Q:If the suction pump does not have enough suction range, you need to add a vacuum pump to increase the suction stroke. How do you install the suction pipe of the vacuum pump? Water pump impeller is not closed, it is normal that the vacuum pump is unable to pump suction pipe to a vacuum, is it because the water pump outlet pipe connected to the role of the check valve? But the water pump, outlet pipe, check valve sealing performance can achieve the function of non leakage?: The role of the check valve:"[the water pump impeller is not closed" refers to the pump suction pump before the water without water inlet pipe and water outlet pipe gas should be connected] is a connector, a connector, still can make the level surface, in order to prevent the water flow along the pipe, until it reaches the level of the flush, then increased check valve, or pumping up water will not leak?Vacuum suction principle of self suction pump:Assuming that the pump connected with the water inlet of a sealed container, the container has plenty of water, since the start of a water pump, water is thrown out of the water impeller pump body, water inlet seal vessel due to the extraction of water to form a vacuum cavity, this assumption will be connected to vacuum cavity and exposed to atmospheric conditions of water, water at atmospheric pressure under the effect of entry into the vacuum chamber".....

Q:What kind of motor does the hydraulic pump need?: Calculation of actual oil pump power:First count the flow: Q=dn L / minD displacement / revN RPM / minThen calculate the actual power: N=QP/ (60K) kwQ flow L / minP MPa MPaK total efficiency (usually 0.85)I do not know what the landlord said, 2.5L is the displacement or flow at the end, the concept must not be confused

Q:What does "efficiency" mean in a water pump catalog?: General pump efficiency is 60% ~ 85%. high efficiency of the pump, indicating the same work, the pump consumes the lowest energy, and vice versa

Q:What are the constant pressure pumps?: Chlorine booster pumpThe pressure range of chlorine booster pump is large, and different pump can be used to obtain different pressure area. The input air pressure is adjusted and the output pressure is adjusted accordingly. High pressure can be reached, gas 90Mpa. Wide range of flow, for all types of pumps only 0.1Kg pressure can work smoothly, at this time to obtain the minimum flow, adjust the intake volume can be obtained after a different flow. Easy to control, from simple manual control to fully automatic control, can meet the requirements. Automatic restart, regardless of what causes the pressure drop in the pressure loop, will automatically restart to supplement leakage pressure and maintain constant loop pressure. Safe operation, gas driven, no arc and spark can be used in dangerous situations.

Q:How to install, operate and maintain the pipeline booster pump?: When the pump leaks, check it immediately to prevent leakage. If it leaks with the motor connection, replace the mechanical seal. Check that the power is connected. Is the supply voltage consistent with the operating voltage of the pump?. If the above a and B are normal, please remove the pump, open the pump cover, remove the foreign body in the pump, and then pump the lid on, and then tighten it to normal.No water pump, pump installed in the tap water pipeline, such as tap water level in the pump impeller on the plane (horizontal installation) or center line (vertical) below, you should turn off the power supply, to tap water level rise more than the impeller plane or the center line, connected to the power supply, to avoid mechanical damage (automatic no need to turn off the electric type). When the pump used in pumping wells, please check whether the water inlet pipe leak; pump cavity storage is not enough, should be filled with water, whether the suction process is too high, proper adjustment. Check whether the inlet and outlet diameter is too small or blocked. Automatic type after a period of time, there may be automatic failure phenomenon, mainly stainless steel and other metal products in pipes, long-term precipitation to shut off the power supply after unloading, unscrew the top screw, remove the plastic sheet to be cleaned, and then, according to the original reset, the normal debugging, can be re used.

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:Water pump outlet valve sequence: In order to prevent the generation of water hammer when the pump stops the damage to the rubber head, should be immediately set rubber head pump outlet, the gate valve and the check valve is not a very convincing reason to decide the order of habits in our hospital order rubber head, check valve, gate valve1. Check valve located in front of the pump, I do not know what the significance is too great to think of.2. The actual installation sequence shall be: soft fittings, check valves, gate valves. The pressure gauge is best installed on the water outlet of the pump, but it must be in front of the check valve.Reason: 1) the soft joint is used to reduce vibration. The connection between the pump and the piping system, of course.2) normal work, the gate valve is not operating, and the check valve is frequent action, so the probability of maintenance is larger, when the maintenance of the pump closed, the water outlet valve can be maintained without affecting the normal operation of the system.3) the pressure gauge is installed in the check valve, which can prevent the impact and damage of water hammer on the pressure gauge.

Q: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.

Q:What are the basic technical parameters of the pump?: Two, pump head H head is the unit weight of the liquid pump pumping from the inlet of the pump (pump inlet flange) to the outlet of the pump (pump outlet flange) energy value. Effective energy is a Newtonian liquid through the pump unit is obtained. The N m/N=m, the height of liquid column pumping liquid. Habits referred to as meters. Three, the pump speed is n RPM pump unit time revolutions, represented by the symbol n, the unit is r/min. four, the pump NPSH NPSH NPSH is also called net positive suction head, said main parameters of cavitation performance. Cavitation has been used a h power of five, the power of the pump. And the efficiency of the pump is usually refers to the input power, which is the prime mover on the pump shaft power, it is also known as the shaft power, denoted by P;

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
