(3). How long is your warranty?
Unless otherwise expressly authorized in writing, by specifying a longer period or different conditions, CNBM states that, for a period of twelve (12) months from delivery date, all Products supplied are free from defects in materials and workmanship, and conform to the applicable specifications. Either the delivery documentation or the invoice must be provided to prove delivery date. In absence of such documents, the production date appearing on the product label may suffice.
(4) Are your pumps cheaper than those of your competitors?
CNBM aims to give its customers the highest standards of quality and service and delivery times, all at a reasonable price.
(5) Do you have self-priming pumps?
Yes, our product portfolio also includes two ranges of self-priming pumps: self-priming electric pumps and self-priming side channel pumps.
(6) Is it really necessary to fit a bleed valve for the boxes?
It is always best to have a bleed valve as the gas produced by the fermenting sewage is potentially hazardous.
- Q: Piston filling and peristaltic pump filling which precision is high?
- First of all, we should know the working principle of each, and analyze the accuracy from the principle, this problem is very important. Piston filling, such as the injection of drugs that we have been ill, the accuracy of the piston pump depends on the accuracy of the motor and the area of the unit cross section
- Q: What are the general water pump failure, how to repair?
- (2) in contact with the water pump inlet of the horizontal application of reverse flow direction, fell more than 0.5% slope, connect one end of the highest import pumps, do not completely level. If the upward tilt, the intake pipe will retain air, reducing the water pipes and pumps in the vacuum, water absorption.
- Q: Rules for operation of centrifugal pumps
- Working principle and process flowWorking principle: when the drive motor with high-speed rotating impeller, full of fluid in the pump body under the action of centrifugal force, was thrown from the impeller center to the outer edge of the impeller, in this process, the fluid energy, improve the pressure can, at the same time also increases the energy flow rate increase. The liquid from entering the pump impeller shell, the liquid flow gradually widened, the liquid velocity decreased gradually, which will be part of the kinetic energy into pressure energy, which further improves the static pressure of liquid, and liquid with high pressure in pressure pipeline. When the liquid from the leaves out when the impeller center creates pressure and low pressure than the out plane is big, under pressure drive, liquid is continuously from the center of the impeller suction, with the pressure of continuous discharge.
- 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 pumping property of concrete?
- Under a certain pump pressure, the farther or higher the concrete can deliver, the lower the probability of clogging, the better the concrete pumping performance.
- Q: Is the flow meter in front of the pump or after the pump?
- After the flowmeter is placed in the pump, it is better to add a pressure tank or a buffer tank, so that the flow meter will work better
- Q: What are the problems that should be paid attention to when using vacuum pumps?
- What are the problems that should be paid attention to when using vacuum pumps?
- Q: Because the water pressure of the booster pump is not enough, it can not work automatically. It can only be operated by hand. It is inconvenient to use.
- The worst case is that the pump is not automatic when it leaves the factory, and no one can say whose product is 100%.But there may be automatic control of this piece, not debugging (this depends on the specific product manual or manufacturer)
- Q: What is the series of pumps? What is the difference between a unipolar and a multilevel? What is the meaning of each "first class"?
- A single-stage pump is a pump with only one impeller. 2, a multistage pump is a pump with two or more impellers. The multistage pump can increase the pressure and lift the head higher. Level 1 means a booster impeller.
- Q: Why adjust the centrifugal pump outlet valve can adjust the flow? What are the advantages and disadvantages of this method? Is there any other way to regulate the flow of the pump?
- The use of frequency converter to adjust the speed of the motor can also adjust the flow, the advantage is to save electricity.
