Find that defect can be reprocessed with repair welding after processing, if but occur defect again in key position after finishing, at this moment will be unable to repair welding
Reprocess, repair rate and percent defective are high, cause the quality problems that equipment is serious；Because discharge pipe is casting, casting cycle is long, weight
Amount is larger, increased the weight of equipment.In use, if it find that when mud pierces the problems such as leaking, discharge pipe is dismantled, installed
Cycle is long, and maintenance cost is higher.
Utility model content
The purpose of this utility model is to provide the attachment structure between a kind of slush pump fluid cylinder, to solve slush pump fluid cylinder between connect
Structure setting discharge pipe is connect, causes weight of equipment big, repair rate, percent defective are high, maintenance replacement cycle problem long.
In order to solve the above technical problems, technical solution adopted in the utility model is：
A kind of attachment structure between slush pump fluid cylinder, it includes the first fluid cylinder, the second fluid cylinder, and one end of the first fluid cylinder passes through
Bolt is connected with first flange, and first flange is connected by studs and heavy nut with one end of safety valve connecting pipe,
The other end of safety valve connecting pipe is connected with safety valve, and the other end outer wall of first fluid cylinder is provided with bushing, bushing away from
One end of first fluid cylinder is socketed in the inner chamber of adpting flange, and one end of adpting flange is bolted on the outer of the first fluid cylinder
On wall, the other end of adpting flange is plugged on one end of the second fluid cylinder, is bolted on the outer wall of the second fluid cylinder, second
The other end of fluid cylinder is connected by bolt with second flange, and the opposite side of second flange discharges flange phase by bolt with mud
Connection.
Preferably, between first fluid cylinder and bushing, between bushing and adpting flange, adpting flange and the second fluid cylinder it
Between connecting portion be equipped with rubber gasket.
Preferably, the junction of the first flange and safety valve connecting pipe is provided with metallic packing ring, the second flange with
The junction of mud discharge flange is provided with metallic packing ring.
Preferably, the bushing, adpting flange use superior alloy steel, by phosphorating treatment.
First fluid cylinder in the utility model, the second fluid cylinder two ends size for connection it is identical.When the quantity of fluid cylinder in slush pump
During more than two, above-mentioned attachment structure is used between adjacent fluid cylinder.
The utility model in use, by the first fluid cylinder, the shuttling movement of the second fluid cylinder, can be by mud from mud
Flange discharge is excluded, when operating pressure exceedes the safe-working pressure of safety valve, pressure release can be carried out by safety valve, to protect
Card equipment and the safety of personnel.
The beneficial effects of the utility model are：
（1）The utility model uses bushing, adpting flange by the firm connection of the fluid cylinder of two slush pumps, bushing, connection method
The weight of the blue discharge pipe for being significantly less weight than casting, greatly reduces the weight of equipment, bushing, adpting flange, the company of fluid cylinder
The place of connecing is equipped with rubber gasket, enhances the sealing property of equipment；Prevent high-pressure slurry to leak phenomenon to the thorn of fluid cylinder, improve
Equipment dependability；Consumable accessory is repaired, changes convenient, time saving and energy saving；
（2）Bushing, adpting flange use superior alloy steel in the utility model, and have passed through phosphorating treatment, improve zero
The reliability and rustproof property of part, reduce the percent defective of raw material, improve the quality of equipment, reduce maintenance cost.
