It is a new technology enterprise integrating design and research and development, production and sales, after-sales maintenance, and import and export trade. The company is located in the western part of Taian, 5 kilometers west of Taian Station.

Since its establishment, our company has continuously innovated and developed, steadily advancing, and has successively passed the EU CE certification and ISO9001 quality system certification.,Products cover all over the country and are exported to countries such as South Korea, Japan, Malaysia, Vietnam, the Philippines, Myanmar, Thailand, Indonesia, Angola, Saudi Arabia, Congo, Spain, Germany, Austria, Peru, and the United States.

Tiancheng TestingEquipmentEstablish high starting points, high goals, high quality, high efficiency, and beneficial "five high" standards to manufacture high-quality products and obtain a broad sales market. The company serves a wide range of users with good reputation, strong strength, good products, and low prices. Below, I will give a general introduction to the maintenance methods and precautions for pipe static hydraulic testing machines.

When usingthe pipe static hydraulic testing machine, in addition to some precautions to pay attention to, it is also important to understand the maintenance methods of the pipe static hydraulic testing machine. Below, the editor will lead everyone to understand.

The instantaneous burst test of pipes refers to the rapid and continuous application of liquid pressure to a given segment of plastic pipe sample, causing the sample to rupture in a short time. Read the pressure value at which the sample ruptures and calculate its circumferential stress. The pressure control system of the static hydraulic testing machine consists of a pressurization pipeline and electrical control. The inlet of the pressurization pipeline is connected to an external pressurization pump, which is used to pressurize the sample according to the test conditions. The pressure transmitter detects the sample pressure to transmit pressure information to determine whether the pressurization pump needs to start pressurizing. Each line on the control cabinet is equipped with an electromagnetic valve. When the pressure is constant, the corresponding electromagnetic valve closes; when the pressure is insufficient, the electromagnetic valve opens to supplement the pressure. The pressure supplement method of this testing device adopts an advanced intermittent pressure supplement method to keep the pressure range constant. The output pressure of the control cabinet is connected to each sample interface of the constant temperature water tank via high-pressure hoses.

Maintenance methods for pipe static hydraulic testing machines

1. The main unit and the medium constant temperature box must be reliably grounded.

2. The safety valves in the various main units of this machine have been adjusted before leaving the factory and should not be changed arbitrarily. If during the test, it is found that a certain line has overpressure and cannot return to a lower pressure, or if the pressure cannot be supplemented after pressure relief, consult the supplier for appropriate adjustments.

3. Before the test, the main pressure regulating valve and one burst hand valve should be opened, and the main pressure relief valve should be closed, then operate according to the operating procedure.

4. Fill the high-pressure pump water tank with softened water, and add softened water as needed. When using for the first time or after a long period of disuse, first open the main pressure regulating valve and pressure relief valve, let the pressurization pump work for a few minutes to exhaust the air in the pipe, and then operate according to the operating procedure.

5. If the electric contact pressure gauge and the test pressure values of each branch show frequent changes, there may be a leak. Check whether the pressure relief valves of the corresponding branch and main line are closed, or check whether the sample clamping is installed tightly and the connection status of each high-pressure pipe.

6. The output high-pressure hose should not be used to directly lift the sample to avoid damage.

Precautions for operating the pipe static hydraulic testing machine.

1. Keep the manual for reference. Before using this instrument, be sure to read this manual carefully.

2. Do not place the instrument on an unstable surface.

3. Use the instrument under specified power supply conditions.

4. Do not place any items on the main power line of the static hydraulic testing machine, and do not place the instrument in a location where people can step on the power line.

5. If this product uses an extension cord, ensure that the rated current of the original power cord is consistent with that of the extension cord.

6. Do not move any panels of the instrument, and do not place any items on the body. Failure to comply with this operating procedure may result in fire or electric shock hazards. Do not spray any liquid on the main body.
