Q:What's the smell of petrol in the car and the trunk?! Especially after a long drive!

Have changed the gasoline pump, or because of the failure to disassemble the steam pump owners, if the car appeared gasoline, do not panic, this is because after the disassembly and assembly, the residue is not cleaned up. In fact, this situation is usually not met, the gasoline pump replacement cycle is 100 thousand kilometers. But now the gasoline filter is also installed in the tank, connected with the gasoline pump, and its replacement cycle is shorter, 40 thousand km, when the replacement of gasoline pump disassembly. In this case, just look at the gasoline pump installed is not correct, in cleaning the perimeter can be.

Q:What's the cause of a default like a general rubber product?

Measures to prevent aging: from the point of view of aging, one of the main reasons is the polymer structure itself. Therefore, it is important to improve the structure of polymers to improve their aging ability. For example, in rubber vulcanization, there are still unsaturated double bonds, and rubber products in use and it is difficult to avoid the erosion of sunlight, oxygen, ozone, so people on the synthesis of new varieties, to avoid or reduce the polymer chain of rubber double bonds, such as ethylene and propylene two monomer by copolymerization made two yuan B two rubber, different from other synthetic rubber is one of the major characteristics in the structure of the backbone is not completely saturated with double bond, making it the most ozone resistance, chemical resistance, high temperature resistant rubber aging; there is a kind of antioxidant, such as adding oxygen or ozone to prevent aging caused by antioxidants. Add UV stabilizers, heat stabilizers, preservatives and other unfavorable factors, and caused by aging.

Q:Is the rubber pipe joint installed in the middle of the pipe and pump to absorb the shock?

A pump is a machine that transports liquids or pumps liquids. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids. Pump performance of technical parameters are flow, suction, lift, shaft power, water power, efficiency, etc.; according to the different principles of work can be divided into volume pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.

Q:The basic buret is a rubber tube is inlaid with a glass bead to replace glass piston. Why this burets cannot be used to install Potassium Permanganate solution?

The rubber tube can be Potassium Permanganate oxidation

Q:Method for inserting glass tube into rubber tube when assembling instrument

The sleeve method of different outer diameter glass tube should be determined according to the size of the outer diameter. If the outer diameter of the two tubes is not big, then the rubber tube with the same inner diameter can be connected. When connecting to the rubber sleeve in the larger outer diameter glass tube, the specific method, with a diameter from one end of the rubber tube of the same stick (such as chopsticks) inserted into the connection end to the rubber tube, rubber tube set in reverse, then the larger outer diameter glass tube against the wooden stick. The rubber hose forward turning sleeve on a glass tube, stick out.

Q:How to determine the tensile strength of GB rubber joint?

The tensile strength test specimen is dumbbell shaped and can be divided into 1, 2, 3 and 4 types, of which type 1 is universal, and the specific dimensions of each part of the sample are as follows:For non-standard specimens, that is, the maximum thickness of the narrow part of the sample taken from the finished product is specified as: type 1 is 3.Omm, type 2 and type 3 are 2.5mm, and type 4 is 2.Omm.

Q:The difference between the rubber pipe and PE pipe?

PE is one of the most basic plastics of polyethylene plastics. It has a good economy, and should have a series of advantages, such as stable and reliable interface, material impact resistance, anti cracking, aging resistance and corrosion resistance. Plastic bags, plastic wrap and so on are PE, HDPE is a high crystallinity, non-polar thermoplastic resin.

Q:Is hot melt hose toxic and harmful?

The heater adopts the U.S. and high temperature heating wire line, uniformly wound around the pipe wall, with thermal insulating properties and uniformity, good heat resistance, heat insulation material of high quality, ensure that the insulation performance of larynx.

Q:How do you remove the burrs on the rubber joint quickly?

The thickness of the rubber joint burr than the thickness of the product is much thinner, so brittle speed than the speed burr brittle products quickly, in burr brittle and brittle products without this period of time can be hit by projectile projectile with frozen products deburring machine, thereby removing burrs in embrittlement.

Q:The use of anti slip rubber joints under what circumstances?

The appropriate model must be selected according to the working pressure, connection mode, medium and compensation amount of the pipeline, and the quantity is chosen according to the requirements of noise reduction displacement.
