users. According to the provisions of the API standard, the minimum continuous flow into the minimum continuous stable flow and continuous flow. Most small thermal limit(1) the minimum continuous stable flow.API standard specifies the minimum continuous stable flow refers to the vibration limit does not exceed the standard set by the pump can work normally. The minimum flow pump at small flow rate, there will be noise and vibration increase, API of this provision is to ensure that the service life of the pump, avoid due to improper operation of the pump caused by the adverse effects.

Q: What is the pump, how to classify, mainly used in where?: Classification of pumpsAccording to the principle of division:1. displacement pumpDepending on the movement of the work parts, the volume of the work increases periodically and reduces the suction and discharge of the liquid, and the pressure of the liquid increases directly by the extrusion of the working partsAccording to the different movement of moving parts, it can be divided into two types: reciprocating pump and rotary pumpAccording to the structure of the moving parts are different: piston pump and piston pump; there are gear pumps, screw pumps, vane pumps and water ring pump

Q: What does electromechanical vector pump mean?: It is a close set of mechanical and microelectronic technology. It adopts dual control center mode to control, and has a new water pump with logic control center and IPC control center.

Q: Brief description of centrifugal pump on / off operation: Two, centrifugal pump start(1) the pump entrance valve fully open, start motor, outlet valve fully closed, fully check operation of pump.(2) when the pump outlet pressure is higher than the operation pressure, the outlet valve is gradually opened to control the flow and pressure of the pump.(3) check whether the motor current is within the rated value, such as the pump in the rated flow operation, and the motor overload should stop the pump inspection.

Q: Bolus dosage of infusion pumpWhat is the purpose of the pill dose control in the special safety standard for infusion pumps? If the risk is not properly controlled, what is the degree of risk? And how can the open infusion pump be used in this regard?: (1) the pellet dose in the safety standard of the infusion pump refers to the amount of liquid that is transported to the patient in a short period of time(two) pill dose limit is mainly to control the risk of accidental pill dosage. Especially after the mandatory requirements of pipe blockage in the elastic pipe storage liquid limit amount of agglomeration and the limitation of these methods to release pill dose.

Q: What is the difference between the ground pump and the pump in the commercial concrete?: Day pump: the pump and pipe will be placed in a position on the site, the pipe in the air like the crane arm

Q: What is the distance between the pump and the wall?: What do you mean by that? If your pump is parallel to the wall! Then, the wall of the pump near the wall is usually 500mm. This is an empirical data, considering the import pipe length, pump maintenance and motor heat dissipation and other aspects of the situation to determine. Dozens of pumps installed in our company are placed in this size! Hope to be of help to you.

Q: How to calculate the motor power of metering pump?: The total mechanical power and hydraulic power, divided by the overall efficiency of pump, and the pump head and the utilization rate of pump mechanical efficiency, and then multiplied by 1.1 times (API675), you can get a metering pump motor need more power.
