1, Gear pump selection and installation
Gear pump should be carried out in ss gear pump manufacturer specification of accordance with the liquid delivery by choice, performance, and check the need analysis of the suction and discharge conditions, is intermittent operation or continuous operation, etc.Usually should be in or near the manufacturer design rules of pressure and flow rate under the condition of operation.When the pump installation should undertake the following review:
(1) basic size, location, elevation should meet the design requirements, the anchor bolts must be properly and correctly fixed in the concrete foundation, the machine should not be missing parts, damage or corrosion, and so on and so forth;
(2) according to the properties of the pump is conveying medium, when necessary, should check the main parts, shaft seal and gasket material;
(3) the leveling of the pump, is to get a job should comply with the provisions of the equipment technical documents, without rules, should be consistent with the current national standard “mechanical equipment installation engineering code for construction and acceptance of the general regulations;
(4) all the pipe connected to the pump body, the installation of the pipe and oil pipeline cleaning requirements shall comply with the provisions of the relevant national standards.
2, the use of stainless steel gear pump
The test run of electric gear oil pump shall meet the following requirements:
(1) the steering should be the same as the pump to drive;
(2) find out the pipes and coaxial pump to;
(3) all the fixed connection parts should not loose, the lubrication parts filling specification and quantity of lubricant should comply with the provisions of the equipment technical documents;Botou city tai bang the products of the pump valve manufacturing co., LTD
(4) there is a requirement for prelubricated prelubricated part should be in accordance with the provisions;
(5) the indicating instrument, safety protection devices shall be sensitive, accurate, and reliable;
6. Barring should be flexible, no abnormal phenomenon;
7) should be done before the china hot oil pump in the test run the pump body preheating, temperature rise should be uniform, should not be greater than the temperature of 500 ℃ per hour;Pump body surface and has a working medium import process piping temperature difference should not be greater than 4090;
Was set up to eliminate the influence of temperature rise of connection device, bypass connection device to provide cooling water.
stainless steel gear pump operation should pay attention to the following:
(1) prohibit oil-free operation, don’t adjust the suction population to reduce emissions, banned under low flow rate;
(2) to monitor the operation process, completely prevent leakage of stuffing box, the replacement of packing box to use the new packing;
(3) to ensure that the mechanical seal are fully rinse of water, water bearing it is prohibited to use too much water;
(4) lubricant don’t use too much;
5. According to the recommended inspection cycle.Establish the operation records, including operating hours, packing adjustment and replacement, adding lubricants and other maintenance measures and time.For stainless steel gear pump suction and discharge pressure, flow, input power, lotion and bearing temperature and vibration should be measured records on a regular basis.
