Submersible motor pump is composed of submersible motor centrifugal pump, limited by the diameter of the wellbore, the entire device is very long, limited by the means of transport and downhole equipment, submersible pump composed of multi-stage connection, due to vibration during work, linking her fracture Frequent problems, resulting in oil wells do not need operations for pump. Pumps are expensive, coupled with lost production and operating costs, can cause significant damage to each joint failure problem: To reduce the economic losses caused by vibration, the vibration law must be studied and the vibration parameters need to be tested. Submersible electric pump device is composed of the main body, on the file cap, jacket, test equipment, the next cap, the next joint. The main body has a through hole, there is a test groove to install the test instrument, the main package jacket, sheath longer, processing difficulties, the sheath can be made of multi-section series, the inner surface of the jacket is equipped with test equipment through The lower part of the main body is connected with the lower joint and the lower joint so that the sheath can not move axially; the testing instrument is installed in the round hole formed by the embedded groove on the main body and the through groove on the inner surface of the sheath; , The lower part of the test equipment installed under the cap. The surface of the jacket has a cable duct for the cable that is used to power the motor at the lower part of the unit. Work, the oil drawn out from the body through the hole, the device into the well, the tester and the submersible pump is integrated, submersible pump work, the test equipment with the pump vibration, vibration parameters through The cables on the test equipment were taken to the ground. The device won the national patent.
According to the adherence requirements of the product, cells are divided into three categories:
Suitable for suspension culture of common cells and tissues;
The standard type has good cell adhesion performance and is suitable for cell adhesion growth;
Dedicated containing cell pastes (cell clusters that can be used in some special cases, such as cell walls, cell surfaces and secretory cells).
According to the shape of the instrument, it is divided into:
Wide body culture flask;
triangle bottle;
Torticollis flask.
cell culture flask,filter cap cell culture flask,suspension culture flasks,cell tissue culture flask
