4D-SY3.5MPa large flow pneumatic pressure test pump details
As we all know, each product has a lot of models, of course, there are many models of large flow test pump, 4D-SY3.5MPa Is a common kind, the following first to talk about 4D-SY3.5MPa large flow pneumatic pressure pump it! First, an overview 4D-SY / 3.5-type electric pressure test pump is electric four-plunger, reciprocating pump pressure test for high pressure vessels, piping equipment, boiler systems, machines and other test water pressure purposes. Working medium is water, emulsion or kinematic viscosity is not greater than 45mm2 / S oil. 4D-SY / 3.5 working performance as follows: 1, the maximum working pressure: four plunger work: 2.8Mpa / cm 2 two plunger work: 3.5 Mpa 2, flow: four plunger work: 1120 liters / h Two plunger work: 560 liters / h 3, plunger diameter: Plunger (4): 46mm 4, long stroke: 67mm 5, the reciprocation frequency: 42 times / min 6, shaft power: 2.2KW 7 , Equipped with electric power: 3KW 8, with motor speed: 1450r / min Working environment: 5 ℃ -60 ℃ Second, the structure of the pump from the motor through the flexible coupling to the worm gear. In the worm shaft equipped with two eccentric wheels, the role of the conductor and the slider, the rotary motion into a plunger reciprocating motion. Four plungers are connected to the conductor, and four water tanks are fixed on both sides of the gearbox so as to be left and right symmetrically. Gearbox base mounted on the water tank, the lower tank equipped with four iron wheels for mobile use. Pump outlet equipped with safety valve, adjustable pressure value of 2-3.5Mpa. When the test pressure exceeds the specified value. The safety valve opens automatically to prevent accidents. Third, start, run and stop 1, before driving preparatory work: (1) Check the lubricating oil surface in the gear box to keep it in the oil line of the oil. (2) Check the water used in the tank is clean, does not allow the use of sewage containing sediment, so as not to plug the pipeline, worn plunger or valve failure caused by the failure to close. (3) Check and tighten the plug. (4) Select the appropriate pressure gauge mounted on the cylinder (working pressure is not greater than two-thirds of the gauge pressure) (5) the pressure vessel and pump flange connection. (6) Check the circuit insulation and safety conditions. (7) Finally start the motor, the motor before the start of the return valve to open (that is, the handle in a horizontal position). So that the water tank does not occur under the pressure of water until the normal operation of the motor and then close the return valve. (Handle drop position) (8) Adjust the safety valve to be tested to meet the pressure required by the pressure vessel. 2, start: open the return valve to start, (ie, the handle of the communicator is in a horizontal position) so that the water tank does not produce water pressure. Then open the exhaust valve, exhaust valve drainage, close the exhaust valve. Normally close the return valve. (Communicator handle sag position) 3, running and parking: (1) Close the return valve, the four cylinders work at the same time, for water. (2) When the pressure reaches 2.8Mpa after filling water, open the backflow valve again (the handle of the communicator is in a horizontal position). The two high-pressure cylinders work alternately to make the pressure rise slowly. (3) After the required pressure has been reached, stop the vehicle, stop at the required time and inspect the test container. (4) Precautions during operation: (1) The gear box shall be uniformly noise-free, noise and blockage during operation. ② gearbox lubricant should be maintained below 80 ℃, the maximum does not exceed 85 ℃. ③ If any sediment is found during the work, stop work immediately and carry out overhaul. No water leakage is allowed. ④ working pressure does not allow more than 3.5Mpa. ⑤ gas cylinders should maintain a certain amount of air to reduce the pressure gauge by the pump pressure pulse. Above describes in detail the 4D-SY3.5MPa large flow pneumatic pressure test pump performance, structure, starting, operation and stop, I believe that you have a larger flow pneumatic pressure test pump has a deeper understanding, but also hope you will be able to follow up Master it.
