Q: What is a gear pump for?: Gear oil pump is through a pair of parameters and the same structure of the involute gear of each other rolling meshing, the tank of low pressure oil to work can do the important parts of high pressure oil. A power unit that converts the mechanical energy of an engine into hydraulic energy. The engine is prone to the following faults during its use.

Q: What is a solution pump?: (4) smooth running, low noise, no lubrication, no lubrication and low noise due to the absence of rolling bearings and motor fans(5) a wide range of use, the high temperature, high pressure, low temperature, high melting point and other conditions are able to meet the requirements2.2 shielding pump shortcomings(1) because the shielding pump adopts sliding bearings and is lubricated by the medium to be transported, the medium with poor lubricity should not be transported by shielding pump. Generally, the viscosity of the pump medium is 0.20mPa.s.(2) the efficiency of shielding pump is usually lower than that of single end mechanical seal centrifugal pump, which is approximately equal to that of double end mechanical seal centrifugal pump(3) long time in small flow operation, shielding pump efficiency is low, will lead to heat, make the liquid evaporation, and cause the pump to dry, and thus damage the sliding bearingsCanned pumps can be divided into the following types: 1) basic type 2) reverse circulation type 3) high temperature type 4) high melting point type 5) high pressure type6) self priming 7) multi stage 8) mud type

Q: What is the pump lift voltage? And how to suppress the pumping voltage rise?: [suppression of pumping voltage] the general use of the installation of absorption resistance to absorb the pump voltage rise. The simplest way to control the pump voltage is to connect the DC bus with an energy consumption resistor before releasing the pump voltage.

Q: If you use an ordinary 15W submersible pump, put it in the tank, if the leakage, the fish will hang it?: If the fish tank is made of metal, the fish tank is grounded or connected to the zero line, and then the fire line is put into the water, then your fish will be electrocuted immediately. Go back to the submersible pump, submersible pump line and the zero line very close, even if the firing line and the zero line at the same time the leakage occurs, fish could not swim between the firing line and the zero line, so the tank submersible pump leakage will cause the following hazards: 1, electric shock. 2, submersible pump short circuit. 3, the submersible pump serious fever, resulting in water temperature tank.

Q: I would like to ask, constant pressure pump set pressure 20Mpa, the actual load is 15Mpa, then the constant pressure pump outlet pressure? If it is 20Mpa, then where is the loss of 5Mpa? If 15Mpa, the constant pressure pump 20Mpa how to understand? In addition, the constant pressure pump pressure is defined when the flow began to reduce the point, or a sharp drop in flow after the point?: Constant pressure pump is pressure maintained at the set pressure, flow control valve according to the order, there is pressure to set, after the pump displacement is reduced, as for how to reduce emissions, to see how much you need to flow.

Q: What is the displacement of the pump? Flow? What is the volume efficiency and mechanical efficiency of the pump?: Pump flow: the volume of liquid discharged per unit time.(3) volume efficiency of pump: the ratio of actual output flow of pump to theoretical flow rate.

Q: How many square cables does the submersible pump for 7.5KW need?: According to current I=13A, it is estimated that the cable is less than 10 square meters, so the cable cross section can be calculated at the ampacity of 5A per square meter. The square section of the cable is =13/5=2.6 square. According to the specifications series, optional 2.5 square aluminum cables. When the cable is longer, it is safer to choose 4 square aluminum cables.

Q: Common failure treatment of piston pump: x09x09 (3) no connecting key on pump shaft or motor shaft1) break2) missing x091) replace key2) patch keyx09x09 (4) pump internal slide vice stuck1) the clearance is too small2) parts accuracy is poor, assembly quality is poor, gear and shaft coaxial deviation is too large; plunger head clamping; blade perpendicularity difference; rotor pendulum difference is too big, rotor slot has wound or blade has scar, force after fracture and stuck

Q: Centrifugal pump flow, why can be adjusted through the outlet valve? Can the flow of the reciprocating pump be adjusted in the same way?. Why: Centrifugal pump, and is a very common method of centrifugal pump, flow with the head (or pressure) increases, off a small valve resistance increases, the pump head should be increased, then the flow decreased, whereas open valve flow increase

Q: Why is the submersible pump tripped on an electrical switch?There is no electrical leakage protection, directly connected to the circuit breaker, and when the switch on, the circuit breaker jumpedI checked the line is good, the pump did not break down, is not the water pump?: There should be the following reasons: 1) the setting value of the trip switch is too small, and the operating current of the submersible pump exceeds its setting value, and the switch is tripped
