1. Cleverly installed cylinder. Winter; because the weather is cold; the water blocking ring becomes brittle; it is simply cracked when it is placed on the cylinder liner. Before the device; the water blocking ring can be immersed in warm water of about 60 °C for 5 minutes; The rear device is not easy to break.
2, cleverly installed rolling bearings. When installing rolling bearings; directly hit with a hammer; easy to deform the bearing; affect its service life. Now analyze a simple device approach: choose a 600 watt bulb to the power supply; use it to heat The bearing of the device; the heating time is 5 to 10 minutes; the heating temperature is maintained at about 110 ° C; do not exceed 120 ° C; then the bearing is agile on the shaft.
3. Cleverly repair the clutch pedal. The clutch pedal is smoothed after the horizontal stripes; when the pedal is pressed; the foot is easy to slip out. The rainy weather is easy to slip. If the upper and outer sides of the pedal are welded with a proper length of rebar; The pedal plane is 5 mm; it will not slip when used.
4, Qiaozhi tires slowly leaking. Take two tablespoons of talcum powder; remove the valve core; let the inner air be exhausted; use a hard paper to make a funnel into it; fill the talcum powder into the inner tube. Then install the valve core enough Gas; talcum powder is attached to the inner sidewall of the tire in a filled state; it can block small pores from leaking.
5. Remove dirt from the fine filter. The dirt and dirt in the rotor oil filter are not easy to remove. If you use a layer of paper on the inner wall of the rotor, let the soil adhere to the paper; remove the paper when protecting. The soil can be completely removed.
6. Check the cracks of the parts. Place the parts in the kerosene; take them out after a while; dry the surface and sprinkle a layer of white powder; then gently tap the parts with a small hammer; if there is a crack; The igniting oil that has been immersed in the crack is exuded from the crack; the crack is displayed on the white powder.
7. Cleverly disassemble the old cylinder liner. Use the old piston pin to load the old piston of the machine; install one or two old piston rings on the old piston; hook the old piston pin with a small steel bar with a diameter of 6.50 mm. The piston is reversely loaded into the cylinder; when the piston ring exceeds the lower edge of the cylinder liner; the cylinder sleeve is automatically bounced open; then the small steel bar is wound on the wooden stick; then the wooden stick is lifted; The missing sleeve can be removed.

Peristaltic Hose Pump

peristaltic hose pump could be used in lots industry . for example : filter press, catalyst industry,shield machine,construction industry , power conveying industry , animal husbandry application and so on . Concrete peristaltic hose pump ; High efficiency widely used concrete peristaltic Industrial Hose Pump ; Squeeze Industrial Hose Pump ; Rubber Hoses Transfering Corrosive Products hose peristaltic pump ; Heavy Duty Continuous Transfer Pump ; Wear-resistant rubber hose pump chemical peristaltic pump construction concrete pump

Hose pump have strong self priming, pump been used to transfer the liquid with big solid particles, like: Concrete, sludge, mud, Cow dung etc.

A wall smooth, reliable strength of special rubber hose inside the pump installation, by rotating the squeezing roller along the hose is a pair of such rotation makes medium to one direction, and there won't be back.Flattened hose under their own flexibility and side guide roller forced restorable. At this point, the tube materials materials will produce high vacuum suction cavity, and then, the material in the subsequent roller pressure escape from the hose.So the cycle, material overtaken by suction and discharge.
