1. Installation of sound insulation cover Install sound insulation cover for water injection pump unit to cut off the transmission of noise from motor and water injection pump. Experiments show that noise reduction can be reduced by 15% ~ 30% after using sound insulation cover.
2. Control of noise transmission and reflection Pumping stations in the oil pumping stations in the pump room, the use of a variety of sound-absorbing materials and damping devices, such as asbestos sound-absorbing panels, shock absorbers, damping springs and other reasonable arrangements to effectively control the noise The spread and reflection.
3. Isolation measures to isolate workers duty room and pump room, observe the operation of water injection equipment through double glazing observation window.
4. The introduction of new technology of water injection production introduction MCS distributed control system, improve the efficiency of water injection system, equipment, good equipment and automation level, while reducing the vibration and noise equipment, optimizing system operation, not only improve the oilfield water injection system Work efficiency, but also to water pump units before and after the vibration at the bearing at 0.5mm below the noise control of the pump room below 90dB, at present in six high-pressure water pumping station to promote the use of the system, and through the local area network to achieve a water injection station Long-distance real-time monitoring of the production process.
5. Selection of low noise equipment to promote the use of frequency control device, not only can reduce energy consumption, but also reduce the noise of water injection pump units, since 2000, has installed frequency control equipment 9, of which power 2000kW, operating voltage 6kV high-voltage frequency control equipment 1, power 160kW, working voltage 380V low-voltage frequency control equipment 8, at the same time to save investment costs to take advanced "a control two", "one control three" and other technology and measures, Water injection pump noise significantly reduced.

Mounted units are two part assemblies: The housing and the bearing insert. There are several housing options that are considered [stock" housings; these are very common in the power transmission industry. Mounted unit inserts come in a variety of styles. The most common are radial ball bearing inserts, tapered roller bearing inserts, spherical roller bearing inserts, and plain bearing inserts. Bayview bearing & Supply stocks all common sizes in our Egg Harbor City warehouse.
Ball Bearing Mounted Units – Ball bearing mounted units are the most common unit in the industrial market. Ball bearing mounted units utilize a ball bearing insert and can be purchased as greaseable or sealed for life.
Tapered Roller Bearing Mounted Units – Tapered roller bearing mounted units, or Type E bearings, are a mounted unit that utilizes a tapered roller bearing cartridge insert. Type E bearings offer a higher load and speed ratings than ball Bearing Units.
Spherical Roller Bearing Mounted Units - Spherical roller bearing mounted units is another type of housed bearing.  Spherical roller units offer the highest load ratings available and can adjust to misalignment.
Plain Bearing Units- Plain bearing units are the original mounted units. Plain bearings can be made of 660 Bronze, wood, or lead. These units have high load and temperature ratings, but cannot run at a high RPM.
