Before the equipment is used, it will be prepared for the use of its components and the environment during operation, and the equipment will be used more smoothly afterwards.The plate heat exchanger is also required to be prepared before use, so that its heat exchange efficiency can also be improved.
Plate heat exchanger need heck whether the clamping studs are loose before using , and the clamping dimensions are in accordance with the installation drawings.If the requirements are not met, the studs shall be tightened according to the dimensions specified in the installation drawings. The circumference shall be uniform so that the parallelism error of the two compression plates does not exceed 2 mm.
The plate heat exchanger can be hydraulically tested on the hot side and the cold side at a working pressure of 1.25 times before use. The pressure is maintained for 30 minutes, and all sealing parts of the equipment should be leak-free before they can be put into use.The test pressure and holding time can also be carried out according to the system regulations, but the test pressure must not exceed the product nameplate test pressure value.Disabling sewage to do water pressure test to avoid water corrosion of the plate.
An exhaust valve should be placed in the plate heat exchanger to remove air from the medium and prevent the gas from staying in the device to reduce heat transfer efficiency.The connection of the hot and cold medium inlet and outlet pipelines of the plate heat exchanger shall strictly comply with the specifications of the inlet and outlet of the hot and cold medium of the product, and the wrong connection will lose the operation effect or cause an accident.The plate heat exchanger itself has a seal and inspection of equipment such as an exhaust valve.If it is found that the equipment is faulty as soon as possible to solve the problem, it will avoid affecting the subsequent work process.
