◊ Application

This series of pumps are elementary equipment for pumping air from sealed vessels. It can be used alone, also can be used as the forepump, process pump or titanium pump of booster pump, oil diffusion pump, and molecular pump. It is applicable to vacuum coating, vacuum heat treatment, vacuum smelting, vacuum tube, bulb, refrigeration, chemicals, packing, forming, health and medical appliances, laboratory, vacuum drying machines and vacuum filtering.

◊ Technical data

Q: What is a water pump coupling device?: Advantages of water pump coupling device:1. automatic coupling device, easy installation and maintenance. In the absence of automatic coupling device, fixed installation, such as water pump failure, maintenance personnel need to unscrew screws, lifting pumps for maintenance, or with other small pumps pumping water perfect maintenance,If the water is dirty, it is difficult for people to get down, when the inspection and repair encountered great difficulties. But it is equipped with GAK submersible sewage pumpAfter the automatic coupling device needs lifting, the person can directly lift the water pump without the need to screw the screw into the waterAfter graduation, down the guide rail, you can realize the sealing of water pump and pipeline, so as to make the pump run normally. Small sewage pumps are freeInstallation, large sewage pumps are generally equipped with automatic coupling device, automatic installation, installation and maintenance is very convenient.

Q: What are the important parameters of the pump?: Mass flow is expressed in Qm units: t/h, kg/s, etc.The relation between mass flow and volume flow is:Qm= P QIn the p - type liquid density (kg/m3, t/m3), room temperature water P =1000kg/m3.Lift H

Q: The water tank of the fish tank does not air out and only has the water outlet: The water pump is cut off, the intake pipe is drawn out, and the water in the air pipe is blown out, then the water pump is put on the surface of the water, and the air inlet pipe is inserted on the surface of the water pipe, and then the water pump is put back into the water, and the water pump is electrified. Try again several times at a time. It should be effective.

Q: Pump unloading in hydraulic transmission,: Unloading is pumping oil directly back to the tank, the pressure is very low, energy saving

Q: Fire control center manually start the fire pump directly, multi line control, called straight up line NHKVV-7*1.5, my understanding is: straight line from fire control center: Multi line linkage NHBVR-4*1.5 is a positive pressure blower and smoke exhaust machine fire fighting equipment

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?: (three) infusion limited number of pills produced after the dose of obstruction by infusion pump and specification of the matching test, will reach acceptable when the storage pressure of the pressure to determine the alarm blocking. Thus, some have restrictions on the infusion tube blocked after the maximum dose pill may have blocked the trigger before the alarm.

Q: How high can the pneumatic diaphragm pump be?: Pump made of polyvinylidene fluoride (PVDF) material two, the series of pneumatic diaphragm pump belongs to the fluorine plastic pneumatic diaphragm pump is also known as the corrosion products of pneumatic diaphragm pump, diaphragm liquid contact using PTFE material, using PVDF material produced by pneumatic diaphragm pump is mainly used in corrosive the pH, mainly used for chemical liquid conveying multiple solvent, corrosion resistance effect is very good. The series of fluorine plastic pneumatic diaphragm pump in high temperature less than 93.3 degrees.POM pump material also has good resistance to solvent and abrasion resistance, low friction resistance, moisture absorption is also low, the highest temperature of such pumps within 65.5 degreesPolytetrafluoroethylene (PTFE) membrane corrosion resistance is very good, in addition to liquid metal lithium, potassium fluoride, sodium fluoride, three chlorine, three fluoride high temperature oxygen, high flow rate, almost all of the chemical liquid transport (including concentrated nitric acid and aqua regia), PTFE material the maximum temperature to 176.6 degrees. However, for the diaphragm pump product as the diaphragm moves back and forth in work, we suggest that at a temperature of 120 degrees, the prerequisite is the pump body pump must be made of metal material and plastic material. The pump is the pump of PVDF material temperature is highest in less than 93.3 degrees.

Q: Roots pump and dry pumpRecently involved in the work of the vacuum pump, don't understand this, is a ads602 vacuum pump, composed of roots pump and dry pump, is pre pumped to the 500mtorr equipment, the main pumping vacuum continues to 10mtorr, where the roots pump and dry pumps must be used? What role they play respectively. The so-called dry pump? Is refers to one kind of the pump, the pump is many dry pump? Also do not understand how the work of automatic switching system for pre pumping, the main pump, pump work alone did not connect system ah (of course there are even a butterfly) teach?: Here the roots pump and dry pump must be used, because the roots pump is not used alone, and must be a stage vacuum pump (pre vacuum pump can be dry pump, water ring vacuum pump and rotary vane vacuum pump can be, you here with dry pump series)

Q: Pneumatic diaphragm pump compressed air pressure is 4 kg, the discharge pressure is how big?: Pigment pressure is less than 0.4mpa,About 0.3. Go up.As the pump diaphragm is in the middle of a connecting rod, equivalent to the cylinder cavity, the pressure will be reduced; and because of the loss of pigment tube pressure will be reduced.

Q: When the water pump is started, why should it start when the outlet valve is closed? Thank you: When the valve is closed, the flow of the pump is close to zero, the power of the pump is very small, which reduces the load that the motor starts to bear and has a protective effect on the motor. Therefore, the valve closed to start the pump.
