Q:What is a limiter?

The compensator of the inner sleeve shall be noted that the direction of the inner sleeve is consistent with the direction of the medium flow, and the hinge rotation plane of the hinge type compensator shall be in accordance with the displacement rotation plane.

Q:What are the main uses of a bolt tensioner?

But the general does not hurt the threaded bolt tensioner, high precision, high tensile bolt General requirements is the most appropriate, domestic stretcher good brand, I recommend Prima, quality customer service is good, and I hope to help you!

Q:Is the construction of the water supply steel pipe a telescopic device?

When building management personnel to operate, strict inspection, selection of qualified brick factory with the same specification, on the masonry staggered, a brick, mortar and uniform horizontal mortar joint concave mortar, should take 5--8cm, wells and vertical mortar joint width not less than 5mm, while laying on the edge of a mud brick rub a squeeze, the slit into pulp, necking, measuring layers with a ruler, each layer in size, surrounded by flavours of not more than 3cm, three flavours of not more than 4cm, to ensure the quality.

Q:What is a bolt tensioner? How do you use it?

Pretension is a familiar term in machinery, architecture and other fields. General general description: in the connection (connection mode and use is various, before the work load is), in order to enhance the reliability of the connection and close, to prevent the load by connecting cracks or slip and pre applied force between.

Q:What are the main uses of a bolt tensioner?

He is elastic, in his range of elasticity can be stretched, and generally does not hurt the threaded bolt tensioner, high precision, high tensile bolt General requirements is the most appropriate, domestic stretcher good brand, I recommend Prima, quality customer service is good, and I hope to you help!

Q:The working principle of the bolt tensioner

A bolt tensioner consists of a hydraulic pump, a high pressure hose, a pressure gauge, and a stretched body. The hydraulic pump is the power source, the pressure meter reflects the output pressure of the pump, and the high pressure hose is connected with the hydraulic pump and the drawing body. A drawing body is an actuating element for realizing a bolt stretching. The utility model is mainly composed of a piston cylinder, a piston, a supporting bridge and a stretching nut.

Q:What kind of materials are used in the telescopic equipment of machinery industry?

The most common form of bond failure is shear. So the key requires enough strength and steel. No. 45 is the most commonly used steel.

Q:What are tensile and shrink wrapping?

Stretch packaging began in 1970s as a new packaging technology developed from shrink packaging. Stretch packaging is a packaging method that relies on a mechanical device to wrap the elastic film around the package at room temperature and seal it at the end thereof. Since stretching packaging does not require heating, the energy consumed only shrinks by 1/20 of the package. Stretch wrap can bale single items, can also be used for packing pallet packaging, set.

Q:Mechanical structure and principle of automatic focusing lens for camera

From the basic principle, AF can be divided into two categories: one is based on the camera and photographed location AF target distance between measurement and another is based on the focus screen clear focus imaging detection.

Q:What is the automatic telescopic function of an automatic umbrella?

When the intermediate slider is moved upwards, the switch is moved upward to prevent the spring 2 from compressing the spring at the lower dead point position and the elasticity does not reach the maximum value. Only when the switch force is slightly greater than the maximum value of spring 2 elasticity, the convex switch is retracted, and the middle slider begins to move up.B. when the middle slider moves down, the upper half of the convex switch is smaller, so that the spring 1 has sufficient elasticity to make the middle slide switch locked by the convex point switch. And 2, 3 is not enough to cause the umbrella middle slider has been declining.
