Electric pressure test pump is mainly used for hydraulic test

  Electric pressure test pump is mainly used for hydrostatic test of various pressure vessels, oxygen cylinders, pipelines, valves, steam boilers, new pre stress processing technology and equipment to obtain liquid high-pressure source in the laboratory
It is a very new series of products designed by the pressure test pump joint design group of the General Machinery Research Institute of the Ministry of machinery industry
It has the & ldquo; Three modernizations & rdquo; It has the characteristics of high degree, long service life, stable performance, flexible movement and light weight
On this basis, the transmission device and cross conversion are added, so that the comprehensive value of this series of products can fully meet the requirements, various performances are stable and reliable, the use is more safe and convenient, and the effect of energy saving and power saving is achieved at the same time
In terms of product structure, closed water tank is selected to reduce the height of the whole machine and make the appearance more compact and beautiful
The product is based on 5 & deg& mdash; 60 ℃ clean water, emulsion and oil with viscosity no more than 45mm2 / s are specially designed as working medium, and the working ambient temperature of the pump is 5-deg& mdash; 60℃。 Generally, the factory always takes the working pressure, high-pressure flow, low-pressure flow, high-pressure plunger diameter, voltage, motor power, etc
To determine the price of the pressure test pump
The higher the parameters, the more expensive the price will be
1、 When purchasing high-pressure pressure test pump, pay attention to its model and flow
If the selected specification is inappropriate, it will not be able to obtain sufficient water output and give full play to the efficiency of the unit
The high-pressure pressure test pump does not start and cannot make water
Check whether the power is cut off and whether the plug is inserted properly; Check whether the low-voltage switch fails and cannot be connected to the power supply; Check whether the pressure switch or water level controller fails; Check whether the transformer and fuse are burnt out
? 2、 When installing the high-voltage pressure test pump, the cable should be overhead and the power line should not be too long
Do not force the cable when the unit is launched, so as to avoid breaking the power line
Do not sink the high-pressure pressure test pump into the mud, otherwise it will cause poor heat dissipation and burn out the motor winding
3、 The solenoid valve fails to cut off water effectively; Inspection method: close the ball valve of the pressure drum
If there is still waste water, it can be concluded that the solenoid valve fails); In another case, close the water inlet solenoid valve and then open it
If the machine is normal, it is judged that the water pressure is too high, resulting in the solenoid valve can not be closed flexibly
Consider adjusting the water inlet general valve to reduce the water pressure; Check valve pressure relief (inspection method: close the inlet solenoid valve
If there is still waste water, it can be determined as check valve pressure relief)
4、 Do not let the high-pressure test pump run overload for a long time, and do not pump water with large sand content
The dehydration operation time of the high-pressure test pump should not be too long to avoid overheating and burning the motor
During the operation of the unit, the operator must observe whether its working voltage and current are within the values specified on the nameplate at any time
If not, stop the motor, find out the cause and eliminate the fault
5、 Check the motor more often at ordinary times
If cracks are found on the lower cover, damage or failure of the rubber sealing ring, it shall be replaced or repaired in time to prevent water from penetrating into the machine
In addition to the different requirements of the transmission object for the structure of the high-pressure test pump, new requirements are put forward for the internal or external structure of the high-pressure test pump in terms of the installation form, pipeline layout form, maintenance and repair of the high-pressure test pump
At the same time, various manufacturers have added their own enterprise ideas to the structural design, which has further improved the diversification of the structure of high-pressure pressure test pump
