◊ Working principle
The systems are AUTOMATIC PRESSURIZATION UNITS utilizing on pumps such as SGJ, TCP, JET, TDP, QB. They are supplied completely with a tank, a pressure switch and a pressure gauge( or electronic switch). The systems can provide sufficient water pressure for modern domestic appliances to ensure enough water supply.

Q:What is the liquid pump? What are their categories? What are their strengths and weaknesses?
The pump is constructed by connecting large diameter gas piston with small diameter hydraulic piston. The two piston area ratio produces a pressure ratio, and the maximum output pressure can be calculated by the pressure ratio. High pressure ratio produces high outlet pressure. You can set the outlet pressure through a simple gas pressure reducing valve. Pressure ratio * gas drive pressure = output pressure.
Q:What are the main performance parameters of hydraulic pumps?
Displacement and flowDisplacement refers to the pump (or motor) every turn a week, by the size of the sealing chamber geometry variable discharge (or enter) the volume of liquid, commonly used unit is ml/r (ml / rev). Displacement can be changed as a variable pump (or variable motor), and the displacement can not be changed into a quantitative pump (or a quantitative motor).Actual flow is the amount of flow at the outlet (or inlet) when the pump (or motor) is operating. As the pump itself leaks, the actual flow is less than the theoretical flow. As the motor itself has an internal leakage, to achieve the specified speed, in order to compensate the leakage, the actual flow of input must be greater than the theoretical flow.
Q:What is the pumping property of concrete?
Pumpable concrete slump is generally greater than 160mm, the mortar content is too low, the maximum aggregate size of not more than 1/3 of the diameter of the pump pipe, sending process segregation, plugging in the pump.
Q:What is the relationship between the minimum suction vacuum of a pump and the required cavitation?
When the pump is working, the liquid at the inlet of the impeller, due to a certain vacuum pressure will produce steam, the vaporization of the bubble in liquid particles under the impact of movement, the impeller and other metal surface erosion, thereby damaging the impeller and other metal
Q:Direct connection pump What is straight pump and non direct pump? What's the difference in structure?
What is straight pump and non direct pump? Direct coupled pump shaft and the motor shaft is directly coupled with the coupling and non direct coupled pump: pump shaft and motor shaft through the belt pulley, V-belt connection or other forms of transmission. What is the difference in the structure: the direct coupled pump has the advantages of compact structure, simple installation, but the relatively small power; non direct coupled pump: pump and motor is independent, the two transfer torque through the belt, the structure is relatively large, complex installation, general power is relatively large.
Q:Is the diaphragm pump and the drain pump one?
First of all, there's something wrong with your concept.Diaphragm pump is in accordance with the way the pump classification, drain pump is in accordance with the use of pumps classification.
Q:5 floor water pressure is too low, what kind of water pump is better?
Installed pump flow, lift did not meet the requirements, this will need to re type selection, calculation;
Q:Is vane pump good or gear pump good?
The main working parts of vane pump is provided with a plurality of sliding vane rotor, when the rotor rotates, the eccentric configuration of stator cavity contour or rotor, blade sliding slot in leaves due to volume changes, resulting in the suction effect. The similarities are: 1, rotary type positive displacement pump has self-priming ability, but are not allowed to do; 2, with continuous flow pulsation, but also have flow and pressure; 3, the theory of flow is determined by the working parts of the size and speed, has nothing to do with discharge pressure; 4, rated discharge size, pressure and working parts mainly depends on the pump speed is independent of the sealing parts and bearing capacity; differences: 1) gear pump structure is more simple, reliable, low price; vane pump has complicated structure and high manufacturing precision parts, the blade is easy to get stuck, more sensitive to the oil clean degree and viscosity.
Q:Why is the sewage pump device coupler?
2. automatic coupling device of the sewage pump coupling device has compact structure and small occupation area. Because the sewage pump is submerged, it can be installed directly in the sewage tank, and no special pump room is needed to install the pump and pump. It can save a lot of land and infrastructure costs.
Q:What is the difference between centrifugal pump and positive displacement pump?
The centrifugal pump is to rely on high-speed rotation of the impeller to do work on the fluid. These two types of pumps are also the most widely used.
