Electric pressure test pump selling points:

1. This series of pumps adopts a closed water tank with compact structure, stable operation, beautiful appearance and convenient movement.

2. This series of pumps is a four-piston reciprocating pump. The plunger, water inlet and outlet valves, safety valve core and hydraulic control valve core are all made of stainless steel, and the safety valve body and hydraulic control valve body are made of copper.

3. Equipped with a hydraulic control valve, which can automatically adjust the high and low pressure flow. When the pressure is below 1.6 MPa, the flow is large and can be quickly filled with water and pressure. When the pressure is above 1.6 MPA, the flow is automatically reduced by the hydraulic control, which can be stable Increase the pressure to reduce the impact on the container under test and protect the low pressure cylinder.

4. Equipped with a transmission box, which can store lubricating oil and save lubricating oil.

use

  This pump is used in all kinds of pressure vessels, boilers, pipe fittings and other places where pressure test and strength test are required. The pressure value can be pressure tested according to the needs, and the pressure can be automatically maintained. Equipped with cleaning accessories, the machine can also be used as a cleaning machine. The delivery medium of the pump is generally clean water at room temperature. Emulsion, anti-rust water and neutral oil with a viscosity similar to that of water can also be used.

  The pressure test pump system is a non-standard equipment. The industry needs of each customer are very different. The pressure test pump control system that is made is naturally different. It basically has the following functions (1) It has the function of manual pressure or automatic pressure. . (2) Sectional test procedures can be set within the pressure test range, and the system will automatically boost, shut down, and maintain pressure when pressurizing. (3) The system has automatic unloading function, container automatic unloading, emergency stop and overpressure automatic unloading function. (4) The pressure holding time preset during the pressure test can be set freely. (5) With real-time pressure display, curve display, time display, working status display, etc. (6) The system has the functions of pressure setting, calibration and software zero correction. (7) It has the functions of system overpressure and fault status feedback. (8) It has the function of automatically distinguishing the pressure-holding state of the container under test in the pressure-holding stage.

  Main structure and working principle: The product is a horizontal 2-cylinder reciprocating pump. It is composed of main components such as motor, reduction box, transmission box, water tank, water collector, safety valve and water tank.

The pump is installed on the cover of the water tank, and there are four rollers under the water tank, so that the pump can move flexibly. The motor and the gearbox are connected by two half couplings. The speed ratio of the worm gear shaft and the worm gear in the reduction box is 2:55. The two ends of the worm gear shaft are provided with eccentric shafts forming 180° each other, and the rotary motion is converted into the reciprocating motion of the slider and the cross head through the sliding mechanism in the transmission box on both sides. The plunger installed on the crosshead reciprocates in the water tank to realize the alternate suction and discharge process of the pump.
