The pressure automatic control electric pressure test pump is a three cylinder horizontal electric pump, which adopts & ldquo; I & rdquo; The zigzag cylinder structure has the characteristics of large flow, high efficiency, stable operation, stable performance, good operation performance and convenient maintenance; It has the functions of automatic pressure maintaining, manual pressure boosting and unloading
The pressure automatic control electric pressure test pump not only has the characteristics of compact structure, safety and reliability, large flow, high efficiency, high pressure and wide coverage, but also has wide application range, strong compatibility, simple operation and convenient movement
The pressure test pump can use the motor or diesel engine as the power source, which is suitable for indoor, outdoor or field operation without power supply
The pressure test pump is used for all kinds of pressure vessels, boilers, pipelines, valves and other places that need pressure burst test and strength test for blasting and pressure test; It can also be used for oil field wellhead and water injection
The test pressure can be increased from atmospheric pressure to rated discharge pressure
With wyc microcomputer control system, full automatic remote operation can be realized
Before using the pressure test pump, check and adjust whether the connecting parts at all places are loose
Whether the water inlet and outlet pipes are unblocked and whether the water in the water tank is clean
It is strictly prohibited to use sewage containing fiber sediment and sundries to prevent affecting the service performance of the pump
After inspection and adjustment, connect the pressure tested vessel with the working connecting pipe
Close the drain valve needle, open the control valve needle, and then float the operating handle up and down
The force shall be uniform to avoid impact, so as to make the plunger move back and forth
The clean water in the water tank is sucked into the low-pressure cylinder through the suction pipe, enters the high-pressure cylinder and the controller, and flows into the pressure tested container through the working connecting pipe
Its pressure value can be read out from the pressure gauge
During pressure test, the pressure shall be within 2 / 3 of the very large indication value of the pressure gauge
The large working pressure shall not exceed the rated discharge pressure specified by the pressure test pump of this model
Calibration process of electric pressure test pump:
1
The pressure test shall be carried out in strict accordance with the provisions of the pressure test requirements, and the pressure test pieces shall be neat, clean and easy to inspect
Before the pressure test, check the electrical system and grounding, check the pressure gauge, check whether the operation and lubrication of the pressure test pump are good, and the very large degree of the pressure test gauge shall not be less than 1
5 times of the test pressure
2
During the preparation of pressure test, the position of water inlet and outlet shall be arranged
When filling water for pressure test, open the exhaust hole first, remove the pressure gauge to drain the air in the container
When the exhaust hole and the connecting port of the pressure gauge give water, install the gauge and close the exhaust hole
3
The pressure rise must be slow and overpressure is not allowed
Hammering is not allowed after the pressure test piece rises to a certain pressure
If defects are found in the test piece and pipeline, the pressure shall be reduced to zero before treatment
It is not allowed to work under pressure
4
Negative pressure and low-pressure test pieces and small containers can be boosted to a certain pressure at one time, and then pressure holding inspection can be carried out
The test piece with large volume can be boosted and inspected in sections
5
The pressure test piece must be placed stably, and the pressure test part shall not leak after inspection
6
After the pressure test, drain the water and remove the bolts after pressure relief
After the pressure test in winter, drain the water immediately to prevent the equipment from freezing
7
The bolts shall be tightened to ensure uniform stress and prevent local deformation and fracture
8
The pressure test pump shall be operated by a specially assigned person
More than two people must be assigned for each pressure test, and a specially assigned person shall be assigned to command
Before water drainage, stick to the post
9
The defective parts to be inspected shall be marked and the pressure test record shall be filled in
Maintenance of electric pressure test pump:
1
The surface of the pump, the lubrication in the reduction gearbox and transmission box, and the pressure test medium in the water tank must be kept clean and free of dirt or other sundries
2
The lubricating oil for a new pump should be replaced after 56 hours of operation, and then every 500 hours of operation
3
The pump that has been out of service for a long time shall be subject to anti-corrosion treatment
The pressure test medium shall be drained first, and the antirust oil or antirust water shall be pumped once
The surface of another unpainted part shall be coated with engine oil for rust prevention
4
Always pay attention to the axial clearance of the worm gear pair of the pump
The worm is 0
04 & mdash; 0
07, worm gear 0
05 & mdash; 0
10
If this value is not met, adjust the paper pad of the through cover or side cover
5
When the ambient temperature is below 0 ℃ and the working medium is water, antifreeze should be added
It is recommended to use alcohol as antifreeze, and the proportion is listed in Table 1
